Review on 🧪 Supco D111 Copper Drier: Reliable Moisture Removal Solution in Compact Dimensions by David Perry

This filter drier was supplied without rubber caps on the ends. There is no indication that the dehumidifier is already contaminated with moisture. My logical conclusion (since there were no caps) is that it is contaminated with moisture and unusable. When the dryer is exposed to the atmosphere, it absorbs moisture and can no longer do its job. I ordered this because it has a Schrader valve, but it's useless if it doesn't come vacuum sealed. . I would have been better off ordering a set of 5 (no valve) for $15 rather than this $20 set. At least then there is a chance that one of the 5 would have been sealed. I will have to return it.
