The 4 way
filter system in The Rainfresh Air RFA5000 is exclusive to this
advanced air cleaner and represents the latest in air cleaning
technology.
1) Silver Nano-particle
Pre-filter
Silver nano-particle ions kill microorganisms by
blocking their enzyme system. It is effective in
extremely low doses of 1 ppm. This silver
nano-particle layer prevents the growth of bacteria and other
micro organisms caught in the HEPA filter layer.
2) HEPA Filtration
The HEPA filter traps airborne particles down to
0.3 nm in size.
This captures 99.97% of all particulate matter. Smoke is 0.01 to 1.0
nm in size, Pollen is 0.5 to 3 nm, and Bacteria/germs are 0.03
to 10 nm. The
pleated design provides the maximum filtration surface for
superior performance.
3) Activated Charcoal
Layer
The RFA activated charcoal layer destroys smoke and
odors. While HEPA
filters remove some smoke the activated charcoal greatly
improves performance.
4) Titanium Dioxide
Layer
TiO2 active
radicals break down and decompose VOCs, or Volatile Organic
Compounds, or as we know them, fumes and odors. This layer is
activated by the ultraviolet lamp and eliminates and
microorganisms or VOCs that get by the first 3 stages of the
filter.
