Why Do You Need A Carbon Filter For Grow Tent

Carbon Filters: Should I Use One in My Grow Room?

So you’ve done setting up your grow room, and you’ve begun nurturing some plants. You don’t notice it at first, but later you discover your growing region has a rathertellingodor. Whether it’s the strong fragrance of your plants or a little bit of stink from humidity, chances are you’ll want to keep the aromas of your grow area to yourself. If you want to keep your operation secret, or you just want to keep the scents from your growing space out of your residence, you may consider putting acarbon filterin your grow room.

What Are Carbon Filters?

Like other air filters, acarbon filter is meant to cleanse the air that comes into it and exhale new air into the area. These metal cylinders are packed with carbon media and connect to ahigh output fanin order toremove smells and particlesfrom the air in your grow space. Carbon filters are available in a range of sizes based on the size of your grow room and the quantity of filtering you’re looking for. When set up properly, all the air from your grow room will run through the filter, and the scents in your grow room will disappear.

How Carbon Filters Work

It’s actually fairly simple: Carbon filters operate by collecting unpleasant odours (odor particles) and dust particles in order to enable fresh, odor-free air to flow through the tube. There are a number of materials carbon filters employ, but most — includingYield Lab carbon filters— usecharcoal. It’s a porous substance and beneficial for many things — from getting rid of specific gases in the air to being used as liner for face masks. Active carbon has a huge surface area with hundreds of holes.

This process permits molecules like dust, grime, and odor molecules to adhere to the carbon, preventing them from moving easily back into the air.

You force the odorous molecules from your grow area to attach to the active carbonwithin your carbon filter with anexhaust fan.

Using a Carbon Filter in Your Growing Area

When it’s time to start utilizing a carbon filter in your growing area, there are certain key procedures you need to keep in mind.

Find the Right Size

All carbon filters are not made equal. Depending on thesize of your growing areaand thecubic feet per minute (CFM) value of your exhaust fans, there are different-sized carbon air filters that will be perfect for you. In order to determine the CFM value, you will need to follow these steps:

  • Measure the height, breadth, and lengthof your grow room orgrow tent
  • Multiply these numbersin order to get thecubic footage of the space you’ll be utilizing
  • Multiply this quantity by the exchange rate(the number of times you want the air to be totally swapped per hour) (the number of times you want the air to be completely exchanged each hour). To have a steady flow of fresh air, you’ll want tomultiply by 60, which isonce every minute
  • Your CFM isthis figure divided by 60

The simplest technique to find out which size carbon grow room filter you should use is to make sure that your filter’s CFM value is eitherequal to or lower thanthe CFM value of your grow room and your exhaust fan. For example, if you had a5ft x 5ft x 8ftgrow tent:

  • Multiply5x5x8. You get200, which is thecubic feetof your growth space
  • Multiply thecubic feet (200)by the number ofexchanges per hour (60), which gives you12000
  • Divide that number(12000)by theminutes of exchange in an hour (60)for a total of200 CFM
  • Take the200 CFMyou have and seek for a filter thatmeets or exceedsthat CFM

Rule of thumb: It’s always preferable to go beyond your CFM need than under.

If you purchase a smaller filter than you’ll need, you’ll eat up the carbon rapidly.

Set Up Your Filter

Once you know whatever size filter you need, you then need to make sure that youset it up properly. In order for you to get the most of your carbon air filter, you need to ensure that it is filtering all of the air that is in your grow room. This implies you need to connect it to agrow room fanand connectductingto it, then seal it properly using duct clamps. Place the fan and filterabove or near your plants. Next, place the fan so it takes air from your grow area and exhausts it into the filter.

Maintain Your Carbon Filter

When all of the pores, or adsorption sites, in the carbon are full, your carbon filter will no longer be able to catch new molecules. You can maintain your carbon filter by making sure you clean it periodically – typicallyonce a month. In order to clean your filter, you should pull the filter out of your grow chamber, then shake out any trapped dust and dirt. Note: Contrary to common perception, using water and soap to clean charcoal in a filter might actually have a detrimental impact. Remember that charcoal breaks down, and with the assistance of water, you may speed up that erosion.

Depending on how much work it’s required to do,carbon air filters should be replaced everyone to one-and-a-halfyears.

Should You Use a Carbon Filter in Your Growing Area?

