Over and Beyond Filter Technology Filters were originally designed to protect equipment, not people. Filter technology cannot control airflow, and work best with water and fuel because liquids can be controlled. Filters can only take particles out of the air, up to a certain size, and only those particles that happen to go through the filter. There is no guarantee that all of the air we breathe can be circulated through a filter. Air trapped in corners or cushions goes untreated, as well as bacteria, viruses, mold, mildew, and chemical gases.
Filters collect dirt and dust and, in some cases, even contribute to indoor air pollution.
The cost of filters, alone, can be very expensive to maintain. One time investment with a three year warranty on all parts and labor. This is a completely portable and personal unit. It easily fits into luggage, briefcases and even handbags. It is the perfect personal companion when traveling.
