Ultra high CFM quiet VOC eater!

On max: 53db, 75w, 710cfm! CADR?

ugly/huge, I know my tweeps can appreciate it. Here’s the specs, from the bottom up:

-AC Infinity 10” carbon filter
-Filter box with MERV11
-710 CFM Hyperfan stealth 8” fan
-AC Infinity Duct Silencer
-6” output It’s all leftover pro grow gear n so this would be stupidly expensive for home use, but I had this stuff so here it is. It has a digital controlled electronically commutated motor, high cfm/pressure with lowest noise possible. Great under pressure, CADR should be high % of 710cfm

MASSAGE during Covid:

For my disability there comes a time when only skilled therapeutic neuromuscular massage can help me, and my doc recommends it. Here’s how I’ve done it, many times since 2020, without catching anything:🧵 1. I pay extra to do it at home. So I can control ventilation.

2. Therapist I’ve known for years, vaxed and fully boosted, claims he’s never had it. I trust him generally

3. He came w surgical, I gave him a fresh KN95 and molded out the pointy tip for him. He wore it no issue

The Warp Core Family

L-R:
Warp Core, 46db 100 cfm CADR est
Warp Core Maxx, 46db 200 cfm
Maxx Core, 40db 70 cfm
Micro Core, 37db 30 cfm

Micro/Maxx Core breakdowns in thread #daifu Here’s the Micro Core. Fan, filter, usb fan adapter, usb plug. Legs are random bits I had, and optional.

Micro Core Build!

The cheapest and easiest build I’ve got. Based on my new go-to Trusens Odor / VOC filter with HEPA n lots of carbon, this time in Small. It’s $37 now, usually 49. Fan is $15.

$56 all in for 50-100 cfm CADR HEPA and VOC

USB powered plug and play no effort! It’s a great filter. It’s open on both sides, so find a flat surface to put it down onto upside down, then drop any 140mm fan on top. The filter comes w foam surrounds that make a seal w table and fan. Plug into USB (or 120) and voila! I am going to be sharing a few versions.

The Warp Core Fandelier Maxx Build Thread is here!

Just cleaned it, upgraded the filter and took pics the whole way. So follow along here if you want to know how to build a ~200+ CADR HEPA and VOC filter that’s quiet, powerful, effective, unique and special looking to boot. Here’s the parts list and an Amazon shopping list you can use to find everything.

Grandpa is visiting frm CAN for Tday. Here’s what we did:

1. He started masking a few days before coming. He doesn’t usually. He is vaxed prev n got over covid a month ago.

2. Made him promise to mask on plane.

3. Tested for 3 days, masked when he was in the house.
🧵 4. We have a guest room w separate entrance/air. When he was in shared space, windows/doors open, AC fan on (Merv13), range hood on low, bathroom fans on n distanced. PC fan CRBs in each room

5. 4th day we stopped masking. No one had symptoms. Now he masks like we do in stores

Just found a great study for Covid and BUSES, & it has a simple solution! They use the windshield defroster on blast as fresh intake, n crack half of the other windows, got ACH 22!!

Won’t address diesel particulate just COVID

Ofc since most buses are diesel, this will result in more particulate in the bus, not ideal. However, the acute risk of COVID is worse than acute PM2.5 exposure if you have to choose!

This easy ventilation technique plus onboard filters like the Warp Core would be ideal

Deets:

Ok here’s an early look at the School Bus #warpcore in tabletop position. Whole thing screws together by hand, no wiring just plug n play. Fans are combined 260cfm, cadr is close maybe ~220. Fans are black, or static blue or red, so I went ez w leds. 12v only. 45db@1m more coming

https://twitter.com/CRBoxKits/status/1711908884628308348

It’s twice as big volume wise as the 120mm fan white fandelier. Sound is the same, but CADR is more than double. With all the carbon options this filter has, it will be able to clear COVID, diesel particulate and VOCs/fumes as well, just gotta choose the right filter. Pretty cool

So now it’s official, the ingredient in Sudafed PE, that everyone knows sucks compared to the original pseudoephedrine version, does NOTHING and is banned from sale. For years it’s all you could get because 15 years ago ppl would make meth from good Sudafed. Since then, meth made in Mex totally took over n no one would bother making it from Sudafed. But they kept the pseudoephedrine controlled n sold us a literal placebo, for years. It feels representative of the incompetence and slow response around COVID n opiates. Joker regulators, ghoulish capitalists

Co2 monitoring: This is the rarely discussed Netatmo Weather Station. At $179 it’s cheaper than Aranet and has an indoor co2 monitor/temp/RH and an outdoor unit temp/RH. Indoor unit is USB powered and needs wifi. Let me show you the awesome apps that let you pore over data… The default Netatmo app is adequate but the interface is too simple for serious ppl. It’s designed for broad user base of course. You can get detailed co2 history but it’s a little bit of a pain. Nevertheless all the data is there. But there’s a better way…

