In general I do trust the LifeLabs brand.  I do like this product as it purifies the air in my home quite well.  I like that the product has several fan speeds, provides alerts for maintenance and is easy to use.  I would say that the color is a navy blue though and not grey.  I like the structural design but wish the whole product didn't look so mechanical.  Perhaps all one color and not a see through container.  Recommend.
