Specifications

Purification System

1. Cleanable Pre-Filter
   Traps large particles such as human hair, pet dander and dust particles. Helps to extend the life of the HEPA and Activated Carbon filters.
2. True HEPA Filter
   Traps up to 95% of allergens and airborne contaminants down to 0.3 microns in size. These allergens include lung damaging dust, mould spores, plant spores, pet dander and pollen.
3. Activated Carbon Filter
   Neutralises odours and Volatile Organic Compounds (VOC's) such as formaldehyde and benzene, as well as other harmful fumes emitted by household products.
4. UV-C Light (254nm)
   Inactivates microbes such as germs, viruses, fungi and bacteria.

Air Quality Indicator

The digital display on the front of the air purifier indicates the current air quality by measuring the level of fine particulate matter (PM2.5), indoor relative humidity, and indoor temperature.

Fine Particulate Matter

PM2.5
PM2.5 refers to atmospheric particulate matter (PM) that have a diameter of less than 2.5 micrometers, which is about 3% the diameter of a human hair. These particulate matter can come from various sources indoors, from chemicals in cleaning supplies, building products, furniture and carpeting, to mould, bacteria, dust mites and even from cooking. Studies have shown that inhaling too much fine particulate matter can cause health issues and trigger or worsen chronic disease such as asthma, heart attack, bronchitis and other respiratory problems.

Due to the many adverse effects fine particles can inflict on a large number of people, PM2.5 is one of the major pollutants closely monitored by health authorities around the world. The table below provides a rough indication of what levels of PM2.5 are harmful:

Indoor Relative Humidity

Indoor humidity levels also provide a good indication of healthy indoor air quality. In general, a relative humidity level of 45 to 60% is optimum indoors. A humidity level of 50% is recommended to inhibit dust mites, mould, and bacteria growth. In colder climates, a lower humidity level of 30 to 40% may be preferred to prevent condensation on windows and other surfaces.
