Filtr8 Replacement Water Filter Cartridge
The genuine replacement cartridge for your Filtr8 Under Sink Water Filter. Removes up to 99% of lead, chlorine and microplastics, so your water keeps tasting the way it should.
What it removes
What Filtr8 takes out of your water
Tap water can carry things you'd rather not have in your glass. Filtr8 removes up to 99% of these four.
Lead
Older homes can still have lead pipework, and traces of it can end up in your water.
Chlorine
The main cause of that swimming-pool taste and smell in tap water.
Chloramine
A longer-lasting disinfectant some water companies use instead of chlorine. It can leave a taste of its own.
Microplastics
Tiny plastic particles, caught by a carbon block with pores just 0.5 microns wide.
Compatibility
Fits every Filtr8 kit
One cartridge type, whichever kit you have.
The proof
Tested. Read the results yourself.
