What are hot tub filters?

Hot tub filters are essential components of your hot tub's filtration system. They help remove debris, particles, and contaminants from the water, ensuring clean and clear water for a relaxing and enjoyable hot tub experience. Filters trap dirt and impurities as water passes through them, preventing them from re-entering the hot tub.

Why do I need to replace my hot tub filters?

Hot tub filters require regular replacement to maintain optimal performance and water quality. Over time, filters can become clogged with debris and lose their effectiveness. A dirty or worn-out filter can strain the hot tub's circulation system, leading to poor water quality and potentially damaging the hot tub equipment. Regular filter replacements help ensure efficient filtration and clean water.

Which hot tub filter do I need?

The compatible filters for your hot tub varies based on the brand and year. We recommend checking out our free Filter Finder tool, which helps you find the right filter for Jacuzzi, Sundance Spas, Sunrise, Nordic hot tubs and more.

How often should I clean or replace my hot tub filters?

The frequency of cleaning or replacing your hot tub filters depends on several factors, including usage, water conditions, and the type of filter. As a general guideline, it's recommended to clean your filters every 1-2 weeks and replace them every 6-12 months. However, it's important to monitor the filter's condition and performance regularly. If the filter appears dirty or worn, or if water quality issues arise, it may be time for cleaning or replacement.

How do I clean my hot tub filters?

Cleaning hot tub filters involves rinsing off debris and contaminants from the filter surface. Start by removing the filter from the hot tub and rinsing it with a hose to remove loose debris. Use a filter cleaning solution or a mixture of water and a mild filter cleaner to soak the filter. Gently scrub the filter with a soft brush to remove any remaining dirt. Rinse the filter thoroughly with clean water and allow it to dry completely before reinstalling it in the hot tub.
