Review on Cabiclean 2 HEPA Filters with 6 Carbon Pre Filters for AP-1512HH Coway Air Purifier by David Cash

As you can see the image on the left is brighter and much less reliable than the filter on the right. Left is a Cabiclean pre-filter and right is a different brand. We will be buying other brands of pre-filters in the future as they are not good enough compared to the competition. If you want to extend the life of your HEPA filters and air purifiers, you need a pre-filter that removes as many macromolecules as possible. And as you can see from the translucent holes, this brand doesn't quite do the job.
