With the arrival of the summer decoration peak, the air purifier will usher in a round of hot sale. The new national standard for air purifiers was implemented on March 1 this year, and four indicators affecting its purification effect were identified: clean air volume, cumulative purification amount, energy efficiency rating and noise standard, and its core parameters and working principles were required. Clearly marked. Industry insiders reminded that the new national standard not only plays an important role in regulating the market, but also an important reference for consumers to purchase.
Choose a purifier to see two major indicators first
In the city's many electrical stores, consumers who purchase air purifiers are not rare. Mr. Wang, who lives in the city center, said that the living room window is close to the main road, and dust and automobile exhaust pollution are inevitable. Buying an air purifier is more assured. There are still many buyers because the home has just been renovated. "How much decoration will bring some pollution to the indoor air, it is necessary to purify it."
According to industry insiders, the mixed air purifier market has made many consumers feel at a loss. This situation has changed with the introduction of the new national standard. Experts involved in the revision of the new national standard, the first choice of air purifiers should look at two core standards: clean air volume (CADR value) and cumulative purification (CCM value), respectively, to measure the purification capacity of an air purifier and The sustainability of purification capabilities. Simply put, the larger the CADR value, the faster the purification efficiency of this machine, the larger the applicable area; the larger the CMM value, the greater the endurance of the machine and the longer the use time.
Consumable filters are also included in the cost
Experts remind that the purchase of air purifiers for non-disposable consumption, the filter that plays a key role is the consumables that need to be replaced regularly, and should also be included in the cost. The merchants often do not express the cost of the filter, and consumers should ask when they purchase.
At present, the mainstream air purification equipment is divided into a filter type and an electrostatic adsorption type, and the price is relatively close to the filter type air purifier, generally using a HEPA filter, an activated carbon filter, etc., which can filter fine particles and adsorb formaldehyde, benzene, ammonia and the like. gas.
Experts suggest that consumers should pay attention to the particle size of the HEPA filter when purchasing air purifiers. The current national standard is 0.3 microns. The threshold for filter products is low, and consumers are encouraged to purchase products that have been certified by an authoritative testing organization.
