Discount filters.com often has these filters For around 35 each or less with coupon. Sign up on website. Seco was sending to that site but it’s cheaper to buy direct

I have been using MERV 11 filters for about 2 years. All filters will restrict air flow to some extent, but I get plenty of air flow, heating and cooling, and better filtration. And the system runs quieter. Your AC provider will only give you a wild educated guess. You just need to replace the filters more often, but they definitely perform better than MERV 8 filters.
