We all spend a lot of time indoors, either in our office or at home. Pollutants, pollen and pet dander can be worse inside some homes than out. For those who suffer from allergies, that can mean feeling miserable during seasons with less pollen, but fewer hours to spend outdoors.

Then, there are those odors we simply can’t live with. Whether it’s cooking smells, cigarette smoke, or other aromatic offenders, we want our air to smell fresh, clean and healthy. The best air purifier can effectively create that environment.

True HEPA air purifiers address these issues. When shopping, remember that you’ll want to budget for replacement filters, in addition to the initial cost of the air purifier. Some have washable pre-filters, which help extend the life of your True HEPA filter.

A few of these air cleaners kill viruses, mold spores, and germs, and many create just enough white noise to guarantee you a peaceful night’s sleep. They all make great gift ideas for someone you love, like your parents. If you’re ready to start breathing easier, check out our guide to the best air purifiers.

Our Unbiased Reviews
  1. 1. EDITOR’S CHOICE: IQAir HealthPro Plus Air Purifier

    • Filters out ultrafine particles
    • Removes most airborne pathogens, including Covid
    • Helps reduce dust, dander, mold and other allergens
    • Replacement filters can be expensive
    • Doesn't have WiFi or Alexa
    • Only comes in one color

    What’s the main difference between the IQAir HealthPro Plus and other air purifiers? It filters particles down to 0.003 microns in size. That’s 100 times smaller than 0.3 microns, which is typical for most air filters. As a result, you’ll inhale fewer potentially irritating or harmful particles, including ultrafine pollution particles. The filtration system has been independently tested and verified by a third-party lab for peace of mind. If you don’t mind splurging, the HealthPro Plus is our ultimate pick to keep your home air cleaner and safer.

    This award-winning air filter has four advanced filtration technologies. It includes a HyperHEPA filter that captures up to 99.5% of ultrafine particles. You’ll have extra protection against airborne pathogens, including Covid, MRSA, and various other bacteria and viruses. The particles are removed from the air then trapped in the filter materials so they can’t harm you or your family.

    Besides viruses and bacteria, this Swiss-made purifier reduces mold, pet dander, dust, and various allergens and asthma triggers. It also keeps your home smelling fresh thanks to a combination filter with activated carbon. Considering that most Americans spend around 90% of their time indoors, where pollutants can be up to 5x greater than outside, it’s a solid long-term investment for your health.

    Another feature that we love is that each filter is individually tested to ensure it’s delivering at least 99.97% cleaner air or better. And if not? It doesn’t get shipped. A 10-year limited warranty provides peace of mind.

  2. 2. RUNNER UP: LEVOIT Air Purifier

    • Can turn off display lights at night
    • Super-quiet night mode won't disturb your sleep
    • Great for smoke, toxins, pet dander, pollen and more

It’s much more affordable and can provide lasting relief from allergy and asthma symptoms. As someone with allergies and asthma, my symptoms have been noticeably better since I purchased my LEVOIT purifier two years ago. You can’t beat the overall value.

It features vortex air technology and 360° intake and purifies air in spaces up to 547 square feet. It takes just 30 minutes to remove impurities in larger rooms and 12 minutes in rooms up to 219 sq. ft. Whether it’s in a bedroom, dining room, living room or a study, you’ll have cleaner air in minutes.

    On the inside, a True HEPA filter captures 99.7% of airborne particles down to 0.3 microns in size. This includes dust, smoke, pollen and odor. Depending on your specific needs, there’s a smoke remover filter for smoke and wildfires and a toxin-absorbing filter to get rid of smog, VOCs and other toxins. If you’re allergic to pet dander, the pet allergy filter is for you.

    Day or night, you can run the LEVOIT purifier. Its near-silent operation at 24dB on Sleep Mode ensures everyone gets a good night’s sleep. You can also turn off the display light, which is a feature even some of the most expensive purifiers often lack.

    This model doesn’t have WiFi or Alexa, which helps keep the cost down. If you’re looking for those features or just want a purifier that will clean air in spaces up to 1,000 sq. ft., check out the LEVOIT Air Purifier with WiFi for Large Rooms.

  3. 3. Best Value: BLUEAIR Blue 211+ Air Purifier

Some of the most common causes include forest and grass fires as well as burning wood and heating oil.

    On the topic of filters, this one has a washable pre-filter to trap and remove large particles. The smaller particles are then removed by the main filter. Finally, the activated carbon layer captures odor-causing particles so your home won’t smell like a wet dog or last night’s fried fish dinner.

