4 Qualities To Look For In a Carbon Filter

Basically, carbon filters utilize carbon in absorbing odor and bad smell. But how does it really work? Well, the filter absorbs air contaminants like unpleasant odor, pungent smell, allergens, and even pathogens. The carbon then reacts to these contaminants and traps them in the filter. Then, the filter screens out impurities and cleanses the air that goes through the filter before releasing it back into the air.

This process continues as long as the filter still contains carbon, as well as space for possible contaminants that can be detected in the air. Therefore, exactly because of this complex process, it’s not easy to look for the right carbon filter on the market. You have to consider the following factors in choosing your grow room filters.

1. Size

Your chosen carbon filter should match all the components in your grow room so that it can work effectively. Some gardeners also consider that small grow tents can be used with small carbon filters like 3-inch carbon filters while large ones need large filters.

2. Thickness of the Carbon

The thicker filter typically means more carbon. Thicker carbons have the capacity to perform more efficiently. However, take note that the thicker the carbon is, the higher the price can be.

3. Compact

A compact carbon filter usually produces less noise and vibrations. Furthermore, compact carbon filters are capable of containing the absorbed odor and smell into the carbon granules as compared to the filters that have air pockets in between.

4. Highly Durable

Expensive but high-quality carbon filters are better than low-quality and cheap carbon filters. Remember that high-quality ones perform better and last longer. It is better to choose carbon filters that are made of aluminum since it is lighter and rust-resistant.

Tips and Tricks for Cleaning Your Carbon Filter

Cleaning your carbon filter is just very easy. Just follow these simple steps to successfully clean your carbon filter.

1. Remove the carbon from the grow tent.
2. Bring your removed carbon filter into an open area, preferably the outdoor part of your house as cleaning it might be a little bit messy.
3. Shake off any dirt found around the carbon filter.
4. Spray water onto the carbon filter using a garden hose to loosen the absorbed dirt.
5. Dilute 1 cup of dishwashing soap into a bucket of warm water and submerge your carbon filter. Let it stay for 15 minutes.
6. After 15 minutes, rinse the carbon filter and let it dry.

Final Thoughts

Last but not least, remember that before you set up a carbon filter, always consider the size of the components inside your grow tent. This is very important so that your chosen carbon filter would perfectly fit and work effectively in filtering contaminants. It is also necessary to consider the size of the filter. Small carbon filters are ideal for small grow tents while large ones are for large grow tents. Furthermore, quality should also be highly considered rather than the price.
