Benefits Beyond Air Quality
Humidity Control: Salt helps manage moisture, reducing mold and dust mites.
Mood Boost: Some find the sharp scent of vinegar energizing and mentally refreshing.
Eco-Friendly: This method avoids synthetic chemicals and disposable air fresheners.
Versatility: The same mix can be used for cleaning or even as a DIY pest deterrent (it helps block ant trails and repel some bugs).

Limitations to Keep in Mind
Strong Smell: Vinegar’s scent may be too sharp for some people, though it usually fades after a few hours.
Not a Full Replacement: It won’t capture fine dust or VOCs like a HEPA purifier can. It’s a basic, supplemental method—not a complete solution.
Room Size Matters: Effectiveness is best in smaller or enclosed spaces where the acetic acid can circulate more easily.
What Does Science Say?
While specific studies on salt and vinegar as air purifiers are limited, their individual properties are well-documented:
Acetic acid kills many bacteria and some viruses on surfaces.
Salt reduces airborne moisture and can help with allergens.
More research is needed to fully confirm their air-purifying power, but anecdotal evidence and centuries of use support their value.
Real-World Testimonials

FAQ
Will the vinegar smell linger?
It usually fades quickly as it evaporates, leaving a clean scent.
Can I use any type of vinegar?
White vinegar is best—cheap, colorless, and high in acetic acid. Other types (apple cider, balsamic) may work but can stain or smell stronger.
How often should I replace it?
Every 2–3 days for best results.
In Summary
