The Air Purification Revolution: Upcoming Air Purifier Technologies

HEPA filters are great – they’ve been our air-cleaning heroes for a long time. But get ready, a revolution is underway!

Innovative Filtration: Could Corn Replace Petroleum in Your Air Filter?

Researchers are developing cutting-edge filtration materials.

For example, a February 2023 study found that filters made from corn protein offer several key advantages. These filters can capture incredibly small particles, similar to HEPA filters, while also removing harmful chemicals like formaldehyde – something many current filters struggle with.

Plus, they offer an environmentally friendly alternative to petroleum-based filters. New materials like nanofibers and graphene are also taking filtration to the next level, capable of trapping even the tiniest particles, including some viruses.

Beyond Filtration: Chemical Decomposition by NCCO Tech

Traditional air purifiers often focus on trapping pollutants within filters. However,  a new wave of technologies aims to go further,  actively breaking down or transforming pollutants into harmless substances.

Let’s look at a prime example of this innovation:

What is Nano-Confined Catalytic Oxidation (NCCO)?

This process directly decomposes air pollutants into water and carbon dioxide using active oxygen. It offers several distinct advantages:

  • Energy Saving: No extraction or exhaust systems are needed.
  • Cost-Efficient: NCCO reactors don’t have the saturation problems of activated carbon filters.
  • No Secondary Pollution: Pollutants aren’t just trapped, but broken down.
  • Wide-Ranging Effectiveness: Works against airborne organisms, VOCs, chemicals, particulate matter, and more.
  • Environmentally Friendly: Less solid waste and recyclable materials.

The primary drawback of NCCO is a higher static pressure drop across the reactor.

Filterless Innovations: Is This the Future of IAQ?

Could the future of clean indoor air be filterless? Innovations in air purification are moving beyond simply trapping pollutants. New technologies actively target harmful substances, transforming or removing them entirely. Let’s explore two exciting examples of this shift:

How Does Cloud-Air-Purifying (CAP) System Work?

Forget traditional filters! The CAP air purifier employs cutting-edge technologies to clean your air. Here’s how this innovative system works:

  1. Heterogeneous Condensation: The CAP creates a supersaturated water vapor environment. This causes fine particles in the air to act as condensation points, making them grow larger and heavier.
  2. Supergravity Collection: The enlarged particles are then subjected to a supergravity field, which forces them to settle and be collected.
  3. Disinfection: The CAP combines ultraviolet (UV) light and a disinfectant (ClO2) to neutralize bioaerosols like bacteria and viruses actively.

Proven Effectiveness

Tests show the CAP system boasts a high clean air delivery rate (CADR) and excels at removing fine particulate matter (PM10 and smaller):

  • Particulate Removal: Removes 93% of PM10 and 91% of particles between 0.5–1 μm within 60 minutes, significantly outperforming natural decay.
  • Disinfection: Achieves a 99.99997% reduction in bioaerosols in just 20 minutes, demonstrating remarkable effectiveness against airborne pathogens.

Water-Based Air Purification Technology: Is This The Best Innovation In IAQ?

A new water-based air purification technology, called ISCLEANAIR’s APA system, represents a significant advancement in filterless air purification methodologies. Traditional air purification often relies on HEPA filtration, which necessitates costly filter replacements and can be ineffective against certain pollutants.

APA technology offers a compelling alternative due to its unique design and multi-faceted purification process.

Mechanism of Action

The APA system employs a three-stage purification process:

  1. Gas-Fluid Mixing: Ambient air is drawn into a chamber and mixed with water to create a slurry. This initial process traps pollutants within the water.
  2. Shower Scrubber: The slurry is passed through a shower scrubber for further pollutant removal.
  3. Wet Deposition & Absorption:  A patented “depositions stack” system promotes pollutants’ final precipitation and absorption, maximizing overall efficiency.


APA technology demonstrates a broad spectrum of effectiveness:

  • Particulate Matter:  Removes a wide range of particulate matter, including ultrafine nanoparticles known for their health risks.
  • Chemical Pollutants:  Capable of scrubbing various gaseous pollutants from the air.
  • CO2 Reduction:  Recent tests indicate the potential for direct CO2 capture, making it an intriguing solution for addressing climate change concerns.
  • Viral and Bacterial Disinfection:  The optional UVX enhancement provides additional protection against airborne pathogens.

Environmental Impact

APA technology aligns strongly with environmental sustainability principles:

  • Filterless Design: Eliminates the waste and cost associated with traditional filter replacements.
  • Safe Byproduct:  The system produces a simple liquid byproduct resembling rainwater that can be safely integrated into existing wastewater systems.

Potential Applications

The versatility of APA technology lends itself to diverse applications:

  • Urban Environments: Integrating public infrastructure such as lampposts, bus stops, or urban furniture can improve air quality in high-traffic areas.
  • Industrial Settings: These can be incorporated into existing industrial facilities to reduce emissions and improve working conditions.
  • Indoor Air Quality: Smaller-scale APA systems could be developed for homes and offices.

This technology offers a promising solution for indoor and outdoor air pollution challenges. Its filterless design, wide-ranging effectiveness, and environmentally conscious approach position it as a strong contender in the rapidly evolving air purification market.
