Promotional Materials for Residential Water Treatment Device Certification:  Guidance

NOTE: This page and the linked pages below are for historical reference only, due to statutory changes -- for information about the current Residential Water Treatment Device Program, click here.

Last Update:  January 30, 2010

1. With your application for certification, send draft text, galley proofs or actual copy for labels, product (or performance) data sheet and promotional materials for review.  Do not send final printed material. Changes may be necessary to get your certification.

2. Send all promotional materials, including advertising, packaging, brochures, displays, copy (or tape) for commercials or infomercials. Also submit dealer "how to sell" manuals. Packaging and displays can be photocopied for submittal as long as all copy is included and legible.

3. Don't use the term "remove" without qualifying it with a percentage reduction. If you say "reduces up to" make sure the number you reference is an arithmetic mean calculated in accordance with the testing standard.

4. Don't use generalized claims, e.g., "reduces organic and inorganic chemicals". Even if the literature references the performance data sheet, under-informed dealers can cause problems with this statement.

5. Do not make implied health claims. Do not imply health concerns when making aesthetic performance claims. For example, if the device is only tested to reduce chlorine, stick to the taste and odor claims. Do not reference studies that imply drinking chlorinated water results in a higher incidence of cancer. Also, do not cite health concerns or reference contaminants other than those for which the device is certified.

6. Have a technically qualified person carefully review all promotional materials before submitting them to the State for review. This includes printed, audio and video materials. Also review dealer "how to sell" manuals.

7. Don't use any form of the term "pure" or "purify" in your literature. The terms "treat" and "reduce" are commonly used instead. For a device to be considered a purifier, it must be tested and certified for bacteria, virus and cyst reduction.

8.  CDPH does not have a policy for 'Fits" claims under the registration program.  This issue should be discussed with your certifying organization

9. Don't claim bacteria-reducing capability if your device has been tested for bacteriostatic effect. Bacteria reduction testing must be done according to an approved test protocol.
