I have always worried about the air quality in my home since Covid-19. Now, that it is beginning to be Fall and Winter seasons there are more sicknesses like the Flu and respiratory illnesses that I worry about. Now, that I have The Shark 3 in-1 Air Purifier at home, I don't worry as much because I know that it is doing a great job to keep the air clean. It was so easy to set up, I just took it out of the box, took the tape off of it and put the filter in the machine and it was ready to be used. I love that it has its own remote. It also has air and heat, so you can use it year round. I would highly recommend this product to anyone that wants clean air.
