The air you breathe may be affecting you in ways you are not even aware of. Air pollutants such as dust, pollen, smoke and mold can trigger allergies and irritate you. Chemicals, perfumes, paint, and carpeting can release noxious odors and harmful particulates. Not to mention that the 2020 pandemic has made us all more conscious of what we breathe in and out.

Choosing the best air purifier for the home or office, including a home office, can really improve the quality of life and enhance productivity. The air purifiers in our list can help you breathe easier. The key is identifying the specific particulates you are concerned about and ensuring the air purifier you buy can filter them. You also must choose the right size purifier for your space. Whether you want to clean the air in a small office for the benefit of employees and customers — or make your home or home office more enjoyable — an air purifier can deliver peace of mind and comfort.

How to Choose the Best Air Purifier

The best air purifiers offer the best combination of filtering capability, air circulation capacity, looks, low noise, affordable cost, and easy maintenance. Consider these specific factors:

  • Size: Consider the size of room the air purifier is meant for. An undersized product won’t do the job. Some models are small enough to use in a home office setting — say a spare bedroom. Other air purifiers are big enough for larger spaces like an open office. Measure the size of the room for the air you want to clean. Then look for specific square footage in product descriptions as you shop for the best air purifier.
  • Price: The best air purifiers range in price from about $100 up to thousands of dollars. Budget conscious buyers usually can find something between $100 to $600, depending on size and features.
  • Particulates: The best air purifiers can clean many particulates from your office environment, but different models actually have quite a bit of variance. If there are specific airborne particles or particulates you want to filter out, check product specifications carefully or ask the manufacturer. Be especially careful about claims to remove specific particulates such as mold spores, virus airborne particles, or dust, pollen and smoke.
  • True HEPA filter: With a True HEPA filter, a purifier will remove 99.97% of particulates measuring 0.3-micron in diameter. Some air purifiers do not have true HEPA filters, but may offer a higher level of HEPA. Others have what they call a HEPA type filter.
  • Other filters: Different filters catch different things. The best air purifiers include multiple types of filters, including carbon activated filters, true HEPA, and outer filters to capture hair and dust bunnies.
  • CADR rating: The CADR (clean-air delivery rate) rating indicates the rate in which it can clean out smoke, pollen, and dust. And there is a number for each particulate. You want higher numbers because it means it filters more air in cubic feet per minute (CFM). CADR gives you a way to pick out the best air purifier by comparing different brands and models.
  • Noise: A loud air purifier can be annoying and interfere with work. Compare decibel levels at the fan speed you are most likely to use. For comparison, the sound of rustling leaves is about 20 decibels, while a standard conversation at home is about 50 decibels. Search for the words “quiet” or “ultra quiet” in descriptions of air purifier products.
  • Placement: Also consider where the air purifier will be placed. If placed on your desk the noise level matters a lot more than if a unit is off in a corner. How big is the unit? That also determines placement. Some air purifiers are just too big to go on a tabletop or fit into a small workspace or cubicle.
  • Style and design: The best air purifiers don’t just work great, they look great. Consider how the purifier looks. It makes a difference.
  • Odors: Many air purifiers do not do a good job with ordinary odors. It depends on the type of odor, and the type of filters. What’s the odor’s underlying cause? Removing the cause can help remove the odor – but if you don’t get rid of the cause such as mildew or pet stains, the odor will be persistent. Purifiers with an activated carbon filter generally do the best job cleaning the most odors, but read descriptions carefully.
  • Changing filters and long-term costs: Air purifiers require regular changes and/or cleaning of filters. HEPA filters, in particular, must be changed at recommended intervals if you expect to get the benefits. Filters add to the long-term cost, so consider the price of filters when comparing costs of the best air purifiers.
  • AHAM Verified mark: The Association of Home Appliance Manufacturers tests and verifies products to ensure safety and efficacy. It does this for the EPA and its Energy Star program. The testing also includes the CADR rating.

Air Purifiers and Coronavirus

People want to know whether an air purifier can protect workers from COVID-19. The answer, according to experts at the Mayo Clinic, is that air purifiers with a HEPA filter can help by exchanging clean air — but by itself even the best air purifier is not enough protection against the virus.

“The more air exchanges and the cleaner the air, the lower the risk,” says Dr. Gregory Poland, a Mayo Clinic infectious diseases expert in a video statement on October 2, 2020. But he goes on to say, “By itself, it’s not satisfactory, so what we’re doing, as we’ve talked about over the months, is we’re layering protections. Let’s be sure the air in our home, if we’re having people to our home, is as safe as it can be. That means a HEPA (high-efficiency particulate air) filter.” The filter does not kill the virus, but rather it exchanges clean air more rapidly to get rid of the virus faster, he adds.

The Centers for Disease Control (CDC) also weighs in, “When used properly, air purifiers can help reduce airborne contaminants, including viruses, in a home or confined space.” But the CDC guidance goes on to say, “Running your HVAC system, using an air purifier or a portable air cleaner, and increasing ventilation are not enough to protect yourself and your family from COVID-19. Continue to follow other prevention guidelines.”

In summary, according to the experts, an air purifier with a HEPA filter can help clean and circulate air, but is not protection enough alone. Other protection techniques such as masks, social distancing, hand sanitizers, and more must be used — along with an air purifier with HEPA filter.

Editor’s note: We will continue to update this topic as the experts learn more and share additional guidance.

  1. I can attest that the Levoit Air Purifier is a good one because I own one of these. The model I have is not quite the same one as you have featured as your top pick, but it is similar in size and function. For those of you looking at getting one of these for your office or bedroom, they are definitely worth it and from an allergy perspective, they really help. As Michael points out, you do need to figure out the square footage of the office or room you are using it in to make sure it will be effective, otherwise, if you have a larger office you may need two of them or a larger unit.
