Question from liz
Hi Debra,
Thanks for your wonderful site. I am looking for an inexpensive dust-mite barrier for my son’s mattress. Aller-Ease has a mattress cover (the “Original” style) made from polypropylene fabric with a polyethylene film. Do you think that would be safe? I know that you’ve stated that polyethylene is safe and doesn’t off-gas, but what about polypropylene?
If you don’t recommend that one, Aller-Ease also makes a cotton mattress cover. Do you know of any reason why that wouldn’t be safe? (The advantage of the Original is that it is waterproof).
Thank you!
Liz
Debra’s Answer
There is a slight toxicity to polypropylene that polyethylene doesn’t have. If the polyethylene is in the outside, I would say it’s fine.
The cotton one would be better if there is no finish on the cotton.
