NSF STANDARD CERTIFIED FOR MATERIAL SAFETY

For the design of carbon block filters, each batch of our orders will be designed and customized according to industry standards or customer requirements, such as formulation, sintering time, temperature and other processes.
In the production process, we must start the aeration test and the 10,000-time pressurization cycle test for each batch of products before putting them into mass production. For the quality control of the finished product, we will carry out process inspection on the performance indexes such as the filtration precision of the product and the removal rate of residual chlorine and other contaminant treatment to ensure that each technical specification of the carbon block filter can meet the requirements of the NSF standard.

OBTAINED NUMBERS OF NATIONAL PATENT TECHNOLOGY ACHIEVEMENTS

As the second generation of activated carbon application technology, the sintered activated carbon filter not only has the adsorption characteristics of granular activated carbon, but also its solid porous structure can play the role of intercepting filtration, which can effectively solve the drawbacks of granular activated carbon charcoal powder falling off and black water. .
With rich experience and technical research, we have been focusing on the development of civil and commercial carbon block water purifiers with international advanced quality standards. In particular, we have in-depth research on the preparation process of sintered activated carbon cartridge and achieved many national patent technology achievements.

THE FILTERING EFFECTS OF HUATAN’S CARBON BLOCK FILTER

As the amount of the use of water increases, the activated carbon block will absorb more and more contaminant.

Through our experimental observations, the filter cartridge will become more and more yellow, and the water output of the purified water

will gradually decrease. These are the proof that our carbon block cartridge effectively filters impurities.

We added Coca-Cola and residual chlorine to the ink as test contaminants, and then poured this reagent into the activated carbon block filter of HUATAN FILTER.

From the above photos, we found that the outer wall of the filter cartridge immediately oozes clear and tasteless water.
