No internal reservoirs, no change of flooding


No chance of flooding due to its operation without internal reservoirs. Micro-pumps control the water injection and ejection. In the third stage, the wick takes out excess water vapor before it even reaches the optics.

New wick design, more time for research


We have eliminated the frequency of exchanging contaminated wicks with our new wick design. With this new design, operation time is six months and longer with the same wick.


The new design can even stand up to tap water however we still recommend to use distilled water to reach and exceed the lifetime.
