11% of our Service Calls are caused by dirty filters --- and we feel absolutely terrible charging a client a Service Call for something so simple. As a service to you we have created an easy to use filter change reminder. Just select the date and enter your information and you will automatically receive an email each month as a friendly reminder to change your filter. Don't worry your email is safe and will not be given out to anyone. You can remove yourself from this filter change reminder service at any time.
