6 Best Air Purifier for Wildfire Smoke

A blazing wildfire can travel at a terrifying speed for miles, and even if it doesn’t get too close to your neighborhood, strong winds can carry the smoke along with its harmful particles into your home. Wildfire smoke can have a drastic effect on the air quality inside, not to mention the smell that lingers around your home and sticks to your clothes, furniture, hair, and even your pets.

The amount of smoke wildfires cause is immense and can have a damaging effect on your health if not managed properly. It doesn’t only harm people suffering from respiratory diseases; long exposure to smoke is bad for everyone. [1]

If you’re in an area affected by wildfires, you may be familiar with: [2]

  • Stinging eyes
  • Persistent cough 
  • Chest pains
  • Headaches

The good news is, you don’t need to let wildfire smoke take over your life. By introducing the right air purifier with a HEPA + Carbon air filter into your home, you can eliminate many of these concerns. 

Carbon filters work by using activated charcoal to trap odors through a process called absorption. This means the smoke molecules attach to the outside of the filter instead of being soaked into it (absorption) eradicating them from the air in your home. [3]

As wildfires have been so prevalent again in the past year, air purifiers have become a much-needed item for households, but there are a few factors to consider before deciding on the right one.

Things you need to think about:

  • The type of filters it uses
  • How bad the smoke is affecting you and your family
  • The size of your room
  • Your budget

To help you find the right air purifier to match your needs, our research looked at:

1. Which filters are most effective for Wildfire Smoke? We decided only to recommend units that used pure or H13 HEPA and activated charcoal for those looking for air purifiers for wildfire smoke.

2. Consumer reports analysis. We evaluated the experience of users dealing with wildfire smoke as an issue to decide with different models of air purifiers work best.

Next, we will dig into the detailed review of our recommended units that we think are best for dealing with wildfire smoke in the home.

1. Winix 5300-2

Winix 5300-2 Air Purifier with True HEPA, PlasmaWave and Odor Reducing Carbon Filter,Gray

The Winix 5300-2 is a sleek black air purifier perfect for a modern household. It is ideal for rooms up to 360 sq.ft. We found this model to be exceptionally good value for money. Coming in at under $200, you’ll be hard-pressed to find another purifier with the same functionality as this at that price.

The 5300-2 uses a four-stage filtration system that includes a washable pre-filter, HEPA filter, and of course an activated carbon filter that focuses on reducing the smoke from wildfires and VOCs (Volatile Organic Compounds). Winix does say you’ll need to change the filter every three months, but by making full use of the washable pre-filter and keeping them clean, you should get a bit more life out of each one.

One of the best things about this air purifier is its smart sensors. These monitor the air quality and will adjust its fan speed accordingly, which is perfect as smoke particles can get into your home undetected by human smell. The LED light on the front panel will also give you an easy-to-read indicator so you know the state of your air quality in real-time. 

What we love:

A big name in the air purifier game, the Classic 605 from Blueair is one of the larger units on our list and by far the most expensive. But with this purifier, you’re paying for a highly-effective product for larger rooms and homes. If your surrounding area is on the front line of wildfire smoke, the 605 will clear rooms up to 775 sq.ft., which is perfect for open-floor plan and studio areas. 

The filter uses electrostatic technology, which charges the smoke particles that pass through it, making 99.97% of them stick to the filter instead of just catching them. By combining the HEPA filter with its activated carbon filter, those nasty odors are removed from your room at an impressive 500 CADR rating for smoke. The 605 also boasts that when running at lower speeds, it uses less energy than a lightbulb. 

A great feature that comes with this air purifier is the smart control app. You can connect your smartphone to the 605 and control the settings from anywhere. The app also gives you information about the air quality both inside and outside your home, allowing you to adjust the purifier accordingly. This technology is perfect for making sure pets are safe when you’re at work and allows you to come home to an already smoke-free environment.

Using HEPA technology to capture small particles and take care of any ash that invades your home, it also contains a large 1.15lb activated carbon filter.

The good news is that it will tell you when it needs to be changed and the filters are easy to come by.

The 5900 is easy to use with its intuitive controls and fan speed indicators. It may not be the quietest of the purifiers on our list at high speeds, but it will make your home a safer place to be when confronted with smoke caused by wildfire.

