Filters

We offer WISY products: the best in rainwater harvesting worldwide!
Our systems require minimum maintenance and will last a lifetime.

Rainwater from the roof generally should be filtered with a fine filter before entering the storage tank.  For non-potable (water not suitable for drinking) uses there is no need for additional filtering either on the suction or pressure side of the pump.  Conventional roof washers retain moisture and create an area which will promote the growth of bacteria on the filter insert.

The simple but high precision WISY filters use surface tension (adhesion) in conjunction with a fine stainless steel filter mesh which excludes unwelcome debris. By this process about 90% of the rainwater is captured, filtered and diverted into a storage tank, while the remaining water carrying leaves and other debris is redirected to the ground or soak away.
