While most people are aware of pollutants floating around outside, it may come as a surprise to learn that people with allergies may be even more vulnerable indoors. The prolonged amount of time that we are all spending inside might have you looking for another solution to help clean and filter the air in your home, the one thing that disinfecting wipes can't do.
“The Environmental Protection Agency has reported that indoor air — where we spend more than three-quarters of our days — is often even more polluted versus outdoor air,” said Dr. Clifford Bassett, founder and medical director of Allergy and Asthma Care of New York and author of The New Allergy Solution.
For clean air, eliminate sources of pollution, like cigarette smoke, air fresheners, wood-burning fireplaces and harsh cleaning chemicals, noted Dr. Denitza Blagev, a pulmonologist at Intermountain Medical Center in Salt Lake City, Utah.
People with allergies should decrease exposure to triggers (use allergy-proof bedding for dust mites, wear wraparound sunglasses to block outside pollen) and work with a doctor on a medication strategy, said Bassett.
An indoor air filter or purifier can also be effective in removing harmful pollutants, said Blagev.
Standalone units that are designed to filter a designated area should be placed in rooms where you spend most of your time, like the bedroom, Blagev added. Just remember to change the filter regularly based on the manufacturer’s suggestion.
With so many options out there, it can be tough to find an air filter that's both effective and safe. Here are a few suggestions from doctors that pass the test:
This is a splurge, but Rabbit Air purifiers come with some serious perks. This one can purify a room up to 700 square feet. Bassett said he likes this brand because it makes customizable filters that address odors, toxins or pet allergens. It can also be mounted on a wall. And, it looks attractive.
This is another option that’s been certified “asthma and allergy-friendly” by the AAFA. It features a HEPA and carbon filter that traps particles as small as 0.3 microns. “The most harmful particulates are the smallest, or less than 2.5 microns in size,” said Blagev.
Some air purifiers intentionally produce ozone (it's usually noted in the advertisements). But, these can be dangerous for your health. “Ozone is a colorless, odorless gas that contributes to an increased risk of asthma and other respiratory symptoms,” said Blagev. Look for air purifiers that don’t generate ozone. This model is certified by the California Air Resources Board since it meets the limit on ozone emissions.
HEPA stands for high-efficiency particle air. A HEPA filter is designed to remove 99.97% of airborne particles (measuring .3 micrometers or greater) in diameter passing through it.
“Room air cleaners with a HEPA filter are the best choice,” said Dr. James L. Sublett, chief medical officer at Family Allergy and Asthma in Louisville, Kentucky. One brand he likes is Honeywell. Also, consider the size of the room for the best efficiency. This specific model helps clean rooms up to 155 square feet.
The Allergy and Asthma Foundation of America certifies household products as "asthma and allergy-friendly,” so it’s a great resource to help narrow down the best air purifiers, said Bassett. The AeraMax 100 has been certified by the foundation. It's a portable air cleaner that removes 99.97% of airborne particles. It best fits rooms that are up to 200 square feet.
“I am a fan of attempting to get an indoor clean air boost with various NASA-studied plants that have been found to potentially scrub and purify indoor air of common pollutants,” said Bassett. Peace Lily and English Ivy are two good options.
