Show All ItemsHi y’all, I'm Ian van Mourik a Product Designer from the Netherlands. This instructable is a brain child that I just had to share with the world. Bad air quality causes various health problems and purification solutions are often complex and expensive. The solution is an open source no nonsense air purifier: the OPEN AIR!This instructable is based on my first experimental prototype of the OPEN AIR. It’s meant to be a platform to build upon and improve. My personal goal is to test and improve the design and effectiveness. Collectively we can provide new and better solutions. The modular filter design makes it possible to change and test different kind of filters. This Design is based on a carbon type filter in collaboration with two pressure optimized 120mm 12v PC fans. It´s controlled by an Arduino with a gas sensor and a LED panel for subtle visual feedback. If you decide to build your own OPEN SOURCE AIR PURIFIER, be ready to roll up your sleeves, because this won't be an easy one.

It will include laser cutting, 3D printing, prototyping, soldering, programming and a lot of other bits and bobs. It will be an advanced instructable. But don't let it scare you, because the reward is big, very big! Like thousands cubic meters of fresh pure clean air big.

, beginning with the laser cut wooden frame. I unfortunately do not own a laser cutter :(. But lucky there is a FABLAB nearby: #stadslabrotterdam.I used 3mm triplex birch wood sheets, birch wood is ideal for laser cutting because it is very soft, and it's cheap witch is always good. Speed and power settings for the laser cutter are depended on the type of wood and machine you are using. Ask the FABLAB crew for help if you are not sure.You will need one top and one bottom piece, 22 regular ribs, 1 wooden rib with the cutouts for the gas sensor, 1 Plexiglas rib for the LED and a couple of assembly tools. For the LED rib I used 3mm clear blue Plexiglas which I roughly sanding in a vertical direction. Roughing up clear Plexiglas diffuses the light causing it to light up. Feel free to experiment! After cutting check everything with a quick test fit, NO GLUE! I would highly recommend cover the wood with some kind of varnish or paint to prevent the wood from warping over time. So sand it down and do whatever you desire.

I used heavy duty varnish for a old and kind of dirty finish.« Bring NASA Technology Home. Born In The Imaginings Of NASA Scientists. The Airocide Story begins in space. Planning for a manned mission to Mars, the question arose as to how to feed the crew when there’s no way to resupply them. window air conditioner coil cleaningGrow gardens in space.good air purifier for apartment But There’s A Catch.air purifier ratings canada Nearly all plants, especially those that produce fruits and vegetables emit ethylene gas. Ethylene, a typical volatile organic compound (VOC), is the natural occurring plant hormone that signals fruits and vegetables to ripen. On earth ethylene naturally dissipates into the atmosphere.

But, in a sealed spacecraft like the shuttle or space station, concentrated exposure causes fruits and vegetables to ripen too rapidly and spoil before they can be consumed. In short, NASA had a VOC problem. SolutionBringing NASA Technology Down To Earth. Technology Takes Off Across Commercial Industries. Since 1998 the commercial uses for the technology have rapidly expanded. Food packers, wineries and grocery chains have been using Airocide to protect their products from mold, bacteria and to extend the shelf life of perishables by as much as two weeks. Hospitals, clinics, emergency rooms, dental offices, schools and daycare centers have been using Airocide since 2003 to curtail the spread of infectious airborne disease.Air Purification That Works. For the first time this NASA developed technology is available for your home. An air purifier so scientifically advanced it doesn’t use filters. So radically different, it looks and works like no other air purifier before it.

That's right, the world is running short on air pollution, and if we continue to cut back on smoke pouring forth from industrial smokestacks, the increase in global warming could be profound.Cleaner air, one of the signature achievements of the U.S. environmental movement, is certainly worth celebrating. Scientists estimate that the U.S. Clean Air Act has cut a major air pollutant called sulfate aerosols, for example, by 30% to 50% since the 1980s, helping greatly reduce cases of asthma and other respiratory problems.But even as industrialized and developing nations alike steadily reduce aerosol pollution -- caused primarily by burning coal -- climate scientists are beginning to understand just how much these tiny particles have helped keep the planet cool.

A silent benefit of sulfates, in fact, is that they've been helpfully blocking sunlight from striking the Earth for many decades, by brightening clouds and expanding their coverage. Emerging science suggests that their underappreciated impact has been incredible.Researchers believe greenhouse gases such as CO2 have committed the Earth to an eventual warming of roughly 4 degrees Fahrenheit, a quarter of which the planet has already experienced. Thanks to cooling by aerosols starting in the 1940s, however, the planet has only felt a portion of that greenhouse warming. In the 1980s, sulfate pollution dropped as Western nations enhanced pollution controls, and as a result, global warming accelerated.There's hot debate over the size of what amounts to a cooling mask, but there's no question that it will diminish as industries continue to clean traditional pollutants from their smokestacks. Unlike CO2, which persists in the atmosphere for centuries, aerosols last for a week at most in the air.

So cutting them would probably accelerate global warming rapidly.In a recent paper in the journal Climate Dynamics, modelers forecast what would happen if nations instituted all existing pollution controls on industrial sources and vehicles by 2030. They found the current rate of warming -- roughly 0.4 degrees Fahrenheit per decade -- doubled worldwide, and nearly tripled in North America.Despite intransigence on carbon emissions, even China is taking aggressive steps to cut sulfate pollution, and temperatures have risen as a result. But surely the answer can't be to slow our drive to clean our air. One way to buy time might be to tackle another air pollutant that warms the planet: soot. In 2008, scientists estimated that so-called black carbon, soot's prime component, is responsible for 60% more global warming above that caused by greenhouse gases. Cleaner-burning diesel engines in the West and more efficient cookstoves in the developing world are the answer. But on both scores, "relatively little has been done to address the problem," says the Boston-based Clean Air Task Force.In the face of severe climate risks, credible scientists are beginning to study geo-engineering -- tinkering with global systems to reduce warming directly.
