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!

You can buy a filter for it, but it is not required to make it work. I use distilled water in mine and there is no danger.

I have the green one and it does have a filter. thought the price reasonable. I do have a complaint. Most of the time not a lot of mist comes out even on High. Only occasionally does it actually look like a High amount of mist is coming out. It hasn't really helped the dryness so unsure if it's working properly. This doesn't really address your question but thought you'd like to know.

Once you install the filter. Fill the tank with water. sit tank on humidifier and turn the knob to desired mist level. (do all the above with humidifier unplugged) It's an excellent product. I have gone through several and this one does the job. Hope I have been helpful

Hi Joe,No need to use the humidifier that came with your humidor if you are using DryMistat tube/s.Enjoy!

No - the humidifier does not take filters, and the tank is mold and mildew resistant. I've been using the older model for a year, and haven't had any trouble with bacteria/mold.

I just looked it up on the Crane website and this is whta it said "All of our humidifiers are made with the following plastics: ABS, SAN, and PP. The chemicals Bishenol A and Phthalate are not used in the manufacturing process." sounds to me like it may be worded JUST right to get them out of saying yes it does. "not used in manufacturing process" tips you off that its not garenteed they are not used. LOl

For humidifiers with a heating element, I recommend using distilled water, which will prevent any build-up of stuff (calcium, minerals, etc) on the heating element. If not, you'll have to constantly be soaking the heating chamber in vinegar.

The filters are extremely important. I bought one of these filterless ones and the calcified elements in the water spray out into the air and put a cement sludge on everything. I got a scratchy throat, my dry eye syndrome got worse, and then this sludge showed up on my TV and my furniture. Always go for the filtered humidifiers for your health.

Yes, unless your humidifier specically says not to add any chemicals to the water. Also, when I used the Best Air treatment, it still produced white dust.

The only thing you can do is keep it clean with the cleaner they sell. Outside of that, if it quits misting, there's usually not much you can do or replace yourself! Kinda sucks because I know they fail for no good reason, but it's my favorite humidifier when it works! You may try reseating the water container into the base unit and or jarring it a little bit to see if something is stuck. I wouldn't attempt to dis-assemble it. Messing with water and electricity is dangerous.

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.

yes, you can use the cool mist humidifier without the filter cartridge but I suggest you use distilled water, no problem

Yes, it works without the cartridge, but I did notice that there was more mineral "dust" than with the cartridge. I use my Vornado 24/7 and as of today, am still using the same mineral cartridge after a bit over a month. I did order replacements, but am going to hold off on using them until I notice the mineral "dust" again. Then I think its time for a new cartridge. Hoping to get about 6 weeks out of a cartridge. Definitely the best humidifier I have used.

Nothing but water recommended by the manufacturer. It is a great humidifier and I would advise against ruining it with a fragrance. Good smelling odors can turn foul in humidifiers and once in the filters difficult to get out.

I just emailed the company and they said to change every two months with this IMPORTANT NOTE: Since you are dealing with water, it is very easy, and extremely common to end up with a moldy filter if it is not taken care of. Whenever you turn your humidifier off you should remove the filter. Never let the filter sit inside the wet unit while it is off.

No this does not require a filter. Humidifiers without filters have an option for a filter (ball) in the reservoir/tank, but it's definitely not required for normal operation

I am sure it is safe to use on a humidifier since it is safe for food equipment. However there maybe a more effective cheaper descaling product out there since any residue left does not have to be food safe.
