Use this low profile 99.97% HEPA filter (stage four) to replace the worn out HEPA filter in your Quatro Air desktop mounted rhodium filter. Deep, 2" pleats efficiently capture and remove particles as small as 0.3 micron from the air. The 1/4" tick neoprene gasket ensures a proper seal with the metal filter casting. The manufacturer recommends checking and replacing this filter every 24–36 months.
This package contains one filter.
