What customers are saying

This air purifier provides excellent air cleaning performance, effectively reducing dust, allergens, and odors. Many users with allergies or asthma have found relief from their symptoms. The purifier operates quietly, especially on lower fan settings, making it suitable for bedrooms. The HEPA filter and UV light capture and kill a wide range of airborne particles and germs. While some users note it can be noisy on the highest setting, most find it to be a great value for the price and highly recommend it for improving indoor air quality in small to medium-sized rooms.

    Believe the hype!

    Verified BuyerReviewed by - 24 mars 2022

    [This review was collected as part of a promotion.] With over 1,200 reviews and most of them have given 5 stars, I gave it a shot and oh boy… its well worth every penny. My 9 yr old son’s been suffering from morning allergy/stuffy nose (living here in north Texas). The first night we turned this thing on, he woke up the next morning feeling/breathing great. We liked it so much we’re picking one more from Bestbuy.

    This is the best air purifier no doubt

    Reviewed by - 26 juin 2023

    [This review was collected as part of a promotion.] I’ve had this air purifier for YEARS. And I absolutely love it. You can literally see the junk it’s been sucking out of the air which is oddly satisfying but also disturbing. We’ve been remodeling our home for a little over a year now and you wouldn’t believe the amount of dust we’ve been kicking up. Also having two cats and two dogs this is a must. I ordered an air purifier from Amazon and I just don’t feel like it’s doing much. I can’t see anything in the filter. So if you’re worried about which brand to purchase and if it will be a quality product I personally recommend staying away from Amazon and purchasing this one from Best Buy. I will say I do order the filters from Amazon but be leery when getting an air purifier there. First two photos are germ guardian and the third photo is the air purifier from Amazon.

    My first air purifier

    Verified BuyerReviewed by - 4 octobre 2018

    [This review was collected as part of a promotion.] I'm not even using this a week and I can smell the difference in the air. It seems like I can still smell the slight cigarette smell through the walls but it's not heavy anymore and I am wondering if it's my imagination that I'm smelling anything at times. I can finally get some sleep. Made me wonder if the neighbors whom I share a thin wall with were smoking at times so I shut it off and the smell was heavy again so I put it back on and the smell seemed light and went away, this has helped a lot. I will see how well it will works for me in the long run. So far I am happy with this air purifier.

    Decades long air purifier user

    Reviewed by - 13 juillet 2024

    [This review was collected as part of a promotion.] This will be my third of these I've owned. I started with just one for the main area. Then, due to fragrance sensitivity and living in an apartment I bought a second for my personal space/office. During this summer and the humidity and heat, my son has been using a box fan. It was time to get a third for his personal space. My family has used air purifiers since the 80s and this has me more pleased with the simplification and ease of filter change evolution.

    Decent coverage

    Verified BuyerReviewed by - 11 août 2023

    [This review was collected as part of a promotion.] Was a bit worried that my cat hair would overpower the filter, but the hepa filter in this has a coarse mesh strainer Velcro-fitted on top - easy to clear of any cat hair and has kept the filter serivceable. The 3 fan settings are adequate, low doesn’t make much noise, hi is louder but flows are decently - not really useful as a fan though. The UVC is a neat feature to have, even though I couldn’t say if that even does anything. Overall, it’s significantly reduced the dust particles I was choked with, and has helped with the days where wildfire smoke is nearby and acrid. I’d recommend it, from a ‘haven’t tried anything else’ POV. I use it in my apartment of 900 something sq ft.

    Best air purifier

    Verified BuyerReviewed by - 6 avril 2024

    [This review was collected as part of a promotion.] I just wanted to share that I've been loving this air purifier. I've tried it and put it to the test. I got my first one a few years ago, then my boyfriend and I decided to get another one for each room. It's been a game-changer for our allergies and has made a huge difference in keeping the air fresh and clean. I would definitely recommend buying it again, and the price is also really affordable.

    Very happy with this investment!!

    Verified BuyerReviewed by - 30 octobre 2024

    [This review was collected as part of a promotion.] This is a life changer! I have only one of these in my 1200 square foot home with high ceilings. I wake up feeling better where before I would always have to cough and felt like I didn't breathe well all night. I also have a dog who is in the house. My allergies are finally under control! Also the house smells freah.

    Clean air Plus UV!

    Verified BuyerReviewed by - 25 avril 2020

    [This review was collected as part of a promotion.] Wife and I have been wanting an air purifier for a while but it has always been a back burner until recently! We bought two of these to run to clean the air and especially the UV for any biologicals. I am a first responder and plan on probably getting Covid-19 at some point and I want to seal myself off in a room with one of these and the other one in the other part of the house where my wife will be to help minimize her exposure. She has asthma. Anyway... WE love these units, We picked them for the high ratings and see why. They pump out fresh clean air hour after hour and I like the blue light on the front that shows the UV is on. They are quieter than I expected but keep in mind they are a fan and the higher the setting is the louder it is. It does not interphase with tv ect. The higher the setting the quicker it pulls all the particles out of the air and replaces with fresh air! Great product by a trusted name!!! Get prepared and get one of these asap!

    Check Square Footage.

    Verified BuyerReviewed by - 14 juillet 2023

    [This review was collected as part of a promotion.] It was ok. Didn’t notice much difference. Probably needed to buy a bigger one since the box said up to 157 sq ft. Nice design but not sure I want one with UV light. After doing some research went with another popular brand. Make sure to buy air purifier appropriate for room size.

    Great Air Purifer

    Verified BuyerReviewed by - 16 avril 2018

    [This review was collected as part of a promotion.] I have two units, one in the bedroom & in the living room/dining room. I notice a difference in air quality, I have bad allergies & breathe so much better. I like that the replacement air filter is just one unit.
