Such additional materials may be woven or non-woven materials. Examples of non-woven materials embody polypropylene, polyethylene, polyester, nylon, PET and PLA. Such a fabric could also be in the form of a non-woven sheet or pad. Suitable grades of non-woven polypropylene embody the well known grades generally used for surgical face masks and the like.
As a number of therapies could be simultaneously applied, no further water or power is required and the influence on the setting is lowered. The product is within the process of being licensed by bluesign and the Oeko-tex Eco Passports. Polygiene have tested the active ingredient towards Influenza A, BirdFlu, Norovirus and Corona over the years, and in all circumstances, have achieved over ninety nine% discount in the virus. The effectiveness of the mask towards the coronavirus and Influenza has been tested by an independent laboratory and a number one UK college.
Superior Viraloff® Antiviral Know-how
Alternatively the substrate may be within the form of an open-cell foam, e.g. a polyurethane foam as can also be used for air filters, for example in nasal air plugs. The filter material described herein could also be made in varied methods, during which the air- permeable substrate is combined with the acidic polymer. Other suitable acidic polymers are believed to incorporate polyvinyl phosphonic acids. Acidic polymers which have been found helpful for the purposes herein have been discovered to have molecular weights within the range 30,000 to 2,000,000 but molecular weight doesn’t seem like important, and this may be simply an exemplary vary.
The vesicle expertise depletes the viral membrane thus silver can work more effectively and rapidly to attack the core of the virus. And there may be all the time the chance of contracting the virus through touching the face after touching the contaminated surface of the masks or other surfaces contaminated by the mask. The test mask is mounted and sealed inside a take a look at chamber. A nebulizer delivers an aerosol of the target virus inoculum to the upstream aspect of the masks. A collection dish placed under the masks downstream collects aerosol droplets that cross via the masks sample. The discount in infectivity with and without mask is calculated as an indicator of effectiveness.
It is believed that the filter material of this invention could also be effective on this method against the virus that trigger colds, influenza, SARS, RSV, bird flu and mutated serotypes of these. A suitable materials for this additional materials is polyester, cellulose or non-woven polypropylene of the type conventionally used for surgical masks and the like. A layer of the filter materials and a layer of the further materials might for instance be welded collectively, e.g. round their respective edges, e.g. by ultrasonic welding. A masks according to declare 23 whereby the entire loading of the acidic polymer plus any carboxylic acid if any and plus any surfactant if any on the substrate of the filter material is within the vary g/m2. A masks based on any one of many previous claims whereby the total loading of the acidic polymer plus any carboxylic acid if any and plus any surfactant if any on the substrate of the filter material is within the range g/m2.
- 7 A masks in accordance with declare 6 wherein the acidic polymer contains a polymer of acrylic acid or methacrylic acid.
- Further experiments were performed using a polyester substrate material.
- The antiviral technology is protection of the treated product, not the wearer.
- P2F had now overcome the delay in testing, reported on eight October, by conducting live virus exams at two independent UK laboratories.
This loaded material was moulded into mask shells in a conventional manner identified within the artwork. Further experiments were carried out utilizing the “6% solids” loading answer referred to above, utilized by spraying or immersion to lighter polyester supplies. Such filter materials may have unbiased utility, e.g. in other kinds of air filter system. Therefore in a further side the present invention offers a filter material appropriate to be used within the face mask of this invention. Preferred sorts, features and embodiments of such a filter material are as mentioned above. Certain filter materials disclosed herein for use in the face mask of this invention are believed to be novel per se.
Wise Protec products are engineered to self sterilise in less than 24 hours. HeiQ Viroblock’s speedy mode of motion makes this expertise one-of-a-type to destroy dangerous enveloped viruses. Treated face masks show significantly improved discount in virus infectivity compared to untreated control masks.
This invention relates to a novel system being an oral and/or nasal air filter in a position to remove and neutralise dangerous virus from inhaled air contaminated with such virus, and from contaminated air exhaled from sufferers infected with such virus. In particular the invention relates to such a tool within the type of a face mask. The invention also relates to novel filter supplies suitable to be used in such a device. The antiviral technology is protection of the handled product, not the wearer. Whether this is additionally useful for the consumer is dependent upon many other factors.
Virus Protection For You And Your Loved Ones
The coating transforms the bottom material into an anti-viral, multi-useful protecting snood. So gentle and breathable you won’t imagine its virus stopping power. Proven to lure and kill airborne enveloped influenza viruses. A filter material according to claim 28 whereby the acidic polymer is predicated on maleic acid moieties which include -[-CH.
