The pores of the microfiltration membrane are 800 times smaller than the diameter of a human hair The inner surface of the micro-filtration membrane is comparable to an infinitely fine sieve containing billions of pores with a size of 0.05 to 0.1 microns. Pressure is needed to "push" water through these pores. In the J.SHMIDT A500 device, a microprocessor controls the filtration process. It activates a micro-pump to increase the pressure, which automatically equalizes at the end of each filter cycle. This is how we managed to unite the membrane and the activated carbon composite with Aqualen into an efficient and compact combination. Without additional pressure, water would not be able to flow through such a sorption mixture. The replacement module A500 ensures high-quality water purification - removal of chlorine and organo-chlorine substances, heavy metals, scale and iron. In addition, the filter completely retains bacteria and cysts of intestinal parasites without the use of chemical bactericides. Mobile kettle Aquaphor J.SHMIDT A500 with el. indicator is a new generation kettle, designed to protect your health and give you pleasure while using it! Advantages of the product:
