MERV, or Minimum Efficiency Reporting Value, is a scale from 1-20 that rates a filter's ability to trap particles of varying sizes. MERV 8 filters offer standard 90% protection, making them suitable for most homes or businesses seeking great indoor air quality at a reasonable rate.

MERV 11 filters provide superior 95% protection, perfect for homes or businesses with factors like pets, smokers, and allergy sufferers. MERV 13 filters offer optimal 98% protection, ideal for larger spaces or those desiring the best possible filtration.

Additionally, our MERV 8 filters with activated carbon are designed to inhibit unpleasant odors while maintaining reliable MERV 8 quality.

When choosing the right filter size, the nominal size is a rounded number, while the actual size depicts the filter's precise dimensions. Measure your current filter to find the actual size, then round up to the nearest inch to determine the nominal size for easier online searching.

Regularly replacing air filters is crucial for maintaining a healthy lifestyle, as dirty air can lead to asthma, allergies, and other respiratory issues. We generally recommend changing filters every 90 days, but this may vary based on individual factors.

Our filters are universally compatible with most furnaces, air conditioners, heat pumps, and HVAC systems. The quantity needed depends on your specific home or business requirements, with our selection ranging from 1 to 12 filters per package.

Changing an air filter is a simple process - turn off power, remove the old filter, insert the new one in the correct air flow direction, replace the cover, and restore power.

At Filterbuy, we champion indoor air quality as the foundation for a healthy lifestyle. We offer a variety of custom sizes to provide the perfect fit, while our new green frames symbolize the peace of mind that comes with clean, pure air. As a proudly American-made company, we are committed to delivering premium products and services to households and businesses nationwide.
