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 Hypervent Aire-Flow™ Mattress Underlay.  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 Hypervent Aire-Flowresolve my issue?

 

Hypervent 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, the Hypervent Aire-Flow™ material allows that moisture to evaporate.

 

What is Hypervent 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.  

 

Features:

  • 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

Dimensions:

Hypervent Aire-Flow™ is available in widths of 40" 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.

The Hypervent Aire-Flow™ 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.  

Non-Contiguous States & Canada Shipping: If shipping to Alaska, Hawaii, US Territories, or Canada, please call for shipping costs. Remote areas may be assessed higher shipping fees. The customer is responsible for all customs fees when shipping to Canada.

A shopper on Oct 6, 2018
BEST ANSWER: No. I have a very good (thick) memory foam mattress on top of it and the only time I even notice it is when I change the sheets. And even though we've had a very moist summer, there is no sign of mold or mildew!
Does it have an off gassing smell?
A shopper on Feb 19, 2019
BEST ANSWER: The Hypervent Moisture Barrier does not have an off gassing smell. Also, all of our mattress are made in the USA, with USA made components. Nothing is outsourced. Our mattresses do not have an off gas smell, they are Certipurus certified:

What about between the mattress and the smooth side of this material? The aire-flow material provides airflow between mattress and floor, but none between the material and the mattress itself... Won't mildew develop there??
Debi C on Feb 2, 2019
BEST ANSWER: We’ve had ours for 18 months and we haven’t had any issues with mildew or moisture between the material and the mattress. We have had moisture between the plastic part and the bed frame and the barrier has worked as intended, preventing that moisture from reaching our mattress.
How long does it take to get it?

how thick is Aire- flow?
e b on Nov 21, 2018
BEST ANSWER: I think it's about a half inch, although I haven't measured it.
How do you put it under a mattress that is already there?
Shirley R on Oct 14, 2018
BEST ANSWER: Aire-flow is a layer about 1 inch thick that goes between the bed frame and the mattress. If you cannot separate the mattress from the frame I do not think this will work for you.
We are having a problem with tape (duct, vent, etc) not sticking to the fabric of our Aire-Flow sections. What adhesive is advisable?
Thanks
A shopper on Oct 19, 2018
BEST ANSWER: Hello! If you are unable to find a strong enough industrial tape I would recommend an adhesive putty that some other users have had success with. Here is a link to it: https://www.officedepot.com/a/products/836319/DAP-BlueStik-Reusable-Adhesive-Putty-1/?cm_mmc=PLA-_-Google-_-Tape_Adhesives-_-836319&gclid=EAIaIQobChMIssPlwryT3gIVBoVpCh0tsAWVEAkYASABEgLEM_D_BwE&gclsrc=aw.ds
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!

Can? you lay this between 2 mattress for protection of mold I purchased a bunkie board to go under my new mattress cause it sag in the middle I like to use this between mattresses to keep each mattress safe from mold
Babygirl on Feb 27, 2019
BEST ANSWER: Hello Marilyn,
Thank you for your interest in Mattress Insider! The Hypervent Aire-Flow Moisture Barrier is made to sit on a solid surface, under the mattress, to help avoid condensation developing. It is not recommended to place this item between two mattresses as this will not allow airflow. We would also never recommend placing one mattress on top of another. If your mattress is sagging, the mattress placed on top of it will also create that same sagging issue over time. Please feel free to contact us with any further questions.
Kind Regards!

Mattress measures 6ft l x 5ft w how many would o need?
Laura E on Nov 27, 2018
BEST ANSWER: Hello Laura,
You would need a total of 10 ft. You would cut it in 2 - 5 ft pieces and place them side to side across the width of the mattress. This would leave an extra amount of 6 inches to trim at the foot.
Kind Regards!

I just ordered 8 feet (8' x 39") for my RV. The length beyond 80" will be for the head of my queen mattress that rests against an outer wall to prevent frost. It is not the full width of my queen mattress. Has anyone else done it this way? I've read it isn't necessary to cover the full width. It is just me and my Weimaraner in bed at night.
A shopper on Nov 9, 2018
BEST ANSWER: Hello,
We do suggest covering the full space under your mattress because anywhere that the mattress touches the platform, when not allowed for airflow, can develop condensation and possibly mold / mildew. To cover the whole surface of a 60 x 80" space, you would need 10' total (2 - 5' pieces placed across the width of the platform and taped together in the middle).
Kind Regards!
Hi. I have a basic twin sleeper chair which has a foam mattress resting on a solid fabric type structure. We noticed in one of the two beds that we have what could be a mold/mildew situation starting. We have cleaned it and the chair/bed is now actually been moved to another residence (daughters apartment). See it happening again. It is used for occasional overnight purposes. Would this product be helpful in this situation? And can it be malleable to fold up when the mattress pull out is converted back to seating?
Debbie B on Nov 4, 2018
BEST ANSWER: HI Debbie,
Yes, the Aire-Flow Moisture Barrier will help avoid any further condensation, therefor avoiding mold & mildew build-up. You may need to cut the mat in to 3 separate pieces to fit your frame so it will fold correctly in to the sleeper chair.
Kind Regards!

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
BEST ANSWER: Hi Derek,
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!

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.

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.
