Let's dive into the details of our filter offerings:

MERV (Minimum Efficiency Reporting Value) is a scale of 1-20 that rates a filter's ability to trap particles. MERV 8 filters, with 90% efficiency, are perfect for almost any home or business seeking great indoor air quality at a reasonable rate. For homes or businesses with factors like pets, smokers, and allergy sufferers, our MERV 11 filters offer 95% efficiency. For larger spaces or those desiring optimal filtration, our MERV 13 filters provide 98% efficiency.

We also offer MERV 8 filters with activated carbon, which are designed to inhibit unpleasant odors while maintaining reliable MERV 8 quality.

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

Regularly replacing your air filter is essential for maintaining a healthy lifestyle and keeping your HVAC system running efficiently. We generally recommend changing the filter every 90 days, but this may vary based on factors like pet ownership, allergies, and the number of occupants in your home.

At Filterbuy, we are committed to providing clean air for all. Our filters are universally compatible and manufactured entirely within the United States. We also offer a subscription service to simplify the replacement process, with discounts for enrolled customers.

Our company has evolved from its humble beginnings in 1958 to a nationwide leader in air filtration. As we continue to expand, we remain true to our values of community investment and personal aid, ensuring that everyone, everywhere can breathe freely.
