Complete Home Filtration is Australia's most searched whole-home water filter company — and the review picture is more complicated than their marketing suggests. The product delivers real results: better tasting water, reduced chlorine, and genuine customer satisfaction at scale. But three things stand out in our independent assessment that any buyer should understand before signing. Replacement filters are exclusively available from CHF — their 15-inch cartridge format is proprietary and has no aftermarket alternative. The in-home sales model has a well-documented pattern of high-pressure tactics across hundreds of independent reviews. And the NSF certification claim requires careful reading — it covers the filtration media materials, not the complete system. None of this means CHF is a bad choice. It means you should compare quotes, read the filter replacement terms, and not sign at the first appointment.
Complete Home Filtration was founded in March 2018 in a Perth garage by Suzanne Dodds, who had previously run Call-a-Cooler, a national water cooler business, since 2007. From that starting point, CHF has grown into one of Australia's most recognisable water filtration brands, operating nationally across WA, NSW, VIC, QLD, SA and ACT through a network of contracted local plumbers.
The company claims more than 100,000 Australians use their systems and is backed by genuine business recognition: WA Business of the Year, Telstra Best of Business National Winner, AFR Fast 100 inclusion, EY Entrepreneur of the Year finalist status, and Great Place to Work certification. The commercial growth story is real and verifiable.
CHF's model is in-home sales led: a free water assessment is booked, a consultant visits to test water and present a tailored quote, and installation follows through a contracted plumber. The company invests heavily in marketing — including television, radio, and social media influencer campaigns — which drives the high brand awareness and search volume that makes it the most commonly researched water filter company in Australia.
Their flagship product is the CHF-6000 whole-home system. They also offer reverse osmosis under-sink systems and rainwater filtration (sediment plus UV). The head office is at Unit 1/34 Hasler Road, Osborne Park WA 6017.
Scores are based on independently verifiable public data — certifications, published specifications, and review analysis. They are not influenced by advertising or paid placements.
CHF-6000 Whole Home Filtration System — the flagship product. 4-stage whole-home system: sediment filtration → softening resin → activated carbon with KDF-55 → customised final stage. Claimed flow rate up to 48 L/min with less than 5% pressure drop. 1-micron filtration, which is finer than the 5-micron standard used by most competitors. Installed at the mains entry point before the first tee-off, so filtered water reaches every tap, shower and appliance in the home.
The system uses a proprietary 15-inch cartridge format. This is smaller than the industry-standard 20-inch Big Blue format that has become the norm for whole-home systems — particularly for larger households where flow rate matters. The 20-inch format is used by AquaCo, Integraflow, Water2Water, and most other WA-based suppliers because it delivers higher flow and accepts universally available aftermarket cartridges. CHF's 15-inch cartridges are not interchangeable with any standard filter available through plumbing supply, hardware stores, or competing online retailers.
Reverse Osmosis System — under-sink multi-stage RO for drinking and cooking water. Combines sediment and carbon pre-filtration with a semipermeable membrane to reduce fluoride, dissolved salts, heavy metals and pharmaceuticals. Specific membrane specifications and NSF 58 certification status are not published on the CHF website.
Rainwater Filtration — sediment filtration combined with UV disinfection for tank water. Suitable for households on rainwater collection. Specific UV dose and NSF 55 classification are not published.
CHF's website describes media categories — activated carbon, KDF-55, softening resin — but does not publish specific contaminant removal percentages or reference independent testing results. The following table reflects what can be reasonably expected from the documented media types, not CHF-specific verified data.
| Contaminant | Expected Performance | Basis |
|---|---|---|
| Chlorine (free) | High reduction | Activated carbon — industry standard |
| Chloramine | Moderate — depends on carbon type | Requires catalytic carbon; standard activated carbon is limited |
| Sediment / rust | High reduction to 1 micron | Sediment stage claimed at 1 micron |
| Heavy metals (lead, copper) | Partial — KDF-55 based | KDF-55 effective for some heavy metals at contact time |
| Hardness / scale | Reduction via softening resin | Ion exchange resin included as standard |
| VOCs / THMs | Moderate reduction | Activated carbon — performance depends on contact time |
| Fluoride | Not removed | Carbon and KDF-55 do not remove fluoride — RO add-on required |
| PFAS | Not independently verified | No published testing data under current product name |
| Bacteria / viruses | Not addressed by whole-home unit | No UV stage in the standard whole-home system |
CHF's website references "NSF-certified filtration materials" — this is accurate and refers to the media materials meeting safety standards for drinking water contact. It should not be read as system-level certification for contaminant removal claims. For verified NSF 42 or NSF 53 system certification, check nsf.org directly.
The practical difference: WaterMark confirms the system is legally installed by a licensed plumber using approved components. NSF system certification would independently verify the filter's claimed contaminant removal performance. CHF holds the former but not the latter. For buyers who want independent verified performance data, suppliers with NSF 42 and NSF 53 certification provide a higher level of transparency.
CHF markets a UV-protective cover as an Australian-made component — and this is accurate. The external housing enclosure cover is the component manufactured locally. All other parts of the system — filter housings, cartridges, media, fittings and brackets — are sourced internationally from ISO 9000-certified manufacturing facilities.
The "Australian-made cover" marketing claim is technically accurate but should not be taken as meaning the system itself is Australian-made. This is consistent with most water filter suppliers in Australia, where the hardware is typically imported and assembled or configured locally.
The cover specifically has generated a disproportionate number of quality comments in independent reviews. Despite CHF marketing it as UV-stable for Australian conditions, reviewers describe fading within a few years of installation, poor fit after the first cartridge replacement, and difficulty reseating it correctly. This is a minor practical concern but noteworthy given the marketing emphasis placed on it.
What positive reviewers consistently say: The product works. Taste improves noticeably after installation, chlorine smell disappears, skin and hair feel better after showering, and many customers say the change is immediate. The installation experience is generally positive — most describe the contracted plumber as professional and the work as quick and tidy. Post-installation aftercare and the filter reminder service are well-regarded.
What critical reviewers consistently say: The in-home sales consultation experience is the documented concern — not the product. Independent reviews on ProductReview and Google describe a pattern of behaviour: a "one-time only" discount offered at the appointment (commonly $1,500–$1,700 off), a requirement for both partners to be present, prices between $4,800 and $7,500 that drop significantly when the buyer declines, and follow-up calls and messages after the appointment. One reviewer described having to block the salesperson's number. These are independent accounts across multiple years and reviewers — the pattern is consistent enough to flag clearly.
Employee reviews (Glassdoor): Former sales staff describe an aggressive KPI-driven environment with high pressure to close sales. One reviewer noted the product components are equivalent to competitors but CHF charges a significant premium. This context is relevant for understanding the sales model.
CHF occupies a genuinely unusual position: a company that has built real customer satisfaction at scale with a product that works, while using a sales model and pricing structure that independent research consistently flags as problematic. The product outcome and the buying process are two different things. If you proceed, go in informed: get multiple quotes, verify certifications independently, understand the filter lock-in is permanent, and do not make a decision under time pressure at a single in-home appointment.
