How do you clear outdoor air pollution with small sized air cleaners? The share volume of contaminated air and weather conditions makes that a dream. Even small areas is almost impossible in an outdoor setting. You can blow cleand air on the recipient but you can’t continuously protect an area that’s out door in a polluted outdoor environment. I find Praan homepage to be very un informative on what specific methods you are using. The technology is not shown and test data not shown either. What grade of air filtration do you compare with? ePm2.5 is seen only once. What hepa filter grade are you comparing with? Why is there no pricing on the page? It’s story telling and a lot of investor information, but very little actual data on the technology and products.
