For years we have Pure filter system, Check it with a tester and the PPM is the same as the mains tap on the same sink. Reading are 109 PPM. Tested water from a Coway filter and almost zero PPM. Is 109 fit to drink? Probably scrap the Pure filter.

Depends what's in it. Try testing water from a Singha bottle and a Nestle PureLife. Just a small bottle of each will do.

The Singha is distilled I believe and Nestle has minerals and compare them to the tap - been years since I tested the water though.

Singha vs Nestle should give you a good baseline for what's normal even though they will be very different

What’s important is that your filter removes things like. Chlorine, heavy metals and bacteria. The fact it doesn’t change the ppm is probably a good thing as it’s not removing essential body minerals

PPM ... is that something like T ... D ... S meter reading

We ditched out Pure filter after testing and went to RO delivered for drinking & cooking. As stated, depends what the particles are. Our only concern is heavy metals.

Use our Xiaomi T ... D ... S pen (inexpensive from LAZ) when O&A if free water is provided on the table and most actually do use RO bottled water 👍👍

Richard Barrow did test 7 different bottled waters from 7-11 and all were <10 pmm, with exception of mineral waters of course. That page no longer available on internet, just a snapshot on X
