How to get rid of a septic tank smell?
assistant
The first step is to make sure the area around the septic tank is free from food scraps and other debris. This can help reduce odors in the air. 2 You can also try adding activated carbon or charcoal filters to your home's HVAC system, as these will absorb any bad smells. 3 If that doesn't work, you may need to hire a professional to inspect the septic tank and clean it out. 4 Finally, you can use an odor eliminator like baking soda or vinegar to neutralize any remaining smells.
