In this guide, you’ll learn why cleaning your spa filter matters, how often to do it, the best cleaning methods, and expert tips to help you keep your spa running at its best. Whether you’re a new spa owner or simply looking to improve your maintenance routine, this step-by-step guide will make the process simple and effective.
Why Cleaning Spa Filters Matters
Keeping your spa clean and healthy goes beyond treating the water—it starts with the spa filter. Your filter acts as the first line of defence against dirt, oils, and debris that accumulate in the water. Regularly cleaning your spa filter ensures that your spa system runs efficiently and your water stays crystal clear.
1. Keeps Water Clear and Safe
When your filter is clogged with dirt, it can’t effectively trap new contaminants. This leads to cloudy or murky water that looks unpleasant and can harbour harmful bacteria. By cleaning your spa filter regularly, you maintain clear, sparkling water that’s safe and enjoyable to soak in.
2. Improves Spa Performance
A dirty filter makes your spa pump work harder, which can strain the motor and reduce water flow through the jets. Proper cleaning of your spa filter keeps the system running smoothly and helps maintain strong, even jet pressure. You’ll notice better performance and less wear on your spa components.
3. Extends the Lifespan of Your Spa Equipment
Dirt buildup not only affects water quality but can also damage the spa’s internal parts. When debris circulates back into the system, it can clog pipes or harm the heater and pump. Routine cleaning of the spa filter protects these components, saving you from expensive repairs and extending the overall life of your spa.
4. Reduces Chemical Use
When your filter is doing its job efficiently, you’ll need fewer chemicals to balance and sanitise your water. This not only saves money but also makes the water gentler on your skin and eyes. Regular spa filter cleaning supports a healthier, more natural spa experience.
5. Prevents Odours and Residue
A neglected filter can cause unpleasant smells or leave residue along the waterline. By keeping up with cleaning your spa filter, you eliminate these issues before they start, keeping your spa fresh and inviting every time you use it.
Key Takeaway:
Cleaning your spa filter is one of the simplest yet most important maintenance steps you can take. It helps you enjoy clean, clear, and healthy spa water while protecting your equipment and saving on maintenance costs.
How Often Should You Clean Your Spa Filter?
One of the most common questions spa owners have is how often to clean their spa filter. The truth is — it depends on how frequently you use your spa and the number of people using it. However, a consistent cleaning schedule is essential to keep your water clear and your spa performing efficiently.
Weekly: Quick Rinse
If you use your spa regularly, it’s best to rinse your spa filter once a week.
Simply remove the filter and rinse it thoroughly with a garden hose to remove surface dirt, hair, and oils. Avoid using high-pressure water, which can damage the pleats.
A weekly rinse helps your filter stay free-flowing and prevents dirt from building up between deeper cleans.
Monthly: Deep Cleaning
Once a month, perform a deep cleaning of your spa filter to remove stubborn debris, oils, and mineral buildup.
Soak the filter overnight in a spa filter cleaner or a DIY solution made of one part vinegar to three parts water. After soaking, rinse it thoroughly and let it dry before reinstalling.
This deep clean ensures that the filter media remains effective and extends its lifespan.
Every 3–4 Months: Rotation or Replacement
If your spa gets heavy use, consider keeping two filters. Rotate them every month — while one is in use, the other is being cleaned and dried. This helps your filters last longer and ensures your spa system is never running with a dirty filter.
Most spa filters should be replaced every 12–18 months, depending on usage and maintenance habits.
Signs Your Spa Filter Needs Immediate Cleaning
Even with a schedule, you should clean your spa filter sooner if you notice:
- Cloudy or foamy water
- Weak jet pressure
- Strange odours
- The filter looks visibly grey, greasy, or clogged.
These are clear signs that the filter can’t properly trap contaminants anymore.
Key Takeaway:
For the best results, rinse your spa filter weekly, deep clean it monthly, and replace it at least once a year. Following this routine keeps your spa water crystal clear, your system running smoothly, and extends the lifespan of your filter.r.
Step-by-Step Guide to Cleaning Spa Filter
If you want your spa water to stay clear and your system to run efficiently, cleaning your spa filter properly is key. This step-by-step guide will walk you through the entire process — from removal to reinstallation — so you can maintain your spa filter like a pro.
