Room Ventilation Planner

Build a ventilation routine for the rooms you occupy most, with timings and a carbon dioxide rule, and print it.

This tool gives general information based on the research summarised in What Cooking Puts in Your Air, and What Actually Clears It. It is not a medical device, does not diagnose, and does not replace advice from your clinician.

Free vs Plus




Free (this page)
  • ventilation routine with timings
  • a cue rule with or without a monitor
  • text export and print
  • all citations and cautions


Plus (optional, one-time)
  • calendar (.ics) ventilation reminders
  • unlimited share images
  • share card without the 'Made with CortexLit' footer


Checkout isn't live yet, so Plus is unlocked here with a local code. The check runs in your browser and can be bypassed; it is a placeholder for a real payment link.






Free tier: 1 share image per result.






Commercial disclosure: optional paid Plus tier; all evidence, cautions and the main result are free. No affiliate links, no sponsors.







What this is based on


Every output names at least one verified PubMed source. Identifiers were verified on 2026-10-11 in an earlier batch and carried over into this build; they were not re-queried here, and no retraction database was checked. Verification was at abstract level.

Limits: This schedules ventilation from your own rooms and occupancy; it does not measure your air. The cognitive figures are group averages from a meta-analysis of five studies and one controlled-exposure study.
