MISSION: ALLERGY® premium quality microfiber mattress encasings are strong, yet lightweight and as soft as silk, totally imperceptible beneath the sheets.

They are made with an extremely tightly woven microfiber fabric with a mean pore size of only 2 microns, the smallest of any commercially available microfiber encasing, which allows the free passage of air and moisture while preventing the escape of all allergens, including dust mite and the smaller animal dander allergens. They are suitable for those with allergic rhinitis, allergic asthma, or eczema (atopic dermatitis)—or simply for good hygiene.

All MISSION: ALLERGY® Allergen-Proof Mattress Encasings are made with the highest level sewing construction. The differences from competitive products are immediately obvious. All seams and edges are bound with seam binding for long-lasting durability. All zippers are of the highest quality and are super long— half the circumference of the entire mattress—making placement of encasing on the mattress easy. Interior zipper flaps prevent the escape of allergen through the zipper webbing.

They are the ultimate allergen-barrier mattress encasings for comfort, allergen protection, and durability. 100% microfiber polyester. Lifetime warranty. Made in USA.

10 years later, still breathing easy
Worth EVERY penny! I have severe dust mite allergies, so my husband and I purchased this when we were first married. 10+ years later and it’s still one of the best purchases we ever made. I love how soft it is, and it’s somehow the perfect texture to keep sheets from slipping and/or clinging too much. Excellent construction, possible to get on the mattress with one person if necessary, and washes well (we follow the instructions carefully). It’s breathable and doesn’t absorb/throw off heat like so many other mattress encasings do. It’s been a fantastic investment in our wellbeing, and we couldn’t recommend it more highly.

Mission allergy has amazing quality products. Made in USA which I love as it supports our country. Made of soft material that's silky. Doesn't make noise when you get on it like cheaper not so good quality encasings, and actually keeps me from having hives and night sweats from dust mites. I can breath soooo much better.

made a big difference
Got this for all the mattresses in the house. First winter without multiple bouts of sinusitis/bronchitis Review by Cal / (Posted on 7/3/2020)
Great Product!!!
Our son needed a quality mattress cover to help him sleep at night and not stay awake from coughing due to his high allergic reaction to dust mites. This mattress cover has been just what he needed! It has worked exactly as we needed it to, and has even helped lessen his dependence on his inhaler. We are so thankful to have had this product recommended to us; and we recommend to anyone who needs a quality cover to fight against dust mites. It was definitely worth the money!

Very happy
Couldn't be better. Review by Barbara / (Posted on 2/11/2020)
Good product, not too thick, fit well
We are happy with the two Long Twin Mattress Encasings. The material is not thick like our last encasing (not your brand) which was 100% cotton--the thinness pleases us! It means the encasing will not tend to bunch up under a sheet and make for uncomfortable sleeping. I am also impressed with the professionalism of your company. My allergist had recommended your company. Review by Beverly / (Posted on 2/7/2020)

The best for your bed.
This is by far the best encasing for your bed. It’s has helped me and my family tremendously and I can’t thank Mission Allergy enough for their products! A bit pricy, but the results are priceless. Review by Christine / (Posted on 12/15/2019)
Very satisfied
I like that it fits perfectly Review by Marie / (Posted on 10/12/2019)
Best mattress casing I have ever had!
Between the mattress pad and a different mattress casing (not from mission:allergy) this encasing has helped by leaps and bounds the most and is by far the best of the 3 I have ever owned (P.S. since purchase it has also helped the most significantly with reducing dust mite allergies, so now I can breathe without need to use an inhaler x3/day!)

These Premium Microfiber products are AMAZING for someone with allergies. I woke up for the first time in ~10 years without feeling like my eyes are burning and itching. I HIGHLY recommend these! I keep telling my friends "Mission Allergy saves lives"! Review by Leanna / (Posted on 7/21/2019)
Mattress cover
This mattress cover is great! It was easy to put I was worried it would be a challenge. I don’t notice it at all, so I’m very pleased with the purchase. Review by Anne / (Posted on 6/18/2019)
Worry-free mattress protection
This encasing went on quite easily, and fit our mattress just right! It's nice to know our mattress is dust-mite free, and also that it doesn't need to be taken off to be washed on a regular basis! Review by Kandia / (Posted on 5/20/2019)
Good Product
It feels good and it fits the bet perfectly. Review by Felix Abadia / (Posted on 5/20/2019)
Works great & surpassed expectations
The mattress cover went over my new 10" memory foam mattress with ease and I am looking forward to it keeping dust mites from me. The materials are great and are thinner than I thought they would be, which is great in order to keep sleeping as cool as possible. I would recommend this product to others. It is a 5 star buy.

Happy with products
I’m very happy with all my purchases. The mattress encasement is a little large for my king mattress but works. I also love the lightweight comforter. I believe they are making a difference. Review by Barbara / (Posted on 4/14/2019)
Sleep better
Great product! Huge difference from encasings at departments stores. My son sleeps better and keeps cool at night. Very satisfied. Review by Ranee / (Posted on 4/8/2019)
Great purchase!
This has been a lifesaver for my 9 mo daughter who was recently diagnosed with allergy to dust mite. I highly recommend this for the littles who have environmental allergies. The fitted sheets easily go over this without issues. Review by Audrey / (Posted on 4/6/2019)

Quality product
Fits well and easy to put on the mattress. Soft, comfortable material that doesn’t make a sound as my son, a very active sleeper, moves about during the night. Hope it helps his dust mite allergy! Review by Adrienne / (Posted on 12/1/2018)
Sleeping better
After I started using this (along with a Mission Allergy comforter, pillow case, and boxspring case) about a month ago, I started sleeping better. Substantially less irritation in my eyes at night. Very thankful to Mission Allergy for making this product. Review by Vijay / (Posted on 11/22/2018)
Immediate results. Wonderful product.
Immediate results. Wonderful project. Review by Glen / (Posted on 11/21/2018)
Really great product that works much better than others!
Mission: Allergy encasings were recommended by my allergist who said they are the best. He was so right. I love these pillow and mattress encasings! I felt the difference the first morning when I could actually breathe. The fabric is soft and comfortable, and I cannot tell there is anything additional on my pillow- no crunchy sound, not hot and sweaty- like some others I've tried. The quality is great and they look like they will last forever. A big thanks to this company for effective products and also for really great customer service!
