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.

There is no filter in SU-2020 Humidifier. The one that has a filter is SU-4010 or SU-4010G. Thanks.

I didn't use mine long enough to need a filter change. But from experience with other humidifiers, you should change the filter when it becomes discolored. The filter is you wick for moving the water to the top. When you notice a change in the amount of steam, the wick is no longer effective.

No. You only use salt with a warm air vaporizer if you have the kind of water that doesn't produce much steam on its own. You don't use salt with a cool mist humidifier, ever. I have two of these small personal cool air humidifiers and find them very useful for small rooms, or to use next to the bed while you sleep.

Whatever place you put it, be sure it is secure. It should also complement air flow for dust collection and heat or ac sources? My concern is also access to changing the filters as they clog? It's an odd size filter. I'm considering making a pre filter frame to use cheaper filters from the box store. Good luck, be safe!

It isn't a manufacturer-specific product, so while I can't say for sure, I do not see why it would be a problem. Most humidifiers are built fairly similarly.

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.

It doesn't "purify" the air in the usual sense of processing it internally via a filter to remove impurities. It's probably marketing-speak for "humid air is good for you". All it does is produce a fine mist with all the benefits of such action. For all I know this could have some sort of a minor "purifying" effect (maybe large particles can be trapped by droplets and fall to the ground?) but if you're looking for an air purifier per se, there is probably a better choice than this.

I use in my Vick's cool mist humidifier that is filterless. I drop in the water tank. No problem with dropping in or removing to change.Can always call the manufacturer to check too.

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.

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.

I have not tried to-when the cartridge gets old I see a rusty accumulation of deposits on my humidifier so I would guess the answer is you definitely do need it.

According to the directions in the instruction booklet, you must not use any drops or anything other than clean water in the humidifier. You also must not stick something in the opening where the mist comes out.

Reading about humidifiers, ultrasonic humidifiers put quite a bit of white dust into the air. You would have to have naturally very soft water. NOT water softener water. Or use distilled water. Very expensive.

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 Satechi ones DO NOT WORk! I thought they might and they are too thin and have a hard plastic case. I found a web site for the humidifier and will be emailing them to see if they have replacements. The product comes with 2 filters and us und distilled water I haven't had to replace yet.

No filter(s). You have the inhaler and the salts. The dust from the salt is okay for most people (unless you have an allergy, but I have not heard of that before). All the best!
