Wearing a Portable HEPA air purifier with nasal mask is more comfortable than not wearing it September 06 2022, 15 Comments

Mr. Jing had the first stage of lung cancer in 2021. He told me that wearing a portable HEPA air purifier with nasal mask is more comfortable than not wearing it. The fresh air is suply from the air purifier. He wears it to cooking.

He is living in Shanghai. He never smoke. He told me there are 10 retaird teachers with lung cancer in SUFE (about 500 retired stuff). 

There are HEPA H12 filter and activated carbon filter inside the air filter to treat the air. It can absorb the VOC's, Odor and Smells.