The answer to that question is a resounding yes! Carbon filters are thebest optionfor keeping the stench from your growing area out of your house and away from your neighbors. More significantly, they’re the finest way to ensure sure even the cleanest air is utilised by your plants to flourish. It’s worth mentioning that there are various short term options that you may apply, likeair purifiersorneutralizing sprays and powders. That said, these instruments do not totally remove the scent from your growing operation, and they will not completely erase any dust particles that arrive from your grow room.

The best approach to assure that your grow room is safely odor-free and avoid aromas from fleeing your growing space, is to install a carbon filter.

What Is A Carbon Filter and How Does It Work for Grow Room?

Home»Environment» What Is A Carbon Filter and How Does It Work for Grow Room? 9841Views0 Grow tents demand adequate ventilation. And farmers have many strategies to make sure that happens. But there are aromas and odors within grow tent, which you don’t want to come out and keep your house smelling like an extreme hotbox. Forodour managementin such cases, carbon filters are on rescue.

In this 2000+ words essay, we’ll be taking you through a carbon filter 101 instruction. We’ll study the definition, the kinds, how they operate, the cfm calculation, installation/setup instructions and so on. Grab a cup of coffee, and let’s master on grow room carbon filters-

What Is A Carbon Filter?

Carbonfilter is a component ofairexhaust system in anisolated place (grow tent, grow room, greenhouse etc) (grow tent, grow room, greenhouse etc.) They include beds ofactivated carbon (charcoal) with lots of pores within. Photo Source: Amazon.com When air of a grow room or greenhouse is evacuated via a carbon filter, it captures the stench, dust, spores, pollen and other airborne containments. As a consequence, your grow room stays free of foul smell, hazardous chemicals, and unhealthy containments.

What is a Carbon Filter for in Grow Room?

Before going further, let’s understand about thepurposes of carbon filter in grow room –

Odor Management

For a grower, one of the hardest duties is to keep the foul scent away. Specially, when you don’t want your neighbors to know about this ‘hobby’ of yours. Fortunately, a carbon filter is able to catch all the unpleasant particles from the air, provided air moves over the filter in a suitable way. To make it happen, you’ve to deploy exhaust fan(s) to pull air and take that air through the filter before releasing outdoors.

Taking Impurities Out

Apart fromright temperatiure, humidity and nutrients, develop plants require clean, fresh air as well. Impurities like air-borne infections can cause illnesses in plants and damage the wholegrow output. And activated carbon has it’s the power to clean such contaminants out of the air. To enable your plants breathe freely, you’ve to set up a ventilation system where all of the air is taken through the carbon filter on frequent basis.

To Cut Your Bills

There are numerous systems for air filtering. And some of them could cost you a lot. Butgrow room air carbon filtersare the least priced one of them that costs not too much and yet performs pretty great. As growing indoor is a power-hungry enterprise, an effective carbon filter may keep the electricity expense down.

Quick and Easy to Setup

Another excellent aspect regarding carbon filters is- they’re quite straightforward to install. If you think about a carbon filter-fan combo, it may be set on the proper position within minutes. All you have to do is set it up at the proper height, then attach with ducting with clamps.

Types of Carbon Filter for Grow Room

Air filtering in grow tents may be done in different approaches. Based ongrow tent sizes, quantity of plants, ventilation system and budget, the choice of grow tent filters is determined. For grow rooms, we may separate such air filters according to a few viewpoints- Filtration media, fan-filter combination and diameter of filters. Let’s learn about each of them-

Based on Filtering Medium

Most convenient and most efficient grow room air filters are composed of carbon beds. Activated carbon filterbeds, to be exact. For manufacturing the filters within, charcoals are chemically and thermally processed and transformed into activated carbon. One of the qualities of activated carbon is- they have millions of pores.

Resultantly, the surface area extends to 2000-4000 m2 in each gram of activated carbon to pull dust and odor particles onto it. In about 100 percent of growth systems require activated carbon air filters nonetheless. Our Pick: Amagabeli 6 inch Carbon Filter

Non-carbon Air Filter

There are a few different filters where non-carbon components like particle cabin air filters are employed instead. Although carbon filters are cheaper than this, particle cabin filters are not as efficient as them. As an example-particulate cabin air filtersare able to eliminate the dust confinement alone. But activated carbon filters takes everything that particle filters do as well as the odor and exhaust emissions. If you’re in short of enough area to house a carbon filter, you may consider putting the carbon filter outside of it.

