How to evaluate the parameters of an air purifier?Air purifier

　　A better air purifier must stand the test. In addition to verifying the air purifier with practice, we also look at some parameters of the air purifier to evaluate it. The parameters of the air purifier can be said to be a direct way for consumers to recognize the air purifier Z, so should we start with those parameters of the air purifier?

　　The new national standard is the basis for air purifiers. The "three highs and one low" stipulated by it are what businesses should be loyal and consumers should pay attention to. Therefore, when we are evaluating air purifiers, we must first mention the new national standard The four items basically started.

　　CADR

　　The new national standard definition: CADR refers to the amount of clean air, which refers to the total amount of clean air output per unit time after filtering through the purifier. The unit is m³/h, including particulate matter CADR and formaldehyde CADR.

　　Evaluation method: The volume of clean air produced in one hour, which mainly measures the purification efficiency of the air purifier. For example, the CADR of the particulate matter is 500m³/h, which means that the air purifier is used to purify the particulate matter for one hour, which can purify 500 cubic meters of particulate matter. In the same way, if the CADR of formaldehyde is 200m³/h, it means that the air purifier is used to purify the formaldehyde for one hour, and it can purify the formaldehyde within 200 cubic meters.

　　CCM

　　The new national standard definition: when the CADR value decays to 50%, the total weight of the accumulated purification pollutants (particulate matter or formaldehyde), in mg. Among them, the particulate matter CCM is represented by P, which is divided into four levels, from low to high, respectively P1, P2, P3, P4, and the total weight of the corresponding purified particulate matter is 3000-5000mg, 5000-8000mg, 8000-12000mg, and more than 12000mg. ,Z Advanced is P4. Formaldehyde CCM is denoted by F, and it is also divided into four levels, from low to high respectively F1, F2, F3, F4, and the total weight of the corresponding purified formaldehyde is 300-600mg, 600-1000mg, 1000-1500mg, 1500mg or more, Z advanced is F4.

　　Purification energy efficiency

　　New national standard definition: purification energy efficiency definition: the ratio of CADR clean air volume to rated power, divided into particulate matter purification energy efficiency and formaldehyde purification energy efficiency. When the particulate matter purification energy efficiency value reaches 2, it is a qualified level at this time, and when the ratio reaches 5, it is a high-efficiency level at this time; for formaldehyde purification energy efficiency, when the ratio reaches 0.5, it is a qualified level, and when the ratio reaches 1, it is highly efficient. class.

　　Noise

　　The new national standard definition: when the air purifier reaches the Z CADR value, it corresponds to the amount of sound produced. The new national standard stipulates that when the particulate matter CADR≤150m/h, the machine noise should be ≤55 decibels; when 150450m/h, the machine noise should be ≤70 decibels (the sound of the vacuum cleaner working). Interpretation of the new national standard: The CADR value is getting higher and higher, and the internal fan of the machine must increase the speed, so that the noise will increase accordingly. A truly effective air purifier must not only have a high purification efficiency and ability, but also have a lower noise. good.

　　So how to make use of the new national standard for purchase? In fact, the quality of the air purifier can be judged by the nameplate on the back of the product!

　　In the purchase process, please remember: The new national standard of air purifiers actually points out that the above four items are not that the greater the CADR value, the better, but the greater the CADR value, CCM value, energy efficiency value, and the greater the noise within the specified range. Good boy! It can be called a truly effective air purifier. Most of Yaneng air purifiers meet the new national standard Z high level, welcome to buy and people with lofty ideals to join and cooperate.
