Made for Boats, RVs, Closets and Basements
Fresh air, no added fragrance
Activated charcoal absorbs odors instead of covering them up. The formula is unscented, so the space smells like nothing rather than like perfume.
13 oz, larger than standard moisture buckets
More absorbing material in every container, and each one covers up to 250 sq ft of enclosed space.
Built for a boat, used everywhere
It was made for cabins that sit under a cover in salt air for months. That is why it holds up without any fuss in a closet, a basement or the back of a car.
How it works
1
Peel and place
Take the lid off, peel the foil, leave the white mesh, snap the lid back on. Set it down and walk away.
2
The pellets pull the damp out
Spherical calcium chloride draws moisture straight out of the air. The pellets bind together and dissolve as they work.
3
You watch it fill
The collected water gathers in the base. The container is semi-transparent, so you can see it and swap it when it is full.
Why people buy several at once
These work by being spread out. One container per enclosed space, because the air in each one is sealed off from the rest.
How fast each one fills depends on the space. A covered boat in humid air fills faster than a dry closet, which is why the container is semi-transparent.
Real customers, on and off the water.
What customers say
I live in a Florida condo, so cross ventilation is hard to come by. Refreshes my closets wonderfully.
I keep one in my old (1999) Ford ranger pickup truck that is damp inside. I can't believe the difference. Works as stated.
Small but mighty!!! I use this in my car as I have a leak (unknown location) when we have heavy downpours. My car dries quickly and the damp smell is completely gone. Love this product!
I use these in my house. This summer has been hot and muggy. Great product! Easy to use and not just for your outdoor big guy toys. Perfect for any room you have a ton of humidity!

Questions
It went hard as a rock. Is it broken?
No, that is it working. The white pellets bind together and set into what feels like a solid block. That block IS the absorbed moisture being held. As it keeps pulling moisture in, the block gradually dissolves and water collects in the base of the container. Hardening first, then dissolving, then water in the bottom, is the normal sequence. Replace it once the pellets are gone and the base is full.
How long does one last?
It depends entirely on the space. A covered boat in humid air fills a container far faster than a dry closet with the air conditioning running. That is why the container is semi-transparent. You can see the collected water and swap it when it is full.
How do I start it?
Remove the lid, peel off the foil cover and leave the white mesh intact, then replace the black lid and set it on a flat surface.
Where should I put them?
Wherever the air sits still. Closed lockers, cabins, closets, bathrooms, basements, RVs and cars. Spread them out rather than grouping them in one spot.
Does it have a scent?
No. The formula is unscented and the activated charcoal absorbs odors rather than covering them with fragrance.
What is inside it?
Spherical calcium chloride pellets that draw excess moisture from the air, plus activated charcoal. Net weight 13.2 oz. It is an eye irritant and harmful if swallowed, so keep it away from children and read the cautions on the label.
What comes in each bundle?
The 10 bucket bundle is one 6 pack and one 4 pack. The 18 is three 6 packs. The 24 is four 6 packs. It all ships together in one shipment.
What if they are not right for me?
Contact support and we will refund you, no questions asked.
