EnviroSept Electronic Air Cleaners
Air filter manufacturers have their products independently
tested in order to validate claims of performance. Industry wide,
the ASHRAE Test Standard is the method of choice for most types of
The ASHRAE test standards are not specifically designed for any one type of air cleaning device, but at the same time, do not entirely address the variety of air filtering devices and the multitude of applications in which they are used. Filters are designed to capture and hold larger airborne particulate. These tests are designed to measure the total amount of dust holding capacity for a given filter.
Increasingly sophisticated, knowledgeable and informed consumers look for test data so they can make the best possible choice for their filtration requirements. Unlike the standard ASHRAE tests performed on standard disposable filters for arrestence, we conducted efficiency tests for the removal of sub-micron particulate. It is a given that if you can remove the sub-micron particulate, the larger particulate is not a challenge.
The testing was performed in a 1,008 cubic foot test
chamber utilizing laser particle counters to measure the total number
of particles by size. Three separate tests were performed using
pollen, dust, and cigarette smoke.
The following reports summarizes by particle size
the total number of particles counted in a cubic centimeter. The
tests, which lasted from ten to twenty minutes, show the dramatic
reduction in total particles as they are counted at the start of
the test and every two minutes thereafter. After only twenty minutes,
the equivalent of two air exchanges, the "EnviroSept"
removed over 45% of particles in the (0.09 to 0.5 range) and over
77% of the particles in the (.5 to 1.0) micron range. The heating/cooling
systems in most homes normally provide for at least five air exchanges
This testing clearly demonstrates the high efficiency
of the EnviroSept Electronic Air Cleaner and what it may do for
you in your home.
