  • The COVID buster device invented by a high school student uses the concept of heat to destroy the virus in the air via the safest way
  • It now has an upgraded version which utilizes a flat iron other than rice cooker
  • The newest variation is ideal in a hospital setting because of its higher temperature heating capacity

Last May, Francis Daimler Tabag, a Filipino high school student invented a COVID buster device that aims to eliminate the virus in the air safely. This device may address the recent report of the WHO that COVID -19 is airborne and can stay up to 8 hours in the air.

The design

The invention is composed of simple materials readily found at home and uses the concept of heat to disinfect the air. This time, the young scientist has upgraded his prototype by using a flat iron instead of a rice cooker to produce heat. The iron is attached to the bottom with its soleplate facing upward. It is turned on at the highest temperature (1000 watts) when in operation. The fan can also be set in three variable speeds to produce the desired temperature and volume of airflow.

According to the findings of the World Health Organization, “Heat at 56°C kills the SARS coronavirus at around 10000 units per 15 min (quick reduction).” With that in mind, Tabag built the device with the help of his father, Genaro, an experienced engineer.

How it works

When the fan is turned on, the air is sucked into the funnel. It contacts with the superheated soleplate of the flat iron or rice cooker. This destroys the virus. The purified air is then pulled upward.

Genaro Tabag said that most domestic irons can warm up from 121 °C to 182 °C  but sometimes can even reach up to 220 °C.

Because of its better heating capacity, Tabag advises the use of iron in a hospital space good for  20 persons while the rice cooker is ideal for residential houses with more or less 10 persons.

Based on their experiment, we only need 30 minutes to 1-hour operation using the rice cooker design while 15-45 minutes with the flat iron.

The father-and-son tandem is doing more experiments to ensure their product is consistently effective. They plan to present it to the Department of Science and Technology for evaluation very soon.

What do you think? Is their invention promising?
