Review on HQUA TWS 12 UV Purifier Sterilizer for Optimal Purification by Kim Lane

It is compact and the inlet and outlet at the end make it easy to install. I gave 4 stars because there is no waterproof connection between the power cord and the lamp. The chance of the glass cartridge assembly breaking is reduced to zero. But a waterproof connection would reassure me. Best of all, a test for the presence of bacteria in the water was carried out five days after installation.
