Are the lids air-tight ?

Not 100% airtight but very closely sealed. I keep my coffee and sugar in each and they stay fresh - no problem.

The canisters are most definitely airtight. They have a rubber gasket on the top that seals against the ceramic lip of the bottom. You can feel and hear the seal breaking whenever you lift the lid. You have to actually PULL the lids off--because of the seal.

I have not had any problems - would say they are both air tight/liquid tight - if not for storage problems in a small kitchen I would love to have a second set.

They are not air tight - liquids seep out if you turn them on the side. I use them in the frig and for pantry storage but have never used them in the freezer.

I don't believe it is airtight. The lid has a silicone gasket that slides up and down when you open and close, so I don't see how it could be airtight. I agree with the second answer, it is tight but not air tight.

Yes, they are airtight. I shake liquids around in them all the time. These lids aren't for canning purposes, though.

Theyl're not as tight as the metal lids. I like them because I can label the lids with dry erase markers.

They are not airtight. Water will not get in. There is no seal, but the lid overlaps the side by 2 inches. The lid also fits very snug. I have used these for about 5 years now. They are very well made (good materials, heavy duty) hold up to lots of abuse and have a lot of space. I put gear I want to keep dry and safe in it and put it in the bed of my truck. I have traveled many thousand miles with these in my truck bed and never had any issues with water leakage no matter what the weather brings.

While the lid has a snug fit I would not consider it air tight. Depending on what you are storing my answer would be different... cookie dough yes... air sensitive fruits no....

They aren't air tight, but I've placed them in my fridge before without any issues.

I haven't tried to use them in this manner but, to be honest, I think that would be asking for trouble. These lids are tight, but not bulletproof. You should probably try to find something where the lid screws on tightly, rather than pushes down to form a seal. My opinion only.

The jars are glass and the tops are plastic. I would not say they are as airtight as glass and metal would be. Suggest your get small mason jars as their lids have metal inserts with a rubber seal. Cheaper too.

There is a rubber seal on the inside of the plastic lid. Some of them still leak. I certainly would not call them airtight.

Ummm....I think they are supposed to be. One of the lids has vents on it. I stopped using them pretty quickly since they won't stick to anything!

Yes the lids seem airtight to me. They have screw on grooves that secure on pretty well. Interesting idea to use them for dry snacks. Will have to try.

Yes, they are. However, I still sealed everything up with a mylar bag before putting on the lid. They are very high quality buckets/lids that seal up very tight and once sealed, have a one time use pull strip to open them again. The lids will go on again without the pull strip...but I wouldn't think it would be air tight without that strip.

Yes they are. I love these lids. They are so easy to open and keeps the food so fresh.
