The On The Go OTG4-DBLSOFT-Portable 16,000 Grain RV Water Softener is a robust option for RV owners looking for a reliable and efficient water softening solution. Its standout feature is its 16,000 grain capacity, which is significantly higher than many other models, making it ideal for extended use, supplying up to 1600 gallons of soft water or lasting up to 40 days between regenerations.

The regeneration process is simple and swift, taking less than 30 minutes using common table salt, which is very convenient for users on the go. Additionally, it boasts a compact design with dimensions of 22”H x 9.50” diameter, making it easy to store in tight spaces within an RV or marine vehicle. The easy-to-carry handle and large mouth opening for salt addition enhance its usability, while garden hose connections make installation straightforward without requiring any tools or electricity.

The high flow rate with minimal pressure drop ensures a consistent water supply, which is essential for maintaining comfort during travel. Durability is a strong point, as it is assembled in the USA with high-grade premium resin, promising long-term reliability. However, the weight of 32 pounds may be cumbersome for some users, and the cost could be higher compared to smaller capacity units. Also, while it is not made in China, which might be appealing to some buyers, the 40% more soft water claim versus other units may depend on specific use cases and water hardness levels, potentially varying the user experience.

The GLACIER FRESH Portable RV Water Softener is a solid choice for RV owners and anyone needing soft water on the go, such as boaters or mobile car washers. Its 16,000-grain capacity is notably high for portable softeners, meaning it can treat hard water longer before needing regeneration. This helps prevent scale buildup and reduces unpleasant tastes and odors by removing minerals like calcium, magnesium, and iron. The unit is built with a rugged stainless steel tank and quick connect hoses, which makes it durable and resistant to rust—important for outdoor and mobile use.

Installation is straightforward and tool-free, with quick connects that easily link to garden hoses, making set-up at campgrounds or other water sources quick and hassle-free. Weighing about 28 pounds, it’s portable but not ultra-light, so it’s best suited for users comfortable with a moderate size unit. Since it doesn’t require electricity, it’s convenient for remote locations where power may be limited.

This water softener offers good durability, a high capacity, and ease of installation, making it a practical option for RV users wanting improved water quality without complicated setup or maintenance. However, if extremely lightweight or faster flow rates are a priority, you might want to explore other models.

The VEVOR RV Water Softener is a portable unit designed to improve water quality for RVs, trailers, boats, and other mobile applications.

This water softener does not require electricity, making it ideal for camping and various outdoor activities. It also maintains a large flow and high pressure, with a maximum pressure rating of 150 psi, ensuring minimal impact on water pressure.
