Water Filters
This is an education page; not a page to sell you a particular filter from a particular company.
There's much to selecting the proper filter and it starts with knowing what you need and what 
is available  so you can know better what to choose. I've learned a lot about water filters in the
last few years and I would like to share this knowledge with you.

See more water filters and much more information at our other website  

See http://www.waterfilterlabs.com/Introduction-gravity-water-filter-heavy-metals-lab-results.html 
for a complete testing report on which filters that are on the market today provide the best test 
results. Mike Adams from the Health Ranger has done the testing and homework for us. Visit his 
site above to read the results. From his testing, the Berkey Filter below would be hard to improve 

For gravity systems

See the Berkey line of .025 micron gravity filters at  www.potspansandfilters.com/berkey.htm 
Berkey purifiers provide incredibly clean, pure, sparkling water whether the source is a wild 
stream, stagnant pond, lake, private well, or substandard municipal supply. Available in a wide 
range of sizes, Berkey purifiers rely on no moving parts and use no electricity.  Berkey filters 
are gravity filters only.  They are designed with two chambers; an upper chamber that contains 
the filter(s) which you put the water that needs to be cleaned up into, and a lower chamber that 
filtered water flows into by gravity. These filters are not meant for connection to pressurized 
water systems. The same technology and gravity flow filter is used in each Berkey model. 
Size, number of filters used, capacity and flowrate  is the only difference among models.
The Berkey black filter was developed to go beyond what the ceramic Doulton was capable 
of as more and more contaminants entered our water supply. The newer black filter not only 
removes protozoa and bacteria but at .025 microns, also removes chemicals, viruses, heavy 
metals, fertilizers and a long list of additional contaminants from your drinking water including 
many pharmaceutical drugs people flush down the sink, flouride, chlorine and  and chloramines. 
Go to here for a six page list of all the contaminants the Berkey black filter is capable of removing. 
Black Berkey purification elements significantly raised the bar to a level that no other gravity 
flow water filters are currently able to attain.

For pressurized systems
The Doulton 4 stage carbon block silver impregnated ceramic coated filter cartridge found in the Belkraft
water filter lineup is a Doulton custom made cartridge for Belkraft considered full spectrum, the best they
make. Belkraft filters; slimline, universal,big blue, whole house, etc are for pressurized water systems. They
tie right in to your household systems. They work until you have no water pressure. Then it pays to have a
gravity feed backup system also. Both systems have their own advantages.

Here is a new inexpensive LifeStraw Family water purifier filter being used in Africa that filters out viruses too 
and is good for 18,000 liters, 3 years worth for a family of 5.

When choosing a water filter to ensure you always have good drinking water,  understand what 
you are trying to filter for when researching and choosing water filtration. Then factor in size of 
container you will be packing. Filters only like the water filter straw and Sawyer SP128 are light 
to carry but if you get thirsty between streams you have no stored water to drink. The small storage 
bottle types might be a better bet.

We need to filter for bacteria which range in size from .2 to 5 microns, such as e-coli, salmonella, 
and cholera.  We need to filter for protozoa such as  amoebas, giardia lamblia, and cryptosporidium 
which range in size from 1-15 microns in size which is pretty easy to do. And we may need to filter out 
viruses like hepatitis, norwalk, parvo and polio viruses which range in size from .02 microns to .20 
microns and larger if you are visiting foreign countries and this is where the cheaper filters don't cut it 
and if you want to get this job done you have to dig deeper into your pocketbook. 

A micron is a millionth of a meter. A micron is 10-
6 (ten to the minus 6th meters). A nanometer is a 
billionth of a meter, (ten to the minus 9th meters).  As some filters have specs in nanos instead of microns, you need to know the conversion. 200 nanometers is equivalent to .2 microns. The smallest 
virus is the polio and parvo viruses at about 20-25 nanometers or .02 to .025 microns. So if you want to 
catch these you have purchase a filter capable of .02 microns or smaller; or a filter such as the 
Seychelle water straw that says they can do this using an iodine impregnated ceramic, a  different mechanism besides entrapment.

Is such capability as .02 microns necessary? According to some anything less than .1 is overkill and  
.02 is not needed in the US but only in third world countries.  In North America we supposedly 
do not have concerns about viruses in our water; at least lake and river water.  They simply cannot 
survive. Viruses derive from contaminated human sewage and die shortly after entering a body o

water. In Third World countries outbreaks have occurred due to poor treatment of sewage
; where they drink water that is contaminated with urine and feces. Sewage without viruses can be handled 
a good .1micron  filter. The only viruses with the potential to survive in water are hepatitis (which 
is rare) and Polio (which is extremely rare). Sawyer filters confirms this.

