We are getting white dust everywhere. One reviewer stated they had to replace a calcium filter?

This is what the manufacturer says on their FAQ's about the white dust:Why is there white dust on my furniture?If water is especially hard or has a high mineral content, you may notice white dust around the unit. White dust is not a problem it is from the minerals in the water that form the dust. The humidifier evaporates the water and then the white dust is left in the unit, not sent out into the air. If bothersome, use distilled water or you can purchase one of our Decalcification Filters (FLTDC) to help with the problem.I personally do not have this issue.

Depends on how hard you water is. Just with filtered water from my sink I get almost nothing. disteled water would be the best.

Jeff, I would have to say no, because I never saw any. After reading all the other answers - I still say no, and I use water right out of the tap. The one at the apartment is city water, but one at the house is drilled well water and neither of these humidifiers leave white dust.

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

I have the same issue and that is why I like the filter system. I follow the recommendation to clean with a combination of white vinegar and water. I do need to rinse this through more often and do not wait for the clean light to come on. Happy trails

No, no white dust of any kind. The white dust is usually a problem with ultrasonic humidifiers. This one is an evaporative type, where all hard particles in the water sink to the bottom.

Yes! I had to quit using it as EVERYTHING was sticky coated w/calcium deposits. Post asking now if there is a 'demineralizing' filter that can be put in tank.

No this is not common. I have had my Venta humidifier for 4 months and replaced the cartridge once and have not had any issues or white dust. I would contact customer support. Good luck.

I have the same problem, and it usually does this while I have the unit running for more then a day straight. I think it is some kind of vibration from the motor and the plastic. I'm not too happy with this filter after having it for three months. My allergies seem worse then ever, and I've replaced the prefilter and have vacuumed the HEPA filter.

Mine does this too! It's contaminating my fish tank. I also get carbon dust, even though I've rinsed, and re-rinsed the filters. The carbon dust accumulates on the leaves of my plants.

Sorry I just took out filter and wiped it. Did you call company. I was surprised it wasn't dirtier because I think that the dog hair around room is so much better since I got purifier.

Sand is either to high in the filter, to much sand, or the tube inside the filter isnt seated correctly or possibly damaged. But it needs to be in the filter possision

I have not changed the filter in my units yet. I have cleaned them, meaning I have knocked the dust off them. But I have not replaced them. There is a small somewhat fragile one in there that you want to be careful with as I guess there is no replacement. The other is larger, maybe paper although I don't remember for sure. This is the one I have knocked the dust off.

I didn't like this unit as the "silver" filter did not remotely filter out the minerals so there is a super fine dust that gets everywhere. For example, It got inside the display screens of my AV receiver (between the front glass and the digital led display) - it's impossible to get this dust out. The marketing/advertising says there is no mineral dust because of the filter, but that simply isn't true. And I had 2 different units because of a return and they both did it. I regularly cleaned the unit and still had the issue. Not to mention some of the metal parts that sit in the water rusted super quick (within 3 months of having the unit). So, poorly marketed and poorly designed. Stay away!! I didn't like this unit as the "silver" filter did not remotely filter out the minerals so there is a super fine dust that gets everywhere.

We live in LA where the water had a lot of larger debris that clogged the filter after just 2 months, so sounds like you are starting with water that is clean, at least on a macro level! To clean it we simply used the scrubby side of a kitchen sponge - no soap - until it was white again. This restored the water flow quite nicely.

What may appear as white dust may be from the water source that has dried. The water in the area that I had to use in the unit also left a similar residue, but it is not harmful. It has to do with the area having hard water and me not choosing to use distilled water for the unit. If you are extremely concerned and financially capable, you may choose to try distilled water, change your filter, run bleach through the system and see if the effect is still noticed.

Sorry, I can't help with this. I returned the item due to poor performance and didn't have it long enough to have to clean the filter. Good luck.

I've only had mine for 2months..I'm not sure,but other reviewers have said they have vacuumed or lightly brushed the filter to clean.
