After 13 months, it’s asking me to change the filter. Wish, it had popped up over the week end. We will do the change tonight. The plan is : * sanitise * replace all the filters * flush out until the water is good The [manual](https://www.osmiowater.co.uk/manuals/Osmio_Zero-IP-II_Manual.pdf) suggests sanitisation on 2.5L water using 2 milton tablets. Once the sediment filters are in, it recommends 4 x 2.5L flush. @"DavecUK"#1, is this what you follow please ? Is there anything else do we need to do.

@"LMSC"#p11213 There is a video showing on osmios site how you can tip the unit up over the sink to empty the small internal storage tank for RO water. This will make flushing it out much easier. https://www.youtube.com/watch?v=w161FksKJEU&t=51s https://www.youtube.com/watch?v=j09bFxScfy4

@"DavecUK"#p11216 Yeah, I saw the first video before. Thanks Dave.

@"LMSC"#p11213 hi, I did this a couple months ago, your plan is correct and Dave’s video links are all you need. It will take a bit of time though, can’t remember how long now, maybe 3 hours after all flushes etc. also a quick guide to the specifics involved here from osmio site: One other thing I remember others had issues when they put more than 2.5L of water on during the sanitisation I think it leaked or overflowed

@"LMSC"#p11213 weird mine did the same today. bang on 12 months

Likewise - as if it were programmed😂

I think it kicks in automatically after a year. Makes sense too.

@"LMSC"#p11274 I believe it does kick in after 12 months, as the filters have to be changed at 1 year…Or if the Osmio senses the filtering is too slow, then it kicks in early assuming the filters are clogged, as in a high limescale area (sometimes this can be just the carbon block).

@"DavecUK"#p11276 Makes sense. It’s a good reminder to change after 1 year of use. The advantage of using the softened water in OZ is the readings are still very good indicating the filter is good for re-use. But, should change for hygiene reasons. Look at my readings, after the filter change popped up. > Our unit turned to change filter after 13 months. It still reads 58 TDS, KH is 31.25 mg/l and GH is 13.43 mg/l. Edit : We haven’t had time to change this today. Will do in the next few days.

@"DavecUK"#p11276 Am sanitising and changing the filters now. 1. The sanitising process suggests 4 x 2.5L water flush to remove the Milton solution from the unit (a) by leaving the existing blank filters at the back of the unit and (b) put only the new sediment filter in the pitcher. It then refers to changing all new filters. However, there is no mention of flushing out water once the new filters are in. I am thinking if we should flush out 2 x 5 L water out after resetting and replacing with new filters. The other choice is using step 1 and replace 1a with new filters and complete the change. Please advise. Thx

@"LMSC"#p11652 after the new filters are in, as with any filter change, the system should be flushed around 5 or 10 litres

pandabear I always ask @DavecUK about TDS levels. I have to admit I have never descaled. If you mean my machine, then the point of RO to me, is to prevent the need. I did not know you could/should descale your OSmio! I am in a relatively soft water area.
