Each filter includes 1 charcoal panel filter insert. Replacement inserts are sold in 4-packs.


Get dual action air cleaning relief from both airborne particles such as dust, pollen, and mold, plus adsorb noxious odors and fumes from tobacco smoke, cooking, pets and cleaning products. Requires no more space than an ordinary furnace filter, it’s two air filters in one.  

The DustPlus air filter contains a woven synthetic front panel, which carries a permanent electrostatic charge to attract and hold airborne particulates. The interchangeable back panel (afterfilter) consists of activated carbon media, which adsorbs noxious odors/fumes. Depending on odor and fume levels, this panel should be changed every 3-4 months in the average household.

• Washable electrostatic prefilter for particulate removal

• Disposable 1/4” thick activated carbon panels sold in 4-packs for odor/fume removal (replacement panels available in the drop down menu above)

• Galvanized steel frame with wire reinforcement opens & closes for easy back panel replacement

• Exclusive ACCUMULATOR CHAMBER® design for maximum performance

• Lifetime warranty on permanent parts only, warranty does not include activated carbon

• UL Classified as to Flammability Only


How the Accumulator Chamber® Works

Utilizing two electrostatically charged fabric panels separated by our unique Accumulator Chamber produces a very effective three-stage air filtration process for residential applications. The first air filter media panel (the prefilter) attracts and holds airborne particulates. The filter fabric’s inherent electrostatic charge enhances filtration by drawing particulates onto fiber surfaces like a magnet. Static electricity does not discharge over time because the air flow helps it maintain the charge – nor does it require insulation or grounding. When particulates build up on the DustPlus’s prefilter, airflow forces them to break off and collect in the Accumulator Chamber, where turbulence and electrostatic forces cause agglomeration into even larger particulates. These agglomerated particulates are too large to pass through the second panel (the afterfilter).

DustPlus’s activated carbon afterfilter attracts and holds the smaller particulates that may have escaped the prefilter, or particles that do not respond to an electrostatic charge.

DustPlus Literature



Disposable activated carbon panel filter is highly effective for removing organic odors. Framed in galvanized steel frames in 1/8” to ¼” thicknesses. Synthetic media (100% nonwoven polyester) is impregnated with finely ground, highly porous coconut shell based activated carbon, and heat set to retain those coatings even when the media is rinsed or vacuumed.

Activated carbon panels can be used alone, or as an afterfilter within the DustPlus® 1” furnace air filter or electronic air cleaner prefilter/afterfilter upgrade kit. DustPlus afterfilters do not require a wire mesh stabilizing layer as the reuseable main frame already contains one. Stand alone carbon panels or electronic air cleaner afterfilters require a wire mesh stabilizer.

• Initial Airflow Resistance: 0.14 in. w.g.

• Average Arrestance Efficiency 81%

• Dust Holding Capacity 80 grams

• 15.1 grams carbon per square foot of nonwoven polyester media

• U/L Classified as to Flammability Only


A note about washable filter frame thickness:

All washable filters have the same amount of filtering media no matter the thickness of the filter frame. The frames are available in many sizes to allow users to install the filter into varying widths of tracks, slots, grilles, etc. This eliminates the need for modification of the track/slot/grille/etc. when switching from one type of filter to another, i.e. switching from a 2" thick pleated filter to a washable filter. All washable filters must be washed monthly; so they are made with enough media to work as designed and allow for proper dust holding capacity until the monthly wash is required. A thicker frame on a washable filter does not contain more media nor is the media doubled up or thicker in any way. The advertised efficiency and air flow remains the same throughout all thicknesses of washable filters in each of their respective LxW dimensions. In filtration, the efficiency is the particle size a filter will capture.
