Why It’s Important To Change Your Spa Filter

Before we jump into spotting a worn-out or bad spa filter, let’s go over why it’s important to change the filter regularly – this goes for hot tubs too! A filter plays a huge role in keeping your spa or hot tub free from dust, debris, dirt, and other unwanted particles that could ruin your water experience. Additionally, regular changes help keep the water clean and clear, allowing you to relax and enjoy your time in your spa or hot tub without any worries.

Signs It’s Time to Change Your Spa or Hot Tub Filter

Sign 1: The Water Looks Dirty

One of the easiest ways to tell if your spa or hot tub filter needs replacing is glancing at its water. How does it look? If it doesn’t look clean and clear, and instead appears dull and dirty, this might be a sign that it’s time for a replacement filter.

Sign 2: The Filter is Worn-Out and Discolored

Check your spa’s or hot tub’s filtration system. A bad filter will appear worn-out with rips, or simply look dirty with an off-putting color – usually green, brown, or yellow. This condition and discoloration lead to poor water circulation, making its purpose of cleaning your spa or hot tub water almost useless.

Sign 3: Algae Growth in Your Spa or Hot Tub Water

Since a bad filter doesn’t help much anymore when it comes to cleaning your spa or hot tub water, it leaves the water vulnerable to algae growth. Algae growth can be caused by a few things, and bad filtration is just one of them due to the poor water circulation it creates.

Sign 4: Strange Noises Coming From The Pump

If your spa or hot tub filter gets bad or clogged, your pump might start making louder or unusual sounds. If you notice this happening, it’s probably time to get a new filter. Once you put in a new filter, the sound should go away.

What Happens If I Don’t Change My Spa or Hot Tub Filter?

The longer you neglect your spa’s or hot tub’s filtration system, the more dirty, unpleasant, and unsafe the water will become for you to enjoy. The filter starts to become less effective and you will notice dirt, dust, debris, and other small particles lurking in the water. In some cases, the failure to replace your filter regularly can even cause damage to other parts of your spa like the pump.

Other Frequently Asked Questions

How long should a spa filter last?

Most hot tub and spa filters need to be replaced once a year. However, some high-quality filters can last longer and it depends on how often you use your hot tub or spa. Low-quality filters, on the other hand, may need to be replaced much sooner. Check your filter’s packaging to see how long yours will last.

How do you clean a spa filter?

After removing our filter from your hot tub or spa, gently rinse it under cool water. Then, slowly pull the pleats apart by using your fingers to allow more water to rinse in-between them. Doing this helps keep your filter clean while also checking for any signs of damage.

How do you maintain a clean spa filter?

To maintain a clean spa filter, you can rinse it under cool water weekly, soak it in a filter cleaner for 10 minutes each month for a deeper clean, or immerse it in a diluted filter cleaner for 12 to 24 hours every three months.

Should I leave my spa filter on all the time?

To keep your spa’s water circulated, filtered, sanitized, and kept at its ideal temperature, it is recommended to keep your spa filter running. Spas are designed to filter and heat when not in use, turning the filtration system off could cause the water to become dirty and unsafe to enjoy.
