First of all, I’m using a DIY scrubber because (1) it’s mainly just for my girlfriends benefit, we live somewhere isolated and (2) I can’t really justify purchasing a scrubber. I have a Vivosun fan, not sure of the model but can check if needed. It’s definitely not super expensive or top of the line but it has a greater CFM rate than required for my area. My question is, when I attach the scrubber, you can audibly hear the fan working harder and it feels like the current gets (somewhat) reversed. You can definitely feel air flowing through the activated carbon but the flow is certainly decreased. Will post pics of scrubber too if needed, just wondering if it’s even something I should worry about or if it will still be effective in removing odor.
