How To Clean Hot Tub Filter?


The Importance Of Cleaning Your Hot Tub Filter

Owning a hot tub is a luxury that many people enjoy. It offers relaxation, hydrotherapy, and a great way to spend time with friends and family. However, to ensure the longevity and optimal performance of your hot tub, regular maintenance is crucial.

One of the most important maintenance tasks is cleaning the hot tub filter.

Why Regular Cleaning Is Necessary:

  • Efficient filtration: The hot tub filter is responsible for removing debris, dirt, and contaminants from the water. Over time, these particles accumulate and can clog the filter, making it less effective. Regular cleaning ensures proper filtration and allows the water to stay clean and clear.
  • Preventing bacteria growth: When a hot tub filter becomes dirty, it provides a breeding ground for bacteria and other microorganisms. These can not only affect the quality of the water but also pose a health risk to users. Cleaning the filter regularly helps prevent bacterial growth and maintain a healthy and safe environment for soaking.
  • Optimal water circulation: A dirty filter restricts the water flow in the hot tub. This can lead to inefficient water circulation, affecting the overall performance of the tub. By cleaning the filter regularly, you ensure proper water flow, which helps maintain consistent heat distribution and improves the overall performance of the hot tub.

The Impact Of A Dirty Filter On Water Quality:

  • Cloudy water: A dirty filter is unable to effectively remove impurities from the water, resulting in cloudy water. This not only looks unappealing but also indicates poor water quality. Cleaning the filter regularly allows for better water clarity, making your hot tub visually more inviting.
  • Chemical imbalance: The accumulation of debris and contaminants in a dirty filter prevents water circulation and inhibits proper chemical treatment. As a result, maintaining the correct chemical balance in the hot tub becomes difficult. Regular filter cleaning helps maintain proper chemical levels, ensuring the water is properly sanitized and safe for use.
  • Reduced equipment lifespan: A dirty filter puts additional strain on the hot tub’s pump, as it has to work harder to circulate water through a clogged filter. This increased strain can lead to premature wear and tear, potentially shortening the lifespan of your hot tub’s equipment. Cleaning the filter regularly alleviates this strain, extending the life of your hot tub components.

Regularly cleaning your hot tub filter is essential for maintaining water quality, preventing bacterial growth, and optimizing the performance of your hot tub. Neglecting this important maintenance task can result in poor water clarity, imbalanced chemical levels, and potential damage to your equipment.


Take the time to clean your hot tub filter regularly to ensure a clean, safe, and enjoyable hot tub experience.

Step-By-Step Guide To Cleaning Your Hot Tub Filter

Maintaining a clean and well-functioning hot tub filter is essential for ensuring optimal performance and water quality. Regular cleaning of your hot tub filter will help prolong its lifespan and prevent any potential issues. Here, we present a step-by-step guide to help you easily clean your hot tub filter.

Shutting Down The Hot Tub:

  • Before you begin the cleaning process, ensure that the hot tub is turned off and disconnected from the power source. Safety should always be a top priority when working on any electrical equipment.

Removing The Filter:

  • Locate the filter housing, usually situated within the hot tub’s equipment area. Gently unscrew and remove the housing cover to access the filter cartridge. Carefully extract the filter by lifting it straight out of the housing.

Pre-Rinsing The Filter:

  • Before proceeding with the deep cleaning process, it is important to remove any loose debris from the filter cartridge. Use a garden hose or a pressure washer on a low setting to rinse the filter thoroughly. Ensure all noticeable dirt and debris are removed before moving on to the next step.

Soaking The Filter In A Cleaning Solution:

  • Prepare a cleaning solution by mixing a filter cleaner specifically designed for hot tub filters with water in a clean bucket or container. Follow the manufacturer’s instructions for the appropriate ratio of cleaner to water. Place the filter in the solution, ensuring it is completely submerged.

Scrubbing The Filter:

  • After allowing the filter to soak for the recommended duration, take a soft-bristled brush and gently scrub the cartridge. Pay close attention to the pleats or folds of the filter, as these are areas where debris may accumulate. Thoroughly clean both the exterior and interior surfaces of the filter.

Rinse And Dry The Filter:

  • Once you have finished scrubbing the filter, thoroughly rinse it with clean water to remove any remaining cleaning solution or dirt. Ensure all traces of cleaning solution are washed away to prevent any potential chemical imbalances in the hot tub water. After rinsing, allow the filter to air dry completely before reinstalling.

Reinstalling The Filter:

  • Once the filter is completely dry, carefully place it back into the filter housing, ensuring it is properly aligned. Screw the housing cover back into place and secure it tightly. Double-check that the filter is securely installed, as improper installation may lead to leaks or reduced filtration efficiency.

By following these simple steps to clean your hot tub filter, you can ensure that your spa remains in top condition, providing you with a clean and enjoyable hot tubbing experience. Regular maintenance and cleaning of the filter will not only extend its lifespan but also contribute to the overall longevity and performance of your hot tub.

  • Deep clean: In addition to regular rinsing, it’s crucial to deep clean your filter occasionally. You can accomplish this by soaking the filter in a filter cleaning solution or using a filter cleaning cartridge. Follow the manufacturer’s instructions for the best results.
  • Rotate filters: If your hot tub has multiple filters, consider rotating them every time you clean them. This will ensure even wear and prolong the lifespan of each individual filter.
  • Replace when necessary: Eventually, every filter will reach the end of its lifespan. As a general guideline, it’s recommended to replace your hot tub filter every 12-18 months, depending on usage and maintenance. Regularly inspect the filter for signs of damage or wear and replace it if necessary.
