Indoor Natural Filtration

ClearSpring Biofilter

Our unique, cutting edge biofilter is the only vessel based natural pool filter in the world. It prevents any algae or harmful bacteria from being able to grow by starving them of the essential nutrition they require. Find out more at the knowledge base.

Lower running costs

The ClearSpring filter has been designed with efficiency in mind. The lower water turnover frequency of our swimming pools compared to old-style chlorine pools mean lower energy bills.


As our technology does not require plants to filter the water, CWR’s natural swimming pools can be easily covered, fully insulated and heated up to 32 degrees with minimal heat loss and associated running cost.

Less maintenance

Because all Clear Water Revival swimming pools are 100% chemical free, pumps and filters last longer and pool hall degradation is reduced due to the elimination of chemical gas-off.

There is no need for any chlorine dosing due to our ClearSpring natural biofilter ensuring the time and effort spent on maintaining your indoor pool is significantly reduced.


Basement Swimming Pools

If you want to avoid using chlorine in your basement swimming pool project and prevent the associated chemical odors from taking over your home, the ClearSpring system is the answer. We are the only company capable of creating a naturally filtered basement swimming pool.
