Our Top Picks


Best Overall: Levoit Air Purifier

An air purifier for allergies needs to tackle mold, pollen, dust, dander, and more. The Levoit Air Purifier is the right machine for the job. This best overall air purifier is equipped with a true HEPA filter to make sure particles as tiny as 0.3 microns are captured.

A pre-filter assists the Levoit Air Purifier by screening out larger debris, pet hair, and more. To tackle odors, the activated charcoal carbon filter completes the air filtration process. Aside from the reasonable price point, what makes this unit also stand out is the automatic air quality monitor. The Levoit Air Purifier keeps tabs on the quality of the air within your home or office and can automatically adjust the fan speed to combat poor air quality.

People love the Levoit’s ability to keep the air smelling fresh and the impact it has on removing allergy triggers. It also does a great job of removing odors from cooking or other activities within the room. This air purifier can handle an area up to 322 square feet, which is on the top end of air cleaning capacity for a unit in this price range.


Best Quiet: Honeywell True HEPA Allergen Remover

The Honeywell True HEPA Allergen Remover is a popular choice for a quiet air purifier for allergy-sufferers. If you want to enjoy better air quality but don’t want to give up a peaceful environment for it, try this air purifier.

The Honeywell True HEPA Allergen Remover can tackle a room up to 465 square feet in size. It features four air purification modes: germ, general clean, allergen, and turbo. While the lower levels of operation are found to be low decibel and peaceful as background noise, the turbo level is reported to be quite noisy. Still, if you don’t plan to operate the air purifier in turbo mode too often, you’ll find this unit to be quiet enough to fade into the background.

Because it's so quiet, you may need some stronger ambient noise to help you sleep.


Best for Small Rooms: Levoit LV-H132 Air Purifier at Amazon

If you want clean air in the smallest spaces in your home, the Levoit LV-H132 Air Purifier is an excellent choice. Its compact size makes it perfect for a home office or guest room. Want to keep it on your nightstand? It's quiet as a whisper and comes with a soft two-setting nightlight to comfort you as you sleep.

The three-stage filtration system eliminates dust, pet dander, odors, and other irritants—because as much as you love your cats, you don't need to be reminded of them every time you breathe. It's so effective in fact, that it grabs 99.97% of particles and pollutants from your air. Talk about a spring clean.


Best Budget: Germ Guardian AC4100 Air Purifier

For air purifier on a budget, look to the compact GermGuardian AC4100. This tabletop HEPA purifier measures about 11 inches high, which makes it a good choice for small bedrooms or desks, but it would likely struggle to clean the air in larger spaces. What sets this budget air purifier apart is the fact that it contains a true HEPA filter and a UV-C light to kill airborne bacteria. Packing these features into an air purifier at this price is a great value.

Just be aware that reviews are mixed on whether the fan noise from this compact air purifier qualifies as noisy. Some people find it to be too loud for a bedroom or office environment, but it didn’t bother others. If you don’t mind its quiet operational hum, then put this budget air purifier to work in a small space where you want to enjoy clean air and remove common allergens.


Best with Humidifier: Venta 2 Gal. Single Room Humidifier Plus Air Purifier

Make your home or office environment cleaner and more comfortable with an air purifier and humidifier in one like the Venta Air Washer. This device will purify the air and also maintain a comfortable level of humidity thanks to its two-gallon water reservoir.

The unit works to purify the air by removing particles up to the size of 0.3 microns. Without filters, this air purifier relies on a wet, rotating disk stack that catches incoming particles. Through the process of cold evaporation, only water evaporates into the air—leaving dust, dirt, dander, pollen and more on the inside of the machine.

It’s recommended that every 10 to 14 days you clean the disk stack and interior housing of the air purifier to keep it running efficiently. There are no filters to purchase for this air purifier, which is a major plus for most users. However, the company does advise the use of an additive that helps to keep mineral deposits from building up and allows the unit to function at peak efficiency by preventing the water from beading up on the disk stacks.


Best High-End: Molekule Air Purifier



At first glance, the Molekule might look more like a piece of modern art than an air filter. The sleek aluminum design—complete with a natural leather handle for easy transportation—looks great in any home, but the real draw of this pick lies in its ability to completely replace the air in a 600 square foot room once every hour. The Molekule is an investment to say the least, but you get what you pay for. This unit is incredibly quiet, energy efficient, and easy to control remotely from your smartphone.

One of the major drawbacks of air purifiers is needing to shop for new filters. With Molekule, you can sign up for auto-refills, ensuring that a brand new filter will magically arrive at your home every six months.


Best for Larger Spaces: Rabbit Air MinusA2

For better air quality in a larger room or open-concept floor plan, choose an air purifier with higher capacity—like the Rabbit Air MinusA2. While many air purifiers require you to purchase multiple units to cover the square footage of your home or force you to move a unit from one space to another, the Rabbit Air MinusA2 can cover rooms up to 815 square feet (or 350 square feet for allergy sufferers requiring a higher air refresh rate).

This air purifier is also unique in that its slim dimensions make it possible to mount it to a wall in your home, saving on floor space. When it comes to making the most of your air quality, the Rabbit Air MinusA2 has a 6-stage process that will leave you with fresher, better air. It begins with a prefilter and medium filter to trap larger particles, then includes a special HEPA filter that has been treated to reduce buildup and increase efficiency.

Next, you can choose from one of four specialty filters to target your specific allergy triggers, such as pets, smoke, or toxins. An activated carbon filter completes the air filtration system, while a negative ion generator can be turned on to add freshness to the circulated air.

People find the Rabbit Air MinusA2 to be a useful way to purify the air and relieve allergies. The customizable filters are also unique and make this a good air purifier for smoke as well. As far as aesthetics go, the minimalistic look allows the unit to blend in, though the blue LED “mood light” can’t be disabled, which might be an annoyance for some people. Overall, the Rabbit Air MinusA2 Purifier is a higher-end choice with a greater capacity for air purification and the ability to clean larger rooms.


Best Smart: Dyson Pure Cool Link WiFi-Enabled Air Purifier

If you’re the type of person that likes up-to-the-minute reports and data tracking, you need a smart air purifier. The Dyson Pure Cool Link Air Purifier delivers cleaner air and interesting statistics. The Dyson Pure Cool Link Air Purifier will keep close tabs on the air quality of the room, making adjustments and providing you on-demand air quality reports.

Use your smartphone to check out the status of your air quality or to adjust the machine’s operation. It also works along with Amazon Alexa. This futuristic air purifier is one of the more expensive air purifiers to purchase and maintain​ since the filters are a bit pricey. It features a HEPA filter bolstered by an activated carbon filter to assist with fumes and potentially migraine-inducing odors.

What to Look for in an Air Purifier

Size: How big is your home and how much space do you have to house a purifier? Some are small and great for rooms on the cozy side, while others can take care of the air in much larger spaces. Some models require floor or tabletop space, and others can be wall-mounted. 

Features: Air purifiers come with different features that can affect just how pure they make your air. For example, some will continuously monitor the air in your home and adjust its settings appropriately, and others double as a humidifier. Consider the type and severity of the allergies people suffer from in your home to determine which features you want in a purifier. 

Style: While functionality is the most important consideration for an air purifier, if it’s going to be sitting out in a prominent place in your home, you want it to look good, too. Fortunately, air purifiers come in an array of designs, some of which are quite stylish. Your personal preference and current home decor will help you narrow down your choices.
