★The fourth-generation all-powerful sewage discharge patented technology, which integrates the most advanced sewage discharge technology: open the large particle impurity discharge port in the forward rotation to flush the large particle impurity;

★Matrix suction cup linear siphon technology, reverse to strengthen the siphon effect, and solve the particle impurities embedded in the filter;

★The upgrade of the double-sided magic scraper technology makes the scraping silicon strip closer to the surface of the filter screen and the inner wall of the filter bottle, and it can easily discharge the sewage through the positive and negative rotation, and discharge the sewage more thoroughly;

★The filter bottle adopts original imported materials, does not contain bisphenol A, and has passed NSF and SGS testing. After BSK's modified formula, it can withstand the freezing test at -30℃; the burst pressure is more than 60 kg, and the water hammer is 12 kg. More than 150,000 times; exceeding NSF pipeline standards;

★European patented appearance, novel and high-grade;
