ASUS Antibacterial Guard is tested by an independent third-party laboratory according to the ISO 22196 standard (Measurement of antibacterial activity on plastics and other non-porous surfaces).
KUALA LUMPUR, Malaysia, June 23, 2022 — ASUS today announced that ASUS Antibacterial Guard antibacterial protection is now protecting the widest ever range of ASUS laptops. Availability includes the majority of Vivobook models and a number of commercial laptops, including the Expertbook B3 Flip (B3402), ASUS BR1100C and BR1100F as well as the ASUS Chromebook CR1 and Flip CR1 education laptops. This feature will be extended to cover more models in ASUS’ lineup, including the Zenbook models, with more than 8 out of 10 ASUS laptops sold protected by Antibacterial Guard.
According to a recent global survey of over 20,000 laptop users conducted by Pollfish and ASUS in March and April, 20221, laptop users are increasingly concerned with the hygiene of their work environment, especially in locations where a few coworkers work face-to-face. In the survey, 88% of prospective laptop purchasers expressed a positive interest in learning about antibacterial laptops, and 68% are interested in purchasing one.
For peace of mind when using a laptop under such circumstances, ASUS Antibacterial Guard works efficiently to inhibit the growth of potentially dangerous bacteria. This state-of-the-art hygiene technology has been clinically tested using protocols defined in the ISO 22196 international standard, and has been shown to have a bacterial-inhibiting effect exceeding 99% over a 24-hour period2. This silver-ion surfacetreatment3 keeps the bugs at bay, ensuring the laptop is clean and sanitary for more than 3 years in normal usage, and reducing the spread of potentially harmful bacteria via contact.
ISO 22196-tested
To ensure the effectiveness of the treatment, independent labs tested Antibacterial Guard according to the strict ISO 22196 standard test protocol. This is a method designed to quantitatively test the ability of plastics and non-porous surfaces to inhibit the growth of bacteria over a 24-hour period of contact. The test uses bacterial cultures that include Escherichia coli (E. coli) and Staphylococcus aureus, which are widely used as industry test targets. The results showed that this special treatment successfully reduced the number of bacteria by more than 99% over the duration of the test.
ASUS Antibacterial Guard is a surface coating on the laptop, mainly containing positively-charged silver ions. Upon contact, the silver ions and negatively-charged microbial cells are attracted to each other, causing the ions to pierce through the surfaces of bacterial cells and damage their structure, impairing their ability to develop and spawn.
Targeted protection
ASUS Antibacterial Guard is applied to the most frequently touched surfaces of the laptop — such as the keyboard, the touchpad (or ASUS NumberPad), the palm-rest area, and the combined power button and fingerprint sensor. Users can identify an ASUS Antibacterial Guard-protected laptop by checking for the Antibacterial Guard sticker6 attached to the palm-rest area of the laptop. During 2022, ASUS Antibacterial Guard will be available across near full range of Vivobook clamshell and convertible laptops, and protection will also be expanded to include selected Zenbook models.
Long-lasting protection
In the user survey, 20% of respondents who were doubtful of the effectiveness of antibacterial laptops expressed a fear that the antibacterial coating could wear off easily. According to our durability tests, the ASUS Antibacterial Guard treatment can be expected to last for at least three years in normal usage7.
Household cleaning products and agents such as alcohol wipes and soap water won’t easily wear away the surface treatment, ensuring ASUS Antibacterial Guard’s long-lasting bacterial-inhibiting effect.
