ECO Farm Carbon Filter 4" VS CoolGrows 4 inch Air Carbon Filter

An activated carbon filter efficiently traps odors, bad smells, and unhealthy particles from the grow room. Choosing a high-quality activated carbon filter ensures proper functioning for a prolonged time.

Why should you avoid buying cheap activated carbon filters?

Cheap activated carbon filters are not efficient enough to remove unwanted smells, and toxic air pollutants inside the grow room. Besides, they won’t last long. Investing in decent activated carbon filters ensures proper functionality and a longer lifespan.

What Size Carbon Filter do I Need 

The right carbon filter size is ideally one that complements your fan’s cm3 requirements. You can use the carbon filter size calculator to determine the requirements of your application right off the bat.

Alternatively, you can use a simple length x width x height/3 calculation. From this formula, you’ll get the amount of air (cubic feet per minute, CFM) you’ll need to ventilate your space and facilitate a 3-minute air exchange (your space will exchange contaminated air with fresh air in every 3 minutes).

And, again, you’ll need to match the number you get to your filter.

Take a look at this example.

Let’s assume you’ve got the following measurements:

Room size: 10ft x 12ft x 8ft =960 cubic feet

960 cubic feet/3 minutes=320CFM.

The 320CFM is the minimum recommendable CFM that allows for air exchanges every 2–3 minutes (20–30 times per hour).

You can use the same formula for recirculating systems, but this time you’ll have to divide by 1.5 instead of 3. This provides a high cycle rate while ensuring maximum air purification with each pass through the filter.

Anyways, after determining the size of to use, it’s time to figure out the fan size to pair with it. Here, you’ll need to measure the length, width and height (in meters) of your growing environment.

Multiply the length, width and height to get the cubic meter volume. Then multiply the figure you get by 20 or 30. The figure you get is the correct size of fan you need to use to facilitate air exchanges up to 20 or 30 times per hour (the recommended number; other factors may come in to play)

To allow for adequate ventilation, we recommend getting a fan that’s slightly above the figure you calculated. You also gotta factor in a 10–25% decrease in air flow caused by the resistance of transiting through the carbon filter chamber.

Pro Tip: If you’re using an exhaust system, steer clear of fans that exceed your filter’s exhaust rating.

Features to Look for in the Best Carbon Filter?

With a ton of options on offer, choosing the best carbon filter for grow tent can take a bit of digging. To make an educated purchase decision, the following is a rundown of the features to look for in the right carbon filter for grow room.

Durability: How long can your filter last? This is entirely dependent on the material used to construct the product. Steer clear of cheaply made filters that only last a couple of months, and opt for sturdy filters made with premium galvanized steel or aluminum materials.

Although they might be expensive, they’re sure to last up to two years without acting up, which will be worth your investment in the long run.

Quality of carbon: You should expect to find carbon (activated charcoal) inside the filters for scrubbing contaminants from the air. Is the carbon of high quality? And where is it sourced?

The filter should come with the highest quality charcoal or carbon. From our experience, charcoals obtained from virgin Australian beds are the best in adsorbing odors and chemicals.

The best quality carbon has a high adsorbent rate due to more carbon present, and will certainly cover a huge space. Before you choose, try to figure out the volume of charcoal used, degree of activation, particle sizing, nature, and source.

Thickness of carbon: The thicker the carbon, the greater the adsorption rate and elimination of foul odors. A thicker carbon actually makes the filer more effective in terms of odor control. Aim for a thickness of at least 50mm, such as the 6inch AC Infinity Air Carbon Filter which boasts 60mm thickness.

As expected, product with thicker carbon boast of a higher price tag. The good news is that their effectiveness is on a higher level.

Versatility: Does your device have the dual function? A multifunctional filter offers the best bang for your buck, because you can use it on inline or exhaust fan. A good example is the G HYDRO 6 inch air Filter, whose versatility is unbeatable.

As much as you wish to save on cash, I recommend opting for filters with dual role. This key function improves versatility and extends the life of your filter.

Pre-filters: Most top-rated filters now feature pre-filters for reducing particles like dust from coming into contact with the filter. You can put these pre-filters outside of your carbon filter to remove sediments from your grow room.

Filters that come packaged with pre-filters are longer lasting than those lacking them. They aid in eliminating larger contaminants that would otherwise get into the filter.

Portability: The more compact a device is, the lesser the noise and vibration it discharges during operation. Compact filters are also considered better at scrubbing odor and smell.

Plus, transporting the filter into the carbon granules is a walk in the park. Contrary to those with air pockets in between, this type of filter catches odor more efficiently, allowing you to enjoy odor-free environment.

Carbon filter-fan combo: Premium quality carbon filters come with a filter-fan combo. These choices take minimal effort to install and adjust. And the fan and filter combination is designed to complement each other for augmented air scrubbing performance.

Additionally, higher-tier models not only come complete with the fan-filter combo but also speed controlling devices. Such a package is an ideal 360-degree ventilation solution for your grow system.
