Post-Filter Improves E1 Capture 8%

To remove the finest E1 particles, the new Honeywell postfilter utilizes the residual charge on particulate. Particles passing through the honeycomb are pulled to the walls by static charge and trapped in the grooves. A patented open channel weave minimizes resistance to air flow while effective in capturing submicron particulate.

The photo below shows the intricate groves in the walls of the honeycomb. Antimicrobial coated. Photo magnified 6x.

Post-Filter Compatibility

Postfilter Compatibility comparisonHoneywell post-filters improve cleaning efficiency without reducing the air flow through your air cleaner, minimizing the strain put on your central air system.

Honeywell post-filters slide in to any F300A F300E F50F F58F. These models are shown in the photo at the top-right and are identified by having a full length power box. These models have been in production since 1994.

These Post-Filters will NOT fit the earlier F50A or F50E models. These models have a short power box see lower-right photo.

Post-Filter Inspection

Honeywell Eviclaire InspectionThe photo shows a 6 month old post-filter. The clean strips align with the air that passes closest to the ionizing wires.

Inspected up close, the dirty areas are a deep stain. Vacuuming would clean the surface lint but the fine E1 particulate becomes infused like a smoke stain. Honeywell notes the postfilter will loose its static properties if washed.

Inspect your old postfilter. It will begin to collect a layer of dust or lint if cell cleaning is overdue. The postfilter wills also show problems such as a missing ionizing wire.
