In the past two decades, we can intuitively feel that air pollution has become more and more serious, especially in the autumn and winter seasons in the north, smog attacks, which seriously affects people’s daily travel. It is not difficult to find that more and more adults, young people and even children are suffering from different degrees of respiratory diseases, such as rhinitis, bronchitis, asthma and so on.
- Why do you need correct air purifier filter replacement ?
Regarding the air pollution of the large environment, our personal ability is limited, but for our own family, it is particularly important to create a healthy living environment. Nowadays, many people like to design and decorate houses with their own characteristics, and do not want to use the same hardcover houses. If you want to diversify the style and design, it is inevitable to beat and beat. The demolition and rebuilding of walls, the painting of paint, and the moving in of furniture have all brought invisible crises to our living environment – formaldehyde, benzene, TVOC and other decoration pollutants. Coupled with the haze and dust in the environment, the indoor air quality is not optimistic. For improving indoor air quality, it is the professional category of air purifier filters.
2. Numerical reference meaning
1. CADR value
The CADR value is the clean air output ratio, which is divided into two contents: the solid CADR value, that is, the CADR value of particulate matter, which can be understood as: how many cubic meters of particulate matter in the air can be purified in 1 hour. The gaseous CADR value, that is, the formaldehyde CADR value, can be understood as: how many cubic meters of formaldehyde in the air can be purified in 1 hour.
From this, we can know that the larger the clean air output ratio, the higher the purification efficiency of the purifier. Undoubtedly the most important point of an air purifier.
2. CCM value
The CM value is the total mass of the target pollutants accumulated in the purification treatment when the clean air volume of the air purifier decays to 50% of the initial value. We can simply understand it as the continuous purification ability of the air purifier. For consumers, this indicator means that this indicator can be used to compare the service life of the air purifier filter.
The particle CCM is represented by P, which is divided into four grades, from low to high, P1, P2, P3, and P4, and the highest grade is P4. Formaldehyde CCM is represented by F, which is also divided into four grades, from low to high, F1, F2, F3, F4, and the highest grade is F4.
Only a high CADR does not mean that the air purifier is effective. It also depends on whether the CCM value is also high, so as to prove that this air purifier not only has fast purification efficiency, but also has strong purification ability, and the service life of the filter is longer. Long
