Review on Eureka NEA-F1 True HEPA Filter: 🔍 Replacement Filter for Eureka NEA120 in Black by Terry Wright

we bought it 1.5 months ago. it is easy to use but a bit heavy. The main problem is that we sneeze every time it turns on. We contacted the manufacturer, they just told us to clean the filter and the cleaner. Filter and machine are clean but we are still sneezing and they have no solution. We don't have any allergies. we want to know why the sneezing continues. Besides, the car is fine. Also how can we know that the machine is cleaning the air or killing viruses (there is no way to see how the UV light shines). There is no air monitor on the machine. the breathing air is the same before and after operating the machine for several hours.
