| Building (And Testing) A DIY Air Purifier - Hackaday Posted: 29 Jan 2020 12:00 AM PST Whether it's the usual pollution of the city, or the fact that your corner of the globe happens to be on fire currently, poor air quality is a part of daily life for many people. One way of combating this issue is with a high quality HEPA filter in your home, but unfortunately that's not something that everyone can afford to even has access to. Which is why [Adam Kelly] decided to design this DIY HEPA air purifier that can be built for less than $100. That might still sound like a lot of money, but compared to the $500 sticker price he was seeing for the models recommended by health officials, it's certainly a step in the right direction. Of course, it's only a deal if it actually works, so a big part of the project has also been verifying the design's ability to filter particles out of the air in a timely manner.
In terms of testing, [Adam] wasn't worried about the purifier's ability to actually filter out smoke particles; unless the manufacturer lied about the capabilities of the filter itself, that part is a given. But he was curious about how effective the fan would be in terms of circulating air through a room. By installing a pitot tube from one of his drones into the lid of the purifier, he determined the airflow in the center of the filter to be approximately 160 CFM. By his calculations, that means it should be able to circulate all the air in his 25 cubic meter office around 10 times per hour. That's a promising start, but [Adam] says he'd still be interested in a more detailed analysis of the design's performance by anyone who might have the equipment to do so. As he lives in Australia, this project is more than just a passing fancy for [Adam]. He only has to look out the window to see that the air he's breathing is filled with smoke from the raging bushfires. They say that necessity is the mother of invention, and breathable air is pretty high up on the list of human necessities. Our hat's off to anyone who sees their fellow citizens suffering and tries to use their skills to come up with a solution.  |
| Coway Airmega Smart Air Purifier Review: Amazon fav gets smart update [Video] - 9to5Toys Posted: 17 Feb 2020 02:45 PM PST Air purifiers are a great way to help control air quality in homes and other tight spaces. Coway's Airmega AP-1512HH has been an editorial top pick on Amazon for a while with over 1,600 reviews and 4.5 stars, but they've improved upon it even more by adding Wi-Fi connectivity and smartphone control with the $299 Airmega Smart Air Purifier. Head below to see it in action and check out the new functionality. Coway has had a lot of success with the older Airmega AP-1512HH. This latest version takes that same popular product and adds Wi-Fi connectivity for even more convenient control. With the Coway Airmega Smart Air Purifier, you can control the air purifier directly on the unit or from a smartphone. This makes it easy to see when the air quality might be poor and when filters need to be cleaned or replaced. Three Filter systemThree filters help the Airmega smart purifier to clean up the air. On the front, there is a washable pre-filter to catch larger particles, an activated charcoal filter, and a true HEPA filter. The pre-filter needs to be cleaned every 3-weeks and the Max2 HEPA filter replaced every year. Cleaning and replacing the filters is very easy. Just pop off the plastic cover and use the pull tabs to remove the filters. Coway Airmega Smart Air Purifier: Video
Making it smartOf course, a major update to this purifier is the addition of control via a mobile app. Inside the IoCare app, the home screen gives a status report on the current air quality, outside air quality based on location, and current states of the air purifier. A nice addition is the filter lifecycle status. Because of the normal cleaning and replacement cycles, the app can give you a percentage of the remaining lifecycle and let you know when cleaning or replacement is required.
In the air quality report section, the app gives a point graph on the measured air quality. Points are placed in a 3-tiered system to indicate if the air quality is good, unhealthy or very unhealthy. My only wish here was that it gave a little more detail on what is causing the air quality to change to unhealthy. Is the Co2 level above the recommended numbers? Or are there too many pollen particles? It would be very interesting to have data on what is changing air quality. Another benefit of the app is complete control over the AP-1512HHS air purifier. You can turn it on, off, change fan speeds and even set a schedule for when the air purifier will run. So if you're running it in your office, you can set a schedule that will run only when you are in the space and save some filter duration.
