Conditions for healthier air
Mold, mildew, and other contaminants can put your health at risk. Maintain a healthy range of temperature and humidity in your home by finding the right equipment for your home.
Room air purifiers are portable, electric appliances that remove fine particles, such as dust and pollen, from indoor air. ENERGY STAR® Air Purifiers are 25% more energy efficient than standard models.
Regularly changing your HVAC equipment air filter can control dust and dirt buildup in your system. A dirty filter will reduce air flow and make the system work harder, which uses more energy. ENERGY STAR recommends checking your filter monthly during heavy use months (summer and winter) and changing the filter at least every 3 months.
You should also consider the MERV (Minimum Efficiency Reporting Values) rating of your air filter. Filters with higher MERV ratings are better at trapping specific types of particles, but filters with the highest MERV ratings will reduce airflow. ENERGY STAR recommends an air filter with at least a MERV 6 rating, but if you have pets or other air quality concerns you may want to consider a filter with a higher rating. If you opt for a higher MERV rating, consult your equipment manual or an HVAC professional to ensure that your system can accommodate the filter.
According to ENERGY STAR, the optimum relative humidity level for a building is between 30% and 50%. Anything above this range may promote bacteria growth.
Consider using a dehumidifier if your home has high humidity. Refer to the chart below to determine the recommended dehumidifier capacity.
|Condition without Dehumidification||Recommended Capacity Range, pints per day|
|Small-medium space (<2,000 sq. ft.)||Large space (>2,000 sq. ft.)|
|Slightly to Moderately Damp: space feels damp and has musty odor that may be intermittent. 50-75% relative humidity.||20-30||30+|
|Very Damp: space consistently feels and smells damp. Damp spots appear on walls and floors. 75-90% relative humidity.||25-40||40+|
|Wet: Walls or floor sweat, or seepage is present. High-load conditions such as laundry drying may be present. 90-100% relative humidity.||30-50||50+|
Properly functioning HVAC equipment can keep your home at an optimal temperature and reduce monthly energy costs. If your current equipment is unable to keep your whole home a comfortable temperature or if it’s more than 10 years old, you may want to consider replacing it with a more efficient ENERGY STAR unit.
Smart thermostats can automate temperature control to minimize energy use while you’re away from home and as seasonal outdoor temperatures vary. When your home is unoccupied, ENERGY STAR recommends setting thermostats 7 degrees higher in summer and a 8 degrees lower in winter.
Appropriate air sealing can also help control temperature and manage humidity.
