Introducing Best Inline Water Filter UK

Here they are:

1) Samsung DA29 10105J External Inline Fridge Water Filter

This is the most popular inline water filter on the market. It’s for Samsung fridges/fridge-freezers which have externally fitted cartridges.

Filter typeActivated Carbon
Flow rate1.9 L/min
Filter capacity1000 Gallons (3785L)
Operating pressure Min.25psi (172kPa)
Operating pressure Max.125psi (862kPa)
External testingNSF certified


  • The flow rate, at 1.9L/min, is more than what the vast majority of people would need. Your water will flow fast enough that you’re not getting bored standing there, waiting for the cup to fill up!
  • It’s a genuine Samsung filter, so you’ll have no worries about whether it will fit, and no quality issues.
  • Activated carbon is a high quality filter type. It uses a process called adsorption to remove contaminants, trapping them in the carbon filter media. The main benefit and usage is the removal of chlorine, so that your water is safer, healthier and no longer has an unpleasant taste.
  • The 1000 Gallon capacity is plentiful. It depends on your water usage and the condition of your water, but most people will find this filter will last them for a year and a half to two years, or thereabouts.


  • Perhaps some people would want a filter that lasts them several years, rather than just a couple. But this inline filter is as good as it gets.
  • It’s more expensive than some other filters on the market. You’re paying because it’s Samsung branded, and so it’s higher quality, longer lasting and will definitely fit.

2) Aquahouse AH-UIF (4 pack)

This is also a highly popular fridge inline water filter. It’s for Samsung, Daewoo, LG, GE, Beko, Rangemaster, Hotpoint, Bosch and Haier fridges. Specifically those with external water filter cartridges.

It’s for those with 6.35mm (1/4in) diameter supply pipe – that’s the dimensions for most refrigerators.

Filter typeActivated carbon
Flow rate1.9L/min
Capacity300 Gallons (1135L) / 6 months
Max pressure120psi
External testingWater Quality Association Gold Seal program (meets NSF/ANSI 42 and 372)


  • It works with almost any fridge that has a 6.35mm (1/4in.) supply pipe.
  • Flow rate is excellent, at 1.9L/min.
  • For a fridge filter, 300 Gallons is not bad – it should last you for several months, perhaps 6 months or more. Of course, that depends on how much water you use, and the severity of your water issues. Since this a 4 pack, you should be getting around 2 years of usage in total.


  • Changing the filter every 6 months may feel inconvenient to some people. Weigh up whether you’d prefer to pay a little more for the Samsung inline filter (at No.1 on our list), which is just one filter that can last up to 2 years. That would save you the inconvenience of changing it every 6 months.

What is an Inline Water Filter?

It’s a long and thin filter cartridge. It can be connected to a waterline on your home.

They can typically be connected anywhere from the Point of Entry of water into your home to under the sink in your kitchen, or to a fridge’s external filter cartridge.

The fridge cartridge is the most common, and our No.1 and No.2 inline water filters are both for fridges.

Why would I need an inline water filter?

It’s a simple, relatively inexpensive way of filtering your water, to make it healthier and safer.

Typically, you’d need one if your water has too many contaminants, most notably chlorine. Some people may even be able to taste chlorine or other chemicals.

An inline filter can solve this problem.

How does it compare to other filter types?

It doesn’t have the exceptional filtration capabilities for all types of possible harmful contaminants. For example, a reverse osmosis filter system is the better suited water filter to remove hormones, viruses/bacteria etc.

If your water has a chlorine taste or smell, then an inline filter will do an exceptional job of removing it. Or if there’s a high quantity of small contaminants like dust or dirt, then this filter will do a great job.

And an inline filter is very easy to set up and requires no maintenance, other than changing the filter every now and then.

FYI, here are the best water filters in the UK.

It’s not suitable for treating hard water. For that, you’ll need a water softener (here are the best of the UK’s water softeners.

How does it work?

The water pressure in your pipes pushes water through the inline water filter. As the water passes through the filter – or a series of filters – harmful contaminants are trapped, and the cleaned water passes through for you to drink.

Most filters of this type use activated carbon in their filters. Both the No.1 and No.2 of the best inline water filters (UK) in this article use it.

Activated carbon is one of the best filter types in the world (here are the top filters with activated carbon medium). It works by a process called adsorption. The tiny contaminant molecules are attracted to the solid activated carbon and are collected on its micropores. Thus they are removed from the liquid water as it passes through.

And so, with these impurities removed, you’re left with safer, cleaner, healthier water.
