Finerfilters FF-40 Water Filter Cartridge Compatible with InSinkErator F-701R and F-201R Hard Water Filter to fit ISE Instant Boiling Hot Tap Systems Using The Neo Tank with A1 or A3 Head (1 Pack)

Packaged well arrived on time and fits perfectly five stars

Great product at a reasonable price

Very disappointed , fits fine but flow through filter is very much lower than the original filter , we live in an area with extremely clean water so the filter has very little to do but brand new it flows about 1/3 the rate of a filter that had been on for 4 years However contacted makers and sorted it out ,product needs to be thoroughly de-areated before use .once done, the flow matches the OEM one ,failure to explain this in the instructions loses them a star

Does the job adequately.

Was unsure if it would fit, however, have just replaced the original filter. Fits perfect. At a fraction of the cost for an original can not fault it. My hot tap is a F-201R

Frequent use of this filter has kept my constant hot water tap in excellent working order...we've been ordering the filters for the past 5 years. Prompt delivery every time

This was bought because I was getting fed up with the cost of the genuine Insinkerator cartridges, and I have to say that it is a direct plug-in replacement and appears to work as well as the genuine article, but at a lot lower cost. I bought this as a single cartridge to try it out, but in future I will by the multipacks and save even more.

Fitted perfectly, works fine. Time will tell if it is an improvement on the manufacturers own brand.
