Extended podcast transcript (2026-01-21) where Michael interviews Sabin Preda (Novinger) about correct home airing and modern ventilation. Adds practical behavioral guidance: radiators do not remove absolute humidity (they lower relative humidity by raising temperature); lower indoor temperature (e.g., 20–22 °C or even 17–18 °C in bedrooms) raises relative humidity toward comfortable ~50%. Misconfigured ventilation units (bypass behavior) can admit cold outdoor air if thermostat setpoints differ from actual indoor use. Avoid aerosolized fragranced products (sprays, scented candles) because they emit VOCs and particulates; sprays should be used near windows or applied as roll-on. Open flames (candles, small fireplaces, gas hobs) raise CO2 — observed fireplace cases reached ~1,000–1,200 ppm CO2. Kitchen hoods commonly move ~400–600 m3/h and should be used with a compensating open window. Humidifiers carry legionella risk if water stagnates; ducted (networked) humidifiers with fresh water feed and anti-legionella filters are safer for central systems. Novinger provides educational materials on YouTube/TikTok, a showroom in Chiajna (near Bucharest), and contact via their website. Reinforces prior recommendations: use CO2 sensors (range to 5k–10k ppm), maintain 40–60% RH, prefer whole-house ventilation with proper filters (e.g., F7) and regular commissioning/servicing.

Questions this episode answers

17–18 °C (examples cited for better sleep); also suggested 20–22 °C as comfortable indoor targets.

Approximately 1,000–1,200 ppm (reported in a vacation-home example).

About 400–600 m3/hour (advised to use hood and open a compensating window).

Risk of Legionella and microbial growth from stagnant water if the unit is not cleaned regularly.
