PuraSpa® 1 Micron Filters have huge advantages!

  • Use less chemicals
  • Enjoy cleaner water
  • No filter cleaning

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 filters previously made by Micropure. You will not be disappointed with quality PuraSpa® filters. They filter much better, last much longer, and don't have the flow issues of knock-off filters imported from Asia.

Directions for using PuraSpa® 1 Micron Filters:

  • 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 the filter absorbs and removes debris, the filter expands and filtration improves.
  • Do not use defoamers, clarifiers, cleaners, stain and scale mineral removers or descummer chemicals. These chemicals are not necessary with 1 Micron filters. These chemicals also reduce the life of our filters, because our filters remove these oils. If you have been using these chemicals in your water, drain your water before switching to 1 Micron 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.
