Compare your filter with the images and choose. This filter is for spas with 3 filters, combined with 2 x No.1. Filter No. 2 is a Purezone micro-membrane filter that filters even very small particles. Due to the fine membrane, the filter does not last as long as a standard filter, and is especially sensitive to fats such as sunscreen, skin care articles and other fatty substances. If you experience problems with rapid blockage, the filter may be replaced by Filter No.1. Filter No. 2 cannot be cleaned with filter cleaner.
