Problem Statement
- Air pollutants are generated by nearly every facet of the industrial process, including raw material sourcing, product manufacturing, distribution, and humans need protection from these pollutants for better health.
- Moreover, it has been observed that cold and dehumidified breathing air provides comfort more than the surrounding air.
- In the present invention, an integrated system filters the air to the required level, cools it up to 5 degree Celsius, and provides directly to nostrils neither wasting nor allowing the mixing of unfiltered – unconditioned air.
Technology
The invention provides a personalized breath filter for an individual by using a combination of air filtration, air cooling & dehumidification and personal ventilation.
The device may include a small battery-operated fan for drawing ambient air through the filter mediums (HEPA). Then, the filtered air is outshot through a thermos – electric cooler to cool and dehumidify the air. Further, the conditioned air is supplied to nostrils with an “one-way” air valve for inhaling.
An air reservoir bag of 0.5 liters is positioned between the thermo-electric cooler and inlet on-way valve to reduce the fan size. This ensures longer duration for battery charge and reduces size of the gadget.
Key Features/Value Proposition
- The device consists of a cooler unit, which is connected to face attachment through a connecting line, where the airbag is configured to create a buffer of breathable air to an individual.
- The device has inbuilt storage battery that is portable, and can be operated while on the move providing protection and comfort. Adaptable to scooters and three – wheelers.
- This can be also used with or without cooling system.