Based on Filter-Fan Combination

These are more like single carbon filters that you would like to have as replacements of your present one. While acquiring such solitary filters for your system, bear in mind to match the CFM rating, the sizes, the flanges and the dimensions(both length and diameter) (both length and diameter). However, be sure you pick up a model with a pre-filter given with it. Our Pick:VIVOSUN 4 Inch Air Carbon Filter

Carbon Filter-fan Combo

For most growers, a filter-fan combo is the best alternatives. The adjustment and installation involve a minimal effort, since the fan and the filter are created to be equipped with one another. With many versions, there are additional speed controller devices and rope hangers with the fan-filter duo. You may call such products the 360-degree ventilation solution for any grow system. Our Pick(with speed controller):VIVOSUN 6 Inch 440 CFM Inline Fan with Speed Controller Our Pick(without speed controller):VIVOSUN 6 Inch Air Carbon Filter

Based on Diameter

4 inches carbon filters are with the smallest opening size. They come with CFM rates about 150-250 CFM. And such filters are great for 4×4, 4×7 or 4×8 tents, where you may grow 4-6 plants(ScrOG style) (ScrOG style). Our Pick: iPower 4 Inch Air Carbon Filter

6” Carbon Filters

Carbon filters with 6” sized diameters are able to extract air about 400CFM rate. When you wish to equip only one carbon filet in your 8×8 or 10×8 grow chamber, this is the one that you may choose for. Our Pick: Phresh Filter 701005 Filter

8” Carbon Filters

8 inches filters are more ideal for grow rooms rather than small or medium-sized grow tents. As they come with a CFM rating of 600-700 CFM, they might be fairly sufficient for grow rooms of 12×12 size. Our Pick: VIVOSUN 6 Inch Air Carbon Filter

10” Carbon Filters

10” carbon filters are the older counterparts of 8” units. Providing an air extraction rate of 1100-1200 CFM, growers are more inclined to cling to these models. Our Pick: Phresh Filter 10 in x 24 in 850 CFM Carbon Filter

12” Carbon Filters

This is the largest sort of carbon filters of them all. Usually, when you require ultra-efficient air extraction at a rate of 1400+ CFM, these are the ones you should opt for. Our Pick: Phresh Filter 12 in x 24 in 950 CFM Filter

How Does A Carbon Filter Work in A Grow Room

Carbon filters are exceptionally strong combaters when it comes to battling allergies, viruses, harsh pollutants and smells. But how the heck they work? Well, as the name implies, there are layers of activated carbon beds(charcoals) in each carbon filter. The carbon particles create a surface area full of pores. Each gram of activated carbon contains 3000 m2 of such surface. Now the issue is, what isactivated carbon? Activated carbons as just conventional charcoals, but taken through a procedure it’s gas trapping capacity.

That forms a lattice of pores in the carbon.

As you’ve read a while back, a single gram of activated carbon can contain hundreds of square meters of internal surface area.

The process is termed ‘Adsorption’(not Absorption) (not Absorption).

Through this process, the carbon bed gets to absorb various organic chemicals(gas, dust) (gas, dust). As an end consequence, pollution particles and odor producing gas molecules are stuck onto the surface of activated carbon(charcoal) bed. And what you get is a pollutant-free, odor-free grow tent.

Carbon Filter Cfm Calculator for Different Grow Tent Size

At this stage in the talk, we’ll learn how to determine the proper size(capacity) of carbon filter for your grow tent. And we want you to be super-attentive to the computations we’re going to do-

See also:  How To Keep Bugs Away From Your Tent

Step 1: Determine Your Grow Tent Air Volume

First of all, determine the entire volume of the grow tent. This will let you know how much air is present within the tent/room at any one point. The formula is simple- Volume of grow tent= Length x Width x Height Example: 10ft x 10 ft x 8 foot= 800 Cubic Feet

Step 2: Decide How Much Air to Extract In Every Minute(CFM)

Now, you’ve to determine how many times you want to replenish the complete air every hour. For small tents, it can be 40- 60 times in an hour(once in every 1.5- 1 minute) (once in every 1.5- 1 minute). For bigger grow tents like 10×10, 8×8, 4×8, we like it to be 30-20 times in an hour(once in every 2-3 minutes) (once in every 2-3 minutes). Let’s imagine that we want to empty up our 10×10 grow tent air once every 3 minutes. So, air volume to extract in each minute(CFM)-Air volume to extract(for fan) in 1 minute= 800 cubic ft./3= 266 CFMSo, the fan should be able to take the air out at 266 CFM rate.

