GermGuardian - 161 Sq. Ft Air Purifier - Black

I have been running my air purifier 24/7 for almost 2 months now. I haven't had any problems with this unit. PROS: 1) Really cleans the air- after just a WEEK of use, the outer (carbon) filter was covered in dust! Disgusting, but I'm satisfied to know that wasn't in my lungs. I vacuum the filter once a week. 2) HEPA filter. Although I can't actually "see" what it is catching, I know it is helping my air quality! I live in Utah where the inversion pollutes the air on a regular basis during the winter. This air purifier gives me peace of mind, knowing that when I come home I am in a clean air environment. Not only that, but it catches dust mite allergens, pollen, plant spores, bacteria, fungi, mold, smoke, dust..... We are definitely sleeping better at night, not waking up with the usual "stuff" that you have to clear out of your throat in the morning... catch my drift? 3) UV light- peace of mind that the germs that are caught by this thing are killed. 4) Catches SMELL (carbon filter)- I am used to smelling leftovers when I let my pots/pans soak in the sink overnight. Not anymore! I know this works because one time we went out of town overnight and turned the unit off. When we came back, our apartment smelled like soaking dishes/leftovers. A smell I'm glad to be rid of using this unit! CONS: 1) When I first got this unit, the lowest setting was pretty quiet. It is noticeably louder now. However, at this setting me and my husband are still able to sleep with the unit in our bedroom at night. AKA not too loud for sleeping (and I used to sleep strictly with earplugs for 2 years straight, so that should tell you something!). Because the fan got louder, I rate this product 4/5 stars. I hope it doesn't continue to get louder. I will update if it does. 2) When we first used it, it did have a "new" or plastic/carbon smell to it. I imagine this was the carbon filter. The smell was gone by the second or third day. I recommend this product. It is the best Air purifier/HEPA filter you can get for this price range. Obviously if you spend more money, you can get a much better product that will cover more square footage. **IMPORTANT- the 22" model can be used up to 155 sq. ft. The 28" model can be used up to 193 sq. ft. Buy according to your needs. AKA, measure the living space you want to use this unit in. In bigger rooms you will need MORE THAN ONE UNIT if you want this product to work effectively. Just an FYI.

I purchased this in November and really wanted to give it time before reviewing. On that note, I highly recommend the Germ Guardian for bedroom use for a couple of reasons. It's almost completely eliminated nighttime suffering from seasonal allergens and even kept many germs from circulating within our family during the cold months. I've run it 24/7 since plugging it in and it's still running the same as day 1. It's not loud in my opinion, the fan level is adjustable and the high level is like hearing a fan; nothing crazy though. We turned its filtering level up for when someone was sick and low for regular run time. It's hardly noticeable on low. I highly recommend this for allergy/asthma sufferers and kids in close quarters (sharing a room) because it's helped prevent so much. On a side note, the filter is super easy to change and the light came on for the first time (June 2019) since we purchased the unit (November 2018). I wish I'd thought about replacing the carbon filters before now, definitely will more frequently for teenager stink. It's already noticeably helping that since changing both filters. Reset the filter change light by holding down the button ;-) I'll likely be purchasing more for the remaining bedrooms.

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.

My wife and I purchased the air purifier for our daughter and my wife herself. If you close a room out with the purifier on, You can really feel the difference in the air compared to the other rooms around your home. We used the purifier extensively everyday and got 15months out of the filter compared to the 6-9months the manufacture gives. I highly recommend this product for cleansing the air if you suffer from a lot of allergies like my wife does. It has really made it an ease for her during the spring season.

This has been amazing at night in my bedroom when sleeping. It has improved my Asthma and Allergy symptoms. The uvb light is a little bright but can easily be turned off when needed. Highly recommend one of these if you suffer from allergies.

It’s the first HEPA filter I’ve owned in years, and it does an excellent job. Functionality - it gets the job done. It’s relatively quiet, the cord is long enough to position away from furniture but not so long that you risk tripping over it, and most importantly, it doesn’t scare the cats so it’s safe to place in the general vicinity of the litter box when necessary. It would be nice if it had a timer feature and if it had a natural way to wrap up the cord when not in use.

Works amazing! Noticeable difference in air quality. Even removed odor of skunk from the air (we have skunks that live in our neighborhood).

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.
