It’s important to note that while carbon filters are highly effective in reducing chemicals and odors from the air, they are not extremely effective when it comes to addressing particulate matter and allergens. This is because activated carbon filters can absorb the chemicals in common household construction and cleaning materials.
Children, the elderly, and asthma sufferers have a lot to to gain from this type of filter.
And once a pollutant is absorbed, it will never be released.Īctivated carbon is particularly useful for those who are extremely sensitive to poor air quality. It can capture a wide rang of pollutants, from chemicals to gases, smoke, and odors. Today’s activated carbon filters rely on minuscule doors that are extremely absorbent and can quickly bond with particulate matter chemically.
Then, it became even more popular during World War I when researchers found it could protect soldiers when used in gas masks. It was sold to clean water and take coloring out of sugar-based products. Once “activated” carbon becomes porous and is able to absorb large amounts of pollution.Īctivated carbon first became popular in the early twentieth century. Activated carbon takes that same building block and improves it. From our bodies to the food we eat, every living thing has carbon in it. Eventually, these particles will become lose and reenter the air.Ĭarbon is the building block of everything in our world. Instead, they move the particles from the air to solid objects such as walls - leaving them for you to be exposed to. This is because ionizers are not able to absorb or eliminate harmful particles. Rather than cleaning the air, they often mask smells and visible particulate matter. Time and time again, ionizers have proven to be ineffective. While this may sound like an amazing, natural solution, it can be far from it. Once the ion is weighed down by the particulate matter, it’s meant to get stuck to the ground or wall. Because of their charge, these oxygen particles can attack pollen and dust like a magnet. Negative ions are nothing more than negatively charged oxygen atoms. If you’ve ever shocked yourself after walking around on carpet in socks, ions are to blame. Ions are naturally occurring particles that have either positive or negative charges. Ionizers, also known as negative ion air purifiers, rely on chemical injection to purify the air. If you’ve settled on the HEPA approach, be sure to look at a multi-faceted filter design! As a result, most incorporate activated carbon materials to address those downsides. It’s important to note that HEPA filters will not remove odors, chemicals, or gases. Larger particles will go through impaction, where they collide with the fibers and become stuck within them. Secondly, slightly larger particles will stick to the fibers upon contact - otherwise known as interception. The smallest particles experience what is known as diffusion, which is when particulate matter becomes trapped by gas particles and the fibers. In more detail, HEPA filters rely on three approaches to prevent particulate matter from passing through. You should expect to replace the filter every two to three years. The particles remain trapped in the filter, however, meaning it decreases in effectiveness over time. These flaps trap particles as air is pushed through by a fan. Extremely thin pieces of fibrous material are folded to create flaps. You can imagine a HEPA filter as an accordion. Better yet, it does all of that without relying on harsh chemicals or dangerous byproducts! They’ll filter out bacteria, chemicals, and viruses to create a more sanitary living environment. And because the human eye can only see things larger than 10 microns, that means HEPA filters catch what you can’t see. HEPA filters got extremely popular due to their use in medical settings, and trap around 99.97% of particulate matter larger than 0.3 microns. High Efficiency Particulate Air Purifiers were developed back in the 1940s.
