The Philips AC3737/10 air purifier combines air purification and humidification, with a clean air delivery rate (CADR) of 505 m³/h. It uses a NanoProtect HEPA filter, activated carbon filter and pre-filter to remove particles as small as 0.003 μm, as well as formaldehyde, NH3, H2S and VOCs. The AeraSense sensor monitors the air 1,000 times per second and displays allergens, PM2.5 and humidity levels in real time.

Humidification is based on NanoCloud technology and features four settings and automatic adjustment, while the Philips Air+ app supports remote control and scheduling. Features include automatic mode, humidity and temperature sensors, a display, Wi-Fi and multiple fan speeds.
