Buy an air purifier to pay attention to these 6 points, and buy it with your eyes closed!
Choose products with formal logos and complete information
When consumers buy indoor large air purifiers
Pay attention to the following
▲ Pay attention to whether the product packaging has a formal logo, including company name, product name, product model, implementation standard, after-sales hotline, and certification mark;
▲ Pay attention to the air purifier CADR (purification efficiency) and CCM (cumulative purification) indicators, such as CADR (particulate matter), CADR (formaldehyde), CCM (particulate matter), CCM (formaldehyde), and energy consumption, noise (maximum air volume) , applicable areas and other important indicators, and pay attention to whether the above indicators are fully marked;
▲ Also, pay attention to the product manual or its body, whether it is marked with the start-up operation guide, use safety tips and filter replacement operation instructions, etc., to avoid the impact of the cheap and best air purifier due to incomplete information.
Choose products that meet the actual needs of the home
When consumers purchase air purifiers, they should pay attention to and consider the “CADR (purification efficiency)” index. Just as buying air conditioners should choose the number of horses according to the size of the space, different space areas should match the air purifiers with different CADR values. For example, a 30 square meter room and a “CADR” 450 air purifier will have a better purification experience.
In addition, for particulate matter, formaldehyde (gaseous pollutants), allergens and other different pollutants, it is best to purchase products with corresponding purification functions.
Choose products with high quality and good price
At present, there are many brands of air purifiers on the market, and the price difference is large. Consumers should not argue about quality.
Low-cost products such as “100 yuan machines” have low cost, often with poor quality and high noise. They not only fail to achieve the desired purification effect, but also bring noise pollution to the home, and the high price is not completely equal to high quality, some high-priced products, In fact, it contains a lot of marketing costs. Some of the features in the product belong to the business exaggeration of publicity, play with the concept, and some of the functional indicators are directly marked by the merchants to maximize the eyelashes.
At the same time, consumers should not blindly pursue foreign brands and high-end brands, because each country has different national conditions. For example, some countries in foreign countries have milder levels of formaldehyde and smog. The corresponding brands of air purifiers mainly filter pollen and large. Particulate matter is not entirely suitable for the needs of Chinese consumers.
Choose pre-sale and after-sales guaranteed products
Whether buying products online or offline, consumers should purchase through formal channels. Do not blindly believe in channels such as mergers, sales, membership, etc., and avoid buying counterfeit and shoddy products.
At the same time, as a high-consumption product, an air purifier is particularly important for after-sales service. Some air purifiers sold through third-party platforms or dealers have a short warranty period, and subsequent maintenance services have defects, which greatly shorten the product life cycle, so consumers When purchasing an air purifier, you should carefully understand the after-sales service, warranty terms, and restrictions of the product to avoid unnecessary troubles in the after-sales process. In addition, after the consumer purchases the product, he must keep the invoice and other shopping vouchers for future use.
Choose a product certified by a third-party certification body
When consumers purchase an air purifier, they can pay attention to whether the product has a “star certification” from a third-party certification body.
“Star certification” is based on the requirements of the industry group standard “Filtering Air Purifier Particle Control Performance Grading”, and the removal of energy efficiency, cumulative purification, and noise of “particles, formaldehyde, microorganisms, allergens” and other pollutants. The grading evaluation of the indicators is “9 stars”. “Star certification” puts higher requirements on the quality of air purifiers. Consumers can directly judge the quality of air purifiers by means of “number of stars”.
Master the correct use of the product
At present, the air purifiers currently on the market mainly use filter type. The filter element can not be used repeatedly by cleaning, and the service life is generally about six months. Once the filter adsorption area reaches saturation, the machine work efficiency will decrease. There is even a risk of secondary pollution, so consumers should replace the filter element in time according to the degree of indoor pollution and product use cycle.
In addition, there are currently air purifiers purified by the principles of high-voltage static electricity, negative oxygen ions, water washing, etc., in which high-voltage static electricity and negative oxygen ion air purifiers are usually promoted without replacing the filter screen, but the consumption of such products is purchased. Particular attention should be paid to the risk of elevated ozone concentrations. The use of the principle of water washing in air purifiers should be concerned with the risk of harmful microbial growth.
