I've been trying your air purifier in the car for two weeks now. I had one like this 14 years ago and you could hear it making noises and yours not. Which has its positive sides. My previous one also had an obvious airflow that really smelled like clean air. It's not like this. Yours isn't as obvious to make a difference, although one of my masks fell on the top rim one day and I smell the clean air that I remember. I have had an air purifier in my home for many years and I love the fresh air smell it gives off. I bought 9 units of these for our community to use in vehicles/tractor cabs with our care law money because I thought it would be great during this COVID pandemic. I hope the boys like them.
