What do you think is the best way to remove smoke from a room. I have a smoker in the house that we are going to contain to one room and I was wondering what is the best way to clean the air in that room. My options are either to install an exhaust fan or put an air filter(a good one). There are pros and cons of each that I would like to way in. For instance an exhaust fan will be removing indoor air and replacing it with outside air and that probably will run up the heating and cooling while it doesn't have any filters to replace like the air filter. I don't know if this is true or not but smoke is probably heavier than the surrounding air and that would be better for an air filter because the smoke can be filter out from the floor better because the air filter sits on the floor while the exhaust fan is in the ceiling. What would you gyes do if you where in my shoes :confused: . Thanks

Hi,
I really hope this doesn't sound dumb, but what kind of "smoker" are you referring to. Like a bar-b-q smoker? Or some who smokes cigarettes?
If it's a bar-b-q smoker, are you sure you want to put it in the house? The smell is really hard to get rid of.
One good way would be to put a small exhaust fan in the wall, venting to outside, just above the "smoker". That would pull out most of the smoke as you are cooking, but would also pull some of the heat out, too.
You might be able to get out some of the smell and smoke with a Whirlpool Air Purifier, but a good one is around $250. There are other good brands also.
Another idea is to put a "vent hood" over the smoker, such as like a stove top vent. Then, vent the small fan outside. The hood would catch most of the smoke, but the smoker would have to be sitting directly under the hood.
Maybe some others here will have some ideas also. Happy New Year!

Hi fred,

I should've stated more clearer but it is a person smoking cigarettes. Thanks for the reply and happy new years to you too. Thanks:D

The exhaust fan would be expensive to rehear the air. There are air to air heat exchangers that would save some of the heat. I am afraid mast ordinary air filters wouldn't take the smoke out. Might try the electrostatic ones in the furnace. I saw banner add for them above this thread. Somebody is paying to keep AMHD on the net, and I expect it is the advertisers.

Thanks a whole lot. I really do appreciate it. . Lets say if the air filter is equipped with a carbon filter. I really forgot to mention that on my beginning post. This should take out carbon monoxide right. To get a really good portable filter with a hepa filter and carbon filter attached to it and set it in that single room would be nice sense they don't throw out your already heated air but they cost so much initially and changing those filters when they go bad can add a lot of $. This is in a room that has no return ducts also. I could just simply cut a hole in the ceiling and vent the air in the space that is between the ceiling and the roof with an exhaust fan. That might just be the simplest and cheapest method. The room doesn't have any walls that are outside walls. Honestly, the smoker has to be contained in that room because a baby is coming in the house. He's quite stubborn when it comes to his smoking and just to get the guy to smoke only in that room was quite a challenge. Anything that you or anybody can add to this would be VERY very helpful. OH yah he smokes about half to a full pack a day. Thanks again

Do you have a reliable source for the idea that activated carbon removes carbon monoxide? I am not sure it does. On the other hand, how much can a half a pack a day produce? The CO problem wouldn't be any worse with a filter that didn't remove it than with no filter at all. I vote for a room filter.

If you do vent into the attic, I would run the vent up near one of the roof vents hoping the warm, moist air from the house will go out it rather than condense and create moisture problems. Any cheap vent material would do, even the plastic over wire meant for dryers.

My experience is that an Ozone generator gets the best results.

They're generally more expensive than filters or ionizers, but far more effective than a filter.

I don't know much about Ionizers, but don't liket the idea of having to clean something. There's nothing to clean in an ozone generator.

Hi,
OK, a smoker.
I have a Whirlpool Air Purifier, with an every-3-months replaceable black carbon type filter, and with a yearly replaceable HEPA filter. It does a very good job of filter out dust particles, cooking odors, and smoke from cigarettes.
My wife uses oxygen 24/7, and needs clean air to breath; also has allergies. This air purifier has been the best thing I have purchases, besides a very good vacuum cleaner!

It's a Whirlpool Wisperpure AP 450; and has an excellent write up by Consumer Reports magazine. I can highly recommend it. Have you also considered the cigarette smoker to step outside when he/she wants to smoke?? That would be the best solution!
PS; Consumer Reports magazine also recommends the HEPA filter over the Ionizer type purifiers. The Black filter in the WhisperPure is around $6, and the HEPA filter is around $78 from online stores; needed every year.

I really do like those hrv units. Question is these units require a intake and a outake to both the house and the outside (4 total). I also have to go through the roof also. If I have to install this unit in an attic above the room how would I do the intake and outake through the roof. Would a normal roof cap work for both the intake and outake or should I use something else. I live in a place where it snows a lot so I was concerned that the intake or outake might get clogged up. I would've liked to go through the walls or perhaps an eave but I cannot because the walls are made of concrete blocks and there isn't any eave on the house that is suitable for this. Thanks

I hate punching holes in the roof. These shouldn't need to be big. The drain vent roof jacks should work. You might be able to just let the intake come out of the attic. As long as it is well ventilated, it shouldn't make much difference. You just don't want to discharge moisture into it.

Advised by Heater serviceman today to "remove" hepa filter papers that I installed in my down air vents in all the rooms in my home. Serviceman's opinion is hepa filters restrict airflow out of vents. This causes overload on heater and also cause compressor in air conditioner to also overload.

Any one knowing about this, please comment

Nowadays air purifiers have become irreplaceable parts of our modern lives.
We can't ensure that the breath we are
Taking even in home is secure or not.
Air purifiers efficiently solve this
Problem.
