Spa filters for Cal Spas, Maax, Viking Spa and others.

Sannra™ Cleaning-free spa filters = No cleaning - No filter chemicals - Clearer bathing water.

No cleaning: You never have to wash dirty filters or buy filter chemicals again. After 3 months, simply replace the filter and insert a new one. Each filter lasts about 3 months of normal bathing. So if you have two filters in your bath, you change them after about 5-6 months.

The filters are made of spun plastic (polypropylene) treated to be antibacterial. The manufacturing process can be likened to making cotton candy where thin strands are formed layer by layer. All these layers give the filter a very large "surface area" that can absorb dirt. The same type of material is used as a filter layer in face masks. Because the plastic in our filters is treated to be antibacterial, it stays fresher for longer.

No filter chemicals: Since the filter does not need to be cleaned, there is no need to buy chemicals to clean the filter.

You will have clearer bathing water with cleaning-free spa filters, as these remove particles down to 1-5 microns. A traditional lamella filter cannot remove particles smaller than about 20 microns. Therefore, if you want equally clear bathing water with lamella filters, you must add flocculants to the bathing water.

Care instructions Cleaning-free Spafilter:

Should be changed every three months for normal bathing. The filters are made of polypropylene, which is a recyclable plastic. Check with your environmental centre what you should sort the filter as.

- If you bathe often and frequently, the filter needs to be changed more often.

If you use two filters, change them every 6 months, etc. If you use several filters in your bath, it is good to check whether the water to the circulation pump goes through one or all filters. If the water goes through a filter, it is good to change the location of the filters occasionally to get an even load on them.

Never use flocculants with these filters. The filters naturally remove small particles that cause cloudy water. Never use oil-based fragrances that clog any type of filter.

We recommend:

After changing the water and cleaning the pipes, use an old rinsed filter for 24 hours. As a rule, there are small particles in the new water and biofilm residues may be released from the cleaning process, shortening the life of the filters.

If you have a very high iron content in the water, which is not filtered out before filling the spa, we advise against using cleaning-free filters as these remove less particles than lamella filters. This causes them to become clogged by the iron particles.
