Guidelines for U.S. ETL Certification UL Certification and CPSC Certification for Drinking Water Filters

Drinking water filter Purified water Tap water filter is a device for purifying water, which is a kind of small household appliances, but there are also relatively large filter devices that are generally used in factories and companies where there is a large demand for purified water to treat water. It is divided into primary treatment (removal of larger impurities and particles), secondary treatment (removal of peculiar smell, organic matter and other impurities in the water), tertiary treatment (reducing the hardness of water and making people drink softer), and fourth-level treatment. Called fine treatment, it uses hollow fibers with a filtration accuracy of 5μm to continue to purify the water quality and extend the service life of the protective membrane. There is also membrane separation: usually select one to two filter membranes, including microfiltration (MF), sodium filtration (NF), ultrafiltration (UF), reverse osmosis (RO), etc. The process is different according to the user’s water quality It is required to select the type of membrane, in which reverse osmosis can effectively remove salt and organic matter.

The basic information and composition of drinking water filter purifiers are introduced above. Here, if drinking water filters are to be exported to the US and North American markets, not all ETL certifications, UL certifications and CPSC certifications are required. If they are circulated in the North American market, they will be done. ETL certification is sufficient. Generally, if the pure water filter of drinking water filter is to be sold in the US market, you can choose to do UL certification and CPSC certification, and many people know that UL certification is a non-mandatory certification in the United States, but ETL certification and CPSC certification are required What has to be done, ETL certification and UL certification are all certifications for small household appliances, power tools, home appliances, telecommunications and IT/AV products, components, lamps, HVAC, medical equipment, toys and other products. There are two ways to do ETL certification for drinking water filters. One is to transfer the CB test report, and the other is to directly apply for the test for ETL certification. If you pass the CB test report, you also need to apply for a difference test. The product with the ETL certification mark indicates that the relevant product complies with the industry standard of ETL certification and also complies with the relevant product safety standard, and can be used with confidence. Under normal circumstances, BCTC recommends that customers apply for ETL certification, because ETL certification is shorter than UL certification, and it can also be issued first, and then the factory audit can be carried out at the end. However, special attention should be paid to the factory inspection. Basically there are quarters, and of course there will be a certain certificate and license fee. Lamp inspection

The following is the basic process of applying for ETL certification for drinking water filter filters.

1. Fill in the ETL certification test application acceptance form, pay attention to the information inside, please fill in the details

2. Send 1-2 samples to the laboratory to start the formal test: about 1 week

3. If the payment is timely, the test data will be sorted out and the report will be about 3 days later.

4. Witness test: 1 week

5. After the witness test is completed, there is no problem, and the factory will be inspected in about 1 week.

6. The factory inspection has passed the issuance of ETL certification and test reports

Regarding the cost of ETL certification for drinking water filters, what the tester wants to say is that it must be determined based on the test. The fees are generally the same for each laboratory. It is impossible for each testing and certification agency to have the same price for ETL certification. Yes, because each testing and certification agency has different market policies and credibility, the price of ETL certification will also be different. Electromagnetic compatibility test
