Pella® Technology Helps with Allergen Reduction in Your Home Pella between-the-glass technology doesn’t only offer low-maintenance cleaning, it also sparks allergen reduction and keeps healthier air inside your Roanoke home. Based on statistics furnished by WebMD.com, allergies impacts 1 out of 5 people in the U.S., and allergies are ranked 5th among the leading chronic diseases. The annual cost that treating allergy sufferers adds to the U.S. health care system is almost $8 billion. Nearly 4 million workdays are lost due to allergies, such as hay fever. Amazingly, more than 90% of our lifetime is spent indoors. Because we are a country of animal lovers (over 62% of households include a dog or cat), indoor pollution surpasses outdoor pollution by as much as 100 times, depending upon whether the resident smokes. Ordinary roomside blinds collect 10 times more of certain airborne allergens than Designer Series® windows with between-the-glass blinds1. Pella’s between-the-glass blinds or fabric shades are shielded from dust, pet dander, mold spores and messes, but they still provide the protection from light that you want with an easy-to-operate switch.
