The most innovative rain cistern pre-filter on the market - the Monjolin Mini!

Developed in Brazil, we have worked with the manufacturer to import this filter because of its ingenuity and effectiveness. This is the ONLY pre-filter to effectively filter down to 136   microns while sending leaves and debris straight through and out the discharge point, making it LOW MAINTENANCE. The mini-Monjolin has an access panel on both sides of the unit, giving it the versatility to be mounted to discharge debreis to the right or the left. Additionally, at a fraction of the price of other pre-filters, it is ideal for creating an affordable and clean rain cistern system.

RECOMMENDED FOR homes and cabins with 1-4 downspouts feeding a cistern used for drinking water. One filter needed per downspout. Bulk discounts available.
