Importance of Coverage Area & CADR when Buying an Air Purifier

Air purifiers are a relatively new technology and that is the reason why most people are not aware of the technical specifications that make a good Air Purifier. Unfortunately, some online or offline sellers take advantage of unsuspecting customers and this in turn results in a bad name for the whole product category.

In this post, we will cover all the features you should check before purchasing a home air purifier. We will also tell you about the two most important features which are Clean Air Delivery Rate and coverage area.

Features you should know before buying an Air Purifier for Home

Number of Filters

Ideally, a high-quality air purifier will have 3 air filters – a pre-filter, a HEPA filter and an activated carbon filter. The pre-filter acts as a buffer for the two main air filters. It removes large dust and debris from the incoming air so that the air that goes on to the main filters is cleaner. The pre-filter helps in extending the life of the main filters and is washable and reusable.

The High-Efficiency Particulate Air filter is the main component of a home air purifier. It removes up to 99.9% of the particulate matter (also known as PM) from the ambient air.

Finally, the activated carbon filter removes gaseous elements and volatile organic compounds such as formaldehyde fumes from the ambient air. It also removes odours by capturing the odour inducing particles.

Quality of Filters

Even an air purifier that has all three filters may not perform up to the mark if the manufacturer is not using the highest quality air filters. To make sure that you get maximum protection always buy air purifiers from trusted brands like Honeywell. They use international grade HEPA filters and have patented filter technology such as HiSiv.

Clean Air Delivery Rate

The CADR is measured in cubic meters per hour. Basically, it is the speed at which the air inside an ambient space like a bedroom or living room gets cleaned. An air purifier with CADR greater than 250 cubic meters per hour is recommended for home use. So, make sure that the product you are considering meets this minimum specification.

Coverage Area

The coverage area is the total area which an air purifier can effectively clean with the certified CADR. In ideal conditions, a Honeywell air purifier with the specified clean air delivery rate of 250 cu.m/hr can clean an area of 323 square feet within 15 minutes. If the area is more, the efficiency and effectiveness of the unit will go down. Then you will need an air purifier with higher CADR. So, before making the purchase make sure that you get the area specifications right for your living space.
