Efficacy in allergen control and air permeability of different materials used for bed encasement.
BACKGROUND
Different types of textile are used for the preparation of covers for bed encasement. The aim of the present study was to evaluate different fabrics employed for mattress covers regarding their efficacy in blocking Der p 1 and Fel d 1 as well as their air permeability.


METHODS
Eleven different commercially available fabrics manufactured for allergen avoidance have been tested and compared with regular cotton. Dust samples titered for Der p 1 and Fel d 1 were pulled through the different fabrics using a modified Fussnecker dust trap and collected by a filter located downstream. Airflow through the dust trap was controlled by a vacuum pump operating for 5 min and measured at the beginning (T0) and at the end (T1) of the test.


RESULTS
All the tightly woven and laminated materials were able to control mite allergen permeability allowing air passage but they significantly differed in Fel d 1 permeability. Laminated tissues and laminated tissue not tissued were effective in controlling both the allergens but they did not allow air permeability.


CONCLUSIONS
Detailed knowledge about the actual properties of the products for bed encasement needs to be considered in order to optimize allergen avoidance, disease control and sleep comfort.
