The Best Way to Clean Spa Filters for a Fresh and Healthy Soak

Owning a spa is all about relaxation and luxury, but to keep your water crystal clear and safe, your spa filter needs regular attention. The filter plays a crucial role in trapping dirt, debris, and oils, preventing them from circulating back into the water. A clean filter means not only cleaner water but also a longer lifespan for your spa equipment. Here is the best way to clean spa filters and keep your soak as fresh as the day you bought it.

Step 1: Turn Off and Remove the Filter

Before starting, make sure the spa is turned off at the power supply. This is important to avoid any electrical hazards and to ensure the filtration system does not operate while you are working. Locate the filter housing and carefully remove the filter cartridge. Depending on your spa, it may twist out, lift out, or require unscrewing a cap. Take note of how it sits in the housing so you can easily reinstall it later.

Step 2: Rinse with Fresh Water

The first stage of cleaning is to remove loose debris like leaves, hair, and dirt. Using a garden hose, rinse the filter from top to bottom. Aim the water between the pleats to flush out trapped particles. Avoid using high pressure settings or pressure washers, as this can damage the pleats and shorten the life of the filter. A gentle but thorough rinse is enough to clear the first layer of grime.

Step 3: Use a Filter Cleaning Solution

For a deeper clean, soak your filter in a spa-specific cleaning solution. These are designed to break down body oils, sunscreen residue, and other contaminants that water alone cannot remove. Fill a clean bucket or large tub with the recommended amount of water and add the cleaning solution according to the manufacturer’s instructions. Place the filter inside and allow it to soak for at least 12 hours, or overnight, to ensure all contaminants are dissolved.

Step 4: Rinse Again and Dry

After soaking, give the filter a second rinse with the garden hose to remove any remaining cleaning solution and loosened debris. Shake off excess water and allow the filter to dry completely before putting it back in the spa. Drying helps kill any remaining bacteria and prevents mould growth. If you have a spare filter, this is the perfect time to swap them, so one is always clean and ready for use.

Step 5: Check for Damage

While cleaning, inspect the filter for any tears, cracks, or worn areas in the pleats or end caps. A damaged filter will not perform effectively and can allow dirt and contaminants to pass through. If you notice damage or the pleats are too worn, it is time to replace the filter. Most spa filters need replacing every 12 to 18 months, depending on usage and maintenance.

Extra Tips for Maintaining Spa Filters

• Rinse the filter with fresh water every 1 to 2 weeks, depending on how often you use the spa.

• Perform a deep clean with a soaking solution every month.

• Avoid using household cleaners or detergents, as these can leave residues that foam up in your spa water.

• Keep a spare filter on hand so you can rotate them and extend their lifespan.

• Maintain balanced water chemistry, as unbalanced water can cause scale or oil buildup that clogs filters more quickly.

Why Regular Filter Cleaning Matters

A clean spa filter improves water circulation, helps the heater work more efficiently, and ensures sanitising chemicals perform at their best. Neglecting your filter can lead to cloudy water, unpleasant odours, and even damage to your spa pump. By sticking to a consistent cleaning routine, you will protect your investment and enjoy a better spa experience.

Regular filter care is a simple yet vital task for every spa owner. With the right tools, a gentle hand, and a little patience, your filter will keep your water sparkling and your spa ready for relaxation at any time.
