With respect to the Multipure filters, I had a few cautions and concerns. Some (like the expensive whole house filter and the portable water bottle filters) aren’t even designed to remove serious chemical pollutants – they’re only good with already-treated municipal water sources. And while the specs of some of the other filters appear excellent in terms of removal of a long list of chemicals, they’re still only good with water supplied under pressure. From a health standpoint, that’s excellent, of course. But what about a survival situation, where municipal water no longer flows from the pipes in one’s comfortable home?

I looked at the “wriggle Portable Filtered Water Bottle” and noted that for $49.95 a person only gets better tasting water, basically. Yet for around $20-25 one can purchase a LifeStraw and be able to survive in ANY situation with ANY water source, essentially. The “wriggle” only removes or reduces bad tastes, basically, whereas such things as the LifeStraw remove a comprehensive list of chemicals and other contaminants from any kind (or source) of water, including a scummy pond, a gutter, etc. Even those little $25 units will filter up to 1000 liters (264 gallons).

We have chosen to simply fill the top bucket in a homemade Black Berkey filter system with 3-4 gallons of water at a time, and allow that to gravity feed into a 5 gallon bucket on the bottom that has a valve installed on the bottom bucket. It supplies all our drinking and cooking water. Not only is it the best tasting water of any source we’ve ever tried (the finest of the store-bought spring water is no better than this), we can take it elsewhere or even use it if sheltering in place in our home, with no pressurized water source. In a SHTF scenario, there may be no “running” water except that which is “running” in streams and rivers. Then a gravity feed system (or else something like the “LifeStraw” type filter), with a high-quality filter becomes essential – one that removes a long list of chemical contaminants, bacteria and other critters, etc. If the situation warrants survival in our own home but with no municipal water, we’ve got our previously discussed 275 gallons of “raw” water from the roof, replenished with each successive rainfall, and the gravity feed Black Berkey filters when we actually need to drink/cook with it.

(By the way – I noted that the Multipure whole house filter mounts near a water heater. In many houses, the incoming municipal water starts feeding the entire house FAR from where the water heater is. In our situation, the water enters the house near the front, the main shutoff is in a front bathroom, and the cold water supply pipes branch out from there in the concrete slab that runs under the house. The water heater is in the far back corner of the house in a utility closet. Hooking up a Multipure whole house filter at least in our house would only filter the water going to the water heater, thus only supply the hot water outlets. And even then, that filter is only a basic filter, NOT one for extreme filtering of all sorts of chemical contaminants, per the company’s own statement. Read specs carefully if choosing ANY system or device. Personally, after extensive research, we’ve chosen the Black Berkey filters, not even their ceramic or “budget” filters, and I have yet to find any that exceed their specs at a price that could even remotely be considered reasonable for most people. Plus, they last up to 6000 gallons per pair, regardless of how long they’re in place.)
