NOTE: White Yellow or Blue coloring of pads is simply different dye colors. There is no difference in performance or quality

These Dynamic Sales HVAC replacement filter pads utilize a full sheet of activated carbon inserted between two sheets of fiberglass media, giving it the ability to be installed in any direction since the power-head probe will always contact the full sheet of activated carbon.

The original MicroGuardian AirScrubber III filter pad may have a target painted on it. Since the manufacturer chose to use a cheaper Carbonized mesh rather than a full sheet of carbon, like the Dynamic Sales HVAC, they had to add a piece of foil as a target so the electrode would touch the foil and electrify the pad. No worry with the Dynamic Sales HVAC brand replacement pads, you can load them any which way they fit and you will be sure to have a secure contact with the carbon sheet for optimal distribution of the electrical current.

MicroGuardian AirScrubber III Air Cleaners use electronic polarized-media technology to provide the maximum in air cleaning, while installing quickly into the existing filter tracks of your central heating & cooling system.  Air Cleaners are ideal for removing odors as well as the smallest sub-micron particles, airborne pathogens, and volatile organic compounds (VOCs).  Electronic polarized-media technology is non-ionizing which means no Ozone is produced

MicroGuardian AirScrubber III Air Cleaners trap 97% of particles at .3 microns and continue trapping particles much smaller in size.  Unlike passive mechanical filters where the size of small holes in the material determines the size of particles that can be captured, electronic polarized media employ the principal of agglomeration to join polarized sub-micron particles and VOCs to each other as they pass through the central heating & cooling system.  As the particles get larger during subsequent passes, they collect on the air cleaner’s disposable replacement media pads.  Over time, even the smallest particles --- those we breathe---are removed from the air.

 ·         Superior filtration traps germs, bacteria, viruses, and allergens better than Merv 11 media filters. Unlike electronic precipitators, effectiveness does not diminish over time.

·         Removes cooking, grease and tobacco smoke from the air.

·         Easy maintenance: Simply replace economical filter pads as needed.


How does it work?

When particles such as dust, pet dander and household chemicals pass through the filter, they become polarized. These polarized particles join together to form bigger clusters that are more easily captured and collect on the fiberglass pad with an activated carbon center screen. The activated carbon center media pad is a non-woven polyester base fabric. The carbon media is UL certified for flame retardancy, class 2. The fiberglass media becomes polarized by the charge from the power supply and acts like a powerful magnet to attract sub-micron particles.
