Product description

Filtering water for a family one mouthful at a time is not a plan. The Gravitywell is the household-scale answer: fill the 1-gallon reservoir, hang it from a door or a branch, and gravity pulls the water through the filter while you do something else. No pumping, no power, no standing there.

During a boil-water advisory it quietly turns the bathtub reserve into drinking water. On a campout it does the same for the creek.

Honest limits, same as always: it removes bacteria and protozoa. It does not remove viruses or chemicals. When those are the risk, boil or use tablets.

  • Model: Gravitywell GW-1G

A live tracking link lands the moment it ships. Larger orders may come in more than one package so nothing waits on anything else, each tracked, no extra cost.

“I bought this for hiking and emergency preparedness, and it has already proven useful. I tested it on a weekend trip at a creek and the water came out clean with no strange taste. The first sip takes a bit of effort, but after that it flows easily. The included pouch and hose are a nice bonus for filling a bottle. Feels well-made and I’m confident keeping it in my pack.”

Verified Rating

“Really solid little filter. I keep one in my car and another in my go-bag. Used it after a storm when our well water looked cloudy, and it worked without any issues. The carbon stage improves the taste noticeably compared to other straws I’ve tried. Lightweight, simple to use, and the lifetime warranty gives peace of mind. Highly recommend for anyone who wants a reliable backup water source.”

Verified Rating

“This is one of the better personal water filters I’ve owned. No batteries, no pumping, just dip and drink. The 0.1 micron membrane gives me confidence when the water source isn’t clear. It’s easy to maintain and the build quality feels premium compared to similar products. I’ve already recommended it to several people in my preparedness group.”

Verified Rating

“I was skeptical at first because I’ve tried cheaper filter straws that clogged quickly. This one feels more substantial and the filtration is clearly better. I used it on a multi-day backpacking trip and had no problems with flow or taste. The backwash syringe makes cleaning easy. It’s now a permanent part of my outdoor kit and I’ve already ordered a second one for my wife.”

Verified Rating

“Excellent product for the price. It’s compact enough to throw in a daypack but still filters effectively. I tested it on lake water and the difference was obvious. The accessories (especially the collection pouch) make it more practical than basic straws. Shipping was fast and everything arrived well packaged. I’ll be buying more as gifts for family members who camp.”

Frequently Asked Questions

How is this different from the Field Straw?
The straw filters as you drink, one person at a time, straight from the source. The Gravitywell fills a bag that you hang, and gravity pushes the water through into a container, so you can fill bottles and pots for a household. The same filtration limits apply to both.
Do the filters remove viruses or chemicals?
No. Our filters reduce bacteria and protozoa. They do not remove viruses, heavy metals or chemicals. We publish that on every product page, because a filter that is oversold is worse than no filter at all. If you need virus or chemical removal, we would rather tell you now than after you have paid.
How long does delivery take?
Most orders arrive 7 to 14 days from the day you order, not from the day it ships. Shipping is free over $75 and a flat $7.45 below that. You get a live tracking link the moment it ships. Larger orders may arrive in more than one package so nothing waits on anything else, each tracked, at no extra cost.
What if it is not right for us?
You have 30 days from delivery. Email support@strongholdoutfitters.com with your order number and send it back for a full refund. No restocking fee and no reason required. If it arrives damaged or wrong, send a photo within 14 days and we replace or refund in full, your choice, and you keep the item.
What is the free Field Manual?
Three plain-English guides that arrive by email within minutes of ordering: The First 72 Hours, Prepared for Tuesday, and The Household Water Workbook. They come with every order, including a single item.
