Purest Water Filtration is a Central Coast–based installer led by licensed plumber Ben (NSW Contractor Licence #305926C), covering a wide regional footprint from Sydney through the Central Coast, Newcastle and Hunter up to Port Macquarie. Systems are WaterMark + NSF certified and backed by a 5-year warranty on both product and installation. The main gaps are the absence of upfront system pricing and some inconsistent self-reported figures on the site.
Purest Water Filtration is a home filtration installer based at Erina on the NSW Central Coast, led by Ben, a licensed plumber (NSW Contractor Licence #305926C) with Certificates III & IV in Plumbing, Drainage and Gas Fitting. The business installs whole-house and reverse osmosis systems across a broad regional footprint — Sydney, the Central Coast, Wollongong, Lake Macquarie, Newcastle, Forster and Port Macquarie.
Its strengths are solid: a published and verifiable licence number, WaterMark and NSF certified systems, an in-house team rather than subcontractors, and a 5-year warranty covering both the product and the installation. The wide regional coverage is a genuine point of difference — much of the Hunter and Central Coast is poorly served by the Sydney-centric installers.
The limitations are around transparency of detail rather than credentials. There is no upfront system pricing (the business quotes per job, though it does publish payment-plan terms), and some self-reported figures on the site are inconsistent — experience is described as both "20+" and "8+" years in different places, and install counts vary. To its credit, the site also carries an honest disclaimer making no health or water-quality guarantees. On balance, a dependable regional specialist at 7.4.
