I purchased Germ Guardian because the reviews were favorable. There was no discernable change in air quality. I couldn't return it because there's no return reason for "Doesn't work as promised" So....I did more research to find something that would accomodate a central area and cover a larger area than a small room.This model is basic with three fan speeds. No other bells and whistles, however, I don't care about app access. I would have liked an air quality feature on the machine, but that still wasn't a deal breaker.I'll let my Alexa remind me when it's time to order a new filter.This one does work as promised. I have two cats that seem to compete on who uses the Litter Robot the most.I liked that it would scoop my litter, but there's still going to be some smell at points. It's positioned in a room near where the a/c vent pulls air in to circulate through the house.My A/C company who comes out twice a year offered a VERY VERY Expensive system with a UV light and electrostatic filter. *AHEM* The filter replacements for their recommended system were ridiculous.So...I decided on the next best thing and it was just going to more old school in the Air Purifier machine world. I've never heard of this brand, but reviews (as previously mentioned) were good, and the filter replacements are reasonable.My living room and Kitchen are an open space so there's no walls between the two, just a bar. My husband seems to have some kind of mental block that prevents him from closing the garbage can lid after putting something in it, and the first thing I smell when I walk in that back door is the dang garbage can.Mom think's I'm hypersensitive, but if I can smell it, so can someone else; it's embarrassing.I got tired of walking in the door and saying "It smells in here"This machine actually does work as promised and I've been able to walk in my door and say "Hey, it smells decent in here" without any changes to husband's poor habits and no relocation of the Litter Robot.We used to be able to smell the hot, steaming dumps right after the cat went from the couch. I have not smelled it since we started using it. It's perfectly placed by the a/c area where the evaporator pulls in the air.My husband thought I had recently dusted and I told him that was not the case. So I also believe it is grabbing the cat litter dust before it gets pulled in to the area where the a/c filter gets changed. (I am at a blank on what that is called right now, but if you have central air, you will know)Sorry this is wordy, but I wanted to share my experience for someone who does a lot of research before making purchases. Money doesn't grow on trees and everything is expensive.I'm very pleased with it.

Great, powerful medium size unit, does everything it says and works awesome for Cat Hair on Hard Wood Floors, smells disappear totally on the main floor, plus plus plus plus plus for us...... Works better than they claim!!! TFH

Overall it works great. The noice isn’t to loud if your into white noise or like me that likes sleeping with a fan it’s just like it. I have two cats and most of the fur goes in there.

Seems to work well, after just half a day I can tell the difference in the air in my living room... having a smaller house (1400 square feet or so), I will be curious as to how much of a difference it makes overall.It is much louder than I expected, even on low... I would not run this on medium or high while at home, but if I think about it may bump it up on my way out the door. I was expected whisper quiet based on other comments but it is more like a white noise level... you *sort* of tune it out after a little bit but it is still quite noticeable.

Compact. Easy to use. Great for dust and pet hair removal. Different fa. Speeds. Easy to change filter. Jeeps the air clean.

This purifying unit pulls a shocking amount of dust and debris from our room and makes pleasantly quiet white noise. Puts us right to sleep.

works pretty well just not sure how to replace the filter but it collects hair and dust like crazy!

I don't know if it helps or doesn't. I just know in the high setting it is very loud. Hardly tell it's running on low setting. My satisfaction is literally right in the middle.
