Product Description

Replacement In line Water Filter Cartridge - Female Connectors

Top quality taste and odour in line water filter using Granular Activated Carbon technology to remove contaminants such as chlorine.

 in line water filter replacement

This can replace your existing in line water filter for any make, in your house, office or for a commercial application such as vending machines.

Fitting Your New Unit

This should be very easy. All you do basically is take the tubing out of your old filter and feed it through the compression nut fittings supplied into your new filter.

Full and easy fitting instructions are supplied.

More About The Female Connector

The female connection type is where the tube fits directly into the filter.

Our female connection filters are designed to fit plastic water tubes a quarter inch ie 6.4 mm outside diameter.

 This is the size of the great majority of plastic tubing for water filters.

However if your tube size is different, no problem. We can supply adaptors. Simply let us know either before or after you order.

If you are not sure of your tube size you can simply order the filter now. We will help you sort out the adapters later. They will still be free. We'll send them out immediately. It really is very simple.

If you need tube adaptors, they usually cost £4.


Please note you only need to get the tube adapters ONCE.

Need Anti-Scale?
This filter is great for removing chlorine and other contaminants, giving you fresh, great tasting water. If you also want your new filter to be anti-scale please click here
Warning; it's more expensive so if you're not too worried about scale - ie the hard white stuff you see in your kettle then just stick with this filter. (Scale isn't "bad" for you. It's only bad for your kettle and sometimes causes the film you see on your tea / coffee.


Changing Your Filter

Your filter cartridge will need changing every 6 months.

The price of replacement cartridges varies depending on sales and so on. We guarantee you will get a special "customer loyalty rate" of at least the price you pay today.

Technical Information


What Your Filter Removes

Gets rid of the harmful contaminants that may be in your tap water such as:

  • Chlorine
  • 99%
  • THMs (trihalomethanes) ECBs, OCBs, TMEs
  • 90% to 99%
  • Pesticides
  • 90% to 99%
  • Herbicides
  • 90% to 99%
  • Industrial Solvents (halogenated hydrocarbons) PCBs (polychlorinated biphenyls) PAHs (polycyclic hydrocarbons)
  • 90% to 99%
  • Discolouration
  • 95% plus
  • Rust Particles, Silt, Algae
  • 99%
  • Benzene, Petroleum Solvents, Oil Residues
  • 85%


Need to remove more contaminants?

This is a great filter and usually does what most people in the UK need.

However, if you want to remove a specific contaminant, and cannot see it in the table above - for example fluoride, hormones, heavy metals, and so on - then you probably need a Reverse Osmosis unit.

But please note that good quality Reverse Osmosis filters are expensive and are ofter "overkill" for what most UK customers need.

Usually all you need for filtering UK tap water is to remove chlorine, like this filter above does perfectly well. Then you've basically got bottle water quality!

Simply let us know either before or after you order.  If you want to sort out the adapters later please rest assured that we'll send them out immediately. It really is very simple. Simply give us a quick call on 0800 009 6611 or contact us - either now or after you order.

(If you are replacing another filter then it will almost certainly have the correct tube size ie 1/4 inch (6.4mm) outside diameter... . But don't worry: If your tube size is different just let us know what it is and we can send you an adapter - either before or after you buy the filter)

Why your existing brand can be swapped with our one

Regardless of the brand name on your filter these inline water filters are all filled with the same media - Granular Activated Carbon. This does a great job at removing chlorine and other contaminants from your tap water.

The FLN2000 is our own-brand, high quality generic replacement for these water filters.

All you need to worry about is that your in/out tubing will fit your new filter. We are very confident this won't be an issue because all these filters accept the standard size 1/4 inch tubing (1/4" or 6.4mm outside diameter ie edge to edge).

If you're not sure simply give us a quick call. We can send you any required adapters free of charge - but rest assured this hasn't happened in a month of Sundays - as Granny used to say.

Don't worry there is a full Money Back Guarantee if you're not delighted with your new filter.

