Filtration: UF vs RO vs Nanofiltration
The biggest real difference in the lg water purifier vs Coway debate is filtration. LG PuriCare uses Ultra Filtration (UF), which removes 9 types of heavy metals, bacteria and 99.99% of norovirus while keeping the natural minerals in your water. Coway primarily uses Reverse Osmosis (RO), which strips out almost everything — including beneficial minerals — so the water is extremely pure but demineralised. Cuckoo uses Nanofiltration (NF), which also retains minerals and produces mildly alkaline water. For a deeper one-on-one breakdown, read our full LG vs Coway water purifier comparison.
For most Malaysian homes on treated municipal water, UF or NF is more than enough and keeps the minerals your body needs — which is why LG and Cuckoo retain minerals while RO does not. See also our detailed LG vs Cuckoo water purifier comparison.
Tankless vs Tank: Hygiene & Power
LG PuriCare is tankless: it heats and cools water instantly, on demand, with no storage tank. That means no standing water sitting around (more hygienic), a slim 13cm footprint, and no energy wasted continuously reheating a tank. Coway models are mostly tank-type (plastic), and Cuckoo typically uses a stainless-steel tank — both reheat stored water to keep it hot, which can use more electricity. A tank does have one upside: stored water remains available during a supply disruption.
Price & Total Cost over 7 Years
LG PuriCare has the lowest entry rental in Malaysia from RM17/month (WD516AN), and the package includes a free 7-year filter subscription and warranty with self-service — so there are no surprise filter or service bills across the rental term. Coway and Cuckoo rentals typically start higher and bundle technician visits, which is convenient but usually costs more over the full contract.

Frequently Asked Questions
Is the LG water purifier better than Coway?
It depends on what you value. LG PuriCare uses tankless UF that removes 9 heavy metals and 99.99% of norovirus while keeping natural minerals, plus instant hot water and a slim design from RM17/month. Coway mainly uses RO, which removes more dissolved solids but also strips minerals. Choose LG for tankless hygiene, mineral retention and lower price; choose Coway if you specifically want RO.

LG PuriCare uses Ultra Filtration (UF), not Reverse Osmosis. UF removes heavy metals, bacteria and viruses while retaining beneficial natural minerals.
