Air pollution is a pervasive health concern affecting modern life, arising from outdoor sources like traffic fumes, wildfire smoke, and dust storms, as well as indoor sources like gas stoves and fireplace smoke.

To help protect yourself and your loved ones from poor indoor air quality, it’s a good idea to invest in a high-performance air purifier. However, it’s crucial to avoid investing in an air purifier that does not address your specific air quality concerns or, worse, is ineffective or even potentially harmful.

What are the key things to avoid when purchasing an air purifier? There are several critical factors to consider, from filter quality down to whether an air purifier will do more harm than good. Avoiding these seven common mistakes is a crucial first step in selecting the right air cleaning technology for your indoor environment.

CADR-focused ratings can be misleading. 

Understanding CADR’s Limitations:

While CADR provides some insights, it has significant limitations. CADR measures only the speed at which an air purifier cleans the air, not its long-term performance or ability to remove ultrafine particles, which are the most dangerous. A high CADR score may indicate quick air cleaning, but it doesn't mean the purifier is effective over time or can protect you from harmful ultrafine particles text.

Consider CCM:

Consider the Cumulate Clean Mass (CCM), which assesses the air purifier's long-term efficiency in filtering particulate matter and gases like formaldehyde. CCM provides a clearer picture of sustained performance over extended periods.
