Face masks are increasingly being worn to protect from airborne pathogens and pollution. These work by filtering the ambient air when the wearer breathes in, typically removing around 95% of moisture droplets and particles greater than 5 microns (millionths of a meter) in diameter. Coronaviruses, such as Covid-19, are as small as 0.3 microns, and can only be stopped from entering the wearer's nasal and oral system when attached to a larger particle. Fortunately, this is generally the case when the moisture droplets are generated by an infected person.Oxford Dynamics, an Oxfordshire based start-up, is developing a wearable, personal air purification unit, known as “Air2”. The USB rechargeable design aims to offer superior protection against airborne particulates and pathogens, as well as the ability to neutralize gases associated with pollution in dense urban environments such as NOx, SOx and PAHs. Air2 exists at a concept stage with a number of key elements currently undergoing design and prototyping. Funding for this project will help accelerate the development of the product towards commercial release.Overseas interest from India, home to 22 of the world's 30 most polluted cities, has been expressed and nascent talks are underway, supported by the UK's Department for International Trade (DIT).All product development and product accreditation with take place in the UK, with manufacturing expected to take place both in the UK and India.EXTENTION FOR IMPACTThe Extension for Impact grant will enable the production of a higher quality, higher TRL pre-production prototype that can be used as an asset for marketing and promotional activity. Current 3D printed plastic materials will be replaced by brushed aluminum for the Air Processing Unit (APU) body, for example. The pre-production unit would also be used to complement the activity of Oxford Dynamics in India. The Extension for Impact grant would also permit the pre-production unit to undergo formal EMC compliance testing (in the UK) to ensure compliance to the appropriate electrical safety and emissions standards in order to obtain the required CE Mark.

人们越来越多地戴口罩，以防止空气传播的病原体和污染。当佩戴者吸气时，这些过滤器通过过滤环境空气来工作，通常可以去除大约95%的直径大于5微米（百万分之一米）的水分液滴和颗粒。冠状病毒，如新冠肺炎，小至0.3微米，只有附着在更大的颗粒上才能阻止其进入佩戴者的鼻腔和口腔系统。幸运的是，通常情况下，这种湿滴是由感染者产生的。牛津郡的初创企业牛津动力公司正在开发一种可穿戴的个人空气净化装置，称为“空气2”。USB可充电设计旨在提供对空气中颗粒物和病原体的上级保护，以及中和密集城市环境中与污染相关的气体（如NOx、SOx和PAH）的能力。Air2目前处于概念阶段，许多关键元素正在设计和原型制作中。对该项目的资助将有助于加速该产品的商业化开发。印度是全球30个污染最严重的城市中的22个城市，印度已经表达了海外兴趣，并在英国国际贸易部（DIT）的支持下进行了初步谈判。所有产品开发和产品认证都在英国进行，与制造预计将在英国和印度进行。扩展的影响扩展的影响赠款将使生产更高质量，更高的TRL预生产原型，可用作资产的营销和促销活动。例如，目前的3D打印塑料材料将被用于空气处理单元（APU）主体的拉丝铝所取代。前期制作单位还将用于补充牛津动力公司在印度的活动。影响力扩展补助金还将允许预生产单元进行正式的EMC合规性测试（在英国），以确保符合适当的电气安全和排放标准，以获得所需的CE标志。
