The Air Purifier VA- HAP002 is not a common air purifier.
It unifies a purifier, an air quality monitor and a smart device with own software.
The air quality is ranked by the 7 sensors which measure the quantity of PM1, PM2.5, PM10, VOC, CO2, temperature and humidity. These values are given in precise designed pics shown on a 5 inch HD monitor and touch screen. By defining the air purification speed mode you define the allowed quantity of PM and VOC in the air. The software solution creates a history of the indoor air quality values for a period of one year and shows them into a chart. The monitor also gives you feedback about the filter usage, timer, schedule, display settings etc.
The Eco Friendly Multy-layer H13 HEPA Filter contains 0% hard plastic and combines: a pre-filter to capture large particles; H13 HEPA filter to arrests airborne particulate matter, bacteria, dust, pollen, fungi and other; and an interchangeable active carbon mat to absorb smoke, odor and harmful gases.
