Aquasana support FAQ

Common questions about manuals, registration, and support for this brand.

  • How often should I replace my Aquasana filters?

    Filter life varies by model and water usage, but it is generally recommended to replace filters every 6 months. Pre-filters in whole-house systems may need replacement sooner if water flow decreases noticeably.

  • How do I contact Aquasana customer support?

    You can reach Aquasana support by calling 866-662-6885 or by emailing support@aquasana.com.

  • Does using non-Aquasana replacement filters void my warranty?

    Yes, Aquasana systems are designed and tested for use with genuine Aquasana parts. Using parts from other manufacturers may result in system failure or leaks and will void your warranty.

  • Do I need a plumber to install my Aquasana system?

    Many under-sink and shower filters are designed for DIY installation. However, whole-house systems often require cutting into main water lines, and professional installation by a licensed plumber is recommended.

  • What is the warranty coverage for Aquasana products?

    Aquasana offers a limited warranty that covers defects in materials or workmanship. The duration depends on the specific model (e.g., 1 year for some components, up to 10 years for certain tanks). Proof of purchase is required.
