The Airthereal AEH300 uses a 3-stage filtration system — nylon mesh pre-filter, HEPA filter (98% rated efficiency), and activated carbon — to capture PM2.5, dust, pollen, and odors, while a 1.5L water tank adds up to 300 ml\/h of moisture via filter-based evaporative humidification. A real-time PM2.5 color display and automatic fan speed adjustment make it suited for living rooms, bedrooms, and offices up to the unit’s rated coverage area.\u003c\/p\u003e\u003ch2\u003eWhy This HEPA Air Purifier and Humidifier\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eBuilt for two functions in one unit\u003c\/strong\u003e — purification (CADR 300 m³\/h) and evaporative humidification (up to 300 ml\/h) operate together or independently, reducing the need for two separate appliances.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBuilt for evaporative humidification, not ultrasonic\u003c\/strong\u003e — filter-based evaporation does not release visible mist, minerals, or white dust into the air, and self-regulates to avoid over-humidification.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBuilt for real-time air quality feedback\u003c\/strong\u003e — the color-coded PM2.5 display (green: excellent, orange: good, red: poor) shows current air quality and triggers automatic fan speed adjustment.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBuilt for scheduled operation\u003c\/strong\u003e — a 1–24 hour adjustable timer allows automatic start and shutdown without manual intervention.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eBuilt for family spaces\u003c\/strong\u003e — a child lock prevents accidental setting changes;

It uses a 3-stage filtration system: nylon mesh pre-filter, HEPA filter rated at 98% efficiency, and activated carbon for odor capture.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow does evaporative humidification differ from ultrasonic humidification?\u003c\/strong\u003e\u003cbr\u003eThe Airthereal AEH300 uses filter-based evaporative humidification, which passes air through a water-saturated filter rather than producing a visible mist. This means it does not release minerals or white dust into the air, self-regulates to prevent over-humidification, and produces no visible vapor — making it less likely to leave residue on nearby surfaces or electronics.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow large is the water tank and how often does it need refilling?\u003c\/strong\u003e\u003cbr\u003eThe AEH300 water tank holds 1.5L (3.2 pints). At maximum humidifying output of 300 ml\/h, a full tank lasts approximately 5 hours at maximum output — longer at lower settings. A transparent tank window makes the water level visible without removing the tank.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the purifier and humidifier functions be used independently?\u003c\/strong\u003e\u003cbr\u003eYes. The Airthereal AEH300 can operate in purification-only mode or combined purification and humidification mode. Refer to the user manual for mode selection instructions.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhen does the filter need to be replaced?\u003c\/strong\u003e\u003cbr\u003eThe AEH300 displays an F0 indicator and activates a red alert light when the filter is due for replacement. Filter life varies based on usage and air quality conditions — see the user manual for replacement intervals and compatible replacement filter part numbers.\u003c\/p\u003e\u003chr\u003e\u003cp\u003e\u003cem\u003eThe information presented on this page is for general wellness and educational purposes only.
