You could but that would place the filter inside closer to you and that would expose you to more radiation from the filter. There are many ways to position the filter you just have to think through the consequences. Thanks for the comment.

Thanks for the info

Most homes will not be near enough to be damaged during a nuclear explosion. The explosions, although destructive in the immediate location, do not affect that large of an area. Maybe a 10 mile radius. You are much more likely to be affected by the fallout that can cover hundreds of square miles. But if you are unlucky enough to be experience the actual blast that could topple your house, you are probably toast no matter what you do.

The one for aquariums should be fine. There is not a lot of difference. They add some coating to make it more effective but it will still be effective.

I do not know the ppm concentration it is difficult to measure without more expensive testing equipment. To increase the concentration you just have to leave it in longer. Most people I think base it on the color to just get it close. Thanks for the comment 👍

@@edwardjackson9791 so I just went through some other sources, basically the silver does not dissolve completely hence TDS meter will not show accurate reading but still should be enough for my use. Thanks so much

The placement is dependent on your shelter design. It would be best outside. Or in a space inside like a garage that would protect it from the elements. You could also shield it if you wanted it inside your shelter area. Thanks for the comment 👍

It actually goes on the discharge side of the blower motor shown in this video kzbin.info/www/bejne/e5ekfGSmos2qjassi=srFF4I72f7azA0rK You could make to connection inside your shelter with what ever size piping you have. The bottom side would hook to the filter discharge and the upper outlet would go into your shelter area.

This is the link is to the full video but I wanted to make one for the activated charcoal filter build. kzbin.info/www/bejne/e5ekfGSmos2qjassi=srFF4I72f7azA0rK

It is at 27Vdc. That is the same as used for colloidal silver. I haven’t seen any other voltage but I just use it for disinfecting surfaces. Thanks for the comment maybe I’ll lower the voltage and see what effect that has.

@@edwardjackson9791 current = amps. Your voltage is fine but the intensity/amperage in which the voltage is being pushed through needs to be regulated. Using a battery setup is fine as long and you use a potentiometer. This will regulate the amperage with ohms. 27v with high ampacity will cause particles of metal to fly off the rod. You want the smallest particles possible as to go beyond the blood/brain barrier. There's an older fellow here on youtube who rigged a box with potentiometer and banana plugs. Check him out.

@@josephdelange8497 thanks I see if I can find him.

Sounds good. One thing is make sure your flow rate is low, just enough that would keep the area you would be in to about 0.25 inches of water above outside air pressure. The contaminated air needs to be in contact with the activated charcoal for at least 1/4 of a second to remove the contamination. So, too high of flow rate would not allow the contact time needed. Thanks for the comment.

I have done other videos on what you asked about just look at the videos on my channel. But it would be best to install it outside the shelter I’m a protected area for example if your shelter is in the basement installing the filter in the garage would protect it and you would not have to exit the house if something needs adjusted. There are many ways to manually pull air through the filter. I did a video on one I built with a large PCV pipe and connections. Again if you look at my videos on my channel you can find them. I don’t have that many.

I would think this type of filter would be good for about a month. We have these type filters in nuclear plants and they are not all that big and are normally good for 30 days. Of course that depends on the air quality and contamination levels. If it is extremely dusty the dust alone could plug the filter. So having some sort of pre filter would be very useful to extend the life of the filter. Also using it at low flow rates will extend the life but you need to normally have a slight negative to neutral pressure in the shelter.

You can use HEPA on both sides of the activated charcoal but the inlet can just be regular HVAC type filter to catch the big particles before entering the activated charcoal bed so it won’t plug. The charcoal does some mechanical filtering but its primary purpose is the trap and hold up the radioactive gases that can’t be filtered. This is called adsorption. The radioactive gas can then decay to radioactive particles which can then be filtered out by the exhaust HEPA Filter. Yes a positive pressure is best about 0.25 inches of water pressure is enough. The filter would best be outside the bunker but somewhat protected(i.e. in a garage as long as it it not close to your shelter). The filter will become more and more contaminated but this type filter would probably last at least a month and by then it would likely be safe to exit the shelter. And during that time the filter would also be decaying as time goes by.

Yes this is just the charcoal filter part. It would fit inside the outer bucket that has holes, HEPA Filter, fan, and roughing filter material. So if you look at the video I did before this is just the charcoal filter part. I was still trying different designs to make it easier. I am not really interested in selling any I just want to share the ideas based on what I’ve learned. I’m sure there are many ways to skin this cat. Thanks for the comment.

@@edwardjackson9791 Thank you for your hard work. Our families are grateful

Totally true. Thanks for the comment.

I go by the color but there are other videos out there that go into more detail on the process. I just use it for external use as a sanitizer. Thanks for the comment.

Every filter will be radioactive if used to filter radioactive fallout. This type of filter will probably not need to be changed out for a single event. It should last for several weeks or months. Yes you need to have it far away, like outside or very well shielded if inside. If the filter adsorbs radioactive contamination that could give you a lethal dose when changing it you probably have already received a lethal dose from the event. You must remember the filter is decaying just like the radioactive fallout. It is a fairly rapid decay. So the filter will last several weeks and changing will be unlikely and if it is needed a lethal dose is not a real possibility again unless the contamination radiation levels were so high that you would have already received a lethal dose from fallout itself. Thanks for the comment.

