Why it’s important to replace your hot tub filter on time

A properly functioning filter system is the heart of your hot tub .
The filter traps dirt, grease, hair, and other small particles daily, keeping the water clear and hygienic. In this blog post, you’ll learn why it’s so important to replace your filter on time and what can happen if you don’t.

🧴 What exactly does a hot tub filter do?

The filter:

• removes dirt particles and organic material from the water
• helps keep pH and chlorine levels stable
• prevents dirt from settling in the pipes and pump

Without a clean filter, you’ll need to use a lot more pH+, pH-, and chlorine granules to keep the water clear — and even then, it often remains cloudy.

⚠️ Consequences of an old or dirty filter

clogged and less permeable over time .
If you don’t replace it in time:

• the water becomes cloudy and unhygienic
• the pump can become overloaded (shorter life)
• become unbalanced more quickly
• biofilm and bacterial growth develop in the pipes

This means that you will have to correct more often with pH+/pH- and chlorine granules and the risk of skin and eye irritation increases.

🗓️ How often should you replace the filter?

• Rinse the filter thoroughly with clean water 1–2 times a week
• Clean it once a month with a special filter cleaner
• Replace the filter completely every 3 to 6 months (depending on use)

💡 Tip: Combine this with a weekly treatment with AquaFinesse or AquaPerfect to prevent biofilm and limescale deposits.

✅ Benefits of replacing on time

By replacing your filter on time:

• the water remains clear and clean
• pH+ / pH- and chlorine granules work more effectively
• prevent pump and heating malfunctions
• extend the lifespan of your jacuzzi

In short: a new filter is a small effort that prevents many problems.
