18x18x1 MERV 13 Pleated Air Filter

The air filter is better than the one supplied by the retirement community where I live. I have lots of allergies and that has improved. Wish you made a HIPA in 18x18x1.

Very fast service and great products. Great at stocking irregular filter sizes that arent at chain hardware stores.

Was reluctant to purchase MERV

Was reluctant to purchase MERV 13 because of concerns about air flow restriction. Flow is as good as before and feel better about the increased filtering.

These filters fit our odd size ac unit and it is amazing how much they seem to grab from our ac system, the change in color from clean to dirty, wow, we change every 2 months!
