A clinic visit runs 2–3 hours door to door: drive, park, wait, session, drive back. A home session is 60–90 minutes, and the chamber is in your house—you can read, work on a laptop, or nap.
Going to a clinic takes 2–3 hours when you add up driving, waiting, and the session. At home it's 60–90 minutes, and you can read or work inside the chamber.
At 200 sessions/year (a standard 5x/week protocol), clinic visits consume 400–600 hours of transit—that's 10–15 full work weeks.
At $50/hour opportunity cost, that's $20–30K/year the dollar math doesn't show.
