Customer Ratings & Reviews

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!!

From all the reviews I read about this unit I have decided the noise is not an issue as the different settings allow you to keep it down. my boy has a 120 sq foot room and works great on low and does not smell like others have said. I have not purchased replacement filters but they are reasonably priced and the sale price on this unit / color / size is great. I have noticed my sons allergies are better / we dust more / and keep the animals out of the room. the other one we bought is in the family room and you can only hear it if the tv isn't on or if nobody is talking etc...

I have 3: one in hearth room, family room, and master bedroom. They eliminate odors from smoking, cooking, dogs. Reduces dust. Kills germs when this feature is used. The air feels and is clean. Great for allergy sufferers. I love this air purifier and recommend it to anyone!

This unit does the job. I can notice the air quality improvement, our entire family suffers from allergies. Replacement filters expensive (may consider generic) it's priced cheaper at best buy than most other stores. Brother in-law stayed for a week then bought one when he got home

Noticable difference in air quality one week into purchase. Smell in child's room is more crisp and leaves a generally clean air small at all times. Very quiet.

I was so hesitant to purchase an air purifier; but with having 2 dogs, a toddler, a husband AND being a dog sitter, I needed something to “Clean” the air. I am so glad I bought this! Within a half an hour of plugging it in, I noticed the air felt cleaner and it was easier to breathe. I put it in our bedroom and immediately noticed a cleaner smell. My dog suffers from severe allergies, and he has not itches once since being in our room with the purifier plugged in!

Unit has a UV light to eliminate airborne germs with a selector switch to turn it on/off as desired. Unit has a pre-filter to trap dust and allergen particles, before filtering air through charcoal and HEPA filtering for maximum purification. All of the above filters are incorporated into one "combination" filter so that all filters get replaced as a single unit, when necessary. Unit has an indicator to alert you that it is time to replace the filter. Unit has a three-speed fan to allow for different rates of airflow. This is a decent unit at a reasonable price!

This product does what it exactly suppose to do. There are three speed settings: low, med, and high. It gets pretty noisy at the max level. However, at low the noise level is decently quiet, which is suitable during sleep. The design looks sleek and the UV light (blue light) aren't just for shows! It's actually designed to kill off germs, which I didn't know at first! After using the product in my room, you do feel a different (as my room has collects tons of dusts with the computer and other systems). Definitely recommend this to any friends that are looking for an air purifier!

I purchased this about 4 months ago, and I have to say, it has changed my life! I have two large dogs and allergies. Though my dogs don't shed much, they still have dander and they used to send me into middle of the night asthmatic fits. I wasn't sleeping a full night through without a double dose of allergy medicine and an inhaler (and even then it was iffy)...Until I got the GermGuardian. Upon first use there was a little of that "new plastic smell," but it went away after about 36 hours of continuously running it. The first night I used it, I took my allergy medicine, but did not have to use the inhaler. Did not wake up once! The second week after using it, I noticed that there was less dust in our bedroom, and I had been able to take my allergy medicine less and less (now maybe once a week if that). In fact, I haven't touched my inhaler in over two months! I am going to buy a second (larger unit) for our upstairs living area. I take the smaller one upstairs while I'm cooking if I am making something that is really smelly (like fried fish or bacon) and run it while I cook. It really helps to minimize the amount of lingering odors. It would be nice to not have to move it around all the time! The best part though...In this yucky cold and flu season, I am pretty sure the GermGuardian kept me from getting full-blown sick! I started to feel a sore throat and stuffy, but it never broke out into a full cold. I have recommended this item to four people who ordered it, and all of them said that they are noticing a huge difference in the air quality in their home. ***ONE THING TO NOTE*** You have to rinse the thinner filter off about every two weeks (and be careful, it can tear easily). I don't recommend vacuuming it (I tore it up, and it didn't seem to get all the crud out). I usually just rinse it out in the tub with cool water and let it air dry for about 5-10 minutes. It will help prolong the Hepa filter in it.

