Active air purification: how ActivePure® technology treats air and surfaces
Active air purification is a category of air treatment technology designed to address airborne contaminants as air moves through a space. Unlike traditional filtration, which relies on physically capturing particles in a filter, active air systems work by treating contaminants within the air itself.

The basics
How active air purification works
Unlike passive filtration, which captures particles only when air passes through a filter, active air systems work continuously to treat contaminants in the air itself.
This approach allows active air purification to complement traditional filtration by addressing areas of a home where filtration alone may be limited.
- Works continuously
- Treats the air itself
- Complements filtration
Understanding how this technology works, and where it fits, helps homeowners make informed decisions about indoor air quality.
The technology
ActivePure® technology explained
ActivePure® is a patented active air purification technology used in select residential air purifiers. It is designed to operate continuously as air moves through a system or room, helping treat airborne contaminants rather than relying solely on physical capture.
ActivePure® technology is used as a supplement to filtration, not a replacement. In properly designed systems, it is paired with mechanical filtration to support a broader indoor air quality strategy.
ActivePure® is the technology behind the Aerus line, and Platinum Air Care is an authorized dealer.

Active air purification vs HEPA filtration
HEPA filtration and active air purification serve different purposes.
Captures particles
HEPA filtration
HEPA filtration works by physically trapping particles as air passes through a dense filter. This is highly effective for particulate removal but only treats air that flows through the filter.
Treats the air in the space
Active air purification
Active air purification works by treating air as it circulates through a space, allowing it to address contaminants beyond a single intake point.
For this reason, many homes benefit from using both technologies together.

Beyond the air
Surface protection and environmental treatment
One of the defining characteristics of ActivePure® technology is its ability to extend beyond airborne treatment. Active air purification systems are designed to reduce contaminants not only in the air, but also on surfaces within treated spaces.
This concept, often referred to as environmental or surface treatment, allows active air technology to support cleaner indoor environments by addressing areas where airborne contaminants may settle.
It is an added layer alongside regular cleaning and filtration, working continuously while air circulates through a space.
Where it comes from
The origins of ActivePure® technology
ActivePure® technology traces its origins to research initiatives associated with NASA. Early forms of this technology were developed to help address air quality challenges in controlled environments.
The technology has since evolved for residential and commercial applications, and in 2017 it was inducted into the Space Foundation’s Space Technology Hall of Fame, highlighting its significance in applied environmental innovation.
That recognition reflects the scientific foundation behind the technology’s development.

Is it right for you?
When active air purification makes sense in a home
Active air purification is typically considered in homes where:
- Air circulates continuously through HVAC systems
- Windows remain closed for extended periods
- Whole-home coverage is desired
- Supplemental treatment is needed alongside filtration
Active air technology is most effective when evaluated as part of the whole system.
Not sure?
Which combination of active purification and filtration suits the house depends on the layout and how the air actually moves through it.

Guardian Air systems
Active air purifiers using ActivePure® technology
Platinum Air Care offers air purification systems that incorporate ActivePure® technology in different formats, depending on how air moves through the home and where treatment is needed.
Furnace-mounted active air purifier
Guardian Air Home
Guardian Air Home is a furnace-mounted active air purification system that uses ActivePure® technology designed to treat air as it circulates through the HVAC system. Installed at the equipment level, it operates whenever the heating or cooling system runs, supporting air treatment throughout the entire home.
Guardian Air Home uses high-efficiency filtration in conjunction with ActivePure® technology to provide whole-home coverage.
Portable active air purifier
Beyond Guardian Air
Beyond Guardian Air is a portable air purifier that uses ActivePure® technology for targeted, room-level air treatment. It is designed for bedrooms, offices, or spaces where duct access is limited.
Portable active air units are often used to supplement whole-home systems or to address specific areas of concern within a home.

Our approach
How Platinum Air Care approaches active air purification
Platinum Air Care evaluates active air purification as part of a broader indoor air quality strategy. Every home is assessed individually to determine whether active air technology, HEPA filtration, portable units, or a combination of approaches is most appropriate.
The focus is on education, proper application, and long-term performance rather than one-size-fits-all solutions.

Questions
Common questions about active air purification
What is active air purification?
Active air purification is a category of air treatment technology designed to address airborne contaminants as air moves through a space. Unlike traditional filtration, which relies on physically capturing particles in a filter, active air systems work by treating contaminants within the air itself.
What is ActivePure® technology?
ActivePure® is a patented active air purification technology used in select residential air purifiers. It is designed to operate continuously as air moves through a system or room, and it is used as a supplement to filtration. ActivePure® is the technology behind the Aerus line, and Platinum Air Care is an authorized dealer.
Is active air purification better than a HEPA filter?
They serve different purposes. HEPA filtration works by physically trapping particles as air passes through a dense filter, which is highly effective for particulate removal but only treats air that flows through the filter. Active air purification treats air as it circulates through a space. For this reason, many homes benefit from using both technologies together.
Does ActivePure® treat surfaces as well as air?
Yes. Active air purification systems are designed to reduce contaminants not only in the air, but also on surfaces within treated spaces. This is often referred to as environmental or surface treatment. It is an added layer alongside regular cleaning and filtration.
Is ActivePure® NASA technology?
ActivePure® technology traces its origins to research initiatives associated with NASA. It has since evolved for residential and commercial applications, and in 2017 it was inducted into the Space Technology Hall of Fame, a Space Foundation program.
How much does an ActivePure® system cost?
It depends on the equipment and on the house — a portable and a furnace-mounted install are not the same job, and what suits one home is wrong for the next. That is what the free in-home air test is for, and it costs nothing through Platinum Air Care.