Step 3: Calculte The Carbon Filter CFM

Now, it’s time to establish the capacity of the carbon filter and the fan. In this regard, let us inform you that, utilizing carbon filter on an extractor fan inhibits the fan’s efficiency. To be specific, employing a carbon filter diminishes the fan’s effectiveness by around 25 percent . So, you need to equip a carbon filter with 25 percent greater CFM rating in order to enable the fan extract the appropriate volume of air in each minute. So, the CFM rating of the carbon filter would be-CFM Rating of Carbon Filter= 266 CFM x 1.25= 332.5 CFMT hings to remember-

  1. The air extraction frequency may vary dependent on the size of the tent, and the types of plants
  2. The resistance of carbon filter on the performance of the fan may vary dependent on size, diameter and connector type
  3. The resistance on the performance of fan may also rely on the length and substance of ducting. As an example, straight hard cast ducting of 25ft may lose 3 percent of CFM efficiency of the fan
  4. The resistance on the performance of fan may also rely on the ducting angle. As an example, a 90-degree bend may loss 1 percent -4 percent of the overall efficiency

However, here’s a pre-formulatedcarbon filter size calculator. Hope you’d have a few minutes to look that up. Also, this video on carbon filter size might be a big help-

Where and How to Use Carbon Filter in Grow Room?

Most growers prefer placing the carbon filters within the tent, where it can be paired with the ducting and the inline fans. However, if you’ve little room to keep a full-size air filter,carbon filter placementcan be outside as well. However, considering that you’re putting it up indoors, below are the easy methods of installing a carbon filter- Step 1:Take out the filter from the packaging, place the pre-filter(if any) on it. Step 2:Place the filter on the exhaust together with rope ratchets.

Step 3:Secure the connections via duct clamps.

Step 4:Power the fan up and check for any leaking during the full route.

Carbon Filter Maintenance 101

Carbon filters are mechanical devices to play a significant part in odor/impurities management. To maintain them in their best condition, keep these maintenance guidelines in mind-

Clean the Filter

Cleaning carbon filters is one must-to-do chore to make the greatest use of it. Firstly, remove it from grow chamber, and take that into an open environment. Shake it vigorously to eliminate any trapped dirt or dust within. Now, sprinkle water on the carbon beds and plunge it into the water.

Don’t forget to mix the water with a little soap before placing the carbon filter in it. Keep it under water for 15 minutes, and pull it out. Now, dry it under heat or sunshine. Read our comprehensive cleaning guide for additional in-depth advice.

Vacuum and Dry Up

If you don’t want to deal with the hassle of cleaning it off every month, a vacuum cleaner might be an option. In every alternative week, vacuum-clean the activated carbon beds to eliminate excess carbon and dust particles. Before vacuum cleaning, don’t forget to take the carbon bed out.

Don’t Use It Beyond It’s Lifetime

If you’re serious about the odor management, you shouldn’t expect a carbon filter to accomplish it forever. Like any other equipment, it has a definite lifespan. And it’s ideal to modify it straight after that time. Usual carbon filters are expected to perform adequately for 1-1.5 years. However, you should have an eye on the durability of a carbon filter while you’re buying it.

Can You Grow Without Carbon Filter?

We’ve seen many first time growers ask themselves-do I need a carbon filter in my grow room? Well, the inquiry itself responds you back with another question-“Do you mind if the stench within the grow tent gets out and spreads around?” If the answer is no, then there is no other solution than employing a decent grade carbon filter in your grow system. However, if you’regrowing outdoorwhere you can take the air without filtering the scents and release them to the environment, then you might not require a carbon filter.

What is a Carbon Filter

As the name itself says, it is a device that filters aromatic hazardous particles from the air. The activated carbon filter is a trusted technology that removes a wide range of pollutants from the air such Carbon filters are created using high-quality carbon granules and pellets in sturdy chemical resistant casings. Actually made up of a huge cylinder with a duct-like entrance and is filled with grains or pellets.

