Home Air Purifier Efficiency Calculator
The ultimate tool for understanding your air purifier.
This calculator is designed to help you decide on the best air purifier for your home, ensuring you breathe cleaner, healthier air every day.
Provide three key pieces of information:
Room Size: Enter the room size in square feet. If the room is rectangular, multiply its length by its width. Split non-rectangular rooms into rectangular sections, calculate each section’s area, and add them together.
Air Quality Index: Input the current air quality index (AQI). Check the AQI in your area via environmental agency websites, like AirNow for the United States.
Purifier CADR Rating: Insert your purifier’s Clean Air Delivery Rate (CADR) rating, which measures its filtering capacity. You can find it in the product’s specifications or description.
Once you’ve entered all the necessary information, our calculator will provide an estimate of how efficiently your air purifier can improve the air quality in your room. Remember, this is just an estimate, and actual results may vary based on factors like the specific pollutants in your home and how often you run your air purifier.
