🚨 This is an urgent announcement.
"If I receive it at the end of August, is it right to fund now?"
We have also thought about this a lot.
We would like to speak honestly as we proceed with this encore.
In fact, air coolers are used more frequently after the peak of the heat wave than during it.
Air conditioner is too expensive to run all day due to the burden of electricity bills,
but a fan alone is not enough during this period.
At that time, the most effective way is to use it as a supplementary cooling device together with the air conditioner for additional cooling.
In fact, many people raise the air conditioner temperature and use the air cooler together to maintain coolness while electricity bills are reducedA method of reducing. Is being used in this way.
However, most people only start looking for the product after they need it.
And at that time, they always say the same thing.
"I should have bought it a little earlier..."
So this encore is not for those who 'need it now', but rather, for those who 'will need it soon'. This is the final preparation for them.
This Reward will beshipped sequentially from August 24th.
And after this restock, there will beno additional production or restocking planned for this summer.
Once you need it, it's already too late.
Preparation should be done not when it's hot, but just before the heat ends.





An air cooler that will freeze the entire space.
















Just before the pump draws water up and supplies it to the cooling pad,a UV-C lamp is placed in the narrowest and most sealed 'sterilization-only path'.






Instead of simply spraying water, continuously sterilized water moistens the filter, reducing concerns about bacterial growth and providing cleaner air.














The horror of midsummer, electricity bills?
Don't worry!












As water evaporates, it absorbs heat from its surroundings.'Latent heat of vaporization'This principle is utilized.
When hot air is drawn in and passes through a cold water filter, the air loses its heat and is reborn cool and moist.
It is the same natural principle as the refreshing air in the mountains after rain.



The key to cooling efficiency lies in the area and duration where air and water meet.
For these two factors, Indus rejected flat filters anddeveloped the '3D Wave' structure.

Thousands of fine honeycomb cell structures retain water densely, enabling heat exchange along every path the air passes through. This boasts overwhelming water retention and evaporation area compared to ordinary paper filters.

Indus's wave filter guides air topass through the inside of the filter in a zigzag pattern, physically increasing the time air stays on the wet surface by about1.5 times or more.

By precisely adjusting the gap between the cooling filter and pad, structural issues such as water splashing due to material deformation or water leakage along the filter have been minimized.




Indus has prepareda total of four dedicated ice packsis provided.
Use two packs in the product to create instant cooling, while the other two wait in the freezer for the next round.
This is Indus's thoughtful design to ensure that even during the brief moment of changing ice packs, the cooling does not stop.
Four ice packs just taken out of the freezer rapidly lower the water temperature in the 4L large-capacity tank, delivering powerful cooling air comparable to an air conditioner.
In addition, you can maintain coolness by using a combination of water and ice instead of ice packs.




A cooling fan is not just a machine that creates wind; it must send the cooled air 'far' to lower the temperature of the entire space.
If the wind speed is weak, the cooling effect will remain only around the device.

A powerful wind speed of 8 meters per second leaves the outletand travels straight for up to 10 meters or more.
It delivers cool air without loss from one end of a spacious living room to the kitchen, or from the foot of the bed to the headboard in the master bedroom.
And the stronger the wind speed, the faster the indoor air circulates, dramatically reducing the time it takes to reach the set temperature when used together with an air conditioner.



When reading or when a baby is sleeping, it provides a gentle breeze that softly envelops you without noise.


During daily activities or cooking, it is the most refreshing breeze to cool off your sweat.

When you return home after going out or need rapid cooling, it delivers a typhoon-level wind that chills the space in an instant.


Like a bladeless fan or a tower fan, it can be used all year round.




Instead of blowing at a single spot, it circulates the air evenly throughout the living room or office, so you can feel uniform coolness no matter where you are.


The longer you use it, the more the water in the tank becomes contaminated, which sooncauses fishy water and musty mold odors.





Just before the pump draws water up and supplies it to the cooling pad, a UV-C lamp is placed in the narrowest and most sealed 'sterilization-only path.'

As the water passes through the narrow passage, it is directly exposed to powerful UV-C energy at a very close distance.
The sterilizing rays are applied more directly to each water molecule.

Every time the water circulates, it must pass through this 'sterilization chamber.'
The longer the usage time, the more the entire tank of water is continuously purified, and only sterilized clean water is always supplied to the filter.




While regular cooling fans only manage the dust filtered by the filter, Indus goes further byreleasing cation and anion clustersto address even invisible dangers.


When operated for 120 minutes against Staphylococcus aureus, it was proven to remove 99.99% of harmful airborne bacteria.

The released plasma ions surround the surface of microorganisms and extract hydrogen ions, destroying their protein structure.
The bacteria lose their strength and disappear, turning into harmless water molecules.




Plasma ions generated inside the cooling fan care for fine particles and odors floating in the air,providing a more pleasant breeze.


Odor particles from pets, cigarette smoke, kitchen food smells, and more combine with plasma ions in the air and are chemically decomposed.


Not only that,even subtle water odors or mold spores that may occur inside the cooling fan are instantly suppressed in the air, always delivering a refreshing breeze as if you were near a forest waterfall, at all times.




