This reverse osmosis replacement filter kit from Watts provides a complete one year supply of filters for your RO Pure Plus reverse osmosis system.

Water filters included:

1. Two 5-micron sediment prefilters: These water filters reduce sediment, dirt, rust, and silt from your drinking water.
2. Two 5-micron carbon prefilters: These water filters remove chlorine, tastes, and odors from your drinking water.
3. One 1-micron carbon postfilter: This water filter reduces VOCs, herbicides, and pesticides.

The water filters prepare your water for the reverse osmosis process, and they condition it before and after it goes through the RO system.

How often should you change your water filters?

• Change your sediment filter every 6 months.
• Change your carbon prefilter every 6 months.
• Change your carbon post filter once a year.

How to replace the water filter
Replace your filter in one simple step without turning off your water source. The filters snap in and out simply. Lift the filter and press the button above to remove the old filter. Then, take off the cap on the new filter and snap it in place.

NOTE: These filters will NOT fit the Watts 1/4 turn Kwik Change Reverse Osmosis System. If you have one of these systems visit this page.
