Air Quality Sensor -- Monitor the air quality of the room. This icon lights up Green, Blue or Red to indicate how clean your air currently is.
The included remote control features buttons to control the six main functions, so you can conveniently operate the unit from wherever you are in the room.
Advanced 5-in-1 HEPA Filtration
An air purifier is of course only as good as the filtration system at the heart of it. The AFR-425-SW features an advanced 5-in-1 HEPA Filtration System that uses three separate filters, but features five layers of filtration so most types of impurities are filtered from polluted air.
The first stage uses a pre-filter which traps large particles that may linger in your air like pet hair, fungus and lint.
The second and third stage use a 2-in-1 activated carbon and HEPA filter. The carbon filter has the role of absorbing harmful chemicals often found in common household products, cooking fumes, smoke and other odors which can potentially lead to respiratory problems. The HEPA filter efficiently removes 99.97% of airborne pollutants as tiny as .3 microns. This includes household dust, allergens and pollens.
At the fourth stage, air passes through a Photocatalyst filter. This uses a process known as photocatalytic oxidation which destroys approximately 99 percent of organic contaminants like bacteria, viruses and mold.
In the final stage, there is a UV Wave Bulb. This uses ultraviolet light which is highly effective for breaking down organic molecular bonds. This greatly reduces things such as bacteria, fungi and viruses which often linger in the air.
Despite it’s wide array of filters, Whynter have made this air purifier easy enough to maintain.
The manufacture recommends replacing the 2-in-1 HEPA and carbon filter every 4-6 months to maintain optimal filtering performance. These filters are currently sold on Amazon.
The UV bulb provides 6,000 hours of usage before it needs to be replaced.
There are only two filters which need cleaning periodically.
The Photo catalyst filter should be vacuum cleaned every 6 months using a nozzle or brush attachment on a low power setting to prevent damage to the filter.
The non-reusable pre-filter needs to be washed depending on the air quality in your room. Simply wash it under a tap running lukewarm water for 2-3 minutes then leave it to dry for 12-24 hours before reuse.
