How Often to Change Hot Tub Filters (And Why It Matters)

spa filter maintenance

There are a few elements of hot tub maintenance that are vital to maintaining safe, healthy operations, and spa filter maintenance is always high on this list. How often do you need to change your hot tub filters, and which risks are present if you do not stick to this general schedule?

At Hot Tub Factory Outlet, we offer the top selection of hot tubs available around Salt Lake City, plus tips and expertise on how to properly care for all our products - including spa filter maintenance. Here are some basics on how often hot tub filters should be changed, including the risks you're taking if you don't change them regularly.

General Spa Filter Replacement Timeline

While this can vary significantly based on some factors we'll discuss in a bit, the general rule of thumb is that you should plan on replacing your hot tub filter every 12-24 months. This is the timeline recommended by most manufacturers, and it allows for proper filtration and water quality maintenance over time.

Risks of Dirty Spa Filters

There are several risks that are present if filters are not changed often enough:

  • Cloudy water: As the filter becomes clogged with dirt, it becomes less effective at filtering out impurities and contaminants. This can result in cloudy or murky water and decreased water quality.
  • Poor circulation: A dirty filter can also restrict water flow, which can impact the overall circulation of your hot tub. This can lead to stagnant areas in the water where bacteria and algae can grow.
  • Damage to other components: When a filter is not functioning properly, it puts added strain on other parts of your hot tub, such as the pump and heater. Over time, this can lead to costly repairs or replacements.
  • Bacteria buildup and health concerns: As mentioned earlier, a dirty filter can harbor bacteria and other contaminants. This can pose a health risk to those using the hot tub, especially if they have open cuts or sores.
  • Reduced energy efficiency: A clogged or dirty filter can also lead to decreased energy efficiency in your hot tub. When the water is not being properly filtered, it requires more energy to heat and maintain a clean temperature.

Signs Your Filter Needs to Be Cleaned or Replaced

Here are a few signs your spa filter may need to be changed, possibly more often than the recommended frequency:

  • Noticeably dirty water: If you can see debris floating in the water, it's a clear sign that your filter is not working properly.
  • Strong chemical smell: A clogged or dirty filter can cause chemicals to build up in your hot tub, resulting in a strong odor. This is not only unpleasant, but it can also be dangerous for those using the spa.
  • Difficulty balancing chemicals: If you're having trouble keeping your hot tub's chemical levels balanced, it could be due to a clogged filter. The buildup of debris and contaminants can make it harder for chemicals to effectively do their job.

How Proper Filter Care Extends Equipment Lifespan

It's not just your filter itself that benefits from regular spa filter maintenance. By ensuring your filter is clean and functioning properly, you can also extend the lifespan of other components in your hot tub:

  • Pump: A clogged or dirty filter can put extra strain on your hot tub's pump, causing it to work harder and potentially leading to costly repairs or replacement.
  • Heater: Similarly, a dirty filter can restrict water flow and put more strain on your heater, reducing its efficiency and potentially shortening its lifespan.
  • Jets: Clogged filters can also affect the performance and effectiveness of your jets. If they aren't getting enough water flow due to a dirty filter, they won't be able to provide the desired massage experience.

Importance of Periodic Deep Cleaning

In addition to regular spa filter cleaning, it is also important to periodically deep-clean your hot tub. This involves draining the water, scrubbing the surfaces of the tub, and sanitizing it with specific spa cleaning products.

Deep cleaning can help remove any built-up residue or contaminants that may not have been caught by regular filter maintenance. It can also help prevent hard water buildup and extend the longevity of your hot tub components. Moreover, a deep cleaning session allows for close inspection of all parts of your hot tub, ensuring that any potential issues are identified and addressed before they become costly problems.
