Customer Ratings & Reviews

It's quiet and it looks good. I have seen a big difference in the air quality since I bought this purifier.

cleans and freshens the air not to loud but never ran above the low setting, filters pricey

Nicely built and filters tons of air. Quite and nice looking.

I did a lot of research before buying this. I use it in my kids bedroom because he has allergies. It has made a huge difference in his sleep. I can tell the difference when I walk in the room and breath the air. The quality of air is much better in his room than anywhere else in the house. Works great at purifying Air and removing smells.

Very nice filter and quiet. Filters are a bit expensive

I bought the GermGuardian 3-in-1 True HEPA Air Purifier about 4 months ago after reading lot of reviews. I turned it on for the first time and closed the door behind me and I came back in an hour later, and I was amazed at how much fresher the air was in the room. Then I turn it on while I was cooking and I could not small much after I finished, which make me believe that theGermGuardian Purifier really helped. The only flaw with the GermGuardian is that it is very loud on the highest fan setting, but lowest level setting is ok. GermGuardian makes a valiant effort and I bought second one for my bed room, as well as I bought one for my sister. Best Buy has best price for this product when it on sale.

Bought this for my small bedroom. Does exactly what it is suppose to, move and clean air. The pre washable filter is great as you can actually see dust collect before it enters the HEPA filter. Have it running on low pretty much all day, and I have definitely notice less dust bunnies collecting under my bed (I have tile flooring). I would consider this for a small sized room, probably not the best filter for a large room.

I found out after getting cats that I an allergic to cats. I was beginning to lose sleep and was waking up congested and having a headache. I bought two of these and began moving them around the apartment. Within a week the effects of the cat dander were greatly reduced.

Works great. Easy to clean. A little loud though. Takes odor and helps to cut down pet dander.

I've had this air purifier for over 2 months now, running 24/7, and it's still running like the day I took it out of the package. I can see all the dust it's collected by opening the filter. Overall I'm very happy with it and considering a second identical one for another room.

Super quiet on low and medium speed, still quiet enough on high. Efficiently removes household odors in a short period of time. Generous Energy Star rebate! Replacement filter cost a bit high.

At first I was skeptical on spending this much money for a purifier, but after reading all the reviews for this item I Took a gamble and purchased one and I haven't been happier this thing works wonders and for someone who has allergies this thing is amazing. I don't regret buying it and if money were no object I would buy another. On the first lowest setting you can barely hear it the second setting is somewhat noticeable while the highest setting you can definitely hear but still provides very good white noise. The only con I can find is if you have to sleep in pure darkness don't use the UV see The only con I can find is if you have to sleep in pure darkness don't use that UV-C light, but it can be turned off. Wonderful product that works!!

We moved to an old house and since we moved here, my son and me started to constantly have running nose due to allergies. After few months living this house I decided to search for an affordable option for an Air Purifier... watched videos and read reviews until we decided to purchase GermGuardian 3-in-1. The deciding fact was the price. I went to near Best Buy and purchased 4 pieces, one for each bedroom... and let me tell you... right in the first night we felt a major difference... I remember I used to sneeze every single day, several times a day... now, I remember to sneeze just once on the last 2 weeks...I'm very happy and super recommend to every one...

I highly recommend this item. I have been running to doctors for years and on meds for my sinus condition. After two week of running this air purifier at night in my bedroom, I no longer need the meds. I am so happy all my sinus problems when away. I am getting a second one for my sister who has bronchitis and sinus problems.

This air purifier is miraculous. I recently suffered from a sinus infection after moving. I slept with Germ Guardian on overnight, and my symptoms were almost gone when I awoke. I also own a cat and a dog, and there is nothing like walking into an apartment that would smell of animal only to smell--well--nothing. I highly reccommend this product to pet owners, those who suffer from allergies, or anyone who wants a fresh, yet neutral smelling apartment (as opposed to all the air fresheners on the market).

I have had this GermGaurdian for a year now and it has really cut down on the dust in our bedroom. It is designed with 2 filters, the first catches larger dust and then the hepa gets all else. About once a month I pull the back and vacuum it, it is always white with dust. Have replaced the hepa once.

Always skeptical about these air purifiers but it captures tons of dust in the black pre-filter before the main filter. I purchased it because I was waking up with headaches and thought I would try an air purifier just to see if it was just the dust in my room. My headaches are not as common as they were, so maybe it works!

Works very well in a large 3 bedroom house. We switch it from room to room every couple of days to make sure each room is getting the best quality air and I have noticed a huge drop in amount of dust in the rooms whenever the filter is in there. My daughter sneezes less and we have been healthier overall. Very good buy!

This was a great purchase. Small, quiet and does a fantastic job of cleaning the air of allergens. Much less sneezing in the house after purchasing this filter. Definitely recommend

Bought this as a Christmas gift for my daughter who has 2 inside dogs. Although I cannot attest as to the maintenance of this unit, I have noticed the air quality has improved in her house when I go and visit. I'm thinking on getting her another one for this Christmas for the back of her house.
