My girlfriend and I moved here almost a year ago. I have a rottweiler and she is really allergic to it. At night she is very overworked and always wakes up worse. We also have a small hypoallergenic dog that sleeps on the bed so of course not letting another dog on the bed makes us feel bad even if it aggravates his allergies. We bought RAYCOP hoping it would help get rid of the allergens so we didn't have to wash the duvet cover every few days. RAYCOP is constantly picking up dust and other things that I can't even see on my duvet cover. Her allergies have improved and we are very happy with this purchase!