Lifesaver 4000
The  filter with the capability  to capture less than .02 microns is the LifeSaver 4000 or 6000 
which has a filter capability as low as .015 microns (15 nanometers).  This can be found on the 
net at around $147 , although it lists for much higher.  They have a larger filter model in the same 
sized bottle called the 6000  good for 6000 liters instead of 4000 liters before you have to change 
the main filter. And it's not that much more in price. Both need the carbon filter changed every 250 
liters but the carbon filter is only about $10. It's about 3.5" in diameter by a little over 12" long. I 
like the pump mechanism in these to get the waater out of the bottle. 
The company site is at http://www.lifesaversystems.com/water-purification-systems . They also 
make a 5 gal jerrycan version for larger applications you can get for as low as $365. Actually there's 
a 10,000 litre, 20,000and 40,000 liter model for higher useage rates; they all hold 18.5 liters. Just 
like the handheld 4000 model you fill the container with bad water, use the hand pump to put a little pressure in it and it forces the water out through the filter and into your glass or pitcher.  This jerrycan 
setup is being used by many African villages where they simply do not have a clean pure source of drinking water and malaria runs rampant without such a device. The jerrycans also have a .015 
micron filter in them, just much larger than the bottles.

The LIFESAVER® 4000 Ultra Filtration Water Bottle uses a highly advanced ultra-filtration 
system to remove bacteria, viruses, cysts, parasites, fungi and all other microbiological waterborne pathogens. It has replaceable filters which can treat up to 4,000 liters of water at a rate of 750ml 
in just under a minute without using chemicals or leaving a chemical taste. All bottles include a 
pre-filter disc, a carbon filter and a chew-proof nozzle. Two-year manufacturer’s limited warranty.
The carbon filter needs to be changed about every 105 gallons but it costs less than $10 each. 
The foam prefilter disc is cheap also and needs to be changed when you wear it out. LIFESAVER technology filters down to 15 nanometres, that is 0.015microns. They are the world's first and only 
portable technology that is patented worldwide, to filter down to this level. With the smallest virus 
known being Polio at 25 nanometers, you are safe in the knowledge that LIFESAVER filters all 
bacteria, viruses, cysts and all waterborne pathogens from your water.



$147 good for 4000 liters of water , replacement filters $129, replace carbon filter every 250 L 
about $30/ 4 filters  The foam prefilters are about $8 each

FAILSAFE Technology

All LIFESAVER products operate FAILSAFE technology. As the LIFESAVER product approaches the end of ifs filtration capacity, it will require a greater number of pumps to induce water flow. When no more water can be induced to flow despite pumping, the cartridge has expired and needs replacing.

LIFESAVER Technology

The LIFESAVER technology is the world's first and only portable technology that removes all bacteria, viruses, cysts, parasites, fungi and all other microbiological waterborne pathogens without the aid of any foul tasting chemicals like iodine or chlorine or the need for any power or UV light.

Activated Carbon

The LIFESAVER activated carbon filters are made of high specification activated carbon block which reduces a broad spectrum of chemical residues including pesticides, endocrine, disrupting compounds, medical residues and heavy metals such as lead and copper. It also eliminates bad tastes and odours from contaminates such as chlorine and sulphur. Each LIFESAVER jerrycan activated carbon lasts 250L of water.

LIFESAVER Regulations

LIFESAVER systems ltd complies with all British, US and European Drinking Water Regulations for Microbiological Reduction as tested and certified by the London School of Hygiene and Tropical Medicine.

The Science behind LIFESAVER

LIFESAVER technology filters down to 15 nanometres, that is 0.015microns. We are the world's first and only portable technology that is patented worldwide, to filter down to this level. With the smallest virus known being Polio at 25 nanometers, you are safe in the knowledge that LIFESAVER filters all bacteria, viruses, cysts and all waterborne pathogens from your water.

Sawyer SP128  .1 micron mini filter
The Sawyer Mini is ideal for outdoor recreation, hiking, camping, scouting, domestic and 
international travel, and emergency preparedness. This high performance Mini filter fits in 
the palm of your hand, weighs 2 ounces, is cheap ~ $20 - $24, and filters up to 100,000 
gallons (30 times more than comparable filters). When flow slows down simply backflush the 
filter. Put the drinking end in the faucet and blow all the filtered stuff back out the normal intake 
It attaches to the included drinking pouch, standard disposable water bottles, hydration packs, 
or use the plastic straw to drink through the filter directly  from your water source. Flows well 
and can provide up to 500 gallons/day. Withstands up to  70 psi before you can damage the 
filter. Comes as a four pack for about $100 also. A great thing to take with you on vacations to 
foreign countries when you are not sure what's in the glass of water the waiter just put on your 
table or you need a drink out of the hotel faucet. At .1 micron it does not cover the smallest 
viruses but does cover bacteria and all protozoa. Viruses are not a problem in American rivers 
and lakes.    Watch the video for the many ways you can use it.


We are pushing ThriveLife to carry this filter as it is very economical and covers a lot of 
situations at very minimal cost. Keep one in your bugout bag, automobile, backpack, etc. 

