SoftPro vs Aquasure: common questions
Why does the SoftPro Elite cost more than Aquasure?
The price difference buys a longer guarantee and warranty. SoftPro gives you 6 months to return the system with no restocking fee and covers the tanks and control valve body for life. Aquasure gives 30 days, charges 15% to 50% to restock, and covers the valve for up to 5 years if you register it.
Which is better for iron in well water?
Aquasure rates its fine mesh model for up to 10 ppm of iron. SoftPro rates the Elite for Well Water for up to 3 ppm of clear-water iron and recommends the SoftPro AIO Iron Master, rated up to 30 ppm iron and 7 ppm manganese, ahead of the softener when iron is higher.
Can I install either one myself?
Yes. Both are sold online for homeowner installation. SoftPro includes installation guides and videos, and our technicians help by phone or video.
