One of the most popular undersink boiler/chiller units available, the ISE Insinkerators are very popular throughout Western Europe. The F701R fits the HC1100 and the GN1100 systems - Some unscrupulous vendors may try and sell AP3-C765 filters from 3M as 'compatible' however, these do not properly fit and then customers often find their boiler requires a head change.
So, we designed the FilterLogic replacement - The first genuine like for like replacement for Insinkerator which still affords your appliance the same high level of protection against limescale BUT at a fraction of the cost of the OEM replacement from ISE. FilterLogic products feature a high quality sintered carbon core, with food-grade polyphosphate to prevent damage being caused to your boiler by scale forming minerals.
This product can also be used to replace other AP3 series cartridges from 3M for other applications.
This filter should be replaced every six months.
