We have a plumbed-in water filter at work, but the person responsible
for changing the cartridge says he's stopped bothering because the
water continues to flow. He argues that, if the filter were failing
to work properly, the flow would diminish or cease. For my part I
think the water has stopped tasting very nice.

It's a Bayhall Filtamate if that helps.

Thanks

In addition to this, what's the score with those screw-on types that sit
under the kitchen sinks, which look a bit like a car's oil filter? I stopped
changing ours ages ago. I could never really be sure that it was actually
doing anything - when I first replaced it, it didn't seem very 'wet'
anyway - and I figured that as it protects everything apart from the kitchen
sink (and washing machine for that), that if it was contaminating anything,
it would only be the bathroom, boiler and toilet.
