Newer filters boast .1 micron filtering, while this unit is .3. It seems that a more modern, .1 micron element should be available. Is it?

Nice question. I wouldn't know that. All I know is that it works fine. No problems

This unit actually has .2 micron glassfiber filter. You can get access to the white sheets for it here: http://www.katadyn.com/usen/katadyn-products/products/katadynshopconnect/katadyn-water-filters-backcountry-series-products/katadyn-hiker-microfilter/ - This unit produces good clean water but I've only used it in mountain lakes and streams. Would I use it for water from the river behind my house in Florida? No, absolutely not. But for backpacking it is great, light, compact and easy to use.

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!

I don't know about microns, but the filter helps with allergens a lot. I live in the deep South where the pollen is very bad right now. Allergy testing revealed that I am allergic to everything tested except two items. It is wonderful to experience relief.

Pay no mind to Camelgirl--I'm a chemist, and I know why it matters. I think you'll probably have to email the manufacturer of the filters, I couldn't find it anywhere either.

you are using wrong filter replacements. make sure the filter you use for this system is dedicate for WHER25.

I only know this filter works for me. You could try it and if it doesn't work, see if you can return it.

I have a slightly different model that uses the same filter. This filter is nearly the size of the unit, so you only use one. I replace mine every few years. There is also 1" outer filter that wraps around this inner filter that is made of a soft mesh-like fabric material.

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.

Both of my filters said 5 micron molded into the top of filter. I was expecting 30 micron.

Yes. I was confused by the picture of the filter too. The AC5000 unit (black, silver control area, blue UV light tower unit) used to use 2 filters "pushed together" on top of each other, but now it seems to be a single filter and more expensive too! Yikes!Hope this helps.

I would expect the flow rate to be slightly less than an EZ-1, but I have used two of the EZ-3 filters, and both of them have been considerably slower, little more than a trickle. Most likely they filter better, but I will go back to the EZ-1 next change, if they are still available.

The Family Filter takes out more than the personal filter. But even a .02 micron filter will not take out chemicals, pesticides or heavy metals.

Culligan (not Amazon) lists this as a class 1 particulate filter - meaning between .5 and 1 micron filtration.

This particular technology is proprietary and the manufacturer doesn't give a number. In marine applications, a 10μ filter is usual for fuel-water separation.
