How Much Air Ventilation Does Your Home Need?

Like your lungs, proper ventilation is important in our house to keep air fresh and healthy to breath. How can we achieve this?

Ensure the IAQ (Indoor Air Quality) is high to keep your home free of allergens and other particles that can get into the air. Lack of ventilation can lead to unhealthy levels of mildew, radon, carbon monoxide, dust, and gases. Looking at your airflow and ventilation condition is one of the simplest ways to keep your home safe and good IAQ. Bringing in the outside air can assist in getting rid of stale air, excess moisture, airborne contaminants, and dust inside the house. How much airflow does your house require, then? Read below for that and other questions answered by our HVAC gurus.

How is Home Ventilation Measured?

Depending on your home size, fresh air from the outside will be needed to keep the air inside healthy. The air exchange rate is the time it takes for external air to replace the air inside a building completely. Air changes each hour should be at least 35% of a home's total air volume, as the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) recommends. In addition, each individual should have access to at least 15 cubic feet of air every minute. For example, a three-person home should have at least 45 cubic feet of air exchange per minute. For this reason, proper ventilation is essential for maintaining high IAQ.

How Does a Home Ventilate?

You must let your home breathe to ensure it's well-ventilated and get the air exchange rate you want. When ventilation is low, dust, gases, and other pollutants can build up, as well as too much moisture and humidity. You should let in as much outside air as possible to flush out pollutants and improve the air quality. Some airflow happens naturally since homes aren't airtight. A ventilation strategy is necessary, however, to guarantee adequate airflow.

Ways to Get More Fresh Air

You can increase ventilation in your home in several ways, including installing more windows and making better use of your heating, ventilation, and air conditioning system.

Open Windows and Doors: Natural ventilation, achieved simply by opening windows and doors, is a great way to exchange stale air outside for fresh air within. Increasing the pace at which air is exchanged by opening windows and doors is a simple and easy way to reduce indoor air pollution. Be aware of the external air quality, but keep in mind that contaminants from the outside might also enter your home. Yet, this choice may only be appropriate for some.

Spot Ventilation: Spot ventilation uses directional exhaust fans placed strategically around a building to remove airborne contaminants as they are formed. Among common exhaust fans are those installed in kitchens and bathrooms to remove steam and humidity.

Whole-Home Ventilation: Whole-House Ventilation Systems Heating, ventilation, and air conditioning (HVAC) systems are excellent illustrations of whole-ventilation systems in the home. Heating and cooling systems efficiently regulate airflow through fans and duct networks. They will draw in fresh air from the outside and release stale air to the outside of your home. For this, they are among the safest and most effective ventilation choices available. Whole-house ventilation systems that save energy while increasing airflow are another option.

Signs You Need Better Ventilation

Do you need more ventilation and clean air in your house? You should keep many red flags in mind:

• Mold and mildew spores, condensation, and other telltale symptoms of high humidity
• Especially lingering instructions from the kitchen, bathroom, and attic
• Radon and carbon monoxide levels are significantly higher than average
• Particles of dirt piling up

Contact an HVAC service to have an expert take accurate readings of your indoor air quality and ventilation exchange rate. If you're having trouble with air circulation, a technician can evaluate the condition and make recommendations.
