The Blueair Classic Pro CP7i does a great job of removing various pollutants, but its benefits extend far beyond that. For starters, it is one of the quietest air purifiers in its size range. This appliance is powerful enough to cover rooms measuring up to 1,400 square feet (130 square meters), but when we measured its noise levels at the highest fan speed, we noted just 52 dB — which is no louder than the sounds made by a refrigerator. You can easily place it in a bedroom or a study without worrying about excessive noise levels.
Moreover, the Blueair Classic Pro CP7i comes with an excellent set of features and the coveted Asthma and Allergy Friendly certification. This air purifier is among the handful of models that can provide you with real-time and historical air quality measurements, and it has been independently tested to verify its allergen-busting capabilities. Now, you can get the Blueair Classic Pro CP7i for just $489.99.
