Anti-mite material is made by 5 desirable properties:

  • REGULAR Pattern
  • LIMITED Mite Penetration
  • TIGHTLY WOVEN Microfiber

MITE penetration / colonization was observed in non-tightly woven and non-woven fabric.

Mites within the fibers of a laminate-coated and loosely
woven cover (A; 3100 magnification, scanning electron microscope)
Evidence of molting among nonwoven fibers (B; 3200 magnification, scanning electron microscope)
Dead mites on an acaricide-coated and nonwoven cover (C; 340 magnification, stereomicroscope)
a group of mites in the matrix of a non-woven cover (D; 375 magnification

Study Design: A study of 32 covers collected from 9 different countries, to evaluate the effectiveness of mite penetration every day for 1 week under a stereomicroscope.

NO MITE penetration was observed in tightly woven fabric.
