Stainless Steel Water Filter

In recent years, the water filter market has shown explosive growth. According to data from Aowei Cloud Network, the retail volume of water filters in my country climbed to 20 million units in 2024, an increase of 15% over the previous year. At the household level, the penetration rate of water filters has exceeded 40%, which means that at least four out of every ten households are equipped with water filters; in terms of commercial places, the equipment rate has also reached 30%, and office buildings, restaurants, hotels, etc. have introduced water filtration equipment to ensure the safety of daily water use. ​


Cleaning and maintenance are extremely critical to maintaining the performance and extending the service life of Stainless Steel Water Filter. Taking the reverse osmosis water filter as an example, if the correct maintenance process is followed, its core component, the reverse osmosis membrane, can serve stably for 3 to 5 years and continue to supply users with high-quality direct drinking water. However, if maintenance is neglected, the reverse osmosis membrane will lose its effectiveness in just 1 to 2 years due to a large amount of impurities blocking and bacterial growth. At this time, the filtering effect of the water filter is greatly reduced. After testing, the impurity content in the effluent can soar several times, and the number of bacteria is far beyond the national standard, which seriously threatens the health of users. Not only that, a water filter that is not properly maintained will consume 20% to 30% more energy than a properly maintained device, which invisibly increases the user's cost of use.

 

2. Analysis of key points of cleaning and maintenance of various water filters

 

Activated carbon water filter


Activated carbon water filter mainly relies on the adsorption characteristics of activated carbon to remove odor, residual chlorine and some organic matter in water. However, as the use time goes by, the adsorption capacity of activated carbon will gradually become saturated. Under normal circumstances, the adsorption capacity of ordinary activated carbon filter will decrease by about 50% after 4 to 6 months of use. It should be noted that the activated carbon filter cannot be simply cleaned by water washing, because water washing not only cannot completely remove the impurities adsorbed inside it, but may also cause a large amount of activated carbon particles to be lost, thereby affecting the normal operation of the water filter. Based on this, it is recommended to replace the activated carbon filter in time every 4 to 6 months to ensure the adsorption effect of the water filter.


Ultrafiltration water filter


Ultrafiltration Self Cleaning Filter Industrial uses ultrafiltration membrane to filter bacteria, colloids and macromolecular organic matter in water. In areas with poor water quality, ultrafiltration membranes are prone to clogging. Usually, after 3 to 4 weeks of use, the ultrafiltration membrane may be significantly clogged, and the water flux will drop by 30% to 40%. Moreover, the ultrafiltration membrane is extremely sensitive to the cleaning method and cannot withstand high temperatures or strong chemical agents. In daily maintenance, a simple backwash operation every 3 to 4 weeks can effectively remove impurities on the surface of the ultrafiltration membrane and maintain its water flux; the replacement cycle of the filter element is relatively long, and it is generally replaced every 2 to 3 years. ​


Ceramic water filter​


Ceramic water filters are favored by some users due to their natural environmental protection and high filtration accuracy. However, the surface of the ceramic filter element is prone to various impurities and needs to be cleaned regularly. However, the ceramic filter element is relatively fragile. If the operation is not careful during the cleaning process, such as using a hard brush or excessive force, it may cause the filter element to break, thereby causing the water filter to lose its filtering function. Therefore, it is usually recommended to use a soft brush to gently brush the surface of the filter element every 2 to 3 weeks to ensure the normal use of the filter element.

 

3. Incorrect cleaning and maintenance behaviors and serious consequences

 

Water quality deterioration​


Ms. Wang in Shanghai installed an activated carbon Self Cleaning Water Filtration System at home, but for 3 years, she did not replace the filter element or perform any cleaning operations. According to a professional testing agency, the bacterial content in the water flowing out of the water filter exceeded the national standard by 10 times. Long-term drinking of such water caused Ms. Wang's family to frequently experience symptoms such as gastrointestinal discomfort, which seriously affected the health of the family. ​


Equipment damage​


A Beijing office building installed multiple ultrafiltration water filters at one time to provide drinking water for office staff. However, during the subsequent use, the staff only wiped the surface of the water filter and completely ignored the backwashing and replacement of the ultrafiltration membrane filter element. After only 8 months of use, multiple water filters experienced a sharp drop in water flux. Upon inspection, the ultrafiltration membrane was severely blocked and damaged. In the end, it cost tens of thousands of yuan to replace the filter element, which brought unnecessary economic losses to the company.

 

4. The current status of lack of industry standards and improvement paths

 

At present, the water filter cleaning and maintenance industry lacks unified and clear standards. The cleaning and maintenance requirements and methods of water filters of different brands are very different, which makes consumers feel at a loss in actual operation. At the same time, there is a serious shortage of professional water filter cleaning and maintenance service agencies in the market. Many non-professionals cannot achieve the expected cleaning and maintenance effects due to irregular operations and lack of professional knowledge when performing cleaning and maintenance operations. On the contrary, it is very easy to damage the water filter. ​


To improve this situation, industry associations and relevant regulatory departments should play a leading role and organize experts to formulate unified cleaning and maintenance specifications as soon as possible. In the specifications, it is necessary to clarify the cleaning and maintenance cycles, specific operation methods and related technical requirements of different types of water filters. In addition, it is necessary to strengthen the training and management of cleaning and maintenance service agencies and practitioners, establish a strict qualification certification system, and improve service quality and professional level from the source. At the same time, through various channels, strengthen publicity and education for consumers, improve consumers' awareness of the importance of cleaning and maintenance of water filters, and guide consumers to use and maintain water filters correctly.

 

5. Strategies and future prospects for improving cleaning and maintenance levels

 

Strengthen technology research and development ​


Water filter manufacturers should continue to increase investment in technology research and development, and strive to develop water filters with self-cleaning functions. By setting up an automatic cleaning device inside the Self Cleaning Water Filter, the filter element and pipeline can be deep cleaned regularly, greatly reducing the user's maintenance workload. In addition, the development of new filter element materials is also a key direction. New materials should have stronger anti-pollution ability and longer service life, thereby reducing the frequency and difficulty of cleaning and maintenance of water filters. ​


Establish a complete after-sales service system ​


Manufacturers and sellers should work together to establish a comprehensive and multi-level after-sales service system. On the one hand, set up a special after-sales service hotline and online customer service platform to ensure that users can get timely answers to problems encountered during cleaning and maintenance; on the other hand, regularly organize professional technicians to provide users with on-site inspection and maintenance services, timely discover and solve potential problems of water filters, and ensure that water filters are always in normal operation. ​
Proper cleaning and maintenance of water filters is not only related to the user's water safety, but also directly affects the service life of the equipment. All parties in the industry must work together to improve standards and specifications, enhance technical levels and service quality, create a better and more efficient water filter experience for users, and jointly promote the healthy and sustainable development of the water filter industry.
