1. AirJoule

• Founding Year: 2024
• Location: Newark, Delaware, US
• Use For: Water Security and Decarbonisation

AirJoule develops an atmospheric water harvesting system, AirJoule. It utilizes sorbents and proprietary metal-organic frameworks (MOF) technology to extract per- and poly-fluoroalkyl substances (PFAS)-free, distilled water from the air. The MOF-coated contactors draw air and capture water vapor. Once the MOF is saturated, a vacuum triggers the desorption of the vapor.

A vacuum swing compressor (VSC) condenses water vapor into liquid water. This process takes place in a dual-chamber system where water vapor capture and release cycles occur simultaneously, enabling continuous operation and efficient heat recovery.

Moreover, AirJoule operates without harmful refrigerants and provides a sustainable alternative. Working in both humid and arid environments, it addresses water scarcity in industrial and commercial settings.

2. Aqua Ubique

• Founding Year: 2023
• Location: Birtinya, Australia
• Use For: Atmospheric Water Generation

Aqua Ubique develops atmospheric water generators to address water insecurity. Its generators draw in air, cool it till water condenses, filter, and remineralize the water.

The solution gives access to safe drinking water as compared to tap water, which may contain arsenic, uranium, or harmful microbes. It also diminishes single-use plastic bottles and water deliveries. Consequently, it eliminates the associated carbon emissions and pollution.

3. Untap!

• Founding Year: 2024
• Location: Sollentuna, Sweden
• Use For: Off-grid Water Production

Untap! provides off-grid industry-grade water via its AWG. Its AWG uses atmospheric water condensation that absorbs the humidity in the air and transforms it into drinking water. It incorporates multistage filtration and ultraviolet (UV) light treatment to ensure water quality.

Moreover, the startup deploys sustainable power sources for its AWG, such as solar, wind, biofuel, or grid supply. This minimizes carbon emissions in the water generation process. The AWG is off-grid and also operates in rural areas with limited infrastructure.

4. ATMOS

• Founding Year: 2023
• Location: Hyderabad, India
• Use For: Residential, Commercial, and Industrial AWGs

ATMOS manufactures AWGs for residential, commercial, and industrial applications. Its air-to-water technology extracts moisture from the air using biologically inspired surfaces, filters it, and transforms it into drinking water. The AWG filters incoming air to remove airborne contaminants and ensures only clean air enters it.

Further, the startup applies multistage purification of water, such as UV treatment, ozonation, carbon filtration, reverse osmosis, granular activated carbon (GAC), and more. This facilitates the removal of microbial contamination, odors, organic compounds, dissolved solids, and particulate matter.

The startup’s AWG also adjusts the potential of hydrogen (pH) and mineralizes the produced water to add nutrients like calcium and magnesium for improving water quality.

5. AERstream

• Founding Year: 2024
• Location: Miami, Florida, US
• Use For: Countertop Water Purification

AERstream makes countertop water from air machines. Its patented air and water filtration system removes bacteria, allergens, and toxins to ensure safe drinking water. The AWG incorporates replaceable filter cartridges, which allow easy maintenance for users.

Moreover, its compact and portable design enhances convenience for residential users, businesses, and remote areas.

6. Hydrexa

• Founding Year: 2023
• Location: Dubai, UAE
• Use For: Atmospheric Water-based Air Conditioning

Hydrexa’s technology harvests water vapor to produce drinking water, regulate humidity, and deliver energy-efficient air conditioning. It integrates technologies like AI and the internet of things (IoT) for water quality monitoring and remote management.

The startup’s solutions extract water directly from the air and reduce dependence on depleted water sources for regions facing water scarcity and high cooling demands.

7. ExaWater

• Founding Year: 2024
• Location: Seattle, Washington, US

Aeraqua Solutions designs AERAQUA-10, an AWG for homes, offices, and areas with a lack of access to clean water. The AWG incorporates filtration technologies like poly aluminum chloride (PAC) composite, activated carbon, and UV treatment to remove contaminants, odors, chemicals, and microorganisms.

This ensures water quality is safe for drinking. It also automatically circulates the produced water through disinfection modules, keeping the water clean.

Further, the startup’s Aeraqua Simulator platform uses real-time location-based weather data to forecast the water yield in a given period, allowing users to plan and manage resources. Another cloud-based platform, Aeraqua Terminal, facilitates remote monitoring and control of AWGs. This allows users to track water quality and system health for smooth functioning.