The white color additional protective pre-filter layer is also there to make its interior chamber dust free. These are the only odor control option for grow room setup whereas other technologies have a pretty hard time competing with stink. Let’s see how it works, next!

How Does Carbon Filter Work

Now you are completely aware of the structure of the filter, It’s time to know how exactly it functions for a grow tent. Activated carbon filters function on adsorption principle rather than absorption. In this process, odor particles are drawn from the air and become trapped on the surface of the charcoal’s pores generating a thin film coating. Eventually, all pores become sealed entirely. Its necessary to update your filter as charcoal gets compact which may result in no odor elimination at all.

Air should go from filter then to fan and then outdoors or circulate within the tent.

Why Do You Need a Carbon Filter For Grow Tent

What Does Carbon Filter Do in Grow Tent

Why filter here in every grow tent? What can it do for plants there? Whilst buying filter growers frequently consider more about these topics. Let’s explore how a filter can safeguard your plant as well as the environment surrounding your plantation.

  • It eliminates odor
  • Filter is precisely engineered to block odor particles in its pores. Now the air that comes out of it is fresh and beneficial for plants
  • It enables fresh air circulation: If there is no filter only air will flow through the tent, not fresh air. When fresh air comes out of the filter, fans circulate it and it reaches to plant again and again
  • It catches dust particles: Because of pre-filter cover, dust particles also get caught here. In this way, a carbon filter may protect your plant from dust particles. Some filters are much more sophisticated and may catch dangerous allergen extracts too

Benefits of Carbon Filter For Grow Tent

When you establish an artificial environment for plants to flourish indoors, you have to consider a number of aspects. In a natural context, plants tend to produce gases in the open air. But indoor plants may be troublesome if you don’t perform enough arrangements to kick off an odor that creates carbon and other gases discharge.

  • Carbon filter catch odor particles that are created as a result of fertilizer, water, or carbon release during photosynthesis. It not only maintains your indoor tent space odor-free but also the outdoor area
  • It reduces the smell of sulfide or other toxic extracts of fertilizers likewise that may cause allergy symptoms in persons living close
  • Some filters are considerably more efficient to absorb dust particles with an extra layer of pre-filter. In this approach, air quality rises
  • They are easy to put anywhere outside or inside the tent and even you may hang them below the roof area of the tent if you don’t have enough room
  • They don’t effect the development of your plant directly as other techniques of purifying air can. So, they are trustworthy and easy to manage
  • They can even survive more than a year if you install them appropriately and carefully. They are cost-saving gadgets as they dont need repair or any other spare components
  • Carbo

Does Fan Can Do The Job of Carbon Filter

Will a fan be adequate or do I still need a carbon filter? Growers frequently find it a bit puzzling. They felt that fans can expel stench from a grow tent therefore why do they need a filter? Yes, it’s true that fans can execute the air circulation task effortlessly. If fans promote circulation filters boosts air cleansing. The simply circulation is not enough, air purification is also required. The filter fan combination assures the circulation of pure air throughout the tent. Fans can’t accomplish the function of the filter.

If you continue on solely with a fan and without a filter, your plants, especially cannibals, will become worse gradually.

Does Carbon filterAffect The Growth of the Plant

Do carbon filters effect photosynthesis or plant growth? No, there is no direct influence of this gadget on the crop. However, indirectly, it may impact them. Air quality is the key component that contributes to plant development. When you install a carbon filter, it will make the air surrounding the growing area free from chemical odor, carbon particles, and other dangerous fertilizer’s gases. Indirectly it will damage your plant health but not directly.

Your plant will eat more carbon daily, that’s not a good thing. Your plant will still grow in its absence but it will not be much pleased, certainly! Editor Tips:How To Clean Carbon Filter For Grow Room? Read it necessary if you are already using a carbon filter.

How Long Does a Carbon Filter Last

Usually, carbon filters may expire from 6 to 12 months depending on elements like temperature, humidity, setup and many more. The bad news is that you can’t reuse them after rinsing as it’s not effective. Once they are done up, you will have to replace them and no other option known thus far. However, they expire even before 6 months if your environment is extremely dusty, dry and hot. One other problem is quite typical when growers install the improper size of the filter in their grow room, it is likely to expire more quickly.

Is A Carbon Filter Necessary?