As a core function unique to Indus,Water pump + 3D wave filter + 8m/s strong windoperate simultaneously in this mode. The cold water in the tank is instantly circulated throughout the entire filter, effectively lowering the air temperature.
This is a mode like 'Heart of Indus' that truly shines when used with an ice pack.



We have digitized the irregular rhythm of wind blowing in an actual forest.
Depending on the operating wind speed (gentle breeze: levels 1-3, light breeze: levels 4-6, strong wind: levels 7-8), it implements the effect of natural wind according to a set program, blowing air softly and comfortably.
The wind speed alternates between strong and weak, making it feel like the refreshing natural breeze that comes in when you open a window. Even after long use, your head does not feel heavy and comfort is maintained.


The sleep wind mode automatically adjusts the wind speed to help you sleep comfortably.
When the sleep wind mode is set, it starts operating at level 3 wind speed, and you can adjust the wind speed afterward.
1. Wind speed levels 4-8: The wind speed decreases by one level every 5 minutes. Once it reaches level 3, it maintains that state.
2. Wind speed levels 1-3: The wind speed is fixed at level 3.
It helps you fall asleep coolly at first, and during deep sleep, it automatically switches to the quietest and softest ultra-gentle breeze to prevent a drop in body temperature.
Combined with low noise under 40dB, it ensures a peaceful sleep until morning.



Set the timer in one-hour increments to use it safely for as long as you want.


Even if you turn it off and on again, it remembers the wind speed and mode you last used, saving you the trouble of resetting every time.


We have also added a child lock function to prevent settings from being changed even if a child touches it.





Press and hold the 'Wind Speed' button for 3 seconds before turning off the power.
Powerful airflow completely removes moisture from every corner inside.
Once drying is complete, the power is automatically cut off, so you can go out or fall asleep with peace of mind. This is the secret to maintaining the freshness of first use every day.




Indus provides perfect control of all functions even from a distance,Smart remote controlas a standard feature.

It smoothly receives signals even if not facing the front of the product.
Equipped with a high-sensitivity IR sensor that responds instantly, whether you are reclining on the sofa or operating it from the bedside table.



It reduces the time spent searching for the remote control when you don't know where you left it.
A dedicated storage space has been designed on the back of the main unit to hold the remote control.
Keep it neatly stored without worrying about losing it, even during off-seasons or when cleaning.













Most low-priced air coolers on the marketuse AC (Alternating Current) motorsorstandard DC motors.
However, Indus has chosen as its core theBLDC (Brushless Direct Current) motor, which was previously reserved only for high-end premium appliances.
The BLDC motor in Indus removes the brush and controls polarity with a digital circuit.
Because there is no physical friction, the motor operates with minimal noise, and with no energy loss, it can run for long periods without worrying about overheating.






AC motors have a shorter average lifespan due to friction, and their noise increases over time.
In contrast, the BLDC motor in Indus maintains its initial performance for years and has dramatically reduced the failure rate of internal components.







When you loosen the front grill screws and open the cover, the internal filter is visible first.
After removing the filter, please loosen the fixing screw at the bottom of the fan.
Next, lift the fan upward to easily detach it.

You can take the removed fan directly to the bathroom and wash it thoroughly with a showerhead..
You can wipe away even the dust stuck in the crevices. We also plan to provide assembly and disassembly instructions via a QR video.


Simply turn the bottom lever 90 degrees to smoothly open the water tank.
There is no need to unscrew or disassemble anything complicated.

With a wide opening that fits your hand, you can use a scrubber to clean away even the last bit of residue at the bottom.


A cleaning brush, useful for removing dust from narrow gaps or between pads, is included as a standard accessory.
This is Indus's meticulous commitment to 'hygiene' that you won't find in other brands.




Compared to typical box-type air coolers, the floor space required has been dramatically reduced.
As long as you have a width about the span of an adult man's hand, you can install it anywhere.


Indus becomes an interior highlight whether placed in the center of the living room or in a corner, allowing you to use your space more efficiently.

Place it at the head or foot of your bed, or in any narrow gap.
It delivers a refreshing coolness that enhances your sleep quality without taking up space.

Even in narrow kitchen aisles, Indus's powerful airflow instantly cools you down while you cook, without getting in the way.

It fits perfectly into tight spaces.
The quietness of the BLDC motor and the slim design maintain a comfortable temperature without disrupting your focus.


When the lower tank is filled with water, the center of gravity shifts downward,low center of gravity designhas been applied.
It boasts solid stability with minimal vibration during rotation and is not easily knocked over even if accidentally bumped.




The matte body of Indus is resistant to stains that occur during use, and its smooth, sturdy feel proves it is a premium appliance.

It blends naturally into any style of space, whether it is mid-century modern, Scandinavian sensibility, or minimalist interior, without standing out.
Just like furniture that has been there from the very beginning.


A black panel that allows you to control all functions with just a light touch is placed at the top.
It is designed at the optimal angle so you can operate it without having to bend deeply at the waist.

Current mode, wind strength, and timer status are displayed with intuitive LED icons.
The LED turns off at night to prevent eye fatigue.


It is designed by calculating the ideal height and air outlet range so that the breeze reaches your body most efficiently whether you are sitting on the sofa or lying in bed.
It embodies Indus's philosophy that design is only complete when it follows function.
