EPA data shows most homes suffer from either: 1. Inadequate Ventilation, 2. Indoor Generated Pollution, or 3. Outdoor Air Pollution. Studies now link the air we commonly breathe to respiratory and cardiovascular diseases, increased hospital admissions and impaired cognitive functions [1]. We spend 90% of our time indoors so clean indoor air is one of the best health investments we can make. 

Benefits of clean indoor air...

  • Reduce sick days 
  • Improve cognitive skills [1] 
  • ​Asthma and Allergy Relief 
  • Better sleep - whisper quiet clean air, all night for easy breathing
  • Cleaner home - less dust on surfaces
  • Mould and Condensation prevention     
  • Reduce respiratory and cardiovascular health risks

1) True HEPA Grade Air Quality

​PM1, the sub-micron particles commonly found in smoke, smog & traffic fumes are the most harmful airborne particles of all. To remove them from indoor air requires a proper HEPA filter and a large air flow rate.

Sanctuary Air uses  extra-large sized medical grade HEPA filters​ to allow the free passage of air, removing PM1 at an air flow rate that overcomes continuous re-contamination from both indoor and outdoor air pollution sources, so that true HEPA grade air quality is sustained in your premises. This is great news if you live near a busy road or in a smoky neighborhood.​

​​​​​​​​FAQ - whole-house air purifiers

What is PM1?

PM1 refers to sub-micron particles. It is the size of PM1 particles that make them most harmful - small enough to pass the defense of our lungs & alveoli and enter into our bloodstream, damaging cardiovascular tissue and the inner walls of arteries. Once in the blood stream, PM1 can migrate into other organs including our heart and brain. PM1 is largely generated from road traffic exhaust, and smoke from industrial processes, wood heaters and tobacco. A HEPA filter is necessary to efficiently capture PM1.

Why include outdoor air in the purifier's air intake?

Air purifiers are very efficient at reducing airborne pollutants, such as fine particulates, VOCs and odours. On the other hand, air purifiers can not replenish Oxygen and can not remove trapped indoor moisture, exhaled CO2 or CO from gas appliances. A total clean air solution must include sufficient ventilation. There is no alternative.

Older buildings may have sufficient natural ventilation but with modern air tight construction many buildings suffer from inadequate ventilation particularly during calm weather. Stagnant indoor air is concentrated in synthetic chemicals and particles from carpets, glues, paints, cleaning fluids, sprays etc.

To introduce ventilation air into the air purifier's intake is highly advantageous because
a) Ventilation air can be controlled at the correct rate to suit your building and its number of occupants in accordance with AS/NZS 1668.2-2002, independent of weather conditions
b) Ventilation air is cleaned before it enters your building, removing smoke, smog, dust etc. Far superior than cleaning polluted ventilation air after it enters the building.
c) Positive pressure is generated indoors because the purifier supplies more air than is sourced from indoors. Mild indoor air pressure acts as a shield against uncontrolled infiltration of dusty and polluted outdoor air.

The result is truly outstanding indoor air quality and a home/office that requires less cleaning.​

How does cleaner air improve cognitive skills and increase productivity in study and work ?

Indoor air is polluted with hundreds of volatile organic compounds (VOCs) from construction materials, furnishings, office equipment, cleaning products, carpets etc. Indoor air is also polluted with excess CO2 and CO from human respiration and from indoor combustion, for example from gas appliances. It turns out that even at commonly experienced levels, VOCs and CO2 have a very significant affect on cognitive functions.

A 2015 double-blind study[1] measuring nine cognitive domains, found that people who work in offices with reduced levels of indoor VOCs and CO2 on average score double those who work in offices with typical pollutant levels. Crucially, participants scored 131%, 288% and 299% higher respectively in the key areas of crisis response, strategy and information usage. Usha Satish, professor, SUNY Upstate University states  "these are critical decision making parameters linked to optimal and productive functioning". Joseph Allen, assistant professor, director of the Healthy Buildings Program at the Harvard Center for Health and the Global Environment, states “These results suggest that even modest improvements to indoor environmental quality may have a profound impact on the decision-making performance of workers.”

The concentration of VOCs and CO2 does not have to be abnormally high; even modest levels affect our cognitive skills. Today, buildings with reduced VOCs and CO2 levels, known as High IEQ (Indoor Environment Quality) buildings are highly sought after and attract premium rent from business.

A good room air purifier with a large carbon filter can address VOCs in one room but if you want to address both VOCs and CO2 (and in every living space), you'll need our whole house air purifier which includes an outdoor air intake.

Why do some salesmen claim whole house air purifiers don't work?

It's nonsense that originated from one US company, with the intention of selling you their portable air purifier. It is not supported by evidence. It's like saying "central ducted heating doesn't work" without recording air temperature.​

 Whole-house systems have a huge air quality advantage over portable air purifiers:

  • multiple rooms can be cleaned simultaneously 
  • ventilation air can be included in the air intake to generate positive pressure
  • the fan can run at maximum speed without the intrusion of noise.

There is nothing better than a HEPA grade whole house air purifier - easily demonstrated by air quality measurements with a laser particle counter.


What filters do your air purifiers use?

We use reliable "Mechanical" filters. Airborne pollutants are physically captured and remain trapped in the filter without producing any chemical by-products or ozone.

HEPA filters capture fine and ultra-fine particles. Our top HEPA filter is rated medical grade H13 (it is almost rated H14) This filter removes harmful PM1 particles and any smoke.​ To capture odours and hundreds of volatile chemical gases (VOCs), we use broad spectrum activated carbon. 

Sanctuary Air filters are large in size to extend replacement intervals and reduce ownership costs. Long filter life also adds the convenience of extra low maintenance. 

For more information about our filters please link to our Replacement Filters page.

Where do I purchase replacement filters?

Our purifiers use standard sized professional filters; the same type as used in hospitals, museums and premium public buildings. These are serious no-nonsense filters. They can be purchased directly from us or we can direct you to your nearest professional filter supplier.

The CADR rating system is used to compare the performance of portable air purifiers. Why doesn't it apply to whole house air purifiers?

CADR (Clean Air Delivery Rate) is determined by a standardised test that calculates the maximum room size in which a portable room air purifier (on maximum fan speed) can achieve 80% reduction of airborne particles. The 80% target requires the room air purifier to deliver 5 clean air changes per hour in that room size.​ The CADR test doesn't apply to whole-house systems because:

1) Every Home is different

2) Portable purifiers need to overcome a higher pollutant load per room due to airborne particles that infiltrate from adjacent indoor spaces, whereas with a multi-room ducted system the adjacent spaces are also being cleaned, so the pollutant load is reduced.

3) A whole house system has the option of adding ventilation air to the air intake. Doing so introduces positive pressure and a powerful performance boost.

4) Whole house systems have a more effective air flow pattern. In the case of portable purifiers, air flows in a shorter circuit because the inlet and outlet are in close proximity and within the same room; some already clean air is drawn back to the purifier before completely mixing with room air, meaning the purifier has to move more air to remove contaminants. In contrast, a ducted system has multiple outlets that are well separated from the air intake and are in separate rooms. Air is well mixed by time it reaches the air intake, meaning a ducted system will collect more contaminants per unit volume of air moved.

In essence, whole house systems have distinct advantages over portable air purifiers and will achieve significantly greater than 80% reduction with 5 air changes per hour. Normally, just 3 air changes per hour will achieve outstanding results. With the addition of ventilation air and positive pressure, a whole house system will take air purity even further, to a level that is difficult to achieve with portable air purifiers.
