Winix C545 Air Purifier

The Winix C545 is AHAM Verified for rooms up to 360 square feet. It is best suited for bedrooms, living rooms, or home offices of that size to ensure optimal air circulation and filtration.

The system uses a washable pre-filter to catch large dust and pet hair, an activated carbon filter to reduce odors, a True HEPA filter to capture 99.97% of tiny airborne particles, and PlasmaWave technology to break down pollutants at a molecular level.

The auto-mode is highly effective because it relies on built-in smart sensors that constantly monitor your indoor air quality. When the sensors detect an increase in pollutants, the unit automatically adjusts the fan speed to clean the air more aggressively, then slows down once the air is clean.

Yes, it features a dedicated Sleep Mode that lowers the fan speed and dims the lights on the control panel. This allows the unit to operate at a very low decibel level, ensuring it won't disturb you while you rest.

No, the app is optional. While the Wi-Fi connectivity and smartphone app offer convenient remote control and real-time air quality monitoring, you can operate all the essential functions, including fan speed and mode settings, directly from the unit's control panel.

Filter life depends on your environment and usage, but generally, the True HEPA and carbon filters should be replaced every 12 months. The pre-filter is washable and should be cleaned every few weeks to keep the system running efficiently.
