These filters was hard to find because of how old my air purifier was. However, I checked on Overstock and ordered immediately! Great buy!
The filter is worth the value
We have 2 boxer dogs and I run my purifier for about 5-6 hours a day. I have been able to use the same filter for the 7 months before needing a new one. I love the ease of changing these filter out. They are thick and really hold a lot of impurities. I will never use another filter for my air purifier.
