Filterbuy 14x28x1 MERV 11 Allergen Defense Air Filters (2-Pack)

The Filterbuy air filters offer a range of Minimum Efficiency Reporting Value (MERV) ratings to address various indoor air quality needs. The MERV rating system measures a filter's ability to capture airborne particles on a scale from 1 to 20, with higher numbers indicating better performance.

For standard protection, the MERV 8 filters are perfect for most homes and businesses, effectively trapping 90% of airborne particles. For superior protection, the MERV 11 filters are ideal for homes or businesses with pets, smokers, or allergy sufferers, capturing 95% of particles as small as 1-3 microns. For optimal protection, the MERV 13 filters provide the best possible filtration, capturing up to 98% of particles as small as 0.3-1 micron, making them perfect for larger homes, businesses, or medical settings.

In addition, the Odor Eliminator MERV 8 filters with activated carbon are designed to inhibit unpleasant smells, offering 90% protection against airborne particles while addressing odor concerns.

Choosing the correct filter size is important for optimal performance. The nominal size is a rounded measurement, while the actual size reflects the filter's precise dimensions. Measuring the existing filter and rounding up to the nearest inch can help determine the appropriate nominal size.

Regularly replacing air filters is crucial for maintaining indoor air quality and system efficiency. We generally recommend replacing filters every 90 days, but the frequency may vary based on factors such as pet ownership, allergy concerns, and the number of occupants in the home.
