Carbon dioxide filters, air purifiers, and DAC equipment

In the past, it has not been possible to remove carbon dioxide from indoor air, the only way to control the carbon dioxide level has been to increase ventilation. UniqFresh air purifiers are also able to remove too high concentrations of carbon dioxide, which means that the cleaned indoor air is even better than the replacement air taken from the outside. With the Uniqfresh air purifier, indoor air quality improves easily and quickly.

Fuel cell

The fuel cell produces electricity from the fuel using oxygen in the air as an oxidant. Electricity generates in the cell as a result of oxidation/reduction reactions in the cell. In addition to electricity, heat also generates. When hydrogen is used, water forms as a reaction product, and carbon dioxide also produces in methanol cells.


Hydrocell was founded by Tomi Anttila.
