Product review (1 stars): A mere shell of its former self
I do not often post such negative reviews, but this product changed without notice since I began purchasing this filter.  It is but a mere shell of what it used to be, as they removed the blue outer layer with the finer mesh...likely to be produced 'cheaper'.  Hence, it no longer filters the air as it humidifies.

Since the humidifier is consistently taking in and circulating the air, it is also now spewing whatever is airborne. Though I keep my household clean, looking at my A/C filter and what it traps when I change it each 3 months, one comes to realize that there is quite a bit of 'stuff' stirring about in your home's air.  Hence, this Honeywell filter is not worth buying ...especially when compared with alternative brands that still include a filter and are still compatible with the Honeywell humidifier.

I am going to try the BestAir HW14, as it seems to have decent reviews from those that have used it...
