Clean Air Delivery Rate, also known as CADR, is a measure of how well an air purifier can clean the air in a room. Imagine the air around you is like a soup, and it has small bits of dirt, dust, and other pollutants mixed in it. The air purifier is like a really good strainer that can take out the unwanted bits from the soup. CADR is like a way to measure how much soup the strainer can remove from that air in a certain amount of time.
So, imagine you have an air purifier in your room that can clean the air really well. The CADR number tells you exactly how many cubic feet of air the purifier can clean in one minute. The higher the CADR number, the faster and more efficient the air purifier can clean the air.
For example, if an air purifier has a CADR of 200, it means that it can clean about 200 cubic feet of air in one minute. This number helps you to determine if the air purifier is good for the size of your room.
In simple words, CADR tells you how much air an air purifier can clean at any given time, and a high CADR means that the air purifier is efficient at cleaning the air in your room, making the air cleaner and healthier for you to breathe.
