Great Humidifier
The humidifier was shipped in the box it would have been sitting on the shelf and was not put in a shipping box. When it arrived the box was destroyed and taped everywhere. I was surprised to find everything was intact inside. This is my second Puregardian humidifier. Last one purchased 6 years ago and still works great. I now have one for for each level. The new unit puts out great mist like the original, very quiet, works just as it should. I would purchase again. I dump excess water after each night and let everything dry out, so as to mitigate mold. Great for using through the evening and night. I also use the ceramic insert from pureguardian.

It feels different and it
It feels different and it appears that I'm sleeping better. I love how quiet the unit is. Perhaps reverse the panel on top to bottom and have the water source on top.

Very impressive and QUIET
We bought this to replace an old Homedics after doing some initial research. I was a bit hesitant after a positive experience with my last product, but ultimately took the leap and am thrilled with my purchase. It's so incredibly quiet - my husband is amazed! The simple, empty indicator light is easy to spot as well. We're very happy and purchased two other models for the house. Will definitely recommend!
