Easy peasy lemon squeezy! I have been buying our filters from Discount Filters for a few years now. They make the ordering process so easy, a click! They will send you reminders when it’s time to re-order - don’t worry you can create your own schedule. For those of us who change their filters a little sooner than industry standards, you can create a custom order reminder or auto order. And yes I have found their prices to be competitive… I have checked big box stores and Amazon and they really are quite competitive. They arrive within days and typically faster than they estimate. Oh, they have odd sizes too for those odd balls out there. ?

Just wish they would last longer than 3 months. Good product otherwise.

I purchased 6 Air Dust Filters from Discount Filters. The product was as advertised and they cost much less than filters from large box stores. Also, the size I needed was available which I could not find anywhere else. Shipping was on time and was received in minimal time.
