Elevate your home's air quality with the PhiloDeco Smart WiFi Air Purifier!Designed for bedrooms, living rooms, and offices, this advanced unit features an H13 True HEPA filter that captures 99.97% of airborne particles as small as 0.3 microns—effectively removing pollen, pet dander, dust, smoke, and odors to create a healthy breathing environment for allergy and asthma sufferers. With a CADR of 110 CFM (approx. 187 m³/h), it easily purifies medium-to-large rooms, refreshing the air about 4–5 times per hour. A built-in PM2.5 sensor provides real-time air quality feedback via a three-color LED indicator (green/orange/red), while the Tuya Smart app enables remote control—allowing you to adjust fan speeds (levels 1/2/3, Auto, and Sleep modes), set timers, activate the child lock, and receive filter replacement alerts from anywhere. In Sleep mode, operation is as quiet as a whisper (30dB), ensuring undisturbed rest. Its compact design, combined with child lock and timer functions, offers both safety and peace of mind.
