Filterbuy 16X28X6 Aprilaire 2400 / 401 Compatible MERV 11 Air Filter

I purchased these filters to replace the accordion style filters which had to be separated by the plastic pleat separators. Those were such a pain. These replacement filters fit perfectly in the encasement which held the older style filters. Just place them in the case with the wire mesh side toward the furnace....nothing further to do except place the case back into the furnace opening. I am amazed at how this filter cut down on the amount of dust in my home. These will be the only filters I will use going forward. Customer service reps at Filter Buy are great! They are most friendly and extremely knowledgeable and helpful. I would definitely recommend this company and their filters......made in the USA!

Cost ,shipping speed and quality of the filters are great.

Prompt delivery. 2 filters were damaged and they quickly replaced them. Great product

Very quick delivery on a very hard to find furnace filter. Easy to order. Great service.

Autoship program makes it easy and the filter arrived quickly.
