Review title: Does its job, Amazon definitely has the best price
Product review: My aunt gave me her old Hunter tower air purifier and I replaced both this HEPA filter and the prefilter when I brought it home. The prefilter I change every 3-5 months and vacuum it once between my replacement intervals, and this HEPA filter I change every 12-18 months. There's a sticker inside my air purfier that says they recommend replacement every 90-180 days which seems excessive to me. The air coming out of it still smells clean, the filter isn't black, and I live in the city where it's pretty dusty.I run it pretty much all the time when I'm home. It definitely makes a difference. I have allergies and I sleep better - plus, it circulates the air while filtering it which is always a plus.Amazon has by far the best price AND is by far the most convenient. I find myself buying more and more on Amazon!
