Small but beneficial
Good buy. I have 2 cats and had guests over, one of which is allergic to cats. I turned on the purifiers (I purchased 2) a couple hours prior to guests arriving and after cleaning. No reactions from the guest with allergies. They stated a pleasant experience. You can hear the humming of the fan but it isn’t a nuisance. More like a small fan being on in a quiet room. I am pleased with the purchase.
