"Absolutely outstanding service. These folks really do know how to do an amazing job. I honestly am so delighted with everything they have done. The kit is superb, water tastes wonderful. They always send the filters quickly and have answered many questions I had when fitting the system and the replacement filters. I highly recommend them.

Filter easily fitted, gives 6 months of crystal clear drinking water per filter cartridge. Water on tap, no messing around with filter jugs etc. Wholly reliable company. They even remind you when to change the cartridge. What more could you want.".Independent Review by "Oldguy"

Why so cheap?

We are sometimes asked, "if these filter systems are so good, why are they not more expensive?"

It's true that other retailers sell similar products at higher prices. While ours are certainly good, high-quality products we're happy to charge you less for a couple of reasons.

First, we only sell on the internet. Unlike other retailers, we don't have to pay for expensive shop rents and rates.

The second reason is that we have been in the water filters business for a long time and can source the best quality filters at the best prices.

We are very pleased with the filter and the service. Arrived without delay and easy to install, so it was up and working in very little time. I would recommend this product to anyone who likes good water, no need to buy bottled water any more".Independent Review by David


Your Running Costs

You need to replace the filter cartridge every 6 months to keep your water fresh and pure.

Replacement cartridges £15.95 cartridge (including postage / VAT etc) amounts to only £2.65 per month

What Type of Plastic is this Housing Made From?

These housing units are made of PolyPropylene (PP).

If you're concerned about plastics - we think you're right to be.

Plastics like BPA's (often found in food and water containers) and Phthalates (in PVC products etc) are linked to cancers, fertility problems, obesity, hormone / endocrine disruption and God knows what else.

The problem is they leach into the food or liquid they're holding.

However PolyPropolene (ie our housings) does not contain BPA's or Phthalates. and is thought to be much safer because it doesn't leach chemicals like some other plastics do.

PolyPropolene is one of the oldest and most commonly plastics with no known negative health effects after seventy years in widespread use (Sources: ESIS – European Chemical Substances Information - and the Hazardous Substance Data Bank (USA).


I'd like to say that I am very impressed not only with the product but with the back up service you provide". Independent Review by Max

    Such an improvement over unfiltered water. Losing microplastics, scale, chlorine and all the other nasties that can work their way in is just a bit of piece of mind for me in relation to my kids.
    – Nick Love
    I've had the filter installed for 1 month now and the water tastes loads better and no more smell of chemicals, just clean fresh filtered water I'd say it's the best water I've ever had.
    – Neil Bradfield
    “My filter fits easy and I am happy. We weigh the old filter when it is removed, filled with gunge which never got into our bodies with this filter. It’s quite frightening. My filter is worth every penny!