To answer the above question fast, No. A Co2 filter (also termed carbon scrubber) isn’t, theoretically, essential. You can produce a perfectly good crop without having a carbon filter in yourgrow tentor grow room. Most indoor growers nonetheless will require more than simply agrow lightand agrow tentas carbon air filters are fantastic odor neutralizers.

So, whether you want to keep yourcannabisgrowing business hidden, or you simply want to avoid the unmistakable marijuana scent, acarbon filteris a must-have for a home, indoor farmer.

How Does The C02 Filter help?

A carbon filter assists in various areas, with the most essential reasons being stated below:

  • Air Purification -A C02 filter is able to filter out contaminants from coming into yourgrow tentand possibly harming your crops
  • Smell Control – A decent charcoal filter will help lessen or even remove the unique marijuana smell that comes from terpenes

How Does A Carbon Filter Work?

The great majority of the C02filters employ activated carbon(AKA “activated charcoal”) for its filtering or scrubbing. Activated carbon is particularly designed to contain small holes or pores, which results in more holes per filter. In short, more pores on a filter means higher filtering. If you are intrigued, check at the appendix for further info on activated carbon. If you know what a sponge does, you will know the principle behind a carbon filter. The carbon filters simply collect, like a sponge, various containments and stop them from going outside the tent; furthermore it stops foul air from coming into your grow area.

How Can You Gauge The Efficiency Of A Carbon Filtering System?

CFM or cubic feet per minute is the norm that you should seek for when it comes to air filters. CFM specifies how many cubic feet per minute a carbon scrubber can filter. The CFM size that you require depends upon the size of your grow space. So, more CFM is not necessarily better. Check thisarticleout for a guidance on the CFM size you should get.

Top Brands

The Phresh Carbon Filter is one of the top-rated, filters on the market. The Phresh Filter is pricey but reasonable. However, it is not aHEPAfilter.

Proper Grow Area Ventilation System

Along with a decent air carbon filter, you will also need a proper ventilation system for yourgrow tentor grow room. Thegrow tent ‘s veniliation system provides a vacuum-like effect in your grow space as it attempts to suck the unwanted air out. Otherwise, without a ventilation system, the general environment would be stagnant. On a side note, ventilation for a grow room has various other benefits other than optimizing air circulation. They also aid with odor management and aim to prevent mildew from creeping up on your plants.

Both things together allow the air to flow, which in turn implies that the filter can do its function.

  • Circulating Fan or Oscillating Fan -The circulating fan’s goal is to replicate the winds that your plants would experience if the plants were growing outside. How many and the power that you will require depends upon how big and how many grow tents that you have
  • Exhaust Fan or Inline Fan- The inline fan is used to take in new air and expel out the old air through through ducting. An inline fan paired with a carbon filter can make the air from a growing region odorless

Final Thoughts

As I indicated a charcoal filter isn’t necessary needed. However, it should be essential for all indoor growers, who live in the city or who have visitors over regularly. So, do your study, and obtain the greatest one for your personal scenario.


Ozone generators are promoted as an air, quality, control equipment. Some of the producers say that they will assist with both air quality and also help reduce odours. The question though, is do they function, and if so, to what extent should you utilize them in your grow room orgrow tent?

How Do They Work?

It creates ozone by splitting oxygen molecules into a single atom. This single atom then will transform into additional oxygen molecules that in turn generate Ozone. Currently, the conversion is done by either electricity or UV light.

Is Ozone Dangerous?

Yes, too much of it can harm your lungs and cause chest discomfort, breathing troubles, and it will give you a soar throat.

Additionally, it can be extremely dangerous to persons that have asthma, COPD, or other respiratory illnesses.

Do They Help With Air Quality?

Per the EPA, no. TheEPAstates that ozone levels that do not exceed the prescribed acceptable limits will not scrub out of eradicating any interior air contaminants. Obviously, ozone generators are only meant to create safe quantities of gas. So, based upon the EPA, the only way it would be effective would be if it caused harmful amounts of ozone. Do They Work For Odor Control? The EPA does not say anything concerning ozone generator and odor control. I did locate anarticle, which said that the modification of the makeup of the oxygen molecule may result in reducing smells.

Final Thoughts

Stay clear from ozone generators and utilize that money instead to acquire a bettergrow tentventilation and carbon air filter.

What Is Activated Carbon?
