WHAT IS UVC LED AND NEGATIVE ION STERILIZATION? THE DIFFERENCE BETWEEN THE TWO STERILIZATION TECHNOLOGIES IN ACERPURE AIR PURIFIERS

Nowadays, the problem of environmental pollution is becoming increasingly complex, leading to a rise in airborne viruses and bacteria. There are two technologies that help eliminate bacteria: UVC LED technology and negative ion technology. Let's learn about these two technologies in the article below:

OVERVIEW OF UVC LED STERILIZATION TECHNOLOGY

2. WHAT IS UVC LED TECHNOLOGY?

UVC rays are the type of UV rays with the shortest wavelength (from 100 to 280 nm), which are highly effective in killing viruses and bacteria. However, caution is required because this is the group of light rays with the highest energy and is the most dangerous among other UV groups; if exposed directly for a long time, it can cause harm to skin and eyes. Currently, this technology has been researched and widely applied for integration into products such as air purifiers, water purifiers, etc., to provide effective sterilization capabilities. The Acerpure Cool C2-UVC air purifier and the Acerpure Pro P2 air purifier are currently integrated with this technology.

2. OPERATING PRINCIPLE OF UVC LED TECHNOLOGY

UVC is a sterilization technology using radiation lamps; these lamps emit UVC rays into the air or onto the surface that needs to be sterilized. Any virus or bacteria exposed to UVC rays will have its DNA structure altered, disabling its ability to replicate and clone, and it will be destroyed quickly. The UVC technology in the Acerpure Cool C2-UVC and Acerpure Pro P2 air purifiers has been tested and proven capable of killing >99% of airborne bacteria and viruses, typically the Coronavirus (HCoV-229E) and the influenza virus aH1N1. In terms of design, the UVC lamp is located inside the body of the machine and is covered by the machine's casing, so it does not harm the health of consumers at all.

OVERVIEW OF IONS

1. WHAT ARE IONS?

An ion is a component in the air, created by the effect of electromagnetism causing atoms and molecules to lose their charge. After losing their charge, these atoms and molecules become charged particles. If a particle loses a negative charge, it leads to an excess of a positive charge, which we call a positive ion, and vice versa. In nature, ions are found in abundance during thunderstorms, lightning, or near rivers and streams. Additionally, ions can be created by humans using high voltage, typically integrated into the Acerpure Cool C2-UVC air purifier.

2. OPERATING PRINCIPLE OF ION TECHNOLOGY

Ions have been proven effective in killing bacteria and viruses. When coming into contact with bacteria and mold in the air, negative ions break down the molecular structure by removing the H+ atom on the cell membrane, thereby disabling the activity of bacteria, causing them to fall to the ground and lose their ability to cause harm.

WHAT ARE THE ADVANTAGES AND DISADVANTAGES OF THESE TWO TECHNOLOGIES?

1. STERILIZATION MECHANISM

In essence, the sterilization mechanism of these two technologies is different. UVC sterilizes by directly altering the DNA of bacteria upon contact, rendering them inactive and completely destroying them. Negative ions sterilize by breaking down the cell wall structure of bacteria and viruses, making them inactive and causing them to fall to the ground, but they are not completely destroyed. In addition, there are a few other aspects to evaluate.

2. STERILIZATION TIME

UVC LED technology will kill bacteria immediately upon contact, while negative ion technology will need time to disperse into the air at a high enough concentration to cover viruses, then deactivate them and cause them to fall to the ground. Therefore, in terms of sterilization time, UVC LED technology performs better than negative ion technology.

3. COVERAGE AREA

UVC LED requires direct contact with the surface that needs to be disinfected to provide good sterilization results, so the sterilization area is not high. Conversely, negative ions are essentially a component found in nature and are not harmful to the user's health when touched; therefore, they can be spread and dispersed in large spaces, providing better sterilization in larger spaces than UVC LED.

4. WHICH STERILIZATION TECHNOLOGY DO ACERPURE AIR PURIFIERS USE?

Currently, the Acerpure Cool C2-UVC and Acerpure Pro P2 air purifier product lines have been integrated with both UVC LED and negative ion technologies to optimize air purification capabilities. These devices are all tested and proven to be capable of removing up to 99.9% of airborne bacteria and viruses with extremely impressive speeds.
