Our mattress is like a large sponge absorbing everything. However, unlike household sponges we cannot run it in hot water to clean and after, let it air dry fast enough to use again. This makes our mattress vulnerable to anything.
I discovered my allergies merely by accident. I bought pillow protectors merely to keep my pillow clean longer but did not realize this was also an end to my constant health problems.
I did not know about Indoor allergies like: pet dander, mold, dust, dust mites. Commonly embed themselves in carpet and other fabric. Additionally, there are Outdoor allergies that we bring into the home: tree pollen etc.
After my discovery, I researched and developed full mattress covers and pillow protectors sold through my company Care Aid Plus so you and your family can enjoy the same healthy nights and days.
