Dust mite free fabric
Indoor allergy is very often caused by allergies to house dust mites. House dust mites especially live in our beds as they like the warm and humid environment. It is especially the dust mites' excrements that we become allergic to. The symptoms are reminiscent of hay fever or asthma.

In April 2019, we tested our house dust mite density products at the Japanese test center Boken. The purpose of the test was to make sure that dust mites cannot penetrate the fabric of our products. When the house dust mites can't get into your pillow or comforter, they can't put their excrement into the product and it therefore remains naturally hypoallergenic. The test showed that no house dust mites can penetrate our products. We can conclude that our pillow and quilt are woven so tightly that they are free of dust mites.
