Can special negative ion tiles really purify the air?

Compared with ordinary ceramic tiles, negative ion ceramic tiles have negative ion functional layers, and the functional layers are patented, and natural rare minerals (tourmaline) and other raw materials are added. Natural mineral raw material (tourmaline) forms electromagnetic field, which can excite ions in the air, thus producing a large number of negative air ions, thus achieving the effect of purifying the air. If you want to buy negative ion tiles, you can look at the special negative ion tiles, because negative ion tiles were invented by this brand.
