Summary: Still wondering if it makes sense
Comment: The humidifier itself is the best we have so far, quiet and reliable. We purchased it more than 4 years ago. My question is whether or not the filters make sense. I mean, you can buy for less than $30 a humidifier that runs without any filter at all, there are many brands available. While this one will eat up 1 filter every month or less depending on the type (and quality) of water you get at home. We use it only at night, every night, during winter season or as long as the heating is on. I empty the tank every morning and I clean it either with Clorox or diluted vinegar once a week. Still, by the beginning of the third week or sooner, you see the black spots (fungi) in the filter. By the end of the same week it smells. For some reason I prefer this filter over the one we use in another humidifier we have (katz). Although the life spam of both is very similar.
I want to believe the $7+ I am spending on every filter give us a cleaner humidity than the humidifier that runs without filter. Although so far nobody was able to confirm this to me.

Comment: I ordered these filters for my humidifier. They fit & worked just as the filters did that came with my humidifier. Nothing special to report on these filtes.

Summary: substituted an inferior model filter
Comment: I ordered the Honeywell HAC504. Allergy Be Gone sent the HAC504AW. This is an inferior filter and does not last near as long as the HAC504. Now I see they will not refund the shipping charge and there is also a 10% restocking fee. I won't submit an order to Amazon for a long time.

Summary: Humidifier Filters!
Comment: The BEST filters I ever used. I am breathing better and I can walk further than ever before! Thank you.

Summary: never again
Comment: Is there anywhere to buy the old filters without the blue wrapping.
I have used Honeywell Humidifiers for many years and never had the smell / mold problem you do with these filters, they are downright unhealthy.
I tried to rate these zero stars they are that bad but the system would not let me.
Please go back to the old filters
