Hot Tub Filter Replacement Guide: When and How to Replace Filters

Maintaining clean and clear water in your hot tub largely depends on how well your filters are functioning. Over time, hot tub filters can become clogged with dirt, oils, and debris, which reduces their effectiveness. To keep your spa running smoothly, it's crucial to replace your hot tub filters regularly. In this guide, we’ll walk you through when and how to replace your hot tub filters to ensure peak performance.

When Should You Replace Your Hot Tub Filters?

The general recommendation is to replace your hot tub filters every 12 to 24 months, depending on usage and maintenance. However, there are several factors that can affect how often you should replace your filters:

• Frequency of use: If you use your hot tub frequently, the filters will wear out more quickly and may need to be replaced closer to the 12-month mark.
• Water quality: Poor water quality or improper chemical balance can lead to faster filter degradation, meaning you may need to replace them sooner.
• Cleaning habits: Regularly cleaning your filters can extend their lifespan, but eventually, they’ll need to be replaced even with proper care.

Signs It’s Time to Replace Your Hot Tub Filters

Aside from keeping track of the time, there are a few telltale signs that your filters need to be replaced:

• Water clarity issues: If your water looks cloudy or murky even after balancing chemicals, the filter may not be doing its job effectively.
• Reduced water flow: If the jets are weaker than usual or the water circulation seems poor, the filter may be clogged or too worn to work properly.
• Filter damage: If the filter’s pleats are cracked, frayed, or torn, it’s time to replace it immediately to avoid further issues.

How to Replace Your Hot Tub Filters

Replacing your hot tub filters is a straightforward process. Here’s a step-by-step guide to help you get it done:

Step 1: Turn Off the Power

Before you begin, make sure to turn off the power to your hot tub. This will prevent any potential damage to the system while you’re working on the filters.

Step 2: Remove the Filter

Locate the filter compartment, which is usually near the pump or on the side of the hot tub. Remove the filter by unscrewing it or pulling it out, depending on your hot tub model. Be sure to inspect the filter for any visible damage.

Step 3: Clean or Discard the Old Filter

If the filter is still in relatively good condition but just dirty, you can clean it with a filter cleaner to extend its lifespan. However, if the filter is showing signs of wear or damage, it's time to replace it with a new one. For top-quality filters and cleaning supplies, check out the AquaDoc Hot Tub Care Collection.

Step 4: Install the New Filter

Take your new filter and carefully install it in place of the old one. Make sure it's securely positioned before turning the power back on.

Step 5: Test the Water Flow

After the filter is installed, turn the power back on and test the water flow through the jets. If the water flows smoothly and the jets are functioning properly, your new filter is installed correctly.

How Often Should You Clean Hot Tub Filters?

In between replacements, it's important to regularly clean your filters to keep them working effectively. Here are some general guidelines:

• Rinse the filter: Once a week, remove the filter and rinse it with a garden hose to remove dirt and debris.
• Deep clean: Once a month, soak the filter in a cleaning solution to remove any oils, lotions, or other contaminants.
• Full replacement: Even with proper cleaning, you should still replace your filters every 12-24 months for optimal performance.

Choosing the Right Replacement Filters

Not all hot tub filters are created equal, so it’s important to choose the right one for your spa. Make sure the replacement filter matches the size and specifications of your current filter. If you’re unsure which filter to choose, consult your hot tub’s manual or contact a professional for guidance.
