How to choose the right one
-
Check physical dimensions
You must verify that the unit fits your available space before purchasing. The NPGLOBAL model measures 9.45 by 19.7 by 9.44 inches, making it the most compact option on this list. The On The Go units are slightly larger at 10 by 24 by 10 inches. Measure your storage area carefully to ensure the softener fits comfortably. Portability is key for RV owners, so a smaller footprint allows for easier transport and storage when the vehicle is in use.
-
Confirm grain capacity
All three models listed share a 16,000 grain capacity. This specification indicates the amount of hardness minerals the resin can remove before regeneration is needed. This capacity is standard for portable units designed for RVs or boats. You do not need to compare different capacity levels here since they are identical. This consistency ensures that any model you choose will offer similar performance regarding water softening volume before maintenance is required.
-
Identify filtration stages
Consider whether you need additional filtration beyond softening. The NPGLOBAL model features a 2-stage filtration system, which may provide extra sediment removal compared to the other options. The On The Go models are described primarily by their softening capabilities and portable design. If you require cleaner water for drinking or cooking, the multi-stage filter on the NPGLOBAL unit might be a practical advantage for your specific needs.
-
Assess weight and portability
You should evaluate the weight if you plan to move the unit frequently. The On The Go RV Softener weighs 32 pounds, which is a factor to consider for manual handling. The other models do not list specific weights in the provided data. A lighter unit is easier to maneuver in tight RV spaces or during travel. Ensure you can lift and position the softener safely within your vehicle or storage area without difficulty.
-
Verify intended use
These units are designed for portable applications like RVs and boats, not whole-home systems. You cannot connect them to your house plumbing. The On The Go 16,000 Grain Portable Softener is noted for filtering drinking water, which adds versatility for campers. The NPGLOBAL model is suitable for general RV water softening. Ensure your expectations align with portable use only, as these devices cannot serve stationary residential plumbing systems.
Frequently asked questions
Can these portable softeners replace a whole-home system?
