Range Hood Filter

Range hood grime

is not just oil stains.

Oil and dust,

and fine particles that rise during cooking, mix together,

and over time transform into stubborn grime that is difficult to remove.

We are

a professional cleaning company

that sees this grime every day on site.

So we thought.

Of a way to prevent dirt before it even gets there.

Air passes through.

Dirt does not pass through.

The filters from Kuki no Osama (King of Air)

are the answer created by cleaning professionals who put their heart into it.

3 reasons from a cleaning professional

[Feature 1] Designed by cleaning professionals who understand dirt inside and out
Kuki no Osama's range hood filters are

made by a company that understands the cleaning process,

with a track record of over 1 million units sold.
We understand how grease and smoke generated during cooking

enter the range hood

and where dirt accumulates.
With this understanding, we designed our filters based on the idea of preventing dirt before it accumulates.
[Feature 2] Structure that ensures ventilation while preventing dirt from passing through
There's no point if ventilation efficiency is compromised.

But there's also no point if dirt gets through.
Kuki no Osama filters have gone through repeated trials and errors to achieve both.

Air passes through smoothly,

while dirt like oil and dust are firmly captured.
[Feature 3] Reduce cleaning effort by simply replacing
When it gets dirty, simply replace it.

That's what the King of Air's range hood filter is all about.
There's no need to clean the interior or fan

every time.
By replacing it with a perfectly fitting dedicated frame,

the filter effectively catches dirt,

and prevents dirt from entering the interior.
As a result,

it reduces the frequency of troublesome disassembly and cleaning,

and lightens the burden of daily cleaning.

Because it's a place you use every day, we also pay attention to the materials.

Standard fiberglass filters can produce a strong, irritating odor when exposed to high temperatures or oily smoke.

Depending on the usage environment, there may also be concerns about material degradation or fine fibers.

Filters from Kuki no Osama address these concerns by using materials that do not contain fiberglass.

Because the kitchen is used every day, the design considers odor, air quality, and the peace of mind of the user.

AT254 Antibacterial and Antiviral Filter

The photocatalytic air catalyst AT254

is a technology that reacts with water and oxygen in the air,

and is expected to suppress the spread of bacteria and viruses.

We process this AT254 into

air conditioner filters, air intake filters, and ventilation filters.

These are places that

take in and circulate air.

They are constantly connected to

people's living spaces through the air.

That is why they

work continuously day and night,

without the need for special operations or power.

They do not obstruct airflow

and blend naturally into the space.

The various filters processed with AT254 were created

as an option for maintaining a healthy daily air environment.

Three Features of AT254

[Feature 1] Air catalyst reacts with air and continues to work for 24 hours
Filters treated with the AT254 air catalyst are also attracting attention as a measure against airborne infections.
The AT254 air catalyst is a technology that acts on bacteria and viruses contained in dust adhering to filters.
By reacting with moisture and oxygen in the air and continuously carrying out a catalytic reaction 24 hours a day, it is expected to suppress the growth and spread of bacteria and viruses.
Additionally, it breaks down harmful substances in the air that may endanger health into water and carbon dioxide.
Another feature is that it does not require light or electricity, and can be effective anywhere, regardless of location or time of day or night.
[Feature 2] Effectiveness verified by a third-party organization: Proven to suppress the activity of bacteria and viruses
AT254 has been shown to be 99.88% effective against bacteria and viruses in tests conducted by

a third-party organization.

It is expected to act on bacteria and viruses

contained in dust adhering to the filter,

suppressing their proliferation and spread.
This is why it is attracting attention as a measure against airborne infections.

*The test results are data under specific conditions and

do not guarantee the same effect in all environments.
【Feature 3】SIAA-certified antimicrobial and antiviral treatment
AT254 is an antibacterial and antiviral processing technology

that has received SIAA (Society of Industrial Technology for Antimicrobial Articles) certification.
Tests conducted by third-party organizations have confirmed a 99.88% effectiveness against bacteria and viruses.
It is expected to act on bacteria and viruses

contained in dust that adheres to the filter,

suppressing their proliferation and spread.
This is why it is attracting attention

as a measure against airborne infections.
*The test results are data under specific conditions,

and do not guarantee the same effect in all environments.

*SIAA certification indicates that the product as an antibacterial and antiviral processed product

　meets safety and proper labeling requirements.

Numerous case studies in public facilities and public transportation

AT254 coating, with its properties of being

colorless, transparent, and not affecting the finish, while also not requiring UV light or any light source,

is used in public facilities, public transportation, and other places

frequented by many people.

A key feature is that the appearance does not change after application,

allowing it to be used without compromising the aesthetics of vehicle interiors or facilities.

Furthermore,

since it does not require UV irradiation or a power source,

it is easy to use in spaces that are in operation, day or night,

and is therefore utilized as one of the daily measures for air quality control.
