Saying an air purifier isn’t important is like saying quality of life isn’t important.

For Rene, clean air is part of living well.
Born and raised in Jakarta, Rene Suhardono has lived with his family in a South Jakarta apartment for the past six years.
For him, the importance of air comes down to something simple. We can go days without food and hours without water. But we can’t go very long without breathing. And if breathing is something we do every moment of every day, Rene believes the quality of what we breathe deserves more attention.
That wasn’t always something he thought about at home.
Like many people, Rene used to open the doors and windows every morning. It felt intuitive: open the windows, let the fresh air in.
Living with Clean Air Zone by Nafas made him question that habit.
Instead of assuming the air outside is better, Rene can now understand what’s actually happening with the air around his home. That information has become part of how his family makes everyday decisions—when to open the windows, when to keep them closed and when to let Clean Air Zone continue protecting the air inside.
“Now we actually decide when to open the windows and doors, and when to keep them closed.”

His home tells the same story.
His home tells the same story.
Across April to June 2026, Rene’s home recorded a median indoor PM2.5 of 10.3 µg/m³, compared with 47.2 µg/m³ outdoors.
That means the air inside his home was 4.6× cleaner than outdoors across the three-month period.
And that protection held even as outdoor conditions changed significantly. Outdoor PM2.5 rose from 35.4 µg/m³ in April to 64 µg/m³ in June, while indoor levels stayed within a much narrower range of 9.7 to 12.7 µg/m³.
May was Rene’s strongest month.
His home reached a Healthy Home Score of 93.3, with indoor PM2.5 at 8.8 µg/m³ compared with 44.9 µg/m³ outdoors — making the air inside 5.1× cleaner.
But the most meaningful change isn’t just something he sees in the data.
It’s something he feels at home.

The biggest difference for Rene is at night.
The biggest difference for Rene is at night.
“If you ask me what change I’ve noticed the most, it’s the quality of my sleep.”
Rene describes better sleep as one of the changes he and his family have noticed since living with Clean Air Zone.
It has also made him think differently about the hours we spend asleep. At night, doors and windows may be closed, but that doesn’t necessarily mean the air outside stays outside. As Rene puts it, air can find its way through even the smallest gaps.
One morning made that especially real for him.
Rene woke up and saw an outdoor air-quality reading that immediately caught his attention. The conditions were poor enough to make him wonder what it would mean to spend the whole night breathing air like that without realizing it.
“If I were sleeping with air quality like this, what would that mean?”
His home’s data puts that concern into perspective. Even when outdoor conditions moved considerably from day to day, the air measured inside his home remained consistently lower in PM2.5.
In May, outdoor PM2.5 averaged 44.9 μg/m³, while his home held indoor levels at 8.8 μg/m³.
The difference wasn’t something Rene had to guess anymore. He could see it.

A Different Relationship With Home
For Rene, Clean Air Zone has changed more than the air inside his apartment. It has changed the way he thinks about it.
Something as ordinary as opening a window in the morning is now an informed decision. He can understand what’s happening around his home, know when the air inside needs protection and let the system do its job.
And at night, when he isn’t thinking about the air at all, his home can continue to stay protected.
For someone who believes that the quality of what we breathe is part of the quality of how we live, that matters.
“This probably isn’t something only I experience. It could be happening across Jakarta. But now, there’s a solution. What are you waiting for?”

Over time, checking the air became less about curiosity and more about reassurance.
Sometimes it's before heading out for the day.
Sometimes it's checking in while he's at work.
Sometimes it's simply seeing how his home responds to everyday moments, like cooking dinner or opening the front door.
"It became part of my daily routine."
The numbers didn't become another thing to worry about.
They became reassurance.
A quiet reminder that his home was doing what it was supposed to do.
