Preparing Your Southern California Home for High Ozone Days
Living in Southern California, you likely are used to hearing the term “high ozone days” during the warmer months of the year. When these air quality alerts happen, they can directly affect your health and the air quality in your home. It’s vital to understand what causes these events and how you can use your HVAC system to protect your health and your indoor air.
What Are High Ozone Days?
High ozone days occur when the ground-level ozone concentration levels rise to unhealthy levels. It’s important to note that, while the ozone layer high up in the atmosphere is quite protective for the planet, ground-level ozone can be harmful. This ground-level ozone forms when pollutants react to sunlight on hot days with little wind. Young children, older adults, and those with respiratory conditions, such as asthma, should limit outdoor activity on high ozone days.
Ozone Contributors
There are many different contributors to ozone pollution that are especially common in Southern California. Some of the biggest contributors are industrial pollution from factories and refineries, vehicle emissions, and VOCs from gasoline, paints, and other household products. These pollutants all react with sunlight to form harmful ozone.
Southern California’s valleys and surrounding mountains allow trapped, polluted air to remain instead of dispersing. Add in the frequent sunshine that this region experiences, and you have a recipe for poor air quality.
When Are High Ozone Alerts Issued?
High ozone alerts happen most commonly throughout the summer months between May and October. Ozone levels usually peak in the afternoon and early evening hours. This is because the pollutants have had time to react in the sunlight since morning. It’s important to always check air quality forecasts so that you can plan to stay safe during a time when ozone levels are high.
How Ozone Pollution Affects Indoor Air Quality
Many people think that just staying indoors will automatically protect them from the outdoor pollution on those high ozone days. While being indoors can help, it’s important to realize that outdoor ozone pollution can seep into your home. It can enter through open doors and windows, gaps in your exterior walls, and through poor insulation. If you don’t have proper precautions in place, your indoor air quality can still be significantly affected on high-ozone days.
HVAC Tips for Cleaner Indoor Air
Your HVAC system can play a vital role in reducing indoor exposure to ozone and other pollutants. Using it alongside other steps can help keep your indoor air quality safe and clean for your entire family. One of the best things you can do is keep your windows and doors closed on high-ozone days.
It can be highly beneficial to check for air leaks on the exterior walls of your home. These tend to develop around your door and window frames and can let outside air seep in. You can seal these with weather stripping, caulking, or even spray foam insulation. This simple step can greatly minimize your risk of outdoor air pollution entering your home.
Another thing to consider is your air filter in your HVAC system. Standard HVAC filters are specifically designed to capture larger particles like dust. However, they’re not effective when it comes to gases like ozone. Investing in an activated carbon filter is a great way to reduce odors and gaseous pollutants like ozone. Be sure to check your HVAC system guide to confirm it’s rated to handle the filter you’re considering. Not all older systems are compatible.
The best protection against ozone and other airborne pollutants is to invest in a whole-home air purification system. We typically install these inside your existing heating and cooling system. This adds an extra layer of protection to your entire living space. These systems can use a variety of different technologies to filter the air in your home. Different models include features such as multi-stage filtration, activated carbon, HEPA filters, and UV germicidal lighting.
