Whilst better than the basic humidifier filter, I still get a lot of congestion and sneezing with this. Hopefully better in summer
I fitted this to see if I needed more humidity that the HumidX. In Melbourne it was a little too much (felt wet) but during an air flight and in Europe, it seems to be about right. I definitely provides greater humidification that the HumidX but you need to test whether you need the higher level.
