Fears increase the likelihood of contracting the coronavirus floating particles in the air. Earlier this week,239 scientists have signed an open letter at the World Health Organization (WHO), pushing the Agency to recognize theDangers of airborne transmission. Although WHO responded to the letter by noting that there are "emerging evidence" of this possibility, so far, the widely accepted belief was thatCovid-19 is almost always contracted After direct contact with infected respiratory droplets. If you catch the virus of small particles that remain in the air is a significant danger because many experts maintain, then the social distancing measures are not enough to stay safe inside. So what is the solution? A group of researchers recently announced having developed an air filter that can kill 99.8% of coronavirus particles - and it can be on the market soon.

In response to proof that central air conditioning systems can actually diffuse Covid-19, the researchers of the University of Houston psychium tested aFilter that uses heat to kill the virus and published their results in the journalToday physical materials. Conscious that the virus can not survive above a temperature of 70 degrees Celsius (or 158 degrees Fahrenheit), scientists have built a filter with nickel foam, which directs electricity. In super-heating the 200-degree Celsius virus, they were able to eliminate it almost completely "with a single pass through". The filter is also useful for other infectious diseases, including some strains of the flu.

The filter is intended to be placed in existing heating, cooling and ventilation systems, which would be more profitable for schools, hospitals, businesses and even homes than replacing them completely.Zhifeng Ren, Director of the University Texas Center for Superconductivity and one of the researchers of the study, saidHouston's Chroniclethisthe filter Do not even add to the energy consumption of a system.

He also told the publication that the filter could be produced for practical use as early as August. Researchers intend high and high-risk traffic areas such as schools and hospitals to first online to buy, but filters may be available for individual consumers after that. And as we learn more and more on airborne transmission, erase airborne particles in as many interior areas as possible to slow down the virus and return to a normal lifetime.

For more than kill Covid,It's the "Goldilocks Zone" where Covid can not survive, the biologist says.
