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!

Dan...no, they are pre-oiled from the factory. The only oil you would need would be in the cleaning kit. It comes with oil and soap. However, no need to do that unless it's a lot of dust, etc and then maybe consider the pre-filter sock. Good luck, hope that helps.

We've never tried without filter, but it should work just fine without it. Hope this helps.

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?

Yes, they are lint free and very clean. No particles come off from these high quality filters

They do not REQUIRE the paper filters, however, you do get a very small amount of coffee "debris" in the bottom of your cup, which is so small it is not a problem for either my husband or myself. I have not tried using them for anything other than coffee. Hopefully, someone else can answer your question concerning the other items.

They don't come with filters but you should be able to use the ones in your case

No, no filter is required. However, mine came broken... I do not recommend.

Generally, the instructions for the filters will mention that something like this may happen. I do not recall this happening to us with the filters we ordered. Keep in mind that not all filters are top quality. Investigate the manufacturer before the purchase.

Yes, but you won't need them right away. The filters are effective for quite a long while are not very expensive. By the way, this is a terrific vacuum cleaner. Powerful and very quiet.

Nope. No filter required. Nothing required but water. We love ours! Works well.

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

None - you order the filters separately. There are several/many different filters depending on what your application is. Simply sawdust? Chemical fumes? Buy the filters that fit your use.

The new filters are the first ones I have purchased. I've had no issues with them.

Hi Keith, I do not use filters on my lenses. I do use the lens hoods. After 33 years as a professional photographer I find the filters a bit of a pain.
