waters

Hi All, we've lived in a condo in central Bangkok for several years now. We've relied almost exclusively on bottled Aura Mineral Water for our drinking water but would now like to switch to a water filter system (to reduce plastic bottle waste, and maybe overall costs). I've seen systems from Stiebel Eltron, and Mazuma in the forums, as well as this post from 2016 - https://aseannow.com/topic/940312-what-drinking-water-filter-do-you-recommend/ I understand the basic difference between RO and non-RO systems, and am not particularly worried about mineral content as we're likely to get enough of the important minerals from other sources. Taste might be a factor. These two systems from Stiebel Eltron look pretty good - Stream 5S https://www.stiebel-eltron.co.th/en/home/products-solutions/water-filter/drinking-water-filter/domestic-use/stream-5s/stream-5s--ste-.html Glacier (STE) - RO - although not shown in the pictures here, pretty sure it requires a tank. https://www.stiebel-eltron.co.th/en/home/products-solutions/water-filter/drinking-water-filter/domestic-use/glacier/glacier--ste-.html There are other more modern 'tankless' RO systems - although they might have to be imported, like.. SimPure T1-400 https://www.amazon.com/SimPure-T1-400-UV-Tankless-Filtration/dp/B0B14TM99T The big issue with a system like this I think would be getting replacement filters. I don't think we have space for a tank - although we own our unit, and so could install a 5 stage system on the other side of the wall from our kitchen sink (in our bathroom, on a wall that has water, drain, and power) and route the tap through the wall to appear just above the sink next to the normal tap. Our main concern is general drinking water safety - especially as we have a 6 year-old. Anyway - was wondering if there were any 'Bangkok water gurus' in the forum would might be able to share some advice?
