Air Purifiers : Best Buying Guide 2020

Air Purifiers are a necessity to safeguard the health of the family members as long-term exposure to high particle levels is linked to bronchitis, reduced lung function, and premature death.

Pollutants such as smoke from tobacco, wood burning, and cooking; gases from cleaning products and building materials; dust mites; mold; and pet dander all contribute to an unhealthy indoor environment that have ill effects on human health.

Fine particles 10 micrometers in diameter or smaller, including those found in dust and smoke, are especially a concern because they can find their way deep into the lungs. Breathing in particles for just hours or days is enough to aggravate lungs and cause asthma attacks, and has been linked to heart attacks in people with heart disease.

Volatile organic compounds are released into the air from adhesives, paints, and cleaning products can cause nose, throat, and eye irritation; headaches; nausea; and damage to the liver, kidney, and nervous system. Some gases, such as radon, cause lung cancer and death.

Best Air Purifier for Your Home

The best ways to improve indoor air are to remove the pollutant sources and ventilate with clean outdoor air. Portable air purifiers can help when those methods are insufficient or not possible. Also known as air sanitizers, air purifiers are designed to filter the air in a single room, not the entire house, like an HVAC system does. And while they do help to reduce indoor pollution, there are limits to what they can do.

What Air Purifiers Do Well

The air purifiers that do well in our tests are proved in our labs to be good at filtering dust, smoke, and pollen from the air. Multiple studies of portable air purifiers show that using HEPA filters results in reductions of 50 percent or higher in particulate matter.

What Air Purifiers Don’t Do

An air purifier can remove allergens only while they’re floating in the air. Larger, heavier allergens, such as mites, mold, and pollen, settle to the ground so quickly that the air purifier can’t capture them in time.

What We Don’t Yet Know

Radon is another blind spot for air purifiers and other air cleaners as the studies are inconclusive on air purifiers’ ability to tackle this dangerous gas. And in fact, there is insufficient research on air purifiers that address gaseous pollutants as a group, so it’s unclear how effective air purifiers are.

Types of Air Purifiers

There are several technologies air purifiers employ for tackling indoor pollution. Some work better than others. Some can actually be bad for your health.

Mechanical filtersAir purifiers with pleated filters use fans to force air through a dense web of fine fibers that traps particles. Filters with very fine mesh are HEPA filters—those certified to collect 99.97 percent of particles of a certain size (0.3 microns in diameter—smoke and paint pigments, for example).
HEPA filtersHEPA can remove larger particles, too, including dust, pollen, and some mold spores while they’re suspended in the air. Note that some filters labeled “HEPA-type” or “HEPA-like” have not been certified to meet the requirements of a true HEPA filter but may still perform adequately in our tests.
Activated carbon filtersRather than catch particles like mechanical filters, sorbent filters use activated carbon that can adsorb some odor-causing molecules from the air. They may also tackle some gases, but they’re not particularly effective against formaldehyde, ammonia, or nitrogen oxide. Because they don’t combat particles, many air purifiers will include both an activated carbon filter and a pleated filter for catching particles.
Ozone generatorsThese machines produce ozone, a molecule that can react with certain pollutants to alter their chemical composition. Ozone has been linked to decreases in lung function and increased risks of throat irritation, coughing, chest pain, and lung tissue inflammation. Ozone might also worsen asthma, emphysema, and bronchitis.
Electronic air purifiersElectrostatic precipitators and ionizers charge particles in the air, so they stick to plates on the machine or to nearby surfaces by a magnetic-like attraction.
Ultraviolet germicidal irradiation (UVGI)Manufacturers claim their air purifiers kill airborne viruses, bacteria, and fungal spores with UV lamps but still some bacteria and mold spores are resistant to UV radiation. To work, the UV light must be powerful enough and the exposure must last long enough—minutes to hours rather than the few seconds typical of most portable UVGI air purifiers—to be effective.

What to Consider While Shopping for an Air Purifier

Cost of replacement filtersAs a general rule, you should replace filters (or clean those that can be cleaned) every six to 12 months for pleated filters and every three months for activated carbon filters.
CertificationsAir purifiers must run around-the-clock to be effective, and you should factor in the energy cost when you shop. Energy Star certified purifiers are 40 percent more energy-efficient than standard models.
Room sizeMost of the models that are suitable for large rooms (350 square feet and up) still work well at lower (quieter) speeds, which is nice for when you’re watching TV or sleeping.
NoiseAs machines should always be running, so ideally they should also be quiet. Run the unit on the high setting when you’re not in the room and turn it down to low when you’re nearby. Or buy an air purifier certified for a larger area so that even at a low speed, it filters more air.

Air Purifier Features to Look For

Below are several features worth looking for on your next air purifier.

Washable Prefilters
The reusable filters collect large particles before they reach the primary filter, potentially extending its life and saving you money on filters.

Air Purifier Features to Avoid

An air purifier label that states the model is ARB certified.An air purifier’s activated carbon filter.An air purifier’s UV button that activates its UV lamp.

Anything That Emits Ozone. If a unit has an ionizer (which attracts particles via an effect like static electricity), it may produce ozone.

How to Get the Most Out of Your Air Purifiers

Clean or replace filters regularlyAs a general rule, you should replace them (or clean those that can be vacuumed) every six to 12 months for pleated filters and every three months for carbon filters.
Place it wiselyIf you have just one unit, place it in the room where you spend the most time. For most people, that’s the bedroom. These machines can be heavy and clunky to move around, so if you want an air purifier in multiple rooms, you may want to buy a unit for each room.
No ObstructionPlace the air purifier at a spot where airflow is not obstructed —away from curtains.
Keep your purifier running 24/7While it’s in use, keep doors and windows closed. Running the unit on the high when nobody in the room and turning it down to low when you’re nearby. While it’s in use, keep doors and windows closed. Running the unit on the high when nobody in the room and turning it down to low when you’re nearby.
Vacuum regularlyAs no air purifiers can remove the larger allergens—dust mites and pet hair, you must use HEPA-certified filtration vacuum a once or twice a week to clean floors and furniture.
VentilateOpen windows to let in clean and dry air from outdoor. If pollen or related allergies does not allow you to open windows, run air conditioner or forced-air cooling system with air filter.
Some more Precautions* Use an exhaust fan for kitchen, bathrooms and laundry rooms.
* Do not smoke indoors and also do not burn candles and wood fires.
* Reduce chemical and heavy cleaning products, and don’t store paint, glues, or insecticides near your living quarters.