Coway Airmega 400 Smart Air Purifier with 1,560 sq. ft. Coverage

The Airmega 400S from Conway is a beast of an air purifier. This is your best choice for large rooms as it’s designed to cover an area of up to 1560 sq.ft. The price is a little steep but this model sells out quickly for a reason. It is quite a large unit, which you can tell by the design. It isn’t there to just look good, it’s there to work.

The 400S uses two pre-filters and two HEPA filters (one left, one right) packed with activated carbon to remove all the particles wildfire smoke intrudes our homes with. The pre-filters are washable, giving the “Max2” filters more life to work at their full potential, and with five different fan settings cleaning a large area two times an hour, they really are grinding.

On this sophisticated machine, the ‘S’ stands for smart. Not only will it adjust its fan speed based on air quality conditions automatically, but you can change any of the settings from your smartphone. When the unit is connected to Wi-Fi, it will send indoor/outdoor air quality reports to your app and will even send you a notification if there’s a spike, like winds carrying smoke in your home’s direction.

What we love:

6. PARTU BS-08

PARTU HEPA Air Purifier - Smoke Air Purifiers for Home with Fragrance Sponge - 100% Ozone Free, Lock Set, Eliminates Smoke, Dust, Pollen, Pet Dander, (Available for California)

Our final selection may be the smallest unit, but don’t judge it on its size. At under $100, the BS-08 from Partu is your option if you’re not wanting to break the bank or if you’re only looking at an air purifier for a small room. This little black bullet won’t be getting in anyone’s way and features a touch screen panel as well as color-changing lights to fit your mood.

On the inside, the BS-08 houses a three-in-one filter made up of the essential pre-filter, HEPA filter, and the activated carbon filter to eliminate 99.97% of air contaminants for rooms up to 160 sq.ft. It won’t be very effective in a large room or in an area heavily affected by wildfire smoke but will do perfectly in a small home office as an extra precaution.

The Partu has three fan speed settings, a filter indicator, and an Anion mode. This sends six million negatively charged ions into the air to attract unwanted particles. It may not have all the bells and whistles from the others on our list but it still gets the smaller job done.

Frequently Asked Questions

Do air purifiers help with wildfire smoke?

Yes, they do. By introducing the right air purifier into your home that will recirculate the air, you can reduce the number of smoke particles, clear any unwanted airborne dust and ash, and combat the nasty odor wildfire smoke leaves behind. [4]

How well do air purifiers work for wildfire smoke?

Air purifiers can be extremely effective for removing wildfire smoke from the home. You can maximize their effectiveness by having the unit on continuously or as often as possible on the correct setting for the situation. You can also aid the purifier by keeping windows and doors closed and placing them in the worst affected areas. [5]

What features and considerations are important when buying an air purifier for wildfire smoke?

There are a few considerations you need to make before you jump in and buy. 

  1. Look at the size of your home and find which purifier is best suited to the area it will be working in.
  2. Focus on the type of filter it uses. HEPA filters are scientifically proven by NASA to be the most effective all-round, but in the case of wildfire smoke, you want a purifier with an activated carbon filter to deal with the odor. The basic rule here is, the more carbon it has, the more effective it will be. 
  3. Assess your budget. Don’t go blowing your kids’ college fund on a huge unit if you live in a small apartment. In the same breath, don’t buy a $90 one for a big room as it won’t do the job properly.
  4. Whatever you do, don’t buy one that produces what they call ‘Ozone’. These emit harmful chemicals that can do more harm than good.

Which Air Purifier is Best for Wildfire Smoke in Your Home?

Your home is your refuge, a place where you’re safe and comfortable and nothing should compromise that. If you live in an area affected by wildfire smoke, you’ll know all too well the dangers it can cause to your health and the effect it has on your home. 

We made this list because we realize the different needs people have and the importance of buying the right purifier to meet those needs. Biggest is not always best. By identifying those needs and doing tons of research, we put together this solid variety of air purifiers.

Which Air Purifier is best for you?

  • Mid-range – We recommend the Winix 5300-2 for its smart sensors and value for money.
  • Larger rooms – For a top-end purifier, we recommend the Conway Airmega 400s with its duel filters and smart technology.
