As a former bee who has learned much from this sight during the past few years, I would like to extend any help that I wish was available then. I've seen a thread regarding using filtration to reduce smells. It's old and the technology I don't think was in existance for filtration at the time. I just wish I'd seen this product available in my hayday but would have no use for it as of today (personally). It would have reduced a lot of paranoia. At the big orange hardware store was found an air purifier that claims to reduce voc's. The box specifically stated toxic/non toxic voc's including (vinyl chloride, toluene & acetone). Its a carbon/hepa filtration system. The product is made by Holmes and is cost 200 clams. Per the old thread about this subject, I doubt there is any risk of explosion as this is not an ionizer. I rarely read this sight anymore but feel obligated to pitch in ideas as this sight did for me long ago.

I don't see what the problem is... Just use deodorant. No need for filters or any of that other fancy stuff. Maybe a bath now and then....

The problem is that some are defective. The defect does not become noticeable until hours later, multiplied by temperature and pressure.
One thing is for sure, they do not explode or burst (during a rxn) They just get tiny pinholes in them and the pinhole does not become obvious until the balloon is deflating (loss of HI gas) or when PI3 crystals start to react with air.
Swim theorizes that these balloons are fairly safe but unpredictable. One might get a pinhole after 5 1/2 hrs or maybe after 22 hrs of reflux and most of the time, no leaks at all. In dreams, has never had one leak when used with a condenser.
If using these balloons during a rxn and without a condenser it is always good to have excellent ventilation just in case of an unexpected pinhole.
Also if using an oil bath it is also good to use a clamp stand to keep the flask submerged.
If a balloon gets a pinhole leak, do not panic, it is not life threatening! Just adjust the clamp stand and elevate the flask (still attached) to the stand, until it is no longer submerged in the oil and allow it to come to room temperature on its own.
Yes these things do help tremendously to reduce potentially suspicious smells. At least that is what Swim said...
He said he went looking for some the other day and the stores were out of stock for the first time ever. I wonder why? Kids must really love them.
Or was scram referring to solvent boils; mainly toluene, xylene, acetone etc?

what about running the vacuum exaust/ reation opening hose down the drain and running the condenser water exaust down it too. does this work? i just moved into a bassment suite that has houses on either side that makes for a little heightened paranoia. what are the etablished methods of stink hiding, or do peepz just reccomend getting a trailer? i dunno...

Yes,this method works. The major drawback is that the water company (sewage treatment) will receive large amounts of tainted water ( and yes, they know what those contaminants are and what they mean) They can trace the contamination back to its source. there's been several busts in and around here using this method.

I'm assuming you guys are talking about the smell of the main rxn but alot of chemicals/ non polar solvents stink especially if they are being heat evapped in large trays,
if your lab is equipped with intake and outake fans as it should be your basically bringing the smell inside the lab to the outdoors if you dont live in a windy area this smell can be very noticable.
swiup knew someone that use to light incense sticks and place them in a incense holder on the floor away from all flammible stuff of course this was done with intake and outake fans , it worked well in masking smell.

Why not put an "inline" activated carbon filter in your ventilation system?

ive been looking into getting an activated C air filter for my 500W weed grow, once those babies start to get a little bigger, the smell will be a problem. the trouble is, you could expect a large decrease in the airflow, and if your putting a C filter inline with your improvised fumehood then the fumehood properties would be significantly reduced. (unless you go and buy a very expensive fan, but for that much money you might as well get a place where you dont need to worry about chemical stink...)

make a scrubber. TFSE and google will get you started. industry gets rid of "most" of the smells and their problem is a tiny bit larger than yours (ours).
follow industrial chemistry leads at the university.
just an idea (about five years old)- some couple emailed me and offered to sell me the details on a scrubber some time back - i forget which stench was the current fantasy.

SWIM's grandma was in your predicament a while ago, and she made a pair of decent sized filter boxes where the air flowed through in kind of z-formation (think two shelves inside the box on either side). The space between each shelf and the wall of the box was filled by a filter made of ground charcoal (activated charcoal would work better), wrapped in gauze and wire, for a total of four filters. The air was sucked by a 6" bathroom fan from the grow room, with a second 6" fan on the outlet of the second filter - and there was zero smell from very big plants.

You can buy the activated carbon replacement filters, get the largest cheapest brand, and rig up your own smell filter for much much cheaper.
Note: These will only work for small amounts of smellies,(great for grow rooms ect) but probably are very ineffective with such large volume contaniates like solvent vapors ect. I know that activated carbon doesn't absorb diethyl ether fumes very effectively.

I am rather sure you can use an AIR-IONIZER) i think that is what they are called. For the most effective use you would want to get a decent sized one.
Also, the unit that u use to purify the air with also give of a distinctive odour although not as noticable as the other odour trying to remove.
An air-ionizer will do the job just get a sufficent sized one, and i am sure they use carbon pads, which someone previously mentioned i thinks!
If no filter process is available your in a bit of a predicimant, shame you cant run a flu at the top of your roof like a fish n chip shop or a spray booth of a car repairer...:

I'd imagine that thing probably only works for things that constitute "dust". Not anything floating around in the air at the molecular level.

AFAIK, Negative Ions attach themselves to Positive Ions (odors) and Neutralise them.
Some reports state that they are also beneficial for plant growth and health.
In my experience, negative Ionisers are only effective at controlling odor in a small grow area and an inline activated charcoal filter is required to "odor proof" a growing area.
A negative Ioniser would be useless for controlling the smells of Chems, solvents etc.

Abolt? What? Am I missing something here? Do these things actually do more than remove dust?
Please, only persons owning this particular product, and actually tested its effectiveness in removing solvent odors respond. (bud/flower odor, other chemicals also)

Quote- "Ions are charged particles in the air that are formed in nature when enough energy acts upon a molecule such as carbon dioxide, oxygen, water, or nitrogen to eject an electron from the molecule leaving a positively charged Ion. The displaced electron attaches itself to a nearby molecule, which then becomes a negatively charged Ion. It is the negative ion of oxygen that affects us the most."

And in relation to being beneficial to plants:
"Scientists at the University of California grew barley, oats, lettuce, and peas with a total of only sixty positive ions and negative ions and found that growth was stunted and the plants were diseased. The same experiment in air with more than double the natural number of ions produced accelerated growth."
"In the 1960s one U.S. Department of Agriculture scientist grew seedlings in ion-enriched air and produced cucumbers eighteen inches longer than normal."
"Photosynthesis could not take place without ions in the atmosphere".
"In a Faraday cage, where the outside electrical fields are excluded, plants grow only about half the size they would if rooted in the garden."

I repeat, I would not recommend ionisers for the control of lab smells.

I once had a smaller negative ion generator that I purchased from the hydro store. It would zap me from time time, causing me to drop it each time.
To me it sounds like these machines are an ignition hazard, at least together with ether and other static sensitive flammables.

Swims knowledge of the ioniser is limited, although he knows that ionisers don't so much reduce the amount of stink(smell) in ones air.. but more of the amount of stink(smell) producing product.
Ionising the air reduces the amount of dirt, dust or product in the air, although it does not work with a lot of smells.. eg. Marijuana
Ozone generators are good, except for the cancer causing effects.
