1.Insulation made of EPP foam with light weight and high noise reduction ability that can withstand water and moist. EPP foam is 100% recyclable and non-toxic that will lessen the environment impact. heat resistance (-40-130 degree).

2.The purification efficiency is up to 99% and using hexagon heat exchanger core, the  efficiency can reach up to 82 %.            

3.When the temperature difference between the inside and outside is almost equal, the intelligent automatic air valve open to bypass the air and reduce the motor resistance for energy saving.            

4.Foam forming, unique vortex design, reduce noise effectively. Dual motor that can operate independently according to real time parameters.           

5. IPS intelligent control system with user friendly interface, Measure and indicate PM2.5 value in real time and connected to Enchoy cloud and are easily controlled by remote or APP.
