FiltreteOdor Defense Carbon Prefilter Room Air Purifier Filter 2-Pack

I tried to use it around the puffier filter but couldn’t insert the filter back in the device, it jammed due to the thickness that eliminated the space.

use this all the time

Out of all the carbon filter I tried, this is the best cut to fit carbon filter to get rid of Tobacco smoke smell. I now put it on my ceiling vent to prevent my neighbor's 2nd hand tobacco smoke from entering my unit. They are super heavy smoker and my apartment used to be filled with smoke thanks to the ceiling vent in my bathroom. I replace the carbon filter frequently so that the smoke doesn't a chance to make it to my unit. I tried other carbon filter before that are made in USA too but they don't work as well as this one. Sadly I was unable to add a MERV filter to this carbon filter to filter out the particulates from Tobacco smoke since otherwise it would be too heavy to stay on the ceiling vent, but this filtrate filter really works well at removing tobacco smoke smells on its own.Personally I found this carbon filter does a better job at absorbing tobacco smoke than the dyson purifier (which has HEPA + Carbon filter) that I have in my unit (I have a few different models / brands purifiers). I would recommend this carbon filter which is easy to to cut for anyone who needs to remove tobacco smoke smell.

When neighbor smoke at home or cooks, the smoke could come in through vent. After use this (pair with 3M filter), I could barely smell any smoke, although I use air purifier too at room

My wife has severe allergies. We have a merv13 filter, but some odors still get through. This carbon filter, although it was missing the gizmos to attach, eliminated, for now, the odor.

These are expensive filters that require hooks to attach them. The box says hooks are included, but they aren’t. Waste of money without the hooks
