Worst I've seen is 1500ppm!!! Yes, really. Private supply to a farm house. It's only used outside now but up till a few years ago it was their only supply!

The TDS meter reads 150 & a little x10 in the corner!

In large amounts then maybe.
But I'm sure it was much more expensive for a 5L bag I bought

547 is the higher end of what mine comes out at tap, not happy about that, normally 470/480

when with 10 inch filter I changed every month cost £3.50 for both, changed to 20 inch about £30 for 2 not changing for 10 months and see what happens, I may go back to 10 inch filters as 20 seem a rip off price.
