Permatron air cleaner upgrade kit includes:

(Qty 1) Electrostatic pre-filter
(Qty 3) Activated carbon post-filter

Designed specifically for the White-Rodgers or Electro-Air 20 x 21 air cleaner. Each filter measures 20¼ x 21 x 5/16". This upgrade kit is for all models SST1600, SST-16, 16C26S-xxxx, 16C27S-xxxx, UST.

These filters are the full size of the air cleaner and not split in pairs like the original White-Rodgers filters. One Permatron prefilter replaces the pair of original half size F825-0337 prefilters.

Also one permatron carbon filter replaces a pair of the F825-0468 carbon filters. These Permatron filters simply side right in and do not require clips as with White-Rodgers carbon filters.

Prefilter Washing

When cleaning the prefilter be careful not to flatten down the woven foil. The aluminum weave can be easily flattened with water pressure or when cleaning with a brush. Soaking the prefilters in a tub is recommended.

See your owner's manual for washing instructions.

Electro-Static Prefilter

Metal Mesh Efficincy versus Permatron filters The Permatron prefilter significantly improves the capture of the larger 10+ micron particulate. By effectively removing this larger particulate, the collector cell more effectively captures the smaller particulate.

The improved capture of large particles will reduce the occasional spark. Also the need to wash the cells will be extended. The Permatron prefilter has a low 0.09 wg air resistance making it interchangeable with the metal mesh at 0.07 wg.

A quick cleaning of the prefilter is recommended once a month. Simply vacuum or rinse with a hose. Washing the cells would be recommended every 6 months. See brochure for more info.

Activated Carbon Filter - Odor Control

activated carbon filter removes odors and fumes Permatron's activated carbon absorbs odors and fumes. Whereas the collector cell captures particulate, the carbon captures noxious gasses.

Permatron charcoal filters exceed manufacturer specs with 14 grams of carbon per square foot along with a low 0.06 wg air resistance.

The carbon is finely ground resulting in over a million square feet of surface area. The carbon is impregnated into the filter media and heat set. There are no loose granules, the filter can be rinsed or vacuumed.

Vapors are pulled by molecular action in to tiny pores and held. In manufacturing the carbon, the activation process creates millions of micropores. The pores are sized and formulated to remove common household VOC's.

Quality Construction

Permatron rugged galvanized steel frame Permatron prefilters and carbon filters are constructed with a rugged galvanized steel frame. The frames do not easily kink or push out of square. They are not flimsy like the Honeywell brand.

The prefilter polypropylene weave is gripped solid by the steel frame. Very good quality.
Metal mesh filters can be pulled out of frame

Permatron filters are made in USA products Permatron carbon filters are made in Illinois. The foam, activated carbon, and steel frame are all products of the USA.

Permatron prefilters are also made in Illinois. The polypropylene and steel frame are products of the USA.
