Highlights
Quality
I was a bit surprised at the quality.
Only complaint i have is they are not cut to size yes they have a template to cut them but i would prefer cut product.
It didn't match the quality of the original filter that came with my air purifyer.
The premium ones are thicker and seemingly better quality, offering an 'odor-reducing' quality.
Competitiveness
