Work as advertised and the customization option is useful

My review is not completely negative, but this product did not work for me. For context, I live in a small apartment with a small central air unit. I kept getting gunk that was coming out of the air vents, so I ordered these. They were very easy to cut and install, and they can be cut to whatever size is needed. They worked very well for their intended purpose of removing dust and bad smells. I did end up removing them, only because even though they were pretty thin, they reduced the airflow in the apartment by a ton and caused heating and cooling issues. If that’s not an issue for you, I highly recommend this product.

Seems to do the intended job. I wrap the filter in my air purifier. I vacuum it off weekly and it seems to work for about a 6 month. I've read that you can wash and reuse this type filter, but they really don't work once washed, because all the charcoal washes out.

Carbon fibre pre-filters do a great job of minimising odours and catching material allowing your expensive HEPA filter to last longer by filtering out ultra small particulate matter. Without a pre-filter it clogged up very fast so this saves you money in the long run and it’s easily washable.
