“I use the coway ap-1512hh air purifier and it's been great. It's reasonably priced and does a great job with my small studio apartment. I do have to lug it in between the living and bedroom in the morning and night but that's about the only downside of it.”

“We have two of the Levoit Core 300S, and in the last year, we had had both replaced under warranty. Both had their motors fail. They first started making a squealing noise, which got louder and louder. First failed within 30 days, second after six months.”
