The 470140 is the 15 7/8 inch x 15 7/8 inch x 2 inch replacement HEPA filter for the PremierOne HEPA 300 Whole House Air Cleaner.
A filter must collect 99.97% of a specific particulate that measures 0.30 microns, in a test established by the Institute of Environmental Science in order to receive the HEPA filter designation. The PremierOne 470140 HEPA filter can capture 100% of all particulate sizes ranging from >100 microns down to 0.01 microns.
Combined with a pre-filter to capture larger particles, the PremierOne 470140 HEPA filter is designed to maintain its performance rating for up to two years before replacing the HEPA filter.
