Filters And Performance
Winix AM90 room air purifier uses a familiar 4-stage advanced PlasmaWave Technology to filter the air. Starting with the first line of defense, you have a fine mesh pre-filter that traps large particles in the air mainly dust, hair, fiber, and lint. The pre-filter is washable so you can clean it whenever it is clogged with dust. Next, the activated carbon filter will absorb smoke and odors coming from cooking, pets, diaper, food, cigarette, cleaning products. It can also remove harmful chemicals such as VOCs, radon, asbestos, formaldehyde while prolonging the HEPA filter lifespan. For non-smoke particles, the True HEPA filter capture 99.999% of allergens in the air as small as 0.003 microns including mold, pollen, pet dander, and germs. Finally, PlasmaWave Technology discharges Hydroxyls to neutralize bacteria and viruses including influenza strain H3N2. The dual polarity ions (positive/ negative) naturally and safely remove hydrogen from the molecular structure of air pollutants without creating ozone byproducts.Noise And Energy Usage
Winix AM90 air purifier will run silently if you choose to. In sleep mode, the noise level is at a whispering 27 dB (lower than low speed) that you can sleep right next to it without any noise distraction. As an Energy Star certified unit, power consumption is very good that you can run it 24x7 without adding much burden to your utility bill. Running in a standard 12 hours operation, the electric cost is estimated at about $0.05 per day, $1.6 a month, or 19 dollars a year.
