How to Clean A Hot Tub Filter?

22 minutes read

Cleaning a hot tub filter is essential to ensure proper water circulation and filtration, maintaining the water quality. Here are the steps to clean a hot tub filter:

  1. Turn off the hot tub: Before starting the cleaning process, make sure the hot tub is turned off and unplugged. This ensures your safety and prevents any damage to the filtration system.
  2. Remove the filter: Locate the filter compartment, usually found somewhere near the hot tub pump. Open the compartment and carefully remove the filter from its housing.
  3. Rinse with water: Using a garden hose or tap water, rinse off any loose debris or dirt from the filter. Ensure you rinse both the inner and outer portions of the filter thoroughly.
  4. Soak in filter cleaner: Prepare a bucket or container filled with hot water and a recommended filter cleaning solution. Submerge the filter completely in the solution and let it soak for the suggested time indicated on the cleaning product.
  5. Brush off debris: After the soaking period, use a soft brush to gently scrub the filter, focusing on areas with stubborn dirt or buildup. Be thorough but avoid using excessive force as it may damage the filter.
  6. Rinse again: Once the brushing is complete, rinse the filter again with water to remove any remaining cleaning solution and dislodged debris. Ensure all the cleaning solution has been removed to prevent any issues when reinstalling the filter.
  7. Air-dry the filter: Shake off excess water from the filter and allow it to air-dry completely before reinstalling it. Placing the filter under direct sunlight can help speed up the drying process.
  8. Reinstall the filter: Once the filter is dry, carefully place it back into its housing, following the manufacturer's instructions. Ensure a proper fit to prevent any leaks or gaps.
  9. Restart the hot tub: After the filter is securely installed, close the filter compartment and restart the hot tub. Allow the water to circulate for a few minutes to ensure everything is back to normal.


It's important to note that the frequency of cleaning your hot tub filter depends on usage and the manufacturer's recommendations. Regular filter maintenance is necessary to keep your hot tub running efficiently and to enjoy clean, clear water.

What are the benefits of a clean hot tub filter?

There are several benefits of a clean hot tub filter:

  1. Improved water quality: A clean filter helps to remove debris, contaminants, and impurities from the water, resulting in cleaner and clearer water. It helps to maintain the water balance and prevents the growth of bacteria and algae.
  2. Enhanced filtration efficiency: A clean filter allows for better water circulation and filtration. It can trap smaller particles and pollutants, improving the overall effectiveness of the filtration system.
  3. Extended equipment lifespan: A clean filter reduces strain on the hot tub's pump and other mechanical components. By preventing debris from clogging the system, it helps to maintain optimal performance and promotes longevity.
  4. Increased energy efficiency: When the filter is clean, the hot tub's pump doesn't have to work as hard to circulate the water, resulting in energy savings. It can contribute to lower electricity bills and reduced environmental impact.
  5. Better water flow and pressure: A clogged or dirty filter can restrict water flow and decrease water pressure in the hot tub. A clean filter allows for better water circulation, creating a more enjoyable and relaxing experience.
  6. Lower maintenance requirements: Regularly cleaning the filter reduces the frequency and intensity of other maintenance tasks, such as adding chemicals or draining and refilling the hot tub. It helps to keep the water balanced and reduces the need for excessive manual intervention.
  7. Health and safety: Clean water is crucial for bathers' health and safety. A clean filter helps to remove bacteria, viruses, and other harmful microorganisms, promoting a hygienic environment for hot tub users.


Overall, maintaining a clean hot tub filter is essential for optimal performance, water quality, and the longevity of the hot tub and its equipment.


Should I clean my hot tub filter before or after using chemicals?

It is recommended to clean your hot tub filter before using chemicals. Cleaning the filter first will ensure that it is free from debris, dirt, and oils, allowing the chemicals to work more effectively.


How often should I replace my hot tub filter?

It is generally recommended to replace the hot tub filter every 6-12 months, depending on usage and maintenance. However, it is important to regularly clean and maintain the filter between replacements to ensure optimal performance and longevity.


How do I remove the hot tub filter for cleaning?