  8. 8. BISSELL air320 Smart Air Purifier

    • PM 2.5 particle sensor monitors help detect smoke particles

    • Can't be controlled with a smartphone

But it’s equally functional with a three-stage filtration system that captures everything from food odors to pet dander for a cleaner, healthier home.

    The secret to the BISSELL air320’s success is its three-stage filtration system. Large particles such as fibers, pet fur, hair and lint are captured in the pre-filter. Smaller bits such as pollen, dust and dander are captured in the main HEPA filter. The third filter is made with carbon and it reduces bad smells from gases, volatile organic compounds (VOCs) and pet and cooking odors.

    For added peace of mind, there’s color-coded air quality feedback. It signals when the air quality is good, moderate or poor, and adjusts the fan speed accordingly. If there’s cigarette smoke or even smoke from nearby wildfires, you’ll know if PM 2.5 particles are in the air you’re breathing. These tiny particles can get trapped in your respiratory system and lungs, potentially leading to breathing issues.

    Equipped with five speed settings, the lowest one can be library-quiet to avoid disturbing you and your family. A filter change indicator lets you know when it’s time to replace the filter. However, BISSELL suggests replacing your filters every six months for peak performance.

Is It Worth Getting an Air Purifier?

Let's cut to the chase so you can decide whether an air purifier is right for you.

After all, most will set you back a few hundred bucks. And that price doesn't even include the replacement filters, which can also be costly.

As we examined the world of air purifiers, ionizers, True HEPA, and other tech innovations that might address stinky and stale smell issues, we were surprised to discover that, after your initial cash outlay for many of these devices, you'll also need to budget for replacement filters, which aren't cheap.

Some purifiers actually have washable filters, totally a plus, while a couple of the devices we reviewed are actually filterless air purifiers.

Despite the initial investment, the long-term relief from troublesome respiratory symptoms, including sneezing and coughing caused by airborne pathogens, can be well worth it.

Do Air Purifiers Filter COVID?

Probably the most surprising thing we discovered when writing this article is that many air cleaners claim to kill viruses from the flu and measles, to MRSA, Strep, COVID, and the common cold. That alone makes them a worthwhile investment compared to spending days in bed feeling terrible.

However, an air purifier alone might not offer enough protection against highly transmissible viruses.

As with COVID, for example, the CDC strongly suggests ventilating with clean outdoor air whenever possible. But if that's not an option, a portable air cleaner is a good solution for a single room or area.

Which Air Purifier Should I Get for Allergies and Asthma?

When your allergy and asthma symptoms flare up, you'll quickly look for lasting relief. 

Air purifiers can remove airborne irritants in just 5 to 15 minutes, so you can soon breathe easier. 

As an added bonus, many of them create just enough pleasant white noise to guarantee you a peaceful night's sleep, in addition to clearer sinuses and waking up to less puffy, scratchy eyes. You'll feel better, and look better too.   

Some of our favorites include this Shark purifier with a True HEPA filter and the Blueair Protect 7470i.

What’s the Best Air Purifier for Pets?

As much as we love our furry friends, they can trigger allergy and asthma symptoms. If you share your home with pets such as cats, dogs, hamsters or birds, chances are the air you're breathing is less than clean.

The good news is that the right air purifier can reduce dust, dander, pollen and other allergens commonly associated with animals. 

Some of the best air purifiers for pets that we've tried include the IQAir HealthPro Plus, which traps tiny particles down to 0.003 microns, and the more affordable LEVOIT purifier.

And if you really want a clean house, check out our best automatic-empty robot vacuums that will remove pet hair, dander and dust from hard floors and carpets.

Which Is the Best Air Purifier for Smoke?

Wildfires and smoke events can occur without much warning, which is why it's a good idea to be prepared ahead of time. Once the fine particulate matter gets into the air, it can quickly enter your respiratory tract.

This particulate matter is called PM2.5, and it's as bad as smoking 155 cigarettes every year. A proper purifier can remove these particles from the air so you and your family can breathe easier.

The California Air Resources Board lists thousands of brands and models they recommend for filtering harmful particles from forest and grass fires.

Several of these models are on our list, including the Alen BreatheSmart purifier, Levoit air purifier, Rabbit Air and more. You can search the entries to find out if your preferred model is included.

Are HEPA Air Purifiers Better?

HEPA filters are highly effective at trapping airborne particles such as pollen, pet dander, dust and smoke. Many purifiers have HEPA filters, but you'll want to make sure the one you're considering is a True HEPA filter.

According to BannerHealth, it's the most effective type at removing ultra-fine particles that can worsen allergy and asthma symptoms. Avoid machines with a HEPA-like filter, which may not offer the full protection of a HEPA filter.
