Karen used the Seese Pro every three days for the first two weeks. Open windows, start from the back rooms, work toward the front door. Twenty minutes each time.
Day 3: Ethan slept through the night for the first time in two months.
Day 7: No coughing. No wheezing. Karen checked on him at 2 a.m. out of habit. He was sleeping on his side, breathing quietly.
Day 14: Karen called Dr. Chen's office. "I don't know if this is a coincidence," she said, "but Ethan hasn't had a single episode since I started using this thing."
It wasn't a coincidence.
At his six-week checkup, Dr. Chen ran a follow-up air quality assessment in Ethan's bedroom. The dust mite allergen concentration had dropped by over 60%.
"Whatever you're doing," Dr. Chen told her, "keep doing it."
Karen keeps doing it. Every three days. Twenty minutes. The same device, the same routine, the same open windows.
"I spent $1,200 on cleaning tools that made my son's room worse," Karen told me. "Then I spent $120 on a tool that fixed it. I will never not own one of these. Ever."
