The Filterbuy replacement air filter 18x20x1 (actual measurements: 17.50" x 19.50" x 0.75") ensures that your furnace, air conditioner, heat pump, or HVAC system is circulating the cleanest air possible to help preserve your budget and healthy lifestyle. MERV 11 synthetic media (comparable with Micro Allergen Defense MPR 1000 - 1200 & FPR 7) is recommended if you have pets or allergies due to its capability to trap 95% of airborne particles, protecting your home or business from smoke, smog, debris, lint, pollen, mold, dander, and other forms of dust without impacting air flow. High quality construction features an electrostatically charged design with 14 pleats per foot that captures more harmful particles and prolongs the products lifespan by three times that of fiberglass models. Plus, our industrial grade beverage board frames are paired with dual wire backings that significantly outperform traditional cardboard compositions by improving structural integrity with their ability to endure temperatures up to 200 degrees Fahrenheit and withstand exposure to moisture. Installation is also made simple with the addition of easy-to-understand arrows that help identify the direction of air flow and subsequently the way the filter needs to be placed. To top it off, all our components are 100% manufactured within the United States and designed with recyclable materials, providing an eco-friendly alternative to enhancing your air quality.

I love my new filters. They are so much better than my old ones. I don't have to change my filters every month, but every three months. The air quality is so much better. Try them for your self, you can't go wrong. Thanks, so much!

I love my new filters.

Filterbuy

It was so nice to finally fine a place to purchase my hard to find size for my unit. No more going from store to store only to find they didn't carry the size I needed anymore. I picked up the phone called in the size and 2 days later it was at my front door. Perfect so glad I found this store. Thank you!!

It was so nice to

For years, I thought, "Find the best price on the filters for your furnace and go with that. " Today, I have a much different outlook. You would think that someone who suffered from allergies to pollen and everything outdoors as a child would have a greater understanding of the importance of filters. It wasnt until we purchased our new home with a Trane heat pump that we realized the warranty required that you use certain filters in your heat pump. When we started using them, I noticed my husband and I were not sneezing or coughing as much as before.At that moment, I realized the difference a filter can make. We often think were saving money by using lower-priced filters when, in fact, were costing ourselves more money by causing the furnace or heat pump to break down quicker by using inferior filters. When the filters are not changed regularly, they make your furnace work harder, not to mention the particulars that the filters dont pick up that go into the furnace/heat pump. What doesnt blow into your home stays in the vents. It gathers on the motor and various parts and will eventually cause it to break down earlier than it would if we used the best filters we can afford.We live in a deeply wooded area, and we change our filters monthly in the spring and fall due to the amount of dust and pollen. We love the filters we get from FILTERBUY. They come directly to our home. What could be easier than that?

What a difference a filter makes!

Very pleased with this company and have placed many orders with them.

Reliable Company + Great Products

Overf the years your filters have proven to work just fine.

Solid

Serves the purpose it is designed for at affordable price.

Serves the purpose it is

I just want you to know that your marv-11 was the perfect filter. My mother in law lives with us and she couldn't quit snezzing, and had a runny nose. Thanks to you no more, she is enjoy her food much better, and truly breathing better.

mfg spec furnace did not match 18x20x1 filterbuy spec - contacted them , no issue . Making up custom order correct size. Nice people to deal with from start to finish.

i orered worong size- fixing no issue and delay

Buying experience was fast and easy. Only downside is that filters were received not individually wrapped. Im not sure if thats an error or due to buying a higher quantity than I have in the past but it would be nice for filters to be individually sealed until time of use.

Not individually wrapped

The 18 x 20 is a hard size to find and in the past I have had to resort to cutting a 20 x 20 down to size which is not the greatest option. The filter appears very well constructed. Service was excellent

The 18 x 20 is
