How to Clean and Replace Your Spa Pool Filter: Step-by-Step Instructions
Your spa filter is essential to keeping your water clean, clear, and safe. It traps debris, oils, and contaminants, helping your spa’s pumps and sanitising system work efficiently. This guide explains how to clean and replace your spa pool filter properly so you can enjoy healthy water and extend the life of your spa.
1. Why the Filter Matters
The filter plays a key role in your spa’s circulation system. When it’s clean, water flows easily through the jets and heater. When it’s dirty or clogged, your spa may experience:
Cloudy or dirty water
Reduced jet pressure
Heater shutoffs or error messages
Extra strain on pumps and components
Routine filter maintenance is simple but makes a big difference in spa performance and longevity.
2. How Often Should You Clean the Filter?
Use this general timeline as a guide:
Rinse every 1 to 2 weeks using a garden hose to remove surface debris
Deep clean every 1 to 2 months using a spa filter cleaner to break down oils and residue
Replace every 12 to 18 months, or sooner if the filter shows signs of wear or damage
If your spa sees heavy use or many bathers, increase the frequency of cleaning.
3. How to Rinse Your Filter
For regular upkeep, a simple rinse can go a long way:
Turn the pool to low or off on the touchpad
Remove the filter from its housing.
Rinse the filter with a strong stream of water from top to bottom.
Rotate as you rinse to reach between pleats.
Let the filter air dry before reinserting, or replace with a spare while drying.
Avoid using high-pressure washers, as they may damage the filter media.
4. How to Deep Clean Your Filter
A deep clean removes oils, lotions, and fine particles that a rinse can’t fully address:
Fill a clean bucket with water and spa filter cleaning solution.
Soak the filter for several hours (or overnight for heavy buildup).
Rinse thoroughly with clean water to remove all chemical residue.
Allow to dry before placing it back in the spa.
Always use a cleaner designed for spa filters, household detergents can cause foaming and chemical imbalances.
5. When and How to Replace Your Filter
Even well-maintained filters wear out over time. Replace your filter if you notice:
Frayed or flattened pleats
Persistent cloudy water despite cleaning
A musty or sour smell
Discoloration or cracking of the core
To replace your filter:
Turn the pool to low or off on the touchpad
Remove the old filter and inspect the housing for debris.
Insert the new filter in the same orientation.
Restart the spa and check for proper flow.
Be sure to choose a filter that matches your spa model. If unsure, contact the manufacturer or supplier for guidance.
Final Thoughts
Keeping your spa filter clean and replacing it on schedule is one of the easiest ways to protect your investment. It helps maintain clear water, efficient performance, and a comfortable soaking experience. With a little routine care, your spa stays in top condition, and you spend less time troubleshooting.
