Review on Versatile 32mm to 35mm Vacuum Attachments (6 Pack) – Perfect for Home, Car, and Pet Cleaning Needs! by Christy Jordan

This filter appears to be the same as the 'original' that came with my Winix P150. It fits exactly, no gaps or creases, $10 less than a branded filter and was delivered next day. These air filters remind me of printers. The printer is cheap but they get you for the price they charge for replacement ink. This is also the case with this air filter. While I'm happy with this replacement, we'll see if it lasts as long as the original.
