COVID-19 and Indoor Air Quality

The COVID-19 pandemic has brought the importance of indoor air quality to the forefront of our minds. As we spend more time indoors to stay safe, it’s essential to ensure that the air we breathe is as clean and healthy as possible. Here are some things you should know about COVID-19 and indoor air quality.

How Does COVID-19 Spread?

COVID-19 is primarily spread through respiratory droplets that are released when an infected person talks, coughs, or sneezes. These droplets can be inhaled by others, or they can land on surfaces and objects where they can be picked up by people who touch them and then touch their mouth, nose, or eyes.

What is Indoor Air Quality?

Indoor air quality refers to the quality of the air inside buildings and other enclosed spaces. Good indoor air quality means that the air is clean, healthy, and free of pollutants that can harm human health.

How Does Indoor Air Quality Affect COVID-19 Transmission?

Poor indoor air quality can contribute to the spread of COVID-19 by allowing respiratory droplets to linger in the air for longer periods. Additionally, if there are particles or pollutants in the air, they can attach to respiratory droplets and potentially increase their infectiousness.

What Can You Do to Improve Indoor Air Quality?

To improve indoor air quality and reduce the risk of COVID-19 transmission, there are several steps you can take:

1. Increase ventilation: Ensure that your HVAC system is providing adequate ventilation by increasing the amount of outdoor air brought in and reducing recirculation of air.
2. Use high-efficiency air filters: Install high-efficiency air filters to capture particles and pollutants in the air.
3. Use air purifiers: Consider using portable air purifiers with HEPA filters to supplement your HVAC system’s filtration.
4. Maintain humidity levels: Keep indoor humidity levels between 30-50% to help reduce the survival rate of viruses and bacteria.

By taking these steps, you can help improve the indoor air quality in your home or business and reduce the risk of COVID-19 transmission. Contact a professional at Seattle Heating & Cooling for more information on improving indoor air quality. 206-848-8080.
