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.

I wasn't sure if this would actually make a difference but I tested it after my husband cooked with onions and when I came back into the house an hour or so later I could not smell the onion odor. I purchased this because we kept getting sick and passing it back and forth between us. I will say that within 2 weeks we had kicked whatever sickness we had had for the prior 2 months.

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.

Smaller than i thought.

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.

Gets rid of animal smell amazingly. If it’s off for the night I smell my animal immediately, as soon as I turn it on- give it a few minutes and the air is clear

These work great! And for their price they are a great deal! You can buy 3 or maybe 4 of these (so more rooms covered!) to buying just 1 SANS brand. I have 2 and can definitely tell a good difference in air quality of the house.

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.
