Fermentation chamber smell, should it be vented?

[bf514921]

Making an oktoberfest lager, and i built a lagering chamber out of a 10 cubic foot chest freezer. Its not airtight but it definately doesn't let much air in or out. When i open the frezzer to check fermentation, there is one hell of a strong smell i assume from the fermentation.
1. Is letting that smell concentrait bad?
2. should i occationaly open and let it out? it this bad to have around the carboy for fermentation.
3. or am i huffing some concentrated carboy airlock activity.

sulpher smell? a filter can be made that attaches to your airlock that will scrub most odors. I use it every time i make kolsch, or any other brew that calls for heavy sulfer odor(most lagers) this way swmbo has no reason to yell at me.

yeah sulpher smell would be close to what i smell, and it is a lager, of course i am a little late already on the swmbo telling me it stinks, would you have link to the kind of filter you use
