How Long Does it last For?
*This filter should Last at least 6 months in 95% of UK Water Areas
Dependent on your local water chemistry.
It can be hard for us to be completely sure that this filter will stop scale for the entire 6 months - due to there being thousands of local water treatment plants in the UK, each with it's own a unique water chemistry - which can change regularly. (Even within the same area and postcode the water source can be different).
However, please rest assured that the cartridges do work well for the full 6 months for at least 95% of our customers.
You will know the filter's worn out when you see film on your tea and coffee or start tasting chlorine - or it's past 6 months whichever is the sooner.
If you're in a particularly bad scale area the flow rate can make a big difference to how long the anti-scale element of your filter lasts. The slower the better.
We'll send you a free flow rate regulator shut off valve to alllow you to adjust the flow rate of water through the filter into the tank.
How to Swap this New Filter with Your Insinkerator Original?
This is easy.
You simply swap out the old Insinkerator filter with our new one.
All this involves is removing the in/out tubes and inserting them into this compatible cartridge.
Apart from that simply follow the original change instructions eg turning off the power supply and flushing the filter through etc.

Original Filter
Easy replacement
"The filters which I purchased were advertised as perfect replacement for the ones that I had been using. It was true....the filters which I ordered do fit and do the job 100%. I will definitely be reordering these again!"Chris Coupe

This shows an installation for a Proboil - but it's the same principle!
Free Tube Adapters?
Your original Insinkerator F701R cartridge has 3/8 tubing (9.6mm).
Like most water filters our compatible filter uses 1/4 inch tubing
But don't worry. We include a free tube adapter in your kit.
It takes seconds to setup. And you only need them once.
The filtration material inside both filters is basically the same.
And we'll send you a free Mounting Bracket to fit your new filter.
Not in a Hard Water Area?
If you are not in a hard water / limescale area then save yourself money by getting this standard inline filter.
However if you are in a very hard water area and want to better protect your hot tap / water tank then consider this more powerful anti-scale filter.
It will also connect to your existing Insinkerator tank - but, if you choose that option, ask us for the free tube adapters (form 3/8th to our standard 1/4 inch tubing).
Does it Void Your Warranty?
Insinkerator and other boiling tap companies might say they will only warrant the original filter type supplied and claim it is "formulated specifically for their product"
... and that If you change it for an alternative filter it may have a "detrimental effect" to the system so will invalidate your warranty.
Well you do need an anti scale filter to prevent scale build up in your boiler (like you would for a kettle).
So, as far as that's concerned, any attempts to get you to keep using their filter would be fair enough.
But claiming a different filter will damage the unit is arguably like saying that using a different lightbulb to the one supplied will damage the light.
How can we put this any more politely?
Conclusion: The filter will NOT damage your boiling tap. But the manufacturer might use it as a reason to void your warranty.
Don't worry!
Although many customers have bought these alternatives and are perfectly happy with them, please don't worry. It's all on a Full Money Back Guarantee basis.
If you don't like it for any reason you can send it back!
Will it Affect Your Scale Reading?
No it won't affect your scale monitor / read-out. This will work in the same way as before.
Will it Affect Your Filter Warning Light?
It shouldn't do! That light is almost certainly set on a simple timer.
Just reset the light in the usual way.
Free Wall Mounting Clip
We'll include a wall mounting clip with your order - for free.
You can use this to mount the filter neatly in your cupboard.
You'll only need to fit thisonce - they're easy and convenient.
(The clip is optional. Simply add it from the screen pop up at the checkout stage.)

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.

“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!
