Use each time you fill your spa to eliminate staining caused by organics in unfiltered water. Attaches to a standard garden hose.

Micro Pre-Filter - Starting with Clean Water
With the ever-increasing amount of foreign contaminants found in tap water, it is becoming more necessary to filter this water before filling and topping up your pool or spa. Initial chemical balancing becomes easier, future stain & scale issues are greatly minimized. Micro Pre-Filtration greatly increases OFL (Optimum Filter Life) of your main filters

Our Micro Pre-Filter matrix is designed for general removal of particulates and all visible solids above 1 micron. If you have poor water, this filter is for you. Micron Pre-Filters trap water throughout the entire cross section of the (1 micron) Filter media & not just screen your water like standard pleated filters (40-70 micron). The Micro Pre-Filters will nominally increase your fill times with optimum filtration of your source water.

Directions:

1) Fasten to any standard garden hose
2) Turn on hose till pool or spa is filled to appropriate levels.
3) Replace when filter is full and restricts water.
