Its breathable microfiber fabric offers silky softness without trapping heat, while an extra-long zipper with an interior flap ensures easy installation and allergen containment. Made in the USA with superior sewing construction and backed by a lifetime warranty, this encasing is the trusted choice for allergy sufferers seeking comfort, durability, and total protection. ## Description MISSION: ALLERGY Premium Microfiber Fabric is the ultimate allergen-barrier: totally effective, silky soft, and imperceptible beneath the sheets. It is extremely tightly woven, with a mean pore size of 2 microns to block all allergens, yet is air-permeable, making it completely comfortable to sleep on. It is not hot and sweaty, as are encasing fabrics made with membranes; does not allow any allergen escape, as do many cotton encasings; and does not accumulate surface allergen, as do encasings made with terry cloth or non-woven fabric. MISSION: ALLERGY Allergen-Proof Mattress Encasings are manufactured with the highest quality sewing construction. All seams and edges are bound for durability. Placement of encasings on the mattress is easier, thanks to super-long zippers that are half the circumference of the entire mattress! Zippers are of the highest quality, with an interior zipper flap to prevent allergen escape through the zipper webbing (no tape needed). These medical-grade encasings are suitable for adults or children with allergic asthma, rhinitis, or eczema (or simply for good hygiene). They are the ultimate allergen-proof mattress encasing for comfort, protection, and durability. 100% Woven Polyester Microfiber. Lifetime warranty. “… protect both your pillows and your mattress with special mite-proof covers, experts say.

The fix is to use hypoallergenic encasements on my mattress and pillows. Dr. Fost recommends Mission: Allergy.” HEALTH MAGAZINE "How healthy is your bedroom?" “…The first step in your mite-control mission: the right pillow and mattress covers. Skip the cheapie versions—their weave isn't tight enough. Instead, invest in Mission: Allergy Premium Microfiber Allergen-Proof Encasings.” MEN'S HEALTH MAGAZINE "Clearing the Air on Allergies" Review: As advertised - Nice product - good fit Review: Easy to slide onto deep mattresses - Just put them on brand new mattress, so too soon to see how they help with allergies.

Our mattress is so big and heavy.** A: No it does not zip all the way down-it's about half way. You don't need to wash it often though. **Q: Where is the zipper on this cover? The sides or ends? I have an air mattress with hoses coming out at the head. Would this cover work?** A: Reply from Seller: The zipper extends around half of both sides and the foot of the encasing. It is not conducive for use with hoses. A ”Fitted” encasing is used for this purpose. It has no bottom to it and the sides tuck around the hoses and under the mattress, like a fitted sheet. The”Fitted” encasing fits multiple depth mattresses, 9”-18” depths. It has been tested to block all allergen.

We've been using ours for three years and like it. **Q: I have a 12 inch mattress but another inch and a half pillow top temperoedic. 12 or 15? Thanks!** A: I decided to get a separate cover for the Topper alone because the Topper should be turned and rotated during the year. Putting both items in the encasing would make this very difficult. I also got a separate encasing for the mattress itself, separate from the topper. ## Customer Reviews ### ⭐⭐⭐⭐⭐ As advertised *by G***N on 20 February 2026* Nice product - good fit ### ⭐⭐⭐⭐⭐ Easy to slide onto deep mattresses *by S***. on 28 May 2020* Just put them on brand new mattress, so too soon to see how they help with allergies.
