Customer Ratings & Reviews

Bought this air purifier for my wife and son who had an allergy attack when we moved here in AZ from another country. I think it worked given that their allergies is not that bad anymore. Only complaint is the exhaust air going out of the vent tends to blow only towards once side and not evenly distributed. Not a deal breaker though since it still does its job!

We bought two units one for a office which serves as a litterbox room and one for our bedroom. The units are a little loud on their highest setting, but they work great. After about a week the smell they initially had wore off. There has been a huge difference in my allergies. I would highly recommend this product.

Many settings options. Love running this on low at night in the bedroom for both fresher air and sound masking.

Bought this for my son, who has allergies and this has really helps him.

If you want a nice and attractive air purifier then look no further. I only wish the blue LED wasn't so bright

Very good air purifier.. works perfect for a mall room

I love the Germguardian and plan on getting a few more for my house. It truly takes out dog odors and I no longer wake up with puffy eyes. It is also helping my dog that has allergies, she hardly scratches anymore and she is more content. It is worth it!

My wife and I purchased this for our house and placed it in our bedroom. We have 3 dogs and 1 cat and the pet dander was crazy. It would be all over the place, and you'd wake up in the morning sometimes with dog hair all over you due to our dogs and cat all wanting to sleep in our bed and bedroom at night. We run this machine on the lowest setting each night while we sleep and have found a large reduction of pet hair/dander in our bedroom. I was skeptical at first as some reviews said the unit has a "plastic odor", which we did experience the first couple of days, but it's a "clean" smell and it didn't bother us at all. The cat tends to lay in front of it sometimes when it's on because it does let off a little bit of cool air.

Wow, after all my research I'm glad I made this choice/purchase. The dust and cat dander has been reduced by at least 65%. Word of advice though, don't try and extend filter life by vacuuming it. Every 3-4 months just replace it. If you have a pet, smoke, or just want the air to be more sanitary, then buy this air purifier.

I was surprised how well this machine air. My brother was in the hospital and I bought one for his room. It cleared the hospital smells and the doctors really like the germ destroying feature. It's used in Eurpoe and MRSA infections have been hugely reduced.

All the dust from your house! Well, nearly all of it. There is a huge difference in air quality when it’s off compared to on. It’s running 24/7 when I’m home. I only turn it off when I leave. As somebody who suffers from allergies, this is a perfect product.

Great for controlling and eliminating odors, especially for small room

I needed a new air purifier to replace one we've had for a few years now. Even though the square footage on this one is less, it is a lot quieter than our old one and I run it all day long. Almost don't notice that it is on and I like knowing that our air quality is better because of it.

This air purifier is the best one to have with little children around. You don't have to turn on the ozone causing UV light.

Great product for the price. Works very well. Set up in bedroom and noticed the difference overnight. Only drawback is the noise. A little loud but not horrible.

GermGuardian 3-in-1 AC4825 is an acceptable air purifier. It does its job to purify the air. My son has dust mites allergy. I placed this air purifier in his room, and it took the edges off of his allergy. The air purifier in itself is not enough to keep him away from his allergies. This GermGuardian is a little noisy for a quiet bedroom, but not too bad.

My allergies were absolutely horrible. I was suffering for about 6 weeks before I decided to try an air purifiers day I am so happy I did. I have had a 95% improvement. I absolutely recommended this product!

I set up the Germguardian and forgot about it because on the low setting there is almost no noise from the fan. I did put it in the bedroom but removed it; I hardly noticed it but my wife, a light sleeper, did while trying to sleep. We have 2 cats and after a month there is noticeably less dander in the air.

Excellent filter. It is a little loud on the highest setting but does a good job.

This HEPA air purifier is great!, you can feel the difference in air almost immediately, does same as the similar products from bigger brands but for less money.
