The PD-900DW Duct or Wall Mount HEPA Air Purifier
The 5-in-1 Portable HEPA Air-Purifier offers the ultimate in air filtration and sterilization
This patent pending combination uses HEPA, UVC Germicidal Light non ozone producing) and Photo Catalytic Oxidation. It removes and destroys allergens, lung damaging atmospheric dust, biological, chemical contaminants, odours and more. Ideal for residential and commercial applications as well as manufacturing, processing plants and more.
PD-900DW: 5 Stage Filtration
Carbon Pre-Filter
The PD-900DW goes beyond trapping particles—it neutralizes them. The UVC Lights provide powerful germicidal protection by neutralizing bacteria, viruses, and mold spores at the DNA level. Unlike traditional filters, they sterilize rather than trap, delivering biological disinfection for healthier indoor air. Installed inside air purifiers, these lamps stop pathogens from reproducing and spreading. With a lifespan of up to 13,000 hours (2–3 years), UVC technology adds an extra layer of safety, making it indispensable for spaces where infection control is a priority.
99.97% True HEPA Media Filter
The Photo Catalytic Oxidation (PCO) Filter uses a UV-activated titanium dioxide catalyst to break down VOCs, bacteria, viruses, and stubborn odors into harmless water vapor and carbon dioxide. Operating at the molecular level, it doesn’t just trap pollutants but destroys them, offering deeper purification than standard filters. With a lifespan of up to 13,000 hours (about 2–3 years), the PCO filter is a powerful technology for homes, offices, and healthcare facilities demanding advanced IAQ protection.
Dual UVC Germicidal Lamps

With a lifespan of up to 13,000 hours (about 2–3 years), the PCO filter is a powerful technology for homes, offices, and healthcare facilities demanding advanced IAQ protection.
Potassium Permanganate Carbon Filter
Specially engineered for gas-phase filtration, the Carbon Potassium Permanganate Filter eliminates VOCs, formaldehyde, sulfur compounds, and light gases that standard carbon filters cannot fully neutralize. By combining activated carbon with potassium permanganate, it enhances adsorption and oxidation for maximum pollutant removal. Operating at the molecular level (0.001–0.01 microns). This filter ensures exceptionally fresh air., this filter maintains air purity for 1–2 years before replacement. It is a vital component in multi-stage purification systems that go beyond basic odor removal.

Airborne viruses, such as those that cause colds, flu, and COVID-19, spread through respiratory droplets and can cause serious illness.
Airborne bacteria can cause infections and illnesses, spreading easily in crowded or poorly ventilated spaces.
Pollen from plants is one of the most common indoor and outdoor allergens, often responsible for hay fever and seasonal allergies.
Pet dander consists of tiny flakes of skin from cats, dogs, and other animals, and it is a common indoor allergen.
Airborne fungi, commonly found in soil and damp buildings, can cause infections, allergic reactions, and toxic mold-related illnesses.
Dust and lint, originating from textiles and household activity, are nuisance particles that may worsen allergies and asthma.
Radon is a naturally occurring radioactive gas that seeps from soil and rock; it is the second leading cause of lung cancer after smoking.
Volatile Organic Compounds are emitted from paints, cleaning agents, and solvents, and they can severely impact respiratory and neurological health.
Ethylene is a natural plant hormone and industrial gas that, at high concentrations, causes dizziness and respiratory irritation.
