Order 2 at the same time, one became clogged almost immediately.
Have used these for years, familiar with the product.  Recently ordered 2 so I could alternate their use to let moisture evaporate.<br /><br />The first one I used became clogged within about two days.  The second one is working as expected though.  Having weighed both of them, the clogged one is about 4 grams heavier than the one that works correctly.<br /><br />Did I get a previously used product or was it just defective?  Either way I wasted $15 and I'm kinda tired of buying this plastic junk all the time.  Will be looking to make my own using store bought air fliters with a metal or ceramic casing.
