It is impossible to eliminate all allergens from your surrounding environment. However, it is possible to reduce potential allergens in your home. The primary allergens include pollen, dust, mold, and cat dander. Porous objects within the home can harbor allergens. Fabric curtains, drapes, and shades are some of the worst window treatments for allergy sufferers.
Solid surface window coverings are the optimum treatment. Interior shutters have no soft surfaces and can be wiped clean easily.
