What types of high efficiency filters are available?
Several types of high efficiency filters are available that accomplish different tasks and have varying maintenance requirements. There are electronic filters that use 115 volts that primarily target small particulate matter. These are very effective but have to be cleaned monthly to keep its efficiency high. There are also throw-away type 4 or 5 thick media filters that are just as effective as electronic but only have to be replaced once per year. This filter must be installed and maintained with care as they can restrict air-flow over time. On the larger systems two filters may be needed. The highest form of this type of filter is the HEPA (High Efficiency Particulate Arrestance) filter. These filters are replaced every two to three years, however, they are so restrictive they can only filter a potion of the total amount of air going through the system. An additional high efficiency filter may be needed in conjunction with a HEPA filter.
