Improve Efficiency and Reduce Cost
An Aerostar furnace air filter helps keep your HVAC unit working efficiently by removing dirt and reducing strain on the motor. When your unit runs properly, it consumes less energy, requires less maintenance and will have a longer life. These factors will have an impact on your utility bill and maintenance costs. It is recommended that you change the filter every 60 to 90 days during normal times of year but increase frequency to 30 days during peak summer and winter months when your unit is working the hardest.

About MERV, MPR and FPR Rating
The three rating systems were created by different organizations. MERV is the domestic and international Industry Standard rating system established by the American Society of Heating, Refrigerating, and Air Conditioning Engineers. The other two rating systems were created by 3M and The Home Depot, but all are rating the same filter.
MERV Rating (Minimum Efficiency Reporting Value): As you have already learned, the 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 (Micro-Particle Performance Rating): 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 (Filter Performance Rating): 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.
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.

"The filters are fine however they were shipped in a box that was too big. The filters ended up getting mashed at one end because they were loose."
"Excellent. On line ordering was easy. Delivery was really fast. I have used these for some time now and I am very pleased with the product."
"Most filters I’ve bought in this size don’t work. They are a fraction of an inch too large. This one is perfect!"
"Good product, good price. Repeat customer"
"The filter upgrade from 1 inch to 4 inch fit great. The quality was good and the shipping was fast. I will be ordering more. Thanks"
"I return to FDF after competitive pricing options and buy as FDF has very competitive pricing, fast shipping and an efficient, easy to. Use web site. Thank you!"
"The ease of the site was great. Received the filters quickly, and item was identical as advertised."
"Filters are exactly as ordered and are performing as expected. Pricing was less than 1/2 of the local store."
"We have very odd shaped HVAC Vents and I have really bad allergies on top of being immune compromised. I absolutely love these filters and change them out every 6 months. They are better than what you can get anywhere else. When I bought a new AC Unit they offered me new filters but quickly realized that mine were of better quality. In the long run this is worth it."
"Good fit"
