Elexa Home Filtration grew from an existing plumbing and gas services operation with over 25 years of trade experience. The founders expanded into residential water filtration based on direct experience with water systems rather than as a dedicated filter sales business — a background that shows in how they present themselves to customers.

Their core differentiator, repeated consistently across their website, is that customers deal with plumbers rather than salespeople. Every installation is carried out by qualified, licensed plumbers employed directly by Elexa rather than contracted through a third party. This matters: much of the inconsistency in installation quality reported across the Perth filtration market comes from suppliers who outsource to independent contractors with varying skill levels.

The business serves the Perth metropolitan area and offers no-obligation water quality assessments before recommending a system. Services cover the main residential categories: whole-home entry-point filtration, under-sink systems (including reverse osmosis options), and water softeners for hard water management. Ongoing maintenance and servicing is offered as a separate service.

Where data could not be independently verified, this is noted against each score criterion.

Whole-Home Filtration — Entry-point systems treating all water before it enters the home. Specific filter stages, housing sizes, and media not published. Intended to address chlorine, sediment, and general water quality for drinking, bathing, and appliances.

Under-Sink Filtration — Point-of-use systems for kitchen drinking water. Includes standard carbon filtration and reverse osmosis options. Suitable for households wanting higher purity at the drinking tap without whole-home treatment.

Water Softeners — Salt-based or alternative softening for hard water management. Relevant for Perth households dealing with scale buildup on appliances, shower screens, and plumbing fixtures.

Maintenance and Servicing — Ongoing filter replacements and system servicing. Carried out by the same licensed plumbers who installed the system.

The testimonials published on the Elexa website are consistent in two themes: satisfaction with installation quality, and appreciation for dealing with plumbers who gave genuine technical advice rather than a sales pitch. One customer notes noticing the water quality difference immediately after installation of a chlorine-reduction system. Another praises same-day responsiveness for a hot water system issue.

The plumber-not-salesperson positioning is credible given the business origin — it is harder to fake when your staff are qualified tradespeople with a plumbing ticket rather than recruited sales staff. That said, independent third-party review data (Google, ProductReview) is needed to fully validate this reputation.

Elexa presents well as a tradesperson-led operation with the right values for a transparent filtration business. The score of 7.0 is provisional — the ceiling is higher if WaterMark certification is confirmed and Google reviews support the honest-advice reputation. This is a supplier worth requesting a quote from alongside one or two certified alternatives so you have a genuine comparison.
