I felt like the air in our house is always dusty and I have no idea why! I’ve been using this new filter for a little while and it’s helped to make a huge difference in our air quality. There is practically no assembly required! I love that there is a child lock for the buttons and it’s super quiet! I’ve been keeping it on auto mode and I don’t have to worry about it. I put it out in our refinished shop and it started out at 65%, yikes!! So now I defiantly need a second one!
