•MADE IN MICHIGAN USA •EXCEPTIONAL QUALITY - Seal Supply brand filters perform unlike any other on the market. Our dense carbon material is interlaced and impregnated with actual carbon granules that you can see and feel. You'll notice the difference! •LAB TESTED - Seal supply brand Ultra Premium Line filters contain a minimum of 30g per sq ft carbon content rating. •UNMATCHED PERFORMANCE - Just one square foot of our product contains the carbon molecular surface area of 36,910 square yards. Equivalent to 24 football fields! •SUPERIOR TO OEM - Our filters surpass OEM specifications. Carbon is the active ingredient in your filter that scrubs your air of odors, pollutants, and particulates. So why buy cheap foreign made filters that don't even list their carbon content. •INCREASED LONGEVITY - Our high carbon content material screen more particulates from the air, resulting in less frequent replacement cycles for your carbon pre-filter and your main HEPA filter.
