Washable spa filters vs. no-clean spa filters - what's the difference?

Spa filters play a crucial role in keeping your spa water clean and fresh. There are two main types of spa filters to choose from: washable lamella filters and cleanable spa filters. Both have their own advantages and are suitable for different types of spa use. Here we explain the differences to help you choose the best filter for your spa.

Washable lamella filters

Washable lamella filters consist of pleated filter material, often made of polyester Trilobal fibre, which effectively removes particles from the water. The pleated layers allow the filter to have a larger surface area to trap contaminants such as skin, hair and make-up.

Advantages of washable lamella filters:

• Sustainability: Can be used for up to 12 months with proper care.
• Cost-effective: A long-lasting solution that can be washed and reused.
• Effective filtering: Removes particles down to 20 microns, which is sufficient for most spas.

Maintenance: Wash the filter every 14 days day with a cleaning agent specially adapted for spa filters. We recommend having two sets of filters to be able to switch easily while cleaning one filter.

Cleaning-free spa filters

Cleaning-free spa filters are designed to simplify maintenance. Made from multiple layers of spun plastic (polypropylene), these filters never need to be washed. You simply replace the filter every three months, saving time and eliminating the need for filter chemicals.

Advantages of cleaning-free filters:

• Time efficiently: Requires no washing or maintenance - just replace the filter after three months.
• More efficient filtering: Removes particles down to 1-5 microns, providing even cleaner water compared to traditional disc filters.
• Convenient: Ideal for those who want to minimise maintenance and care.

Maintenance: Change the filter every three months or more often if the spa is used frequently. Never use flocculants or oil-based products with these filters.

Which filter is best for you?

If you want a filter with minimum effort and maximum performance, the cleaning-free spa filters are an excellent choice. For those who want a more cost-effective solution and are prepared to maintain the filter regularly, the washable lamella filters are the best choice.
