What is CASA-V - Introduction to 5A Functions

CASA-V is the first in Hong Kong to have the 5A functions of air purification, anti-bacteria, anti-odor, anti-mildew and anti-mite. Whether it is bed sheets, quilt cores, pillows, or even baby bedding, it can help you and your family to protect against bacteria and resist viral and bacterial invasion! But do you know the principle of 5A function?

CASA-V uses Japanese research and development technology and high-tech materials, which will produce a "photocatalytic" reaction under the action of light or friction! When organic pollutants and bacteria in the air come into contact with the surface of bedding, they are immediately oxidized, decomposed and killed, thus inhibiting bacterial growth and creating a sterile sleeping environment.

Browse the following details to learn more about 5A features.

First, share the correct knowledge about dust mites:

• Dust mites feed on dandruff, a product of human metabolism.
• The amount of dust sucked out by the dust mite machine is not equal to the amount of dust mites removed.
• The principle of the dust mite machine is to suck out human dandruff and dust, which helps reduce the food source of dust mites.
• Dust mites are 0.1 to 0.3 mm in size, while a strand of hair is approximately 0.08 to 0.1 mm in diameter.
• If dust mites are placed in a test tube, they can indeed be seen with the naked eye, but once they are integrated into bed sheets, pillows, stuffed animals, etc., they are relatively difficult to detect.
• Dust mite excrement is a major cause of skin allergies.
• Dust mite corpses may also cause allergies.

The anti-dust mite principle of CASA-V is to create an environment that is unfavorable and difficult for dust mites to survive by triggering a "photocatalytic" reaction with light, thereby reducing the survival rate of dust mites from the root.

CASA-V fabric has been proven to be anti-mite by the Tokyo Women's Medical University Laboratory and national testing!

A report from the Tokyo Women's Medical University Laboratory shows that after five days of exposure to light, the number of dust mites can be reduced from 90 before the test to 0*!

National testing has confirmed that the dust mite repellent exceeds 70% in 24 hours**!

The high-tech materials used in CASA-V have been proven to be antibacterial under the action of light or friction!

1. When organic pollutants and bacteria in the air come into contact with the surface of bedding, they are oxidized, decomposed and killed!
2. Create an environment that is unfavorable for the growth and survival of bacteria, inhibiting the growth of many types of bacteria!
3. Convert harmful substances into pollution-free [H2O] and [CO2], creating a sterile sleeping environment for users!

CASA-V material has been specially certified by the Japan Chemical Fiber Inspection Association, proving that it can greatly reduce the number of live bacteria such as Escherichia coli, Klebsiella pneumoniae, Staphylococcus aureus, and Pseudomonas aeruginosa!

According to the E. coli test report, compared with ordinary cotton cloth and after 8 hours, CASA-V can reduce the number of live E. coli bacteria by 70%*!

*Test method: Based on JIS R 1702:2012 Glass bonding method

The CASA-V material has been tested by the Japan Chemical Fiber Inspection Association and has been shown to be able to effectively decompose irritating odors such as ammonia and methyl mercaptan gas!

Taking the ammonia test as an example, compared with ordinary cotton cloth, after being exposed to ultraviolet rays and placed for 24 hours, CASA-V fabric can reduce the ammonia concentration by up to 99%, thereby achieving the function of deodorization and air purification!

CASA-V fabric has been tested by the Japan Chemical Fibers Association* and the National Testing Center**, and is mildew-proof!

According to the test report of the National Testing Center, Aspergillus niger, Trichoderma viride, Penicillium funiculum and Aspergillus sphaeroides were used as the test strains**, and the result showed that the anti-mildew grade reached the highest level! The result confirmed under a magnifying glass was "no obvious mold growth"!

*Tested according to JIS R 17052008
**The test method is GB/T 24346-2009 Petri dish method

CASA-V material has been tested by the Japan Chemical Fiber Inspection Association and can effectively decompose irritating odors such as ammonia and methyl mercaptan gas!

In particular, the methyl mercaptan test showed that compared with ordinary cotton cloth, after being placed for 24 hours, CASA-V fabric can reduce the concentration of methyl mercaptan by up to 93%*, thereby achieving the function of deodorization and air purification!
