TO WHOM IT MAY CONCERN,

Dynamic electronic air cleaners seem to be effective filters for the removal of airborne particles, including smoke. Based on feedback from my allergy patients who have installed this filter, it has been a valuable adjunct in the treatment of their allergic symptoms. The filter's effectiveness in removing cigarette smoke has been demonstrated to me and was quite impressive.

I am not in the position to compare Dynamic electronic air cleaners with other air cleaners based on the information I have available to me. For this reason, I am not in a position to recommend one filter over another. I am able to say, however, that Dynamic electronic air cleaners have been a valuable adjunct in the -treatment of allergic disorders for the few patients of mine that have used them.

To Whom It May Concern:

We at St. John's have used the Dynamic ail filter system for the past four years. This system was supplied and applied by the Electronair Co. Ltd.

The purpose of using it was to reduce the number of smells that filtrated this facility and we are pleased to confirm that we are extremely satisfied. Ever since the application we have had no complaints from both staff and patients about the air quality in the building.

I can only therefore suggest that the use of these units may also have a similar effect in other building envelopes.

Yours truly,
