PuraSpa filters are manufactured in the same USA plant as the original Micropure disposable filters. They are identical and still made to the same high standards as those made by Micropure. The quality and performance will not dissapoint. They filter much better, last far longer, and don't have the flow issues of knock-off filters imported from China.

Directions for use:

  • Place filter in spa and don't check filter for at least 2 months.
  • The filter will start to discolor from the outside in. When you can not see any white in the center of the filter, it is time to replace.
  • Expansion of the filter material is normal as it absorbs and removes debris - filtration improves as it expands.
  • Do not use defoamers, clarifiers, cleaners, stain and scale mineral removers or descummer chemicals. These chemicals are not necessary with Micron filters and will reduce the life of the filter because the filter will absorb these oils. If you have been using these chemicals in your water, drain your water before switching to Micron disposable filters.
  • Do not clean or rinse filter - simply replace when it is full. Micron filters have been tested to last up to 5 months for low bather loads, but it is recommended to replace after 3 months for optimal filtration.
