Guest guest Posted May 10, 2002 Report Share Posted May 10, 2002 We have found a cheap and efficient way to clean the air of allergens. You buy a box fan (20 inch x 20 inch) and put a 3M filtrete (20 x 20 x 1) ultra allergen filter on the back of the fan, sealing off the edges around with duck tape. We have found that this really works. Albert d701@... Quote Link to comment Share on other sites More sharing options...
