I checked with her in the middle of the four weeks to see how things were going. She said that she bought the air purifier and also did the other things that the doctor had suggested for her grandson. Her husband’s allergies have been very good when he is at home. He has problems with a running nose and watering eyes while he is at employment, but within an hour of getting home his symptoms are past absent. This has greatly cut down on the medications that he has to take. She is glad that she bought the mattress cover and pillow cases. Her grandson is more comfortable when in his controlled environment at home with the help of Portable Hepa Air Cleaner.
