Doulton Water Filters

What Doulton Water Filters does

Doulton Water Filters, trading under Fairey Industrial Ceramics Limited and founded in 1826 in Staffordshire, England, manufactures and sells ceramic water filtration systems primarily to residential consumers. The company's core technology is a proprietary ceramic filter element made from natural earth materials, available in variants including Biotect Ultra, Ultra Sterasyl, and Ultra Fluoride, certified to reduce up to 99.99% of common contaminants such as bacteria, cysts, microplastics, chlorine, PFAS, lead, cadmium, and mercury. The product portfolio spans under-sink systems (Kingfisher, HIP DUO, HIP TRIO, HIS Push-fit, Ecofast), countertop systems, British Berkefeld stainless-steel gravity-fed systems (1L to 12L), portable bottles, shower filters, and a family of specialized pre-filter cartridges (fluoride, nitrate, limescale, PFAS/chlorine). All ceramic filter elements are manufactured in-house at the company's Newcastle-under-Lyme and Longton (Stoke-on-Trent) facilities in Staffordshire, with the company holding the Made in Britain mark, NSF/ANSI 42/53/401/372 certifications, WRAS approval, BS EN ISO 9001, and WQA certification.

The business model is a hybrid of one-time hardware sales and recurring consumable revenue. Systems are sold direct-to-consumer through the company's Shopify-based e-commerce storefront across UK, US, EU, and Canadian markets, complemented by a trade distribution channel through plumbers and installers (including InstallerSHOW 2026 engagement) and a Subscribe & Save subscription program delivering replacement filters every 6 months at a 20% discount. The company also operates a Doulton Rewards loyalty and referral program, an educational content and quiz-driven funnel, and a sub-brand (British Berkefeld, held since the early 1900s) targeting the outdoor, prepper, and off-grid segments. Customer segments are predominantly residential homeowners, renters, the outdoor/prepper community, and trade installers — none concentrated as enterprise accounts. Revenue figures are not publicly disclosed; the company employs 51-100 people and operates without external funding rounds.

Core offering

Doulton Water Filters manufactures ceramic water filtration systems for residential and portable use, including under-sink, countertop, gravity-fed, and shower/water-bottle units. The company sells proprietary ceramic filter cartridges (Biotect Ultra, Ultra Sterasyl, Ultra Fluoride) plus targeted pre-filter cartridges (fluoride, PFAS, nitrate, limescale, chlorine) and runs a Subscribe & Save replacement filter subscription service. The portfolio is sold primarily through the company's own e-commerce storefronts in the UK, US, and EU.

Product overview

Doulton Water Filters offers a comprehensive portfolio of ceramic water filtration products and systems designed for residential use. The product range comprises three main system categories: under sink water filter systems (including Kingfisher, HIP DUO, HIP TRIO, HIS Push-fit, and Ecofast models), countertop water filter systems, and gravity-fed water filter systems under the British Berkefeld sub-brand. The core technology centers on ceramic water filter cartridges including Biotect Ultra, Ultracarb, and Ultra Sterasyl variants that reduce up to 99.99% of common contaminants including bacteria, cysts, microplastics, chlorine, PFAS, heavy metals, and sediment. The product ecosystem includes specialized pre-filter cartridges for targeted contaminant reduction (fluoride, nitrate, limescale, PFAS, chlorine), replacement filters with 6-month replacement intervals, and accessories including installation kits, taps, and tubing. The company also offers portable filtration solutions (water bottles, shower heads) and bundle packages. All ceramic filter elements are manufactured in Staffordshire, UK, and products are independently certified by NSF International and WRAS.

• PUR: PUR (owned by Helen of Troy) makes faucet-mount and under-sink water filtration systems sold through mass retail. Directly comparable to Doulton's countertop and under-sink product lines, targeting similar residential households at comparable price points.
• Berkey Filters: Berkey is the leading US-based competitor in the gravity-fed stainless steel water filter category, directly overlapping with Doulton's British Berkefeld sub-brand. Both sell multi-element gravity systems targeted at preppers, off-grid users, and homeowners seeking plumb-free filtration.
• Aquasana: Aquasana (owned by A. O. Smith) sells under-sink, countertop, and whole-home water filtration systems with NSF-certified contaminant reduction claims. Directly comparable to Doulton's under-sink range and emphasizes third-party certification as a key differentiator.
• ZeroWater: ZeroWater markets pitcher and under-sink filtration systems with TDS meters, competing in the same residential replacement-filter-driven business model as Doulton. Comparable on DTC go-to-market, replacement cartridge subscription economics, and premium positioning.
• Brita: Brita (owned by Clorox) is the dominant global pitcher and under-sink water filtration brand and Doulton's closest direct competitor in the residential ceramic/carbon filter category. Both target health-conscious households with point-of-use filtration systems and replacement cartridges.
