Mains Water Filters

 

Enjoy filtered water in your house with our mains water filter systems or whole-house water filters in your home today.

Made in the UK

Fountain Filters are a leading UK supplier of home water filter systems. 

Water filter systems for home use are often referred to as a mains water filter or whole house water filter. This simply means that the water filtration system is fitted to the rising main where water enters your house.

A home water filtration system is a plumbed in water filter that will provide you with fresh filtered water from your kitchen cold water tap and at other taps throughout your house should you want it, such as your bathroom or utility room.

If you are looking for a water filter system where your filtered water is dispensed through a separate drinking water filter tap or 3 way tap, then please look at our range of drinking water filters.

As UK water filtration experts, if you are unsure which of our home water filters is going to be right for you, then please call us on 01352 838 281 or send us a message via our helpdesk.

What is a mains water filter?

Mains water filters and whole house water filters are plumbed in to the rising main where water enters your house. They provide your household with filtered water in your kitchen and at other taps throughout your house should you want it; for example your bathroom or utility room.

Our whole house water filters are suitable for mains water supplies only. If you have a private water supply, your requirements will be different so please take a look at our Private Water filters page.

If you are unsure about what mains water filter you need and would like some advice, please call us on 01352 838 281 or send a message.

Which type, and size of home water filter system should I choose?

Any domestic water filtration system needs to be large enough to cope with the demands placed upon it. 

If it’s too small, you’ll be very disappointed with the flow rate and pressure of your water. 

Mains water filters operate at mains pressure and flow rate, as opposed to drinking water filters that run at no more than 4 l/pm. 

A water filter system that treats your kitchen cold water tap only, such as our cold water tap filter Moby will be a smaller unit (H 38cm x W 30cm x D 18cm ) than a whole house water filtration system.

Whole house water filter systems are plumbed into your cold water supply just after the stop cock. The Doby is a good example of a larger (H 72cm W 30cm and D 18cm ) whole house system.

If your home has an 'open water system' (header tank and immersion heater) then one or more cold water filters from our Moby range will be the most beneficial or efficient to install.

We recommend a Doby whole house water filter if you have a 'closed water system' (no header tank or immersion heater).

How will your home benefit from a mains water filter system?

Your home will benefit from a domestic water filter system in so many ways.

  • You get clean filtered water that tastes and smells better from every tap in your home without the need to install separate taps.
  • You can tailor your water filtration system to resolve the issues you have with your water. This means that you are in control over what's in your water and what isn't.
  • If you have hard water and opt to install a hard water filter system in your home, you'll extend the life of your household appliances, and protect your home's plumbing system.
  • You'll waste less money on buying water in single use plastic bottles.
  • Your entire household will benefit from the cleanest, safest water you can get.

FAQ

How often do I need to change the cartridge in my mains water filter?

You'll normally need to replace the water filter cartridge every 6-12 months depending on how much water is being used in your house. We send out email reminders every six months as a prompt for your to check the performance of your mains water filter.

Can I take my mains water filter with me if I move house?

Yes. Just take out the housing and join the two flexi's together with a 1/2" bsp nipple. When you get to your new house just purchase two new flexis and re-install your housing. It really is that easy.

Do I have to install a mains water filter under my sink?

No, you don't. You can install your mains water filter wherever the cold water supply enters your house. This could be a utility room, garage, or other location.

Is a water filter cheaper than buying bottled water?

Once you've purchased your intial water filter system the ongoing running costs are cheaper than buying bottled water. 

What is the average cost of a whole home water filtration system?

You can buy a whole home water filtration system for under £150. The price of our water filter systems varies depending on what you want to change about your water. 

* Watts components are sometimes replaced with other similar quality items due to supply chain issues. Brassware and other plumbing accessories are sourced from UK suppliers.

Great 3-way tap

Great 3-way tap, which was well packaged, with clear instructions. Our plumber commended the tap as good quality and easy to plumb in and connect to both water supply and under-sink filter. Looks brilliant in our new kitchen. Thanks to Fountain Filters for a helpful website and speedy delivery service.

Fintan Somers

It was a small but important order: replacement o-ring with silicon for my water filter housing. when I told them I had not received the articles after 7 days, they without fuss dispatched a replacement with the result I received the original and replacement 3 days later! Very responsive customer service.

Sonny Sethi

After moving into a property with a fresh water supply, I turned to Fountain Filters for advice on replacing the water filter system. I purchased the Moby Twin Sediment System and it has been a worry-free system. Even changing the filters was far easier than the old system. Cannot fault this company on speed of service or quality of advice.
