THE DYNAMIC AIR CLEANERS
Clean, Healthy, Fresh Air For You and Your Family
1“ Polarized-Media Electronic Air Cleaners
Combining ease of installation with low static pressure (for lower energy consumption and system wear), 1“ Dynamic Air Cleaners are high-efficiency whole-house electronic air cleaners with an equivalency rating of MERV 13. As tiny sub-micron particles and volatile organic compounds (VOCs) pass through the central heating and cooling system, they become polarized. The polarized particles get larger as they join together with other polarized particles and collect on a disposable low-static polarized media pad with an activated charcoal center screen. Dynamic
Air Cleaners remove difficult odors and provide an efficiency of 97% for particles down to .3 microns in size. 1“ panels fit directly into existing filter racks or filter grilles and are powered using simple 24V wiring connected to the central HVAC system.
What’s MERV?
MERV, or Minimum Efficiency Reporting Value, is a number from 1 to 16 that is relative to air filter efficiency. The higher the MERV value, the more efficient the air filter is at removing particles. At the lower end of the efficiency spectrum a fiberglass panel filter may achieve MERV 4 or 5. At the higher end, filters that achieve MERV 13 or 14 are typically used in hospitals and clean rooms. High MERV filters are capable of removing higher quantities of extremely small contaminant (particles as small as 1/300 the diameter of a human hair). Higher MERV ratings can create problems with greater airflow resistance. This is also referred to as static pressure. With most filters the filter media becomes denser, and static pressure increase, as the filter efficiency increases. Increased static pressure forces the system fan motor to work harder as it pushes air through the filter. This also increases energy consumption. So for optimum performance, consumers should select the highest efficiency filter with the lowest static pressure.
What’s a micron?
Particle size is usually measured in microns, a metric unit of measure. A micron is 1/25,000 of an inch. There are over 20 million particles in the average cubic foot of indoor air.
Approximately 98% of all particles (by count) are in the size range of 5 microns or less. Visible particles represent only a small fraction of particles found in indoor air.

The Dynamic Advanced PCO System
The Dynamic Advanced PCO System destroys pollutants using ultraviolet light in a three-step process. First, the pollutant adsorbs to the surface of the catalyst. The pollutant and catalyst are then exposed to the photons of UV light. The light energy activates the catalyst, which breaks down the pollutant into nontoxic products. Odors and VOCs are vaporized by the UV light in much the same way that a drop of cold water is vaporized when it drops into a hot skillet. Advantages of PCO include:
 No Ozone
High destruction efficiencies at room temperatures
High oxidation yields for gas phase reactant and odors
Complete oxidation of organics to CO2 and H2O
Long service life with low maintenance requirements
Negligible pressure drop in duct system
Easy to install
The TiO2 PCO catalyst module is constructed using dual titanium dioxide metal catalyst screens that are pleated to provide additional surface area. More surface area means higher efficiency. The screens are permanently mounted to a module that mounts directly to the HVAC system plenum or ductwork. A square 3“ opening is required and a depth of at least 14“ into the plenum.
The high output UV/PCO lamp slides into the PCO catalyst module between the dual catalyst screens and easily mounts to the catalyst module. The 24V ballast is external to the unit to provide flexibility and ease of wiring.
How PCO works
Photo-catalytic oxidation (PCO) is an efficient means of eliminating airborne gas-phase contaminants. PCO technology utilizes ultraviolet light to promote electrons from the valence band into the conduction band of a titanium dioxide semiconductor. Destruction of organic compounds takes place through reactions with molecular oxygen or through reactions with hydroxyl radicals and super-oxide ions. Photo-catalysis does not require extreme temperatures to be effective, and the titanium dioxide material used in many PCO reactors can be incorporated into existing HVAC systems without adversely impacting the system static pressure.
The Dynamic Advanced PCO System consists of a high intensity UV-C ultraviolet lamp (254nm) and a Titanium Dioxide catalyst module. When exposed to ultraviolet light, the photo-catalyst becomes highly reactive and attacks the chemical bonds of VOCs and bio-aerosol pollutants, thereby reducing gaseous products and biological contaminants to carbon dioxide (CO2), water vapor (H2O), and benign mineral acids.
