To answer the second half of your question, you can pick up one of these to measure CO2 level (1). Some specific things to check would be the kitchen while cooking, or the bedroom overnight. If you live in a moderate climate, rather than an HEV, you can likely get away with just running bathroom exhaust fans for a portion of the day; you can get switches that will do this automatically. 1: https://www.amazon.com/Hydrofarm-Autopilot-Desktop-Monitor-L... |
