For those looking for an effective air purifier, besides considering filter specifications, another extremely important feature is the CADR value. The full name is Clean Air Delivery Rate.
Why is CADR important in air purifiers?
First, you need to know that CADR is defined by the Association of Home Appliance Manufacturers (AHAM), used as an indicator of air purifier performance efficiency—how much clean air it can deliver, measured in cubic meters per hour. This means the higher the number, the higher the air purification volume efficiency. This CADR value can be used to compare the performance of different air purifier models.
However, the number isn’t everything you need to know about CADR in air purifiers.
Don’t be fooled by CADR values
Air purifiers will indicate their purification performance numbers based on the maximum value used only initially. But in reality, purification efficiency decreases throughout the product’s lifespan according to filter performance.
Therefore, when looking for a high-performance air purifier, you must look for filter innovation that can purify and deliver clean air at a consistent rate throughout the product’s lifespan, to ensure the air purifier can deliver clean air throughout its operational life.
