We are the experts on indoor air quality equipment. Most humidifiers can be easily maintained and repaired by their owners so we have set up this page to assist you in doing so. Our site has owners manuals on-line for MOST models made. Those owners manuals are located on links placed on the specific pages for each individual model. To see if your owners manual is available on-line, click on the appropriate link to the left and keep going until you end up on the specific parts page for your model. Near the top of the parts page for your model you will see a link labeled OWNERS MANUAL. That is a link to a PDF file containing your owners manual. You can use your browsers print feature to make a hard copy for your personal use. The following links will provide you simple to understand answers to 90% of the questions we receive daily from our clients. If you do NOT find your answer on these pages, email us and we will happily answer your question.
