Owner reports

On-site (Yotpo) 1-2 star reviews most often say the salt-free stage did not reduce hardness, spotting or scale (some report TDS rising), with further reports of carbon fines after start-up, pressure loss, missing or wrong parts and late shipments; brand-level complaints (BBB, Trustpilot, on-site) center on slow customer service and the 10% restocking fee.

Trustpilot: 2.9 from 2 reviews (source).

This is the filter + FutureSoft salt-free combo (older reviews sometimes call it 'CF+ with FutureSoft'; on the current site CF+ is only the large filter size). Size flow = lower of the two component ratings (CF1 9 / FS1 12, CF4 12 / FS4 15, CF+ 20 / FS+ 20 GPM). Site-wide banner 'New site, same Springwell - 15% Off All Systems'; prices shown are the sale prices, struck-through MSRP is 15% higher. MSRP: $2,730 / $3,045 / $4,725. Site shows 4.6 from 1,124 reviews. Neighbour combos: Water Filter + Salt Based Softener (CSS1/CSS4/CSS+, $2,231.25-$4,284.00) and 2-in-1 Filter + Salt Softener single-tank MMV-1/MMV-4 (from $2,286.48).
