My wife and I have been hearing a lot recently about how natural gas stoves can have a detrimental effect on air quality in the home, so we decided to give this air purifier a chance - I'm so happy we did! It's super easy to setup and so quiet that you can barely tell when it's on, but it makes a noticeable difference in the air quality in our bedroom. It's wild too because, even though it's half a house away from our kitchen, you can see the reading almost immediately jump up, showing that there's been a marked decrease in air quality in the home - No problem for this guy though, with this purifier running, the level drops back down to a safer level in a matter of minutes!
