We ordered from discount filters about 18 years ago and we keep getting more every time it’s needed for replacement. This is the first time ordering for the Winix air cleaner

I love these filters!! They work great and keep my furnace running really well. I’ve used them for 3 years and at each furnace check up the Tech is impressed with how well they keep my furnace running clean and efficient. I buy 12 once a year and switch them out every 30-33 days. A 12 pack is very affordable at less than $10 each.

Excellent quality Merv-11 high flow HVAC filter. Like that it is high flow and does not put a strain on the fan motor and air flow.
