I'm attaching a picture of the filter for this air purifier which I've only had about 3 weeks. The filter is so dirty can't even see through it. I am impressed with how well the Puroair air purifier cleans the air! I have 3 of them!
I am understanding that I have to have the app to make the air cleaner work and I don't want to have another app on my phone. My phone is already very slow and it's old so adding another app to the memory really stinks. I hope I'm wrong and that I could use that without having to happen just use the air cleaner by itself if that's the case then my rating would be way higher.
