FAQ:

Q: What is the best air filter for home?

A: True HEPA (or High Efficiency Particulate Air) filters provide the best filtration for your home by removing up to 98% of air pollutants from your home. They have a MERV rating between 17 and 20. However, they can only be used in a whole house filtration system or a standalone air purifier.

Q: What is whole house air filtration system?

A: Whole-House Filters. The most efficient way to filter household air is through your home’s forced-air heating or central air-conditioning system. The filters are built into the return-air ductwork, trapping particles as air passes through.

Q: Is the furnace filter the same as the air conditioning filter?

A: If your house or home has central heat and air conditioning, then the answer is yes . Even if you have a separate cooling (HVAC or AC) unit and a furnace unit for your heating system, they both will normally share the same air-handler. Because that’s the same exact area where your air filter resides, both systems will share the same filter.

Q: Do air purifiers work?

A: Air purifiers essentially work by sanitizing the air , which may include pollutants, allergens, and toxins. They’re the exact opposite of essential oil diffusers and humidifiers, which add particles to indoor air. Air purifiers also act differently than filters. While filters only remove particles, purifiers can sanitize them, too.
