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 ImageImageImage
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. ImageImageImageImage
I have a more powerful fan this size but it’s a lot louder. I prefer this one for the silence. I’m going to make a few new portable designs, ones you can actually put in a bag as that seems to be really sought after rn
You can see the other fan in this larger panel I built. I found at night I had to turn off the smaller/louder fan. So I chose the quieter Coolermaster fan for the portable; the louder Silverstone fan definitely delivers more CADR, rated at 143 vs 103 cfm.
Bedside. I put feet on this one because without them the fan has to drop down from it’s perfect position in the middle of the filter; taping it up so the fan&filter are flush at bottom (but off-center) would make the feet unnecessary Image

How to make an easy home FIREHOSE!

I’m in the middle of the LA firestorms so I’ve tried to get more prepared. Wanted the fastest, easiest “firehose” I could get without a plumber. I learned a lot so I want to share it with y’all. It’s much easier than it sounds! A 🧵 Garden hose firehose
Actual fire hoses are 1”-5” and need special plumbing.

The goal here is to get maximum performance from your existing garden tap.

Garden Hose Thread GHT is 3/4”, but garden hoses have internal diameters of 1/2”, 5/8” and 3/4”.
So for a firehose garden hose, everything needs to be 3/4” with no choke points. That’s the feed, hose, valve and nozzle are all specifically 3/4”. You can just buy the last 3, but the feed has to be big enough to begin.

I found an easy way to add HEPA to the MiniVOC filter. Again, very easy to build and way way more carbon than normal HEPAs.

With the HEPA it drops to 38db. Build directions 🧵 Completed MiniVOC+HEPA
The HEPA
This is the HEPA filter. It’s $9 but gotta buy 2 for $18. It’s exactly the size of the 120mm fan. All we are going to do is tape it in place. Everything else you need is in the quoted thread in the OP
a.co/d/1rB3red
The fan pulls through carbon, then HEPA for all particulates/virus but also to stop carbon dust. The HEPA has a carbon layer of its own which won’t do much but the fan is much quieter placed against the carbon side of the hepa. Either direction works tho, if the filter is new. Carbon layer side of hepa, will face the fan
Correct layering of elements
The premium air stack, ready to be taped
Tape the fan to the HEPA, then tape the whole thing to the carbon filter. Done

MiniVOC!

I ordered the smallest, highest cfm 120mm Silverstone AP fan n replaced the fan this 4” carbon unit came w.

Now it’s 43db on high and much more usable. $45.

Came with a fan so I used its screws, but tape works. It’s a true mini version of the MegaVOC. 4” carbon filter with 120mm Silverstone AP
Mini and mega VOC filters
The cheapest 4” filter. It’s $25. AC Infinity makes a $50 version that’s much sexier but this build is for best bang for buck

a.co/d/6G27Eml
The fan is Silverstone AP 120i-Pro. 74cfm, 2.52mm. It’s $20. They make a slower one 45cfm for $9 but the extra cfm is needed imho

Happy New Year!

A thread about one of the best CC lifestyle things I got: an outdoor heat lamp.

Having the ability to really blast heat outside has meant many friends/family visits at temps 2 cold for outdoors were totally enjoyable. But not just any work well…🧵 Standard patio heater on blast in an enclosed patio
First of all, forget electricity. Plug-in 120v electric heaters top out at 5000 BTUs of heat. Patio heaters running on gas put out 10x or 50,000 btus. For heating the outdoors w friends you want as many btus as you can get. It’s gotta be gas.
The 3 main types I’ve tried: standard like in the first pic, quartz tube pyramid and fireplace style. All 50k btu. Standard works best by far to focus the heat onto the people. The others look cooler and ARE cooler. Cheap or expensive standard patio heater is the way to go

HUMIDIFIER rant/reco:

I’ve read a few new articles about humidifiers that sound good but end up with bad advice.

For clean air, the best solution is an EVAPORATIVE Humidifier with bacteriostatic solution added to the tank.

Any other kind is risky IME/HO and I’ll explain. 🧵 Vornado Evaporative Humidifier EV200
To start: all humidifiers are fairly high maintenance. They need to be filled and cleaned every few days. There is no way to avoid that. But it’s worth it for the best indoor air. If you have HEPA and carbon already in place it’s the finishing touch. Helps fight COVID too.
Ultrasonic and impeller humidifiers put *everything* that’s in the water into the air. Minerals, vocs and bacteria. Ideally, but unlikely, you use distilled water, which is expensive at this scale (gallon per day or more). And bacteria grow fast, then enter the air. NO!

MegaVOC filter!

It’s been a while! Here’s a new easy build that’s absolutely the best way to get VOCs filtered. Lowest cost, quiet, 140cfm. It’s an 8” grow filter n a Silverstone 180mm fan. Plus usb power and black tape.

$132

This is for @LazarusLong13 @Ikat0 @AltenbergLee Big VOC carbon filter with 180mm fan
Wide shot of VOC filter in a bedroom
So first off, the grow carbon filters are about $4/lb of activated carbon, cheapest deal. They can be all black n fairly sleek. For tackling smells for years nothing beats em. Years. This brand is great; all work. 8” has about 22lbs carbon inside for $89

a.co/d/dtOGmYR
The fan I really like is Silverstone 180mm. But any 180-200mm PC fan will work. This one is the AP184 with 143cfm; avoid the similar price AP181 with only 100cfm. $32
