Features and Benefits
How The 8-in-1 Removes An Amazing 99.99% Of Impurities!
#1 | Pre-Filtration
To stop large particles clogging your precision filters we start with an Aluminium Alloy Filter to capture dust, dander, pollen and toxins larger than 5 microns.
#2 | Neutralize Chemical Gas
The Cold Catalyst Filter removes bacteria, and toxic environmental gasses, from things like car exhausts, cleaning chemicals, new furniture, carpets, wallpaper and bedding. These chemicals include: formaldehyde, ammonia, benzene, xylene, toluene, TVOC, hydrogen sulfide and more. All that’s left over is safe carbon dioxide, and water!
#3 | Odor Removal, and Gas Absorption
While step #2 chemically catalyses toxic gasses, the Activated Carbon Honeycomb absorbs anything left over. This second line of defense, with it’s 98% absorption rate guarantees the 99.99% removal of all harmful gas. It’s also the first step in our Smart Odor Elimination.
#4 | Large Microbe Removal
To prevent large bacteria and microbes clogging your precision HEPA filter, we send them through the AntiMicrobial Cotton Filter. This traps and neutralizes 99% of microbes like airbone germs, micro-organisms and bacteria larger than 5 microns.
#5 | Fine Particle Removal With True HEPA
The HEPA Filter removes 99.97% of particles that are only 0.3 microns! That includes smoke, germs, allergens, bacteria, viruses, dust, and mold spores. You’ll be pleased to know, the World Health Organization, declared the Avian flu virus, influenza virus, and Legionella bacteria to be greater than 0.2 microns, obviously within the HEPA’s range. That’s why you see this filter around medical facilities, aircrafts, airports, offices and malls.
#6 | Sterilization
You choose if you want to activate the germicidal UV Sterilization Lamp. It kills bacteria, and viruses, and eliminates musty and bad odors leaving air fresh and pure. It’s the second step in our Smart Odor Elimination! Great for those with compromised immunity, after a nasty household accident, to sterilize kitchen surfaces, or remove stubborn odors .
#7 | Purification
Similar to the UV, you choose if you wish to activate the Negative Ion Generator. This electrical filter charges the air with anions and removes ultra-fine 0.01 micron particles. It is Ozone Free, and for those who know about the hazards of ozone, you’ll naturally be pleased.
#8 | Humidifying
Fill the water container and the Humidifier will start automatically. Obviously, if you suffer with skin, chest, throat, and nose complaints due to dry air, the Humidifier is welcome relief.
