Whether you have lived in one yourself or are helping your student move-in, you will know that dorm rooms can raise significant concerns about health and cleanliness.¶ÀÁ¢ºÚÈËÔÚÏß¹Û¿´ÍêÕû°æ cleanliness. Mold spores are a significant concern in dorm rooms and are a top reason why an air purifier should be on your shopping list. Whether due to poor ventilation, humidity, or clutter, mold can thrive in dorm rooms under the right conditions which is a problem because exposure can lead to various health issues, including allergies, respiratory problems, and asthma. An air purifier will not only help your student breathe healthier, cleaner air but also help improve their quality of sleep and eliminate other allergens, dust, and mold in particular.

Test Scenarios and Performance

To test the performance of the air purifier, we turned on the air purifier on the lowest setting and closed the door, allowing the air purifier to clean the air for 30 minutes. After 30 minutes, we measured and recorded the air quality at each mark. We repeated this process for the high setting and also added pet hair to a designated mark to determine how well each air purifier filtered pet hair. After testing, measuring, and recording, we removed the filter and visually inspected how much pet hair had been captured. The Levoit Vital 100S cleared our small 728 cubic feet test room of all PM1 particles in 37 minutes ¡ª this is 11 minutes faster than the non-smart Vital 100 (48 minutes) and 17 minutes faster than the Levoit Core 300 (54 minutes).
