What does your site stop buying?

Enter what you use today. The calculator returns the bottles a point-of-use system takes out of circulation, with the assumption shown.

Assumptions: 2 litres per person per day, the figure used throughout this site. 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.

219,000bottles or gallons taken out of circulation over the period
36,500litres produced on site each year
1,92119-litre gallons this replaces each year
48 m³of water a year no longer pumped from wells, aquifers or the mains with the Air range, which makes water from the air. About 145 m³ over the period.
฿949,000your bottled water budget each year at the price entered. About ฿2,847,000 over the period.

Thai islands such as Koh Samui live on limited reservoirs and groundwater. In the dry seasons of 2023 and 2024 the island rationed its tap water and many residents bought water by the truckload.
