**Scientific Explanation of Vinegar and Salt Reaction**

The combination of vinegar (acetic acid) and salt in water creates an acidic solution that releases ions. This reaction neutralizes odors by breaking down airborne particles. Vinegar’s antibacterial properties also help reduce mold and bacteria, leading to cleaner air.

**Immediate Effects on Air Quality**

When the vinegar-salt mixture is placed in a room, air quality improves within hours as odors like cooking smells, pet odors, and mustiness dissipate. The result is a fresher, more pleasant environment.

**Long-Term Benefits**

Using this mixture regularly helps maintain fresher air and reduce recurring odors. Some users report fewer allergy symptoms and improved respiratory comfort due to cleaner air.

**Health and Safety**

While safe for household use, the mixture should be kept away from pets and children to prevent accidental ingestion. People with vinegar allergies should exercise caution, though such allergies are rare.

**Limitations**

This solution is not a substitute for deep cleaning or proper ventilation. It cannot eliminate strong, permanent odors or severe mold issues, and some may find the vinegar smell unpleasant initially.