Ratings & reviews

Impressive - Review by Lissandro
Ordered a filter for my tap. It arrived super quick and well packaged. Installation instruction were simple and easy to follow and I have never touched any pipes in my life before! So well chuffed with that. When I had a concern, I sent UK-water-filters an email and I must say I was very impressed with their prompt reply. I am extremely happy with the filter and the service and have already recommended to friends and family. Overall, I am a happy customer. Thanks once again
Great service - Review by Lee Carter

Absolutely nothing is too much trouble for this company!
Customer service excellent from beginning to end of conversation and transaction.
Product excellent, have purchased these in line filters for years now and not only is the filtered water great to drink, all utensils have no sign of damage caused by tap water!
Many larger companies could learn from this company as to how to look after and keep their customers.

This firm keep a database containing your filter details and advise when renewal is recommended. At such time you decide to order they have all the details available to ensure that the correct filter is supplied. Excellent service and reasonable pricing.
Nice Product - Review by Keith Simmons
Nice product which is easy to fit and gives nice pure water. Customer service is also first class.
Filters Arrived Promptly - Review by Margaret Cook
My new filters arrived very promptly, but as usual I was having the utmost difficulty removing the old filter, I contacted this company about it and they suggested changing the connectors, I said yes o.k. they put new connectors in the post for me straight way along with the full instructions for fitting and I was able to change my filter straight away and very easily.
Excellent - Review by Anthony
Excellent value backed up by excellent delivery and helpful advice when I needed it. My email requesting advice on removing my old filter and replacing by one with different connectors received a rapid response and detailed instructions, followed up by free connectors by post within a day or two. My future filters will come from this supplier.

Much Easier - Review by Anthony Nickalls
Much easier than for having jug refill
Filters and service are excellent - Review by Rob
Filters and service are excellent thanks. Have already rung your office to say this. Have also responded to request for suggestions. Many thanks.
First class product - Review by Leolaw
At this price these filters are excellent value and have been found to be reliable. The female fitting makes connection easy and have no qualms in recommending.

Product and customer service excellent. Even send you reminders
5 star rating from me. - Review by Peter Vile
Always good service and back up. Deliveries arrive


Very helpful during telephone conversations.

What more can you ask! - Review by Edward Jones
I have used UK water filters for the last 2or 3 years after my previous source of supply ended. They supply good quality products, not the cheap "near enough" filters offered by some other firms. They are efficient, delivery is prompt and prices fair, they check after delivery that things are ok and follow up with reminders when replacements are needed.

Very cost-effective filter. - Review by Dr Stephen Worrall
A truly excellent and professional company. Online chat facility enabled me to find the correct replacement for my narrowboat filter system. Next day deliveryInstallation was very simple and straightforward.
Highly recommended
Friendly contact, and a pleasure to do business with. - Review by Les Bessant
I've been buying replacement filters for my kitchen filter tap from UK Water Filters for several years now.

Delivery is quick and the price is fair.

They helpfully send a reminder email six months after a previous purchase, and a follow-up message to check that there were no problems with the replacement filter.

Yes, I would recommend this company. - Review by Colin Bewick
We have been a customer for approximately 2 years. We live in a very hard water area and always suffered from "flavoured" water and limescale in our kettle. Since using UK Water Filters we have a contuous supply of crisp clear water with absolutely no scaling in the kettle.

The service is always prompt and efficient (the reminders are particularly helpful).
The prices are very good.
The product performs as expected.

excellent - Review by G Johnson
Excellant service at all times, will carry on using it

A very competent company. - Review by Alan Brant
I receive an email from them when my filter is due to be changed. The delivery is prompt and I have never had any reason to complain about the quality of their products.

top quality water filter - Review by Greg
Great service and quick delivery of a top quality water filter. This filter is inexpensive and makes to water taste much better than others I've tried. I love the email reminders, too. Highly recommended.
Superb. - Review by Di
I have used UK Water Filters for several years....saving lots of money on filtering by jug. My tap water without a filter is horrible , cannot get a decent cup of coffee. The filters do a great job. They are easy to fit and to change. The UK Water Filters after sales service is brilliant , reminding of time to change and then getting the filter to you rapidly.
filters work perfectly - Review by Keith
I have been using UK Water Filters to supply two types of filter for a good few years, I will not go elsewhere as their service is first class, the filters work perfectly and their prices are great. What else could I want.
very good service - Review by Donald
We have had very good service, receiving our order within 48 hours. Also useful reminders as it's easy to forget when a renewal is due.

