The Winix C545 is a 4-stage True HEPA air purifier with WiFi connectivity and PlasmaWave technology, designed to effectively clean rooms up to 360 square feet. AHAM verified with CADR ratings of 243 CFM for dust, 232 CFM for smoke, and 246 CFM for pollen, it provides 4 air changes per hour to thoroughly purify your indoor air every 15 minutes.

The advanced filtration system includes a washable fine mesh pre-filter that captures large airborne particles, an activated carbon filter that reduces VOCs and household odors from cooking, pets, and smoke, and a True HEPA filter that captures up to 99.99% of airborne allergens including pollen, dust, smoke, pet dander, and other ultrafine particles as small as 0.003 microns. The proprietary PlasmaWave technology releases both negative and positive ions to form hydroxyls that attack airborne pollutants such as viruses, bacteria, germs, odors, and chemical gases.

Smart features include WiFi connectivity for control and monitoring through the Winix Smart App, compatibility with Alexa for voice control, dual smart sensors with auto mode that automatically adjusts fan speed based on real-time air quality measurements, and an LED air quality indicator that changes color based on current conditions. The unit automatically activates its ultra-quiet sleep mode when the room is darkened and returns to auto mode in the presence of light. Operating at just 28 decibels on the lowest speed, it is quieter than a whisper and suitable for bedrooms and nurseries.
