How to Choose a Dust Mite Cover

Choosing a dust mite cover that is right for you first requires that the dust mite cover is scientifically certified as 100 percent effective. If any question exists, always ask to see the scientific data. If the data cannot be produced, move on to a brand that practices full disclosure and makes the studies available.

Once you have eliminated all dust mite covers that cannot be proven effective, your choice is simply a matter of comfort and cost. However, always be sure that you are buying zippered covers that totally encase your mattress, box spring, pillows or duvet. If the packaging does not advertise such a feature, it is probably a fitted cover and therefore, worthless.

Another consideration in choosing a dust mite cover is if you require it to be porous. Nonporous dust mite covers can be hot to sleep on because they prevent air from flowing through. However, they are also more than barriers for allergens. They are also barriers for liquids, so they double as spill-proof mattress protectors. If the bed is used by someone who suffers from nighttime incontinence, this is a good choice, but if you tend to sweat a lot in bed, it can be uncomfortable.

Porous dust mite covers are more comfortable than nonporous covers. Most people find cotton to be the most comfortable, but polyester and poly-blend covers hold up better if tend to wash your bedding frequently.

Cotton vs Poly Dust Mite Covers

If you choose a membrane dust mite cover, then the fabric used in the top part of the cover is mostly a matter of comfort. Your choice between cotton, polyester, a blend or another material will usually coincide with your preference for standard bedding. Three top choices for this type of dust mite cover are as follows:

  • Tricot – Tricot is a lightweight, warp-knitted fabric that is made of 100 percent polyester. It is a great choice for those on a budget. On the downside, many consider tricot to be on the scratchy side of the comfort scale.
  • Cotton-poly blend – A blend of cotton and polyester provides for a fabric with more weight and durability. It holds up well with frequent washing, and it is considered more comfortable than tricot.
  • Stretch-knit – Like tricot, stretch-knit is 100 percent polyester, but it is woven in a fashion that gives the fabric a soft and silky feel. Stretch-knit membrane covers combine comfort with the highest level of protection.

If you prefer a non-membrane dust mite cover, your choice will most likely be between 100 percent cotton and 100 percent polyester. The best choice for cotton dust mite covers is a fabric that goes by the brand name Allersoft, but for polyester, you will want to choose the branded fabric known as Pristine.

Allersoft is a highly advanced cotton fabric that boasts pores of less than 5 microns in diameter. Since Allersoft uses no membrane, it is extremely comfortable and does not suffer from deterioration like some membrane covers. Not only is Allersoft the softest type of dust mite cover, but it is also the coolest. It only needs to be washed about once every three to four months. Another benefit of cotton is that it is less expensive than polyester.

Pristine is the brand name of a 100 percent polyester dust mite cover fabric manufactured by Precision Fabrics Group. Because it is a synthetic fabric, it is not as soft as cotton. Pristine has a more slick and slippery feel to it, and it is not as porous. In fact, Pristine has the smallest pore size of any dust mite cover fabric, but the difference in protection is negligible because anything less than 5 microns is more than sufficient. Pristine is more expensive than Allersoft, but it holds up better in the washing machine, so it can be laundered more frequently.

Organic Cotton Dust Mite Covers

Another option in non-membrane dust mite covers is organic cotton. Organic cotton covers are the most expensive type of cover fabric, but they are very helpful for anyone with sensitive skin who needs protection from dust mites. These covers are also recommended for people who suffer from skin conditions, such as psoriasis or eczema.

The difference between standard cotton and organic cotton is that organic cotton fabric is produced without the use of any type of chemicals. While the standard process poses no risk to most people, some people can suffer from a skin reaction from traditional cotton because it is usually died with bleach products.

Where to Buy Dust Mite Covers

Dust mite covers can be purchased at local bedding stores and some drug stores, but to get the best prices on products of the highest quality, it is recommended to turn to the Internet. Online allergy bedding stores specialize in dust mite covers, and they are able to provide the top brands at the most affordable prices. Online dust allergy bedding stores also have the widest selection of fabrics and brands available for sale, for example they have cotton allergy proof mattress covers.


Dust mite covers are an important part of keeping your home free of dust mites and dust mite allergens. For those suffering from severe allergies, it is recommended that old mattresses, box springs, pillows and duvets be replaced with new. This way, the covers can protect your bedding from ever becoming a host for dust mites. No matter your budget or desired comfort level, you will be able to find a quality and effective dust mite cover that will help relieve your allergy symptoms and help prevent them from returning in your own home.
