40 Pieces Humidifier Filter Cotton Refill Travel Mini Humidifier Filters Sticks Car Humidifier Replacement Parts for Portable Personal USB Powered Smart Humidifiers in Office Bedroom (5.9 Inch)

This item (5.9 inch filter) fits perfectly in the Treva portable humidifier (model AEHB002).I soaked the filter in cold water for 5 minutes, before installing. It's working fine, without any issues.

Works great! Good product.

They are 4 in. long as described.Unfortunately, the unit I ordered needed a longer ones (4.25 inches). The humidifier seller did not specify the length in its description, so now I have slightly shorter ones, which work OK if I keep filling the unit.

I needed additional cotton humidifier sticks for my new desktop humidifier and these fit and work well. In the attached photo are my humidifier device and these replacement sticks on the left with the OEM stick on the right. These are slightly longer, but they fit. I will trim them a bit so the fit is not too tight and the holder does not come out.

Needed replacement filters for my Hewy Dewy and these worked.

Good

Not cotton as it was advertised. Received them and they're foam in the middle. Will be returning.

Size is perfect; such as description.

Exactly what I was looking for, for a low price point. Overall satisfied
