Airthereal: AEH300 Air Purifier & Humidifier Combo Review + Giveaway

We’re in Minnesota and I’ve already started noticing the shift that comes with the arrival of fall—cooler temperatures, drier air, and the telltale signs of it in my throat and skin. So when Airthereal reached out and asked if I’d try their AEH300 Air Purifier & Humidifier Combo, the timing couldn’t have been more perfect.  This 2-in-1 Air Purifier and Humidifier is a powerful, dual-purpose solution that helps keep our home’s air clean and comfortably balanced.

Features You’ll Love:

• Works For Large Spaces:  The AEH300 efficiently purifies the air in rooms up to 1325 ft².
• Advanced 3-Stage Filtration System:  It captures 99.97% of airborne particles as small as 0.03 microns—including smoke, odors, pollen, and allergens – delivering fresher, healthier air.
• Intelligent Air Quality Management:  Equipped with real-time PM2.5 detection and a color-coded air quality indicator (green, orange, red), this device automatically adjusts its fan speed to maintain optimal indoor air quality—so you can breathe easy without giving it a second thought.
• 2-in-1 Performance:  This unit functions as both a humidifier and air purifier in one.
• Detachable Design:  The humidifier module can be detached for standalone air purification. Featuring a 1.5L water tank and smart sensors that monitor real-time temperature and humidity, it works to maintain a balanced and comfortable indoor environment.
• Top Mounted Filtration:  This machine filters water before releasing moisture into the air, helping prevent the spread of minerals, white dust, and pollutants—unlike traditional ultrasonic models. And since it produces no visible mist, it’s safer for furniture, electronics, and overall indoor air quality.
• Timer:  Choose from (1–24 hrs) and child lock it for safety and convenience.
• Replaceable Filters:  The HEPA filter only needs to be replaced every 6–8 months while the Humidifier filter should be replaced every 6 months.
• Customize Your Comfort:  Choose from four versatile fan speeds to suit your daytime needs, then switch to the ultra-quiet 24dB sleep mode at night for uninterrupted rest and a truly peaceful sleep environment.

Accessing the filters on the AEH300 is incredibly easy—one of the only setup steps was simply removing the plastic bags from the pre-installed filters.
