Swamp Coolers-Air Quality & Your Health

Both a comfortable temperature and a low humidity level are essential for indoor air quality and good health. While the main focus of cooling a home or building is on efficiency and cost, indoor air quality is equally important. Low air quality does not necessarily mean that there is excessive smog and smoke. It can also refer to any other air quality that could make it more difficult for the air to function properly. Swamp coolers or evaporative air cooler can help to moderate indoor airflow. They could also be a great option if you require better home cooling.

How Evaporative Coolers Move The Air

Swamp coolers and refrigeration-style AC bring cool air to a room. However, the way that airflow is cooled varies between each systems. A typical AC draws in warm airflow from space, then runs it through a condenser that removes moisture and blows it out of the room. The heat is usually vented outside. The constant cycling eventually cools the entire room. Evaporative coolers draw warm airflow from outside and pass it through cooling pads. The cool airflow is then sent back into the room via the water-cooled and wetted pads. You can also vent heat outside. However, in certain systems, you can adjust the temperature by opening and closing windows. This allows warm air flow to still flow in from the outside.

Swamp Cooling Technology: How Does Indoor Air Quality Change?

Swamp coolers are dependent on outside airflow to cool the house. This means that there is a greater amount of fresh, circulating airflow. If a building is closed, indoor air quality can become very poor. Dust, allergens, and increased humidity can all lead to unhealthy levels. Poor quality can also be caused by excessive humidity and dry conditions. A swamp cooler can bring in fresh airflow from outside and allow it to enter the home, improving indoor quality.

However, it is important to note that swamp coolers might not be able to change much indoors if the weather outside has already been bad. If you suffer from severe allergies to pollen, you should close your windows during the pollen season. This could impact the effectiveness of swamp coolers that rely upon open windows.

Are There Any Risks Of Poor Air Quality Coming From A Swamp Cooler?

Even if the swamp cooler is working properly, it will not cause poor quality. They can, however, make the indoor air quality less pleasant. A swamp cooler can raise humidity levels which can lead to poor indoor air quality. The evaporative cooling system can also be used to remove pollutants from the home, such as smoke from nearby cigarette smokers, wildfire smoke, or barbecue smoke. Although whole-house swamp coolers are equipped with filters, they don’t often remove fine particles, which can let pollutants in. If you live in an area with smoke or other air pollution, make sure your swamp cooling system has a strong filtration system. Even though it won’t eliminate all particulates it will reduce some.

What Can Be Done To Maintain Good Air Quality From Evaporative Cooling?

When using a swamp cooler, it is important to keep the filters clean and get filters that remove as much dust, pollen, and other particles from the air as possible. An extraction system should be installed on the unit. This will allow heat and moisture to escape without you needing to open windows. You can reduce the amount of poor airflow into your home by closing all windows. This is due to high pollen counts, wildfires, smoke, dust, or other outdoor problems.
