Review: So far so good - good instructions to install, water much improved, stylish tap - No issues so far. Installation took me a while but that is mainly because I am not used to this sort of job and it took me a while to figure out the best place to put everything Instructions were clear and everything provided. Really pleased with the taste of the water and the functionality of the system. Would recommend
Review: Epic bit of kit - Could not be happier. Polluted water source got a TDS reading of 24 ppm from raw. Would highly recommend a prefilter system to protect the unit though. Not designed to handle off grid living but does an excellent job

## Questions & Answers

**Q: is the water alkaline from this system**
A: Yes, the remineralisation filter makes it alkaline

**Q: Seems replacement filter are not easily available in uk, amazon have only the asr211 but it’s £100! is that right?**

Kind regards,
Frizzlife customer service

**Q: How noisy is the machine?  Watch one on youtube - it sounds really noisy but not sure if it was the machine or how it was recorded.  Thanks**
A: i am using 1000gpd, don't know 600gpd
i think the machine assume u install under the sink, then will not feel noise
i dont't know where u live, if live in house, i think it's ok
i live in 1Room, the machine flush every 6hr, so i power off when sleeping, which can wake me up

since my usage is too low, i sw on in morning then it flush, then i open the tap 30s but not use it, 
because the water coming out is soaked over 23hr, u can see the ppm is very high, 
after 30s the ppm become normal, then i use it, if u have no tester then remember 30s, i tried 20s, but the ppm still high (over 1xx ppm)
and use a big glass bottle to store the water i need to use, then i sw off the machine
may be i am too sensitive, i can smell if using plastic bottle

**Q: For those who have purchased the RO without the remineralisation filter, how do you find the taste, what method have you used to replace lost minerals**
A: feel sweet

i already get all minerals from meal fruit,... not from water, since which is very less in water, because u can taste it when water ppm is high, and don't want to drink that water

Could not be happier. Polluted water source got a TDS reading of 24 ppm from raw. Would highly recommend a prefilter system to protect the unit though. Not designed to handle off grid living but does an excellent job

### ⭐⭐⭐⭐ RO Water filter
*by U***N on 15 December 2023*

Water tasted excellent first 4-5 weeks. But after 5 weeks or so we started noticing change in water taste and some lame scale started appearing in the kettle 😞
