CHILLWELL AC FILTER only the filter, use for backup, freeze for beat cooling

For sale is one filter for Chillwell AC portable unit- filter only. Great if you need a replacement or would like a backup- they work really well when you wet them and place in freezer, so this could be the secondary one you freeze when you are using the current one and then you’ll always have a cold one. LOVED my unit, but bought 2nd hand and the electronics are not functioning correctly and this filter will not fit the brand I tried next. NOT for Chillwell 2.0 I don’t believe.
