Looking Beyond the On The Go 16,000 Grain RV Softener? 4 Alternatives Worth a Look

01 Comparing the top RV softener alternatives

On The Go 16,000 Grain Portable Softener

This On The Go model shares the same 16,000 grain capacity and 24-inch height as the original, but it is marketed specifically for drinking water use. While the original unit is designed for general RV softening via garden hose, this variant targets travelers who prioritize compact dimensions and drinking water safety. It retains the portable form factor and similar footprint, measuring 10 inches wide and 10 inches long. You get the same reliable conditioning performance, but the focus shifts toward potable water applications. If you need soft water specifically for consumption rather than general household use, this specialized version aligns better with your needs while maintaining the brand's established build quality.

NPGLOBAL 16,000 Grain Portable RV Softener

The NPGLOBAL unit offers a more compact profile, standing 19.7 inches tall with a width of 9.45 inches, compared to the original’s 24-inch height and 10-inch width. It adds a 2-stage filtration system to the softening process, providing basic filtration alongside water conditioning. This makes it suitable for RVers who want to protect their plumbing and skin from both hardness and sediment without installing complex systems. The model is orange and designed for easy storage in tight spaces. You trade the original’s larger physical presence for a smaller footprint and added filtration capabilities. If space is at a premium and you value combined softening and filtration, this budget-friendly option delivers essential protection in a smaller package.

PRO+AQUA 16K Portable Softener

The PRO+AQUA softener matches the original’s 16,000 grain capacity but stands shorter at 20 inches high, with a similar 10-inch width and length. It weighs 35 pounds, slightly more than the original’s 32 pounds, which may affect portability. This model is black and designed for RVers who prioritize capacity in a compact space. It provides a durable, electric-free solution for frequent travelers. While it lacks the specific garden hose connection details of the original, it offers comparable softening performance in a slightly more compact vertical form. If you need high capacity but have limited vertical clearance in your RV, this shorter unit provides a practical alternative without sacrificing grain capacity or requiring electricity for operation.

ShowerSoft Dual-Cartridge Shower Softener

The ShowerSoft system is fundamentally different, designed exclusively for shower use rather than whole-RV softening. It is significantly smaller, measuring only 3.5 inches wide and 11.6 inches high, making it highly portable. This dual-cartridge system focuses on improving shower water quality for skin and hair care, rather than providing large volumes of soft water for general use. It is ideal for renters and travelers who prioritize personal care over whole-house treatment. You give up the high 16,000 grain capacity and general softening capabilities of the original. However, if your primary concern is shower water quality and you need a compact, non-permanent solution, this specialized unit offers targeted benefits in a much smaller form factor.
