How often should I change it?
Every 2 months.
| Your water | Change it | Who says so |
|---|---|---|
| Soft, Moderate or hard | every 2 months | Philips does |
| Very hard | every 6 weeks | We do |
The manufacturer gives a limit like "2 months or a set number of litres, whichever comes first". That is a maximum, not a target — so we never tell you to leave one in for longer, however soft your water is. Hard water uses up the softening part of the filter faster, which is why we suggest changing it sooner in very hard areas. That shorter figure is our suggestion, not the manufacturer's.
Not sure how hard your water is? Your water company publishes it on their website, usually under "water quality" and searchable by postcode.
