We can't see dust mites/mold, but we can see pinholes and zipper holes.
The size of dust mites is much smaller than what we can see. While sleeping when we squeeze the pillow, dust mites bacteria will escape from the pin whole or zip, and affect our respiratory tract and sleep quality.
The :dc Dustmites Out is designed with 100% sealed, which firmly "Locks" the allergens in the pillow, preventing dust mites and allergies get escaping from the pin whole. After installing the Kemite membrane, put on the bedding pillowcase and use it. It is recommended to change and wash the bedding pillowcase regularly.
The most worrying thing for business travel and hotel accommodation is bedding allergies.
Many people bring their pillowcase in order to prevent allergies. However, the woven structure of the weaving fabric is too large to effectively prevent bacteria and mold infections.
You could put put hotel Pillow directly into :dc Dustmotes Out Protector, and sleep on the pillow protect to avoid pillow direct contact with the skin, which may cause allergies.
