Made from tightly woven, breathable microfiber polyester, it blocks 100% of dust mites and animal dander while maintaining comfort. Featuring premium bound seams, an interior zipper flap, and a 10-year warranty, this USA-made encasing offers durable, clinically tested protection ideal for allergy sufferers and anyone seeking superior hygiene. ## Description MISSION: ALLERGY Barrier II Fabric is the most cost-effective allergen-barrier: allergen-impermeable, soft, and lightweight. It is extremely tightly woven, with a mean pore size of 6 microns to block all allergens, yet is breathable (air-permeable), making it very 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 Boxspring Encasings are manufactured with the highest quality sewing construction. The differences are immediately apparent. All seams and edges are bound with seam binding for durability. Placement of the encasing on the boxspring is easier, thanks to super-long zippers that are half the circumference of the entire boxspring! 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, allergic rhinitis, or allergic eczema (or simply for good hygiene). They are the ultimate allergen-proof boxspring encasing for comfort, protection, and durability. King and California King sizes are sets of two split sizes. 100% Woven Polyester Microfiber. Ten-year warranty. “… protect both your pillows and your mattress with special mite-proof covers, experts say. Be sure you get covers from a reputable company, like Mission Allergy…” THE NEW YORK TIMES "Much Ado About Dust Mites" 3/4/11 “Say sayonara to dust mites. The fix is to use hypoallergenic encasements on my mattress and pillows. Dr. Fost recommends Mission: Allergy.” HEALTH MAGAZINE "How healthy is your bedroom?" 3/9/11 Review: Quality protector is worth the cost - This mattress protector is soft and thick; not crinkly and susceptible to tearing easily like so many others. Very happy with this purchase. Review: Great for thinner IKEA mattress - I purchased the 4 inch bunkie board cover for my IKEA morgedal twin mattress to help manage allergies. The mattress is 7 inches thick (thought it was closer to 4 or 5). It was a good fit, not perfect and not too loose since this wasn't made for a mattress. Regardless, I'm very pleased with this purchase and would recommend for thinner mattresses. ## Features - MISSION: ALLERGY brand encasings are specifically recommended by leading Allergy Specialists and university Allergy Departments.

Fit is perfect (not too loose/tight). It looks like a clean, decorative cover. I would recommend this to a friend. You don't need to hire an expensive exterminator. Just be logical and take away the bugs' hiding places. Box springs are so insecure. Bed Bugs love them. Use these covers to keep them from go in and out of the box spring. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/753388749-dust-mite-and-allergen-proof-boxspring-encasing-cover-barrier-ii](https://www.desertcart.com.ar/products/753388749-dust-mite-and-allergen-proof-boxspring-encasing-cover-barrier-ii) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-05-22*
