why the micron filter became black like carbon inside it is ok or need to replace?

The prefilter is there to catch sediment before the water passes through the carbon filters. This prevents the carbon from getting clogged up prematurely, extending the life of the unit. We recommend replacing the prefilter cartridge at least every 3 months. Actual interval will depend on your incoming water quality.

Replace the white filter when it blackens. I have to replace it about every 3 months

Carbon filter yes (lifetime) just tense and replace. Larger white (1 side) & black filter can be cleaned BUT SHOULD BE REPLACED MONTHLY... It's an awesome + extreme quiet filter pump ! Great buy from Amazon....

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

Did filter quit working or light or both? If it light you can easily replace the light. If it filter i would call manufacturer. See about getting replacement

I just installed one and the certificate was dated June 2008 and I bought it within the last year .. When I pulled the cap I heard a hiss .. so I am guessing it may be back filled with an inert gas .. Along with them being sealed in plastic and yes .. mostly carbon .. I cut one apart after 6 months of usage .. and saw nothing unusual and no mold or anything like that .. I plan on calling 3M and asking the question when I have time .. I will update this post when I get an answer.

As far as I know , the filter is mostly 'activated carbon' and porous membrane. I haven't seen anything that would indicate something coming out while in use...if you see something dark, that is just residule carbon coming out...in my opinion, this will not be harmful

I believe that is carbon residue. Before you install the filter for the very first time, rinse it thoroughly with tap water

No- make sure the filter is in correctly. That caused problems with mine too!

Not sure what you mean? Mine appears to be working as expected - still collecting dust per my black filter

MAke sure the replacement is inserted to same was as the old(gray side up) and that the small lever on the left side is not bent as the filter must make contact with the lever when re-inserting the filter- it activates an internal switch before you dial in a fan speed. If the problem still persists contact germguardian.com as they are very helpful & if its still in the one year warranty period they might offer a replacement unit (that happened to my unit)

That is carbon from the filter. It is not abnormal for it to happen, it just usually doesn't.

You may need to flush the whole filter- run the black plastic part under hot water. Or... Is the black stuff the charcoal leaking? Or is someone over feeding the fish?

I had that problem. There is a filter in line. Cleaned it and the flow was fine again.

My husband just dealt with this today. Apparently, somewhere in the back part of the filter there are some tiny holes in the plastic. They get clogged easily but it's essential they stay clear for it to work. He took a pipe cleaner and cleared them out. Now it runs fine again.

Did you give it a little time to saturate the filter? Unless you did something putting the new filter on, which I am not sure what that could be. Giving the filter time to fill is all I can think of. Good luck.

It comes with the micron filter. Not sure about the carbon... It has been a while since I purchased mine and I only used it for the micro-filtration capabilities.

I have not had any problems with my filter. I check it periodically, the usage seems correct. I'm still very pleased with I would guess the filter would be at fault. The electronics are in the filter. Gary
