Gear Review: The SolarBag Water Purifier

Gear Review: The SolarBag Water Purifier

One of the first rules of preparedness is to ensure that you have an adequate supply of water to sustain your drinking, cooking and hygiene needs in the days and weeks following a disaster.  To that end, I am positive that we each do the best we can given space and budget constraints.

Now what if I were to tell you that with a 4 ounce BPA free plastic bag and some sunlight, you could take raw water and purify up to  2 gallons of water a day?  Impressive right?  Well there is more.  What if I told you that the same bag could be re-used hundreds of times.

Solarbag Water Purifier

Today I would like to introduce the SolarBag Sunlight Activated Reusable Water Purifier. Plus, in keeping with the Summer Survival Blast, offer one Solar Bag for free to a lucky Backdoor Survival Reader.  More about that in a moment.

The Puralytics SolarBag

First let me tell you a little bit about the SolarBag itself.

It was developed and is manufactured here in the United States (Oregon actually) by Puralytics. It is simple to operate, using only sunlight to activate the nanotechnology coated mesh insert to purify water. No chemicals or pumps are required, and it can be reused hundreds of times.  Best of all is so easy to use that a child could do it.

According to the specifications, it filters out all sorts of contaminants including bacteria, viruses, protozoa, pesticides, herbicides, petrochemicals, pharmaceuticals, arsenic, lead and mercury.  Read through that list again because it is important.  You did know that typical particle filters, tablets, and even boiling, do not remove the chemical toxins in drinking water, right?

Rather than tell you how it works, let me show you.

Adding non-potable, non-drinkable water into a bucket.  This is the “free” water we use in our garden.

Fitting the Filter

Fitting the included filter bag over the top of the bag.  The filter is attached to the bag and is also reusable.

SolarBag Adding Water

Adding water was easy; I just poured it into the bag using a water pitcher.

SolarBag Tea colored water

Tea-colored raw water – definitely not drinkable.

Adding blue timing drops

Since this is the first time using a SolarBag, I added a drop of the included blue drops to turn the water blue.  When the water is clear, the purification process is complete. You only need to do this once for each type of weather condition.  The purpose is to let you know how long the purification process will take.

SolarBag Ready to Go

Set the SolarBag out where it will be exposed to sunlight or open sky.  It should be purified in two to three hours on a sunny day, or four to six hours  on a cloudy day or if the source water is tea colored like mine.

If you are interested in more detailed instructions, you can download a fact sheet here.

The Final Word

I had no idea that something like this even existed.  It is so easy to get caught up with the need for solar panels to power electronic gizmos that we forget that the sun can be harnessed for other, equal if not more important uses.

I was impressed and I know you will be to.  Don’t forget to enter the giveaway!

Oh, and by the way, the SolarBag is featured in the new movie, Dawn of the Planet of the Apes, opening this week.  How about that for good timing?

Enjoy your next adventure through common sense and thoughtful preparation!

Spotlight Item:  The Puralytics SolarBag Water Purifier is an easy to use water purification system that is lightweight and portable.  Where is really excels is in removing contaminants from water, plus, it can be used hundreds of time.  Highly recommended!


Almost Free:  How bad can it be? 3 in 1 Survival Whistle with Compass Thermometer. (Be sure to select whistle from the drop-down box.)

Cheap Whistle Works Good

12 Color Pack Bandana – Assorted Colors:  This is the #1 seller in the bandana category. Heck, I think that beats Wal-Mart and flea market pricing. Be sure to read How to Use a Bandana to Save the Day.

Morakniv Craftline Q Allround Fixed Blade Utility Knife: Also known as the Mora 511, this is now my favorite knife.  It is made of Swedish steel and is super sharp.

Magnesium Fire Starter:

UCO Stormproof Match Kit with Waterproof Case, 25 Stormproof Matches and 3 Strikers:  The UCO Stormproof Match Kit is waterproof and holds 25 matches as well as spare strikers. The matches burn for around 15 seconds and are windproof, waterproof, and even continue burning underwater. An integrated striker is attached on the side of the match kit, and can be replaced when worn out.

2 Pack Survival Kit Can Opener, Military, P-51 Model:  These can openers makes great addition to any survival, fishing, hiking, or camping pack. They are lightweight and robust and they just work.

Grabber Outdoors Original Space Brand All Weather Blanket:  I was interested in a re-usable emergency blanket so I purchased one of these based upon the excellent reviews.  This space blanket is definitely “heavy duty” compared to the cheapies (not that they don[t have their place.  A Backdoor Survival reader passed on this tip:

We place one of these blankets silver side up on our mattress underneath the fitted sheet or mattress cover.  It reflects body heat like you wouldn’t believe, instead of the heat being absorbed into the mattress.

Emergency Essentials Potty

Tote-able Toilet:  I have priced purchasing the bucket and toilet seat lid separately and found that it was more economical to pick up this kit.  I have filled my portable potty with sanitation supplies plus, of course, plenty of TP.

