Alen air purifiers have a CFM rating of up to 350, which is on the higher end for a home air purifier.Īnother important factor to consider when exploring an air purification system is air changes per hour (ACH). The CFM rating of an air purifier will determine its efficacy at removing airborne particles, ranging from dust and pollen to smoke and pet dander. Understanding the ACH rating of an air purifier can help individuals choose the right product for their specific needs and improve their overall indoor air quality.
The higher the ACH rating, the more times the air in a room is cleaned per hour, which can lead to improved air quality and health benefits for individuals who suffer from allergies, asthma, or other respiratory issues. Air purifiers are designed to help improve indoor air quality by removing pollutants and contaminants from the air, and the ACH rating is an important factor in determining the effectiveness of an air purifier. Air Changes per Hour (ACH)Īir changes per hour (ACH) is an important concept in the realm of air purification, as it refers to the number of times that the entire volume of air within a room is exchanged with fresh air per hour. Horsepower is an important factor to consider when choosing a car, especially if you are interested in performance.ĬFM and horsepower are both measures of performance, applied to different aspects of the devices they describe, that provide a way to measure the product’s power and output. The higher the horsepower, the more power the engine can produce, and the faster the car can accelerate and reach higher speeds. In the context of a car, horsepower refers to the engine’s ability to produce power to move the vehicle. Specifically, one horsepower is equal to the amount of work required to lift a weight of 550 pounds by one foot in one second. It represents the amount of work the engine can do over a given period of time. Horsepower is a measure of the power output of a car’s engine. Similarly, horsepower measures the power output of a car’s engine. A higher CFM rating generally means that the purifier can clean the air in a larger room or space more quickly and efficiently. It tells you how quickly the purifier can circulate air through a room, and therefore how effectively it can remove airborne particles like dust, pollen, and pet dander. They are both measures of performance, simply applied to different aspects of the devices.ĬFM measures the volume of air that an air purifier can move in one minute. “Cubic Feet per Minute” (CFM) in air purifiers can be thought of as horsepower in cars.
It’s important to choose an air purifier with a CFM rating appropriate for the size of the room where it will be used.
The higher the CFM, the more air the purifier can circulate and clean in a given amount of time. In other words, it’s a measurement of the purifier’s airflow capacity.įor air purifiers, CFM is an important specification as it indicates the purifier’s ability to clean the air in a room. CFM stands for “Cubic Feet per Minute,” and it’s a measure of the amount of air that an air purifier can move through its filter in one minute.
