Your thoughts about the Water Purifiers / Filter Dispensers?
Just to check if anyone is familiar with some tankless models of water filters/purifiers that I have been asked to check out for my family. My parents are looking to get one.
Researching on my own, I recently checked out water filters from RUHENS and also some model I saw online - COSMO Water Dispenser
RUHENS
Has an atas looking showroom at Ubi area, and the salesperson did a thorough demo for us, even highlighting the fact that their water dispenser does not waste an excessive amount of water when it does the on-the-fly filtering (I subsequently found out that purifiers using reverse osmosis filters would require a large amount of water to flush the filtered contaminants out via a water outlet, which their models don't have. I guess they are using standard sediment filters).
The older model they have has some weird requirement for the buyer to get their servicing package (else warranty void, or something), while the newer and slightly more expensive one allows self-servicing like filter changes. However, the newer model also has smaller filters that are, on the whole more expensive over the longer term to maintain.
COSMO
Apparently, the guys who brought it in are the same people who brought in the Origin Mattress that looks super popular for some reason. The guy did a quick demo and short explanation, and it sounded like something comparable to what Ruhens Newer model can do, though with some added level of control over the temperature. The filter change also self service, not sure if they are using reverse osmosis filters (does not look like it, the fellow also mentioned the machine has no cold water flushing/drainage), need to get the filters from them.
Thing is the showroom looks a bit like a shady operation to me, showcasing their mattress, electronic door lock, and water filter dispenser items all in the same room, with a valiant effort at keep safe distancing for people. Their main product seems to be their mattress, so I am not very confident that the warranty will be valid throughout the whole period. LOL
Checking online, I also saw Purikool and Sterra Water Purifiers. Has anyone heard of Sterra Water Purifier?
The tankless machine they are selling looks like a practical copy of one of the higher end models Purikool is pushing these days (I think it is OHC-7000D or something like that). Their website looks very new, and whatever posts they have are relatively recent compared to the others on the market. I can't tell if they are legitimately sourcing from the same OEM or this is something shady, so taking the cautious approach here.
If anyone has anymore information on any of these, please do share if you happen to know what it is like to use their water purifier (or a similar purifier from other brands). These purifiers are pretty huge investments, hope to be able to find more information before committing a big ticket item for the family. Huge thanks in advance to anyone who can share more details and their own experience ba.
