How to control humidity in your home with a whole house humidifier and indoor air quality system.

How to lower humidity in your house

Indoor air quality is an essential factor in the overall health and well-being of you and your family. Humidity levels in your home contribute to air quality and high humidity levels may promote mold and bacteria growth, which can worsen allergies, asthma and other respiratory issues. High moisture levels can also lead to increased energy costs and home damage.

Whole house humidifiers along with indoor air quality systems are effective solutions for too little humidity. These systems work with the ductwork in your HVAC system, optimizing its functionality as your home's respiratory system. When it breathes more efficiently, you and your family will, too.

At Petro, we're committed to helping homeowners improve their air quality by offering humidifiers and indoor air quality systems that are easily installed into your existing HVAC system.

Ideal indoor humidity levels

According to the Environmental Protection Agency (EPA), indoor relative humidity should not exceed 60%, with ideal levels between 30% and 50%.

When your relative humidity is higher than 50%-60%, several moisture problems can result, including:

  • Mold and bacteria growth
  • Mildew smell
  • Interior condensation on windows
  • Air that is moist and clammy
  • Rotting wood
  • Intensification of allergies

When your relative humidity is lower than 30%, the excessive dryness can cause the following conditions:

    Infestations of dust mites and other pests

    Aggravated asthma and allergies

    Dry mucus membranes, leading to difficulty fighting off colds and other infections

Why indoor humidity levels are important

Why controlling humidity in your house is important

Keeping humidity levels in your home within the recommended range is essential for your comfort, health and your wallet.

1. Temperature
Apart from health issues, unbalanced humidity levels in your home can lead to increased energy bills. For instance, excessive humidity can make the temperature in your home feel much warmer, which can cause you to overuse your AC/HVAC system, add to energy bills, and decrease your home's energy efficiency.

2. Mold and mildew
If the humidity levels in your home are excessive for prolonged periods, mold and mildew may build up in your air ducts and other areas. Mold exposure can trigger or worsen asthma symptoms and allergic reactions.

3. Respiratory health
Research shows that Americans spend approximately 90% of their time indoors and about 70% of that time at home. People who are the most vulnerable to the harmful effects of indoor air pollution — those with cardiovascular or respiratory disease — may spend even more time indoors. Indoor concentrations of some pollutants have increased in recent decades due to energy-efficient building construction and increased use of synthetic materials in furnishings, personal care products, household cleaners and pesticides. These can also lead to inadequate air circulation and combined with excessive humidity in your home, can cause or exacerbate respiratory health issues.

How to regulate indoor humidity

Tips on controlling humidity