To remove a hot tub filter for cleaning, follow these steps:

  1. Turn off the power supply to the hot tub to prevent any accidents.
  2. Locate the filter compartment. It is typically situated near the water intake or in the equipment area of the hot tub.
  3. Open the filter compartment cover or door. This may require unscrewing or unlatching, depending on the design of your hot tub.
  4. Inside the filter compartment, locate the filter cartridge or element. This is the component that needs to be cleaned or replaced.
  5. Depending on the type of filter, there may be a locking mechanism holding it in place. Release any clips or locks to free the filter.
  6. Gently pull the filter out of its housing, being cautious not to damage or break any connecting parts.
  7. Once the filter is removed, inspect it for any visible debris or dirt build-up. If the filter is made of fabric or pleats, use a hose to rinse off loose debris before cleaning it thoroughly.
  8. Fill a bucket or basin with water and add a filter cleaner solution specifically designed for hot tub filters. Follow the instructions on the cleaner packaging for the correct ratio of cleaner to water.
  9. Place the filter inside the solution and allow it to soak for the recommended amount of time, usually around 1-2 hours.
  10. After the soaking period, thoroughly rinse the filter with a hose to remove the cleaner solution and any remaining debris.
  11. Inspect the filter for any signs of damage or excessive wear. Replace the filter if necessary.
  12. Once the filter is clean and dry, reinsert it into the filter compartment, ensuring it is properly aligned with any directional arrows or markings.
  13. Lock the filter into place by securing any clips or locks.
  14. Close the filter compartment cover or door, and ensure it is tightly sealed.
  15. Turn the power supply back on and allow the hot tub to resume its regular operation.


Remember to regularly clean or replace your hot tub filter as recommended by the manufacturer to maintain proper water circulation, filtration, and overall performance.


What tools do I need to clean a hot tub filter?

To clean a hot tub filter, you will need the following tools:

  1. Bucket or container: Use a bucket or container to hold water and cleaning solution while you clean the filter.
  2. Water hose: You'll need a hose to rinse off the filter and remove any debris.
  3. Filter cleaning solution: Purchase a filter cleaning solution specifically designed for hot tub filters. Avoid using regular household cleaners or bleach, as they can damage the filter.
  4. Soft brush or filter cleaning wand: A soft brush or specialized filter cleaning wand can be used to scrub away dirt and debris from the filter pleats. Avoid using a stiff brush, as it may damage the filter material.
  5. Rubber gloves: It's always a good idea to wear rubber gloves to protect your hands from any potentially harsh cleaning chemicals.
  6. Replacement filters (optional): If your filter is old or damaged, you may want to have a replacement filter on hand to install after cleaning or to rotate between cleanings.


What happens if you don't clean a hot tub filter?

If you do not clean a hot tub filter regularly, it can lead to various issues and affect the overall performance of your hot tub. Here are some potential consequences:

  1. Diminished water quality: The filter's main function is to capture and remove debris, contaminants, and impurities from the water. If the filter is not cleaned, it will become clogged and less effective at removing these particles, resulting in poorer water quality. The water may become cloudy, dirty, or develop unpleasant odors.
  2. Reduction in water circulation: A clogged filter restricts water flow through the hot tub system. This can lead to a decreased water circulation, affecting the distribution of heat and chemicals and potentially leading to uneven water temperature. Inadequate circulation also means that the water may not reach all the areas in the tub, resulting in stagnant or stagnant areas with poorer water quality.
  3. Overworked pump and increased energy consumption: When the filter is dirty, the pump needs to work harder to push water through the obstructed filter. This increased workload can strain the pump motor, potentially leading to premature wear and tear, increased energy consumption, and higher electricity bills.
  4. Filter damage and reduced lifespan: Over time, a neglected filter can become damaged due to the accumulation of debris and contaminants. The increased pressure and strain on the filter can cause tears, cracks, or even complete failure. This can result in the need for a replacement filter, which adds to the maintenance cost.
  5. Hinderance in chemical balance: The filter plays a crucial role in maintaining proper chemical balance in the hot tub. A dirty filter can struggle to retain and distribute chemicals effectively, leading to imbalances in pH levels and sanitization. This can allow bacteria, algae, or other harmful microorganisms to thrive, posing potential health risks for hot tub users.


To avoid these problems, it is important to clean and maintain your hot tub filter according to the manufacturer's recommendations. Regular cleaning or replacement will help ensure optimal performance, longer filter lifespan, and a healthier and more enjoyable hot tub experience.
