Which filter is the right one for your whirlpool tub?

How do you find the ideal filter for your hot tub?

A hot tub in the garden is a real oasis of well-being - perfect for relaxation and recreation. However, to ensure that the water always remains clear and clean, a functioning filter system is essential. But which filter is best suited to your hot tub? This guide will provide you with comprehensive guidance and help you choose the ideal filter.

Why is a filter system so important?

The filter system ensures that your hot tub water remains hygienic and free of dirt particles. A circulation pump draws in the water, passes it through the filter and returns it - optionally heated - to the pool. Dirt and residues are trapped in the filter.

A clean filter is not only essential for your bathing pleasure, but also for the longevity of your whirlpool.


The different types of hot tub filters

Most whirlpools are equipped as standard with a lamella filter as standard. These filters consist of a fine-pored plastic fleece that offers a particularly large cleaning surface thanks to its star-shaped pleating. In addition to lamella filters, there are also other filter types that can be considered depending on requirements:

  • Cartridge filtersEasy to use and relatively inexpensive. They need to be cleaned regularly and replaced depending on the degree of soiling.

  • Sand filtersThese systems offer high efficiency and longevity, but require more installation work.

Which filter is best for your hot tub depends on the size of the pool, the intensity of use and your personal preferences. Seek advice from a specialist dealer to find the right filter.


How to look after your filter properly

A well-maintained filter is the be-all and end-all for clean whirlpool water. Follow these basic rules:

  1. Regular cleaningClean the filter at least once a week by spraying it with a garden hose or using special cleaning systems.

  2. Gentle wash cycleSome filters can be cleaned in the gentle cycle of the washing machine. Ask your specialist dealer whether this also applies to your filter.

  3. Regular replacementEven with good care, filters wear out over time. Replace your Whirlpool filter every six months or so to ensure optimum performance.
