1. The front air purification device adopts the series absorption method to purify the humidity, formaldehyde and other volatile substances in the air.2. The absorption tube is filled with an appropriate amount of granular activated carbon and color-changing silica gel. The activated carbon filling amount is 0.5kg for at least 2 months, the color-changing silicone filling amount is 1.0-1.5kg, and the relative humidity of the ambient air is 65%-82%. It can be used continuously for 4d~8d.
3. When measuring the purification effect, take formaldehyde as the detection object, set points in the air inlet of the front air purification device and the environmental test chamber of the purified purifier, and perform intermittent measurement to measure the air inlet of the front air purification device. The formaldehyde concentration is 0.01~0.1mg/m3, and the formaldehyde concentration in the test chamber after purification is less than 0..01mg/m3, which is outside the detection limit of phenol reagent spectrophotometry.
