Olivia W. ★★★★★ Oct 19, 2026

The mineral release is noticeably lower since I installed this cartridge, and my air actually feels cleaner. It was a simple swap that took less than a minute, and the difference in our bedroom humidity is real.

James ★★★★★ Oct 18, 2026

Finally got around to swapping the old cartridge and noticed the mist feels crisper without that chalky smell. It slides right in and the replacement interval seems spot-on based on my water usage.

Installed this in my DREO 774S and the mineral buildup on my furniture has noticeably decreased after just a few days. It was simple to swap in and fits perfectly.
