Organic Cotton Dust Mite Mattress Cover

Lowest prices. GOTS Certified Organic. And FREE Shipping!

Our 100% Certified Organic Cotton Dust Mite Mattress Cover Protects from Allergens, Dust Mites and Bedbugs.

This GOTS certified Organic Cotton Dust Mite Mattress Cover is the most natural, non-toxic product available for dust mite allergy prevention. This soft certified organic cotton fabric is more comfortable than other allergy dust mite covers. There is no plastic membrane and absolutely NO chemical treatments added to these pure 100% organic cotton covers. No formaldehyde, no antimicrobials, no fire retardants, no bleach!

This uniquely designed, organic cotton dust mite mattress cover uses an allergy cloth shields to protect your mattress and pillows from pet dander, dust mites, bed bugs and other harmful allergens. It is tightly woven in a special overlap process. The organic cotton cloth is woven so tightly that allergens cannot penetrate it.

Pore size less than 5 microns for best dust mite and allergen protection and a breathable, comfortable fabric!

Lab Tested and Certified

With a mean flow pore size diameter of 4.91 microns, this fabric is one of the most effective barriers against pet dander, dust mites, bed bugs, and other harmful allergens.

Pore size is the diameter of the space or hole between the threads. The average waste particle of dust mites is approximately 9 microns so the pore size must be less than 9. Typically, any fabric with a pore size less than 6 or 7 will block all allergens including pet dander. Anything below 5 microns is premium and the difference between 5 microns and 2 microns is not relevant. Both will equally block all allergens, including cat allergen. A very low pore size (1 or 2 microns) gives you low air flow, which will make the fabric hot to sleep on.

Remember that thread count in an organic cotton dust mite mattress cover has nothing to do with pore size. 1000 count sheets for example have more threads per square inch but the pore size is not maintained. Thus, these sheet fabrics will do nothing to encase the allergens.

BugShield Zipper system!

These organic cotton dust mite mattress covers are made with the BugShield Zipper System designed to give you extra bed bug protection from an accidental opening once you have closed the zipper. This system provides added security if exposed to bed bugs.

You can learn more about the importance of dust mite mattress covers at the Asthma and Allergy Foundation of America’s page on dust mite treatment and prevention.

Sizes and Prices

NOTE: It’s important to order a cover thickness a little larger than your mattress so it will be easy to go on and off. It’s better to have a cover a little too large than one that is too small. You can tuck any extra material underneath the mattress and never notice it’s there. 12″ depth will fit 12″ thick mattress (same with other sizes). If in doubt, order larger cover.

    I find enormous comfort in using an organic cotton cover on my children’s beds. This product is easy to use, soft, and durable.

    Lisa G.:

    I bought the twin zippered cover for my daughter’s bed because she suffers from allergies. A zippered mattress cover is a must for allergy suffers (and a good idea for the rest of us) but I didn’t want to buy a convention cotton cover because fungicides and pesticides are often used to produce cotton and she’s spending 8 hours of her day on this bed. I also didn’t want to go broke buying organic. This cover solved both my problems. The price is very good. It’s very well made. I washed it in super hot water and it held up just fine and didn’t shrink. Customer service was ridiculously nice as I had a ton of questions. I’m now going to buy this cover for the rest of my family.
