Mark committed to blowing out his entire shop every Friday. Garage door open, start from the back wall, work toward the door. 15 minutes.
Day 3: The evening cough didn't come. Lisa noticed before he did. She looked at him across the dinner table and said, "You didn't cough once." Mark hadn't even realized.
Day 7: Mark spent four hours in the shop on Saturday building a cherry end table. Came upstairs. No cough. No throat irritation. No gritty feeling in his nose. He walked Lisa down to the garage to show her the rafters. She ran her finger across the top of the table saw. Clean. "She looked at me like I'd renovated the place," Mark laughed. "She said, 'It smells different in here.' She was right. It smelled like wood — not like dust."
Day 14: His particle counter showed ambient PM2.5 was 54% lower during active cutting than his previous baseline.
At his 8-week follow-up, Dr. Patel ran a pulmonary function test. Mark's lung capacity had improved by 11% — not because the scarring reversed, but because his lungs weren't being assaulted by new particles every day.
"Whatever you changed in that shop," Dr. Patel told him, "don't stop."
Mark hasn't stopped. Every Friday. Fifteen minutes. Same routine. His buddy Greg saw the clean shop and borrowed the Seese Pro "just to try it." Mark got it back three weeks later — with a thank-you six-pack and the words: "Where has this been my whole life?"
"I spent $2,000 on dust collection and air filtration that left the most dangerous dust untouched," Mark told me. "Then I spent $120 on the thing that actually removed it. I wish I'd found it 14 years ago."
