Lately, videos on the internet and WhatsApp forwards have been circulating, promoting a simple home hack: placing an earthen pot (matka) filled with water in an air-conditioned room to naturally humidify the air. This idea sounds comforting—just a clay pot quietly fixing dry skin problems without any fancy gadgets. But does it actually work, or is it just another life hack that sounds good but delivers little?
To answer this question thoroughly, we need to understand three key aspects: how earthen pots behave, how humidity works, and what an air conditioner does to indoor air. The truth lies somewhere between technically correct and practically ineffective. Yes, an earthen pot can release moisture into the air, but whether it meaningfully changes your room’s humidity is a different story.
The Basic Science Behind the Idea
Earthen pots are porous, with tiny holes that allow water to slowly seep out and evaporate. This process naturally cools the water inside and adds some moisture to the surrounding air. That is why a matka keeps water cool even in hot weather. However, cooling is not the same as humidifying an entire room, especially when the AC is running.
Does It Work at All?
Sort of, but do not expect miracles. Any exposed water surface—whether a bowl or a pot—will raise humidity slightly due to evaporation. However, the effect is minimal and depends on several factors: the size of the water surface, room temperature, air circulation, room size, and whether doors or windows are open. A single pot in a large room provides only a gentle lift in humidity, not a real fix.
What Happens in an Air-Conditioned Room?
This is where the hack falls apart. Air conditioners do not just cool the air; they also remove moisture as part of their operation. Even if the pot adds a little vapor, the AC pulls it right back out. It becomes a tug of war, and the AC always wins.
Why the Earthen Pot Fails in an AC Room
Several reasons explain why the pot does little in an air-conditioned space. First, evaporation from a pot is slow—real humidifiers use fans to accelerate the process. Second, the volume of air in a typical room is too large for a single pot to noticeably affect. Third, the AC continuously removes any added moisture, creating a cycle where you add a drop and lose a bucket. Finally, even though ACs have airflow, they are designed to maintain stability, so any extra humidity is quickly absorbed.
Does the Viral Hack Hold Up?
It is not complete nonsense. You might get a tiny uptick in humidity, especially in a small space if the AC is not on full blast. However, it will not solve dry skin or cough problems. The hack is essentially wishful thinking rooted in real science but ineffective for modern, air-conditioned rooms.
When Might It Actually Work?
If you have a very small, sealed room and the AC is barely running, you might notice a slight difference, especially if you use multiple pots, bowls, or a wet towel to maximize the water surface area. Even then, do not expect dramatic results.
What Actually Helps for Dry Air?
For effective humidification, consider an electric humidifier, which releases much more moisture into the room. Even a wet towel left out can outperform a pot. Indoor plants also contribute a little to humidity levels.
