Aire-flow™ Moisture Barrier

for Mattresses & Cushions


121 Day Trial Period & Free FedEX Shipping


Size/Shape Can Be Customized Upon Request

Are you looking for a solution to mold, mildew, dampness, or moisture build up under your mattress, bunk pads, or cushions?  


The most practical and affordable solution is the Aire-Flow Moisture Barrier.  Simply place the material underneath your mattress or cushions to minimize moisture buildup.


What's causing this problem in the first place?


Mattresses in Boats, RVs, Trucks, and Aircraft usually rest on plywood or other types of flat hard surfaces.  Most of those surfaces provide minimal air circulation underneath your bed. 


When you're sleeping, your body heat increases the temperature of the mattress.  Some of that heat radiates out of the top and sides of the mattress, but a lot of it radiates out of the bottom.  


If the surface the mattress is lying on is colder than the mattress itself (it usually is), that temperature difference can cause condensation to form.  And if the condensation can't evaporate, it can lead to mold or mildew buildup.  


How does Aire-Flow resolve my issue?


Aire-Flow™ provides unobstructed airflow by elevating the mattress off the sleeping surface...kind of a like a magician's assistant in a Vegas magic show. :-)  


When the mattress is elevated, warm air is able to circulate under the mattress which minimizes conditions necessary for condensation.


If condensation does occur, Aire-Flow™ allows that moisture to evaporate.


What is Aire-Flow?

It's a 3/4" industrial-grade woven polymer material bonded to a breathable fabric.  The material was originally designed for water drainage in parking structures and soccer fields.  



  • Allows for unobstructed airflow under your mattress
  • Light weight material weighing only 4.3 oz per sq yard
  • Easily bends around door ways and tight spaces
  • Maintenance free
  • Unaffected by cold temperatures
  • Very strong but flexible (can support very heavy people)
  • Holds it's shape indefinitely and outlasts your mattress
  • Can't be felt underneath your mattress
  • Easy to clean and dry (soaps, hot water, or steam cleaning is ok)
  • Easy to join multiple pieces together.  Simply apply adhesive or tape to a 3" overhanging flap.
  • Easy to cut with a pair of scissors


Aire-Flow™ is available in widths of 39" and lengths of up to 50 feet.


How do I order?

Choose the number of linear feet you'd like from the drop down menu and click "add to cart".  If you're not sure how much you need, give us a call and we can help!


Custom Sizes & Shapes

Need us to cut it to fit your mattress for you or are you unsure of how much length you need?  Give us a call 888-488-1468


Shipping and handling time

This will ship from our plant in SC.  Allow 2-3 business days before shipping.  In a hurry?  Give a call and we can usually get your order out within 24 hours.


Material will be cut to your desired length, and we'll roll it up and put it in a shipping box.  When it arrives, it looks like rolled up carpet.  


Other applications besides boats and RVs:

  • Aircraft
  • Truck campers
  • Semi trucks
  • motorhomes
  • Travel Trailers or Fifth Wheels
  • Pop-up Campers
  • Sleeper Sofas (can't be folded into couch)
  • Homes or mobile homes
  • Apartments
  • Pet beds
  • Dock lockers, boxes, sail and rope lockers, drawers, ice boxes, refrigerators
  • Cans or metal containers to prevent rust
  • Near bilge pump intakes in order to reduce the possibility of clogging.

Aire-flow moisture barrier........what side goes towards mattress?

BEST ANSWER: Hello Elizabeth,
The "smooth" side of the moisture barrier should be up towards the mattress, while the rough "indoor turf looking" side will be against your base.
Kind Regards!
Can i use as tub mat?
A shopper on Aug 23, 2018
BEST ANSWER: Personally I would not recommend this as a tub mat. It does not seem best suited for direct point pressure, such as for feet. It is also backed by a "fabric-type backing that would likely break down with copious amounts of water.
Would this work to put between a ‘plastic’ dorm mattress and a memory foam mattress topper? If so, would it still work if I put a sheet and mattress pad covering all of the layers together (dorm bed, aire-flow, memory foam)?
Kirsten F on Jun 27, 2018
BEST ANSWER: Hi Kirsten! Moisture tends to build up underneath a foam mattress that is sitting on a platform. It is not recommended to place the Aire-Flow between two mattresses. Please give us a call to discuss further!
How abrasive is the plastic side? We need a moisture fix for our hybrid trailer but worried the plastic side will scratch since our mattress are pulled out to pack up our trailer
Derek on Aug 26, 2018
The rough side of the Moisture Barrier is meant to face down, away from the mattress, while the smooth side is meant to face the mattress. The smooth side of the Aire-Flow should not damage your mattress.
Kind Regards!

Can this be used on adjustable beds?
A shopper on May 7, 2018
BEST ANSWER: It is flexible, so it would bend with any adjustments. One issue that may arise is that it would allow the mattress to slip and slide from its platform.
my mattress is wider than 39 inches. 7 foot long do I need full width?
A shopper on Apr 29, 2018
BEST ANSWER: You would need to place two strips of moisture barrier to cover the full width and length of your mattress. Please feel free to contact us at 888-488-1468 for help with figuring how much you will need for your space.
Can I wrap the liner around the edges of the polymer to cover up the rough edges?
A shopper on Apr 22, 2018
Yes, you can use the MB around the edges, between the mattress and the wall to help avoid condensation there. But I'm not quite sure what you mean by the rough edges? THere is no need to adhere the Moistre Barrier to the bottom of the mattress as there shouldn't be any issues with the mattress sliding on it.
Kind Regards!

