“Um-- it's no joke. At first, I was a little disappointed that it wasn't kicking on automatically while I was cooking since reviewers mentioned that a lot but then I realized I wasn't really cooking the types of foods that produce strong odors. It DOES seem to ramp up into it's higher filtering modes (from the eco mode) whenever my bird starts to preen, thus”

“Im happy with this, although I paid $119 when I bought it. Nearly silent on the regular setting, and it gets more powerful when it detects a problem. I know it works because whenever I cook it starts blasting.”

“I have one at each work bench at my work (5 stations total), they completely filter out any bad flux smells. Adjacent offices stopped complaining when we installed these. They were put in for COVID, so each employee had a fresh air supply, but had the added benefit of working well for fumes. The auto setting works well, it kicks in within seconds of solde”
