What Is The Hard Indicator Of The Air Purifier?
Feb 20, 2019

Two essential hard indicators for air purifiers:

1. It is necessary to ensure that the indoor air reaches a certain number of air changes (the international is 5 times), that is, the fan built in the air purifier is required to have a certain amount of air. The international standard is to ensure that the air is ventilated five times per hour in the applicable area.

2. The primary purification efficiency of the air purifier must be relatively high, and the higher the purification efficiency (CADR), the better the air purifier.

These two hard-index air purifiers keep indoor pollutants at a lower concentration if there is a continuous source of pollution in the room.
