How to Use Carbon Filters for Cannabis

Hands-down the best way to control the smell of your growing cannabis plants is to use a carbon filter (learn more about different options for covering up cannabis growing smells). When installed correctly as part of an exhaust system, a carbon filter will not only prevent the smell of cannabis from leaking outside, but it will also prevent it from smelling up your home. A carbon filter can be more effective than any other method for controlling smells, and it won’t alter the smell of your cannabis.

A carbon scrubber can completely hide the smell of growing cannabis plants, even really smelly ones!

A carbon filter is usually shaped like an enormous tube, and they’re usually pretty heavy. The way they work is they are filled with carbon inside. When air passes through the carbon it neutralizes any smells, and when the air is passed out the back it is completely odor-free. However, for a carbon scrubber to work the air needs to be pulled through the filter, which is usually done using a strong exhaust fan.

In the left pic the carbon filter has a sleeve to help keep out extra dust, while on the right is a “naked” carbon filter so you can see how air can pass through the sides.

When using a carbon filter, the way you set up your exhaust is important; if you don’t set it up properly it won’t work well, if at all!

1.) To Prevent Smells From Leaking into the Grow Room

The exhaust fan needs to be strong enough to create a vacuum in the grow space (in a grow tent you’ll see the side bowing in). That means that all the smelly air is getting vented out the tent so fast that the suction prevents any from going back into your room. Even without a carbon filter, if you have good suction you won’t smell anything outside the tent!

2.) To Prevent Smells From Leaking Outside

Once you have suction in the tent and you’re venting all the smelly air outside, the next step is to “scrub” smells out of that air before it leaves the house. This is where the carbon filter comes in!

This is the most common way to set up a carbon filter:

Carbon Filter > Grow Light > Exhaust Fan > Outside

This simple diagram shows how many growers set up up their exhaust system

This is an example of a carbon filter in action

As air is pulled in through the sides of the carbon filter it is scrubbed of all smells. That air then passes through the ducting, blows over the hot light, and the hot unscented air is then vented outside.

No air leaks in your exhaust system! It’s important that the only way air can enter the system is through the carbon filter, and that air should go straight outside. If there are leaks in the ducting or around the grow light, then smelly air can escape that way instead of passing through the carbon filter first.

That’s pretty much it! You now know the basis of how set up your own effective and efficient exhaust system so odors never escape again!

What Size Carbon Filter Do I Need?

What size carbon filter for a 4×4 grow tent? In most cases, a 4-inch carbon filter will be more than enough for a 4×4 tent. Since a 4×4 tent has a relatively small internal volume a 4-inch carbon filter should easily remove all the odors from the air before they are exhausted from the tent.

If you plan on running an HPS (High-Pr e ssure Sodium) light you might want to run a larger 6-inch carbon filter with a high CFM fan. In that scenario, you’ll need to vent a lot of excess heat, and you’ll need to get a larger carbon filter and fan to cool down the tent.

It’s also important to size your fan accordingly so the carbon filter operates at peak performance. For that reason it’s a good idea to get a carbon filter fan combo, so you can be sure that the carbon filter and fan will work together to keep odors from leaking out of the grow tent.

The primary claim of this filter is that it provides 100-percent filtered airflow, the best on our list meaning there are no pockets of air that escape coming in contact with the filter, helping this filter earn its way on to our list. Inner and outer mesh provides a 53% open area for increased air flow, and decreased smell. The Australian carbon itself will last for multiple years, according to the manufacturer.

This filter is versatile for many different applications thanks to a reversible flange and base. It can be used as an intake or exhaust filter and with varying fans types for different applications.

The Vivosun does come with a pre-filter that removes most large particulates before they enter the unit itself, protecting it and extending its lifespan. If you want to keep your carbon filter working for as long as possible, you do need to pay attention and replace this pre-filter when necessary, about once every growth cycle.

Several Vivosun carbon filter users have also reported that the activated charcoal doesn’t last for very long and odor elimination in their grow tent fails after about month six, so keep that in mind when buying this filter that you may end up replacing it after each growth cycle. It may be more affordable in the long run to obtain a higher quality filter to avoid smell in your room.

iPower has some of the best quality odor control carbon filter products in the market. It is also one of the leading companies in the manufacturer of marijuana farming equipment. The 4-inch carbon filter is one of their most quality products that come with many benefits. The affordable product measures 4 inches and has multifunctional features.

The combo is not only useful in a grow room but you can also use it a green house, the bathroom and in your kitchen. To give it more efficiency, the kit comes fitted with 1050 + IAV Virgin Australian Charcoal RC 412, which is one of the most absorbent carbons found across the globe. The kit has a reversible similar product that measures 12 inches and it is advisable to replace the products pre-filter after every six months. The filter does not produce any noise at all thanks to the CFM inline duct, made from UL premium material.

What makes iPower even more attractive is that it comes with a long 2-year manufacturer’s warranty.

How to Choose a Top Carbon Filter For Grow Room

While you can get away without having a carbon filter in your grow room or tent, a carbon filter is incredibly useful in filtering out odor and also preventing harmful microbes from entering and infecting your plants.

There are plenty of cheap options on the market for you room, but it’s better to find a carbon filter for grow room that offers high performance for a longer time.

When looking for a carbon filter for grow room, there are a couple of things that you should look or. If the filter you’re looking at meets these criteria, chances are you’ll be happy with the product you’ve bought.

Amount of carbon: The more carbon in the filter, the more effective it is, and the longer carbon filter for grow room will last. The thicker the filter bed, the more carbon the filter will have. Look for filter beds that are 1.8 inches (46mm). They will offer the best bang for your buck.

Pre-filter: A pre-filter is a barrier between the carbon layer and the outside air. It’s designed to remove larger particles that would otherwise clog up your carbon filter and ductwork in your grow tent. Many are removable and machine washable, and it’s a good idea to maintain these properly.

Materials and durability: When looking for a carbon filter for your grow room, try to find one that uses the best materials on the market, aluminum for its base and flanges.
