How Do I Keep Fragrance Consistent Across Clinics With Different Sizes and AC Systems?

By accepting that consistency is a maintained condition rather than a delivered one. The size and air-conditioning differences are real and they matter, but they are the easy half: a branch of 900 sq ft on wall-mounted splits and one of 2,400 sq ft on ducted central AC will simply need different numbers, and once you have set both correctly they read the same at the door. That part takes an afternoon. The hard half is that both of those settings will be wrong within a year unless somebody checks them, and they will be wrong in the same direction. Levels creep upward. Always upward, never down. The mechanism is not carelessness, it is ordinary human olfaction: everyone in the building stops registering a constant smell within about twenty minutes, so by mid-morning the front desk genuinely cannot smell the reception. Eventually someone says it does not smell of anything any more, the dial goes up a step, and nobody ever proposes the opposite - because no person who has been sitting in a room all day has ever thought it smelled too strong. Repeat that three times over a year, in one branch and not the others, and you have a chain that is inconsistent for reasons no one can reconstruct. So the method is: set once, record, lock, and audit on foot. Set each branch in its own building by walking in from outside after at least twenty minutes away, choosing the lowest level at which you notice a clean room rather than a fragrance. Write the setting, the machine position, the run hours, the date and the name of whoever set it onto a one-page branch sheet. Engage the key-lock on the SOSA Vaayu at ₹11,999, or on the equivalent machine at a smaller site, so that changing it becomes a deliberate act rather than a passing one. Then once a quarter, one named person arrives at each branch unannounced, from outside, at roughly the same time of day, and answers two questions: can I name the fragrance, and has it gone by the time I reach the desk. If they can name it, the branch is too strong regardless of what the sheet says. Check the dial against the sheet at the same time; a discrepancy is the finding, not the smell. The honest concession is that the correction is nearly always downward, and the cheapest improvement available to any chain is to take every branch down one step and see whether a single person mentions it. Under about 750 sq ft, the machine is a SOSA Sukoon at ₹1,899, and the audit is identical. The standing limits do not vary between branches: no clinical or therapeutic claim, fragrance alongside cleaning and ventilation and never used to cover another smell, and procedure, recovery and photography rooms unscented everywhere. Ask for a clinic scenting plan and send the branch list.
