NOT an ionizer · under-sink filter

3M is the most-installed under-sink filter brand in Singapore — go into almost any home renovation supplier and the 3M AP Easy Complete is on the list. Important: 3M sells filtration cartridges, not multi-plate alkaline ionizers. The output is filtered (typically improved chlorine / sediment removal) at room-temperature pH. If you want hot/cold or ionized water, look at a different category.
