AprilAire helps create Healthy Air environments with the Model 1410 16 in. x 25 in. Media Air Cleaner with MERV 11 Air Filter. This air purifier works within existing heating and cooling systems to efficiently and effectively remove dust, mold spores, pollen, bacteria, and pet dander throughout the home. The included MERV 11 air filter is 4 in. thick with a large surface area for capturing pollutants and offering superior filtration to typical 1 in. filters. (Also compatible with AprilAire 413 (MERV 13), 413CBN (MERV 13+Carbon), and 416 (MERV 16) Air Filters-not included.) Filtering out airborne contaminants helps clean the air and can lower the frequency of cleaning and vacuuming by reducing dust build up around the house. It also maximizes the lifespan of heating and cooling systems, which can become inefficient with dust and particle build up. Patented AprilAire Self-Seal Technology reduces the amount of air bypassing the filter. The included MERV 11 air filter should be replaced every 12 months, (lifespan varies for other air filter models), and it's easy to swap out thanks to the AprilAire Pure Fit Promise and patented Interlock Rail System that lets the filter slide right into place. With versatile installation options, you can install the air purifier with HVAC systems located in the basement, attic, closet, and more. The Model 1410 Whole-House Air Purifier includes a 5-year warranty and it's designed and made in the USA, meaning you can buy with confidence. Color: Silver.
