Why Replacing Your Filter Matters
A neglected filter cartridge doesn't just affect water clarity — it puts strain on your pump, increases chemical usage, and can lead to costly repairs down the line. Here's what you need to know:
Expected filter lifespan: Approximately 2 years, depending on usage frequency
Cleaning frequency: Remove and rinse your cartridge at least twice per month
Pro tip: Keep a second cartridge on hand so you can swap in a clean one while the other dries — this is the most effective way to maintain water quality without interruption
Drain and refill schedule: Every 1 to 3 months, depending on how often the spa is used. Replace the filter cartridge at every drain
How to Replace Your Filter Cartridge
Step 1: Locate the Filter
The filter cartridge is located on the side of your spa, behind the filter cover.
Step 2: Remove the Old Cartridge
Remove the filter cover, then turn the cartridge counter-clockwise to release it.
Step 3: Rinse the Housing
Before installing the new cartridge, rinse out the filter housing with clean water.
Step 4: Insert the New Cartridge
Place the new cartridge into the housing and turn it clockwise to secure it firmly in place.
Step 5: Replace the Cover
Reattach the filter cover and ensure it is seated properly before restarting your spa.
First fill tip: When filling your spa for the very first time after a filter change, remove the cartridge and insert your garden hose directly into the filter opening. This pushes air out of the pump lines and makes it much easier for your system to prime.
Frequently Asked Questions
What is the original part number for the InnovaSpa filter cartridge?
The original InnovaSpa replacement filter cartridge part number is #105-0509. If this part is out of stock, compatible aftermarket replacements include the Pleatco PGS25P4, Unicel 4CH-24, and Filbur FC-0131.
How often should I replace my hot tub filter cartridge?
Under normal use, a filter cartridge lasts approximately 2 years. However, you should clean it at least twice a month and replace it whenever you notice reduced water flow, cloudiness, or visible deterioration of the filter media.
Can I use my spa while the filter is being cleaned?
Yes — this is exactly why we recommend keeping two cartridges. Swap in your clean, dry cartridge while you wash and dry the other one. Never run your spa without a filter cartridge installed, as this can damage your pump.

- Expected filter lifespan: Approximately 2 years, depending on usage frequency
- Cleaning frequency: Remove and rinse your cartridge at least twice per month
- Pro tip: Keep a second cartridge on hand so you can swap in a clean one while the other dries — this is the most effective way to maintain water quality without interruption
- Drain and refill schedule: Every 1 to 3 months, depending on how often the spa is used. Replace the filter cartridge at every drain
How to Replace Your Filter Cartridge
Step 1: Locate the Filter
The filter cartridge is located on the side of your spa, behind the filter cover.
Step 2: Remove the Old Cartridge
Remove the filter cover, then turn the cartridge counter-clockwise to release it.
Step 3: Rinse the Housing
Before installing the new cartridge, rinse out the filter housing with clean water.
Step 4: Insert the New Cartridge
Place the new cartridge into the housing and turn it clockwise to secure it firmly in place.
Step 5: Replace the Cover
Reattach the filter cover and ensure it is seated properly before restarting your spa.
First fill tip: When filling your spa for the very first time after a filter change, remove the cartridge and insert your garden hose directly into the filter opening. This pushes air out of the pump lines and makes it much easier for your system to prime.
Frequently Asked Questions
What is the original part number for the InnovaSpa filter cartridge?
The original InnovaSpa replacement filter cartridge part number is #105-0509. If this part is out of stock, compatible aftermarket replacements include the Pleatco PGS25P4, Unicel 4CH-24, and Filbur FC-0131.
How often should I replace my hot tub filter cartridge?
Under normal use, a filter cartridge lasts approximately 2 years. However, you should clean it at least twice a month and replace it whenever you notice reduced water flow, cloudiness, or visible deterioration of the filter media.
Can I use my spa while the filter is being cleaned?
Yes — this is exactly why we recommend keeping two cartridges. Swap in your clean, dry cartridge while you wash and dry the other one. Never run your spa without a filter cartridge installed, as this can damage your pump.
My model isn't on the list. Can you still help?
Absolutely. Western Tub and Pool specializes in hard-to-find spa parts. If your model isn't listed, contact us directly — our team can help you identify the correct part based on your spa's make, model, and serial number.

Do you ship across Canada and the US?
Yes. Contact us directly to confirm availability and shipping options for your location. Browse our full catalogue online or call us for assistance.
What happens if I use the wrong filter cartridge?
