Product review (4 stars): It does the job
If you have the appropriate Honeywell vaporizer, this will fit. Makes sure the model is correct.

It keeps the water cleaner for vaporizing, and is thick enough to wick enough water to provide a good mist amount.

It dries over about 12 hours, so be sure to take apart the vaporizer in the morning to prevent it from growing mold, etc.

I love my vaporizer, and this replacement filter is exactly like the original. It's a good filter to be sure.
