Sensing some foul smells around your households?

Your grow room can often be the culprit.

The disgusting odor from the grow rooms are a huge concern for growers who live in a lightly congested area or apartment buildings.

Don’t give your noisy neighbors a chance to complain about your grow room.

In this article, we’ll discuss everything you need to know about before choosing an activated carbon air filter.

What is an Activated Carbon Air Filter?

How do they work?

Activated carbon air filters are small pieces of carbon typically in powdered or granular form. They are treated to be extremely porous and so immense that just one gram off activated carbon can have a surface area of  500m2 or even higher.

The vast surface area of activated carbon enables them to absorb exponentially more amount of allergens and contaminants than normal carbon.

Adsorption is the process where organic compounds and other contaminants in air or water react chemically with the activated carbon causing them to stick to the filter.

The filters thus effectively remove hazardous compounds.

What to look for in an Activated Carbon Air Filter?

However, it’s not that easy to choose the right carbon filter considering the abundance of option available in the market.

Considering the factors below you can narrow up your selection process.

1.  Carbon Thickness

The thicker the carbon, the adsorption rate will be greater. The carbon filter will be more effective in removing odors when the carbon in it is thicker. You should expect a higher price for the thicker once since it offers higher efficiency.

2. Pre-filter

Carbon filters often come packaged with pre-filters that are placed outside the carbon filter. This pre-filters prevents particles like dust from entering the carbon filter. This pre-filter can thus improve the life span of the carbon filter and other parts of the appliance.

3.Portability

The compact models are more efficient in absorbing odor and smell and converting them into carbon granules. This model produces less noise and vibration comparing to its competitors. If you love portable gadgets, have a look at our complete guide to buying a rechargeable battery fan

4.Durability

It’s always not a good idea to go for a cheaper one while looking for a carbon filter. A better life span could be expected for an expensive one. The sturdy carbon filters have higher performance and their maintenance is lighter compared to other models.
