  • EXTEND THE LIFE OF YOUR AIR PURIFIER - Carbon activated pre-filters extend the life of your HEPA filter, but the air purifier as well. Pre filters prevent your air purifier from clogging up and working harder, greatly diminishing its life span.
  • OUR CARBON PRE-FILTERS ARE THICKER AND CONTAIN MORE CARBON - More carbon elements in your pre-filter means they trap more odor and dust particles. Lab tested at 30 grams per sq ft carbon content and 45 grams per sq ft total filter weight.
  • A PERFECT FIT, EVERY TIME - Seal Supply activated carbon pre-filters are machine cut with precision for an exact fit every time. Our Honeywell HPA300 compatible carbon pre-filters measure 14.2" x 17.2" x .2" (43.7cm x 36.1cm x 5mm)
  • UNMATCHED PERFORMANCE - Just one square foot of our carbon pre filters contain the carbon molecular surface area of 36,910 square yards. Equivalent to 24 football fields!
  • U.S. QUALITY YOU CAN TRUST - Seal Supply pre filters are designed, manufactured & distributed exclusively in the United States.
