How to Change and Clean Hot Tub Filters

Many people in Tucson have a hot tub, and they love the hot tub experience - relieving stress, spending time with friends and family, and taking time to relax. 

If you have a hot tub, though, you need to keep the water safe and clean, and the best way to do that is to ensure the filter is working correctly. The filter helps to keep hot tub water clean by trapping dirt, debris, and other contaminants so that it doesn't collect in the water. 

Over time, however, the filter will become clogged. When this happens, the water in your hot tub will get cloudy, it might begin to smell, and it will put more strain on your pumps, heaters, and other parts. 

Fortunately, learning how to clean your filter and then change it when necessary is generally pretty simple. With regular maintenance and occasional professional service, you can keep your hot tub or swim spa working well throughout the year. Learning how to drain and refill your hot tub can also be helpful.

• Ceramic filters - These are long-lasting and very durable, but aren't often used in residential hot tubs.

If you follow the instructions to change your hot tub's filter, it's really an easy job. Hot tub cleaning services may be able to help with this. Here's the step-by-step process to keep the water clean and improve the life of your filter:

Step 1 – Turn Off the Power

The most important thing during the cleaning of your hot tub filter is to make sure the power is off. This is a safety step that will turn the pump off and keep you safe when handing electrical equipment. 

Step 2 – Remove the Filter

Find the filter compartment and remove the dirty filter. You can simply remove the filter but be careful not to smash the pleats, as this will reduce it's effectiveness. 

Step 3 – Rinse the Filter

Use a garden hose to rinse the filter cartridge, making sure you get between the pleats. Don't use any full power sprayer, as it can put a hole in the filter, which will reduce water quality and cleanliness.

Step 4 – Soak the Filter in Hot Tub Filter Cleaner

If you want a deeper clean, you can use a filter cleaner or make your own with vinegar and baking soda. Allow the filter to soak overnight for best results. 

Step 5 – Rinse Again and Dry

After you soak the filter, rinse it again, and then make sure to dry completely before reinstalling it in the hot tub. Check the filter pleats one more time before you put it back in your spa or hot tub. If you damage the filter, it is time to replace it with a second filter. 

How to Replace Your Filter - Filter Replacement 

Even with regular cleaning, filters eventually lose efficiency. Over time, the fabric wears down, the pleats flatten, and the filter simply can’t trap particles like it used to.

Most manufacturers recommend replacing cartridge filters every 12–24 months, depending on usage. If your hot tub is used daily or by multiple people, replacement may be needed sooner.

Steps to replace a hot tub filter:

1. Turn off the hot tub power. Safety first.

2. Remove the old filter. Follow the same process as cleaning.

3. Clean the filter housing. Wipe away any grime or buildup inside the compartment.

4. Insert the new filter. Make sure it’s the correct size and type for your spa model.

5. Restart the hot tub. Turn the power back on and run a short cycle to check water flow.

Why replacement matters

While cleaning can extend a filter’s life, eventually replacing it ensures your hot tub runs at peak performance. Fresh filters reduce strain on the pump, improve water clarity, and help keep chemical levels stable.