Dorcy LED Wireless Motion Sensor Flood Lite: I have two of these and feel that these lights are worth double the price.  Using D-cell batteries, the Dorcy floodlight will light up a dark room or a dark stairway in an instant.  I can not recommend these enough.

Silicon Power 8GB Flash Drive, Gray Aluminum:  I just purchased this flash drive for my key ring because the one I purchased a couple of years ago broke.  The flash drive itself works but the key ring thingy made of plastic broke off.  This flash drive has a ring shaped metallic exterior which should stand up over time.

  1. I also would love to win one of these. If not, then it is on my “to get one as soon as I have saved up enough money” list. As a fellow Washingtonian I am really learning a lot here. Enjoy the heat 🙂 Actually I do not so my face is :-(. Peggy.

  2. I currently have a Sawyer Mini, a ceramic pump filter, chlorine drops, and tablets. None of which remove toxins. And, of course, there is also boiling, which only kills pathogens.

  3. we do not have anything as of now so this would be a good start like that it is so easy ND NOT HEAVY AS WE ARE in our 60s and 70s

  4. We have our own well, which has great tasting water, but we do extensive camping. I’ve been looking for solutions to hauling in large amounts of water. Not to mention it would be a great addition to my Preps!

  5. I now have a Berkey, a life straw for my BOB, and have read extensively on SODIS. I have a very small pond and I have the ability to catch 1110 gallon of rain water.

  6. I have bleach, water purification tablets and think having multiple methods of purification is a must. Thanks for sharing.

  7. We use a Katadyn Gravidyn daily. Not the best water out in my neck of the woods so I’m used to filtering our tap water. Then we have 4 Lifestraws, water purification tablets and, in a pinch, bleach.

  8. I use my Hague water filter every day but have a hot water rocket, a life straw and a home made 5 gallon bucket gravity feed system witb ceramic filter as backups.

  9. I have a chemical tablets , life’s trawl water bags and always looking for more possibilities

  10. I find this very interesting and would like to win. At this time I’m using Seychelle filtration which I really like.

  11. I have a alkaline water machine but I do need electricity to run it! This item is awesome as it is transportable .

  12. Love the OPTION of solar purification! As always thank you so much for allowing me to read your blog … I find your posts to be very informative, full of humor and light-hearted fun, and very educational. Thank you. 🙂

  13. Right now we have a few purification methods- a filtering straw and iodine tablets (bleh!) are the two chief options. Letting the sun do the job sounds much better!!

  14. Don’t have a purification system yet, just a sports bottle with a filter in it. Definitely need to look into getting a good system.

  15. Nothing, to tell the truth, this is not on the list of things to think about or do. I did read an article about Alum //

  16. WOW, I never even heard of this product so even if I don’t win I will order one and if I do win then two will be in the kit.

  17. I am working with energy movement techniques and make purification/reenergizing set ups for our drinking water. I have also created an organite well topper that transforms and energizes my water to deal with our health issues. we seem to be having very good results. My husbands dementia has improved, my old dogs arthritis has improved, I live in a desert area on bentonite clay and have incredible orchard and garden. your article is very interesting

    • @Peggy – I dug into the tech sheets at the Puralytics website but did not see any indication that fluoride would be removed. I suggest a Berkey with the fluoride cartridges – I know for sure that those work.

  18. I am really trying to get a better assortment of solar preparedness items. This would be ideal for after a hurricane, when there will be lots of contaminated water.

  19. We use rain water ran through a sock filter, like those use in milking. For drinking we boil our water or let it set out in the sun in clear bottles for a few hours.

  20. Remember, one is none, two is one. Another option in case the other filters fail, tablets run out and boiling isn’t possible.

  21. Very useful item. Joins the long “I want one” list. We have water stored and tablets, but calculating up what my family of four has vs what we need for more than a month.. Oh, lacking is the word I would use. This would be a great addition to the prep boxes.

  22. At the present time, my husband and I each have a Lifestraw, as well as Coleman PA+neutralizing tablets. We have the chemical used in our hot tub, as well as Chlorox. We also have the instructions printed out to use a homemade filter using charcoal and sand.

  23. I use some filter straws and plan on setting up a system to boil water and collect the water vapor (a cooking pot with a glass lid, remove the handle, insert some small tubing in the hole and run it to another pot)

  24. We currently use a uv light plus chlorine to treat our house water as our well is considered contaminated. ( I think I should get it tested but do not know how) I also collected rain water and run it through a Britta filter pitcher when we ran out during the freezing rain/ice storm last winter until our water line thawed. I then put a light in the pump house to keep it from freezing again. I have noted on my calendar to install a new light in November for the coming winter so it wont freeze again..

