What is the different between other air cleaner units with built-in ionizer?
Most of the air cleaners with built-in ionizer are not as effective as they only give limited ionizer output unlike Plasma Ion Tower give lots of massive of positive and negative ions in the air and cover much more bigger area. The maintenance cost is high for such air filter units as need to regular change the filter every year or two. Otherwise, the air filter get choke and the unit may consume more energy and not function effectively.
