This site is a big help. We replace our filter monthly and see how much dirt we have avoided by doing so.

The house breathes better

Adapted my 20x20x1 air filter return to a 18x18x4. The only problem was the old grate restricted air and it caused a whistle. I replaced the grate with a newer one and the whistle went away. The whistle was because more air was moving through the new 4 inch filter than the 1 inch filter. Better for the furnace motor.

Perfect fit for HVAC systems

The filters are exactly what I ordered and fit perfectly. One of the systems is an odd size, but the filter is an exact replacement.

Genuine Generalaire

This is exactly what you expect it to be. I ordered from two other companies first that sent their version of this product, and they didn't fit exactly. This is genuine and I was so happy that it fit and worked perfectly.