Step 1: Turn Off the Spa System
Before you start cleaning the spa filter, always switch off the power to your spa. This prevents water from circulating and ensures your safety while handling the equipment.
Step 2: Remove the Spa Filter Carefully
Open your spa’s filter compartment and take out the filter cartridge. Handle it gently to avoid damaging the pleats or plastic frame.
If you’re unsure where your filter is located, check your spa’s user manual for guidance.
Step 3: Rinse the Filter with Water
Use a garden hose to rinse off loose debris, hair, and dirt. Spray between the pleats at a 45-degree angle to remove buildup without tearing the filter material.
Avoid using a high-pressure washer—it can damage the fibers and shorten the filter’s life.
Step 4: Soak the Filter in a Cleaning Solution
For a deeper clean, soak your spa filter in a filter-cleaning solution or a homemade mix (1 part vinegar to 3 parts water). Let it sit for at least 8–12 hours to dissolve oils, minerals, and grime.
If you use a commercial cleaner, follow the product’s label instructions carefully.
Step 5: Rinse Thoroughly and Let It Dry
After soaking, rinse the filter thoroughly with clean water to remove any leftover cleaner. Ensure the filter is fully air-dried before reattaching it.
This step helps kill any remaining bacteria and ensures the filter performs efficiently.
Step 6: Reinstall the Filter and Restart the Spa
Once your filter is fully dry, place it back into the filter compartment, secure the cover, and turn on your spa system.
Check the water flow and jet pressure to make sure everything is working properly.
Pro Tips for Better Results
- Keep two spa filters and rotate them monthly for convenience.
- Rinse your filter weekly, deep clean monthly, and replace yearly.
- Keep harsh chemicals out of your cleaning routine, as they can ruin the filter’s material.
- Use a spa filter cleaning brush to reach between pleats more effectively.
Key Takeaway:
Regularly cleaning your spa filter not only keeps your water clear and healthy but also protects your spa equipment and saves money on repairs. A few minutes of proper maintenance can make all the difference in your spa’s performance and longevity.
Best Cleaning Solutions for Spa Filters
When it comes to cleaning your spa filter, using the right solution can make a big difference. The right cleaner helps remove oils, minerals, and dirt buildup without damaging the filter material. There are two main types of cleaners you can use — DIY natural cleaners and commercial spa filter cleaners.
1. DIY Natural Cleaners
If you prefer gentle and affordable cleaning methods, for example homemade bathroom cleaners are a great choice.
Vinegar Solution
Blend one measure of white vinegar with three measures of warm water.
. Soak the filter for 8–12 hours to dissolve oils, calcium, and grime. Rinse thoroughly afterward.
This natural option is ideal for regular maintenance and light dirt buildup.
Baking Soda Mix

It’s gentle on the filter material and works well between deep cleans.
Best for: Light cleaning, eco-friendly maintenance, and regular upkeep.
Avoid for: Extremely dirty or oily filters — it may not be strong enough for heavy buildup.
2. Commercial Spa Filter Cleaners
For deep cleaning and heavily used spas, commercial filter cleaners are highly effective. They’re specially designed to break down body oils, lotions, and mineral deposits that natural cleaners may not fully remove.
These cleaners are available in two forms:
- Liquid Soak Cleaners: Used by diluting in water and soaking overnight.
- Spray-On Cleaners: Ideal for quick cleaning when you’re short on time.
When using a commercial product, always follow the manufacturer’s instructions carefully and rinse the filter completely before reinstalling.
Best for: Heavy buildup, professional maintenance, and deep cleaning.
Avoid for: Frequent light cleaning, as strong chemicals may wear out the filter over time.
3. What Not to Use
Some products may seem effective but can actually harm your spa filter or your skin.
Avoid:
- Bleach or chlorine-based cleaners – they can weaken the filter fibers.
- Dish soap or detergents – these create foam in the spa water.
- High-pressure washers – they can damage filter pleats.
Key Takeaway:
The best cleaning solution for your spa filter depends on how dirty it is.
- Use vinegar or baking soda for gentle, regular cleaning.
- Use a commercial filter cleaner for deep cleaning or heavily used spas.
No matter which method you choose, cleaning your spa filter regularly keeps your water fresh, your system running smoothly, and your spa experience enjoyable.
