We love being able to provide a service that helps keep our community healthy. We offer a range of air filters, including MERV 8, MERV 11, and MERV 13, each with its own level of filtration effectiveness. The MERV rating system measures the ability of filters to trap particles on a scale of 1-20, with higher numbers indicating better filtration.

Our MERV 8 air filters are perfect for almost any home or business that wants great indoor air quality at a reasonable rate, capturing 90% of airborne particles. The MERV 11 air filters are ideal for homes or businesses accounting for factors like pets, smokers, and allergy sufferers, capturing 95% of airborne particles. The MERV 13 air filters are perfect for larger homes or businesses and those who want the best possible filtration experience, capturing 98% of airborne particles.

We also offer MERV 8 air filters with activated carbon, which are perfect for homes or businesses that want to inhibit unpleasant smells while still maintaining reliable MERV 8 quality.

When it comes to choosing the correct filter size, it's important to understand the difference between the nominal size and the actual size. The nominal size is a rounded number, while the actual size is the precise measurement of the filter. We recommend measuring your current air filter and rounding up to the nearest inch to find the corresponding nominal size.

Replacing your air filter is essential for maintaining a healthy lifestyle, as breathing dirty air can put you at risk of developing asthma, allergies, and other respiratory ailments. We generally recommend replacing your filter every 90 days to keep your system running efficiently and your air clean, but this may vary based on your specific needs.

At Filterbuy, we are committed to providing clean indoor air for all. We manufacture our products in the USA, and our green frames symbolize the peace of mind that comes from knowing your home or business is being properly cared for. We also offer a subscription service to simplify the process of regularly changing your air filters. With our dedication to community investment and personal aid, we strive to be a trusted partner in your quest for better air quality.
