Do you find yourself sniffling and sneezing when lounging around your house? Or maybe there’s always a lingering food odor floating around your kitchen? If so, it sounds like you need an air purifier!
Air purifiers do just what their name suggests—they help to clean and purify the air in your home. Poor indoor air quality can make you feel stuffy and uncomfortable, as there may be dust, pollen, pet dander, and other unsavory particles floating around. All of this can trigger allergies, asthma, and just make your home feel a bit stale.
Luckily, air purifiers are simple and easy to use. They use different cleaning mechanisms—such as HEPA and carbon-activated filters or even UV light—to capture or otherwise remove microscopic air pollutants, leaving your home fresher and cleaner than ever.
Here, a handful of the best air purifiers you can buy.
Best Overall: NOMA Medium Air Purifier with True HEPA Filter
This air purifier from NOMA has a HEPA filter—often viewed as one of the best options if you want to improve the air quality in your home. Why? HEPA filters remove 99.97 percent of allergens, dust, and pet dander, as they can capture particles as small as 0.3 microns in diameter.
This particular HEPA air purifier also uses negative ions to remove harmful particles from the air, and its Auto Purification setting automatically adjusts the inner fan speed when it senses air quality is low. Plus, the air quality indicator ring on the top of the unit changes color to let you know how clean—or dirty—your air is. Cool, right?
Best Budget: Bissell MyAir Personal Air Purifier
For an affordable air purifier that’s ideal for small spaces, you’ve got to go with the BISSELL MyAir Personal Air Purifier. This three-in-one device has a pre-filter, high-efficiency filter, and activated carbon filter, helping to rid your space of pollen, dust, dander, and even household odors.
Because it’s a “personal” air purifier, it’s best for small spaces—around 100 square feet—and its compact design is great for tucking into a discrete corner of the room. Plus, it’s quiet during operation and includes a sleep mode, making it a good choice to use next to your bed.
Best Splurge: Molekule Air Purifier
Yes, the Molekule Air is pricey, but this super-sleek air purifier works differently than most other products. You see, Molekule air purifiers use the company’s proprietary technology—Photo Electrochemical Oxidation (PECO for short)—which works at a molecular level to destroy air pollutants. It can eliminate everything from bacteria, mold, viruses, and allergens to smoke and paint fumes—and it doesn’t hurt that the unit is incredibly modern and stylish, either!
The Molekule Air can be used in spaces up to 600 square feet, and it even has a digital touchscreen that lets you adjust its speed, mode, and more. You can also monitor its status right from your phone, making it one of the most advanced models on this list.
Best Design: Blueair Blue Pure Purifying Fan, 3 Speeds with Washable Pre-Filter
The Blue Pure Fan has a cute boxy design, but it’s more than just a pretty face. This gadget cleans as it cools, removing 99 percent of airborne dust and pollen from the air, while delivering a cool breeze across the whole room.
The Blue Pure Fan is designed to be minimalistic, with just a single control button, and the brand sells compatible “pre-filters” in various colors so you can customize the look of the unit.
Best Smart: Dyson Pure Cool Purifying Tower Fan TP04 Air Purifier
Dyson sure knows how to make a great vacuum, but did you know they make air purifiers, too? The Dyson Pure Cool is a fan and air purifier rolled into one futuristic-looking device, and it comes with a bunch of useful features that you’re sure to love.
In addition to its sealed HEPA and activated carbon filters, this gadget has a sensor that detects air quality levels in real-time, sending reports right to your smartphone. It comes with a remote control, but you can also control it through Amazon Alexa, and the bladeless design is safer to use around kids and pets than your average room fan.
Best for Small Spaces: Pure Enrichment PureZone 3-in-1 True HEPA Air Purifier
You can say bye-bye to bacteria when you add the PureZone 3-in-1 Air Purifier in your home. In addition to its HEPA and carbon-activated filters, this unit also includes a built-in UV-C light that works to destroy illness-causing microorganisms.

Best for Large Spaces: Alen BreatheSmart Classic True HEPA Air Purifier
The Alen BreatheSmart Classic has a simple design that will blend into any room—because, after all, chances are you don’t want your air purifier to draw too much attention. This air purifier has a HEPA filter to capture the vast majority of pollutants from the air, and it can be used in spaces up to 1,100 square feet, which is ideal for open-concept homes.
There are a few things that make this product unique, as well. First, it has an advanced particle sensor that alerts you to the air quality using an LED light on the top of the unit. Additionally, you can choose from a variety of HEPA filter styles, including options that help neutralize odors or kill bacteria. The unit also comes in seven classic finishes to match any style of decor.
Best Energy Efficient: Blueair Blue Pure 211+ Air Purifier
The Blue Pure 211+ may look like your average air purifier, but don’t be fooled. This unit packs a powerful punch, and it can completely filter all the air in a 540-square-foot room in just 12 minutes. Not bad, right?
This award-winning air purifier has a three-stage filtration system that removes both particles and odors from your home, and its Energy Star-certified design is 40 percent more energy-efficient than standard models. You can change the look of the Blue Pure 211+ with the brand's colored pre-filters, and the unit’s single-button design makes it extremely simple to operate.
Best Features: Oransi OV200 Air Purifier
The Oransi OV200 Air Purifier has a plain design that will allow it to blend into the background of any room, but it will still do its job well, removing more than 99 percent of airborne allergens and particulates from your home. It’s best for rooms up to 400 square feet, and it operates using three stages of filtration, including a pre-filter, HEPA filter, and activated carbon filter.
The OV200 comes with a convenient remote for across-the-room operation, and it offers a built-in timer, three fan speeds, night mode, and a child lock. It has a dust sensor that will automatically adjust operation when air quality is low, and the unit also comes with an impressive 10-year warranty. What’s not to love?
Best Quiet Operation: Levoit Core 300 True HEPA Air Purifier
Small space? Levoit has you covered! The brand’s Core 300 Air Purifier is ideal for spaces under 215 square feet, and it has a three-stage filtration system that uses both HEPA and activated carbon filters. That means your room will quickly be rid of airborne particles and unsavory odors.
This air purifier is an especially good choice for your bedroom, as it operates at a whisper-quiet 24 decibels—roughly the noise level of rustling leaves. Additionally, it’s Energy Star-certified, meaning it won’t run up your electricity bill too badly if you use it all the time. Between all these features and its relatively low price, we definitely think the Levoit is a worthwhile purchase.
Best Personal: Dyson Pure Cool Me Personal Purifying Fan
If you’ve ever wanted a personal air purifier, Dyson can make that happen. The Pure Cool Me is a “personal cooling fan” with a cool dome-shaped design, and it offers 10 fan speeds, as well as both activated carbon and HEPA filters to capture 99.97 percent of pollutants and allergens.
Once the air is purified, this small unit directs a focused stream of air in any direction, and it can also oscillate 70 degrees, helping to cool down your personal bubble.
The NOMA Medium Air Purifier with True HEPA Filter (view at Amazon) is our top pick thanks to its fine-tuned allergen filtration system and reliably high performance. It even automatically adjusts its settings to suit the current quality of the room's air. Alternatively, you can achieve cleaner air within a smaller radius of your personal space (without spending an arm and a leg) with the Bissell MyAir Personal Air Purifier (view at Amazon).
