Just a little ventilation will help the slight smell dissipate quickly. Don't need to have an exhaust fan running, but a couple windows opened a little will clear things up pretty quickly. Exhaust fan would do it quicker, but good to be sure it goes outside and doesn't exhaust to right under the property manager's window - or possibly griping neighbors.
@VapourHaze and others above make a great point about using essential oils or other air fresheners. I'd try to go light with these, though. Strong scents (other than MJ) can sometimes cause suspicion. One that is is always plugged in or automatically mists may be better. It usually doesn't take too much at all to mask vapor. Citrus and/or lavender scents work very well, and am sure their are others. When in hotel rooms we use aromatherapy relaxation candles that have a blend of lavender, citrus and cedar. We've had friends anxious to vape stop by less than 10 minutes after vaping and be surprised we haven't started partying yet, because they smelled none!
Some vapes roast when you're not hitting, others are really only producing vapor when you're drawing on it. Some are worse roasters than others. These tend to produce a bit more smell, but nothing like smoking would.
Some vapes also come with, or have an optional aromatherapy cup. Don't think there are any vap pens that do this, but you may want to consider one for your situation. Basically you have a small glass cup that uses the same heat you vape with to heat essential oils. You can't vape and diffuse oil at the same time, but unless you are doing very long sessions a few drops of oil in one of these should clear up the smell in a matter of minutes. Lemongrass oil does very well for this in mine.
I believe the vapor smell will eventually make the room smell different. Just like vapor leaves reclaim on the vape itself, that vapor is flying into the air and invisible reclaim is sticking to everything that the vapor touches. You wouldn't notice it for a while, but eventually it would start changing the smell of things in the room, and someone might notice that it smells funky. That's why some people opt to use a smoke buddy.
Yeah, maybe, but you're talking apples and oranges here. Reclaim is created in a very small confined area and usually before you even inhale the vapor. It usually takes a good many hits just to build up in a glass stem - where hot vapor is starting to condense as soon as it moves from the heat source. Condensation is going to be pretty much done by the time you exhale, and unless you have a cool humid room isn't going to settle on things very quickly. Blow it into a space literally millions of times larger than the glass stem and with some air circulation and it will probably be pretty negligible for most. If you get 5 or 6 people vaping hours a day in a small confined space this could be an issue. But for most of us I think you would be talking years with no cleaning or regular air circulation before buildup. This can be easily tested with a piece of tissue. Put it in your vapor path before inhale and take a few hits. Notice the residue. Then, do your regular vaping and exhale through a tissue. Should be virtually nothing visible or sticky.
