I recommend Filterbuy

Have bought multiple sizes multiple times. Usually order 12 filters of each size for the best deal. My ordered products come very quickly. Have recommended Filterbuy to friends and they have used them and are happy with their orders.

Been purchasing filters from them

Been purchasing filters from them since Covid. Never any problems. Always arrives on time and in excellent condition. A lot easier than trying to find the size you need at the big box store.

Flimsy cardboard casing

Posted by: Theresa H.
Was difficult to install because the cardboard casing was so weak. Concerned about how much trouble it will be to remove in 3 months.
