These advanced True HEPA air cleaners integrate directly into your home’s return duct, quietly capturing particles, gases, and odours across a tightly sealed, multi-stage filtration system. With each unit diverting ⅓ to ½ of return air through its filters, homes can achieve up to 67 complete air changes per day, depending on model and square footage. They are ideal for households dealing with allergies, pets, smoke, cooking odours, mustiness, or anyone seeking cleaner, healthier air year-round.
PD-HEPA350: 3 Stage Filtration
True HEPA Filtration

True HEPA Filtration (Cylindrical or 6″ HEPA Core)
True HEPA filtration is the heart of every PD-HEPA system—engineered to capture 99.97% of particles 0.3 microns and larger on first pass. As the filter loads with particulate, its efficiency increases, allowing it to capture particles as small as 0.001 microns. This deep-pleated, high-surface-area design removes dust, allergens, bacteria, viruses, mold spores, smoke, pet dander, and more, providing continuous whole-home protection and healthier, fresher air.
Carbon Prefilter Blanket

Carbon Prefilter Blanket
The carbon prefilter serves as the system’s first line of defense, capturing lint, hair, larger particulate, and nuisance debris before they reach the HEPA core. This extends the HEPA filter’s lifespan while simultaneously absorbing common household odours from pets, cooking, and musty spaces. Its lightweight design promotes high airflow with low resistance, ensuring strong CFM output and maintaining system efficiency—particularly important for homes with active lifestyles, pets, and regular indoor traffic.
Carbon VOC After Filter (Standard on PD-HEPA550-3)
Buy Filter
Carbon VOC After Filter(Standard on PD-HEPA550-3)
The Carbon VOC After Filter provides advanced odour and gas reduction by targeting volatile organic compounds (VOCs) released from paints, cleaning products, glues, finishes, and everyday household materials. Its high-adsorption carbon media captures these chemical gases at a molecular level, creating a fresher, healthier indoor environment. For families sensitive to chemicals or experiencing lingering odours, this stage delivers a meaningful improvement in comfort and perceived air quality.

Tobacco Smoke
Tobacco smoke contains a mixture of toxic particles and gases that are directly linked to lung cancer, heart disease, and serious respiratory illnesses.
Particulate Matter (PM2.5)
PM2.5 originates from traffic, industry, and wildfires; these fine particles penetrate deep into the lungs, enter the bloodstream, and damage the heart and lungs.
Asbestos
Asbestos fibers, once used in insulation and tiles, are dangerous when inhaled and can cause lung cancer and mesothelioma.
Lead (in dust)
Lead dust, often from old paint or industrial sources, is highly toxic, particularly to children, and damages the brain and kidneys.
Molds and Mildew (spores)
Mold and mildew spores thrive in damp areas, and inhaling them can trigger allergies, asthma, and chronic respiratory problems.
Fungi
Airborne fungi, commonly found in soil and damp buildings, can cause infections, allergic reactions, and toxic mold-related illnesses.

Why your indoor air quality is so important
Reduces Allergens & Triggers
Pollen, pet dander, mold spores, and dust mites are common indoor allergens. Good IAQ helps minimize flare-ups for allergy and sinus sufferers.
Eliminates Harmful VOCs & Chemicals
Indoor environments often contain volatile organic compounds (VOCs) from paints, cleaning products, building materials, and furniture. Purified air removes these invisible but harmful toxins.
Controls Odors
Air purification eliminates persistent odours from cooking, smoking, pets, garbage rooms, and even industrial processes like cannabis production.
Creates a Healthier, More Comfortable Living & Working Environment
Clean air makes homes, offices, schools, healthcare spaces, and commercial facilities feel fresher, safer, and more welcoming every day.
Limits Spread of Viruses & Bacteria
High-quality filtration and UV disinfection can reduce airborne pathogens, lowering the risk of colds, flu, and other infectious diseases spreading indoors.
Protects Respiratory Health
Clean air reduces exposure to dust, allergens, smoke, and fine particulates that can inflame the lungs and aggravate asthma or chronic respiratory conditions.

PUR Distribution Air Purifiers – FAQ
Does the PD-HEPA system replace my furnace filter?
No. Your furnace filter still protects the HVAC equipment. The PD-HEPA system runs in parallel to deeply clean the air using HEPA and carbon technologies that a furnace filter cannot match.
How often do the filters need to be replaced?
HEPA cylinders last 2–5 years depending on the model, while carbon prefilters and VOC filters are replaced every 3–12 months. See the Maintenance section for details by model.
Will this help with allergies or asthma?
Yes. The system removes fine particulates, allergens, dander, mold spores, and bacteria—dramatically reducing common irritants that trigger symptoms.
Can the system be installed in any home?
Yes. These units mount to the return duct and include a plug-in power cord. They can be floor, wall, or ceiling mounted, and fit most residential HVAC systems.
