This helps us achieve our goal of providing you, your family, and your community access to clean indoor air, enabling you to live and breathe freely.

Our products are unique in that they feature premium characteristics, including a pleated, electrostatic design that captures more particles and a reinforced beverage board frame capable of withstanding extreme temperatures. This enhanced filtration experience sets our offerings apart.

We solve the problem of making it easy for customers to purchase the exact filter size they require from the comfort of their homes. Additionally, our robust supply chain ensures we can deliver these custom sizes quickly and at no extra cost.

We love being able to provide a service that helps keep our community healthy. This is why we offer 20x20x1, 16x25x1, 20x25x1, and 20x25x5 air filters in 4-packs, catering to different needs and preferences.

The Minimum Efficiency Reporting Value (MERV) rates the ability of filters to trap particles on a scale of 1-20, with higher numbers indicating smaller microns captured. Our offerings include:

• MERV 8 (90% standard protection) - Perfect for almost any home or business seeking great indoor air quality at a reasonable rate.
• MERV 11 (95% superior protection) - Ideal for homes or businesses with pets, smokers, or allergy sufferers.
• MERV 13 (98% optimal protection) - Suitable for larger homes or businesses, and those who want the best possible filtration experience.
• MERV 8 with Activated Carbon (90% odor elimination) - Perfect for inhibiting unpleasant smells while providing reliable MERV 8 quality.

Choosing the correct filter size is crucial. The nominal size is a rounded number, while the actual size depicts the filter's precise dimensions. To find the right fit, measure your current filter and round up to the nearest inch.

Replacing your air filter regularly is essential for maintaining a healthy lifestyle, as old filters can lead to system defects and increased energy costs. We generally recommend changing the filter every 90 days, though this may vary based on factors like pet ownership, allergies, and the number of household occupants.

Filterbuy is committed to providing better air for all. We believe everyone deserves to breathe clean, pure air, which is why we work tirelessly to ensure you and your community have access to it. Our new, green-framed filters symbolize the peace of mind that comes from knowing your home or business is being properly cared for.
