Inline HEPA systems – Delivering operating room quality air in your home
More than 99% of the particles suspended in indoor air are less than one micron (0.0000004 inches) in size, far too small to be captured by most types of filters or seen by the naked eye. Particles this tiny have been identified by scientists at the U.S. EPA and elsewhere as potentially “lung damaging”, because they are small enough to bypass our defense mechanisms and lodge deep in our lungs. Our CAP600 Series Central Air Purifiers, with True HEPA filters, are so efficient they can remove at least 99.97% of these microscopic airborne particles (@ 0.3 microns in size), including those that can trigger asthma and other allergic reactions. All Whole-House HEPA Air Cleaners feature multiple filtration stages to remove particles, plus an activated carbon filter to remove odors and some VOC's (Volatile Organic Compounds). Top of the line models are also equipped with germicidal UV (UVGI) or UV "Plus" lamp technology to irradiate and help control bacteria and mold spores present in the air stream or trapped on the HEPA filter. Pads are replaced at the required intervals.
