20 Inch Box Fan Air Filter
Description
With All The Wild Fires And Smoke This Year I Wanted An Air Filter For The House And I Did Not Want To Buy An Expensive Device That Uses Even More Expensive Filters. I Designed These Clips For My Inexpensive 20 Inch Lasko Box Fan. The Clips Will Hold Any 20" X 20" X 1" Furnace Filter. I Used A Reusable And Washable Filter I Found At Lowes But Any 20X20X1 Filter Will Fit. I Designed Two Sizes Of Clips. The Large Clips Do Hold Quite Well And Would Make For A Strong Permanent Installation. The Small Clips Tend To Sag And Slide A Bit, But Do Work Just Fine. The Small Clips Are Easier To Install As They Are More Flexible. If I Had A Garage I Would Use This While Woodworking To Keep The Air Clean.
