Economical

If you're just looking for a basic filter for an economical price, getting the four pack of this brand is by far the best deal compared to others

Ive used these filters for

Ive used these filters for four plus years. Theyre cost effective. Theyre east to instal. My gas and electric bill are always at good and better than my surrounding neighbors. Im sure some of the credit is due to having great filters.

I ordered Filterbuy 16x25x4, and what I received is 16x25x3.63. I want a filter that fills the whole chamber.

reply from Jena R.

Thanks for your feedback. HVAC filters are listed by nominal size, which is the industry standard. The actual size of a 16×25×4 filter is slightly smaller (about 3.6–3.7 inches thick) to ensure proper fit and airflow in the filter housing. The actual dimensions are noted in the product details.If you’re looking to fully fill a deeper filter chamber, you may want to consider a 5‑inch filter, which may be a better fit for your system. Our support team would be happy to help with an exchange or recommend the right option.

Not 4" Thick

These are less than 3.5 inches thick and do not fit as described.

I returned them

The filters that I ordered were really 16x25x3-5/8 Didn't fit and then had to pay to return, when that was not my fault. I think your business needs to be more accurate with sizes
