How to Clean Hot Tub Filter?
Proper maintenance of your hot tub involves more than just balancing chemicals and checking water levels—it also requires regular cleaning of the filter. A clean filter is crucial for keeping your hot tub water clear and safe, as it helps trap debris, oils, and other contaminants.
If you’re unsure how to clean hot tub filter, don’t worry—this guide will walk you through the steps to ensure your filter stays in peak condition and extends the life of your hot tub.
Why Cleaning Your Hot Tub Filter is Important?
The filter is one of the hardest-working components of your hot tub. It captures dirt, debris, and other particles that can cloud the water or damage the hot tub’s equipment. Without a clean filter, the water becomes dirty more quickly, and the strain on your hot tub’s pump and heater increases. Regularly cleaning the filter helps maintain water quality, extends the life of your hot tub components, and reduces the frequency of water changes.
Maintaining Water Clarity
One of the primary functions of the filter is to keep the water clear. When the filter is clogged with dirt and oils, it can’t function properly, and your hot tub water may turn cloudy or discolored.
Reducing Wear on the Hot Tub
A dirty filter forces the pump to work harder, leading to increased wear and tear on the motor. Over time, this can lead to costly repairs or a shortened lifespan for your hot tub.
How Often Should You Clean a Hot Tub Filter?
Cleaning your hot tub filter should be part of your regular maintenance routine. As a general rule, it’s recommended to clean the filter every 2 to 4 weeks, depending on how often you use your hot tub. Additionally, you should deep-clean the filter every 3 to 4 months when you drain and refill the hot tub.
Tip: If your hot tub gets heavy use or if the filter appears dirty, clean it more frequently.
Step-by-Step Guide: How to Clean a Hot Tub Filter
Now that you understand the importance of cleaning your hot tub filter, let’s walk through the process. Whether you’re doing a quick rinse or a deep clean, following these steps will help keep your filter in top shape.
Turn Off the Hot Tub
Before removing the filter, turn off the hot tub to prevent the pump from running without a filter in place. This will also ensure your safety while handling the filter.
Remove the Filter
Locate the filter compartment, which is usually near the hot tub’s water intake. Carefully remove the filter by unscrewing it or lifting it out of its housing. Be gentle to avoid damaging the filter.
Rinse the Filter with a Hose
For a quick clean, use a garden hose to rinse the filter thoroughly. Spray between the pleats to remove dirt, hair, and debris. Make sure to rinse the filter from all angles, getting rid of as much surface grime as possible.
Tip: Avoid using high-pressure nozzles or pressure washers, as these can damage the filter material.
Soak the Filter in a Cleaning Solution
For a deeper clean, you’ll need to soak the filter in a filter-cleaning solution to remove oils, lotions, and other contaminants that water alone won’t eliminate. You can buy hot tub filter cleaner at most pool and spa supply stores or make a DIY solution using water and vinegar (1 part vinegar to 3 parts water).
- Place the filter in a large bucket or container.
- Fill the container with the cleaning solution until the filter is fully submerged.
- Let the filter soak for at least 8 hours, or overnight, for best results.
Rinse the Filter Again
After soaking, rinse the filter again thoroughly with your hose to remove any remaining dirt and cleaning solution. Be sure to spray between the pleats to get rid of all residues.
Allow the Filter to Dry Completely
Once you’ve rinsed the filter, let it air dry completely before placing it back into the hot tub. This helps prevent mold or mildew from growing inside the filter. If you have a backup filter, you can install the clean, dry one immediately while the original filter dries.

When to Replace a Hot Tub Filter?
Even with regular cleaning, hot tub filters don’t last forever. Most filters need to be replaced every 12 to 18 months, depending on the frequency of use and the type of filter. Here are signs that it’s time to replace your hot tub filter:
- The filter appears discolored or worn.
- The pleats are frayed or torn.
- The water quality isn’t improving after cleaning the filter.
- You notice an increase in pump noise or difficulty maintaining water flow.
Tips for Maintaining a Clean Hot Tub Filter
Regular maintenance is the key to prolonging the life of your filter and keeping your hot tub water in pristine condition. Here are a few additional tips to help you maintain your filter:
- Rotate Filters: If possible, keep a spare filter on hand so that you can rotate between cleanings. This ensures that your hot tub never runs without a filter and gives you time to properly clean and dry the filter before reinstalling it.
- Use a Filter Flosser: A filter flosser is a handy attachment for your garden hose that’s specifically designed to get into the pleats of a hot tub filter and clean them thoroughly.
- Avoid Overloading the Filter: To minimize the workload on your filter, make sure to rinse off before using the hot tub to remove oils, lotions, and dirt. You can also use a scum ball or sponge in the hot tub to absorb oils and reduce buildup on the filter.

Whether you’re doing a quick rinse or a deep soak, regular filter maintenance helps extend the life of both your filter and your hot tub.
