Hunter Douglas, maker of Luxaflex blinds, has formulated the Sanitized treatment, which is ideal for your purposes. "This in-built technology gives protection against dust mites, odours, mould and mildew," says Genevieve Marshall, Marketing Manager of Hunter Douglas.

"The latest Luxaflex fabrics, Portobello and Caspien, both have this technology. They're also treated with Duraguard, a process that protects the fabric from absorbing household stains."

In addition, they emit low levels of VOCs (volatile organic compounds), offering extra protection for allergy sufferers. These fabrics can be made up in various styles, including roller blinds, roman blinds and panel glide blinds. Luxaflex; 135 892.
