Questions and answers

Is MERV 4 enough for a home?
It captures larger dust and pollen but not fine particles, smoke or pet dander. It suits low-traffic areas or systems that need high airflow.
How often should I wash it?
Rinse it every one to three months depending on dust load, and replace it after about 12 months of use.
Can I cut it to a smaller size?
Yes. The pad can be trimmed to fit nonstandard slots, though cut edges may leave small gaps in the frame.
How does it compare with a pleated MERV 8 filter?
A pleated MERV 8 catches more fine particles but restricts airflow more and is disposable. This one favors airflow and reuse over filtration depth.
When is it cheapest?
The best new price is $16.98 at The Home Depot as of November 7, 2026. Check the price history for seasonal dips.
