At Filterbuy, we take pride in being a one-stop shop for all of your air conditioner, furnace, or HVAC system filter replacements. We offer hundreds of custom sizes in various filtration ratings to ensure that you can find the perfect fit for your specific needs. Our goal is to provide you, your family, and your community with clean indoor air, allowing you to live and breathe freely.

What sets our products apart is their premium features. Our filters have a pleated, electrostatic design that captures more particles, providing an enhanced filtration experience. Additionally, they have a reinforced beverage board frame that can withstand extreme temperatures.

The problem we solve is that we allow customers to easily purchase the exact filter size they need from the comfort of their own homes. We also have a robust supply chain that enables us to deliver these custom sizes quickly and at no extra cost.

We love what we do because we have the opportunity to contribute to the health of our community. Our 20x20x1, 16x25x1, and 20x25x1 air filters come in convenient 4-packs, ensuring that you always have replacements on hand.

In terms of filtration ratings, we offer:

• MERV 8 Air Filters: These provide standard protection (90%) and are perfect for homes or businesses that want good indoor air quality at a reasonable rate.
• MERV 11 Air Filters: These offer superior protection (95%) and are ideal for homes or businesses with factors such as pets, smokers, and allergy sufferers.
• MERV 13 Air Filters: These provide optimal protection (98%) and are perfect for larger homes or businesses that want the best possible filtration experience.
• MERV 8 Air Filters with Activated Carbon: These are odor eliminators (90%) and combine reliable MERV 8 quality with activated carbon to inhibit unpleasant smells.

Our website allows you to easily add these filters to your cart for purchase. We have received positive reviews from our customers, with an average rating of 4.5 out of 5 stars.

Our prices range from $50.52 to $53.42, depending on the specific size and filtration rating. We offer different package quantities and recommend different filters based on your needs, such as standard filtration, superior filtration, or optimal filtration.

To ensure you choose the correct filter size, we provide information on nominal size versus actual size. We also offer guidance on how to measure your air filter if the dimensions are not listed on the frame.

Regularly changing your air filter is crucial for maintaining a healthy lifestyle and preventing respiratory ailments. We recommend replacing your filter every 90 days, although this may vary depending on factors such as filter size, pet ownership, allergies, and the presence of children.

Most of our filters are universally compatible with various systems, but it's important to match the specific brand name on a listing with your unit model to ensure compatibility.

The number of air filters you need depends on your specific situation. We offer package quantities ranging from 1 to 12 filters to accommodate different needs.

Changing your air filter is a simple process. Once you find the right size, turn off the power supply, remove the cover from your intake vent, and take out the old filter. Insert the new filter in the same direction as the airflow, replace the cover, and turn the power back on.

At Filterbuy, we are passionate about providing better air for all. We believe that everyone deserves access to clean indoor air, free of allergens and pollutants. Our variety of expert services and custom air filter sizes ensure that we always have the perfect fit for your home or business.

Our new green frames symbolize the peace of mind that comes from knowing your environment is cared for. These frames are made with the same high-quality materials as our previous ones.

We are proud to be 100% American made. Our business has grown since 1958, and we now have manufacturing locations across the United States. This allows us to efficiently fulfill custom orders and deliver them directly to households and businesses at premium rates.

To simplify the filter changing process, we offer a subscription service. Once you find the right product, you can choose the delivery interval, and we will ensure that your filters arrive on time. Subscribers also receive a discount on every delivery.

As a small, family-owned and operated company, we have a long history of giving back. We prioritize community investment and personal aid in every possible opportunity.

Our 16x20x4 replacement air filters are designed to fit furnaces, air conditioners, heat pumps, and HVAC systems. They have a MERV 11 synthetic media that traps 95% of airborne particles without impacting air flow. These filters are electrostatically charged, pleated, and 100% manufactured within the United States. The industrial grade beverage board frames with dual wire backings improve durability and outperform standard designs made of cardboard.

If you receive items with a different label, frame, or media than what is pictured, please note that any such alteration is purely cosmetic and your filter will still function exactly as described.
