Product Information

The Hydronix 40" String Wound Water Filter is the economical replacement for the Liquatec SWF-25-4020 Filter. Made from 100% polypropylene fiber media cord, this 20 micron filter reduces particles and waterborne contaminants like dirt, sand, silt, sediment and scale. Different wound patterns are based on different micron ratings to ensure that you get the appropriate filter for your specific applications.
Also known as PP Filter or part number SWC-25-4020, the Hydronix string wound filter has a high flow rate and dirt holding capacity. It fits standard size water filter housings that require a 40" x 2 1/2" media. This string wound water filter can be used in municipal or well water, although water that is microbiologically unsafe or of unknown quality should not be used without adequate disinfection.
