Filterbuy10x10x2 Air Filter MERV 8 Dust Defense (6-Pack), Pleated HVAC AC Furnace Air Filters Replacement (Actual Size: 9.50 x 9.50 x 1.75 Inches)

Got 3 son bion 10” square box fans on Amazon. Got these filters. Strapped filter to intake side of fans with Bungie cords. Fit perfect no air gap. Only son bion fans work. Other fans aren’t flat faced on intake side. (Had to hand cut a little hole through filter for power chord to plug into fan) now have clean air circulating in living room, master bedroom, family room all the time. Knocked out my allergy suffering in one day. (Added 2 20” box fans with 20”x20” filters strapped on for the same purpose and run those on digital timers cycling off and on for an hour at a time several times a day with highest MERV-13 rating to really clean the air. Cus of 2 cat and 2 dogs additions and surrounded by giant Oaks in Florida with pollen alerts every day at level 13+ which is worst levels of the chart. Saved hundreds on high tech expensive hepa air cleaners with short life cycle filter that cost 3 times as much.

Nice product
