## Questions & Answers

**Q: Which filters does it use and how offer do they need to be changed? How many filters in total?**
A: It is a 5 stage filtering unit with 2 sediment filters, 2 actived carbon filters and 1 Reverse osmosis member. There is no remineralising filter though description talks about remineralising water from the filter. I haven’t had the system that long to have the cartridges changed So I am yet to see the compatible cartridges for this. drop a note to the seller and he should come back with the recommended one

**Q: How often the filters need replacing and how easy is to change filters?**
A: it all depends on your water hardness.. Manufacturer recommends they are replaced every 12 months or so - it's very easy to replace, lift the cover, unscrew them all one by one and follow the manual. 
I haven't replaced mine yet - but my input TDS reading is 380 - and output after manual flushing - 21. Without manual flushing - the reading is a bit higher - around 100 - but it's still almost 4x better than tap water.

**Q: Does this need to be plug in? How much time does it take to filter?**
A: Yes it needs to be plugged in so you’ll need a socket nearby. It’s an instant RO system and water flow is decent enough for a filter unit

**Q: Hi, can I have a link to purchase the correct replacement filters?**
A: Hello 
The link to the filters is