Does it stand out?I had the AP-1512HHS set to auto fan most of the time. When it's on the lowest fan setting, for the best air quality, it is extremely quiet. When the light turns purple and the air is deemed unhealthy, the fan will kick up to the next level and it becomes much more audible. Put it on the highest setting, and it starts to sound like a box fan on the highest speed – it gets pretty loud. But, in most of my testing, the air quality was deemed good so the fan stayed in the lowest and quietest setting. Check out the video to hear how it sounds at the different fan speeds.
Wrapping upOverall, the Airmega AP-1512HHS is an extremely easy to use air purifier. It received high marks before, and the addition of Wi-Fi connectivity and control makes it even better. It'd be nice to have a little more detail on air quality and what is happening when the AP-1512HHS senses unhealthy air, but the auto fan function is great when it speeds up to take care of it.

| Can Air Purifiers Protect us From the Coronavirus? - The Beijinger Posted: 14 Feb 2020 09:00 PM PST Most of us understand how fans work, but how about the filter? The filter – typically a HEPA filter – is the workhorse of any purifier. Turns out they're nothing fancy either. They were invented back in the 1940s, and they're just a mat of synthetic fibers, which can capture over 99 percent of tiny air pollution particles. COVID-19 is a new respiratory virus first identified in Wuhan in China's Hubei Province. Scientists have already taken electron microscope images to measure the size of COVID-19 "virions" (or particles). The virions are spherical particles with diameters of approximately 125nm (0.125 microns). The smallest particles are 0.06 microns, and the largest are 0.14 microns. That makes the COVID-19 particles smaller than PM2.5 particles, but bigger than some dust particles and gases.
Can HEPA filters capture particles as small as the COVID-19?If we look to the definition of HEPA filters on Wikipedia, it says HEPA filters must remove: "99.97 percent of particles that have a size greater than or equal to 0.3 µm." It only mentions particles 0.3 microns and above. So what about smaller particles the same size as the COVID-19? Can HEPA filters capture these? This exact question has led to years of confusion and false advertising claims about HEPA filters, and this confusion is now leading to more misinformation during the spread of information during the COVID-19 outbreak, so let's get to the bottom of it. Researchers at the University of Minnesota tested this question with weaker fiberglass furnace filters and higher-grade HEPA filters. In their test, they shot particles of silver from 3 to 20 nanometers at the filters (that's between 3 to 20 times smaller than COVID-19 particles). If a particle is smaller than the holes in the net, it gets through. Makes sense! However, it turns out that particles as small as the COVID-19, and other nano-particles get captured using a scientific phenomenon called diffusion. READ: Learn more about the science behind diffusion and how it captures nano-particles Diffusion is surprisingly effective at capturing tiny virus-sized particles. According to NASA, HEPA filters capture "virtually 100 percent of particulates."
The results showed that filters captured 99.99 percent of particles smaller than 5 nanometers. Bingo! HEPA filters (and even lower-grade filters like furnace filters) are incredibly effective at capturing smaller sized particles such as the COVID-19. So what does this mean for COVID-19?If you're living in a common house, or you're working in an office or school with a large number of employees, turning on your air purifier can help filter out any virus-sized particles in the air, potentially reducing the chance of transmission. HEPA filters, in one pass, can be expected to filter out over 99 percent of the COVID-19. Bottom Line: Can air purifiers capture COVID-19?Air purifiers that contain HEPA filters or even lower grade filters can capture virtually all sizes of solid particles, including particles 0.1 microns in diameter – or the same size as the COVID-19. If you're living in a shared house, or are working in a closed environment with lots of people, turning on an air purifier could help reduce the spread of COVID-19. For those in places with central air (HVAC) system, make sure the systems contain filters and are well maintained. If your HVAC contains no filters, installing air purifiers in each room could still help reduce the spread of viruses. Perhaps another more important reason to turn on your purifier right now is because Beijing and much of Dongbei's air pollution levels are over 20 times the WHO safe level. Beijing's government announced on Tuesday a yellow pollution alert due to the high levels of PM2.5 in the city. Turn on your air purifier, and limit your time outside!  |
