Air purifiers improve air quality by scrubbing and regulating humidity levels. Pressure washers circulate air over chilled water to remove impurities and add moisture. Air washers use a similar concept with added filters. Efficient devices can reduce energy consumption, and building design can also help.
An air purifier is equipment designed to improve air quality by scrubbing the air moving through it and regulating humidity levels to keep the environment consistent. Air purifiers are used as part of air conditioning and air quality systems. A number of companies produce equipment designed for different applications, including machines rated for buildings of various sizes. It is important to select the right equipment, as an undersized device will not be able to keep up with the airflow, and equipment not designed for high particulate level applications may fail due to overload.
The pressure washer works by continuously moving a supply of air over chilled water and pushing the air out to circulate it through a room or building. Moisture is drawn from the air as it reaches the dew point by passing over cold water. In addition, impurities in the air such as pollen and dust precipitate. The air coming out of the machine is drier and fresher. It also contains fewer particulate matter, making breathing safer and more comfortable.
In climates where the air is extremely dry, a pressure washer can work to raise the humidity. Dry air can be difficult for people to breathe. It can also contribute to the development of dry skin and can damage items stored in the environment. The pressure washer removes particles from the air and adds a moisture injection to keep the climate at a constant humidity level for greater comfort. Environments such as museums and archives need precise climate control to protect their collections and an air purifier can help with this.
Simply using a fan to draw air over a container of fresh water can clean the air and make your environment more pleasant. Air washers draw on this basic concept. The design can include extra features such as filters to trap harmful particles in order to increase the purity of the air.
Like other devices that clean the air, an air purifier can consume a lot of energy. Some are designed to be more efficient and may have features designed to reduce energy consumption. Constructing buildings with efficiency in mind can include reducing the load on air washer systems by providing pre-filtration and designing the building to maintain a constant temperature and humidity level on its own. It is also possible to set these devices on timers and adjust their performance specifications to reduce energy consumption.