Common Mistakes to Avoid When Cleaning Spa Filter
Regularly cleaning your spa filter is essential for keeping your water clear and your system running efficiently. However, even with the best intentions, many spa owners make mistakes that can reduce filter performance or cause damage.
Here are the most common mistakes to avoid when maintaining your spa filter.
1. Using Harsh Chemicals
Bleach, detergent, and chlorine-based cleaners might seem like effective options, but they can actually damage the filter fibers and shorten its lifespan. These chemicals can also leave residues that cause foaming or irritation when you use the spa again.
Tip: Always use a spa filter cleaner or a gentle homemade solution like vinegar and water.
2. Skipping Regular Cleaning
Many people wait until the water turns cloudy before cleaning their spa filter, but by then, the damage may already be done. A dirty filter restricts water flow, strains the pump, and allows bacteria to grow.
Tip: Rinse your filter weekly, deep clean monthly, and replace it every 12–18 months.
3. Using High-Pressure Water
Using a high-pressure washer or nozzle can easily tear the pleats or damage the filter material. While it might look clean, the damage can make the filter less effective at trapping debris.
Tip: Use a garden hose with a gentle stream and spray between pleats at an angle.
4. Not Rinsing After Soaking
After soaking your filter in a cleaning solution, failing to rinse it properly can leave chemical residue behind. These residues can mix with spa water and cause foaming, odor, or irritation.
Tip: Always rinse the filter thoroughly with clean water before putting it back in your spa.
5. Reinstalling a Wet Filter
Reinstalling the filter before it’s completely dry may trap moisture inside, leading to bacteria or mold growth. This can make your spa smell unpleasant and affect water quality.
Tip: Allow your spa filter to air dry completely before reinstalling.
6. Ignoring Filter Replacement
Even with perfect care, spa filters don’t last forever. Over time, the material breaks down and can no longer trap fine particles effectively.
Tip: Replace your filter every 12–18 months, or sooner if you notice reduced performance or discoloration.
Key Takeaway:
Properly cleaning your spa filter means more than just a quick rinse. Avoid harsh chemicals, stick to a regular cleaning routine, and treat your filter gently to extend its life and keep your spa water clean and safe.
Maintenance Tips to Extend Filter Life
Taking good care of your spa filter doesn’t just keep your water clear — it also saves you money in the long run. With a few simple habits and consistent care, you can extend the life of your spa filter and keep your spa running at its best.
1. Stick to a Regular Cleaning Schedule
The easiest way to make your filter last longer is by keeping up with regular cleaning.
- Rinse weekly to remove surface dirt and oils.
- Deep clean monthly using a spa filter cleaner or vinegar soak.
- Replace every 12–18 months, depending on usage.
Consistent cleaning of your spa filter prevents buildup that can strain your spa system and damage the filter material.
2. Rinse After Every Heavy Use
If you’ve had a long soaking session or multiple people used the spa, your filter will have trapped extra dirt and body oils. Giving it a quick rinse right after heavy use helps maintain water quality and prevents clogging.
3. Rotate Between Two Filters
Owning two spa filters and rotating them is a simple trick that can extend your filter’s lifespan. While one is being cleaned and dried, you can use the other. This rotation gives each filter enough time to dry completely, reducing wear and the chance of bacteria growth.
4. Keep the Water Balanced
Unbalanced water — especially with high calcium or pH levels — can cause scale buildup on your filter. This buildup reduces water flow and makes cleaning more difficult.
Check your spa’s water chemistry at least once a week, and adjust sanitizer, pH, and alkalinity levels as needed.
5. Let the Filter Dry Completely
After cleaning your spa filter, always let it dry completely before reinstalling. This prevents mold, mildew, and bacteria from developing inside the pleats. A dry filter also traps debris more efficiently once it’s back in the spa.
6. Inspect for Wear and Tear
Even with regular maintenance, filters eventually wear out. Look for:
- Cracks in the plastic frame
- Frayed or torn pleats
- Stains that don’t wash off
If you notice any of these, it’s time for a replacement. Using a damaged filter can allow dirt and oils to circulate back into your water.
Key Takeaway:
Regular cleaning of your spa filter, rotating between two filters, and maintaining proper water balance are the best ways to extend your filter’s life. These small steps help you save money, protect your spa equipment, and enjoy clean, clear water every time you relax.
