Dri-Z Air Refill Crystals - 13 Oz.

This product is great if you need a 3% to 6% humidity drop if did not drop my humidity level any more than that bug it's easy to use it's small so it fits in a corner of a grow tent or room and requires very little attention.

This is the 2nd year using this item in my RV and it work’s absorbs all the humidity. I recommend it.

Hello,These "crystals" work great at keeping the humidity down on my houseboat. I live on the coast in Washington State and the humidity is high in the winter. I use these crystals to keep the humidity down. One refill pack fills a container and you get about three cups of water out of one refill. The crystals are depleted depending on how humid the environment is. In my case it takes about three weeks to deplete the crystals then I need to refill.Take care,Bill

they do a good job taking moisture out

This product works exactly as it was supposed to. loves it

First time using this and couldn’t believe how much water it pulled from the air. Great for storage

I use these in my RV to keep moisture down. I live in FL and only use my RV once every few months. Since I used these for 6 months now I never have any of the usual areas getting mildewed anymore. I had to dump and refile once a month. Very satisfied.

Works great - or else we have no humidity in NE Oregon this winter. Used in three Dri-Z-Air pots in 18' camper stored outdoors for past 3+ weeks with windows cracked in weather with snow and rain - just a few drops of water in each pot after three weeks.
