### ⭐⭐⭐⭐ 







  
  
    Problem fixed
  

*by J***N on Reviewed in the United States on 7 February 2022*

I am updating my review. The seller recently sent me a new filter that had addressed the issues mentioned in my first review. I can report that the filter no longer leaks the tiny filter beads. When dry, the filter still appears to be 1/3 full, however, the beads absorb a good amount of water and once thoroughly soaked expand to fill the majority of the filter housing. Nice job and thank you for addressing the issue.

### ⭐ 







  
  
    Do NOT buy this filter
  

*by J***N on Reviewed in the United States on 24 January 2024*

As others have noted, it leaked beads (even after soaking for twenty-four hours in the sink, where the filter also leaked beads) into my humidifier. Just a mess and not sure if damage has been done to my humidifier, or if these beads are toxic. Total waste of money and time.

### ⭐⭐⭐⭐⭐

Nice cartridges for my dehumidifier. Works very well.
