| Just how truly effective is the Sonic Dry Clean
System? Independent research conducted by California Environmental
Engineering, an environmental testing laboratory in Anaheim,
California concluded that:
"THE SONIC DRY CLEAN METHOD IS AN EFFICIENT, FAST AND
COST EFFECTIVE WAY TO CLEAN AIR FILTERS… IT IS EVIDENT
THAT THIS PROCESS WILL EXTEND THE LIFE OF AIR
|
FILTERS WHILE AT THE SAME TIME LOWER MAINTENANCE
COSTS."
California Environmental Engineering performed extensive tests
on a variety of filters. All the filters were weighted and flow
checked (using a manometer) prior to testing, and to simulate
clogging the laboratory poured dry powdered paint
down the side of each filter, turning them to completely coat the
filter surfaces. The filters were then flow checked again.
The next step was to clean all the filters using the Sonic Dry
Clean System, and when the cleaning was complete, the filters were
re-weighed. Overall,
|
the study found that the
precoat on the filters added 2.0% to their original weight.
It is also important to note that the Sonic Dry Clean System
does not remove the protective cake of dust, or, "precoat" that has
collected on the filter media during its early life. Consequently,
the air filter is operating at maximum efficiency after the
cleaning process, and that's better than a new filter!
