Our take on the 24x30x4 MERV 11 Pleated HVAC Air Filters 12-Pack

This is a 12-pack of 24x30x4 inch pleated HVAC filters rated MERV 11, aimed at capturing fine dust, pollen and pet dander while keeping airflow reasonable. The 4-inch depth gives more pleat surface than a 1-inch filter, so it typically lasts longer between changes. At $366.54 at The Home Depot as of November 7, 2026, it is the best new price among the two stores listing it, roughly $30.55 per filter.

Questions and answers

Is MERV 11 enough for allergies?
MERV 11 captures most pollen, mold spores, pet dander and fine dust. It is a good middle ground for allergy sufferers who still want decent airflow.
How often should I change a 4-inch MERV 11 filter?
Most homes get 6 to 12 months from a 4-inch filter. Check monthly and replace sooner with pets, heavy dust or long run times.
Will MERV 11 hurt my HVAC system?
MERV 11 is generally safe for modern residential systems. If your blower is old or undersized, a MERV 8 may be safer.
What does the 24x30x4 size mean?
It is the nominal width, height and depth in inches. Measure your cabinet and note that actual sizes often run about 1/2 inch under nominal.
Is the 12-pack a good deal?
At $366.54 at The Home Depot as of November 7, 2026, that is about $30.55 per filter. Compare against single-filter prices to see if the bulk pack saves.
When is the cheapest time to buy filters?
Filter prices often dip during spring allergy season sales and fall HVAC promotions. Buying a 12-pack spreads the cost across the year.