very easy to install - Review by Gordon
I fitted the In Line Undersink Filter this morning. I couldn't believe how easy it was compared with the problems I had with the earlier filter. Mind you at my age getting under the sink is something of a trial but nonetheless this new connection is a dream. Should have gone for it ages ago.
good - Review by Simon
Can not give a 5 for 'value' as we always want things cheaper.
Positive response when my filters were late arriving, postal issue not UK Water Filters.
Follow up phone call and confirmation email from UK Filters followed.
First class service, great company - Review by Water Filters
Very easy company to deal with. The product they sell you is first class and the prices are more than reasonable. They remind me when it is time to change my filter and then ship it quickly. There are no negatives in dealing with them!
arrived promptly - Review by John
Filters received very promptly and one is fitted and working perfectly.
I cannot offer any tips - you send good instructions. So thank you!
Great Service and Price! - Review by Martyn Hamer
Found the staff very helpfull and courteous , price was great too, first class all round, Thank you again.

Easy to Fix Efficient to Use = Great Value - Review by zojo
For more than ten years this type of cartridge (FLN 2000) from UK Water Filters has provided great clear water on tap. Easy to install and remarkably trouble free in use. This company will be used again...and again...and again.
Excellent product - Review by Simon
Easy to install & replace, nice quality filter
Tidy unit does a great job. - Review by mscnoe
I have tried filters from the diy suppliers and none are as good as these for a clean, clear glass of water. The reminder service is great when you lead a busy life and the follow up "have you fitted it yet" reminder even better! Great product, good price, excellent service - what more can you ask?
Water Filter - Review by John DA
All good. A very good filter at a reasonable price and easier to fit than my last one. I stumbled across this supplier on the internet and am very happy with the quick response and their easy-to-use website. And if you have any problems they provide advice and support by phone. Highly recommend.

Superb service - Review by IanR
We installed a Britta tap a few years ago to deliver filtered water but the cartridges were very expensive indeed (£30 every 3 months). Then we discovered these filters at £15 ish every six months. Not only do they do the same job its almost 4 times cheaper! Couple that with fast service, helpful answers to any questions about the filter or fitting it (Britta don't do that) and reminders when its due for a change. That is why we have stayed with this company for several years now. Well done UK Water Filters!
A Simple Solution to an enduring problem - Review by woody
These on line filters certainly make our water taste better. We have a lead service and high pressure.
We are glad of these filters.
Good product, great value, excellent support. - Review by Banjo
All good. A very good filter at a reasonable price and much easier to fit than my last one, especially since UK Water Filters send you a new easy-to-fit kit with the new filter. And if you have any problems they provide advice and support by phone. Highly recommend.
Excelent product and helpful service. - Review by Phil Summers
I have used UK water filters for some years now. Having realised that I don't need expensive filters which allow me to fill my motorhome from a river or pool !
The product works very well, is easy to fit, and the service is excellent.

Exactly what I need.

Phil Summers
Reliable service - Review by Mike
I have been using water filters from UK Water Filters for about four years , I have found it to be a very good product a reasonable price and easy to fit the replacement . The back up of reminder when the filter needs to be changed and help over the phone if needed very good .
Great price - Review by Doreen
the water filter arrived safe and sound and in quick time as usual many thanks we are very pleased with it and what a great price.
Good value and super service - Review by IanR
Its now a few years I've been having water filters from Ed and his team. Always helpful, a mine of helpful advice, very fast service and delivery.
And - really nice timely reminders to get it fitted after delivery (I'm very forgetful so they help)
Thank you
Excellent Service - Review by Biomac
A quality product with instructions that are easy to follow and a friendly practical back-up service. The price is competitive and I always get a timely reminder and follow up to ensure customer satisfaction. An excellent service in every way
How easy was that! - Review by Graham
First time I've used these filters and I'm very impressed at how easy they are to install. After years of struggling to get push-fit connectors to 'let go' of teh old filter I love the simplicity of sliding the pipe into the filter and tightening up the nuts. Love the friendliness of the customer service e-mails as well.
Quick and good advice - Review by Stuey
Very friendly and know their stuff. Saved me a good amount of cash buying a none branded model which is just as good. Will certainly use again!!!
Excellent service - Review by David
The filters arrived promptly, I fitted one right away, & am very pleased.

