An excellent filter that holds up for 2 months without flopping or sagging. I made the mistake of ordering filters at a much lesser price but not made by Honeywell and got what I paid for: inferior stretchy, sagging material that wants to fall off the gutter. Stick to Honeywell for quality dependable filters that rinses well, and maintain fit and function through daily use.

Winter months in Wisconsin involve heat and, depending on your heating system, very dry air. I rely on a Honeywell humidifier to keep the air comfortable. These filters are efficient and affordable. Ordering online is simple and always results in quick delivery.

We have been using these filters for several years without any problems. They quickly absorb water and efficiently humidify our house. Changing them regularly 1 per month will ensure they don't get mineral deposits and lose efficiency.
