[This review was collected as part of a promotion.] I am loving this air purifier so far! The summers in our area are incredibly dry and dusty, plus we have two large senior dogs who stay inside with us most of the day, so a good air purifier is essential for our home! This one checks all the boxes! It's large, but sleek. More importantly, it is so quiet! We're currently using it in our primary bedroom and can hardly tell that it's on when it's on the lowest setting, but even the highest setting just sounds like a fan. The green light on top can be dimmed or completely turned off. And the best part-it takes hardly any time to notice a difference in air quality! Even in our larger rooms, 30 minutes to an hour on just the lowest setting makes a huge difference in the freshness of our home. Very happy with this product so far!
