For the last 3 months, I have coughed incessantly at nights. I tried medication, dusting, cleaning my carpets and curtains but nothing worked. I read about using a Hepa filter to remove allergens from the air and decided to try one. I have had the Sciaire Mini Hepa filter for almost 2 months and I am so glad I got it. At a first glance, the hepa filter looks futuristic. I love the crisp white color and the sleek design. The touch pad is intuitive and only illuminates the buttons when in use. The set up process was very simple. The user manual was straightforward and easy to understand. The first night I plugged it in, it turned bright red, showing that my room had poor air quality. It took about 3 days to remove the allergens from the air. After a month of daily use,  I am no longer coughing at nights. My room also smells better too. I am very impressed with this hepa filter and would definitely recommend it.
