3 - SANITIZING CHAMBER

In the upper part of the filter we have a chamber, where the AIR, after the mechanical filtration phase, passes at low speed and remains for the minimum time necessary to receive a dose of ultraviolet radiation and inactivate possible pathogens that had passed through the previous phase.

The upper part of the filter has a lid, where we have access to the disinfection chamber where the air circulates and where personal objects can be placed to inactivate pathogens.

A minimum time of 2 minutes for exposing personal items to a sufficient dosage of UV-C (265nm) and inactivation of pathogens such as SARCOV2.

HEPA is a type of pleated mechanical air filter. It is an acronym for "high efficiency particulate air [filter]". This type of air filter can theoretically remove at least 99.97% of dust, pollen, mold, bacteria, and any airborne particles with a size of 0.3 microns (µm). The diameter specification of 0.3 microns corresponds to the worst case; the most penetrating particle size (MPPS). Particles that are larger or smaller are trapped with even higher efficiency. Using the worst-case particle size results in the worst-case efficiency rating (i.e. 99.97% or better for all particle sizes).

ULTRAVIOLET

UV-C radiation has a rich history in the field of disinfection. Dating back to the early 20th century, scientists discovered the germicidal properties of UV-C light and its ability to effectively destroy microorganisms.

In the 1930s, UV-C radiation gained recognition for its use in water treatment, particularly in the disinfection of drinking water. Its ability to inactivate harmful bacteria, viruses, and other pathogens made it a valuable tool in ensuring safe and clean water supplies.

Over the years, UV-C radiation technology has evolved and found applications in various industries. In healthcare settings, UV-C radiation has been utilized for disinfecting hospital surfaces, medical equipment, and even air ventilation systems. Its effectiveness in reducing the spread of healthcare-associated infections has made it an essential component of infection control protocols.

In recent times, the emergence of highly contagious pathogens, such as SARCOV-2, has further highlighted the importance of UV-C radiation in disinfection. Studies have shown that UV-C radiation can effectively inactivate viruses, including coronaviruses, providing an additional layer of protection against the transmission of infectious diseases.

With advancements in technology, UV-C radiation disinfection devices have become more accessible and user-friendly. Portable devices designed for personal use, like our product, utilize UV-C radiation to disinfect and inactivate pathogens on various surfaces, including mobile devices, jewelry, and more.

UV-C radiation long-standing history in disinfection, coupled with its proven efficacy, makes it a trusted and reliable method for maintaining cleanliness and promoting hygiene. As we continue to prioritize health and safety, UV-C radiation technology remains at the forefront of disinfection practices, ensuring a safer and healthier environment for all.

The peak in UV-C wavelength with maximum disinfection performance is typically around 265 nanometers (nm). UV-C radiation at this wavelength has been found to be highly effective in inactivating pathogens, including bacteria and viruses. It is important to note that UV-C radiation can be harmful to human skin and eyes, so it should be used with caution and following proper safety guidelines in this manual and Product Label.

Bacteria and viruses proliferate by cell division based on genetic information to cause infection and illness. DNA and RNA holds the genetic information necessary for this proliferation to occur. Irradiating with UV-C changes the helix structure of DNA and RNA of held by bacteria and viruses, which can inactivate these bacteria and viruses resulting in reducing their proliferation.

SECOND

Inactivation rate of SARS-CoV-2 is 99.9% or more, when the UV Dose is 5.1mJ/cm2

The exposure chamber, where the filtered air passes and where we have the acrylic support to place personal belongings, is 40cm (15.7”) long, 25cm (9.8”) wide and 10cm (3.9”) high internally.

The UV-C irradiation doses (DD) in mJ/ cm2 for a 210 mW UV-C source at distances of 3 cm, are as follows:

Maximum distance and time of an irradiated point from the irradiation source:

3 cm

0.2s: 1.49mJ/cm2

0.5s: 3.71mJ/cm2

1s: 7.43mJ/cm2

2s: 14.85mJ/cm2

120s: 891.27mJ/cm2

Considering the internal dimensions of the chamber, we have an air volume of 10,000cm3, or 10L, or 0.01m3 and an air outlet/inlet with an area of 0.004m2.