This is a compendium thread of all my builds where I actually explain with pictures what I did 😆. Let’s start with the easiest, the most essential version of a PC Fan mini #crbox

https://twitter.com/CRBoxKits/status/1557785594914168832

Same basic mini CR Box idea but using HEPAs

https://twitter.com/CRBoxKits/status/1543034613135601664

This is a thread of my favorite CR Box music videos I’ve made. So far I own the genre 😂 Best place to start: In the Air Tonight by Phil Collins. 🧵

Hi there, thanks for giving a s*** about COVID and clean air. It’s kind of hard to organize info on Twitter, but I’m making a pinned tweet to make it easier to find my builds etc. and see my favorite tweets. So here goes. I’ll update this regularly🧵latimes.com/california/sto… The above LA Times article about making CR Boxes features me and a lot of my older designs, from Aug 2022. It helps explain why I do this. Below is the video they made for it with more detail.

https://twitter.com/CRBoxKits/status/1560758161719455744

As we enter a phase of folks making mini DIY CRBoxes with stacked series fans, it would be nice to get some clarity on performance. The primary source used for putting spacers in-between for “performance” is one Noctua white paper, with one sentence about it and zero metrics: 🧵 It’s not a great sentence. “Directly towards each other” implies opposition, yet why would anyone do that, prob just bad writing. “Reduced aero-acoustical performance” is very vague, and possibly only about sound level. @DavidElfstrom is there a better resource for this info?

Since XBB15 seems to have an easier time infecting via your eyes, it’s more important now to wear protection. If I don’t wear my prescription glasses, I like this cheapo “stoggle” from Amazon. Comes as shades too. Has stealthy side shields. For all you non-glasses wearers They are the most normal looking cheapo safety glasses I could find. There are a few styles. $10 or less.

The No COVID Fandelier 2!

Smaller bottom filter aim fans 45° down so they light the table not the wall. More chandelier-like. Square, so good for sq/round tables. Figured out “warm white” which is nice.

12 fans, 660 cfm raw, 290 CADR. 2’x2’ top Filtrete, 16”x16” bottom #crbox Some stills n build pix. Song is @radiohead’s Everything in it’s Right Place. Again it’s a mix of fans so not a final design, just a first shot at my “different sizes” idea to get light onto the table

The No COVID Chandelier is HERE!
Just in time for Thanksgiving

18 fans, 990cfm raw, 2x 14x30 @3M Filtretes. 46db. Cleans the aerosols straight from up the table, spreads clean air in 360 directions at all the guests. #crbox

@yodelodwho @robwiss @Trematomus @mrlighttouch Fandelier has been coined by a few of you. I like it! The song is the inimitable Post Malone singing second half of his song Waiting For a Miracle which is just a freaking great vocal performance w/ best reverb ever. The view from dinner tonight, no guests just us:

Fresh #crbuild @robwiss mega-sandwich style. 2x @3m Filtrete 14x30, 12 (new record?) fans total, 6 Asiahorse s001 on top and 2x Matrix 360 3-fan units for the sides. 660cfm raw. 2 controllers for visual fx, overkill. Finally you can eat without worries 😄#crbox #corsirosenthalbox Some stills. I will try and post a complete parts list but I’d like to simplify it first, this was made from a bunch of stuff I had rather than tuned for ease of build

An easier to make and service 9 fan #ALPanel for you all! I realize wiring is the hard part so this is all just connector plugs, no tricky wiring and no controller. Added a plenum that makes swapping out the filter a cinch. And finally finger guards. Rainbow ONLY Details in 🧵 With all the parts, it’s like legos. Total around $140
-3x 3 packs Novonest Auto Rainbow 120mm fans
-14x14x1 @3M Filtrete MERV13 + Box it came in
-12V/3A Power Supply
4x 4-way fan connectors (Etsy)
2x 2-way fan connectors (Etsy, optional)
9x fan finger guards black
Black tape

Here’s a slim portable #ALPanel. 200mm 103cfm Coolermaster fan, 10x10 Nordic Pure MERV 13 + carbon. Black masking tape + 2 rubber feet. Easily fits in a bag or backpack, has much simpler wiring because it’s 1 fan. Leave the LEDs off and it just needs 1 normal USBA plug or batt It’s probably pretty low CADR, say 20-40, but it definitely cleans the air in my bedroom over time. Very quiet, basically silent, easy to sleep with it on. Fan is $29, runs off the simple power supply pinned on my profile.

@strongbeanBT The AH controller needs both 5V and 12V power. The USB to Sata cable you have only provides 5V, works with the in-line cheap controllers. You will need use the Asia horse power cable, clip the data connector, and wire up 12V and 5V separately. You can use my USBC design @strongbeanBT You need:
1 12V USB C trigger cable
1 5V USB A cable
2x 2.5mm barrel connectors female
65W USB C adapter with USBA and USBC
