How many plastic bottles will you stop buying?

Three quick answers. The result is for your site, at two litres per person per day.

Step 1 of 3

Type of place

The same water, made on site: filtered and remineralised with calcium, magnesium, potassium and sodium, served hot or cold.

Assumptions: 2 litres per person per day, the figure used throughout this site. Plastic per container, conservative industry averages: 10 g for a 0.5 L PET bottle, 28 g for a 1.5 L PET bottle, 15 g per 19 L refill (a reusable jug of about 750 g, counted over 50 refills). Water used to produce bottled water: 1.32 litres per litre sold, the litre in the bottle included (IBWA, Antea Group study, 2015); the Air range draws nothing from wells, aquifers or the mains, the Pure range filters your existing supply. Bottled water budget: defaults are averages of public online prices for natural mineral water at Thai retailers (Tops, 7-Eleven, Lotus's, Makro) in October 2026, ฿13 per 0.5 L bottle and ฿23 per 1.5 L bottle; ฿20 per 19 L refill is a typical island refill price. All three are editable; Minairal prices are not included.

Two ways to produce it on site.

Both end the same way: filtered water, remineralised with calcium, magnesium, potassium and sodium, at an alkaline pH. What separates them is where the water starts.

Air

An atmospheric water generator turns the humidity around you into fresh drinking water, with nothing to ship and nothing to throw away. The unit condenses humidity from the air and treats it on site. No inlet, no connection to the network, so the supply exists whether the mains does or not. For larger daily volumes, the Air Stand Pro produces 22 litres a day on average, and up to 30 litres.

bottles a year, for one person.

At two litres a day from half-litre bottles. Multiply by the people on your site and the years the system runs. The saving is not only plastic: it is bottling, the boat and truck freight to an island, refrigeration on the way, and disposal afterwards.
