Do I Need an Air Purifier?

With indoor air being up to five times more polluted than outdoor air, there’s an alarming call to action to think more carefully about the air we breathe indoors. Contaminants come from all sorts of household activities, like using gas-fired appliances, cleaning products, fireplaces, and smoking cigarettes. Equally concerning is how quickly allergens like dust mites, mold spores, pollen, and pet dander can accumulate in the air and infiltrate our respiratory systems. By filtering these contaminants, you can prevent allergic reactions and various other health issues.

How Do Air Purifiers Work?

Air purifiers work by sucking in air through internal fans, pushing it through a filtration system, and releasing it back into your indoor environment. But with so many air purifiers on the market, choosing the best one for you and your family may be confusing. This is why we strongly recommend a purifier with a verified True HEPA filter.


What Does “True HEPA” Mean?

Many products on the market are labeled “HEPA-like” and “HEPA-type”, but they’re actually disguising the fact that their product doesn’t meet top industry standards. To be considered “True HEPA,” an air purifier must meet strict U.S. Department of Energy standards. HEPA stands for High-Efficiency Particulate Air, meaning that these filters are at the highest efficiency possible. True HEPA filters remove 99.97% of particles as small as 0.3 microns. For reference of how small 0.3 microns is, things are invisible to the naked eye starting at 40 microns! 


What Sets Levoit Air Purifiers Apart?

The Levoit True HEPA Air Purifiers not only have the True HEPA Filter, but also a Fine Preliminary Filter and a High-Efficiency Activated Carbon Filter for effective 3-stage filtration. Each filter serves a different purpose. Here’s a quick breakdown:

  • The Fine Preliminary Filter captures large particles such as dust, lint, fibers, hair, and pet fur. This filter also maximizes the life of the True HEPA Filter by protecting it.
  • The True HEPA Filter traps tiny particles such as mold spores, tiny dust particles, parts of smoke, and allergens such as pollen, dander, and mites. This stops germs in their tracks, decreases airborne allergens, and prevents the development or worsening of asthma or other breathing conditions.
  • The Activated Carbon Filter purifies household odors. Lingering smells from cooking, pets, or smoke will dissipate so you can always inhale fresh air.
