Air Monitoring and Purification in Buildings
A patent by AL Filters provides air filtration and purification in enclosed spaces using impregnation technology, where metallic molecule complexes of silver or zinc are embedded into the fibers of the filter fabric. This process grants the fabric inherent antibacterial and antiviral properties, along with enhanced particle capture efficiency
The fabric enables upgrading any basic air conditioner into a microbial air purifier without releasing chemical substances
into the air.
This unique solution offers an excellent cost-benefit ratio and flexible installation, allowing the treated filter fabric to transform any standard air filter into an effective trap and eliminator of bacteria, mold, and viruses. The fabric has been tested and proven to be both effective and safe for use.
This is a groundbreaking product in the field, with research-backed performance, based on academic studies conducted at Bar-Ilan University.
?What Does the System Include
Additionally, the technology can be applied to any type of filter, enhancing its filtration and purification capabilities. The company also offers specialized equipment and complementary accessories as needed.
About the Distributor – Air-Qualitee
The Air-Qualitee brand specializes in air treatment solutions, distributing AL-Group's air filtration products as well as Rad Green's air quality monitoring solutions.
About the Manufacturer – A.L. Group
With over 60 years of expertise, the company specializes in the development, manufacturing, marketing, and industrialization of filtration products for various spaces and vehicles.
A.L. Group employs over 1,450 people and has representatives in multiple countries, including the U.S., China, Bulgaria, and Japan. The company operates professional laboratories dedicated to developing products that meet leading industry standards and market demands.
The manufacturing facility holds quality certifications such as ISO 14001, ISO 9001, and more.
Three Key Features of the Product (Based on SID Research Findings):
1. Unique Flexibility and Ease of Installation – The treated fabric can be purchased, cut to size, and inserted into any device, instantly enhancing filtration and purification capabilities. The installation process is quick, simple, and requires no special tools, allowing for immediate operation.
2. Excellent Cost-Effectiveness – This system is easy to install and comes at an attractive price compared to alternatives. Unlike other solutions, no additional external components are required—only the treated filter fabric itself. This results in significant cost savings compared to upgrading or replacing existing air filtration systems. (More details on cost-effectiveness are provided later in the review.)
3. Energy Efficiency – According to company findings, the technology enables upgrading a filter from MERV 8 to a high virus-capturing efficiency surpassing MERV 13, without altering its original particle filtration properties. This maintains airflow efficiency, reducing energy consumption and installation costs while avoiding the higher expenses associated with using a standard high-MERV-rated filter.

:How to Use IN-EX
The result is cleaner indoor air. The treated fabric should be replaced periodically as part of the standard maintenance routine for the air conditioning or ventilation system.
The system operates normally – as air flows through the treated fabric, it captures and destroys airborne pollutants.
The treated fabric is easily installed onto the HVAC filter, with no need for professional skills or tools.
The product is suitable for a wide range of applications
Use in residential air conditioners and ventilation systems
Integration into commercial HVAC and HEPA filters
Application of IN-EX in portable filters
Use in commercial vehicles and buses
IN-EX for automotive applications
Example of a Simple and Quick Installation in a Home Air Conditioner
Cover approximately 25%–30% of the filter surface with the treated IN-EX fabric. It is recommended to replace the IN-EX fabric with each periodic cleaning or washing of the air conditioner's filter.
This simple step effectively upgrades any standard air conditioner and filter into an efficient contaminant trap and neutralizer.

How It Works?
IN-EX uses Sono-Chemical Technology (SCT), originally developed for the pharmaceutical industry. This technique embeds (impregnates) metallic ions (zinc and silver) into the fibers using ultrasonic waves.
Two Key Advantages of This Method:
- The metals are tightly bound to the fabric and do not release into the air.
- The product retains long-term disinfection efficacy, outperforming other technologies.

Tested and Verified
Laboratory & Academic Testing:
The product has been tested for its effectiveness in treating and eliminating various bacteria and viruses, and has demonstrated high efficacy in multiple laboratories and test protocols. Below are examples of certifications (full documentation is attached in the appendices).
Bar-Ilan University (Israel):
Significant bacterial reduction (E. coli, S. aureus)
Vismederi TEXTYLE (Italy):
>99% reduction of Influenza A1N1 in 6 hours (ISO 18184)
MSL (UK):
99.99% bacterial reduction (ISO 20743)
Return on Investment (ROI)
Up to 20x ROI compared to traditional filtration system upgrades:
- Avoided system upgrades: MERV-8 filters can be upgraded to MERV-13-level virus protection with minimal investment.
- Energy savings: MERV-8 filters have ~10% lower energy demand than MERV-13.
- Lower filter costs: IN-EX treated filters cost ~30% less than MERV-13 equivalents.
Sustainability and Green Building
Improving Indoor Air Quality
Studies show that people spend approximately 90% of their time indoors. Therefore, enhancing indoor air quality is crucial for maintaining health and well-being.
Installing an IN-EX filter enables cost-effective upgrades to existing HVAC systems, significantly reducing viral and bacterial contamination. This leads to healthier indoor environments without the need for expensive system replacements.
An Innovative and Groundbreaking Product
This is a patented product developed by A.L. Group. Therefore, a project that incorporates this solution is expected to earn points under the Innovation category of the Green Building Standard.
See the potential green building credit table further below.

Option to Integrate Air Quality Monitoring Sensors
Air-Qualitee distributes air quality sensors developed by RadGreen. These sensors monitor a wide range of environmental parameters and enable user control over various ventilation and HVAC systems.
Projects that implement the RadGreen system are eligible for green building credits (according to Israeli Standard 5281) due to the integration of monitoring and control capabilities—see the potential credit table below.
Real-time air quality monitoring and display allows for immediate responses to malfunctions, ensures consistently high indoor air quality, and contributes to energy savings. This is especially important for HVAC systems, which consume significant energy for climate control and must be continuously monitored.
ISO 14001 is an international standard for Environmental Management Systems (EMS). It is designed to help organizations identify, manage, and improve their environmental impact while ensuring compliance with legal requirements and promoting continuous improvement in environmental performance.
Compliance with this standard demonstrates the organization's commitment to sustainable and environmentally responsible operations.
