PuraWard sterilization and antiviral technology analysis:

PuraWardPurafil technology is a product that combines antimicrobial technology with chemical fibers. It has various practical bactericidal and antiviral effects, such as effectively removing SARS virus 99.58%, H1N1 virus 99.91%, and H7N9 virus 99.98%, and has passed multiple certifications.

1、 The principle of "silver+copper" ion mixture sterilization and antiviral:

PuraWard technology can achieve good results in sterilization and antiviral treatment due to its proprietary "silver+copper" ion mixing technology. Under the combined action of silver ions and copper ions, bacteria and viruses will be attacked and eliminated with the following effects:

Step 1:PuraWard fibers release a large amount of copper and silver ions, which work together to attack bacteria and viruses.

Step 2:Copper ions are adept at attacking proteins/amino acids in bacterial and viral cell walls, creating conditions for silver ions to enter cells.

Step 3:Silver ions are good at entering the cytoplasm and reacting with the DNA of bacteria and viruses, leading to the denaturation of DNA structure. Obtain the following effects:

Antibacterial effect:Due to the denaturation of DNA structure, it inhibits DNA replication, resulting in viruses and bacteria being unable to divide and reproduce, causing them to lose their vitality.

Suffocation effect:Due to the destructive effect of silver ions, respiratory enzymes in the cytoplasmic matrix of viruses and bacteria become ineffective, leading to their death.

Lack of food effectDue to the reaction between silver ions and bacterial proteases, viruses and bacteria are unable to metabolize energy and are subsequently killed due to lack of food.

Step 4:PuraWard fibers produce substances with low pH values on the surface of the fibers. A low pH environment can alter the three-dimensional structure of the virus's "protein shell", causing irreversible denaturation of the protein's spatial structure, thereby causing the virus to lose its ability to bind to host cell receptors and achieve the effect of inhibiting viruses and bacteria.

2、 Description of PuraWard's sterilization and antiviral technology characteristics:

Feature 1: Effective sterilization:PuraWard's "silver+copper" ion mixing technology can effectively kill 99.9% of target bacteria and viruses. And it has passed three certifications on sterilization efficiency conducted by MICROBAC (International Microbiology Laboratory of the United States), with an atypical pneumonia (SARS) virus inhibition rate of 99.58%, an influenza A virus (H1N1) inhibition rate of 99.91%, and an avian influenza virus (H7N9) inhibition rate of 99.98%.

Feature 2: Non toxic and harmless:PuraWard's "silver+copper" ion mixing technology is not only non-toxic and harmless before use, but also has good physical properties. After use, the captured bacteria and viruses decompose into water, carbon dioxide, inorganic salts, and no toxic substances are produced. Therefore, it has passed the TCLP certification recognized by the American Environmental Protection Agency (EPA) issued by ASI.

Feature 3: SafetyPuraWard fiber has passed the OIT (octylisothiazolinone, N-octyl-4-isothiazolin-3-one) certification issued by Zhongke Testing due to its absence of toxic substances, non permeability, non desorption, non leaching, and no harmful substances. OIT is a potential risk to human health, so certification without OIT is a safe label.

Filter material obtained certification certificate:

1) Certificate of Severe Acute Respiratory Syndrome (SARS) coronavirus suppression rate of 99.58% issued by MICROBAC.

2) Certificate of 99.91% inhibition rate of influenza A virus (H1N1) issued by MICROBAC.

3) Certificate of 99.98% inhibition rate for avian influenza virus (H7N9) issued by MICROBAC.

4) TCLP certification recognized by the American Environmental Protection Agency (EPA) issued by ASI

5) Certification issued by Zhongke Testing without OIT (octylisothiazolinone, N-octyl-4-isothiazolin-3-one)

4、 Description of PuraWard's sterilization and antiviral technology characteristics:

By PuraWardAfter the sterilization and antiviral technology materials are made into non-woven fabric skeleton, they can be combined with electrostatic cotton and melt blown composite to become filter materials with filtersPuraWardAt the beginning, filters of various levels, including medium and high, can be widely used in air purifiers, fresh air systems, building central HVAC systems, and automotive air conditioning filters to circulate and purify indoor air or purify outdoor air, providing truly safe, healthy, and clean air.
