My father loves to have the windows open to let the fresh air into the house. But, my mother is an allergy sufferer and bringing the fresh air inside makes her nose stuffy and causes her to sneeze. I can’t wait to tell them that now there is a way for them to experience fresh air inside without opening up all of the doors and windows. The Alen BreatheSmart purifies the air inside the home leaving it crisp and clean for Dad and eliminating allergens that give Mom itchy eyes and nose. This may be the best thing to happen in their marriage since the Beach Boys 50th Reunion tour!
