Sonic is Good Science

Before the Sonic Dry Clean System stood the test in the field, it passed the test at the laboratory. In fact, is was proven that a Sonic Dry Cleaned air filter was more efficient than a brand new air filter!

In a scientific test conducted by California Environmental Engineering, a new air filter, a rebuilt air filter, a wetwashed air filter, and an air filter cleaned by the Sonic Dry Clean process, were compared to determine which filter did the best job of reducing particulate pollution.

The results were simply amazing. The filter cleaned by Sonic Dry Clean was nearly three times more effective in reducing particulate pollution than the wet washed filter; was much more effective than the rebuilt air filter; and was even more effective than the brand new filter. In fact, the brand new filter emitted 15,000 particles per cubic foot more than the air filler cleaned by Sonic.

The reason for this remarkable fact was mentioned earlier: dry cleaning does not remove the filter's precoating, which is the initial layer of contaminants that attaches to the filter and which is necessary for the filter to achieve its highest efficiency. This protective coating is not found on new filters. Thus, an air filter cleaned by Sonic Dry Clean is ready to begin its recycled life at virtual 100 percent efficiency. This means that Sonic Dry Clean is far and away the most effective method of cutting particulate pollution, and staving off fines from regulatory agencies and reducing overhead for its users. And all of this can be achieved at a cheaper price than the cost of a new filter.


A Revolutionary Process

How does Sonic Dry Clean work? First, its specially designed cleaning machine uses computerized sequences of vibration to sonically loosen heavily encrusted particulates. In this part of the process, the air filter is rotated counterclockwise and vibration is created by manipulating air flow. This air vibration vacuums the particulates out of the air filter. The air flow required can easily be provided by a customer's own compressed air source.

The entire process is designed to be done by a single operator, and the average cleaning time for an air filter is less than five minutes.

And so, the Sonic user gets an air filter that is more efficient and in addition to effective in reducing pollution, is less expensive than buying a new one, all in less than five minutes. Now that's efficiency!

No wonder the report issued by California Environmental Engineering said that, "It is evident that [the Sonic Dry Clean] process will extend the life of air filters while at the same time lower maintenance costs."

Scientists Support the Sonic System California Environmental Engineering is not alone in its scientific approval of tile Sonic Dry Clean System. In 1993, the nationally known, highly respected Southwest Research Institute conducted efficiency and dust capacity tests on one new and three dry cleaned air filter elements from Sonic Dry Clean.

The testing was conducted in accordance with the current Air Cleaner Test Code, using the most reliable housing and radial seal testing equipment. Incredibly, the three dry cleaned filters all achieved higher initial and cumulative efficiency levels than the new filter.
