Lately I've been watching PC case content and ways of filtering to avoid dust... Up until the last minute I was sure this is a PC case kit 🤣 Would actually not be a bad idea..
I can't wait to have the time to design a laser cut computer case (that's what I thought this was at first). This is a pretty neat filter system! What I have in mind a quite a bit different style wise. I love laser cutting/engraving and I love computers! This is a nice looking kit! I might just work a filter like this into a negative pressure PC build, using a common filter like this a custom PC case is kind of a neat idea- perfect for a negative pressure case! (negative pressure generally just means more exhaust fans than intake fans)
A quick suggestion: Make one with 7x P12 or P12max instead of the 6x P14. The P14 is a decent allround pc case fan and not horrible as a radiator fan, especially for the money, but it doesn't have the static pressure you want for a filter application. They look good on paper, but that cfm number goes down the drain as soon as the airflow is impeded, to the point where they're easily overtaken by their smaller brothers. Even at the same noise levels. In a pc a 480x120 radiator with 4x P12 will outperform a 420x140 with 3x P14 by a good amount, even though the latter has more surface area. And a particle filter is even more restrictive than the fin array of a pc aio cooler.
Asking cause I don't know: Can you explain the static pressure in this circumstance? Specs on Arctic's website indicate that P14 has a static pressure of 2.40mm H2O and P12 has the static pressure of 2.20mm H2O. I looked at it this way when specing out a similar build. I wouldn't do the P12 max because it takes 2x the amount of power an equiv P14 will consume. However, I see that the static pressure of the P12 max is 2x that of the P14.
We make a 5-fan unit using the P12s, we avoid the P12max as we're trying to make a quiet machine that relies on multiple passes through a large filter area to give you the same performance as a loud commercial HEPA at full speed. We do use the P8 Max fan in our MINI version for travel.
It's a variation of a CorsiRosenthal Box using computer fans and 2 furnace filters resulting in a very quiet air purifier with superior performance compared to commercial HEPA.
No because it's a HEPA filter, you'll need an activated charcoal filter, those 6 fans would be enough for a 2x2 but keep the filter thickness in mind, as PC Fans do not create large amounts of pressure
I'm confused. A MERV 13 filter can catch 75% of air particles that are 0.3-1.0 micron in size. Increasing the air particle size range to 3-10 microns, a MERV 13 filter will catch 90%. Airborne viruses like COVID19 are approximately 0.1 micron. That said, wouldn't an airborne virus just pass right through that filter?
The virus is 0.1 micron but they travel through the air by attaching to a respiratory droplet that is 1 micron or larger. The idea is to use a large filter surface and multiple passes to achieve better performance than HEPA despite the greater single pass performance. Here is a good explanation: itsairborne.com/clean-air-delivery-rate-is-all-that-matters-5a5a064c211e
0.2 to 0.3 micrometer particles are the hardest to catch. Bigger OR SMALLER is easier to catch. Smaller particles are so light, they get punched around by air molecules, which makes them move through air in a zigzag pattern. The smaller they are, the more likely they are to hit the filter and stick to it. MERV 13 should filter about 50% of 0.1 ym particles. MERV 12 about 30. MERV 11 about 20. MERV 8 about 10%.
@@Violet-ui Everything I've read about virus particles in airborne form is they travel on aerosolized liquid particles expelled from person to person, these particles are 1 micron. Also, the performance of the filters in one pass is made up by the large filter surface of two 20 x 20 inch filters, cfm of the fans plus the multiple passes of the same air through the system.
PC fans are not good at creating high pressure. I reckon it would be way better to have a slightly bigger box that uses 4" filters instead of 1", to get a much bigger surface area and significantly higher airflow. You could also run the fans quieter and still get better performance. Also for literally just a couple bucks you could have a PWM controller to control the speed of these fans. Some people like it quieter, others prefer more airflow. But the choice of fans is great. The Arctic P12 are the best budget fan there is. Though at this point the P12 MAX is probably a better choice as it's only a little more expensive at 37 bucks for a 5-pack and is a little quieter while offering similar or even better performance and higher max fan speed.
We use the P8 Max for our MINI, very powerful but very loud. The Arctic P14 has good static pressure and runs very quietly. Our goal with this device was small footprint, low noise and good performance. There are always gains you can make performance wise by going the traditional CR Box route, big box fan and four filters, you can't beat it!
@@szeptaczsprezarek I have 6 of them But PC fans in general have little pressure, less than 2mmH2O. Probably because they're only 25mm thick. I am telling you, they would move so much more air if there were a 4" filter instead of 1". It would be absolutely worth it. It's not like those extra 3-6" make a big difference. It's already quite the large air filter

Though so too. Looked like a diy NAS or JBOD case. No idea why this was recommended to me

If you search for Nukit Tempest, you will see something similar to what you're describing.

I wonder what that thing is. Maybe there is a video to explain. . .

@@RobertFantinatto Thank you for your reply. I apologize for being a smarty pants. It's genetic.
