Air purifier filter standards will soon be introduced or "Unified rivers and lakes"

OFweek smart home network news: "If the filter has not changed for one year, is it useless, and even will become a secondary source of pollution?" "But if you change the filter, eight hundred or even one thousand dollars will be spent This is just an air purifier screen filter money. In a home, you must not use two or three units, change a three or two filters?"

This paradox, it is estimated that most people who have used an air purifier have experienced it. The cost of filter materials in the later stages of air purifiers has often become the focus of consumer anger. Some imported air purifiers do have a relatively high filter price, which is not a small family expenditure. What is even more worrying is that some shoddy filters are not cheap, and they are actually bullying consumers.

Recently, the reporter learned that the National Standardization Technical Committee of Household Electrical Appliances is promoting the development of standards for air purifier filters. The two industry standards of “Air Filters for Air Purifiers” and “Static Filters for Air Purifiers” have come to an end. It is expected to be introduced in 2018. The introduction of the standard will provide the basis for consumers to purchase suitable filters, and will also provide guidance for the industry's unified declaration.

Standards are not unified to form a chaos

Most of the filter media comply with foreign standards. The standards are not uniform and cannot be compared at the same time, causing inconvenience to both manufacturers and consumers.

After the implementation of the new national standard for air purifiers, as the core component of the purification product, the filter screen is also affected by the new national standard, and it has been standardized to a certain extent. However, there are still some factors that hinder the development of the industry.

"The filter material market is not chaotic, mainly because most of the filter media comply with foreign standards. The standards are not uniform and cannot be compared at the same time, causing inconvenience to both manufacturers and consumers." Dr. Zhang Zhiqiang, manager of Philips Life Household Appliances, told "China Electronics News" reporter.

Analysis of the reasons for this phenomenon is actually not complicated: one is the lack of Chinese standards for filter media, and the other is the high sales volume of foreign brands of air purifiers, each occupying a “mountain head”, thus forming a situation that pursues their respective standards. At present, the foreign market share of air purifiers in the domestic market accounts for more than 70%, including American brands, German brands, Japanese brands, Swedish brands, and so on. These brands have their own set of standards and rhetoric in promoting the performance of the filter, so that consumers can not be compared horizontally, there is always some confusion in the purchase.

This feeling of incomparable comparison does give some companies an opportunity. "Some imported air purifier products, the filter also does exist excessively high-priced, low-cost profits." Senior life home appliances evaluation Li Yang told reporters, "But most of the filter's profit margin in the mainstream home appliances profit The level of the rate, especially the products of well-known domestic brands, has a relatively high price/performance ratio for filter materials, and there is basically no huge profits. Certainly it does not exclude some phenomena that do not pay attention to quality and fisheyes."

Filter labels help to unify claims

The industry standards for these two air-cleaning filters are mainly to provide guidance for enterprises and consumers to purchase filters.

“The industry standard for these two filters is mainly to provide guidance for enterprises and consumers to purchase filters. At present, when consumers purchase filters, they first consider the original supplier of filters, followed by professional filter factory. The production of filter mesh, but many even if the original production of the filter, there will be performance instability, so we introduced a standard specification, hoping to improve the quality of the filter." Standard lead unit, China Household Electrical Appliances Research Institute Zhang Xiao, director of the Indoor Environmental Analysis and Testing Center, told the China Electronics News reporter.

Regarding the content of the standard, Zhang Xiao revealed that the two industry standards are distinguished according to the principle of purification. The performance and technical indicators are mainly the single filtration efficiency and the dirt-holding capacity. The former indicates the purification capacity and the latter indicates the service life of the filter. The standard is mainly aimed at filters for household-type purification products and does not involve industrial products. However, as the standard has not yet been finalized, the specific content may be fine-tuned.

“The new national standard of air purifier GB/T 18801 is the product standard. The product standard was first made, and the effect was obvious in the implementation for one year, and the industry is very much recognized. Now the starting point for the component standards is to refine the standard system. Currently on the market The standards followed by the filter are European Standard, American Standard, and Japanese Standard, which cannot be directly compared by consumers, and the formulation of standards can unify the declaration of filters and facilitate the purchase. In addition, the filter standard will also provide filter manufacturers with test basis. When supplying air purifier manufacturers, there is a unified standard grade division,” said Zhang Zhiqiang.

Upstream and downstream will change

If the two targets are implemented, those filters that comply with foreign standards may all be unified into Chinese standards.

If two filter media industry standards are implemented, they will have a certain impact on the industry upstream and downstream industry chains.

First, for air purifiers that use electrostatic dust-collection filters, the standard's role will be greater. Industry sources pointed out that the electrostatic dust collection method involves discharge, so it will bring about the problem of ozone release. The introduction of this standard will standardize the products of some companies and make products more secure. Zhang Xiao told reporters that in the domestic market, the market share of electrostatic precipitator air purifiers is about 30%, and the rest is basically a filter air purifier.

Second, the filters that follow foreign standards may all be unified to Chinese standards. It should be noted that these two filter material standards are in fact non-compulsory industry standards that companies can follow or choose not to follow. If these two standards are recognized by the market, that is, if most consumers accept the use of these two standards as the main reference for the purchase of filter media, most companies will have to follow the laws of the market and abandon the foreign standards so as to comply with the Chinese standards. .

"These two industry standards will not have an essential impact on Sharp, because Sharp's products have requirements for filtration efficiency and dirt content. Sharp will also focus on changes in the standard content to ensure that the Sharp brand of air purifier meets the government's requirements. Requirements." Sharp (China) Health and Environment Commodity Unification Feng Jiejian told the "China Electronics News" reporter.

Local companies are actively participating in the formulation of domestic standards. TCL small household electrical appliance responsible person revealed to reporters, TCL is involved in the preparation of these two industry standards, TCL will also actively promote the popularization of these two standards. The person in charge of research and development told reporters that TCL's air purifiers are all filter-type filters, and they all meet the requirements of the standard.

Third, professional filter manufacturers may show up. As the upstream chain of the air purification industry, professional filter manufacturers usually do not face consumers directly because the original filter is more easily accepted by consumers. If the filter has a unified standard, then as long as the filter meets national standards, consumers are likely to buy.
