More information on hot tub filters
Effective bath water cleaning with Sannra spa filter
Traditional hot tub filters consist of filter material that is folded (pleated) around the filter. The material is pleated around the filter to allow a larger area of material to fit around the filter. The tighter the pleats, the larger the surface area of the filter.
The material of our Sannra filters for hot tubs is made of Trilobal polyester fibre. The three-sided Trilobal shape makes the filter significantly more efficient than filters with traditional fibres, as the effective surface area of the filter is increased by the three-sided shape. The shape itself also makes the material more effective in absorbing particles.
Cleaning of spa filters
To maintain the efficiency of the filter, it needs to be cleaned, otherwise it becomes clogged and stops the flow in the bath. If less water is circulating, it will not be cleaned as effectively. The Trilobala fibres in the filter material of our Sannra spa filters allow dirt to be released more easily during cleaning.
Clean and rinse your spa filter at least every 14 days. The filters are cleaned by rinsing them with water. At regular intervals, also clean them with Filter Cleaner which dissolves grease and other contaminants without damaging the filter media or solder.

We recommend having two sets of filters for easy and efficient management.
Even if you clean your spa filters, some dirt remains in them, it builds up over time and clogs the filters. This is why you need to change them regularly. How often you need to change them depends on how well you take care of the filters. A good rule of thumb is to change filters every 12 months.
