Customer Ratings & Reviews

My wife and I got this to help move and filter air in our apartment which is a bit stagnant- all of the windows are on the same side of the apartment and we don't get much airflow when we open the windows- so our home is stuffy. The Germ Guardian moves and filters the air for us so it always smells fresh when we come home.

My fiancé is able to breathe again thanks to this. She loves it. It pretty much stays on 24/7 and just walking into a bedroom from the living room, you can feel and SMELL the difference. This is great. Thinking about buying a 2nd one.

I received the Guardian Technologies AC4825 germguardian 3-in-1 Air Cleaning System sometime shortly after October 3, 2015 (shipping date) and put it immediately into service. On December 19, 2015 I took the unit out of service and cleaned it in accordance with user manual. When I put it back into service, the UV light would not come on. Thinking I could have damage bulb by banging it while hot, I ordered a replacement bulb. On about December 27th, I received the bulb and replace the one in the unit. On placing the unit back in operation, the UV light would still not come on. On December 30th I called Guardian Technologies customer service. Although still under warranty, they advised me that at my own expense I could purchase packaging material and pay to ship the unit back to them (also asked me to insure it at my expense) and they would have a technician look at the unit. Let’s recap, unit broke in 3 months and I was to spend my own money to send it back to Guardian Technologies under warranty.

I've had the GermGuardian - 3-in-1 True HEPA Air Purifier - Gray for 6 months thus far and it still works. I purchased it because I was doing housing cleaning and all the dust happened to stay in the air. So I saw the great reviews and for the price of this Air Purifier it was reasonable. As far as the product goes, I don't have any negatives, it's been good. Only thing that you might need to do is replace the filter and the light bulb in the near future which is fine by me.

Amazing air purifier super useful and practical to Move

My Allergist recommended that we look into purchasing an air purifier for my 6 yr old son who suffers from seasonal allergies. I ended up running a few Germ Guardians throughout the house. You can definitely notice the difference when going over to someone's house. I'm glad to report that my son's allergies have gone away in the last few weeks. It has also helped with him sleeping throughout the night, cough free!

Nice item. Easy to use, filter easy to change. Not to noisy, recommended.

Still running strong after some falls and running almost 24/7 for almost 7 years. The replacement filters used to be cheap but they have double to tripled in price. The unit is rock solid tho and still runs well to this day.

glad I purchased this product,I suffer from allergies and this allows me to sleep more peacefully

My kids suffer from asthma and common colds often. I bought this and shopped around for the perfect one. And I found this to be the best. And for a reasonable price. Every time I walk into their room it smells so clean. Definitely worth the money.

I bought air cleaners for a lot more money, and they did no better than this one.

I've had this about 2 weeks now, it seems to be working well it is hard to tell whether or not your air is being cleaned, but I am sure I will be happy when I see everything the filter caught.

Wanted an air Purifier for the bedroom. This particular one has been plugged in and running for 3bmonths straight. If you like a fan at night, the noise won't bother you otherwise it can be a little noisy.

This air purifier can beat any high priced competitors.

This little machine is one of the best purchases I've ever made. its completely changed the environment in my room. The air is so clean and the room itself if more comfortable.

I removed extremely moldy (black mold) linoleum/wood flooring from my previously flooded basement. I had a dehumidifier and ionizer fan (do not use it made me extremely sick) running for 3 days straight. 3 gallons of liquid were removed from the room, however, the humidity never dropped below 60%. I ditched the ionizer and placed the purifier in the room, with the dehumidifier. Within one hour the humidity dropped from 60%-50%, and the unbearable smell of mold was nearly gone. Only a few hours in, I’m extremely satisfied with this product. If I have any issues I will make sure to post my concerns.

This air purifier has greatly reduced allergens around my home. Very quiet, can be run while sleeping, or even while watching movies/television.

Works great. I can tell the difference. I use it all the time in my kids room.

This is amazing. I use it only of course when I shut my door at night and have the windows shut. Otherwise I don't use it when the windows are open. But what a huge difference in the smell of my room immediately. With it on after an hour or less even the room smells so clean in fact all I can smell are the clean sheets or a very clean clean smell from perfume soap perhaps. When I don't have it on there seems to be other smells. It's just incredible really does clean out the air. I love the smell of my room with thus on. Very clean smell.

I purchased this to use in my office. As far as I can tell it does make a difference in air quality. It makes a little noise, so if you're a light sleeper getting this for the bedroom it might not be a good idea.
