# Frugal Air Filters This Pollution Air Filter Gets Rid of 99% of Harmful Pollution Particles By Rahul Kalvapalle | Published 2015-02-27 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/pollution-air-filter References: [gizmag](http://www.gizmag.com/low-cost-air-pollution-filter/36288/) & [news.stanford.edu](http://news.stanford.edu/news/2015/february/filter-air-pollution-021815.html) Scientists at [Stanford University](https://www.trendhunter.com/trends/stareep) have developed a ridiculously effective yet impressively inexpensive pollution air filter. This semitransparent filter is capable of filtering out 99% of what are known as 'PM2.5 particles', which are considered to be the particles most harmful to the human respiratory tract. These filters could be used to create better [protective facemasks](https://www.trendhunter.com/trends/pureaura), window screens and industrial filtration systems and could even help reduce pollution from cars and smoke stacks. Incredibly, these air filters don't require any power to function making them energy-efficient as well. With pollution a huge problem worldwide but particularly in booming developing markets like China and India, this inexpensive pollution air filter solution could prove to be a huge boon. ## Trend Insights (Trend Hunter) - Score: 2.2/10 - Popularity: 26% | Activity: 33% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial, Gen X - Top markets: North America, Europe, Asia ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Tech](https://www.trendhunter.com/tech) > [Gadgets](https://www.trendhunter.com/gadgets) ## Key Themes ### What's Driving This Trend - **Inexpensive Pollution Air Filters:** The development of inexpensive pollution air filters opens up opportunities to create more affordable and accessible protective facemasks, window screens, and industrial filtration systems. - **99% Particle Filtering:** The ability of pollution air filters to filter out 99% of harmful PM2.5 particles presents opportunities for improving air quality and reducing pollution from cars and smoke stacks. - **Power-less Air Filters:** The energy-efficiency of air filters that don't require any power to function can lead to sustainable and cost-effective air filtration solutions. ### Who This Affects Most - **Healthcare:** The healthcare industry can capitalize on inexpensive pollution air filters by integrating them into protective facemasks for improved respiratory protection against harmful particles. - **Manufacturing:** The manufacturing industry can explore the use of inexpensive pollution air filters for industrial filtration systems, enhancing workplace air quality and reducing harmful emissions. - **Environmental Technology:** The environmental technology industry can leverage power-less air filters to develop sustainable solutions for reducing pollution and improving air quality in urban areas. ## Related on Trend Hunter - [High-Efficiency Air Purifiers](https://www.trendhunter.com/trends/highefficiency-air-purifiers.md) - [Cutting-Edge Air Purifiers](https://www.trendhunter.com/trends/xiaomi-4.md) - [Hospital-Grade HEPA Air Cleaners](https://www.trendhunter.com/trends/hepa-air-cleaner.md) - [Compact Air Purifiers](https://www.trendhunter.com/trends/airmega-50.md) - [Intelligent Low-Maintenance Air Purifiers](https://www.trendhunter.com/trends/xiaomi-smart-air-purifier-4.md) - [Compact Cylindrical Air Purifiers](https://www.trendhunter.com/trends/coway-airmega-100.md) - [Advanced Antiviral Air Purifiers](https://www.trendhunter.com/trends/antiviral-air-purifier.md) - [Water-Powered Air Purifiers](https://www.trendhunter.com/trends/airsancta.md) - [Circular Minimalist Air Purifiers](https://www.trendhunter.com/trends/iqair-atem-x.md)
