Do Air Purifiers Help with Allergies?

We spend a lot of time inside. In fact, the Environmental Protection Agency (EPA) has estimated being indoors accounts for 90% of our days. Having said that, the EPA also says your indoor air can be three to five times worse than outside.

That’s because our residences are firmly sealed to enhance energy efficiency. While this is good for your energy costs, it’s not so great if you’re among the 40% of the population with respiratory allergies.

When outside ventilation is insufficient, pollutants like dust and volatile organic compounds (VOCs) may get captured. As a consequence, these pollutants may worsen your allergies.

You can improve your indoor air quality with fresh air and usual dusting and vacuuming. But if you’re still having issues with symptoms while you’re at your house, an air purifier could be able to provide assistance.

While it can’t eliminate pollutants that have landed on your couch or flooring, it may help purify the air moving across your house.

And air purification has also been scientifically confirmed to help lower some allergic symptoms, according to the American College of Allergy, Asthma and Immunology. It can also be helpful if you or a family member has lung issues, like emphysema or COPD.

There are two models, a portable air purifier or a whole-home air purifier. We’ll go over the differences so you can figure out what’s correct for your house.

Whole-House Air Purifier vs. Portable Air Purifiers

A portable air purifier is for one room. A whole-house air purifier works with your heating and cooling system to purify your full residence. Some types can work by themselves when your HVAC system isn’t running.

What’s the Best Air Purifier for Allergies?

Go after an option with a High Efficiency Particulate Air (HEPA) filter. HEPA filters are installed in hospitals and deliver the most comprehensive filtration you can buy, as they eliminate 99.97% of particles in the air.

HEPA filters are even more powerful when used with an ultraviolet (UV) germicidal light. This powerful blend can wipe out dust, dander, pollen and mold, all of which are common allergens. For the ultimate in air purification, consider a system that also has a carbon-based filter to decrease household smells.

Avoid getting an air purifier that creates ozone, which is the primary ingredient in smog. The EPA cautions ozone may irritate respiratory symptoms, even when released at minor concentrations.

The Allergy and Asthma Foundation of America has created a checklist of questions to consider when purchasing an air purifier.

  • What can this purifier take out from the air? What doesn’t it extract?
  • What’s its clean air delivery rate? (A bigger figure means air will be cleaned more rapidly.)
  • How often does the filter or UV bulb need to be switched? Can I finish that on my own?
  • How much do new filters or bulbs cost?

How to Reduce Seasonal Allergy Symptoms

Want to get the most excellent results from your new air purification system? The Mayo Clinic suggests completing other measures to limit your exposure to problems that can cause seasonal allergies.

  1. Stay indoors and keep windows and doors sealed when pollen counts are elevated.
  2. Have other family members cut the lawn or pull weeds, since these tasks can worsen symptoms. If you have to do these jobs yourself, consider wearing a pollen mask. You should also bathe without delay and change your clothes once you’re finished.
  3. Avoid drying laundry outside your home.
  4. Turn on your air conditioner while at home or while in the car. Consider adding a high-efficiency air filter in your house’s HVAC system.
  5. Balance your residence’s humidity saturation with a whole-house dehumidifier.
  6. Hardwood, tile or linoleum are the ideal flooring materials for reducing indoor allergens. If your residence has carpet, install a HEPA filter on your vacuum cleaner.