  25. This bag is so brilliant.
    This is a timely article as I pulled water from our rain barrel which is green tinted. I tried 2 methods for purifying, bleach & solar – I put it in a water bottle & had it in the sun for 6 hours. It’s said that the UV rays purify. My next major purchase will be berky filters

  26. Right now I’m not doing any thing for getting good water to drink …I’m working on it as fast as I can ..

  27. I have an OLD katadyne that I am not sure still works. I would LOVE to win this novel water purifier!! I use a Brita in the house daily, and a Culligan filter that is hooked up to the water line.

  28. I consider the Katadyne Pocket Filter the best around, but I am open minded to testing others. KPF IS a bit spendy, I will readily admit. A more budget friendly option would be great, for many of us.

  29. As I have just started, I cannot afford much yet, I have the tablets and am planning to purchase a Lifestraw, am saving up for a berkey, and have tried sunlight in a clear bottle a few times,(my kids think it’s fun). I would love to have this!

  30. I have a lifestraw and tablets in BoB, but nothing aimed at larger volumes. This would be ‘very’ nice to have.

  31. We have a mini sawyer filter. This solar purifier would be a great addition to our water purification abilities.

  32. I have a life straw for spouse and myself, but been financially unable to afford anything else for water at this time. Winning this would be a GOD send.

    By the way, love your posts.

  33. This sounds amazing. It is out of my reach financially but I would love to have one. Currently I have a supply of bleach, charcoal and sand, and my rocket stove as alternative ways to filter water. Love this site.

  34. Currently not using anything – in our new-to-us house, we have now well water which tested just fine for drinking quality. I used to use a Brita water filter, but I read some not-so-good things about it.

  35. I have the life straw and have used the bleach method to sanitize water. Like post above most water supply products are out of my price range. This would be a great addition to my supplies!!
    Love your posts, free books, and all the xtra info you share with us!
    Thank you,

  36. Looks like something to put in the hunting gear stack. At the very least stash it in the 4 wheeler so it is available when out in the boonies.

  37. This is now on my wish list at Amazon. This will be a great item to have! I really appreciate the reviews of the items. It helps me decide what I want, need, or can’t use.Thank you.

    • We have a reverse osmosis system in the house, but as far as survival gear, nothing yet.

  38. At present, I have not started with water storage. I have not decided what is the best way to handle it. I do have bleach and can clean up water this way. I would be very interested in winning this purifier. Thank you for the opportunity to win.

  39. I think everyone needs a steripen, but under some situations it will not work (ie no batteries or emp) This is a great backup for that.

  40. I live in a big city and use a Big Berkey for our drinking and sometimes cooking water. And a Lifestraw in the van for emergencies.

  41. As of right now I do not have anything to purify with. I am pretty new to all of this and just beginning my prepping. This would be a great addition to my preps.

  42. We store water with a few drops of bleach. If that ran out we are fortunate to have a spring reasonable close by for drinking and a pond out back for animals. But I’d love to have this because the pond is closer and who knows how many others would use the spring.

  43. We would boil for purification. We currently use well water, so unless we don’t have a power backup, or we have to bug-out, this would be our main source. Eventually we hope to get a Berkey, though…but it’s not in the budget right now.

  44. Thanks for the contest and the article. I think water will be what most people wish they had more of. This system will come in handy. People need to think about having multiple sources of clean water.

  45. I have several Doulton cerastyl drip-type filters and powdered calcium Hypochlorite to make bleach. This bag would be a great portable addition!

  46. At the moment, the only products I have ever used to purify or filter water is a brita pitcher and a sink-attachable pur filter. I definitely notice that when using them, my tap water doesn’t taste like pond water anymore. So they do something, but their overall efficiency seems lacking for sure. Doesn’t always get out all the chlorine on the days where our water treatment guys get overzealous with the chemicals. I would absolutely love to try one of these contraptions!

  47. We have not had to purify water but would use our water purification tablets, boil it or use a soda bottle in the sun.

  48. Sounds like a great product! I like that it is easy to use and doesn’t take up much space in your pack.

  49. We currently use a two bucket system with filter and filter sock – rated for 4000 gallons of water. Does the same as a berkey, just less expensive and not as pretty. We use this on a daily basis as hubby has a sensitive tummy and can’t handle tap water or even the filtered water from the refrigerator. We also have filtered straws and purification tablets, should they be needed.

  50. We have a wage softener that back flushes our home system and my husband has a small water filter for camping – this would be great to put in our stores our use for camping/hunting!

  51. I don’t use anything for water purification but have been looking to invest as my municipality has recently started adding flouride to the water and I’m looking to detox anyway. Also, I know that having a water purification protocol is extremely important and we do go camping and hiking quite often so having something like this to bring with us would be helpful for sure!

  52. this looks like a great addition to the BOB, looks compact and easy to store. Having a couple of water purification choices with you is the smart route to take.

  53. We have some water straws, purification drops, and we store some water with small amounts of bleach in it. This SolarBag sounds like a great item to have–thanks for bringing it to our attention and giving us a chance to win one!

  54. We love all the information on survival and self-sufficiency. This water purifier would be a great addition to our slowly building tool chest.
