FAQs

Consider the following scenario: you have a 5ft x 5ft x 8ft grow tent: Multiply 5x5x8 to get the answer.

2. How good are carbon filters?

A carbon filter is very good at removing odors from the air. A Carbon filter also work well in reducing chemical fumes and gasses. A carbon filter can be used for a variety of purposes including home, office, or car use.

3. Are carbon filters as good as HEPA filters?

Both HEPA filters and carbon filters are capable of doing tasks that the other cannot. HEPA filters are more effective at eliminating larger, physical particles such as pollen, dust mites, mold, and other allergens than other types of filters. Carbon filters are more effective in removing smells, smoke, and other gaseous particles than other types of filters.

4. Are carbon filters good for air quality?

A carbon filter can be excellent at removing volatile organic compounds (VOCs) from the air. These are gaseous chemicals that most conventional mechanical filters, such as HEPA filters, are unable to filter out completely. With the use of a carbon filter, some of the gases released by cigarettes and other sources such as drying paint or household cleaning chemicals can be eliminated from the air.

5. Can I wash a carbon filter?

If you wash a charcoal filter with soap and water, the charcoal’s ability to filter air or water will be reduced or eliminated entirely. Rinsing the filter with hot water accomplishes the same thing as well as aiding in the release of any absorbed contaminants into the air. When the pores in the charcoal have completely absorbed all of the air contaminants, it is necessary to replace the filter.
