Cleaning Hot Tub Filters – Your Complete Filter Care Routine

Maintaining a hot tub is more than keeping the water warm; it’s about ensuring every soak is a clean, refreshing experience. Central to this goal is cleaning hot tub filters, a component crucial to your hot tub’s health and efficiency.

A clean filter not only guarantees crystal-clear water but also protects the inner workings of your hot tub from damage due to contaminants.

Let’s explore how you can keep your hot tub filters in top condition, ensuring they last longer and your hot tub remains a sanctuary of relaxation.

The Role of Filters in Hot Tub Health

Hot tub filters play the pivotal role of guardians in the realm of your hot tub’s ecosystem. By trapping debris, hair, and other particulates, they ensure your water remains inviting and safe.

However, when filters become clogged, the entire system strains to circulate and heat water, leading to cloudy conditions and potential damage to the hot tub’s pump and heating systems.

Understanding the importance of routinely cleaning hot tub filters underscores the need for diligent maintenance.

Cleaning Hot Tub Filters: Routine Maintenance

Adopting a structured approach to filter maintenance is akin to setting a foundation for your hot tub’s enduring performance. It revolves around a simple yet effective regimen: weekly rinses, monthly cleans, and quarterly deep cleans.

This trio of care ensures your filters remain in prime condition, ready to tackle anything your hot tub sessions throw their way.

Weekly Rinse: Keeping Filters Debris-Free

Initiate your filter care with a weekly rinse; a straightforward yet effective first line of defence against debris accumulation. Here’s how you can quickly clean your filters each week:

  • Rinse thoroughly: Use a garden hose to gently wash away loose debris from the filter’s pleats. Avoid using high pressure, which can damage the filter media.
  • Inspect regularly: After rinsing, take a moment to inspect your filter for any signs of wear or damage. Early detection can prevent bigger issues down the road. Discolouration, stains, tears or holes, are all indications that it is time to replace the filter.

To make this cleaning even more effective, consider getting a filter flosser—a hose attachment specifically designed to clean between the pleats of tub filters.

Monthly Clean: Deep Cleaning without the Soak

For a monthly clean, introducing a spray-on, rinse-off filter cleaner makes the task even more effective. This process helps penetrate the material of the pleats, breaking down stubborn oils and grime. Here’s your guide:

  • Rinse and inspect: Following the same steps as your weekly routine, thoroughly rinse off your filters and check for any damage.
  • Spray liberally: Apply your chosen filter cleaner across all pleats, ensuring even coverage. These cleaners are designed to penetrate and dissolve oils and scale without the need for soaking.
  • Wait, then rinse: After waiting for the time recommended by the cleaner’s instructions, typically 5 minutes, thoroughly rinse the filter to wash away the dissolved contaminants.

Regular monthly cleaning with a spray-on cleaner is your maintenance middle ground, balancing convenience with thoroughness.

Quarterly Deep Clean: The Soak Method

Every three or four months, it’s time for a deep clean that rejuvenates your filter from the inside out. This soak is crucial for eliminating deeply embedded dirt, oils, and scale that regular rinsing can’t reach.

We recommend deep cleaning your filter when you do your hot tub drain and fill (every three or four months, depending on use).

  • Rinse and inspect: After removing your filters, rinse as usual and perform an inspection to ensure there are no indications that a new filter is required.
  • Prepare your soak: Choose a quality filter cleaning solution, such as Jacuzzi®️ Cartridge Cleaner, and prepare a soak according to the product directions. Ensure the filter is fully submerged for the duration recommended.
  • Soak, then rinse: After soaking, rinse the filter thoroughly to remove all traces of the cleaning solution. This step is vital to prevent foaming or chemical imbalances in your hot tub.

Recognizing When Replacement is Necessary

No matter how meticulous you are with cleaning, every hot tub filter reaches a point where it can no longer perform its essential functions effectively.

It’s crucial to acknowledge that filters are consumable items designed with a finite lifespan intended to safeguard your hot tub’s cleanliness and operational integrity.

Recognizing the right time to replace your filter is pivotal for maintaining the optimal performance of your hot tub and ensuring the water remains clean and safe for users.

1. Signs of Wear and Tear

The first indicator that your filter might need replacing is visible wear and tear. Fraying of the filter fabric is a clear sign that the material is degrading, which can significantly diminish its ability to trap and hold debris.

Similarly, any tears or cracks in the filter material can cause damage to your hot tub, allowing particles to bypass the filter and circulate back into the spa – or worse get caught in the pump impeller, wrapped around your flow switch, or stuck in your heater!

2. Persistent Bad Odor

Another red flag is a persistent bad odour emanating from the filter, even after a thorough cleaning.

This unpleasant smell can be a sign that bacteria or mold has deeply embedded itself in the filter material, beyond the reach of standard cleaning methods.

Not only does this affect the water quality, but it can also become a health concern for hot tub users.

3. Loss of Cleaning Efficiency

Over time, you might notice that cleaning the filter no longer restores its functionality to an acceptable level.

This decrease in efficiency can manifest as dull, murky, or cloudy water, increased foam production, or the necessity for more frequent chemical adjustments to maintain water balance. These symptoms suggest that the filter is no longer capable of keeping the water clean.

4. Flow Errors

Old filters can increase the strain on the filtration system, and even slow down the water flow to trigger an “open flow” switch error (often presented as error code FL1, FLO or DRY).

If you are getting intermittent or persistent flow errors, your filter may need to be cleaned or replaced. If, after cleaning your filter, it soon triggers another flow error, you probably need to replace the filter.

A Timely Replacement

Addressing the need for a filter replacement in a timely manner is essential to avoid water quality issues that can tarnish the hot tub experience.

Moreover, it’s about protecting the hardware of your hot tub. Using a worn-out filter can lead to more significant, costly repairs down the line, as the hot tub works harder to circulate and heat water through a compromised filtration system.

Being vigilant about the condition of your hot tub filter and recognizing when it’s time for a replacement are key aspects of responsible hot tub ownership.

Regular inspections and acknowledging the signs of wear and diminished functionality will ensure your hot tub remains a safe, enjoyable retreat for years to come.

Remember, a clean, well-maintained filter is the backbone of a healthy hot tub environment, protecting both the users and the investment in your hot tub.
