My firm purchased a couple of the Honeywell Humidifiers for the dry winter air in our office. The product works wonders and replacing the filter is very easy. The price is the best straight from Honeywell, so why buy it from a third party? We will be purchasing replacement filters again in the future. Thank you for a great product!

So far, so good! I like that these filters aren't as bulky as the old ones. I live in an urban area, so I like that this blue pre-filter is there to ensure even better air quality.

Reviewed: 12/10/2019 by Christine Norquest

I ordered this to replace my last replacement filter, which was also Honeywell, but ordered from a different website. The first replacement didn't last long - smelled horribly right away, despite following care instructions and didn't fit properly it was big. This new one arrived quickly, and feels like its well made. It fits properly and has the additional antimicrobial lining, which seems like a plus. I am happy with it so far. I knocked a star off because when the system runs out of water for just a few hours, maybe while Im at work, the filter takes on a musty smell. Its not as bad as the first replacement filter, and it goes away as soon as I refill the water tank and turn it back on. Will order this filter again from Honeywell directly when I need to replace it because Im happy over all.
