## Questions & Answers

**Q: My insinkerator came with a model f 201 r filter which now needs replacing, is the f 701r compatible ?**
A: I have used this product without ant problems but be careful of your warranty as I repair agent does not allow non recommended items and would void your guarantee on the boiler

**Q: Is this fit to hc1100?**
A: As far as I can see the HC1100 uses the F701R cartridge and this is compatible with that cartridge. I have been using them for quite a while now and they work superbly in my Insinkerator system.

**Q: Will it fit gn1100**
A: Sorry, I have no idea what a gn1100 is.

**Q: how long does the filter need to be submerged in water in order to de-aerate it before fitting?**
A: Thank you for your question, for a couple of minute. You will see the air bubbles emerge from the filter. Please shake the filter a little and when a couple of minutes has passed and not more bubbles come through, please install the filter. Kind regards, Finerfilters Ltd.

### ⭐⭐⭐⭐ Good value product
*by G***N on 20 January 2018*

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
