Internet Sales Statement

For over 75 years, Nu-Calgon has a long-standing history of being the leader in the HVAC industry in specialty chemicals and Indoor Air Quality products. Nu-Calgon products are not consumer products and are intended for application and use only by professional contractors. Serious personal injury and equipment damage may result from their improper application or use or from the failure to follow a product’s specifications and instructions. Accordingly, our products should be applied or used only by a professional contractor.

Nu-Calgon sells our products directly to authorized HVACR wholesalers who in turn sell them to professional contractors. It is the wholesaler’s responsibility to sell it to trained professionals. Nu-Calgon does not sell iWave® or other Nu-Calgon products online to contractors, dealers, or consumers. If you see an iWave product being offered for purchase on a consumer website, then it is being sold by an unauthorized seller and does not come with a warranty. In addition, when buying from an unauthorized dealer, we cannot guarantee the legitimacy of the product, since there are companies trying to copy iWave products and sell them as original OEM items.

 iWave Warranty: iWave products include a three-year warranty only if purchased from an authorized dealer and installed by a professional HVACR contractor.

 If you have a question on the authenticity of an iWave product or seller, please contact us at
