Rediair’s 3 stages of
decontamination are:
1.1 - Pre-filter
A washable plastic pre-filter filters coarse dust
particles of more than 5 micrometres, such as
house dust, scales, pollen. The filter can be
washed out with water and reused several
times. GAMA Healthcare recommends
replacing the pre-filter twice a year.
1.2 - Effective formaldehyde filter
A formaldehyde filter with activated
carbon cleans the air of unwanted odours,
gases and substances. It also cleans the
air of harmful formaldehyde in a relatively
quick time. The activated carbon absorbs
the substances, and when the filter is
saturated, the filter must be replaced. GAMA
Healthcare recommends replacement every
six months. In case of strong odour pollution,
a more frequent change is advisable.
1.3 - Highly efficient HEPA filter
(suspended matter filter)
The HEPA 14 filter filters airborne
microorganisms, smoke, and dust particles
down to 1μm in size at a rate of 99.995% or
more. In combination with stage 2, the HEPA-
14 filter can catch microscopic particles
with a minimum diameter of 20 nanometres,
like bacterial mould, dust, allergens, and
airborne viruses. According to the World
Health Organisation, COVID-19 (SARS-CoV-2),
avian flu virus, influenza virus, and legionella
bacteria are larger than 20 nanometres.
