Water Quality in Ultimo Apartment Buildings
Many Ultimo residents live in buildings served by rooftop cold-water storage tanks. Water travels from Sydney Water's mains, up through the building and into these tanks before flowing to your tap, meaning it can pick up sediment, bacteria and other contaminants along the way. On top of this, Sydney Water treats its supply with chlorine and chloramines to keep it safe during distribution, but these disinfectants have a noticeable taste and smell that many residents find unpleasant. A quality under-sink filter or reverse osmosis system addresses both concerns at the point of use, your kitchen tap.
Affordable Options Starting at $550 for Ultimo Residents
Not every Ultimo resident wants or needs a full reverse osmosis system. The Pure Essential Twin Stage ($550 all-inclusive) is an excellent entry-level option that removes chlorine, sediment and taste-and-odour compounds from your drinking water. Installation takes around 1.5 hours, requires no structural modifications, and the system fits neatly within your standard kitchen under-sink cabinet. For residents who want comprehensive filtration, removing fluoride, heavy metals and microplastics, the Pure Plus+ 5-Stage RO ($840) is the most popular upgrade.
Renter-Friendly Reversible Installation
If you're renting in Ultimo, a water filter is still a realistic option. Jean-Paul's under-sink installations are fully reversible, the system connects to the existing cold water supply tap under the sink without cutting pipes or making permanent changes to the property. When you move out, the system can be uninstalled in under 30 minutes and taken with you to your next home. No bond deductions, no landlord drama. Jean-Paul can advise on the best reversible configuration for your property when you call to enquire.
Under Sink Water Filtration for Ultimo
For Ultimo households looking for a practical, cost-effective improvement to their drinking water, an under-sink filter is the entry point. The Pure Essential twin-stage carbon filter ($550) removes chlorine, sediment, taste and odour with a fast flow rate and low ongoing maintenance, cartridge replacements run around $80–$120 per year. The system fits neatly inside your kitchen cabinet with a dedicated filtered-water tap on your benchtop, leaving your existing mixer tap untouched. Installation typically takes 1.5 to 2 hours and works in any Ultimo property type, apartment, terrace, townhouse or freestanding home.
For Ultimo residents who want more comprehensive filtration without going to a full reverse osmosis system, multi-stage carbon options up to 7 stages are available. Jean-Paul will recommend the right configuration based on your water quality concerns and household priorities. Browse the full range on the under sink water filter page.
Reverse Osmosis Water Filtration for Ultimo
For Ultimo households who want the absolute best drinking water quality, water that genuinely rivals premium bottled water, a reverse osmosis system is the right choice. The Pure Plus+ 5-Stage Reverse Osmosis system ($840) uses a semi-permeable membrane to physically remove up to 99% of dissolved contaminants including chloramines, fluoride, nitrates, heavy metals, PFAS compounds and microplastics. The system fits under your kitchen sink and delivers filtered water through a dedicated tap on the benchtop. Annual cartridge and membrane maintenance typically runs around $150–$200.
For Ultimo families with young children, anyone preparing baby formula with tap water, or households prioritising long-term health, RO is the clear step up from a standard carbon filter. Higher-stage options (Pure Premium 7-Stage at $1,180, Pure Luxe smart RO at $1,520) are also available for premium configurations. Browse the full range on the reverse osmosis water filter page.
Whole House Water Filtration for Ultimo
For Ultimo homes with accessible mains water connection, typically houses, townhouses and some ground-floor or low-rise apartments depending on the building's layout, the HPF-3 Whole House System ($3,150–$3,550) is the most comprehensive water filtration option available. Connected at the water mains, the HPF-3 filters every outlet in the property: kitchen taps, bathroom taps, showers, baths, washing machines, dishwashers and outdoor taps. Final pricing depends on installation conditions (water meter accessibility and pipework configuration), and Jean-Paul will inspect your property to confirm suitability and quote the fixed price before any work begins.
For Ultimo households, the benefits of whole house filtration go beyond drinking water alone. Chlorine-free water means softer hair and skin (a difference many homeowners notice within the first week), every appliance benefits from cleaner water (extending the life of dishwashers, washing machines and hot water systems), and you have one integrated system to maintain rather than multiple point-of-use filters. Whole house is the right step up for Ultimo households who want filtered water at every tap, not just one, and have the property type that supports it.
