Changed size
on November 14, 2026
Posted by: Customer
I have now found out that you changed the ACTUAL size of the filter and now I have to order a CUSTOM 16x16x2 filter. Why does it say it’s 16x16x2 when it really isn’t.

I didn't need as many as I ordered, but the lower price for the larger amount was hard to pass up.

The Right Furnace Filter

Our furnace requires an odd size but Filterbuy always has what we need. They ship right to our door so using them is the only way to save money & time.

Not Two Inches Wide
on October 12, 2026
Posted by: Customer
I replaced my existing two inch wide filter with a Filterbuy. The Filterbuy did not fit properly as it was too wide.
