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!

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.

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

Mine were absolutely clean and never used. I'm assuming there might be different vendors for the same product.

I apologize to you that I am unable to answer this question for you. I ordered the filters but I had someone else install it for me, so I have no idea of what you are asking me. I am so sorry! The person I had install it, had no problem at all and it works super great for me! I just cannot answer your question. I would try contacting the company and asking them.

Hello, Sorry but I do not recall ever buying these. Our POS shark died before we could buy filters. Sorry I could not help.

good to know - I wasn't sure if I had to use that filter or not. They are expensive. - cathy

The filters will last for many years. Scrub them clean with the scrubby side of a sponge on a regular basis is all you need to do. I would NOT suggest using chemical cleaners on the filters.

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.

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

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.

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.

I got them here on amazon. You'd be surprised how long the filters last. I see 10 clue st a day on average and a filter will last me a out a month.

I don't know. Our home has a complete filter system so we don't use the filter.
