The best way to remove fart smell from a room is to open windows and doors to ventilate the room.
Opening the windows will allow fresh air into the room and help the fart smell dissipate and leave the room through the window.
Opening doors can also help the fart smell escape the room and go into other rooms or if the door leads to the outside then the fart smell will leave through the door and go outside.
If you have any lingering fart smell odors in the room you can use some baking soda or an activated carbon filter to absorb and neutralize the odor.
I always try to open the windows when I have farted in my room and it's the quickest and best way of getting rid of the fart smell.
Even in winter I open the window to the room I'm in if I farted or have a bad odor inside the house or room and leave it open for a few minutes to allow some fresh air in.
This gets rid of the smell quickly.
Using some air freshener spray can also mask the odor in the room after farting, but opening windows fully gets rid of the fart smell.
To hide the smell of your farts, use activated charcoal pads or underwear, consume probiotics and a fiber-rich diet, and employ masking techniques like using air freshener or lighting a match.
For immediate, discreet solutions when farting, activated charcoal pads that can adhere to your underwear can trap odor molecules, while diet adjustments can reduce the production of smelly gas over the long term.
