Subject | Regulation to limit Ozone emissions from indoor air cleaning devices |
Comment | To: California Air Resource Board RE: Proposed Regulation to Limit Ozone Emissions from Indoor Air Cleaning Devices ClearWater Tech is a manufacturer of Ozone generators located in San Luis Obispo, Ca. We support the need to regulate indoor Ozone generators and are in agreement with the proposed regulation as written. The comments we have concern the UL test procedure. 1) The room that the device is tested in needs some amount of air exchanges or it will not be a realistic test. The test calls for 0 to 0.35 changes /hr. We would propose that the spec be 0.2 to 0.35 changes/hr. Reason. A room that has no air exchanges over a 24 hour period would be most likely unbearable for a human. 2) The test room should have some sort of typical household material placed in it such as carpet, drapes or upholstery material. Reason: In a normal room occupied by humans, these materials would be present. 3) The Ozone level in the room should be monitored at a greater distance than two inches from the product. We suggest at least two feet. Reason: We can't imagine someone putting his or her face 2 inches from an Ozone generator for 24 hours.
