Do I need to use the filter or can I run it without one?

As far as I know, you have to - though that's what kept molding on mine, which is why I no longer use it.

It is made for a filter. I went filter-less and use a Crane now. The filter just got to hard and had too much mold. Hope this helps. Also Vicks used to have this great straight filter that fit where it was supposed to but I think this uses a round one that didn't fit well at all. I am much happier with the Crane - I do pay for distilled water to make keeping the humidifier clean easier. At 75 cents a gallon it's costly but I hated dealing with filters.

The filter creates about 90 percent of the evaporation so it will still work a little, but your best bet is to get a filter and run it intermittently on a timer to preserve your filter life...

Yes - you definitely need the filter. They can be cleaned, or a new one can be purchased from Amazon for $11. I'm happy with the unit; haven't had any leaks since I sealed the gasket with Vaseline and ensure that it is closed tightly.

No. You can use between 1 and 3 filters. The more filters you have, the faster it will filter. 1 filter ~ 14 hours. 2 filters ~ 8 hours. 3 filters ~ 5 hours.

Dunno. Don't have one. This is not a great filter....returned due to scratches right out of the box...

I never used the filter and I only imagine it is of use if you are in a hard water area. It worked fine without it.

I have a slightly different model that uses the same filter. This filter is nearly the size of the unit, so you only use one. I replace mine every few years. There is also 1" outer filter that wraps around this inner filter that is made of a soft mesh-like fabric material.

You'll need to but an air pump to drive this filter. I always get a pump at least one step up from the aquarium size I am setting up. You'll also need an air hose to connect the 2.

No I purchased a separate inline filter for it, the unit is great better than one we purchased through our R/O vendor.

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

You most likely will need a filtering box to make it work. That is what I am using and it works great!

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

There are no filters necessary, but you will need to take it apart to clean it occasionally as you will get mineral build up around the heater and on the plastic.

It does come with one filter. They are not required, but do help with operation when used.

I actually don't use the filter. I used the one it gave me, but it only lasted a month or so, then I tossed it. The waterer works fine without it.

No it does not need a filter. Pretty simple machine we use daily and my son loves it.

I have not needed a filter and I use only 20lb tanks. Just use the provided hose and it'll be fine.

No, you don't NEED IT but you get a little fine grounds without it. Can't see wasting the money of filters....
