Product review (1 stars): Caution- better purchase the True Air filter instead
I purchased this Graco filter for my True Air humidifier because the Graco humidifier is identical to my True Air (with the obvious Graco label slapped on instead).  As another reviewer already indicated, this filter is horrible and does not perfom like the True Air filters.  I purchased this filter at BRU because that is where I got the humidifier and I cannot find the filters at any other brick and mortar store.  First, the filter is entirely white, lacking the silver lining on the outside like the box picture clearly shows.  The True Air filters always had a blue lining on the outside of the mainly white filter.  Second, after ONE nightly use it was already brown in spots.  I can use my filter for several weeks, by following the manufacturer's instructions to run the humidifier after the water container is empty, to dry out the filter before storage.  Finally, the filter did not get wet as the True Air filter did.  Only the bottom got wet.  Even when I pushed it into the water receptacle more firmly, the filter still became wet on just the bottom, rendering this filter completely useless in my opinion.

Don't waste your money on this brand.