My son is highly sensitive to poor air quality. Everything from perfumes, pesticides, smoke, cleaners, detergents, actual small particle air pollution - you name it. We have used these for six years. They are by far better than any of the fancy thousand dollar machines. WORTH THE MONEY - WORTH the purchase for ANYONE with sensitivities. When you have little ones who with asthma - you will do ANYTHING. This is a win, win, win!!

I purchased this item for our medium sized bedroom. My wife and I are very happy with this unit. It is pleasant to listen to, looks very nice, and leaves our room with a lite, airy feeling when used in conjunction with the UV light. For our main part of home we use a Winex Plasma (great for large areas). The Germguardian is fantastic for medium to small areas. I believe the normal consumer will be very happy with the Germguardian. The only negative I can mention is, be advised, Best Buy DOES NOT carry in their stores neither the replacement filter for it, nor the UV replacement bulb.

I was initially skeptical about this product. I needed something that could get rid of the pollen and clean out the air in my room. My brother and I have allergies and this air purifier help clean the air from pollen and dust. On days that the pollen level are high I would start this on and close my door and suffer the majority of day doing my chores with a runny nose. When comes time to lay down and relax in my room my sinus clears up. There is 3 mode for this product and yes there is a humming sound. It's not that loud on the first notch but when comes the 2nd and 3rd it is obnoxiously loud but I can sleep soundly on the first notch. The downside to this product and maybe it's just me cause my brother doesn't suffer from it but it dries my nose and throat to the point it's unbearable. I have to shut the machine off before sleeping in order to feel comfortable. My solution for the dryness is to add a humidifier to it to keep the moister in the air.

I put this air filter in my large living room, and it’s perfect. I was worried about it being small and not being able to tackle such a large room with a connected kitchen and additional living area, but it keeps all smells at bay and keeps the air clean. I will most likely repurchase one for the nursery for my baby since it’s such a quiet unit. It can get loud on the highest setting, but nothing too extreme. Definitely recommended, especially for the price.

I grew up in a coal mine in West Virginia where clean air was unheard of. Due to our current living conditions we are back in the same situation. Our family dog has noxious gas... This device has brought her emissions down to California safe levels while helping with our allergies and airborne dust particles. Recommend if you have dust, pet, and seasonal allergies.

I've only been using this for about a week now, but have already noticed a slightly better air quality in the room I put it in. I've been "deep cleaning" the house and will bring this with me to the room where I'm stirring up all the dust that's settled over time. It has been doing it's job, as I've needed to clean (not replace) the pre-filter 3 times already (we have a very dusty house.) As for the noise it makes, it's not really that loud at all. Definitely noticeable when on high, but I would describe it as a "normal" fan noise.

Got this for my son's apartment which has had a funny smell since he moved in. There was a significant improvement in the air quality after running this for a couple of days. He keeps it on when he's home and says it continues to help. I'm very happy this works so well especially since the price was much less than other air purifiers I looked at. Thinking of buying another one for my house too!

This air purifier is great. As soon as you turn it on you can tell a difference in air quality. I have this one in my room and the larger version in my living room. The filters are easy to change also. You can't go wrong with this purchase.

I have allergies and this purifier has truly made a difference for sure. I have one in my living room and one in my bedroom and definitely notice the difference in the air. Not only does it remove dust and allergins, it also helps to rid the air of odors as well. I love this air purifier so much that I bought a second one!

Great air purifier for a bedroom. You can tell after a short time that the air you're breathing is cleaner. I stopped sneezing and during allergy season wasn't suffering and I have terrible allergies. Only drawback is its a bit louder than I expected but that's not a big deal. Anytime I clean I turn it on before I start and I have no coughing/sneezing.

This machine provides a noticeable difference in air quality for the room it is in. I ran it at full strength for 24 hours, then I left it on at the lowest speed. It keeps the air fresh and is quiet. I have since purchased more for my home and given to others as a gift.
