There is a new technology based on Nano technology and it is known as Photocatalyst or tio2. This is interesting. It uses light to breakdown air toxin such as: E.Coli, MRSA, Staphs,mold, mildew, bacteria, viruses,SARS, Influenza, tobacco smell, food smell, ammonia, carbon monoxide, Nox, Soxand other smell such as glue, new car scent and others. This is a great news to us all!! You can apply this product directly in your cars, homes, office building with light such as sun light and indoor light to create 3 dimensional air purifier to keep your air clean.
My understanding is that it will never stop working and there is no parts to replace like your typical mechanical air filters that have many filters need it to change and hassle 消毒產品 of changing them and purchasing expensive filters every couple of months.
A friend of my used it, he likes a lot and recommending everyone to try it. He had his car treated and rooms treated. You feels a big difference in his home and cars. His friends also notice the difference in it as well. Photocatalyst is also known as Tio2. This is safe and approved by FDA as it is used in food pigment, sun block, teeth whitening, chewing gum, tooth paste and more.
