“These filters are far superior when compared to the generic 413 filters. Unfortunately my last order was for a 4 pack but I only received 1 filter. In the photo the Aprilaire filter on the right side is more plush and pillowy. The left filter is a generic one and feels thinner to the touch.”
“Easy to buy and install yourself instead of hiring a company to do it for more. Multipack is economical if you have storage space. High quality filters.”
