Your tap tested hard.
Here's what that means.
You commented HARD and saw the reading. Here are two simple ways to go from here — no pressure either way.
Test your own tap
Want your own number before deciding anything? A home hardness tester gives you a reading in under a minute, so you know where you actually stand.
- Reading in under a minute
- An easy first step before you decide on a fix
- A simple, affordable way to check your tap
Good to know: a home tester gives a fast, useful read — it's not a certified lab result. For an official number, a lab test is the way to go.
Get a filter
Prefer to skip the test and start handling the buildup? A hardness filter is built specifically to reduce the minerals that turn into limescale.
- Targets the minerals that cause scale
- Helps protect your kettle, boiler, and skin
- Backed by AquaStandard — more on that below
Hard water just means more calcium and magnesium than usual.
It won't make you sick. But over time, those minerals turn into limescale — a hard, chalky buildup inside anything that heats water. Kettles, boilers, pipes, and yes, your skin can all show it. A lot of tap water across Armenia falls somewhere in this hard range — we're mapping the exact numbers region by region as the expedition goes.
Exact numbers per marz are still being logged as the expedition tests each region — this page will update as that data comes in.
What limescale can look like up close.
These are common examples — not staged, not exaggerated.
Quick answers
Is hard water risky to drink?
Yes. Hardness is a mineral level, not a contaminant. It affects your appliances and skin far more than your health.
How accurate is a home tester compared to a lab test?
A home tester gives you a fast, useful read, but it isn't the same as a certified lab result. If you want an official number, a lab test is the way to confirm it.
What's the difference between hard water and high TDS?
Hardness measures calcium and magnesium specifically. TDS measures everything dissolved in the water. Water can be hard without high TDS, and vice versa — different test, different number.
Does a filter fully fix hard water?
A dedicated hardness filter reduces the minerals that cause scale. It's not a full reverse-osmosis setup, but it handles the kettle, boiler, and skin problem most people are testing for.
