Has anyone purchased and used any of those?

Or at least has a relevant info on the subject?

Below are links to 3 different Philips systems.

There's a significant price difference between the first one and the rest:

The AUT3234 is not RO.

 

The AUT2015 is RO, not sure from the data if it has a built in tank or what.

 

The AUT7000 is RO, it has a built in 8L tank with UV.

 

I would look very carefully at the cost of the replacement filters, they are non-standard so you are at the mercy of Philips to keep making and supplying them.

You're right, I've missed that. Thanks for pointing it out on the AUT3234 not being RO.

The RO filters claimed to have a very long service life - 3 years.

The RO membranes do have a long life, it's the particulate / carbon / resin combined filter that needs regular replacement, and of course you can't just replace one element if, say, the particulate filter gets clogged.

 

It's all in a nice compact box if that's what you like, but it doesn't seem to do anything that a 4000 Baht Mazuma or whatever does.

Yeah, that's precisely my dilemma.

How good those 4000-5000 Baht systems are (and the replacement filters).

I have never owned a RO system before.

The compact high-tech systems are very expensive and very proprietary which guarantees their authenticity.

As compared to the traditional systems.

There is a million of them on the market, all coming from unknown sources with unknown quality of bundled filters.

The same applies to the replacement filters.

We have a mid-price Mazuma (a known brand), 3 stages (particulate, carbon, resin) + RO + finishing carbon (no UV). I think the latest version is about 8k Baht.

 

Never replaced the RO membrane, been going 10 years.

 

A full set of genuine Mazuma filters (not including the RO membrane) is about 1,500 Baht, off brand ones can be much cheaper.

 

I change the filters when Madam says the water tastes "bad" (I can't tell any difference), I just replace the carbon and particulate, our water isn't "hard" so I don't bother with the resin unless it's on offer with the others. In reality the filters get swapped out once a year or so.

 

We have a whole-house crunchy-bits filter which catches the big particles before the water enters our storage tank, I change that when the tank becomes slow to fill, it's usually the colour of very stewed tea by then.

 

The cheapest RO I've found is from Close (never heard of the brand) and it includes UV for around 3,500 Baht.

Not sure if I would buy down at that price point but it takes standard cartridges.
