Review: Works for me! - My allergist recommended dust mite covers for our duvet, pillows & mattress as a first step in reducing my allergy symptoms. I was looking for a light weight, non-crinkly fabric & an easy to use duvet cover. Other reviewers mentioned that this product had these attributes, & I am happy to agree. Another nice feature is that each inside corner has ties for securing your comforter or blanket to keep it from shifting inside the cover. The fabric is a nice crisp white & is nice enough to use without a duvet cover if you like a plain white bed. It is also very wrinkle resistant & has a nearly full-length zipper which is very helpful. I also purchased the pillow covers, which I have reviewed separately, from the same manufacturer. I am very pleased with both & feel they were a worthwhile investment to minimize my allergy symptoms.
Review: Excellent! - I purchased two of these pillow covers and the duvet cover which is also made by Allersoft. Both are lovely, excellent quality. I will be purchasing more of these for the rest of the household pillows. Recently, I was reminded of how gross dust mites can bee to the beds and pillows. It's one of those things that people hear over the years and might try to ignore (I have in the past). Something triggered in me this time, though, and I was on a mission to seal all of the items we sleep on. I did not want to get rid of my favorite feather/down pillows but couldn't stand the thought of what is in them after 10 years. I took a chance and washed them in my front loading washing machine on the sanitize cycle, extra hot water, with bleach, 3 times each (my husband was shaking his head a lot through this whole process). I figured if they didn't fall apart, we were good for another ten years! I dried them in the dryer with a few tennis balls. Then, placed them outside on a non-humid, dry, sunny day in the sun for a few hours. I then encased them in two of these covers. And, I will be purchasing an additional duvet cover to go over the top of the other duvet cover. I purchased the Allersoft duvet as a protectant layer/dust mite barrier for the down comforter and then was going to purchase some other duvet topper. But I like the look of the white duvet so much (and it is really great quality), I thought I will keep all the bed linens white. When I started looking for just a plain white duvet cover to go over the Allersoft layer, they were just as much or more for what I am sure would be a lesser quality (duvet was around $75 for king size). I know it sounds a little excess, but, by covering the allergy layer with another white, Allersoft cover, I can wash that additional layer as much as I want without worrying about degrading the fabric. The care instructions state to only wash twice a year which with those instructions and reviews elsewhere leads me to believe that the tight weave of this fabric, which is what makes it the allergen barrier, could start to loosen up after repeated washings. I am extremely happy these are 100% cotton and made in the USA.

### ⭐⭐⭐⭐ Fantastic but tad thin
*by L***3 on November 23, 2011*

LOVE THIS! I would have given it 5 stars if it was a little cheaper. I paid $74 frm Amazon. PROS: - It's 100% cotton (no crinkly polyprop) with that awesome crisp feel. - Long zipper (vs buttons so your duvet doesn't hang out) - corner ties inside to keep duvet in place - Feather-proof. Especially obvious when I unzip the cover - feathers + dust flies around. - I don't have severe allergies, but it's working great for me. You can tell it has a tight weave. - extremely light-weight. CONS: - Thin. So thin you can see the color of my duvet (which is cream). Not a huge con in my book. In fact, thinking of getting another one because I love this one so much. One as a protector and 2nd one as a duvet cover that gets removed + washed. I think that will take care of the see-through factor. Wish it was slighter cheaper considering how thin it is... That's the only reason I took a star off. - Quite wrinkly out of the dryer. But I like my sheets kinda wrinkly. Makes the bed look cozy. Hope this review was helpful. They drive my decisions, so I've decided to review my purchases from now on.
