Culligan WH-HD200-C Heavy-Duty Whole House Sediment Filter Housing (1 in, bypass valve, cartridge sold separately)

Housing only: sold without a cartridge, so what it treats depends on the cartridge chosen (Culligan heavy-duty 4.5 in cartridges CW5-BBS, CW25-BBS, CP5-BBS, P25-BBS, R50-BBSA, RFC-BBSA). Chlorine taste and odor needs the RFC-BBSA carbon cartridge, which is out of stock on the maker store (as is CP5-BBS). The manual's cartridge chart states the cartridges are 'Not Performance Tested or Certified by WQA'. WQA lists WH-HD200-C (Point-of-Entry) under NSF/ANSI 42, CSA B483.1 and NSF/ANSI/CAN 372 with no reduction claims, matching Culligan's 'WQA / IAPMO tested and certified for structural integrity'; no NSF or IAPMO listing found. The store lists 'Scale' among things filtered; for a sediment housing this means scale particles, not hardness, so hardness is not mapped. Price $73.55 is on Culligan's own DIY store (culligandiy.com, Culligan International Company); CulliganDIY also sells through Ace Hardware and Amazon. Includes built-in bypass valve, pressure-relief button, BR-C bracket, WR-HD wrench and a 90-day filter life indicator. Pressure range is 30-125 psi on the store page but 30-100 psi in the manual; 40-100 F; up to 10 gpm. Weight is the store's shipping weight (4,491 g). Trustpilot score is the brand-level culligan.com profile (dealer service reviews); culligandiy.com has no reviews. Best Buy shows 4 reviews, all 5 stars and incentivized; no recurring complaint found. No CulliganDIY affiliate program found (local Culligan dealers run referral credits only). Rheem was not researched because this Culligan model met the online-price requirement.
