Excellent product and service.

We have been using the filters and Protec cleaning cartridges for several years and have always been very pleased. Service is also excellent and the Honeywell name is as good as always.

Great Filter

This filter does a much better job of wicking water for humidification and holds up much longer than other generic filters. I will only buy this filter for my humidifier.

Filter

These filters were backordered, and I was afraid they would be indefinitely unavailable, but I went ahead and made an order anyway. I was pleasantly surprised when they were shipped a month or so later. They are high quality filters- would definitely recommend.
