No Filter: So Is It Safe? So are these, without filters, safe?

Yes, they are safe without filters, filters are not needed for that reason in ultrasonic humidifiers. Why you should be using filtered or distilled water anyway is because of the DEPOSITS that collect on the ultrasonic disk at the bottom (heart?) of the unit. When too much mineral deposit forms on the disk, it will stop working. That's also why you sometimes get a little brush with this type of humidifiers, but those are not very effective I've found: I have lost two units to this before I figured out the problem with the deposits. Now I use either boiled and cooled water, or filtered water. Knock on wood, that has kept it running for many winters!

From what I understand they are really meant for eyeglasses, not coated lenses and filters. I would say "Use at your own risk".

Yes this unit truly works without filters. Just the normal cleaning with white vinegar and occasional diinfecting with clorox, it is a great product.

Depends on how dusty the conditions are.It's best to clean them after each use.Order washable filters from Amazon and be done with it.

I would say yes BUT you should wash them out and only use them maybe 1 or 2 time more and then just buy filters. Try one out and see.

I have washed them in water. They seem to work afterwards. I would reccomend allowing them to dry completely before you use them after a wash. What works better and faster then washing them is to take them outside and spray them with a can of compressed air you use on electronics to remove the dust. This works better and they can be used right after. Note that should you choose to was them you run the risk of mold or mildew within the filter if they do not dry properly.

I just learned from my wife that Meijer does have a filter now. Haven't tried them though so don't know how good they might be. We have always used the manufacturer filters and they work just fine.

I do not know if these filters are intended to be washable, but I doubt it. Package insert makes no mention of washing filters. I also doubt filters would be effective after washing.

Yes, they are very easy to clean. Just brush off as directed in package insert. Next time I'm going to order the 7" ones though. The 9" ones are too big for my filter. The extra 2" just sit there in the air inside the filter, not filtering anything. Hope this helps.

You would have to ask the manufacturer of the filters for that info.....I'm just a consumer :)

on the manufacturer's website, you should not have to replace the filters. They are washable as far as I have found.

Filters came with mine although I know that at least one reviewer said theirs came without. Maybe it depends on which seller you buy from?

There is no filter. Typically you would be using bottled water and no filter would be needed.

Yes. You do need to clean the filters. However, I did not read that until the third filter. When I tried to clean it saw what was going into my body and stuck on my fingers with a horrible smell, I decided right then to finish up with this cycle and move onto a smoke free life. Today has been three months and ten days.

Sorry I can't help, I never use them, I have indirect lighting in the rooms I use my monitors in.Good luck, I know there are some nice filters out there, co-workers of mine have had them in the past.
