Review: Reliable Under-Sink Water Filter That Improves Everyday Tap Water - This InSinkErator F-701R under-sink water filter has been a very practical addition to the kitchen. Once installed beneath the hot water tap, it noticeably improves the taste and clarity of the water straight from the tap, which means I’ve been using it for cooking and drinking far more often instead of bottled water. The 454-litre capacity lasts a good while before you need to change the cartridge, and having a 2-pack means you’re stocked up for future replacements without having to reorder straight away. Installation was straightforward if you’re comfortable with basic under-sink connections. The filter fits neatly into the space and doesn’t get in the way of other plumbing, and once in place it operates quietly and efficiently. Changing the cartridge when it’s due is simple too, which makes maintenance quite painless. It’s not the cheapest filter on the market, but the improvement in taste and overall water quality feels worth the price for everyday use. If you want cleaner, better-tasting hot tap water without the fuss of frequent refills or bottles, this does exactly what you need.
Review: Does the job. - Does the job it is made for. I have not had any problems with others I have used.

## Questions & Answers

**Q: Is this compatible with HC1100**
A: Yes, this is the appropriate Insinkerator filter for the HC1100

**Q: Does a used filter just increase the filtration process and just slows down the water flow. Surely no impurity’s should be getting through?**
A: These filters work well for my hot tap. After 6 months I notice both a change in flow and taste. So I would say from the taste change that it doesn't filter as efficiently. I change my every 6 months as per the manufacturers recommendations.

**Q: There was a lot of transparent gel or glue under the red cap. Is this normal and what's it for?**
A: I bought a twin pack from Amazon in Feb this year (2021) and not only did the filters have have the gel-like substance on the cap but they also had a few drops of water dripping out of them once the cap was removed. 
It’s outside of the Amazon returns window now so I contacted Insinkerator regarding this and they confirmed there shouldn’t be any gel or water present. 
Ordered a new set from Insinkerator on a subscription now via their website.

**Q: How do you no which filter to get**
A: Refer to the manufacturer’s model details.
