Question: Does this work with keeping a room from smelling like cigarette smoke?
Document: Every morning when I come into the work room, the air is clean and fresh with no smoke residue! I love this little machine. With respect to the noise level - yes, on the high setting it is a little noisy but on low - which I think would work good for a smaller room such as a bedroom - it is hardly noticeable.
Find something else which maybe more effective.Only two stars because its not helping with allergens or the cigarette smoke smell
I bought this to use in my bedroom, and it work great. I am sleeping better, and my  nose doesn't get clogged up like before. I bought another one to use in the TV room.
I can not tell if it is effective against allergens because i did have a sneezing/cough from allergens while I was using this unit. I will update this review if things starts to change I notice a difference in performance.But my main reason for buying this was to see if it will help with cigarette smoke odor caused by neighbor smoking below me.
The product is good enough to cycle the air around, and on its quite mode i sometimes forget its on until the next day when i want to turn it on and see its been on :).I keep it by my computer since i smoke while i work. Its filters the air around em good enough so there is no cloud hanging above me :), but the smell and slight fogginess remains. But to be honest, it works as good as most air purifiers i got in the past.
The fast mode is noticeable but not an annoying sound, to me that is, and it powers through smoke easily within 5 minutes when cooking or smoking your preference. There are two ways to place the device, which I have it standing like a tower.
..Seems to cut the dust down quite a but and takes the smell of smoke when i occasionally do it in the house much faster than without. I bought another for the living room. Considering the price, i say this is worth every penny. Im satisfied.
With two cats and asthma this product is a life saver. We bought two for our apartment, one for the family room and one for the best room. They work great, are whisper quiet and clean very easily with a vacuum. We put the one in the bedroom on the highest setting when we sleep for white noise and it works very well.
At first I was a little apprehensive about buying this product as most of my Hamilton beach products were trash, but after reading the reviews I decided to buy it. BIG mistake. I was expecting the ugly cheap look, but I was not expecting for it not to work. After putting it in my small room for two weeks, it still smells and is dusty. What a pity.
Returned after a week of barely effective use. This air purifier has a major design flaw that causes it to work against itself. Air intake is on the front but outlet blows air forward from side/top (depending on vertical or desktop horizontal placement) so air is blowing out over the intake making this work against itself. Seems to be great at blowing dust etc around the room but outlet air disturbance over the intake prevents unit from drawing in all but completely floor level particles and even then, barely.
Answer: While I'm not a smoker, my son is. It will take a minute or two to clear the air, but the tobacco smell will shortly go away. As noted in my review I'm very pleased with the HB and suggest adding the 3M Filtrete to the installed filter if you have allergy problems. For the money, the HB is a very good buy! I hope this helps you.
