This breath filter, which brings you 99.99% CLEAN air, is 100% designed and produced by HANSEN Mold. It protects both you and others.  Here's how it works:

1. if there's virus in the air, when you breath in, the filter element on the filter will absorb the virus to ensure that you are breathing clean and fresh air.

2. if you are infected by COVID or other virus, when you breath out, The filter on the other straw will absorb the viruses you exhale, keeping others safe.

This breath filter can not only be used during the pandemic, but people can keep several at home in case fire occurs, this way people have a much higher chance of surviving a fire.
