The main component is reverse osmosis membranes with a pore diameter of 0, 0001 microns. No virus can get through such tiny holes. The membrane itself separates water into pure and concentrate. The clean one gets to you in a cup, pot or bathroom, and the concentrate goes to the drain along with all the viruses. The price is 1,000 shekels.
Take care of your health. It's time to drink clean water!
