How HyperVent Prevents Marine Condensation

HyperVent is a spun polymer bonded to a breathable fabric.
The ¾ inch polymer loops will not compress, allowing plenty of dry air to circulate wherever it's placed.

What Hypervent Customers Are Saying


I installed the HyperVent material under the foam mattress on my 33' power boat to control condensation. The HyperVent did the trick.

Paul Flynn

We used HyperVent this year under the V berth on our 28' lobster cruising boat with great success. It allowed air to circulate under the cushions eliminating any moisture that might have been looking for a home.

Bob McBride

Two layers in the bottom of the refrigerator keeps foods and beverages above any water accumulation. Lining settee storage lockers solved a mold growth problem by eliminating condensation on the hull.

Jim Ripple

My experience with this system is so much better than with other products I've tried. I can enthusiastically recommend HyperVent.
