Product received in good order just as expected. But shipment was originally scheduled for 3 business days only to take 5 days to arrive. Attempts to check on the shipment were greeted with responses from the carriers that they had no record of the shipment.

Good product. The innovative Honeywell design does prevent limescale from building up in the humidifier, unlike much more expensive humidifiers I've used. Make sure to follow the instruction to flip the filter in between water changes. In my experience they need to be changed after a month of regular operation to avoid bad smells.

Reviewed: 02/13/2020 by Laura Michaels

So impressed with the performance and longevity of this new filter design! Using this new replacement filter, which now has a blue outer-shell, in combination with the Protec antimicrobial cleaning cartridge, saves me money and saves resources. This filter style seems to last 4x as long as the prior filter, which did not have the blue outer-shell. It is a relief not to have to replace the filters as frequently.

Rating: 4/5Rating: 4/5Rating: 4/5Rating: 4/5Rating: 4/5Overall good product, just a little pricey

Reviewed: 02/13/2020 by Michael Stone

I appreciate the newer filter design which has the blue casing. In addition to being a pre-filter, it does make handling a wet filter much easier, which is somewhat important when you're flipping it everyday. Running my humidifier daily has become a pricey habit, as these filters end up getting changed every 3 weeks. I do use a water treatment additive but mildew inevitably still shows up in the filter after a couple weeks. Overall, a good product and have not received any defective ones so far.
