With a grain capacity of 16,000, it produces approximately 1,600 gallons of soft water and regenerates quickly using just two boxes of table salt in under 30 minutes.

However, there are some drawbacks to consider. While the softener can provide substantial soft water, its effectiveness can vary based on the hardness of your water source. If your water is particularly hard, you may find that the capacity can be somewhat limited. Maintenance is generally straightforward, but users will need to regularly manage salt levels and monitor the system to ensure optimal performance. The unit weighs 32 pounds, which may be somewhat heavy for some users to handle, especially during relocation or setup.
