Air Purifier Buying Tips From The Experts

If you’re starting your search for the right air purifier for your space, begin with these expert tips to ensure you’re getting the best fit for your home:

  • Start with the HEPA filter. HEPA — or “high efficiency particulate air” — filters are the gold standard in air purifiers, but make sure you’re getting the real thing. “For HEPA, look for the label ‘True HEPA.’ This way we know it's effective at removing particulates like allergens and spores,” advises Corinne Segura, Building Biologist, My Chemical Free Home.
  • Consider the space. When it comes to room size, “manufacturers’ claimed room size is often overstated so when in doubt, always size up,” says David Bloom of Green Home Solutions.
  • Look beyond HEPA. Consider a “carbon filter to eliminate any odors — especially if you have pets. While the HEPA filter removes any nasty particles, an added carbon filter can help you keep your home smelling nice and fresh,” says Matt Clayton of PetHairPatrol.
  • Think about where it’s going. Since we spend so much time there, Clayton suggests an air purifier for bedrooms. “Studies have shown that the air quality in your bedroom affects your sleep. Using an air purifier during the night will help you sleep better and wake up rested.”
