  • New postfilters have been proven to add 8-10% more efficiency at the smallest micron channel (0.3-1 microns), while keeping added pressure drop at a minimum.
  • Antimicrobial coating protects against bacteria and fungal growth on the postfilters.
  • Electrostatic charge helps attracts airborne particles like a magnet.
  • Note:The electrostatic charge will break up if washed.
  • Postfilters will elevate the performance of your air cleaner's efficiency in capturing bacteria, smoke, particles, mold spores and other fungi.
  • Replacement filters for F300 and F50F Electronic Air Cleaners only - will not Fit F50E models!
  • Honeywell recommends that postfilters be replaced approximately every six (6) months.
