## Description

Waterdrop WD-KJF Filter, Replacement for WD-KJ600/WD-K6 Reverse Osmosis Instant Hot Water Dispenser System : desertcart.co.uk: DIY & Tools

Review: RO water filter, TDS now 30-40 TDS - RO water filter, TDS now 30-40 TDS. Instant hot water is a bonus uses ~ 16kw per month for hot water & for tea & cooking & RO filtering. Kettle is now in storage Water tastes far better plus coffee in bean to cup machine tastes far better now too.
Review: Useless. - What is the point of an extra filter when the main unit died just after operating for a month and a half. Don't bother buying this with your system unless your unit has in fact lasted longer than an year. And if you are in the UK there is no warranty here. The offices are in China with a US office so if you get a persistent E6 or E5 error they will not send out anyone with parts to fix this. Just save your money and shop somewhere else something else.
