Here are three key considerations when calculating the air exchange rate for your air purifier:

  1. Airflow rate: Measure the volume of air that your air purifier can process per minute. This information is usually provided by the manufacturer and is measured in cubic feet per minute (CFM).

  2. Room size: Calculate the volume of your room by multiplying its length, width, and height. This will give you the total cubic feet of the space.

  3. Ventilation requirements: Determine the number of air exchanges per hour required for your specific needs. For example, a bedroom may need around 4-6 air exchanges per hour, while a kitchen or bathroom may require 8-10.

Identifying Pollutant Types and Levels

When it comes to indoor air quality, understanding the types of pollutants present and their levels is crucial.

Different pollutants, such as particulate matter, volatile organic compounds, and gases, can have varying health impacts.

Measuring pollutant levels accurately enables us to choose an appropriate air purifier that can effectively remove these pollutants and improve the overall air quality in our indoor spaces.

Types of Pollutants

Different types of pollutants, such as dust, pollen, and pet dander, can affect the air quality in your home. To combat these pollutants, it is important to choose the right air filter for your needs.
