The 3M Filtrete 24x30x1 MPR 700 is a pleated disposable HVAC filter rated MERV 8, aimed at capturing dust, lint and pollen while keeping airflow high. It fits standard 24x30x1 return grilles and is sold here as a 6-pack, enough for about a year of changes at the usual 60-to-90-day interval. At $59.99 at Walmart as of November 7, 2026, the 6-pack works out to about $10 per filter, which is a normal-to-good price for MERV 8 pleated filters in this size.

Owners of Filtrete MPR 700 filters generally report less visible dust and steady airflow, and many buy them in multipacks for the value. Complaints center on fast loading in pet or renovation households and on the filters not being as fine as higher-MERV models.
