Nordic Home Case Studies

Real examples of homes that successfully improved indoor air quality using natural methods in cold climate conditions.

Case Study 1: Small Apartment in Helsinki

Before air quality improvements

Before

  • Sealed windows, minimal ventilation
  • Low humidity levels (25-30%)
  • Dust accumulation on surfaces
  • Stale air feeling
  • No plants or natural elements
After air quality improvements

After

  • Strategic plant placement (8 air-purifying plants)
  • Humidity increased to 40-45% naturally
  • Daily brief ventilation routine
  • Beeswax candles in main living area
  • Natural fabric textiles throughout

Results

Within three months, residents reported improved breathing comfort, reduced dust accumulation, and a fresher indoor atmosphere. The natural approach required minimal maintenance and created a more pleasant living environment.

Case Study 2: Wooden Cottage in Lapland

Before natural air solutions

Before

  • Wood stove drying air significantly
  • Limited natural light
  • Poor air circulation in corners
  • High particulate matter from heating
  • Cold drafts affecting comfort
After natural air solutions

After

  • Water features near heat source
  • Salt lamps in key areas
  • Improved airflow patterns
  • Natural humidification methods
  • Strategic plant placement for filtration

Results

The combination of natural humidification and air-purifying plants significantly improved air quality. Residents noticed reduced dryness, better breathing comfort, and a more balanced indoor environment despite the wood heating system.

Case Study 3: Modern Eco-Home in Turku

Before eco improvements

Before

  • Modern sealed construction
  • Mechanical ventilation only
  • Synthetic materials throughout
  • No natural air purification
  • Energy-intensive systems
After eco improvements

After

  • Comprehensive plant system (15+ plants)
  • Natural fabric replacements
  • Essential oil ventilation strategy
  • Low-energy humidification
  • Combined natural and mechanical systems

Results

The integration of natural methods with existing systems created optimal air quality while reducing energy consumption. The home now maintains excellent air quality with lower operational costs and a more natural living environment.
