Pure water at home with the Aqualife RO Water Filter
A six-stage alkaline RO system with an 18 litre tank, automatic 24 V DC operation, clear pricing, installation support, and access to compatible replacement filters.
Installment option: LKR 15,000 upfront + LKR 5,990 × 10 months = LKR 74,900 total.
Clean water made practical
A complete home RO system, not only a sediment cartridge
Water moves through sediment and carbon filtration, an RO membrane, post-carbon treatment, and a mineral alkaline cartridge before reaching the dedicated drinking-water tap.
- Visible sediment control: a 5 micron pre-filter and 1 micron sediment stage address sand, rust, mud, and suspended particles.
- Taste and odour treatment: carbon stages help with chlorine-related taste and odour.
- RO treatment: the membrane is the main stage for reducing dissolved solids and selected contaminants.
- Final conditioning: post-carbon and mineral alkaline stages polish and condition the water.
How the system works
Six filtration stages in one clear water path
The stage order is kept consistent across our product information, service guidance, and replacement-part pages.
5 micron pre-filter
First barrier for visible sediment such as sand, rust, mud, and suspended particles.
1 micron sediment
Captures finer suspended particles before the carbon and RO stages.
Inline carbon
Helps reduce chlorine-related taste and odour and helps protect the RO membrane.
RO membrane
Main reverse-osmosis stage for reducing dissolved solids and selected contaminants.
Post-carbon
Final taste and odour polishing after the storage stage.
Mineral alkaline
Conditions the final water and supports the target outlet pH range.
