Study on Decomposition of Indoor Air Contaminants by Pulsed Atmospheric Microplasma

Decomposition of formaldehyde (HCHO) by a microplasma reactor in order to improve Indoor Air Quality (IAQ) was achieved. HCHO was removed from air using one pass through reactor treatment (5 L/min). From an initial concentration of HCHO of 0.7 ppm about 96% was removed in one pass treatment using a discharge power of 0.3 W provided by a high voltage amplifier and a Marx Generator with MOSFET s...

Removal of indoor air contaminants by wool carpet

• Polluted indoor air can lead to discomfort, reduced efficiency and even ill health amongst employees and residents in modern buildings. • Wool carpet has been shown to rapidly neutralize formaldehyde, nitrogen dioxide and sulphur dioxide, common contaminants in today's indoor environment. • Not only does wool neutralize these contaminants more quickly and completely than synthetic carpet fibe...

Indoor air contaminants and their impact on respiratory pathologies.

Humans spend a considerable amount of their time breathing air inside enclosed spaces in which, due to various sources, there may be contaminants that deteriorate the air quality. This is an important risk factor for the health of the general population. This review evaluates the contaminants that are present in the air of indoor air spaces, describing the sources that generate them as well as ...

A microfabricated atmospheric-pressure microplasma source operating in air

An atmospheric-pressure air microplasma is ignited and sustained in a 25μm wide discharge gap formed between two co-planar gold electrodes. These electrodes are the two ends of a microstrip transmission line that is microfabricated on an Al2O3 substrate in the shape of a split-ring resonator operating with a resonant frequency of 895 MHz. At resonance, the device creates a peak gap voltage of ∼...
