Introduction
If your fridge dispenses filtered water or ice, the filter inside needs replacing regularly — usually every 6 months.
In the UK, the most common issue is finding the correct replacement for your fridge model without accidentally buying:
- US-only filters
- Incompatible generics
- Overpriced imports
This guide shows UK-verified fridge water filter replacements for Samsung, LG and Bosch, explains how often to replace them, and helps you choose between genuine vs compatible filters. If you are comparing options and tap vs fridge water filters, then please see my guide here.
This article focuses only on replacements, not fridge reviews — so there’s no overlap with pitchers, RO systems, or tap filters. For renter-friendly water filters please see our guide here.
HOW FRIDGE WATER FILTERS WORK
Most fridge filters use activated carbon to reduce:
- chlorine & taste
- odours
- sediment
- some heavy metals
They do not soften water and do not remove fluoride fully.
If you’re unsure what’s actually in your water, start here. If your test shows high TDS or contaminants, these are the best reverse osmosis systems in the UK for maximum purification. If taste is the only issue, see my guide on the best tap water taste filters UK. For targeted contaminant removal, here are the best fluoride water filters UK.

WHEN SHOULD YOU REPLACE A FRIDGE WATER FILTER?
Replace immediately if you notice:
- slower water flow
- bad taste or smell
- cloudy ice
- filter older than 6 months
Even if water still “tastes fine”, exhausted carbon stops filtering properly. Fridge water filters should be replaced regularly, even if the water still tastes fine. Over time, saturated cartridges can reduce flow and allow bacteria to build up in cold, damp conditions. If you want to understand when to replace fridge filters and how fridge cartridges compare with other household water filters, this UK replacement guide breaks down recommended intervals by filter type.
