Great washable filters

By Female in 50s from Butler, PA on 6/3/2026 5:29:54PM

I have been using these washable filters for many years. They are very durable when taken care of and will last many years. I have 2 huskies so we are very well aware of the hair and the dander that go through our registers and these filters are wonderful! Highly recommend!!
