Comparison between Fridge Filters, Jug Filters and Under Sink Water Filters

Fridge water filters

Advantages:

  • Water is passed through the filter and stored in a tank in the fridge which keeps the water chilled.
  • Certain fridges can also produce filtered ice, which uses the internal filter to clean the water before freezing.
  • Compatible versions of filters are available for genuine models.

Disadvantages:

  • Can only get a small variation of specifications for your particular fridge.
  • Can be expensive if genuine filters are purchased.
  • Some water filters will eat into the overall space available in your fridge. Some filters are located in the fridge door or located in the top corner, above the fridge shelf.
  • Flow rate from a fridge is usually a lot slower than usual tap pressure.
  • With the water being filtered, stored, and chilled within a tank in the fridge itself, it is possible for the fridge to run out of cold water if you are filling up a large container or making multiple drinks.
  • You are limited to the number of contaminants can be removed depending on fridge make and model and filters available to you.

A fridge water filter is a great starting point for anyone who has purchased a water dispensing fridge and looking to get into drinking filtered water. Even if your fridge doesn’t have an internal water filter and it is plumbed into the mains water, you can purchase a fridge fitting kit for a small cost (£16.99 on Finerfilters.co.uk) and purchase a separate external inline water filter to deliver filtered water to the storage tank.

Fridge water filters usually come directly installed with most new models of refrigerators. So, if you are looking for a new fridge as well, you can essentially get a 2 in 1 or even a 3 in 1 deal if your fridge makes ice. We recommend if possible having both a fridge and under-sink water filter. That way you are able to have both cold filtered water in the fridge and a higher specification filter for under your sink.

Jug water filters

Advantages:

  • A cheap initial investment, and cheap replacement cartridges.
  • Offer carbon-based and sometimes limescale inhibition media.
  • Can be put in the fridge to chill the water.

Disadvantages:

  • Cartridges usually have to be replaced every 30 to 60 days.
  • Jugs are gravity fed, so the filtration process is slower.
  • If the jug is placed in the fridge, it can take up a lot of space.
  • Limited to filtration capabilities. Usually, only carbon filtration and sometimes limescale inhibition is available.
  • Only a limited amount of water can be filtered at once, depending on the size of your jug. Most jugs have a capacity of 2-3 litres.

Water is poured into the top container and funnels down into the middle where the filter is located. Untreated water enters the top of the filter and gravity pulls it through the media and then dispensed out of the bottom into the bottom section of the jug, ready for pouring. Each filter usually has a lifespan of around 4 weeks/30 days.

Jug filters are still surprisingly popular, even with their slow filtration rates and limited capacity. Their appeal is that there is a low initial purchase cost and cheap replacement cartridges. However, our Aqua Quality Undersink Kit is better value for money. For £17.99 you receive a carbon water filter, tap and everything you need for installation. It does the same job as a jug filter, if not better, and the filter only needs to be changed every 6 months (for a minimum cost of £6.49)! On average, a jug filter usually costs between £10-£20 and includes 1x 1-month filter cartridge.

Under-sink water filter kits

Advantages:

  • Plumbed in filter system, offering filtered water on demand, whenever you want it.
  • Quick flow rates (up to 2lpm/3lpm in some systems).
  • Cold, mains water protection.
  • Takes up little to no space under the sink, or in the fridge.
  • Get the best of both worlds if you wish – have a filter which can provide quick flow and then fill up a jug and put it in the fridge.
  • A wide variety of filter specifications to suit your requirements. Able to remove contaminants such as bacteria, heavy metals, limescale, fluoride, etc…
  • Much more economical and helps save the planet by cutting out plastic pollution. A great alternative to purchasing plastic water bottles.
  • Undersink kits usually take no longer than 30 minutes to install.
  • Filters only need to be changed up to twice a year.

Disadvantages:

  • Undersink kits are not portable and need to be plumbed in
  • Not as cold as a jug that has been kept in the fridge.
  • Depending on the kit, initial costs may be higher.
  • All of our under-sink kits come with DIY instructions and can be installed by someone with an adequate level of DIY experience. However, if you are not confident installing it yourself you may need some assistance.

Undersink kits our one of our best-selling products for a reason. They are incredibly popular due to their convenience and economic benefit. If you are interested in seeing how much money you could save, head over to our cost saving calculator: https://finersystems.co.uk/cost-calculator/

An under-sink kit is essentially made up of 4 components: A filter (with mount/head), a tap, tubing, and an installation valve. They are not as daunting to install as you may think, as most kits can be installed in 10-15 minutes. Our staff are always happy to assist you in picking the right kit for your needs.