Let's calculate the time the air volume remains inside the chamber considering an air flow of 4ms and 2m/s respectively, which consists of the maximum speed of the fan motor and half.

For flow of 4 m/s: 0.625 seconds.

For flow of 2 m/s: 1.25 seconds.

NOTE:

These are the direct results applying the data on the chamber area, flow velocity and its inlet-outlet area and the maximum distances from the UV-C irradiation sources. We will not illustrate the formulas step by step so as not to make it too long. The important thing is that the results are mathematically verifiable by anyone.

Conclusion:

The system was designed to allow the volume of filtered air inside the chamber to remain exposed to UV-C radiation for a minimum amount of time at a distance, of no more than 3 cm and to allow a dosage greater than 5.1 mJ/cm2 at the maximum speed of the fan motor. The lower the speed, the greater the efficiency in terms of the time that the volume of air will remain inside the chamber exposed to the UV-C dosage.

For items to be placed inside the chamber, under the support, the suggested minimum time of 120 seconds is much longer than enough for the items to receive the necessary dosage to disrupt the virus's DNA/RNA.

TECHNOLOY AND CIENTIFIC ARTICLES

What is a HEPA Filter Technology

HEPA (High-Efficiency Particulate Air) filters have a rich history dating back to the 1940s. Originally developed during World War II to protect scientists and workers from radioactive particles, HEPA filters quickly gained recognition for their exceptional filtration capabilities.

The development of HEPA filters was a collaborative effort between the United States Atomic Energy Commission and the Department of Energy's Manhattan Project. These filters were initially designed to capture and contain airborne radioactive particles, ensuring the safety of personnel working on nuclear research and development.

Over time, HEPA filters found applications beyond nuclear facilities. Their ability to effectively capture and remove particles as small as 0.3 microns in size made them invaluable in various industries, including healthcare, pharmaceuticals, aerospace, and more.

HEPA filters became widely used in hospitals, laboratories, cleanrooms, and other environments where maintaining clean and sterile air is crucial. Their high filtration efficiency made them instrumental in preventing the spread of airborne diseases, allergens, and other harmful particles.

Today, HEPA filters are an integral part of air purifiers, HVAC systems, vacuum cleaners, and other devices aimed at improving indoor air quality. They continue to be recognized as one of the most efficient and reliable methods for removing airborne contaminants, including dust, pollen, pet dander, mold spores, and even certain bacteria and viruses.

The evolution of HEPA filters has led to advancements in filter technology, such as the incorporation of additional layers, electrostatic charges, and antimicrobial treatments. These innovations further enhance their filtration capabilities and contribute to healthier indoor environments.

HEPA filters have come a long way since their inception, and their impact on air quality and human health cannot be overstated. Their continued development and utilization ensure that we can enjoy cleaner and safer air in various settings, promoting overall well-being and comfort.

What is UV-C technology

Different Technologies

The main difference between UV-C radiation from Hg and Halogens lamps and LED technology lies in the way they generate and emit ultraviolet (UV) energy. UV-C energy from Hg Lamps: Hg lamps, also known as mercury lamps, have been traditionally used to generate UV-C radiation. These lamps contain mercury vapor that, when electrically stimulated, emits UV-C radiation. The emitted energy consists of a broad spectrum of wavelengths, including the desired UV-C range. Hg lamps are known for their high intensity and effectiveness in disinfection applications.

LED Technology: LED (Light Emitting Diode) technology, on the other hand, is a more recent development in UV-C radiation generation. LEDs are semiconductor devices that emit light when an electric current passes through them. UV-C LEDs are specifically designed to emit energy in the UV-C range. LED technology offers several advantages over Hg lamps, including:

1. Energy Efficiency: UV-C LEDs are more energy-efficient compared to Hg lamps, consuming less power while still providing effective UV-C output. 2. Compact Size: UV-C LEDs are smaller and more compact, making them suitable for integration into various devices and applications. 3. Instant On/Off: LEDs can be turned on and off instantly, allowing for precise control and immediate disinfection when needed. 4. Durability: LEDs have a longer lifespan compared to Hg lamps, reducing the need for frequent replacements.

