About the PureAir20
The PureAir20 is an atmospheric water generator: a machine that extracts moisture from the air itself and purifies it into high-quality drinking water. Thailand's naturally high humidity makes it an ideal environment for the technology — the more humid the air, the more water the unit produces, often exceeding its rated output in coastal and tropical areas such as Koh Samui.
How it works, in four steps:
- Air In: Ambient humidity is drawn through a medical-grade HEPA filter, with no reliance on pipes or existing water infrastructure.
- Condense: The air is cooled to its optimal dew point, condensing pure water vapour directly from the atmosphere.
- Purify: The water passes through multiple filtration stages, including sediment filtration, activated carbon, reverse osmosis, and UV-C sterilization.
- Mineralize: Essential minerals are reintroduced and balanced to an alkaline pH, producing water that's ready to drink immediately — hot or cold.
9-Stage Filtration
Every litre passes through nine independent purification stages before it reaches the tap:
- HEPA air filter
- Condensation
- Tank UV-C
- Sediment filter (PPF)
- Pre-carbon filter (GAC)
- Reverse osmosis
- Post-carbon filter (T33)
- Softening (SFT)
- UV treatment and remineralization
The result is water that meets NSF/ANSI 42 and 58 standards, WHO drinking water guidelines, and Thailand's own TIS 257 water standard — with a balanced, alkaline pH of roughly 7.4–8.2.
Key Features
- 20 litres per day of pure, mineralized water (rated at 30°C / 80% RH — easily achievable in most of Thailand)
- Hot and cold dispensing on demand, from roughly 5°C to 95°C, with a child-safety lock on the hot tap
- Whisper-quiet operation at just 45 dB
- No plumbing required: simply plug in and start producing water
- Compact footprint, designed to fit against any wall at home or in the office
- Zero plastic waste: each unit eliminates thousands of single-use bottles per year
