will this filter stop cryptosporidium and Giardia from getting threw the straw ? and is the filter 15 microns or1.5microns

Its 15 microns and im not sure about Giardia, id like to know if you find out though.

It uses multiple newer technologies to kill and filter, not just filter like other straws do. When a competitors straw relies on just filtering the size needs to be incredibly small to make sure it blocks all the things that could kill you if ingested. The problem with that is that they are also difficult to suck water through and end up clogging up easily. We instead use both filtering technology and also technology to kill the pathogens to make sure to protect you. * 6 Stages of Filtering Including Ionic Absorption of particles to 2 Microns * Removes Chlorine, Iodine, Heavy Metals, VOC, Industrial Pollutants, Agricultural Runoff, Chemicals & Trace Pharmaceuticals * EPA Approved Iodinated Resin (Proprietary Technology) Kills Bacteria & Virus (Giardia & Cryptosporidium) There are additional test results in the listing to show how much of each of the above are killed or removed.

The 50 micron prefilter before the sediment filter is designed to catch the big stuff to increase the life of the sediment filter. The prefilter is usually washable, the sediment filter is not. So if your water is full of large particulates a 5 micron filter will plug quickly. If not it might be worth a try. The cost makes it fairly inexpensive but you have to factor in the hassle factorof replacing the sediment filter more frequently.

Sediment filters don't have GPD ratings, you're thinking of the membrane - and that's not included in this kit. The rating for the sediment filter would be in microns (the size of the particles that it will filter), and in this case it is 5 microns.

Negative, this does not filter well enough, if you have a boil advisory I would stick to boiling it. I use this as a whole house filter, and in addition I use a filter on my drinking water tap that filters down to 2 microns, this filter only does 5 microns, even if it did filter down to 2 microns, I'd still recommend boiling the water with your advisory!

It is supposed to filter Cryptosporidium. I can only say I have not had a problem. But, I do not know if the water contained this or not. I do not know where you are going to be. Higher elevation run off water seems to have less to worry about. To be safe or if you are going to be in an area that has very poor water quality, I would use the filter and a chemical treatment together. There are some very inexpensive treatment tablets that are light and will ensure that you have everything from parasites AND bacteria covered.

According to the EPA (http://www.epa.gov/mold/whattowear.html) N95 is recommended. N95 is required to filter down to 0.3 microns. According to all the googling I did, mold spores are larger than 1 micron. Please google and/or check with a mold expert on the micron size of your particular mold.

2 Microns. Not enough to filter out viruses, or even all bacteria. (Though the seller will tell you that those are killed by the iodine.)I see that the seller has changed the format of the page to be more intelligible, and now answers that question in plain sight, rather than buried in the middle of a dense text-storm like it was when I looked at it. Probably you too.

Berkey doesn't publish micron ratings as they're a little misleading. From their website, if a filter traps of 0.2 micron particles then it's acceptable - even if the other 10% lets in 1.0 micron particles - to call it a 0.2 micron filter. But if you read the test results on their website, their filters are capable of filtering 99.999% of viruses and 99.9999% of bacteria. That's better than almost any filter out there. In fact, you test the filter by adding a teaspoon of red food coloring to a gallon of water and running it through the filter. I can vouch for the fact that in mine, the water comes out crystal clear. Berkey doesn't publish micron ratings as they're a little misleading.

If it is really 15 microns then this is not even close to the ability of the lifestraw at .2 microns or other sub micron filter. There is a lot of stuff that can get through 15 microns. If you didn't get sick that just means the water wasn't biologically contaminated with something bad for you in the first place.

I believe it has to be at least 5 micron, water etc will start to pass through a 10 micron or larger to my knowledge. Water will not pass through the filter element in this funnel.

It filters any particles to 0.2microns 99.999% of all waterborne bacteria is filtered along with 99.99% of waterborne protozoan cysts.E-coli cholera salmonella cryptosporidium giardia. It was used in Haitia and being used by govt relief groups cant be used for saltwater or water treated with chemicals. doesnt remove viruses heavy metals radioactive material or anything smaller than 0.2 microns best for use in lakes or river. good for5 years unopened.

I don't believe it will! I believe it is a taste and sediment filter only! As far as I know the filtration of microbes or bacteria is beyond this filters capability!

This is just a 2 filter sediment filtration. It will take out down to 1 micro depending on what filter you put in it. A reverse osmosis will filter most everything out of the water, but it is more expensive.

The higher the Micron rating (50) the less likely you are to lose any pressure.The lower the rating (5), you may see a slight drop in pressure.But keep in mind,the lower the rating,the MORE crap is being filtered out. And you have to change filters on a regular basis,dont wait until the filter is is so covered in sludge that you cant tell that it WAS at one time,white.

My packaging envelope says 18 cm. My filter is 7 inches in diameter. The one I ordered from Amazon works really well. Good luck.

I think it can!! DE is the way to go- as it filters out the smallest particles of any filter. I would do a Google search first- there is I'm sure a chart of what size pool each filter can handle.
