After over 30 years in the offshore oil & gas industry, I have been on many different types of platforms and rigs. Typically, we have a high percentage of personnel that suffer from various sinus issues in our offshore living quarters. In the winter months, it is usually much worse.
We utilize the Synexis Biodefense System on all our facilities. I have noticed that, summer or winter, we have very little complaints from anyone of congestion or the normal spread of colds or viruses. The (units) are very easy to service by onboard personnel with minimal training. The folks at Olivier Biodefense are always very helpful, and they are very quick to respond to questions or comments you may have.
I highly recommend these units.
