In December, most of the central and eastern parts of China experienced persistent smog weather again. How to fight against PM2.5? The preferred choice for many consumers today is to buy an air purifier. Here, the staff of Shandong Rongcheng Inspection and Quarantine Bureau purchases air purifiers for you:
It is necessary to ensure that the indoor air reaches a certain number of air changes. The international standard is to change the air for 5 times per hour in the applicable area.
The purification efficiency must be relatively high, and the higher the purification efficiency (CADR), the better the air purification effect.
If the room is large, you should select an air purifier that purifies the air volume per unit time. In general, larger purifiers have a higher purification capacity. For example, a room of 30 square meters should have an air purifier of 120 cubic meters per hour.
Purified filter cartridges (including highly efficient catalytically active carbon) with regenerative capacity are selected to extend the service life; some static products do not need to be replaced with relevant modules and only need to be cleaned regularly.
The air purifier has a 360-degree circular design for the air inlet and outlet, and also has a one-way air inlet and outlet. Since the room layout will affect the purification effect, if you want to achieve randomness in the product placement, you should choose a product with a circular inlet and outlet design.
