Best Pillow Protector

A pillow protector is a zippered cover that goes on the pillow under your pillowcase. It keeps sweat, oils and dust out of the pillow, and some protectors are made to keep allergens out as well.

This guide covers what health agencies say about dust mites and pillow covers, how protectors differ by fabric, what to check on the zipper and care label, and seventeen protectors to compare.

General information, not medical advice; see a doctor if you have allergy or asthma symptoms that are severe, ongoing or getting worse.

Why Use a Pillow Protector

A protector does two jobs. It keeps the pillow clean, and for people who react to dust mites it adds a barrier around the pillow. The NIEHS says dust mites live in mattresses, bedding and upholstered furniture and can worsen allergies and asthma, and that no home can be made mite-free but the number of mites can be reduced.^[1]

• Dust Mites – The EPA says every home has dust mites, and dust-proof covers on pillows are one of its recommended steps.[2]
• Sweat and Stains – A waterproof protector takes sweat, oil and drool instead of the pillow.
• Washability – A protector goes in the wash far more easily than a pillow.
• Allergens – The NHS names house dust mites among the common allergens and says you can manage an allergy by avoiding what you react to.[5]

---

Materials Compared

• Cotton – A natural fiber that is breathable and washes well. Plain cotton protectors are not waterproof.
• Cotton Terry – Looped cotton with a towel-like surface. It is soft and absorbs moisture.
• Microfiber and Polyester Knit – Smooth, quiet fabrics that stretch. Many have a waterproof backing.
• Bamboo Rayon – The FTC says most soft bamboo fabric is rayon or viscose with no trace of the original plant, and that there is no evidence it is naturally antibacterial.[4]
• Waterproof Backing – TPU, polyurethane or a breathable membrane makes the protector waterproof. A thin layer under a breathable top keeps the pillow dry.

---

Pillow Protector Buying Checks

• Zipper – Pick a protector with a zipper that closes completely. Without one it does not seal the pillow, and a gap lets dust in.
• Bed Bug Claims – Some protectors are sold as bed bug proof. The EPA’s advice on encasements covers mattresses and box springs, and it says to buy a product tested for bed bugs.[3]
• Waterproofing – Choose a breathable top fabric over a waterproof lining so the lining stays away from your skin.
• Size – Match your pillow: Standard is about 20 x 26 inches, and Queen and King are larger.
• Set Size – Check how many protectors come in a set. Several here come in fours.
• Certifications – OEKO-TEX and GREENGUARD Gold are independent labels for materials. They do not make a protector allergy-proof.
• Care – Follow the label, since some protectors dry only on low heat.

For allergy-focused covers, also see our guide to dust mite pillow covers.

Other Steps Against Dust Mites

The NIEHS also advises keeping humidity at or below 50 percent, wiping dust with a damp cloth instead of a dry one and vacuuming with a HEPA filter.^[1] The EPA says to wash bedding in hot water once a week and dry it completely.^[2]

How We Chose These Protectors

These picks come from desk research. We compared product details such as materials, size, care and certifications. We did not test the protectors ourselves.

We looked at these factors:

• Closure – Whether a zipper fully seals the pillow.
• Fabric – Cotton, terry, microfiber, polyester knit or bamboo rayon.
• Waterproofing – Waterproof backing or none.
• Size and Pack – Standard, Queen or King, and number in the set.
• Care – Label washing and drying directions.
