What are the requirements for optimal air purification?
A decrease or removal of problems caused by indoor air pollution can only be realized if the apparatus meets with certain imperative technical facilities. The most important condition is that all pollutants (particle as well as gaseous) must be eliminated from the air with a high efficiency for prolonged periods of time. There are also other requirements to be met which are discussed hereafter. All requirements must be completely adjusted to each other. 1. Filter specifications. a. Effective Pre-filter to protect the Activated Carbon -filter The pre-filter must be a fine dust-filter with the highest normative results in this class of filters. If these norms are not met the pores of the activated charcoal filter will quickly become choked up whereby the efficiency of adsorption will decrease fast and will even disappear. b. Activated Carbon filter with high adsorption power The activated carbon-filter must have a large adsorption surface in order to work efficiently during a prolonged p
