How to find the right spa filter!

  1. If you have the article number of your filter (may be stamped on the filter), you can search for it below.
  2. Check the type of connection on your filter connection on the filter. Select the correct model below.
  3. Measure the diameter of the connection and choose the right size in the next step.
  4. Measure the length and diameter of the filter and find a filter of a similar size. The size may differ slightly as long as the filter fits in the filter container. The exception is filters with open holes at both ends, where the filter needs to be the same length.

Spa filter

Spafilters are available as washable lamella filters and cleanable Spafilters. The function is similar. The filter removes undesirable particles from the spa water. Skin, hair, make-up, pollen are examples of particles that deteriorate your spa water. Chlorine and other disinfectants remove the bacterial contaminants. Microns are used as a measure of filtration efficiency. A micron, µ, is one millionth of a metre, or 1 thousandth of a millimetre. Cleaning-free spa filters are more effective at removing small particles down to 1-5 microns. A new washable lamella filter is capable of filtering particles down to 20 microns.

Cleaning

Clean and rinse your spa filter at least every 14 days. - Use a spa filter designed for detergents which dissolves grease and other contaminants without damaging the filter media and solder. First roughly rinse the filter and then place it completely in hot water dosed with filter cleaner according to the instructions for use. Leave the filter in place for at least 12 hours before rinsing off the dirt and detergent.

We recommend having two sets of filters for easy and efficient management.

The filter should be changed at least every 12 months to maintain filtration capacity. A poorly cleaned filter can cause both equipment and water quality problems. It doesn't hurt to change the spa filter earlier before 12 months of use. This rule was designed for pool water and a filter has a much harder life in a spa. If you change it in time, you will save on other equipment and get better water.

Cleaning-free spa filters

Cleaning-free filters, are made of many layers of polypropylene. The cleaning-free spa filters are white with a grey bottom and top. 

No cleaning - No filter chemicals - Clearer bathing water. You will simply experience clearer and cleaner water than with traditional disc filters. This at a cheap price while the labour required for filter maintenance is non-existent.

The cleaning-free filter from Sannra™ consists of spun plastic, porous polypropylene, (the same material used in pet bottles). The bath water is filtered each time it passes through the filter, with each layer capturing smaller and smaller particles. This is not a new filter, but these filters have been sold as "originals" in the US, Canada and Europe for Arctic, Astral and as an add-on in Sundance Spas.

We have manufactured new bottom connections, so that we can deliver to many different brands of hot tubs. In recent years, we have sold a lot of this type of filter and people are generally very satisfied and buy the same filter again.

Should be changed every three months for normal bathing.

If you bathe often and frequently, the filter must be changed more often. If you use two filters, change them every 6 months, etc.
