Activated Carbon Cartridges
Rainfresh LR1 filter cartridges are ultra-high performance activated
carbon filters designed to reduce Lead, Trihalomethanes (THM),
Volatile organic compounds and Chlorine from potable water. They
are also highly effective in improving water taste and odour.
LR1 cartridges are made from high quality activated carbon
constructed in a proprietary compact style to deliver high adsorption
performance and excellent contaminant removal characteristics.
The LR1 filter has been independently tested and certified by CSA
International to ANSI/NSF standard 53* for reduction of Lead, VOC Efficient Reduction
(see below for list) & THM. It has also been tested and certified under of Lead
ANSI/NSF standard 42* for reduction of chlorine, taste and odour.

NOTE: Not intended for making microbiologically safe water. If used on untreated water, adequate disinfection should be carried
out before the filter.
LR1 cartridges perform best when used with Rainfresh models UCCSM, UCS2, DS2, UCS3, DS3 &
CT500*. However, they also fit and perform when used with competitive* 10” filter housings.
