After considering the wide range of distillers they have, I contacted and sought guidance on the best model for use with a CPAP machine humidifier. The girl I spoke with did not suggest the most expensive, just the most practical. This order arrived quite quickly to my Melbourne address. It is somewhat larger than I expected, but well packed and seems quite robust. Reading the other comments, it is not too noisy and the water and timer levels are set so that it doesn't run dry. I've only used this once, to ensure everything was in order, but am very pleased with how it performed. The 12 month warranty should mean that it pays for itself while still under warranty. Would recommend this with confidence.
