Product review (5 stars): Works great, good price.
I have three Honeywell humidifiers in my house (one for each bedroom). So I buy these filters fairly often. A quick comment about the type of humidifier that uses filters like this one--- they work 100x better than the ones that blow a mist. With a new filter and the humidifier on high, in the middle of Arizona summer I can turn any room into a sticky swamp (I don't do that though). The only drawback is having to buy new filters every 3 months.

To be clear, this product is called a "filter" but its primary function is to hold water to be evaporated as the fan sucks air through it, similar to an evaporative cooler pad. I think a better name would be "water/air membrane" or something.

There are basically two kinds of filters for these humidifiers. This one, which is the most common, and one with a blue cloth surrounding the mesh part. The blue cloth is for catching dust and providing an extra "air filtration system" for your room. I think that these filters do just fine without the blue cloth.

You can get more life out of a filter if you turn it over once a week or so. Over their lifespan, they'll provide less and less humidity until having the fan on high doesn't cut it, and then you buy a new filter.

As I said, I buy a lot of these filters, and this one is exactly like all the other 3rd party makers, and the OEM filters... they all work well. I guess it's hard to screw up producing these.

I bought this filter at a discount in return for an honest review.
