Specifications
| Price (US) | $1698 $1,698.00 as-configured base system price on aquasana.com (manufacturer page shows "As Configured $1,698.00" with both optional upgrades — Low Maintenance Pre-Filter +$300 and Easy Connect Kit +$100 — set to No).

Source: aquasana.com (verified 2026-07-10) · corroborated by waterfiltercomparisons.com. Verified against the Aquasana manufacturer product page (aquasana.com, model WH-SF40, item 100381840). Its PRODUCT SPECIFICATIONS table confirms verbatim: Grain Capacity 40,000, Rated Flow Rate 11.02 GPM (Peak Flow Rate 15.5 GPM), Salt Storage Capacity 230 pounds, Max Hardness 200 gpg. Body copy states "SimplySoft® uses ion exchange" and "IAPMO certified to NSF/ANSI Standard 44 for the reduction of water hardness and to CSA B483.1." Control interface is described only as a "fully customizable control panel" with an "LCD display" (no WiFi/app; FAQ notes a 12V AC power adapter), supporting smartAppControl=false. The page shows "As Configured $1,698.00" (both upgrades set to No). The page states a "5/10-Year Limited Warranty" but does NOT break out which components carry the 10-year term; the tank-specific 10-year figure is not verbatim on either fetched page (it was previously attributed to a warranty PDF that is not among the fetched source/corroboration URLs), so tankWarrantyYears was nulled. Water Filter Comparisons corroborates the exact WH-SF40 model with "Certified IAPMO 44, CSA B483.1," Integrate Pre-Filter Yes, "Salt Technology No," ion exchange, and a "5/10-year warranty" (its System price of $799.99 is explicitly "accurate as of 9/2/2022"). Iron-removal ppm and numeric salt efficiency are not stated on any fetched page, so both remain null.
