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!

I am not selling anything. I purchased 2-3 6-packs of the white tabbed filters and am happy with the purchase. These are nice filters. I have purchased some thin, cheap ones in the past which were of poor quality and without any tabs.

If you have a filter that removes water born pathogens, these are not necessary. I backpack in the boundary waters, and use these instead of a filter to save weight.

Filters used for 'protection' usually cause more problems than they solve, like added lens flare and getting stuck on the lens. If the thin glass in a 'protection filter' breaks the sharp shards of broken filter glass often damage the front lens element they were intended to protect.So, IMO the best option is no filter.

Yes, I installed mine without a filter. Been running great for 10 years. Besides, I didn't think I needed a filter for boiling water.

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

No, they don't require them. I use the paper filters just because I'm used to my coffee that way.

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

No. These are strictly particulate (i.e., 'dust') filters and provide no protection from organic or inorganic vapors. Google "Selection Guide for 3M Reusable Respirators" for recommendations.

Yes. A filter is unnecessary. However, depending on whether your water source is full of minerals or organics, you might want to add a filter. I added a filter.

It is my understanding the primary reason for the filters is to enhance the taste, and it certainly does that for me, and I prefer using them. Other than that, I don't think the filters are necessary. I recommend you refer to your original manual for further clarification

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

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.

No they are not, they are made out of very thin paper, not great. Ok, If you can't find the original filters, Good luck on your quest :)

I've used it for everything with no problem. Not using a filter and no problem. Just clean out dust bin.

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?
