Q: Questionwhat is the proper replacement filter for this machine?

Asked 2 years ago by hello.

• A:Answer I have this one, and it's predecessor. One thing I love about them both is that they come a part into several washable pieces. The outside cover (1st stage filter) goes into the washer (cold water) The base can go into the dishwasher. Take the big filter outside vacuum it and blow it out with a compressor. It becomes quite clean and reusable. I have had the original filter on my previous unit for 3 years. I have 3 very furry medium sized dogs. And it still cleans the air nicely and prevents the allergies in the house from flaring up.
