    We have the unit in the living room and you wouldn’t know that it’s on. When my wife accidentally overcooked something the unit kicked the fan on automatically.

    I have a purple air device monitoring my indoor air quality and this purifier has cleaned my air significantly. It is a bit loud when it's working hard (I keep it in auto mode) but it's white noise that's easy to ignore. After the first night it spent running on high, it's been very quiet and keeping the indoor air clean. I wake up feeling much better these days, so it's doing what I needed it for: removing allergens.

    I can notice the difference with my allergies after just a few days of using the Shark air purifier. Like that it has 3 air flow levels and lights can be turned off. Only wish it could be programmed to run at different levels at different times.
