MERV ratings let you know the efficiency and level of filtration that an air filter can handle under normal circumstances. The higher the MERV rating, the finer the particles are that are filtered our of the air in your home. Many air filter retailers use MERV or a similar rating to rate their air filters.
MERV Rating is the primary rating system used in the industry, both domestically and internationally. Established by the American Society of Heating, Refrigerating, and Air Conditioning Engineers, MERV rates a filter’s ability to capture and hold particles and pollutants.
MPR Rating is a rating system developed by 3M. It rates the manufacturer’s Filtrete product line and their ability to capture airborne particles smaller than 1 micron.
FPR Rating is a rating system developed by The Home Depot for brands sold through their stores, including Honeywell. It utilizes a color code and number scale (4 to 10) that closely resembles the MERV rating.

"Third shipment was perfect Second was the wrong size First was damaged filters in an intact box Customer service was very easy to work with. Wait time on the phone for an agent was short. I had the option of replace or refund."
"we sent these filters back, wrong size"
"Filter seems to be well made. Fits my size as good as any I have found thus far."
"The Aerostar's foam top and bottom strips prevents the filter from sliding into the furnace compartment."
"The filters form, fit and function are appropriate for the application"
"The factory direct filters are good. They are less expensive than other filter suppliers. The packaging is not wrapped in plastic to protect the filters like other brands. The shipping was on time. The size fits perfect in the furnace. So far so good."
"Even though my prior filter also is listed as 16/25/5, the filters I got from you did not fit. The opening for the filter in my furnace is actually about 4 1/2 inches high, and your filter is 5 inches. Thus, it does not go into the opening. I am sure your filters are very good, but I cannot use them. Can I return them?"
