DIY Air Quality Testing: Understanding Your Home Air Environment

Are you wondering about the air quality in your home? You don’t always need expensive equipment to get valuable insights. Here’s how you can start monitoring your indoor air quality using simple DIY methods.

Visual Inspection

Start with what you can see. Check for visible signs of air quality issues:

- Dust accumulation on surfaces

- Condensation on windows

- Visible mold growth

- Discoloration around vents or walls

Neglected mold growth on a wall surface highlights the need for regular maintenance and cleaning.

The Moisture Test

High humidity can lead to mold growth and poor air quality. Use these simple methods:

- Purchase an inexpensive hygrometer (ideal readings should be between 30-50%)

- Place ice in a metal glass - if condensation forms on the outside within minutes, your air might be too humid

- Watch for persistent condensation on windows

The Candle Test for Air Leaks

Hold a lit candle near windows, doors, and electrical outlets. If the flame flickers, you've found an air leak that could be bringing in outdoor pollutants.

Carbon Dioxide Monitoring

While not a direct measure of air quality, CO2 levels can indicate how well-ventilated your space is.

Simple CO2 monitors are relatively affordable and can provide valuable insights about your ventilation needs.

Natural Indicators

House plants can serve as natural air quality monitors:

- Dying plants despite proper care might indicate poor air quality

- Unusual leaf discoloration could suggest specific pollutants
