What is a CADR: Everything You Need to Know
Ever since the pandemic began, everyone has become extremely careful about the air they breathe and it's quality. This is a good thing because a drastic fall has been reported in the transmission of air-borne diseases. Everyone has been using masks and investing in products such as air purifiers. A good Air purifier does more than just expel dust particles from your home. A lungful of air using a good air purifier does wonders to your mood as well.
So how does one know if an air purifier is good or bad? What should we look at when we purchase an Air purifier? What is the CADR rating that is mentioned on a few purifiers? Look no further, we are here with all the information you need!
What is CADR?
Clean Air Delivery Rate (CADR) is an acronym for Clean Air Delivery Rate. A CADR rating is a validated indicator of an air purifier's effectiveness. CADR ratings are based on CFM (cubic feet per minute) or m3/h (cubic meter per hour) measurements of air volume, with distinct scores for cigarette smoke, pollen, and dust. Three common pollutants are measured by CADR ratings: dust, pollen, and smoking. The AHAM (Association of Home Appliances Manufacturers) testing procedure yields an overall CADR rating as well as CADR values for dust, pollen, and smoke separately. By comparing these CADR values, you can determine how effective an air purifier will be for your particular air-cleaning requirements. The highest CADR value for smoke and pollen is 450, while the maximum rating for dust is 400.
What is the goal of a CADR air purifier rating?
The goal of a CADR air purifier rating is to provide you with an objective criteria for evaluating an air purifier's efficacy. As a result, when it comes to the speed and effectiveness of an air purifier unit, the Clean Air Delivery Rate is the most significant factor to consider when comparing air purifiers. It also aids us in determining the size (or, better yet, volume) of an air purifier we require for a certain room/apartment/house.
To help you understand, let us consider this simple example. An air purifier has a maximum airflow of 300 CFM. It has a CADR of 200 CFM. That implies a purifier could handle 300 cubic feet of air every minute. However, according to the CADR rating, it will only clean 200 CFM efficiently. The first air purifier cycle will not clean that 100 CFM.
What is a good CADR Score?
A good CADR rating is equal to at least two-thirds of the room’s area. A room of 10 feet by 15 feet, for example, has a surface area of 150 square feet. As a result, a smoke CADR of at least 100 would be considered a good CADR rating for an air purifier.
A higher CADR rating is preferable since higher test results show that the system is more effective at cleaning indoor air. A unit with a higher CADR rating of 300 for dust will eliminate dust particles more quickly than one with a lower CADR rating of 200. In that room, using an air cleaner with a higher CADR will simply clean the air more frequently and faster.
If you’re trying to remove smoke, allergens, mold, or pet dander from your space, try the Acekool CADR HEPA air purifier. The Acekool air purifier AF2 has a CADR rating of 415 m³/h. This can be placed easily in a large room. It has a 3 layer, high precision filter element including a True HEPA filter. With an excellent CADR score and a true HEPA filter, the Acekool CADR HEPA air purifier might be the best purchase you make during the pandemic.
It's time to finally breathe a sigh of relief and take a fresh deep breath in our home. We hope this article was informative and educational enough for you to make a wise decision in the purchase of an air purifier.
