Halsa EMF Protection for Laptop Computer, Faraday Computer Case, 99% EMF Reduction. Protect Your Lap, Shields 5G, 4G, WiFi, Bluetooth. Fits Most Laptops, Carry Inside Briefcase, Backpack, Purse

The Swedish manufacturer Halsa suggests how to check to see if their EMF blocking bag works. Just so happens I have all the components needed to perform that test. I used my Erickhill RT-100 Electromagnetic Tester to test electronic fields in V/m. With alarm set to on, I placed the RT-100 inside the Halsa bag, and zippered the bag closed. I moved the bag and tester close to (actually on) a known high level EMF producer and listened to hear if the RT-100 detected an EMF at 40 V/m or higher. Nothing, no sound from inside the bag. All I could prove was that the RT-100 did not reach the threshold of >= 40 V/m.; However, based on the known source which produces a EMF signal >400 V/m, I feel confident the bag does afford significant protection. Enough to act as a Faraday bag against an EMP? I do not wish to be a witness to say that it does. My laptop is inside the Halsa bag, and there it shall remain. By the way, the bag was a perfect fit, both for the laptop and my laptop carry bag.

Product promises to stop 99% of all MmF but does not stop any of it. It is a fraudulent product

I ordered this EMF blocking sleeve mainly to use under my computer because I frequently like to work with it on my lap, and I was tired of being exposed to potential radiation so close to my body. You would think radiation comes out the front just as much, but the underside of a laptop is one of the most potent sources of high-frequency EMF radiation from what I read in studies. This cover is large, thick, durable, good quality so also works great as a sleeve to protect your laptop from outside sources that could damage it.

This product is an oversized, neoprene style bag that is not quite as protective as a true Faraday bag, but can shield your expensive electronics from a lot of electronic impulses. The fact that it has a standard zipper already means that a small amount of energy can penetrate into your devices. A normal Faraday bag has a unique fold-over design that completely seals the products in. A zipper alone would make it ineffective.Overall it is a nice sized bag for your laptop, tablet, cell phone, and basic accessories for each. It is also a good way to keep them together, and separate from other things such as pens or food that might be in your bag that could get your expensive items dirty. It also adds an additional layer of water protection, and certainly it's nice to have all your things in one place.Other than the fact that it is not a true Faraday bag, it is pretty nice. It keeps expensive things safe, and it's large enough to fit all of them in one place.

No, can’t bring it in the houseI imagine if there was an air quality meter nearby this thing on the reading

I got this for my laptop on the off chance an EMP could actually happen. I haven’t tested it yet but other reviews said it works good, and I’ll come back to update this if it doesn’t work properly. It’s a massive case and will fit my laptop along with a tablet and phone inside of it. I’m excited to have it “just in case”.

This laptop sleeve is a good safeguard for individuals and their computers. It is soft and nicely cushioned. It's the ideal size to put in a tote. The zipper runs smoothly. It does not matter if it gets wet. The black color goes well with other accessories. This is a useful laptop sleeve.

This is going to help keep radiation away from me from the laptop, tablet and cell phone. I think this is a great idea, as I think you Oughta try to protect yourself from all this radiation our devices e m i t over the long term of someone's life . I think it's probably a good idea to try to limit these frequencies from going through your body. That's why this is a good idea. Good old Faraday, he knew what he was doing right?
