12x24x4 Air Filters
Our 12x24x4 pleated filters are 100% made in the USA. Buying direct from the largest manufacturer in the Midwest allows you to get great low prices and fast, free shipping. For those with mild allergies, we recommend a MERV 8 rating. Moderate or seasonal allergies indicate the use of a MERV 11 filter. When severe allergies or chronic breathing conditions are an issue, a MERV 13 will provide the greatest relief in keeping the smallest allergens and contaminants out of your indoor air. All orders come with free shipping.
