There are many options, and it can be confusing to determine the best mattress covers for allergies. I will help you break it down into what is most important to your family.
The best mattress covers for allergies, dust mites, bed bugs, and pet allergens are those that are non-toxic, breathable, and waterproof!
Allergy mattress covers are made to prevent dust mite and bed bug allergens from getting in and out of your mattress. These critters love to crawl into mattresses, and protective covers that can block them out can help with your allergies.
The covers must completely cover the mattress (6 sides) and must have a pore size small enough to block the passage of these small allergens. The pore size is the space between the fibers.
Why is waterproofing so important?
With moisture likely from spills, liquids, sweat, and late-night accidents, it’s important to prevent bacteria and mold, as well as stains, from ruining your mattress. Sleeping on a clean bedding that is free of bacteria and mold is obviously important to your family’s health.
A plastic membrane creates the most effective barrier since nothing can get through the plastic, it is not porous or permeable. For this reason, the plastic makes the cover waterproof and you definitely need to waterproof your children’s beds.
But here’s the problem with plastic covers…
Most plastic covers are made with vinyl/PVC or a type of urethane. Vinyl/PVC contains carcinogens, and the plasticizers used to soften hard PVC plastic and make it flexible enough to use as mattress covers are phthalates or variants of phthalates. Phthalates are a clear health risk; these compounds do not belong in your children’s sleep environment. You can’t even trust “phthalate free” vinyl.
Urethane can be tricky – there are some types that may be safe and others less so.
You don’t want your family to be exposed to harsh chemicals and toxins.
Plastic can be hot to sleep on, not breathable at all. You need airflow between your mattress and the cover. And the plastic can also be wrinkled or crusty, which is the last thing you need when you’re trying to sleep.
Organic Cotton Mattress Covers for Allergies
You can get tightly woven cotton fabric covers with small pores that are considered allergen and dust mite proof. It is better if the cotton is organic if you are going to buy cotton anti-mite covers. Organic cotton dust mite covers are light, cool fabrics that can do the job of blocking out allergens. However, these covers are not waterproof.
You really need waterproof covers for your family if you want to protect the mattress. For this reason, I usually recommend getting organic cotton dust mite covers and adding an organic waterproof mattress topper to cover them. However, buying both the cover and the pad can be a bit expensive.
Now you can get the best of both worlds in a safe, non-toxic, and breathable mattress cover!
Finally we have the best mattress covers for allergies that are effective in blocking out allergens, while being completely waterproof and also safe and non-toxic.
These covers are light, cool and breathable and envelop the entire mattress. The membrane fabric does not allow any allergens to pass through: it protects against pollen, mold spores, animal dander, and even bed bugs and fleas.
The waterproof plastic membrane is non-GMO, bio-based, and derived from corn starch. It is GOTS approved, so we know for sure that it is safe and non-toxic. This membrane is sandwiched between two layers of organic cotton stretch jersey that provides airflow and makes it soft and breathable. There is no creaking, crinkling sound. It is free of all toxins and has 100% waterproof protection that is quiet to sleep on.
