Amazon Customer: This thing is amazing!!!! I NEVER smell dog or cat anymore and neither do my guests. It's not loud like everyone else is saying, it's quite quiet. I will be getting another one for my second floor.

Amy: I have bought many types of air filters. All ranging from $30 up to $400. However, this filter has beat all of them. I live in a 1200 sqft. house with 4 cats and 2 litter boxes.( If you're a cat owner, then you probably already know, that no matter how often you clean the boxes, there is always a lingering smell. ) I've noticed after a day of use, that this filter has cleaned the air to the point that even my guests no longer notice the smell of the litter boxes when they enter my house. This is a huge relief for me due to always being self conscience of the smell. I also like that the filter is quiet. The noise is low enough to not frighten cats and to not keep me up at night. This filter also has settings for how much air you want the fan to blow out ,as well as, how long you want the filter to run for. I usually set my filter on level 3 for the fan and have it run for 8-12 hours a day. Those settings seem to do the trick with keeping my air clean and pleasant. :)

CJ Bailey: The media could not be loaded.  Update: The company contacted me and offered a replacement unit. The replacement unit arrived quickly and worked much better. The unit did not rattle or make grinding noises as the first one did. After several days of use on level 2 or 3, the filter had picked up enough dust to prove it was working!
Great customer service and the unit seems to work well. The push button sensor to control the power and fan level is less than ideal, but the mode settings and quiet mode are a plus.
Overall, it seems to be a good machine for being only an air purifier.

Prior review:
This machine vibrates and makes a lot of noise even at the lowest settings. The highest setting sounds like a jet engine. Doesn't seem to work. I checked the filter after a week of use and doesn't seem to pull anything out of the air. I have a smaller machine in bedroom that works much better and quieter.

Richard KissickRichard Kissick: The media could not be loaded.  I needed a good air purifier for just my mom's room, where I found this one, really good specs and decided to give it a try. I was not dissappointed, this one works great. First off, it is easy to feel that it pulls a lot of air through both sides of the intake vents and the top air out, where the round fan and grill spreads the clean air outwards to every direction too. Secondly, I love the display, very accurate, shows the exact air quality and when less than good air is pulled in, the display changes accordingly, showing to me, that it really does monitor the air really well. Lastly, the air filters are key to this and they are easy to get replacements. Also this type of filter is very easy to blow out with a good air compressor too, adding to the length of use and saving money too. Hard to show how nice this one is with just pics, so I did a video to show. No cons, really worked out great for me, where I am very happy with the purchase.
