Our White Mountain Textiles Cotton dust mite mattress covers are some of the nicest we have felt and are very reasonably priced. The cotton fabric is soft and lightweight and offers a very small pore size 4.39 micron which is excellent for a woven dust mite cover. A dust mite cover with a small pore size like this is a very efficient barrier to dust mites and their allergens (i.e. broken body parts and feces). One of my favorite things about these mattress covers is they are discrete and quiet, so your family and guests will never know you have dust mite covers on unless they peak under the sheets. A cotton dust mite cover is also very breathable and will not retain excess heat while sleeping. They are easy to wash with durable construction; however, we do not recommend washing more than absolutely necessary due to the fact that woven fabrics loosen with wear and tear which will increase the pore size and reduce their effectiveness. Also, though many times less likely than synthetic covers to cause irritation, these are not organic and could possible cause irritation to those who have multiple chemical sensitivities or super sensitive skin. If you are concerned about possible irritation, it is probably in your favor to spend a little more and purchase our Solus Organic Cotton Dust Mite Covers.

Happy customer.

I purchased this mattress cover because my son has allergies. Very happy with this product. Soft cotton fabric and washes well. Thank you.


It took a long time to get here, but it is just like it was described on the website. Easy to put on the mattress, fits well, great temperature control and very quiet. It was not the cheapest, but at this price is still a great value.


If you are sensitive to chemicals, don't use right out of the package! It smelled unhealthy and had residue/sizing, contrary to an FAQ. Many will not notice, but I have a great sense of smell. It took two wash cycles to remove the mystery fabric additives and have it smell like normal cotton. It's a decent, all cotton fabric. Zipper is solid, not bomb proof. Easy to put on if you have two people. Fit is great. I used a waterproof topper in addition as it's only for dust mites, not stain prevention. After a promotion code, it's was good price. I was happy support this company and not have more money go to Amazon.


Product description was inaccurate, it will not fit a 15" mattress.


I purchased a protector for a European queen-size bed that measures more like 10.25' high. Although the website suggests you size up to a 12", I did not do this and instead bought the . After an initial washing, it fits perfectly -- just the snug way I would want.

I learned because I unfortunately followed the advice of the website for my other American queen, which was about 13", purchasing the 15" size. My mattress absolutely swims in the 15" and I have had to purchase a deep fitted sheet with elastic sides just to keep the 15" protector secured to the mattress. Go with the smaller size!!
