We stock every Dynamic Air Cleaner filter media made. Order from the source of Dynamic Electronic Air Cleaner filters and parts just like the contractors do. Dynamic Air Cleaners use electronic polarized-media technology to provide maximum ozone-free air cleaning, while installing quickly into the existing filter tracks of your central heating & cooling system. Dynamic 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. Dynamic 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. Remember to replace your Dynamic Air Cleaner filter media every 30 days for the best performance you can achieve.
