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 used this product all winter and never noticed a smell from the humidifier. I have allergies and I am sensitive to odors and would have been disturbed if the air had a smell. I am planning to buy this again when i run out.

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.

Very simple. Remove the used filter by sliding it off and slip the new one on. If I am going to use the humidifier immediately, I usually soak the new filter in water before putting it on. That way, the humidifier is ready to go. Be sure to fill the water reservoir with fresh clean water. If your water is particularly hard, you might want to add a softening solution, such as "Golden Solution Water treatment". This is available at Amazon.com.

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.

Hi, there actually is a small removable/washable filter (Bio Silver Stone) inside the unit. I've been very happy with this humidifier.

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.

No this humidifier does not require a filter. It should be cleaned once a week .

you should dry your nose before it makes the filter wet. it's not a good idea to make it wet, it will decrease its efficiency. I think.

Sonya P., I'm sorry and I'm not being flip, but I don't have a clue. I can't think of any way that water particles large enough to "spit" could form or even get to the impeller blades where they could be expelled into the room as "spit". I've had two of these humidifiers and have been pleasantly surprised that they have been so dry. They don't even produce a visible mist that could moisten the tiles around their base. It has taken only the simplest care to avoid even drips getting the tank to the kitchen and back for filling. Are you sure you have the Tank Cap, Filter, and Tray (names per figure on page three of instruction manual) installed properly? Sonya P., I'm sorry and I'm not being flip, but I don't have a clue.

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

Master plumber came and installed my humidifier. I asked him the same question you have for me. He said that you will go through a few more filters a year, but not substantial. He also said that that is a good thing because the dirt the filter is catching would be in your house otherwise. The reason is now that you have a higher humidity % in your house the dirt sticks better to the filter and is cleaning your household air better. I agree after one day. The air just breathes clean. Hope this helps and I am satisfied with my unit.

My humidifier has none of those problems, so you must have a defective unit. The only drawback I've experienced is when I fill the tank and put it back in the unit, and the bottom of the tank snags on the filter. I have to help the tank get into place past the filter, but everything works fine after that.

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.

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

I wouldn't want to tell you to do that since most humidifier manufacturers suggest you don't put oils of ANY kind in them. You may want to read the booklet/instruction manual that came with your particular humidifier to find out if it is safe or not per that manufacturer. Also, since these are not ESSENTIAL oils just FRAGRANCE oils there is no therapeutic benefit to reap from putting them in your humidifier, but I'm sure they would release pleasant scent just the same. I hope I've been of some help.

No you have to use the solution -or at least something similar from another brand. You can only use water for the sponge type humidifier. This guy is composed of several small gel beads that rely on the solution they sell. It looks expensive, but it's way worth it. The beads require much less service than the sponge. It took me a long time to get through my first bottle.
