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.

Does a good job of removing pollen and other irritants from household air. You will notice the difference upon exiting your house.
