What is the micron rating on this filter? Trying to read the box on line looks like says something like 'best 3 micron' can anyone answer this?

I cant remember what the certification paper said, But I think 5, But I might be wrong.

John: I do not know why numbers were not provided. I can confirm that with other premium brand of filter, KN is of low capacity. Do not think of a 1-year or 10k mile interview, half of that or less. I do not feel a efficiency difference.

According to the katadyn website, the hiker series (hiker and hiker pro) filter down to .3 microns. same as what's on the box.I know it's kept me from at least one round with crypto, after hiking with friends. I used my hiker pro, they didn't. about the time we got back to civilization they got very sick.good filter.

The factory filter bag is rated for 2 micron nominal. I am not aware of any alternate filter bags as the assembly may not be capable at proper dust/chip removal if you try to go less. The restriction at 1 micron or less may be a problem. Keeping the filter bag clean is easy enough - just tap on the sides when finished. I find the unit does a very adequate job considering the price. If finer filtration is required I would suggest an air cleaner set up with HEPA filtration.

This is an 810, a 5 micron filter element. There may be an 801, perhaps in a different pore size.

Hi, I wanted to update this info. In looking at all various pricing of these filters, I must say that the quality and price of these, are the best in what's out there!! I'd say that they're worth it!! I change mine often.. I live in dusty Arizona!

Micron is a unit of length measurement. 1 micron equals .0000393 inch. Simply put micron filtration means it prevents extremely small particles of impurities from being in your water.

The package I received does state 1 micron sediment water filter cartridge on the label. I have been using them for several months now with no complaints.

I don't know how small a micron is however I have it in my man cave and it does real well, you should also buy the carbon filter that goes on the outside of this filter. the carbon filters are usually 3 inches longer with 3 or 4 Velcro strips to hold it in place. the carbon filters do a great job and if you want better try putting 2 carbon filters on, and then you just wash the carbon filter. hope this helps.

Dear D. Lester: No, no MERV rating anywhere on the item nor on the packaging/box. Said filter is a basic, fiberglass-type of filter. BTW, I purchased one case of these filters, there was suppose to be 12 in the case (case count of 12), but the box, undamaged and unopened, only had 11 filters in it. Good luck.

I would use the 5 micron as the pre filter and the 1 micron as the post filter. This way you get the best filtration prior to filling your glass. I don't have a better answer than that because when I bought this product, I received 2 5micron filters.

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.

I don't know about micron ratings. If my mask is rated 3 microns, then I suspect it would not protect against 2.5 micron particles.

The MERV rating is a standards manufacturers use to compare the efficiency of filters. The higher the rating, the better the efficiency I picked the following information off another site "the following MERV ratings measure filtration efficiency of particles ranging from 0.3 microns and up. With more an more emphasis being placed on micro particles, 3M developed their MPR Micro Particle Rating to measure filtration of even smaller particles, down to .001. Some competitors are beginning to adopt the new standard that 3M developed but there is still predominant use of MERV. As a reference, the 3M Micro furnace filters have a MPR of 1000. Their rough equivalent MERV rating is 13-14. So while their is currently no sure equation way to convert MERV to MPR, if you use the approximate MERV rating of the Micro filter MPR rated at 1000, then the 4" filters MPR rated at 1550 would conceivably exceed MERV 18, which currently puts their filtration in line with the more expensive NordicPure furnace filters. Because 3M uses this different measuring scale and system, it's difficult to do a straight comparison."

Pierce- check out the Wynn Environmental website. They make some great aftermarket filters. I believe the one I picked up a year ago (I'm not home right now) is the 35A canister, which requires a slight fit adjustment to my (your) Delta dust collector, but it works great. I think it's 0.5 micron. Also remember that there's a trade-off between filtering capability and airflow, so the "low micron" filters require more surface area on the filter to ensure adequate airflow.Chris

Still has good micro elements! I chose the berkey because it leaves in trace minerals, but I'm no expert. There's plenty of water filtration system comparison reviews on YouTube, and most of them vouch for the berkey, especially considering what it does for the price. And the filters are good for a crazy long time.. Many years if they're properly washed and cared for. :)

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.
