1 .. photocatalyst air purifier is a passive way, can not solve the sources of volatile subject, that is a little volatile pollutants, photocatalytic decomposition point adsorption and photocatalyst body and at the same time in the adsorption of pollutants, so photocatalyst air purifier is just a concept speculation only, no substantive human health on helping; Disadvantages: 1. erosion have some strong oxidizing photocatalyst, metal materials, textile, leather. Weaknesses: will lead to emphysema, air disinfection and even death, can not be of human coexistence, breath slow evaporation air disinfection principle, over at least 30 minutes to enter. 2. Plasma strengths: fast and complete sterilization, air cleanliness reached 300,000 Grade (ISO9 grade scale) or more weakness: there is residual contamination, odor, low disposable purification efficiency 3. UV Advantages: UV can kill a variety of microorganisms, including the multiplication of bacteria, spores, mycobacteria, viruses, fungi, rickettsia and mycoplasma air sterilizer manufacturer, has a broad spectrum. 4. photocatalyst strengths: Sustainable photocatalyst air purification, including the removal of organic and biological contamination. 1. Ozone strengths: a melt bacteria level ozone sterilization method, sterilization thorough, no residue, sterilization broad spectrum. China's current mainstream disinfection technology: VBY-B-type medical air purification and disinfection machine Dongguan Wei an Environmental Technology Limited, the innovative use of semiconductor technology at home and abroad, research and design of the invention air disinfecting machines, most set ionization, ternary semiconductors and lightwave technology into the one of the new air disinfection products, access to national utility model patents (Patent No: ZL 2014 2 0127492.6) and patents (patent: 201410104779.1) which VBY-B type air disinfection products. Air sterilizer manufacturers, Huizhou air disinfection, V1 / Wei one by one Dongguan City Environmental Technology Limited. Dongguan City Environmental Technology Co., a (www.v-1.com.cn) (www.v1xdj.com) strong, credible, environmentally friendly products in Dongguan, Guangdong processing industry has accumulated a large number of loyal customers.
