I use this in the winter to purify and deodorize the house in the winter. The air can feel pretty stale after being stuck inside all winter. I just connect this directly to my blower and run it in whatever room needs it. Truly feel like it cut down on our sickness and made the air feel light and fresh! Throw a dryer sheet on the output side and it smells like spring all winter.

I bought this to use with a dry herb vaporizer indoors to eliminate the smell. I’m using it in a 10x12 room with the fan pulling across the surface area of the filter, with the fan blowing up towards the ceiling. I set the fan to about 60% and sit next to the filter with my noise canceling headphones (the volume isn’t awful but it can be annoying). I blow the vapor into the filter directly. Where this really works great is when you need to grind flower. Even CBD flower at 3%+ terpene content will completely destroy the room and outside hall unless I use this at the desk next to my grinder. I have to keep my room HEPA air filter running or when I switch it on after a big session or several sessions the room gets foggy and the HEPA filter works overtime. Obviously this carbon filter isn’t designed to filter contaminants, only smells, so it’s working as designed. Just something to keep in mind. I do not smoke so I have no idea how well it may work with combusted smoke vs. vapor. I think I can probably make this way more efficient using a half-open box so it draws the air in better from the side facing me, which may allow me to be able to reduce the fan speed and improve efficiency. I am playing with using activated carbon foam rolls made for AC window units and furnace filters as a pre-filter to increase the lifespan. They’re thin enough that they don’t seem to increase air resistance and super easy to cut to length and replace.

I was extremely surprised how strong the fan was being that it was built in and a lot smaller than the other 4-in fan that I purchased. With that being said it is about twice as strong as the other setup that I have and if I would have known that to begin with then I would have just purchased these from the beginning. With that being said I highly recommend them and they are very efficient and simple to use. And it also you can use it for intake or exhaust. Just flip it around and that will either breathe in or breathe out the airflow. It's a little bit louder than my other device but that's okay because the event fan is traveling a distance and also with curvature so I believe that's what's making a whistling noise. The carbon filter reduces the smell so it works very good! The only issue is I only have one of them , not four! LOL

We bought a whole new set up on Prime Day in July and purchased this as an extra filter to have on hand when that one was ready to be replaced. Put this one on a couple days before Christmas because the other one had reduced air flow after 6 months of use. Big mistake. This thing absolutely does not scrub the air at all. We had odor in the room it was used in and mildly even in the hallway and stairwell. We couldn't get it to go away. Never had an issue before. It's the new filter. Useless garbage. And past the return window because I bought it on sale on Prime day. Never again will I try an on sale off brand. It didn't save me any money at all.
