Water is most of the cup; in hard water areas a simple filter is one of the cheapest genuine quality upgrades, see best water for tea.

Why hard water dulls tea

High mineral content and alkalinity flatten aroma and can scum the surface; filtering reduces that, see water TDS.

Why too soft is also wrong

Distilled or very soft water tastes flat; some minerals help, so the goal is moderate, not zero, see water pH.

Who benefits most

People in hard water areas, especially drinking delicate or fine tea, get the clearest improvement; the main case.

Who benefits least

Already good soft/medium tap water; a filter then changes little, do not over spend.

What you do not need

Elaborate "tea water" systems or bottled water for everyday tea; a basic jug filter gets most of the benefit.

Quick take

In hard water areas a basic filter is a cheap, real upgrade; elsewhere it matters less, and you do not need anything fancy, see best water for tea.

The essentials: water filter for tea

Aspect	Answer
The answer	Worth it if hard-water region with delicate teas; not essential for most
Why hard water dulls	High mineral content binds tea polyphenols; reduces flavour clarity
Why too soft is wrong	Distilled water produces flat hollow tea; minerals needed for flavour
Who benefits most	London/SE England (hard water) drinking green/white/oolong tea
Who benefits least	Scotland/Wales/north (soft water already); primarily black tea drinkers
Brita-style jug filter	Good entry-level; reduces hardness modestly; £20-30 + filter cartridges
Bottled spring water alternative	Volvic (60 ppm) excellent for delicate tea; modest cost for premium tea
What you don't need	Reverse osmosis (removes too much), expensive multi-stage filters, alkaline water
UK water variation	Soft (Scotland) - medium (Manchester) - hard (London) - very hard (Cambridge)
Tea drinkers in London	Substantial benefit from filtering or bottled water for premium tea
Cost-benefit consideration	£3-5 weekly cartridges; £1-2 per litre bottled water; pick what works
Framing	Genuinely helps in hard-water areas; not essential for soft-water residents