Thank you for the comment. If you look at my channel I build a simple air pump with 6 inch pvc drain pipe which can be used basically as a bellows. The water I talk about is a measure of differential pressure normally used on HVAC systems. If you have a filter for example and measure the pressure difference from one side to the other it is in inches of water. So if you take a clear piece of tubing and make a loop (like a p trap under a sink) in it and connect it to the inlet and outlet of the filter then water when air flow goes through the filter the water in the tube will displace based on the inlet and outlet pressure. If you measure the difference in the water level with a ruler it gives you the inch of water. There are plenty of KZbin videos. Here is one. kzbin.info/www/bejne/epWuaZprjcSLd9Esi=LMQJuRvbp7HkEekM

The design is for an NBC filter for filtering during emergencies but can be used for clearing odors from air. I ordered the HEPA filter for a vacuum cleaner (craftsman shop vac) from Amazon. About $30. I have another video on the complete build and others for the use on my channel if you would like to see more about it. Thanks for your comment and sorry it took so long to respond.

Thanks for the comment. I don’t know exactly what screw you are taking about and my chain saw is in another state so I wouldn’t be able to look at mine to help you on that. Sorry.

@@edwardjackson9791 I mean, how did you remove the screw at 1minutes and 33 sec? The srcew with the metal rod. Sorry for my english

@@axzelothat is the drive gear for the oil pump. The wire arms are driven by the clutch drum. It should just pull straight out. Just wiggle it and pull straight out. It fit with the gear on the oil pump to drive the pump. Hope this helps and if you have any questions please post and I’ll try to answer if possible.

Thank for the comment

Yes distilled water is what I use BUT I used for medicinal also. If just using for a pool I don’t know if that would be needed. I am sure the voltage will affect the time it takes. Not sure if the particle size would be affected. I am not familiar with using it for pool water. Thanks for commenting.

distilled water isn't just best, it's necessary. If you have minerals in your water, the silver will react with it.

@@WillBilly425 that is what I thought would happen. Thanks for the feedback👍

That is pricey. The one I used was around $30. But it depends on your needs and design. Thanks for the comment 👍

Good idea. The shape of the bucket or container really doesn’t matter as long as you don’t have leakage past the filter media. The only requirement for flow rate is it provides enough makeup to supply your shelter with makeup O2. The air flow should be in contact with the activated charcoal flow >0.25 seconds. So slow flow is better if it provides the correct amount of makeup O2. I bought a CO2 monitor to check the air in our area.

I use silver Canadian maple leafs because they are 99.99 % pure . They will probably last hundreds if not thousands of batches.

@@edwardjackson9791 thank you sir

@@edwardjackson9791 also, Semper Fi Devil Dog

Great point!

I am not sure. Are you using pure copper? Mine is .9999 pure copper. I used the same voltage as you but using a power supply. I don’t think that would matter. I’m not sure what you are using it for either. I used mine for just disinfecting. Sorry it took so long to get back to you.

Thanks for feedback 👍

That is correct. When I removed the old pump I marked where the suction grove was so I could install the new one correctly. Also check the depth so you get the new one back in and aligned with the discharge hole. It is not to hard to get the depth correct because the pump gear has to align with the drive gear and you can see it on the clutch side pretty easily. Check the video at about the 3:15 point where I try to explain it. It is hard to see because of the small sizes. Hope this helps

@@edwardjackson9791 I didn't mark how mine came out, so now I don't know to line it up.

@@hagsmich ok . If you have the same saw, when you are installing the pump the saw will be upside down. Have the saw throttle pointed toward you and the bar would be point away at the 12 o’clock position. The groove (suction side) in the pump will be located at the 6 o’clock position. The discharge hole ( one without the groove ) will be at the 12 o’clock position. Again this is with the saw upside down looking at the bottom. When you are done and the saw is back together run the saw with no bar so you can check the you have oil flow. If you don’t have flow I think you can adjust the pump from the bottom without taking the saw totally back apart just remove the suction tube from the pump suction and adjust the position. Hope this helps. Good luck. Send comments on if this helped and any thing you learned so others can benefit 😁

Thanks for your help.

@@hagsmich 👍

I just did it until it was a light blue color. About 24 hours. But I was using 27 Vdc. Unless you are shooting for a specific concentration I think that the color is a good indicator. I am not at all an expert on this I just enjoyed the process and the visuals. There are much better KZbin videos on the process.

The fan I used was not a shop vac but that could be used. The full flow would likely be way too much. The air needs to be in contact with the activated charcoal for about .25 seconds or more so you can throttle the discharge to reduce the flow. I used an old squirrel cage fan from an old gas furnace. If you look at the other videos on my channel I cover manual operation and some design ideas. The good part of the squirrel cage design is there is little resistance to air flow and if you need the manually operate a air pump it is much easier to pump air through. Thanks for the questions.

