10 Reviews: Best Air Purifier for Allergies (May 2023)

This device uses cutting-edge air filtration technology. Its main filtering technology is an electrode generator, which captures pollutants with a filter plate. Although the X3 uses an ionizer, it is CARB certified, meaning it is completely safe to use. The device is simple to keep up with. It has a Filter Cleaning Indicator feature that will alert you when the filter needs to be cleaned.

I was looking for a nice and quiet air purifier for my home based salon.
I did my search and found airdog. I am so glad that I made this purchase.
I can tell the cleaned air and it’s so quiet that I can run it all day!! Love it!

The Clean Sense IQ technology in this Shark HEPA air purifier monitors air quality and automatically adjusts the power and settings to keep your air clean. Six high-speed micro-fans and an anti-allergen multi-filter work together to clean the air in your home, removing 99.97% of dust, dander, allergies, smoke, and odors. This air purifier, in addition to being one of the quietest on the market, includes an innovative odor lock and high-density carbon smoke absorption, which keeps cooking odors and odors from cleaning products at bay.

This thing is not small and I did not expect it to be. Its large and cleans large spaces. Very well made, extremely quite especially in auto mode. I got it at a treasure truck price so about half of what it's selling for now. This thing is worth every penny of full retail. Really well made, very high quality. I am a really picky person but this exceeds my expectations. I did not expect this, pleasantly surprised. 2 year warranty so I expect it to stay together.

Are you want to cover a large area? With the Alen BreatheSmart 75i Large Room Air Purifier, this isn’t an issue. Without creating a lot of noise, this air purifier cleans up to 1,300 square feet twice an hour. Even at Turbo speed, Alen claims that BreatheSmart’s technology is twice as quiet as those of its main competitors. It’s roughly 27 inches tall and 18 inches wide, with a control panel on top that includes an air quality indicator light that displays the room’s air purity in real-time on an easy-to-read display.

This purifier is absolutely amazing, not too loud, beautiful and has one heck of a HEPA filter - not some small flimsy filter oh no not this machine - best of all it works fantastic - filter lasts 12 months, less money spent on replacement filters. This purifier has cut down on dust and funky little household odors are gone - the warranty is amazing once you register your machine. Energy usage is some of the lowest I’ve found ....you won’t regret this purchase for your home

This compact Levoit model is equipped with a HEPA filter that removes 99.97 percent of dust, pollen, smoke, odor, mold spores, and pet dander and is compact enough to fit on your desk. It filters up to 300 square feet. It’s a great low-cost alternative that avoids high-tech features like UV and ionization that are more frequent in this price range. It instead has a three-stage filtration system with a pre-filter, HEPA filter, an activated carbon filter. You can also customize the purifier’s speed and volume with three fan settings.

I bought this for my daughter to use. She had recently moved and was having to keep the cat's litter box in her bedroom, and even with cleaning it every day she was having issues with smell. I sent this to her and she claims it works miracles. She no longer smells litter box in her room!

This Honeywell HPA100 doesn’t look like much—it looks like a space heater—but Honeywell is obviously hoping you’ll be more interested in what it can accomplish. This model is meant for medium-sized rooms (about 155 square feet) and includes a real HEPA filter that ensures 99.97 percent particle removal down to 0.3 microns. The top of the device features a control panel that allows you to choose from four different cleaning settings (which affect the fan speed and overall noise level) as well as an auto-off timer so it doesn’t run endlessly.

Me and my wife love using this, before we sleep I just turn it on, and will shut off in the morning, there’s a timer and dimmer for the lights

Looking for a better air purifier but don’t want to invest in a larger device that would take up too much space in your small apartment or bedroom? This Molekule Air Mini purifier is such a great choice as it can filter the air in small spaces up to 250 square feet every hour. Moreover, with a 30-decibel “Silent Mode”, it’s also amazingly silent. This air purifier for allergies also employs PECO filters, which use nanotechnology to eliminate viruses, VOCs, allergens, bacteria, and mold, eradicating the widest spectrum of pollutants.

Love this air purifier, my home feels so much more clean and fresh and the noise level is almost unnoticeable. It can be easily moved and can be controlled by my phone. I’d love to get these for every room in the house. And it’s so aesthetically pleasing, most air purifiers don’t have that quality.

This is the best choice if you need an air purifier that can filter an entire large living room or even your entire home. PhoneSoap claims that its air purifier can clean up to 400 square feet and replaces a standard filter with a proprietary technology that can prevent viral particles as small as 14.6 nanometers, even smaller than those that can pass through a standard HEPA filter. Furthermore, it uses a plasma field to trap and destroy germs in the airflow that passes through it, as well as graphene plates to filter out polarized particles.

I'm well pleased with my recent purchase of an AirSoap. It is very quiet, attractive and has performed well in the three weeks I've been using it.

The Airmega 150 air purifier from Coway uses a three-stage filtering method (which includes a pre-filter and a deodorization filter) to remove 99.97 percent of particles from the air. Their Green True HEPA filter is uniquely developed to decrease and eliminate airborne allergens such as pollen, pollution, and dust mites. It’s simple and compact, with a floor area of up to 214 square feet, making it ideal for bedrooms, home offices, and smaller flats.

Quiet and beautiful. You can tell that it’s been very well designed and it’s clear why this has won design awards. Works great just like other Coway Air products. We bought three and Are very happy with our investment.

An air purifier, such as the Germ Guardian, is a great way for pet owners to reduce the amount of pet hair and dander floating around in the air and landing on the floors and furniture. The effective filtering system catches both large and small particles such as dirt, hair, dander, and dust, as well as odors from pets. While its UV-C light kills bacteria and viruses in the air, so it will not only lower the number of germs in your home but will also keep your home healthier during cold and flu season.

Love it! So far is great addition to our bedroom. I definitely breathing a germ free air all night long, having allergies and all I love it. I am sensitive to the noise as well light but and is not too noise. I usually keep on during the day UV light and turn it off by night just because the light is bothering me in general. I love the White color

Not only does the Hathaspace Smart Air Purifier have a remote control, but it also has the computer intelligence to detect air quality and modify itself accordingly. This unit takes continual readings of the air quality in the room it’s in using a smart sensor. It has a five-stage filtration technology (including an ionizer and a HEPA filter) that can remove up to 99.97% of allergens, capture dust, pet hair, and dander, and eradicate odors.

Bought this for my son who has asthma. He sleeps so much better thru out the night now.
