10 Best Rv Water Softeners 2025 in the United States

The On The Go OTG4-DBLSOFT is a portable RV water softener designed for users looking for an efficient way to improve water quality while on the road. 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. This feature makes it an excellent choice for RV owners who value performance and convenience. One standout strength is its compact design, which allows it to fit in tight spaces, enhancing portability and storage. The softener is also easy to install, requiring no tools or electricity, and connects seamlessly to standard garden hoses, which is a big plus for ease of use. The large opening for salt addition and the movable base for leveling on uneven ground further add to its user-friendly design.

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.