This video covers more about this type filter. kzbin.info/www/bejne/e5ekfGSmos2qjassi=eXDIqtNPVy8cpkvo There are a couple of more I made that explains more.

Thanks that’s good information. I did it mostly because it was interesting but we do use the colloidal silver for cleaning. There is confusion (at least on my part)as the the ppm you get and an exact way to measure it. Thanks again for sharing.👍

Thanks for sharing

Good idea!!!

So what part was wrong?

@@edwardjackson9791 reread my comment it’s clearly stated

www.merriam-webster.com/dictionary/nuclear?pronunciation&lang=en_us&dir=n&file=nuclea01 nu·​cle·​ar ˈnü-klē-ər ˈnyü- nonstandard -kyə-lər How do you pronounce nuclear?: Usage Guide Though disapproved of by many, pronunciations ending in \-kyə-lər\ have been found in widespread use among educated speakers including scientists, lawyers, professors, congressmen, U.S. cabinet members, and at least two U.S. presidents and one vice president. While most common in the U.S., these pronunciations have also been heard from British and Canadian speakers. There has always been variations in the pronunciation of nuclear. Again what part of the Video was factually wrong?

It has been a few hours for you to review the video for any actual errors and I am assuming you have no others. Thanks for your input and if you have any other comments that add to the discussion they would be appreciated. Bless your heart and have a good day.

Non-standard because it’s wrong. A lot of people pronounce it incorrectly. However if you’re going to present yourself as knowledgeable on a topic and expect people to believe you know what you’re talking about you should pronounce it correctly. It just makes your entire presentation sound unqualified

That is difficult to say. It depends on how air tight the space is and number of people. The key is to provided filtered makeup oxygen to your space as long as you provide a slight over pressure (.025 in water) with most air flow though the filter it will provide protection. The filter elements used at nuclear plants are not much bigger that a couple of trash cans and provide air filtering of around 50,000 ft2. So it mostly depends on how much makeup air you need not the volume. This filter is not perfect but it will provide better air quality that just a furnace type filter. The ones that are specifically built for this are in the $5000 dollar and much much more. But the filtering is the same. Hope this help. Thanks for the comment.👍

Never herd of sq ft water perhaps gallons and this guy would't know

No.

You can use 9 volt batteries or any dc power supply that you can control the voltage. There are videos on using the batteries on KZbin.

Voltage is 27.5 Vdc. Current will be based on water purity.

Not sure. You can look at safe cell for specific filter details.

@@edwardjackson9791 thanks

Copper bullion bars

Best place is outside under cover but inside like a garage would work. You just have to realize it will be drawing contamination inside the area you put it. Also away from people. The filter itself may become radioactive as it filters and present a radiation hazard. Thanks for the question 👍

That be great. My problem was the original pump had no treads so I had to push it from the top. Wasn’t hard but the replacement pump had threads and it would have made it much easier. Thanks for the comment 👍

Thanks for the comment. Not sure your thought process though 🤔

I use 99.99% copper bars.

@@edwardjackson9791 Thank you so very much!

I’m not sure what you’re saying there? Are you saying you can’t hear me mumbling or because I’m mumbling you can understand, or can’t hear me because someone is mumbling too loud? Appreciate the feedback but not sure what to fix.

I know it is hard to measure the colloidal content. It is not as straightforward as measuring the change based on like adding salt or other substances. I looked on the internet and it was different with colloidal copper and silver. I never did get a good answer. I make the copper and get a bluish green water color and use it for disinfecting surfaces and like my hands. But I don’t take it internally. The silver is a bit more tricky because it starts out straw colored but turns darker and gray over time. That makes since because that is the process in photography. The silver in the film when exposed to light turn darker the more light it receives. Sorry I can’t be more help but unless you have sensitive enough and the correct kind of equipment you may just have to estimate based on color.thanks for the question and if you find an answer please post it for me and others.

it's because TDS meters aren't meant to measure colloidal contents. they are calibrated for 100ppm and higher. they round up and down by 2ppm, for example a 1ppm solution could show as 0ppm

The batting (roughing filter) on the inlet is good and helpful to prevent plugging. The reason for the carbon first is it captures radioactive gases and holds them up for a long period. The gases pass through any filter. The carbon traps the gases and allows them to decay into fission particles which the filter can then remove. As for amount of carbon, the beds at nuclear plants for the control room were 2 inches deep beds. But the important part is the air flow through the activated charcoal should allow at least .25 seconds of contact time so you want a flow rate that allows that contact time. In reality you probably don’t not a lot of air flow. I have a CO2 monitor to make sure there is enough makeup flow. The activated charcoal will probably last a very long time so the limiting part will likely be the HEPA filter. But this system would likely be good for over a month and if you are just using for makeup flow it would likely last much longer. For the cost you could make spares that you could exchange if needed. Hope this helps. Thanks for the questions.

It still working great. You get a small amount of vapor but it is drastically reduced. I did change the connection to the pump. I took the cap that came with the pump and after modifying it to fit on the PVC pipe I JB welded it to the PVC pipe so it would fit better to the pump. The fitting on the pump is some really odd Chinesium size.
