Filtration is an essential part of maintaining a clean and hygienic spa. The heat and moisture in a spa pool are a natural breeding ground for bacteria, and outdoor or semi-enclosed environments can let in a lot of dirt and biological debris. Replacing your spa filter cartridges regularly will help keep the filtration system functioning at its best.

There are a large number of different filters available and we understand that selecting the right one can sometimes be confusing. We’re happy to help you make the right selection. We've created a resource article that explains how to measure and identify your current filters so you can order the correct replacement filters.

How often do I need to replace my spa filters?

The frequency of spa filter replacement depends on several factors, including the size of your spa, the number of users, the water quality, and the maintenance routine. However, as a general guideline, it is recommended to replace spa filters every 6 to 12 months. It is essential to regularly clean and maintain the filters in between replacements to ensure optimal performance and water clarity.

How do I know which are the right filters for my spa?

To determine the right filters for your spa, you can follow these steps:

1. Check the spa pool's documentation: Consult the owner's manual or any other documentation provided by the manufacturer. These materials often include information about the specific filter model and size recommended for your spa.

2. Look for filter labels: Many filters have labels or markings that indicate the model number, dimensions, and other specifications. Check your existing filter for any such labels, and note down the information.

3. Measure the existing filter: If your filter doesn't have clear markings, you can measure its diameter and length. Use a measuring tape to determine the exact dimensions. Note down the measurements in inches or millimetres. View the detailed guide on how to measure and identify your spa filters.

4. Consult the manufacturer: Visit the manufacturer's website or contact their customer service directly. Provide them with the model and/or dimensions of your existing filter, or ask for guidance on selecting the appropriate filter for your spa pool. They can assist you in identifying the correct filter based on your specific requirements.

Should I keep a spare set of spa filters? 

Keeping a spare set of filters for your spa can be beneficial. Here are a few reasons why it can be a good idea:

1. Convenience: Having a spare set of filters allows you to easily replace dirty or clogged filters without having to wait for them to dry or go through the cleaning process immediately. You can simply swap out the dirty filters with the clean ones and continue enjoying your spa.

2. Extended Lifespan: By rotating between two sets of filters, you can prolong the lifespan of each filter. Allowing the filters to dry thoroughly between uses helps prevent the growth of mold, mildew, or bacterial buildup. This can help to maintain the effectiveness and performance of the filters over time.

3. Continuity of Use: If a filter becomes damaged or needs to be replaced unexpectedly, having a spare set on hand ensures that you can continue using your spa without interruption. It saves you the hassle of finding and ordering replacement filters when you may want to use your spa immediately.

How do I store spa filters when not in use?

When storing spa filters when not in use, follow these steps to keep them in good condition:

1. Clean the filter thoroughly: Before storing, make sure to clean the filter properly. Rinse it with a hose to remove any loose debris, then soak it in a filter cleaner solution. For a deep clean, soak for 24 hours. Rinse it thoroughly again to remove the cleaner.

2. Allow the filter to dry: It is crucial to let the filter completely dry before storing it. A wet or damp filter can lead to mould, mildew, or bacterial growth. Place the filter in a well-ventilated area and let it air dry completely.

3. Protect the filter: Once the filter is dry, it's a good idea to protect it from dust and debris during storage. You can use a clean plastic bag or a filter-specific storage bag to contain the filter. Make sure the bag is clean and dry before placing the filter inside.

4. Choose a clean storage location: Find a clean and dry place to store the filters. Avoid areas with high humidity or extreme temperatures that can harm the filter material. Additionally, keep the filters away from chemicals or other potentially damaging substances.

How do I clean spa filters?

1. Turn off the spa: Before cleaning the filters, turn off the spa and ensure the circulation pump is not running. This will prevent debris from being sucked into your plumbing while the filters are not in place.

2. Remove the filters: Carefully remove the spa filters from their housing or filter compartment. Refer to your spa's user manual for specific instructions on how to do this.

3. Rinse off loose debris: Use a garden hose with a spray nozzle attachment to rinse off loose debris from the filters. Hold the hose at an angle to ensure the water effectively removes dirt and debris stuck between the pleats.

4. Soak the filters: Fill a clean bucket or container with a filter cleaner solution. Follow the manufacturer's instructions regarding the appropriate amount of cleaner and the recommended soaking time. Place the filters in the solution and make sure they are fully submerged.

5. Agitate the filters: Gently agitate the filters in the solution to help dislodge and remove trapped contaminants. You can use a soft brush or your hand to lightly scrub the filters, focusing on the pleats and other areas where debris tends to accumulate.

6. Rinse thoroughly: After the recommended soaking time, remove the filters from the cleaning solution and thoroughly rinse them with clean water. Ensure that all traces of the cleaning solution are removed. 

