Review on Enhanced H75-C Expanded Wick Filter for Optimal RPS Performance by Donald Cummings

Based on some of the other reviews here I suspect that not all filters sold by this company are exactly the same. The ones I have are without a doubt the best I've ever had for my moisturizer. The humidifier is about 6 years old and believe me I've tried them all. Most other brands were very soft after cleaning. In fact, something fell apart. If I tried to descale the filters with a vinegar bath, they worked well for a short time, but were unusable after 24 hours (according to the sensor on the humidifier). They were very different; I have very hard water and after a few weeks the filter was mostly clogged. I took a vinegar bath and rinsed it out and let it sit for a couple of hours. This would kill other filters. After a good flush, the filter still had some "body" and ran like new. That was about 3 weeks ago; maybe it's time for another cleaning, but I can say that these are the most durable filters I've found; They also stand up to cleaning. I just hope that if I have to order more, I can get the exact same material.
