elasto is now the only company in the promotional products industry to offer the innovative air up® bottle engraved with a capacity of 480ml.

How air up® works.

air up® is the world's first refillable drinking system that gives water flavour through scent alone.
In contrast to infused water, for example, with air up the taste is separated from the water. The basis for this is the physiological phenomenon of retronasal smelling.

And this is how it works:

A pod filled with natural flavours (e.g. cherry or apple) is placed on the mouthpiece and as soon as you drink from the straw, you also draw flavoured air into the throat along with the water. The aroma molecules are then perceived as a taste when you exhale.
