LEVOIT Air Purifiers for Home
$499.99
We first purchased a LEVOIT air purifier for our home during the pandemic, and the brand continues to be our go-to for easy and effective safeguarding from allergens, smoke, odors and more.
We love this purifier’s very impressive three-stage filtration system, which can rid the air of heavy smoke and nasty odors in rooms up to a whopping 2,790 square feet in just an hour. If you really want to make sure that the air in your room is clean, the laser dust sensor detects PM1.0, PM2.5, and PM10 particulate matter sizes, which will not only allow the purifier to evaluate the air quality of the room, but change its fan speed to fit the situation. The device’s nifty sleep mode helps create a peaceful, soothing environment while keeping the air free of harmful particles.
In terms of filter replacement, there’s a washable pre-filter, but you should only need to change the other two every 6-8 months. However, you can monitor the filter’s life on the handy VeSync app, so you’ll never have to be left guessing as to when it’s time to replace it
BEST DESIGNED
Molekule Air Pro Air Purifier for Large Rooms
$1,014.99
This air purifier from Molekule boasts a smooth and portable design, with a built-in carrying strap. It’s also easy to use right out of the box, either by activating the touch-screen display or from your smartphone via Molekule’s iPhone and Android app.
By using a process known as PECO (Photo Electrochemical Oxidation), this purifier traps and breaks down all volatile organic compounds (VOCs); in other words, it literally replaces the air in the rooms up to 1,000 square feet, helping keep you safe from wildfire smoke and dust.
The brand says that smoke particles are trapped by the HEPA filter, and toxic gasses are quickly removed with activated carbon, while PECO provides another layer of protection by destroying the organic substances that are common in wildfire smoke. When set to Auto-Protect mode, the Air Pro will also automatically increase power when pollution levels rise. Because it can detect six pollutant types, you’ll also know in real-time how wildfire smoke might be impacting your indoor air quality.
Reviewers online say they’ve purchased the Air Pro when needing extra circulation (say, when deep cleaning a room, or working on a remodeling project) and when their homes are in the path of wildfire smoke.
BEST FEATURES
BLUEAIR Blue Pure 311i Max Air Purifier
$159.99 $229.99 30% off
Once you start looking at all of the capabilities and features, it’s easy to see why the Blueair Blue Pure 311i Max was selected as Amazon’s choice air purifier. In fact, the site says more than 6,000 people have purchased this unit in the last month alone.
It’s one of our favorite air purifiers too, and we use one in our bedroom and one at the office. Why? For starters, it promises to completely filter the air in large rooms every 12.5 minutes, targeting up to 99.97% of tiny airborne particles down to 0.1 microns from wildfire smoke as well as pollen, dust and pet dander. The dedicated carbon filter also traps household odors from smoking and cooking, too.
With a plethora of smart features you can also put the air purifier on a schedule, monitor air quality and more on the app, as well as turn it on with your voice through Alexa. While it’s powerful it doesn’t utilize a lot of energy — in fact, all three speed settings use less energy than the average light bulb; the filter itself is ENERGY Star certified, so you can sustainably purify your air.
BUDGET-FRIENDLY PICK
LEVOIT Air Purifier for Home
$99.99
If you’re looking for a more inexpensive option, we recommend this best-selling model from LEVOIT. Available for under $100, it’s a no-brainer to pick up to protect yourself from the lingering effects of wildfires and smoke.
What we like: it’s powerful enough to refresh the air five times per hour, though it’s smaller size lends itself best to working in rooms up to 219 square feet.
Our favorite quality of this purifier is its capability to support different filters; you also have the ability to choose the filter that best suits your situation. Whether you’re looking to combat wildfire smoke or rid the space of pesky allergens, you can ensure your needs will always be met. But don’t just take our word for it, head on over to Amazon and read any one of the more than 100,000 five-star reviews.

MOST EFFICIENT
Coway Airmega AP-1512HH True HEPA Purifier
$168.99 $229.99 27% off
Sleek and stylish, this top-rated Coway purifier looks as good as it cleans, and boy does it deliver some stellar purifying performance.
You’ll get the four-stage filtration process that Airmega line is known for, and this model’s filter can capture up to 99.97% of particles 0.3 microns in the air, including smoke, pollutants and other allergens. But the fourth filter is the key here, a vital ionizer which reduces ultra-fine particles in the air like viruses and bacteria. That’s a huge upgrade from your basic HEPA filter, but what’s an even bigger upgrade is it’s efficient operation.
Not only is the Airmega able to filter the air in a room up to a whopping 4.8 times per hour, it handles well even in larger rooms up to 874 square feet, refreshing the air twice per hour. By quickly removing the smoke particles that cause respiratory symptoms and odor, this makes it great for a main living room or a small apartment. An energy-saving air quality monitor also adjusts the fan speed to match the air quality in your room.
How Does An Air Purifier Work for Smoke?
The best air purifiers for smoke remove contaminants from the air through a circulating fan and one or more filters. The fan sucks up the air in the room the device is placed in, and pushes it through the filters, where all of the contaminants are removed and trapped. The purified air is then pushed back out into the room.
As we mentioned before, air purifiers with HEPA filters can help reduce particle concentrations by up to 85%, according to the EPA. This is because smoke particles (like from cigarettes) tend to be between 0.1 and 1.0 microns in size, but a True HEPA filter can remove 99.97% of particles up to 0.3 microns in size. One thing to consider, though, is that cigarette smoke can contain volatile organic compounds (VOCs) that a HEPA filter won’t work well for, which is where an activated carbon filter comes in. The more carbon in the filter, the more effective it will be against VOCs.
By investing in a solid air purifier, you can have peace of mind that the air you’re breathing while in your living space is clean. That said, these devices aren’t a be-all end-all solution to removing smoke and smog. Still, a good air purifier can definitely help keep you safe when implemented along with other safety precautions, such as sealing any openings, wearing face coverings (in cases of extreme smoke) and evacuating the premises if the smoke gets too close or dangerous.
How We Chose the Best Air Purifiers for Smoke and Smog
When we were evaluating potential air purifiers for smoke and smog, we considered the following criteria (and you should too).
Filter: The average air purifier isn’t equipped to handle the contaminants found in smog or cigarette smoke. We chose purifiers outfitted with a HEPA filter to effectively safeguard your space against these particles, as well as a carbon filter to ward off those pungent odors.
You’ll also want to take a look at how often your filter(s) need to be replaced (more smoke means a dirtier filter, quicker). This could be an important factor when assessing your decision if replacement filters are particularly costly.
Size: Bigger rooms and living spaces need a larger air purifier to work effectively, so we made sure these air purifiers could either handle big rooms (above 500 square feet) or had a high enough air turnover rate that they would remain effective no matter the space.
Noise: To make sure you’re getting the most out of your air purifier, you should be running it all day, every day. Because of this, you’re not going to want one that makes a lot of noise, especially if you’re someone who is still working from home or who is a light sleeper. We picked air purifiers with relatively silent operation (around 24dB, or “near silent), or at the very least have a “quiet” mode.
