SoftPro Fortress review

Our verdict

The SoftPro Fortress is the cheapest way into salt-free scale prevention: $529 for the Pro model at 10 GPM, with a 99.6% scale prevention claim from SoftPro. Media lasts about 5 years. Skip it if you want more than a 1-year warranty, or a money-back period, which the page does not state.

Great if

  • you want salt-free on a budget
  • you want a compact 22.5" cartridge housing instead of a tank
  • your hardness is under 75 gpg

Skip it if

  • your water has more than 2.0 ppm of chlorine without pretreatment: that voids the warranty
  • you want a long warranty
  • you want soft water

What living with it looks like

Instead of a tank, the Fortress uses a 22.5" cartridge housing with template-assisted crystallization media. SoftPro rates the media at about 5 years in the Pro model. The Home model, for 1-2 bathrooms at 6 GPM, costs $229 but needs new media every 2 years.

We compare the Pro model at 10 GPM, which SoftPro sizes for about 3-4 bathrooms. It is the size that matches the flow of the other systems here.

What it does not need is the selling point. No drain, so it can hang on a garage or closet wall; no outlet; no salt to carry. The housing goes on the main line before the water heater, ideally after a sediment filter so that sand and grit do not coat the media.

The catch

Short coverage. The warranty is 1 year, and no money-back period is stated on the product page. The certification is IAPMO R&T to NSF/ANSI/CAN 61, which covers material safety, not the scale claim. And chlorine above 2.0 ppm without pretreatment voids the warranty.

A sizing note: SoftPro sizes the Pro for about 3 to 4 bathrooms, a step above the 1-3 bathroom size we use for most systems. We chose it because the Home model's 6 GPM is low for a family. If you live alone or as a couple in a small home, the $229 Home model is the cheaper fit, with new media every 2 years.

Buying advice

Check your chlorine level in your city report. If it is near 2.0 ppm, add a carbon filter in front. Budget the media change every 5 years.

Against the other two conditioners here, the Fortress costs $1,229 less than the Aquasana and $1,571 less than the SpringWell FutureSoft. What the difference buys is coverage: 1 year of warranty here, against 10 years and lifetime there.

  • Template-assisted crystallization: prevents 99.6% of scale buildup, per SoftPro
  • Media lasts about 5 years in the Pro model (every 2 years in the Home model)
  • Hardness limit 75 grains per gallon; continuous flow 6 GPM
