perry-air-filter-webPerry Air, EF1 1" Polarized Media Filters – The Next Generation!

Our patented filter utilizes the latest technology, with superior design and efficiency, enabling it to capture 0.3 - 0.5 micron respirable particles that can trigger allergic reactions.  Our filter incorporates a power head which only requires 24-volts to operate. When the charge created by the power head is applied to the center screen it creates an electrical field, which causes the respirable sub-micron particles to adhere to the filter pads.

Our filter includes:

  • A New, Self-locking Closure
  • Unique Filter Pads
  • U.S. Patent

WARRANTY:  The unit comes with a 3 year warranty on the frame and a 3 Year warranty on the power supply.

An In-Depth Look at Our System

The Perry Air Filtration System consists of a sturdy, hinged aluminum frame. This frame supports two stainless steel screens. Inside are two special fiber collector pads, with a central stainless steel screen separating them. The power head, which runs on 24 volts, supplies high voltage to the media via the center screen. This generates a high value electrical field which transforms the special long-strand media into a mass of polarized fibers which pull particles out of the air much like a powerful magnet attracts iron filings.

This process results in a filter that traps very small particles, including the respirable particles in the .3 - .5 micron range, while offering extremely low initial pressure drop. Maintenance is simple. Media pads typically last for 3 months. When they are loaded, unplug the 24-volt cord from the power head. Remove the filter, open it and remove the dirty media. The kit even includes plastic bags to transport the dirty pads to the garbage can. Replace the pads with new ones, close the filter frame, replace it in the system and plug the power back in. Each system comes with 4 changes of pads.


The Technology (How it Works)

Fiberglass is an electrical insulator (dielectric) that can be polarized by an electric field. When a dielectric is placed in an electric field, electric charges shift from their normal positions causing dielectric polarization. Because of dielectric polarization, positive charges are displaced toward the field and negative charges shift in the opposite direction.

Our filter induces a voltage to the center screen. The fiberglass media between the center screen and the outer screen polarizes the fiberglass molecules. The shifted electric charges within the fiberglass media provides an excellent location for oppositely charged dust particles to adhere.

The standard fiberglass filters supplied with most HVAC systems do not have the ability to remove the smallest particles. However, they do offer very low pressure drop across them. The pleated fabric filters that are available provide some small particle removal. However, they create a significant pressure drop (some, up to 50% less air flow). Our polarized media filters provide you the best of both - very low pressure drop and they remove sub-micron particles.
