  • great except for one thing....
Style: AC4100
No beeping buttons, no annoying display lights, and a good, strong white noise could have made this a five star item for me for sleeping - except if you set it to medium or high it makes a repeated, throbbing bass tone, which means I have to return it because I'm a light sleeper. I wish I didn't because I like everything else about it. It is pretty compact but if you had it on a desk top it would blow at your face like a fan since the air sucks in through the back and out the front (instead of out the top). But I really like the simplicity of it and the fact that you can dust vacuum the filter. It also has an optional UV light function that is supposed to kill germs, which seems handy. I know that's real in theory but not always in practice so you might want to look into it if that's important to you. ... show more

  • NOT NOISY! BREATHING BETTER AT NIGHT!
Style: AC4100
This thing is quiet. It isn't scary-noises but gives a bit of white noise (feels like ASMR). It honestly helps me sleep for that reason, too. I have severe asthma and allergies and I don't have nearly as bad reactions anymore at night.

  • Very Effective!
Style: AC4100
This air cleaner made it SO much more pleasant to spend time with my mom, who was a heavy smoker. It was a real game-changer in the quality of life for everyone who came to visit, and all the neighbors in her building.

  • UPDATED: Quality value for the money. Recommended but only for small rooms with limited traffic.
Style: AC4100
Original title: Is this thing even working? - Maybe a Pass? This is my first ever air purifier but its really hard to tell if this is even doing anything. My office is 8' x 10', and I keep my door closed most days. Other than the white noise element, it is really hard for me to tell if this is doing anything more than serving as an expensive and poorly performing fan. I wouldn't recommend using this in any space larger than 8'x10', and ideally, not even for something this "big". If you work in an actual closet then this could be the purifier for you! Maybe? 3 stars honestly because I can't tell if it's even making a difference, and feel bad giving it 1 star if I'm just not sensitive enough to notice the benefits of an air purifier. I left it running on high over the weekend and my office smelled different, but not really "better", more just weird. It is definitely NOT quiet though. On medium, it is too much for me to have a phone call in the same room. High might as well be a jet engine if you are trying to hear or have a conversation. If you want to think and block out your annoying work neighbor though, then this is GREAT! Some positives: Quality seems good. It has a sturdy metal case, and the knob seems like it will last for years to come. Uses a standard filter size so replacements should be easy to acquire. UPDATE: After using this for going on two years, and a full replacement filter life cycle, I can confirm that it IS actually doing something, haha. It does a good job of filtering out airborne dust and particulates in my small office. It also does a great job of removing odors for the first few months of the filter's use. I generally run it all day on low or medium to keep some air moving and to provide a good white-noise background. Medium is still a little much for a phone call without a noise-canceling headset. Having the office door open, or frequent trips in and out of the office do overwhelm it quickly though. I couldn't see this being of any real use in a room that couldn't be closed off or one that is any larger than 150 sqft. There is also no way to tell if the UV bulb needs to be replaced. It would be nice to include some sort of status light that would let you know its still working properly. Removing the filter and wedging the safety switches allowed me to see that it was still working but that is less than ideal. Replacement filters were easy to find on Amazon, GermGardian "E" type, and installed without any trouble. I would note that air does not blow uniformly out of the front of the filter. It tends to blow most strongly between 30 and 80 degrees to the left of the centerline when looking at the front of the unit. With almost no flow coming out to the right of the centerline. This happens to work well for the counterclockwise airflow in my office but should be considered based on your intended location. ... show more

  • Extremely solid product.
Style: AC4100
After owning this purifier for one day, its effect is very noticeable. Live in a 2BD/2BA apartment. The second bedroom is where we keep the cat's litter box. This purifier has reduced the smell of cat litter to the level that it goes unnoticed by me. We use lightweight litter and that seems to be dustier that your run-of-the-mill litter and that dust gets everywhere in that room. Also, I have not used the UV-C feature up to this point. I've still only owned this for one day, but was so happy with its immediate results that I thought I'd review. Any changes will be noted. As they say: "No news is good news." Be aware, some may say that it runs a little loud. Personally, if I were to move it into my bedroom and had it on the lowest setting, it wouldn't be too loud for me but I can see how it may be for others. If noise is an issue for you, find a different purifier. UPDATE #1: 12Jan2015 I have used the UV-C function and notice very little difference in its current environment. I run this purifier 24/7. Stand by my 5-stars so far. UPDATE #2: 31May2015 I've knocked the dust out of the filter a couple times since my last update and have kept it running nonstop since I initially review the product. Still awesome. UPDATE #3: 05July2015 I knocked out the HEPA filter yesterday and it was pretty packed with dust and the like. I take this as a good sign that it is still operating well. The recommended time to replace the filter is near upon me so I ordered another one that should be here tomorrow but I won't replace it yet because I don't think that it is necessary after the clean out. I decided to get one so I would have it on hand when I do decide to replace. Still 5 stars. No more updates will follow unless it explodes. UPDATE #4: 16March2016 So I lied; an update and yet the purifier did NOT explode yet. I changed the filter at about the one year mark after several cleanings to the initial filter. Some months ago I dramatically decreased the time that the purifier is running in a given day because it just doesn't seem necessary any longer. Recently (and I mean within the past few days) the purifier's three different fan levels have sort of leveled out. I mean to say that the LOW setting is an awful lot like the MEDIUM setting and not much different from HIGH either. I've had this happen to my automobile fan in the past. In this case, I think that some resistor(s) stopped working (well, anyways) so the fan is receiving near the same electrical current no matter the setting. The UV bulb has gone out but that might be normal for the amount of use it has seen. Strongly recommend this company. When this baby goes out, I'll be going with GermGuardian again. Update #5: 27Sep2016 No significant change. I don't run it nearly as often as I did previously (cat litter box went into a closet of its own to limit dust). The fan operates on one speed regardless of the speed selected. I'm toying with the idea of getting a higher-end model soon. We'll see. ... show more
