Your purchase comes with a single tank, bypass valve, drain hose, 3 installation adaptors, 4 O-rings, 2 hose clamps, 5 clips, a grommet, and adaptor elbow.
Measuring at 48” x 41.5” x 17” x 21” x 3.75”, this is an average-sized unit which is easy to install, low maintenance, and high-quality. North Star’s U.S.-based manufacturing facilities produce 95% of all its machine components, giving it exact control over its work quality.

2. North Star NSRO42C4 Reverse Osmosis Filtration System: Best for the Money
The North Star NSRO42C4 is a reverse osmosis filtration system. If you’re looking for a cheaper way to get top-quality, great-tasting water, an RO system, such as the NSRO42c4, can achieve great things at a fraction of the cost.
RO water is naturally soft water; its filtration process removes the calcium, magnesium, and other minerals, which cause hard water.
This North Star model is made to provide great-tasting drinking water right at your sink. Its compact design is made for an under-the-sink set-up or can even be installed at your refrigerator.
The faucet, which comes as part of your purchase, is made from stylish chrome and is entirely lead-free.
This model features an efficient 3-part filtering process, using the pre-filter, membrane, and post-filter. By using all these filters, this model can remove chlorine and sediment, inorganic and organic contaminants, chemicals, and metals.
Use the water quality monitor, placed at the faucet base, to assess when it’s time to change the filters. Red indicates the membrane needs to be changed, yellow indicates the pre/post filters need to be changed, and green indicates the pre/post filters are operating optimally.
Typically, the pre- and post-filters will need to be changed every 6 months, while the membrane is good for 2 years. Simply replace these components by using the twist-and-pull sanitary filters. You can EASILY purchase replacement parts for your North Star water softener online; just make a note of the model to ensure you’re buying the correct part.
