AllergyCare Dust Mite Proof Cotton Encasement
Give your mattress natural, breathable allergy protection with the Bargoose AllergyCare® Cotton Zippered Mattress Encasement. Made from the same 100% cotton allergen-barrier fabric as our AllergyCare® pillow protectors, this fully zippered encasement seals the entire mattress in soft, breathable cotton that helps block dust mites without plastic film, crinkle, or trapped heat.
Why 100% cotton? Most dust-mite mattress covers use a laminated membrane or plastic backing that feels stiff and sleeps hot. AllergyCare® blocks allergens through the tight weave of the cotton itself, so you get a proven barrier with the natural softness and airflow of pure cotton, and nothing laminated to the fabric.
Key features
- Dust mite barrier: Tightly woven 100% cotton helps block dust mites and their allergens from the mattress.
- Quiet and breathable: No plastic film or crinkle, and no added heat retention.
- Complete 360° encasement: Fully zippered on all sides to seal the entire mattress.
- Durable closure: Heavy-gauge nylon zipper with reinforced seams.
- Custom fit: Multiple mattress sizes and depths for a snug fit.
- Machine washable cotton construction.
Independent pore-size testing
This encasement uses the same 100% cotton fabric independently analyzed by Porous Measurement Int'l Group (August 2025), which measured a mean flow pore diameter of 4.62 microns. That tight weave forms the physical barrier that helps block dust mite particles while keeping the cotton breathable. View the pore size analysis report (PDF).