Shield Guard, after extensive research, decided to use LED technology due to the advantages highlighted above, in relation to Hg and Halogen bulbs. We chose a reputed (STANLEY ELECTRIC) manufacturer with the necessary certificates stated below.

How works an AIR Purifier?

Air purifier works by removing airborne contaminants, such as dust, pollen, pet dander, mold spores, and even certain bacteria and viruses, from the air. Here's how it typically works:

1. Air Intake: The air purifier draws air from the surrounding environment through an intake mechanism, such as a fan or suction system.

2. Filtration: Once the air is drawn in, it passes through a series of filters designed to capture particles and pollutants. The most common types of filters used in air purifiers include:

- Pre-filter: This initial filter captures large particles like dust, hair, and lint, preventing them from clogging the main filter and prolonging its lifespan.

- HEPA (High-Efficiency Particulate Air) Filter: HEPA filters are highly effective at capturing small particles, including pollen, pet dander, mold spores, and some bacteria and viruses. They can remove particles as small as 0.3 microns with an efficiency of 99.97% or higher.

3. Purified Air Output: After passing through the filters, the purified air is released back into the environment, providing cleaner and fresher indoor air.

Overall, air purifiers help improve indoor air quality by reducing the concentration of airborne pollutants, allergens, and pathogens, creating a healthier and more comfortable living environment.

MPORTANT TO HIGHLIGHT

The architecture of this technology considers that the renewal of AIR continues to occur and the new AIR enters the environment through the ventilation fans, betraying contamination of the central heating or air conditioning and other environments of the residence where there may be contamination

How works a Shieldguard Closed Circuit?

Shieldguard Closed Circuit CANNOT be compared to Air Purifies.

The architecture of an AR circulation system in Canada has a central system with the furnace/conditioned air and the air flow is distributed throughout all rooms of the residence and returns to the central. This cycle continues and external air is added to promote the necessary air exchanges inside the residence. Analyzing this architecture, it appears that we have two sources of permanent contamination. Firstly, coming from external air (obligatory air exchange) and secondly, coming from other rooms where there may be a source of contamination (a person with a cold, for example).

So, if the central furnace/air conditioning filter in the basement is not of high quality and previously maintained, contamination will continually be spread throughout the residence. For example, in the pollen season, pollen comes from the external environment passing through the filter in the basement and a good amount of this contaminant will be distributed throughout the home due to the dynamics of the system. The same analogy applies to soot, dust, and all types of micro-particles.

An air purifier will filter out some of this contamination, but the contamination will continue to enter through the vent floor fans. Those people close to the AIR purifier's AIR outlet will be able to breathe good quality AIR, but outside the reach of the AIR outlet they are subject to breathing mixed AIR.

ShieldGuard closed circuit captures AIR directly from the fan floor vents, filters the air and releases it into the environment with an exchange rate higher than the room's required capacity. In this way, a positive pressure is created and the excess air returns to the central system through the air suction inlets and also leaves under the spaces under the doors to other rooms.

Our architecture creates absolutely clean air through filters and C-band ultraviolet radiation and this air returns to the central unit, ensuring that this cycle of clean air reaches the other rooms of the residence over time. However, the room where the Shieldguard filtration system is installed becomes an absolutely airtight room for any external contaminated air.

See the particle measurements before and after the filter in the photo gallery section

DOES IT SEEM SIMPLE analyzing it like this?

So, those people with respiratory syndromes, allergies to pollen and other allergic agents have at their disposal a specially engineered solution capable of keeping their environment, be it a bedroom or work environment, absolutely clean of pollutants and pathogens.

Professional solutions for domestic use.

Together we achieve extraordinary.

ShieldGuard Particle MATTER

Clean rooms are classified based on the concentration and size of airborne particles in a cubic meter of air. The levels of particulate matter (PM) for different sizes, such as PM2.5, PM1, PM0.5, and PM0.3, can vary depending on the clean room classification standards. The most widely used standards for clean rooms are ISO 14644-1 and the Federal Standard 209E. Here’s a summary of the particle count limits for various clean room classes according to ISO 14644-1:
