Hard to get these filters to last 30 - 60 days with constant use. Even flipping filter daily with 12-16 hrs of use can barely get 30 days before filter is hard and crusty.

The filters arrived on time, and the new blue wrapping on them seems to keep them cleaner and in better condition that the older pure white ones. The price is a tad high, but if these last even twice as long as the older ones I had, they'll be worth the cost in the end.

These filters are far more better than the one that came with the humidifier. They last longer and work better.

I am very happy with the new replacement filters which include a blue pre-filter layer. While the older filters seemed to lose their shape quickly, the outer layer on this filter helps it to maintain its shape. I hav only been using it a couple of weeks so I'm anxious to see exactly how long it holds up.

I buy your product and yours alone. There are plenty of after market filters that I could have purchased. Since it's for Mom's humidifier it has to be the best. Mom is good and I have peace of mind.

These filters are a longer-lasting upgrade to models I purchased last year, and a must-have for anyone susceptible to colder temperatures/related aliments in the winter months.
