Proper maintenance of your spa filter cartridges is essential for extending their lifespan. The frequency of cleaning depends on how often you use your spa. Check out our comprehensive guide on cleaning your spa filters and the best products to use.
Clogging of the filter occurs due to soaps, chemicals, sweat, body oils, and fine particles of dust or dirt. When the spa filter cartridge becomes blocked, it can strain the pump and motor, potentially shortening their lifespan.
By following a few simple maintenance steps, you can save money, reduce wear on your spa, and extend the lifespan of your filter. Continue reading to learn how to clean your spa filters.
How do I clean a spa filter?
Step 1: Remove the Filters
Unscrew and remove the filters from your spa’s filter compartment. Take out any floating items, such as scum-absorbent discs or cleaning cloths, as they could be drawn into the pump once the filters are removed.
Step 2: Soak Filters in a Cleaning Solution
For best results, soak your filters for up to 24 hours in a filter cleaning solution. This helps dissolve and loosen accumulated dirt and organic material. Follow the instructions on the filter cleaning product, adding the correct amount to a container of water, and allow your filters to soak. (Longer soaking times are even more effective!)

Step 3: Rinse Filters Using a Filter Cleaning Wand
After soaking, take the filters out of the cleaning solution and rinse them with fresh water.
A filter cleaning wand, which attaches directly to your garden hose, can make the rinsing process quicker and more thorough by reaching deep into the pleats of the filter.
Product Recommendation:
Life Water Wand Cartridge Cleaner Pro
Important note: Do not use a high-pressure hose, pressure washer or stiff brush as these can damage the filter media.
Step 4: Reinstall Filters in Your Spa
After thoroughly rinsing the filters, carefully screw them back into place in the spa’s filter compartment. Be cautious not to cross-thread if they are threaded.
Bonus Tip – Rotate with a Second Set of Filters
If you have an extra set of filters, you can keep one set soaking for a full week while the other is in use. This routine will significantly extend the life of your filters by ensuring a deep clean every week.
Takeaway: Regular spa filter maintenance is essential for filter longevity. Cleaning your spa filter is quick and easy with a filter cleaning wand. Avoid using a high-pressure hose or stiff brush, as these can damage the filters.
What should you use to clean a spa filter?
Soak your filters in a recommended filter cleaning solution, such as Zodiac Filter Cartridge Cleaner, to help remove dirt, grime, and oils.
After soaking, rinse the filters thoroughly using a filter cleaning wand to ensure they are fully clean before placing them back in your spa.
How often should I clean spa filters?
It’s generally recommended to rinse your spa filters every 1-2 weeks. For spas with high usage or many bathers, more frequent cleaning may be necessary.
Besides rinsing every 2 weeks, you should also soak your filters in a filter-cleaning solution at least once a month.
How long do spa filters last?
Typically, spa filters last between 12 to 18 months before needing replacement. In a frequently used spa, filters may need to be replaced more often.
Consistent, thorough cleaning can help extend the lifespan of your filters.
How can I tell when my spa filter needs replacing?
Signs that a spa filter needs replacement include cloudy water, frequent clogging that requires more frequent cleaning, reduced water flow, and high differential pressure (the difference between incoming and outgoing pressure, often due to a clogged cartridge). Additionally, a cracked or damaged cartridge, though uncommon, may also indicate a need for replacement, especially if there are plumbing issues in the spa.
Frequently Asked Questions
Can I use bleach to clean spa filters?
No, bleach is not recommended for cleaning spa filters. It can damage and weaken the filter media, reducing the filter’s lifespan and effectiveness.
Can I use Nappy San to clean my spa filters?
It’s a common misconception that bleach, Nappy San, or similar products are suitable for cleaning spa filters. In reality, these can harm the filter media and shorten its lifespan.
We recommend using a specialized filter cleaning product, which is designed to remove debris effectively without damaging the filter cartridge.
Can I clean my spa filters in the dishwasher?
No, dishwashing powder is highly caustic and can damage the filter fabric or media.
Why is my spa filter brown?
If your filter appears stained (brown, grey, green, or yellow), it may indicate that the filter material has deteriorated and it’s time for a replacement.
If the filter returns to a white color after a thorough soak and rinse, it’s likely fine to keep using it. However, if it remains stained after cleaning, it’s best to replace it.