Sawyer Model SP-190 (or SP 191 with faucet adaptor) .02 micron for virus protection
ThriveLife part #52570, ~ $145

Sawyer does make a .02 filter (model SP 190 )  to cover all viruses but it costs 
more and is only needed in third world countries where people defecate and urinate in the 
water they eventually drink and viruses live in that kind of environment. But lakes and rivers 
here in America would rarely harbor such a virus.
But  the .02  has plenty of flow (170 gal/day) also and could provide potable water from 
lakes and ponds where beaver, bear, moose, deer  and elk habitat. Or shallow wells which 
might have some unknowns floating around. A great thing to take with you on vacations to 
foreign countries when you are not sure what's in the glass of water the waiter just put on 
your table or you need a drink out of the hotel faucet. And again, when flowrate lessens, 
simply backflush the filter to clean it out .

This small, lightweight filter kit can provide up to 170 gallons of clean water per day for over 
16 years. This filter has a Manufacturer's 1 million gallon guarantee. That is over 18,000 55 
gallon water barrels, and 1 1/2 Olympic size swimming pools. This truly is a filter for life. 
Assembly kit includes hole cutter, Sawyer Point ZeroTWO™ 0.02 Micron Absolute Inline 
Water Purifier, adapter, hose, filter cleaner, filter hanger, and detailed instruction book. 
Bucket not included. The Sawyer Point ZeroTWO™ Viral Water Purifier offers the same 
level of protection against bacteria and protozoa, and is the first portable filtration device 
to remove viruses mechanically. It does so at a 0.02 Micron Absolute 5.5 log (99.9997%) 
removal rate, the highest level of filtration available today.
See video at http://www.thrivelife.com/sawyer-point-two-bucket-filter.html 

Sawyer water bottle filter
.1 micron filter, just dip the bottle in the lake or river, screw the lid on and drink.
Item SP140
At just 5.5 ounces in weight, this durable BPA FREE water bottle can deliver clean water as 
fast as you can drink it. Use with the bottle, on a hydration pack, or as an ultra light. Kit includes: 
34 oz BPA FREE Durable Water Bottle with a flip-top cap, Sawyer PointONE™ 0.10 Absolute 
Micron Water Filter, 2 Replacement Drinking Straws, One Cleaning Syringe, Cleaning and

How to make your own .2 micron water filter for less than $30
At .2 microns you will cover all the
bacteria which range in size from .2 to 5 microns, such as 
e-coli, salmonella, and cholera.  We need to filter for protozoa such as  amoebas, giardia lamblia, 
and cryptosporidium which range in size from 1-15 microns in size which is pretty easy to do.
Remember in the USA waterborne viruses are not considered a problem unless you are trying
to clean up sewage water. 

There's only 4 things needed in this set up
Two 5 gallon plastic pails you can get new from Lowes or Home Depot for about $4 each.

One Tomlinson water crock replacement spigot faucet dispenser 
less than $7 on ebay. 

One .2 micron Zen ceramic dome replacement filter 
This is cleanable with a scotchbrite pad. $14 - $20 on ebay.


- you can buy the complete Zen filter setup on ebay for about $150 but you really 
only need the filter part of it which costs $14 - $20 on ebay.
there are many ceramic filters you can find on ebay besides the Zen replacement filter but 
at .2 microns and it's cleanable using a scotchbrite pad,  and has a low profile , the Zen 
replacement  is inexpensive and will work just fine. Candle filters at .05 microns work good 
too but they are around $30
and don't have the low profile.

Instructions to assemble
Bucket 1 is on bottom, bucket 2 is on top
In bucket 1 drill a round 3/4" hole in the side of the bucket about 1 1/2" up from the bottom
in which to mount the spigot which you will open to put water into a glass or pitcher as the bottom 
bucket, bucket #1 will contain the clean potable water. In the lid of bucket 1 drill a 3/8" hole that 
the nipple from the ceramic filter can fit into. That hole can even be a little larger
to line up easier.

In bucket 2, the top bucket, drill a 3/8" hole in the center of the bottom of the bucket. You may 
want to drill this hole first, then set bucket 2 on top of bucket 1, center it, and then mark the hole 
in the lid on bucket 1.
These 3/8" holes have to line up so when bucket 2 sits on top of the lid of bucket 1, bucket 2 is 
centered over bucket 1 so the nipple from the ceramic filter goes inside the lid hole of bucket 1 
just a little ways so the water being filtered goes into bucket 1.

Install the ceramic filter into the bottom of bucket 2, using the rubber washer to ensure a water 
tight seal as the only water we want going into bucket 1 from bucket 2 has to pass through the 
ceramic filter. When the filter is installed into bucket 2, and the plastic nut tightened against the 
rubber washer there will be part of a threaded nipple left at the bottom of bucket 2. This nipple 
is what is inserted into the 3/8" hole you drilled into the lid of bucket 1. 

You are done. 

Now pour the contaminated water into the top bucket, bucket 2, and it will filter through the 
ceramic filter into bucket 1 below where you can remove it to drink via the spigot on the side 
near the bottom of the bucket. Clean the ceramic filter with a scotchbrite pad when flowrate 
starts slowing down.  Simple, effective, inexpensive.