Pro Tip: Use a filter cleaning wand to rinse your filters more thoroughly

7. Inspect and dry the filters: Inspect the filters for any signs of damage or degradation. If any parts are worn or damaged, consider replacing them. Afterwards, let the filters air dry completely in a well-ventilated area.

8. Reinstall the filters: Once the filters are completely dry, carefully reinstall them in the spa according to the manufacturer's instructions. Make sure they are properly seated and secured in their housing or filter compartment.

Regularly cleaning your spa filters, usually at least once a month, will help maintain their efficiency and prolong their lifespan. Additionally, following the manufacturer's recommendations and guidelines specific to your spa model is essential for proper maintenance.

Should I keep my spa filtration running all the time?

It is generally recommended to keep the spa filtration running for a certain period of time each day. By running the filtration system continuously or for a set number of hours per day, you ensure that the water is constantly circulated and filtered, removing debris, contaminants, and ensuring water clarity.

The specific recommended filtration time can vary depending on factors such as the size of your spa, the number of users, and the water quality. However, a typical guideline is to run the filtration system for 8 to 12 hours per day. If you use your spa more frequently or have many users, you may need to increase the filtration time.

It's important to consult your spa's user manual or contact the manufacturer for specific guidance on the recommended filtration cycle for your particular model.

Can I use bleach to clean my spa filters?

No, it is not recommended to use bleach to clean spa filters. Bleach can be too harsh and may damage the filter material or reduce its effectiveness. Instead, it is best to use a filter cleaner specifically designed for spa filters. These cleaners are formulated to effectively remove oils, debris, and other contaminants without harming the filter material. Follow the manufacturer's instructions for the proper use and frequency of filter cleaning.

What chemical do I use to clean my spa pool filters?

You can use a dedicated filter cleaner solution that is specifically formulated to remove oils, debris, and contaminants from the filter media. Follow the instructions on the filter cleaning product for proper usage and dilution.

What is the difference between a spa and a pool filter?

Spa and pool filters serve the same fundamental purpose of removing debris, dirt, and other contaminants from the water to keep it clean and safe for users. However, there are some differences between spa filters and pool filters due to the varying requirements of these two types of water systems.

• Size and Capacity:
  • Spa Filter: Spa filters are generally smaller in size compared to pool filters. Since spas have much smaller water volumes, their filters need to be designed to handle lower flow rates and smaller debris loads.
  • Pool Filter: Pool filters are larger and have a higher capacity to accommodate the larger water volume of a swimming pool.
• Filtration Medium:
  • Spa Filter: Spa filters typically use finer filtration media, such as filter paper, that can capture smaller particles. 
  • Pool Filter: Pool filters can use different types of filtration media, including sand, diatomaceous earth (DE), and filtration media in a cartridge form. While sand filters are less efficient at capturing fine particles compared to DE and cartridge filters, they are suitable for larger pool volumes.
• Maintenance Frequency:
  • Spa Filter: Due to the smaller water volume and finer filtration, spa filters may require more frequent cleaning and maintenance to ensure optimal water quality.
  • Pool Filter: Pool filters generally require less frequent maintenance compared to spa filters, but the frequency can vary based on factors like the filter type, pool usage, and environmental conditions.
• Flow Rate:
  • Spa Filter: Spa filters are designed for lower flow rates to ensure proper filtration without putting excess strain on the spa's circulation system.
  • Pool Filter: Pool filters are designed to handle higher flow rates due to the larger water volume in pools.

Where do I find the filters in my spa pool?

The location of the filters in a spa pool can vary depending on the specific model and design. However, in most modern spa pools, the filters can be found within a skimmer or filter housing chamber in the side of the spa body. Here are some common places where you might find the filters:

1. Skimmer: Some spa pools have a skimmer that collects debris from the water's surface. The filters could be located inside the skimmer basket or cartridge within the skimmer assembly.

2. Filter compartment: Many spa pools have a dedicated compartment or chamber for housing the filters. This compartment is usually located near the water pump and can be accessed by removing a cover or lid.

3. Filter housing: In some models, the filters might be directly installed within a housing unit. This housing is typically connected to the plumbing system and can be accessed by unscrewing or detaching it from the spa.

4. Underwater cabinet: Certain spa pools have filters located within an underwater cabinet. These cabinets are usually accessible by removing a panel or door on the side of the spa.

Are spa filters universal?

No, Spa filters are not universal. The size, shape, and specifications of spa filters can vary significantly depending on the manufacturer, model, and type of spa pool. It is important to select the correct filter that is specifically designed for your particular spa pool to ensure effective filtration and optimal performance.

Using the wrong filter may not fit properly or provide adequate filtration, potentially compromising the quality of your spa water.
