1. What Is Carbon Filter in an Air Purifier

Activated carbon, also called activated charcoal, is a form of carbon and is often used for purification and filtration because of its strong ability to absorb gas molecules.

An activated carbon filter is made up of granulated or powdered solid activated carbon blocks. The numerous tiny pores on the surface of the activated carbon can absorb odors and harmful chemicals as air passes through it.

When gas molecules adhere to the carbon filter, they are trapped and unable to circulate back into the air. The more carbon pores in the filter, the better the ability to neutralize odors and gases.

Apart from air purification, it can be used as:

  • Cigarette filter
  • Water purification
  • Industrial gas processing

Because carbon filters are 100% safe and effective, the EPA recommends using them in air purifiers to combat harmful chemical gases such as volatile organic compounds (VOCs) found in paints, furniture, and cosmetics.

In summary, the benefits of activated carbon filters for air purifiers are making the room chemical-smell-free and odor-free.

2. HEPA Filters vs. Carbon Filters: What's the Difference?

Both are designed for different purposes. Carbon filters use highly porous charcoal to remove odors and gas molecules, whereas HEPA filters use tangled bundles of fine fibers to filter out allergens such as dust, pollen, pet hair, pet dander, and mold.

The diameter and tangle level of the polypropylene or fiberglass used in HEPA (high-efficiency particulate air) filters determine the filtration level. According to European standards, an air purifier that uses standard filters must remove up to 99.95% of air particles.

Shortly, if you only need an air purifier to remove odors or chemicals from the air, you can get one with a carbon filter. A HEPA air filter is a good choice if you only want to remove air particles such as dust and pet hair.

However, both types of air pollution are always present in your home. VOCs are ubiquitous in homes with cosmetics, paints, furniture, and other chemical materials. Kitchen and pet odors, as well as allergens like dust, pollen, and dust mites, are obvious poor air quality problems.

If you want to completely address the air quality problems in your home, the best way is to get an air purifier with carbon filters and HEPA filters.

4. Air Purifier with HEPA and Carbon Filter - FAQs

Q1. Can You Wash Carbon Filters for Air Purifiers?

It is not recommended to wash your carbon filters because carbon filters can absorb water and cause dust mites to grow. Furthermore, the VOCs and other chemicals absorbed cannot be washed away.

Q2. Do Carbon Air Filters Really Work?

Absolutely yes!

If your home is always filled with smoke or other foul odors, using carbon filters will make a significant difference. Even if you don't notice any odors, a carbon air filter can remove harmful VOCs from the air in your home.

Q3. Do Carbon Filters Clean the Air?

Sure! Carbon air filters can remove VOCs and odors from the air. Most mechanical filters, such as HEPA filters, are incapable of handling these gaseous substances.

Q4. How Long Do Carbon & HEPA Filters Last?

These combination filters typically have a life span of 3 to 6 months. If you live in an area with poor air quality, you should check your filter monthly to see if it needs to be replaced.

Q5. Is Carbon Filter Necessary in Air Purifier?
