Abstract or Summary

Many New Zealand homes suffer from poor indoor air quality (IAQ). Cold, damp and mould-ridden homes can cause serious respiratory health problems. Poor IAQ can arise due to poor insulation and ventilation, and compounded when residents cannot afford heating. The main aim of this paper is to describe the process and results of modifying an existing dehumidifier to include ultraviolet germicidal UV lights. The modified device was designed to improve ambient air temperature by removing moisture, and perform UV filtration of the air to address mould and bacteria growth. To achieve that we combined the properties of a dehumidifier with germicidal lights (UV), which have been proven to effectively destroy the DNA of mould and bacteria. The results show that the device reduced the mould growth and increased the room temperature.
