Frequently Asked Questions

Common questions about indoor air quality and ventilation

What is ideal indoor humidity?

Indoor relative humidity should typically be maintained between 30-50%. This range prevents mold growth, reduces dust mites, and maintains comfort without causing condensation issues.

How often should air be exchanged?

Residential spaces generally require 0.35-0.5 air changes per hour minimum. Higher rates may be necessary in kitchens, bathrooms, or spaces with specific air quality concerns.

When should I use mechanical ventilation?

Mechanical ventilation is recommended when natural ventilation cannot provide adequate air exchange, in tightly sealed buildings, or when outdoor air quality is poor.

How can I detect mold early?

Regular visual inspections of moisture-prone areas, monitoring for musty odors, checking for water stains or discoloration, and maintaining proper humidity levels help with early detection.

What are common indoor air pollutants?

Common pollutants include VOCs from materials and products, particulate matter, carbon dioxide, humidity-related issues, and biological contaminants like mold spores and allergens.

How does ventilation affect energy use?

Ventilation impacts heating and cooling loads. Heat recovery ventilation systems can recover 70-90% of thermal energy, significantly reducing the energy penalty of fresh air introduction.
