With the worsening of the environment, air purifiers have gradually entered the home, and become the essential products after refrigerators, televisions and air conditioners. Unlike other home appliance industry, as a new industry, the air purification industry is relatively chaotic due to the lack of a comprehensive system of industry norms. There are varieties of chaos: shoddy, exaggerated functions, price gouging. All sorts of chaos falls, rights and interests suffers the most serious should belong to consumer.
In order to protect the legitimate rights and interests of consumers and further regulate the market, the first mandatory standards for air purification industry came into effect in 2016. In order to facilitate memorization, some people specially extract its essence, namely the so-called “three high and one low”. Olansi healthcare will explain you what are they.

As the first mandatory standard in the purification industry, it puts forward four core performance indicators: CADR (clean air output), CCM (cumulative purification amount), purification efficiency and noise. The so-called three high and one low are high CADR, high CCM, high purification efficiency and low noise.
CADR (clean air volume), expressed in cubic meters of air that can be purified per unit of time, directly reflects the actual performance of the purifier. The higher CADR air purifier has, the stronger the purification capacity. However, higher CADR value does not mean better. The selection of CADR value should be reasonable according to the indoor living area, so as to avoid the unsatisfactory purification effect caused by small machine big room or the power waste caused by bigger machine small room. Big CADR machine used in small room besides cause the excessive consumption of electric quantity, the purifier that can send out ion still can release ion too much and affect family health.
How to choose a suitable CADR according to the size of the room? Here is a decision: (0.07~0.12)*CADR= usable area.
Special attention should be paid to the fact that CADR of particulate matter is different from that of harmful gases, and CADR of particulate matter is higher than that of harmful gases.
CCM (cumulative amount of purification) is a parameter reflecting the service life of filter screen of the purifier. The larger the value is, the longer the service life of filter screen is, and the lower the replacement frequency is. It is a cost performance index of the product. If CADR is a measure of how fast you can go, CCM is a measure of how far you can go, so CCM is an important indicator that can’t be ignored.
Purification efficiency, the amount of clean air per unit power consumption of an air purifier (CADR to rated power), is a measure of power consumption. In general, a higher value indicates that the purifier has both energy saving and purification effect. Need special attention here is that the particles of purification efficiency level division and the purification efficiency of formaldehyde level division standard is different, so cannot treat as the same, the specific energy efficiency level is defined as: particulate matter numerical grade 2 for qualified, the purification efficiency of 5 for the high level, and the purification efficiency such as formaldehyde, 0.5 for qualified level 1 is the efficient level.
Noise, the indicator that affects the purifier product experience, noise is definitely the lower the better. How to determine the performance index of the purifier mainly depends on the value in two states, one is in the working mode and the other is in the sleep mode. Among them, the noise in working mode with less than 50 decibels is better, sleep mode with less than 30 decibels of the product is better.
