It isn't hard water. It's chlorine.
What PUB puts in the supply, why it's safe to drink and harsh on skin, and what a filtered showerhead does about it.
Do you know what's in your shower water?
Most tap water is filled with invisible contaminants that quietly damage your skin, hair, and health. In Singapore it isn't hard water. It's chlorine. Tap one to see what it does.
PUB disinfects the whole supply with chlorine. It keeps the water safe to drink, and it reaches every shower in Singapore at a low residual level by design.
Chlorine oxidises the natural oils and lipids that hold your skin barrier together. It shows up as tightness after a shower, dry patches, redness, and flare-ups that never quite settle. On hair it lifts the cuticle, which reads as frizz and breakage.
Halo's calcium sulfite stage removes 99.9% of chlorine at shower temperature and pressure, before the water touches you.
Before HaloAfter HaloChlorine bonded to ammonia so it lasts longer in the pipes on the way to your tap. It does not gas off the way plain chlorine does.
Because it lingers in the water, it lingers on you. Itchy scalp, redness and a tight feeling that a moisturiser only masks are the usual complaints, and sensitive or eczema-prone skin notices it first.
Cleared by the same calcium sulfite stage, which is built for chloramine as well as chlorine.
Before HaloAfter HaloTrace lead, iron and other metals picked up from old pipes and fittings between the treatment plant and your shower, more so in older blocks.
Metals bind to hair and build up on it, leaving it dull, heavy and prone to breakage. On skin they add to the irritation load that keeps a compromised barrier from settling.
Halo's KDF-55 copper-zinc stage pulls heavy metals out of the stream as it passes.
Before HaloAfter HaloLeached from copper plumbing, especially after water sits in the pipes overnight or in a unit that has been empty for a while.
Copper dries hair, dulls colour, and can leave a green tinge on lighter or bleached hair. On skin it is one more irritant a sensitive barrier does not need.
Captured by the KDF-55 stage.

They settle on skin and in pores with every rinse. For breakout-prone skin that is a daily layer of particles you did not put there and cannot wash off with the same water.
Halo's PP cotton cartridge in the handle catches particles down to 1 micron.
Before HaloAfter HaloBacteria and biofilm that grow inside warm, wet pipes and shower hoses, which in Singapore means every hose, all year.
They sit on skin after every shower and feed breakouts and irritation on compromised skin, the opposite of what a shower is for.
Trapped by the 1-micron PP cotton stage before the water reaches you.

What chlorine does to skin
Residual chlorine oxidises the lipids that hold your skin barrier together. It shows up as tightness after a shower, dry patches, and flare-ups that never quite settle. Singapore's tap water carries residual chlorine to every home by design; it is what keeps the supply safe.
What it does to hair
Chlorine lifts the hair cuticle and strips the oils that keep it smooth, which reads as frizz, breakage and a scalp that itches. Colour fades faster. The fix is at the showerhead, before the water touches you, not in another product afterwards.
Two cartridges. Four filter media. One clean shower.
Great skin and hair start with clean water. Halo filters your shower in two places: a PP cotton cartridge in the handle that catches rust, sediment and micro-plastics, then a three-stage cartridge in the head that removes chlorine, chloramine and heavy metals. Tap a cartridge on the right to see what's inside.