Previously my system had used pushfit connections, but yours were even easier to install.

Very easy to fit and effective. - Review by Westie
This firm came to light as a previous supplier was difficult to order from and the collet connections were a menace as the spoilt the ends of the plastic pipes by digging in. Recommend this product as they always send reminders when filter is due for a change.
Good service - Review by Kat3_17
Arrived in good time, right fitting, seems to have improved taste of water from previous filter. Thank you
Highly recommended - Review by Greg T
This product really does make our water taste better, unlike a product I got elsewhere. Thanks to Ed for the advice and assurances. I will be buying from here in future!
Filter - Review by Jinglpete

Brilliant! - Review by Jacs
Delivery is very quick (and free!), the product is easy to install and never fails.

Would defintely recomment UK WaterFilters.

Excellent Product - Review by Dave the Clockman
A real bonus finding uk-water-filters, as everybody else seems to have stopped supplying this type of filter.Easy to fit and a top product at a very reasonable price.
Water Filters - Review by Keith Coghill
I have been a customer for about 5 years now, I am very busy and can easily forget to order a new filter. Edward regularly saves me the embarrassment by reminding me every 6 months. Its a quick delivery and a great service.
Water Filters - Review by Andrea
Been buying from U.K Water filters for a couple of years now, very easy to order, and very quick delivery.
Good Company to Deal With - Review by nicklug
I have used these filters for a number of years now, they are totally reliable. The company always send them mega quick, then they always back up their service by emailing you to make sure you have received your filter, and make sure its ok. The other great service they do is to email you to let you know its time to replace your filter, which is a great service because you change your filter twice a year, so its easy to forget, I would recommend this company to anyone.
Easy to fit, great drinking water - Review by Alex
Best piece of kitchen equipment, saves on jugs and loose filters, fit and forget taste free and odour free water on tap.
Excellent product and service - Review by Pete
This is our 3rd water filter. Received a reminder when the filter required replacement which is very helpful, as I can never remember. Ordering and delivery always first class.
Universal filter - Review by Martingg
Good value fast delivery easy to fit
Excellent response time - Review by YK
We have received our order, posted to us here in the Channel Islands, just 5 days after we placed the order and that included a week-end. Now that's what I call excellent response time.
Thanks you very much.
Great service - Review by AVC
Thank you very much the water filter & tap arrived quickly and are now fitted and up and running.

As usual, I am very pleased with the items, service and delivery.

Long may your company prosper.
Water filter replacement - Review by Kathy
For the first time I decided that I could replace the water filter myself, but couldn't get an exact replacement to the filter I had. I made a call to UK water filters... Didn't leave a message cos they were closed, but they returned my missed call!! How good was that?
Anyway, I was advised re replacement and the filters arrived within 2 days. The quality of the water is noticeably better than the tap water, even though we have very good drinkable water. Well done for outstanding service, and good value filters.
great service - Review by khalaria

Purchase of water filters - Review by Olly
I have used UK Water Filters for many years now and they are an excellent company. The filters come really quickly and I have never had any problems with them.

An excellent Company to deal with
Nice product and easy to fit - Review by Howardc
Once I'd found the isolating screw under the sink this took all of 2 mins to fit. Instructions are clear, product seems good quality and it arrived very quickly. Means I can throw away my Brita filter jug!

The only criticism is that it's impossible to find a pen that works so that you can write the installation date on the side of the filter. So I used a Post It instead!
Great service - Review by Debs
Just to let you know the water filters (posted yesterday) have arrived today, so many thanks for that. Still know sign of the others though. I’ve checked with the other offices in this building and no-one’s taken delivery by mistake. As I said before, if the original does turn up (unlikely though it seems with our great Royal Mail!), I’ll send it straight back.Many thanks for the fantastic service once again. I’ve already recommended a friend following the great service and will continue to do so.Have a good weekend.Best Regards Debbie D
