There are four top level items that you seriously need to consider when getting started: food, water, shelter and security. There are many sub-items. You're going to want to create lists. Write each of the four items at the top of a blank page. Then start writing down what you think you need to survive in adverse conditions for a specified duration. Over time you will revise your lists and break items out onto their own pages. The exercise in creating the lists is important because we all have different concerns and needs. What is an absolute requirement for me may not even be something you would consider. There are a lot of resources on the internet to help you discover items for your lists.
I recommend that the very first step you take when prepping is to evaluate the most likely risks specific to your geographical area and your personal domestic situation.  Most, if not all, city, county and state governments will have emergency management websites that will help you sort through the most likely disasters to occur in your area.  Take advantage of these public resources.
People in the disaster preparedness community often say they are readying for the “shit hits the fan” moments: some future calamity, however plausible or implausible, when we are forced to fall back on our possessions and ingenuity. Doomsday Preppers, the long-running National Geographic show that popularized the term “prepper,” introduced mainstream America to a slew of quirky individuals — mostly men with a love of pricey gadgets and the Second Amendment — and the highly improbable doomsday scenarios for which they’d chosen to prepare.

Why not take it a step further and think, if you were in a flood, earthquake, or some other disaster or SHTF scenario where supply routes were cut off, and clean drinking water was not available, how would you try to mimic normal life and keep your modern comforts, let alone survive without relying on running taps, full grocery aisles, and electricity.

One factor, Mills argues, is that the organizations responsible for coordinating that emergency support tell them they should be ready to deal without it. "Federal agencies have recently encouraged American citizens to contemplate surviving disasters without their assistance," Mills writes, citing a previous study. And the government also warns people to be ready for risks that have never materialized. Since 2003, a group within the Department of Homeland Security has advocated that people "have a ‘safe room’, duct tape, and plastic sheets on-hand to secure their home against (unprecedented) chemical terrorist attacks."
Update: Yes, if you have prescription meds you’d die or suffer without, definitely pack an extra few weeks’ worth in your go-bag. And stick in extra glasses for anyone who wears prescription lenses. I didn’t add these because the former doesn’t apply to me, and I haven’t gotten around yet to buying the latter, but commenters have reminded me that these two things are at the top of the FEMA list.
It's that time of year, when charities do food drives for food banks and holiday meals. If you've got normal type food (maybe not your Mountain Home stash...) that you're just not gonna eat before it's expiration date, now might be a good time to contribute some of it to a food drive. Keeps it from going to waste, and allows us to help out the community.
A second motivation comes from the media, which tends to provide nonstop coverage of natural disasters and their aftermath. Mills said nearly every subject mentioned Hurricane Katrina, Hurricane Sandy, or both. Mills' road trip took place in 2014, and Ebola and ISIS both made frequent appearances in the risks mentioned by the preppers (as they might again today).
They looked at data for the local population over various periods of growth and change, and found that the entire central Mesa Verde area was depopulated by the early 1280s, says Kohler. Based on tree-ring data, the team knew that there was a long cold spell in the 1200s. By the time a great drought hit from 1276 to 1289, most people had already left the region.
I can’t agree with your solution for water purification. If the argument is to “also” include scenarios where boiling isn’t practical, there are other options that fit the bill. For us, we’ve been using a Berkey filter system in our home instead of something that needs water pressure or power to serve in both bug out and Flint, MI like scenarios. We use it day to day today. Not cheap upfront but the cost per litre/gallon over time is a fraction of what you’ve proposed – with all due respect.
I mean, how can you possibly deny the usefulness of one of these? I’ve spoken about it before in my article about staying indoors when the power’s out: having a brick room-sized shed/garage separate from the house and put a fireplace there is pretty much my idea of the perfect prepper space to create. And this is the wood-burning stove/fireplace that would go there. In my dreams of course, because first you need to have the right property, then the right garage/shed, then finally I can grab this sort of remarkably useful kind of thing.
While I keep almost all of my food in the basement, with only a small portion in the kitchen pantry, 98% of my basement food storage is in sealed cans, or in mylar bags stored in 5 gallon buckets. That way if my basement floods I can wash the cans with disinfecting solution (10% bleach solution) and relabel using markers. Upstairs I keep my emergency blankets since they aren’t impacted by summer heat where if I tried to store food in the bedrooms it would be at risk from summer temperatures. But as I write this I realize I need to move my water filter and water BOBs out of the basement and upstairs so they don’t get impacted by a flood. Thanks for making me think of this!
There are a couple of options here. First, I will go with what I use. I recently moved from using a 100w Paxcess battery to use a much bigger Goal Zero Yeti 1200w system which is more capable of powering most household items. While I found the Paxcess really good to use as a backup power source for camping, or for working outdoors, I found that it only powered a few items. The Goal Zero system is much more efficient at powering most of our home needs and is an effective competitor against fuel systems but is much more efficient as it can receive a quick charge from solar panels, and makes next to no sound, unlike fuel-based generators.
It is a step that most preppers take in the move from cheap bottled water from the supermarket, to storing your own water in your own containers. It makes a lot of sense as well as we really do use a lot more than we think in our daily lives, whether it be to wash the dishes, shower or flush the toilet. All of those daily activities require a lot of water so storing more than necessary actually isn’t a bad thing, provided it is stored properly.
Anyway, another thought runnin’ round my brain as of late is a mistake Gaye’s friend did, “Yes, you can use oxygenators and all that stuff. I tried that and I ended up throwing out all the food. It was rancid. I processed $1,200.00 of food at a local church facility in Salt Lake City, Utah. I threw it out one year later. It was a volunteer church group that did not know how many oxygenators to put in each #10 can.” – //
Anarcho-primitivists share many characteristics with survivalists, most notably predictions of a pending ecological disaster. Writers such as Derrick Jensen argue that industrial civilization is not sustainable, and will therefore inevitably bring about its own collapse. Non-anarchist writers such as Daniel Quinn, Joseph Tainter, and Richard Manning also hold this view. Some members of the Men Going Their Own Way subculture also promote off-grid living and believe that modern society is no longer liveable.[107]
This is a good assortment of easily prepared food for camping or emergencies. That said, this will not feed an adult for one month. If I have done the math right, there are 19,560 total calories which equals 1956 calories per day for 10 days. So, three of these boxes would feed an adult for a month, if that person was doing only light physical activity. Also, the food bags are not re-sealable, so you should add some quart-size food bags to the box.
