Good air in &  good air  out: 

Background: This Covid pandemic has cost a lot of lives not only in US but all over the world. It has caused disabilities in people who were infected.

Reasonings: COVID-19 spreads when a patient breathes out droplets containing the virus. When another  person breaths in it will cause the infection. Sometime multiple people get infected. It is rapidly disseminating. Sometimes it is transmitted by touching a contaminated surface. People who are closer to or within 6 feet of the infected person are most likely to get the infection. Covid is transmitted in multiple ways but breathing the air containing the infected viruses is the single most important way of transmitting. On the other hand these droplets containing viruses land on the eyes, face, mouth especially when they splash or spray by sneezing, coughing etc. 

Idea: breathing in good air, breath out good air is the basis of this idea. When you breathe in, the air is filtered by a viral  filter and there’s only one way valves allowing air going in. When a person breathe out the valve will allow the air to scape through another filter so the air going out is free of viruses ‘good air’. The filter will filter 99.999%. 

 Infectivity depends on: 

👉🏿viral load, 

👉🏿duration of exposure, 

👉🏿immunity of the person,  

👉🏿microbial dosage, 

👉🏿genetics of the host, 

👉🏿viral entry route, 

👉🏿strain of the viruses,
