How safe are you with the air you breathe at home, even with an air purifier?

World-renowned Oxford University Senior researcher reveal: How DNO technology can keep families safe at home — capture, destroy and convert pollutants, bacteria and viruses (even corona virus!)

Studies have shown that indoor air quality can be 10 times worse than outdoor. This means that the air we breathe at home is full of pollutants, bacteria and even viruses!

You probably already know how most air purifiers in the market promise to remove up to 99.9% of pollutants.


Are they really effective?

You see, while the standard air purifier can trap contaminants, do you know that many of them also release harmful pollutants and gas into your home?

A particularly dangerous one is ozone — just by inhaling a tiny amount can cause chest pain, coughing, shortness of breath and throat irritation.

Prolonged exposure can aggravate respiratory diseases like asthma, weaken the body's immune system, and may even cause permanent lung damage! Not to mention the current situation of COVID-19.

This shouldn’t be the case…

This is why we have developed this ground-breaking DNO technology, which will capture, destroy, and convert pollutants, bacteria, and viruses known to pass through HEPA13 filters into harmless byproducts such as water and carbon dioxide.

Yes, that includes destroying coronavirus and Ozone!

Get access to the air quality you breathe at home

How do you know if your air purifier is doing its job of purifying the air?

The HealthyAir Purification system has a sensor that measures the air quality at home, which measures PM2.5 levels, humidity and temperature!

And yes, our air purifier does not produce toxic gases unlike ioniser or UV light!

What is D-Orbital Nano Oxide (DNO) Technology

DNO technology is the result of a collaborative effort by scientists and doctors at the University of Oxford.

Having 8 patented technologies that have been scientifically proven to destroy 99.99% of harmful particles, it will prevent harmful ozone from going back to the atmosphere. In fact, all the particles are destroyed and converted into byproduct of water and carbon dioxide!

DNO technology air purifiers are used in hospitals such as Nightingale Hospital, which cares for COVID19 patients and the Le Louvre Museum in Paris to protect visitors during viewings.

Here’s how it can provide you odourless, clean air with our 4-step filtration process

Stage One:

Primary Filter 

The polluted air, viruses and germs first go through this easy to remove filter that prevents the internal filters from being "clogged" through large particles.

Stage Two:

Medical Grade HEPA (H13) Filter

Our combined HEPA filter uses two medical-grade HEPA (H13) filters in sequence, removes 99.95% of particles at 0.1 microns or larger.

It also traps large particles present in every home, such as pollen, dust and animal dander.

Stage Three:

DNO Filter

An airborne particle that sneakily passes through the HEPA filter is destroyed after contact with our patented DNO catalytic filter.

The technology is designed to destroy all biological and chemical pollutants such as H1N1 Virus (influenza A), Coronavirus 99.99% and 99.89% of harmful Ozone layers!

Stage Four:


What about the airborne particles that escape through? Well, this is exactly why we use an ionizer — sending them back to the DNO filter to destroy the pollutants.

As a result, the air purifier emits clean, safe, and healthy air that families can enjoy, relax and breathe without worrying about harmful gases or health risks.

Remember how it feels like breathing fresh air in nature or parks before COVID19? This is as close as it gets!
