Allergen Proof Covers For Mattresses And Pillows Buying Guide for 2026

When shopping for allergen proof covers for mattresses and pillows, there are several critical features to consider. Below we break down the most important criteria to help you make an informed decision. Each factor directly impacts the cover’s effectiveness, comfort, and durability.

Material and Breathability

The fabric of an allergen proof cover determines both comfort and protection. Cotton terry tops, like those used in the adjustable mattress options, offer excellent breathability and moisture wicking. Polyester blends with a waterproof backing are common, but they can sometimes trap heat. Look for covers that balance softness with a tight weave to block particles while still allowing air circulation.

For pillow covers, a smooth, noiseless fabric is essential to avoid rustling during sleep. Many premium covers use a cotton surface on one side and a polyurethane coating on the others, providing both comfort and protection. Always check the fabric composition to ensure it meets your comfort preferences.

Waterproofing

Waterproof layers are a common feature in mattress encasements, protecting against spills, sweat, and accidents. However, not all waterproof membranes are created equal. Some may feel plasticky or trap heat. The SureGuard Mattress Encasement uses a 100% waterproof backing that is also breathable, while the AllerEase models incorporate a quiet, flexible waterproof layer. If you need protection for bedwetting or pets, prioritize a cover with a reliable waterproof rating.

Remember that waterproof covers should still be machine washable. Check care instructions to ensure easy maintenance. A good rule of thumb is to wash every two months for general protection, or monthly for allergy sufferers.

Bed Bug Protection

Bed bugs are a growing concern, and an encasement that completely seals your mattress can prevent infestations. Look for features like a zippered closure with a fine mesh that prevents even the smallest bugs from entering or escaping. The SureGuard model uses Invisi-Zip and SureSeal technology for a secure seal. A six-sided encasement is essential for full protection, as it covers the top, sides, and bottom of the mattress.

For pillows, a zippered cover that fully encloses the pillow is equally important. Many allergen proof pillow covers also claim bed bug protection, but verify that the zipper track is sealed to prevent escape.

Fit and Depth

A proper fit is crucial for both comfort and protection. Mattress depths vary widely, from standard 8-inch to extra-deep 16-inch models. The covers we reviewed accommodate different depths: the SureGuard fits 13-16 inches, while the AllerEase Maximum fits up to 15 inches for queen and king sizes. Always measure your mattress before purchasing to ensure a snug fit. A loose cover can shift and expose your mattress to allergens.

Pillow covers typically come in standard sizes (queen, king, standard). Ensure you choose the correct size for your pillows to maintain a smooth, wrinkle-free surface.

Ease of Cleaning

Allergen proof covers need regular washing to remain effective. Machine washable covers are a must. Most of our recommended products can be washed in hot water and tumble dried on low. The AllerEase models are particularly easy to care for, with instructions for non-chlorine bleach when needed. A zippered encasement should be unzipped before washing to allow water to circulate inside. Check the warranty: a longer warranty often indicates higher durability.

Allergen Blocking Effectiveness

The primary purpose of these covers is to block allergens. Look for products that are independently tested and certified, such as GREENGUARD Gold certification for low chemical emissions. The SureGuard Mattress Encasement holds this certification. Tightly woven fabrics can prevent 99.9% of dust mites, pollen, and pet dander from passing through. Some covers also feature antimicrobial treatments to inhibit mold and mildew growth.

For maximum protection, consider using both a mattress encasement and a pillow cover from the same brand to ensure consistent quality. Pairing with a box spring encasement can further reduce allergen exposure.