I have just purchased a Sleep Number Adjustable Top Imattress, and I'm trying to find some kind of moisture barrier that will keep the interior under the top foam sheet and the air mattresses from molding. I only found out that this was a problem when we took our old Sleep Number mattress apart and found black mold growing all over the top foam pad's back. It was extremely gross and unhealthy.
Apparently Sleep Number knows about this problem, but has never informed any of it's customers. They have been sued several times, I don't know what the outcome was. But I want to make sure this does not happen again, inside the mattress cover of my new Sleep Number Bed. Do yo think that "Air Flow" would work in this situation?
LINDA W on Dec 20, 2017
BEST ANSWER: Hello Linda,
Because "air mattresses" can be susceptible to punctures, we would not recommend using the moisture barrier because it is meant to have the smooth side towards the foam of a mattress. This would leave the stiffer rough side towards the air mattress. We would recommend using a blanket or other absorbent material between the surfaces and to check them once a week for any moisture build up. If moisture is accumulating, you will want to wipe the air mattress surface and replace the absorbent material.
Kind Regards!

What do I need for a queen bed? What would the cost be? What about for a king bed? Cost? Thanks
Sharon E on Dec 6, 2017
For a standard Queen size bed, 60 x 80", you would need 10 feet of the moisture barrier. For a king bed, 76 x 80", you would need 13 feet. The cost of the AireFlow Moisture Barrier is $9.99 per foot. It may be ordered online by the foot and easily cut with scissors. If you would prefer we cut it to size for you, please contact us at 888-488-1468 (There is a cutting fee for this customization.)
Kind Regards!
Hi, I'd like to buy this for three beds in my RV, the site says $9.99 per linear foot and is offering an additional 5% off with a coupon code "extra5" but it also says the sale ends today (December 2, 2017). It is now 8pm PST, I tried to call but am sure you are all closed up for the night. If I call again tomorrow or Monday, whenever you are next open, will you honor that price for me?

What material(s) is this product is made from and are there any flame retardant chemicals or other barriers used for fire safety?
Lynne on Aug 27, 2017
BEST ANSWER: The Aire-Flow Moisture Barrier Mat is a special material that consists of a spun polymer woven into a large open configuration that is bonded to a breathable fabric layer. Because our mattresses are flame retardant, there is no extra fire retardant on the Moisture Barrier.
Bought the site flow barrier. Does the fabric go toward mattress or base?

Will this fold up with a sleeper sofa?
Marla R on Feb 14, 2017
BEST ANSWER: Hello Marla,
The moisture barrier mat is not made to fold easily in to a sofa bed and will most likely not be able to fold with your mattress in to the sofa bed. The mat would need to be stored separately when the sofa bed is not in use.
Kind Regards!

Moisture barrier works
This product is amazing!!! We had used it before on our trawler under the mattresses, sofas, it works to keep everything dry and mold free. We now have put it in our RV under the beds and sofas....... we live in FL and lots of humidity...... we NEED this product!!! You wont be disappointed !!!

Wonderful product
I use this under my dog's mattress in his kennel, as well as beneath one of my memory foam mattresses that is supported by a sheet of plywood instead of the typical slats that support a mattress. The ability for air to flow beneath memory foam is important, particularly the dog bed. The aire-flow moisture barrier hasn't just prevented moisture from forming beneath the mattress, but has prevented unpleasant aromas from forming in the kennel as well.

We have had moisture issues with our mattresses in our Airstream and even mold even while the coach was heated. Aire-flow has completely eliminated this problem and I ordered another piece to insert behind our couch which touches the outside wall and creates moisture. I’m confident I won’t have that problem any longer there either. Excellent product.

Solved a thorny problem
We had some moisture and minor mold problems with the previous foam mattress in our RV. We found the replacement mattress we wanted but wanted to make sure we didn't have the same problems again. Aire-Flow saved me from having to do extensive modifications to our bed platform and/or design and build a slat system. The only reason I didn't give the product a fifth star is the price... a bit costly in my opinion.

used in RV
I purchased this to use in our airstream between the mattress and the wood platform it lays on to reduce moisture. The material is of good quality for this purpose and it seem like it will do a good job. So far it is working fine but havent had it installed long enough to really tell. It was received quick and packaged nicely.

A worthwhile investment to prevent a costly problem
The Aire-Fliw moisture barrier arrived on time as promised and the size was as ordered. Installation was easy. There is absolutely no difference in the comfort of our travel trailer bed. It will provide air flow as intended.

Excellent for tent railer
Our new pop up tent trailer developed moisture on the the front bunk, which has a reflective insulated bottom. The Aire-Flow moisture Barriers add a perfect layer of ventilation to prevent the moisture from collecting under the mattress. Easy to cut. Easy to place. Still closes up secure in the down position.
