The filters do not fit.

The filters do not fit. Actually measurements are smaller than described size in every dimension. Less substantial than the honeywell filters I was replacing.

Air Filter Buy Them

Automatic shipments and I replace them despite looking like it’s not needed. Why? Get rid of what is not visible I guess. Filters made well and hold up.

Just replaced first MERV 13 Pleated Air Filter from FilterBuy. It held up very well and caught a lot of debris. Highly recommend.

Moved into this home and was unfamiliar with the heating/cooling system. Fast forward to water pouring down one side of the furnace. Called, on a Sunday no less, and the repair gentleman showed us the corroded filter. He replaced the filter and the entire system is working perfectly.

I dislike the blue colored filters
on March 29, 2026

The filters work fine. But I would rather have white filters so I can more easily see the amount of dirt on them. The blue filters make this difficult.
