Whether you suffer from allergies or simply reside in a particularly polluted city, purifying the air in your home can make a big difference in how you feel each day. Due to the coronavirus pandemic, most of us probably spend even more time at home than before — making it extremely important to disinfect and keep your living space as clean as possible.

“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.

The prolonged amount of time that we are all spending inside lately might have you looking for another solution to help filter the air in your home, but luckily you can purify the air throughout your entire home with just a few simple steps.

To help break it all down with some tips and tricks, “HouseSmarts” host Lou Manfredini stopped by Hoda & Jenna. From filters to air purifiers, Manfredini shares how you can keep the air in your home clean to breathe easy no matter the season.

How to purify the air in your home

Whole house air purifiers are one way to help reduce pollution in the air in your home, which are different than whole house air humidifiers.

"These are separate appliances that you can place in a basement in a family room on an entire first floor," Manfredini says, "and it will capture all the air in those rooms and filter it through a highly refined filtering system. Many use HEPA filtration."

Another way to help improve the air quality in your home is by replacing the furnace filters in your home. You don't have to opt for pricey filters, but it's best to choose a filter that is pleated rather than one made from spun fiberglass, Manfredini said. To clean the vents throughout your home, such as floor and wall vents, you're going to want to use a vacuum and a dusting rag in order to remove debris.

Calling in the professionals to clean and seal your ductwork is another option that will help keep the air in your home clean, as it prevents dust from accumulating, making your furnace more efficient.

Air purifiers as seen on TODAY

Blueair Blue Pure 211+ Auto

Manfredini called out this air purifier from Blueair for being "very quiet, very efficient." He also notes that since it features an LED indicator, you can monitor the quality of the air while the filter indicator lets you know when it needs to be replaced. It's designed for large rooms and, despite the large capacity, operates on an ultra-quiet filter using HEPASilent technology.

Coway AirMega 400S

This larger unit is meant to be run continuously in large rooms. It operates on five fan modes and can connect to your smartphone so that you can monitor air quality levels, know when to change the filter, set filtering schedules and more. The HEPA filter captures 99.97% of pollutants and is also washable.

Expert-recommended air purifiers

Dr. Denitza Blagev, a pulmonologist at Intermountain Medical Center in Salt Lake City, Utah, says that an indoor air filter or purifier can also be effective in removing harmful pollutants.

Standalone units that are designed to filter a designated area should be placed in rooms where you spend most of your time, and Blagev notes that it's important 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:

Rabbit Air MinusA2 Ultra Quiet HEPA Air Purifier

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.

Dyson Pure Cool Link Air Purifier

This option has been certified “asthma and allergy-friendly” by the Asthma and Allergy Foundation of America (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,” Blagev said.

Honeywell True HEPA Allergen Remover

HEPA stands for high-efficiency particle air. A HEPA filter is designed to remove 99.97% of airborne particles (measuring 0.3 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.

It's important to consider the size of the room when choosing the best filter for your home. Sublett recommends Honeywell's line of filters, and this specific model helps clean rooms up to 155 square feet.

AeraMax 100 Air Purifier

The AAFA certifies household products as "asthma and allergy-friendly,” so it’s a great resource to help narrow down the best air purifiers, Bassett told us. 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.

Peace Lily Plant

“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,” Bassett said. Peace lily and English Ivy are two good options.
