The critical aspects of filter sizing and a methodology for predicting a filter's performance against allergens, bacteria and viruses are presented. The use of 80- and 90-percent filters produces air-quality improvements that approache those with HEPA filters. The combination of filtration and UVGI offers an efficient way of controlling both the largest microbes and spores and the smallest bacteria and viruses.
