Drinking water and CO2 refills in Koh Phangan.
Minairal has a point in Thong Sala, inside DELITALY, where you can swap a CO2 cylinder on the spot and get help with your system. Installation and maintenance come from our head office in Bo Phut, Koh Samui, a short ferry ride away.

What Minairal does in Koh Phangan.
Mineral drinking water made where it is drunk, from the humidity in the air or from the existing water line, for homes, villas and businesses on the island. One team looks after it from the first visit onwards.
Site assessment
The Koh Samui team crosses to your site, counts the users and the points of use, and checks the water connection. You receive a configuration, a capacity and a maintenance plan.
Installation
Machines are checked and configured before they leave Bo Phut, then placed, connected and tested on site. Every installation ends with a report signed by both parties.
Maintenance
Preventive checks, filter replacement and cleaning on schedule, by Minairal technicians. The pre-filter is replaced every four to six months depending on the system, the other cartridges every twelve months.
CO2 exchange
For soda makers, bring an empty CO2 cylinder to our point in Thong Sala, inside DELITALY, and leave with a full one straight away.
Water on the island.
As elsewhere in Thailand, mains water on Koh Phangan is not intended to be drunk at the tap. Depending on the season it can carry chlorine and its by-products, sediment and heavy metals, with a bacteriological risk wherever the network is old or intermittent.
Bottled water is the usual answer, and on an island it travels furthest. Every litre crosses by boat, continues by road and leaves again as waste. At two litres a day in half-litre bottles, one person accounts for 1,460 bottles a year.
A system that makes water on site breaks that chain. Water from the air needs only a power socket, and water from the line is filtered where it is poured. Either way, nothing is shipped in and nothing is thrown away.
Air or Pure on Koh Phangan.
The technology is decided at the site assessment. On the island, the first question is how far the water connection can be trusted.

Air
An Air system condenses humidity from the air and treats it on site. It needs a power socket and no plumbing, so it suits villas, bungalows and points of use far from any pipe, and it keeps producing when the network does not.

Pure
A Pure system connects to the existing water line: five-stage reverse osmosis at 0.0001 micron, remineralisation, hot 90°C and cold 4°C. Installation takes under an hour. It suits kitchens, cafés and any point of use with a dependable supply.

The configuration changes with the site. The water and the service do not.

Is tap water on Koh Phangan safe to drink?
Mains water is not intended to be drunk at the tap. Depending on the season it can carry chlorine and its by-products, sediment, heavy metals and bacteriological risk where the network is old or intermittent. Our guide to tap water in Thailand covers the options.
Which works better on the island, Air or Pure?
It depends on the site. Air needs no water connection and keeps producing when the network does not. Pure filters the existing line and gives a stable output.
The choice is made at the site assessment, on four questions: the water connection, the daily volume, the space and the need for continuity.
Elsewhere in the network.
Three service centres with parts held in each, and coverage across four provinces.
