Method 5: Humidification

Imbalance humidity can lead to poor air quality

Humidity – or the amount of water vapor in the air – is pivotal in maintaining indoor air quality. It’s all about finding a balance: too high, and you risk fostering mold growth and dust mites; too low, you may be experiencing symptoms like dry skin, irritated nasal passages, or aggravated respiratory issues.

So what’s the ideal humidity level for a comfortable indoor environment? It’s generally between 30% and 50%.

Here are a few suggestions to maintain this balance:

  1. Humidifiers: These devices increase humidity levels by releasing water vapor into the air. They’re particularly useful in dry climates or during cold winter months when heaters can dry out the indoor air.
  2. Dehumidifiers: Useful in damp climates or areas in your home prone to moisture (like basements), dehumidifiers work by removing excess moisture from the air.
  3. Hygrometer: This handy tool measures your home’s humidity level, helping you determine when to use your humidifier or dehumidifier.
  4. Ventilation: Good ventilation, especially in high-moisture areas (like bathrooms and kitchens), can also help regulate humidity levels.

Method 6: HVAC System Filters

Your home heating, ventilation, and air conditioning (HVAC) system plays an indispensable role in maintaining home air quality. It’s essential to choose and maintain the right air filters to keep the HVAC system working efficiently and effectively.

Here are a few maintenance tips for your own HVAC systems and system filters:

  1. Choose wisely: Opt for filters with a high Minimum Efficiency Reporting Value (MERV) — between 8 and 13 — to capture the most particles without inhibiting airflow.
  2. Regular replacement: Depending on factors such as usage and the presence of pets, replace your filters every 1 to 3 months. During seasons with heavy HVAC usage, more frequent replacement may be necessary.
  3. Scheduled inspection: Inspect your filters for signs of wear, clogging, or damage. A visual check can often indicate whether a replacement is in order.
  4. Clean ducts and vents: Periodically clean your HVAC system’s air ducts and vents to remove accumulated dust and debris, ensuring optimal airflow.
  5. Get it serviced: Regular professional maintenance conducted at least once a year by an HVAC specialist can help identify and resolve concerns before they become significant issues.
