Residential Air Quality Improvement System

This can be due to poor insulation and ventilation and is made worse when residents cannot afford to heat. The main aim of this paper is to modify an existing dehumidifier that can remove moisture, heat the home and reduce mould and bacteria.

To achieve that we combined the properties of a dehumidifier with ultraviolet germicidal lights (UVGI), which have been proven to effectively destroy the DNA of mould and bacteria. The result shows that the device reduced the mould growth and did increase the room temperature. This is due to the fact that the dehumidifier captured 2 litres of water over 24 hours of testing.
