Meet the Winix U450 Signature Series Air Cleaner.

Powerful 5-Stage Air Purification with 12 Month Washable Activated Carbon & HEPA Filters
The Winix U450 includes five stages of air filtration that easily remove over 99% of the dust, allergens, pet dander, hair, dust mites, mold spores, and airborne bacteria often found in homes and rooms—with bacteria killing power in the pre-filters for added protection:
1)    Stage 1—Washable Anti-Bacterial Pre-Filter stops lint, pet hair, dust bunnies, etc., and extends the life of the filter cassette.
2)    Stage 2—Washable Pre-Filter with a CleanCel antimicrobial protective coating kills bacteria and other germs on contact
3)   Stage 3---True, Certified washable HEPA filter that removes over 99.97% of the dangerous sub-micron particles, mold spores, dander, bacteria and more as small as 0.3 microns, and 95% down to 0.1 micron.
4)   Stage 4—The Winix U450 features a premium grade AOC (advanced odor control) activated carbon filter removes 300% more odors (such as pet, cooking, mold, etc) as well as chemicals than standard activated carbon filters—also washable.
5)    Stage 5---the U450 then cleans the air with Winix PlasmaWave technology with healthy negative OH- ions, (no ozone) which instantly kill airborne bacteria, mold spores, viruses. PlasmaWave ions also disintegrate chemical compounds and odors in the air, which further helps to purify the air in your home.
Quiet Operation with 4 Speeds, Automatic Sensors, and a Remote Control
The Winix U450 offers 4 speeds, from whisper quiet for bedrooms and baby rooms, all the way to Turbo mode that will clean the air in a home or room exceptionally fast. The U450’s air pollution sensors monitor air quality and tell the U450 to clean the air whenever pollutants are sensed. There is also a visual meter that gives you a constant reading on your indoor air quality, and you can even watch the meter go from poor to good as the air purifier literally scrubs the air!  Finally, a full function remote control is included (batteries included, too)!

Energy Star Rated for Low Power Consumption
The Winix U450 portable air purifier uses about 40% less energy than non-Energy Star rated air cleaners—and that saves you money on your power bill.
Easy to Use Electronic Controls, Dimmable LED Lights, Too!
The Winix U450 air scrubber also features easy to use electronic controls, and a Filter Change Indicator so you know when the filters need be washed or replaced. For night time or baby room use, the U450 also features LED lights that can be dimmed so they don’t disturb you or your family while sleeping.
