This sponge filter does not need an air stone?

It has a built in air diffuser. Simply attach the air tube to the top of the sponge, and you're set

You need a pump and an airline but no airstone. The airline connects directly to this filter.

You need to replace the sponges IMMEDIATELY with a better filter medium. Look through the reviews and you will find what to use. Otherwise this is a great, quiet little filter for very small aquariums.

It's perfectly fine to operate with no filter. You may need to clean the foam screen on the intake pump (which disassembles for cleaning) a little more often - and even that's negligible - but using this product without a filter doesn't cause any problems. In truth, the primary function of the filter is to make the water "taste better" to your pet, much as Brita brand filter pitchers do for us humans. If you wanted to, you could even put a mesh bag with activated carbon filter media (available in aquarium supply) into the filter reservoir space, but there's really no need.

Its not really a filter because it just uses the air bubbles to lift water to the charcoal canister and out the top. The charcoal canister ideally should be below the water line to promote more water flow. Your gravel ultimately becomes a biological filter as water is pulled up the tube.

The filter is held on by the supplied suction cups. You will need to an air pump (and related tibing) to 'power' the filter. It's a good unit. I'm pleased with the results in my tank.

It seems to be OK without using any kind of filter. If 'hard' water is a problem in your area and you do not want white dust deposited in the room, buy the demineralization 'filter'.

No stones. I'm pretty sure no tubing, either. You may also need a "T" if you run it to one filter

No air pump included. You probably don't really need one, though, since the included hang-on-back filter causes plenty of surface agitation to aerate the water.

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

You don't need anything else for the filter. It has everything included. The cleaning all depends on the amount of food and fish waste. It's simple to clean , you pop it open clean the sponge and back together ready to go again. Hope this helps

Yes, you need an air pump connected to an air tube connected to this air stone. The air tube should be cut to a length that you would need to place the diffuser wherever you want it in your aquarium. It is heavy enough to stay where you place it. I use one on each side of my aquarium together with the filter and pump.

No. It is a simple water separator, but this particular model works well. A coalsesing filter is usually a bit more expensive and uses replaceable filtering elements. They are typically used in painting applications where the air absolutely MUST be clean, dry, and oil-free.

It certainly needs a filter. However, even with the filter, you will feel some air coming from the back, but not as much as when I removed the filter.

Thank you for your question! A filter is not required for this system to operate properly.

If you do a search for replacement air stones on Amazon, there are many to choose from. You can also use air stones for aquariums.

Filtered water something that won't leave calcium residues on your panasonic nano care.

It does not require filters. It does have a cloth piece that is used to collect hard water minerals, but we don't use that either. Weekly we soak the part that collects the mineral deposits in vinegar to remove the calcium. This is our second one of these humidifiers. The first one lasted ~3 years & we live in New Mexico where it is very dry and the humidifier was used many, many months of the year.
