I was so desperate to remove the cigarrere smoke smell from my 745 sq Ft rental unit after my tentant had been smoking in there for 10 months. Everytime I walked in I could smell the smoke and I would come out with my clothes smelling like smoke so I decided to give this machine a try since it was only $68 instead of paying a company $300 to treat my home and this little machine actually worked! The smoking only occured for about 10 months and since my unit was pretty small the machine did the trick! I just turned the AC on so that there was airflow in the unit, closed all doors & windows and treated each room for 120 minutes seperately for better results. After the first two hours I noticed a huge improvement. I ran anoter cycle to finalize things and now the SMOKE SMELL IS GONE! Now my unit smells fresh when I come into the unit.

I own a well-loved pricey Dyson hot cool fan/purifier. When I was looking to buy an additional air purifier, I wanted a simple, mid-range product. This purifier not only fits the bill, but also does more than my expectations.
I have chronic sinus problems and can feel better air quality after running this purifier in my great room(300 sf) for about 15 minutes. It is very easy to operate. The auto setting automatically monitors and reacts when needed. The noise control is super, I can barely notice any noise when it is on lower fan.
Compared with my Dyson's air purifier features, this purifier doesn't have Dyson's bells and whistles, but if all you need is a solid, effective affordable air purifier, this is the one.

This is great machine. My house is really old which was built around 1950. There is wired smell and hard to get rid of. Mostly I used the perfume spray. It works temporarily after a couple days. I searched google and many reviews told this kind machine works to reduce scenarios. I am so glad to have it. I turn it on when there is no person at home during daytime and turn it on before we get home via WiFi power cord. It works so good to reduce smell.

As soon as I RECEIVE this equipment.Turned it on to test make sure you are out of line of fire. Created a ton of Ozone the second I turned it on. Works great on certain smells. I have tried on a teenagers funky butt smelling room worked great. A smokers room worked great. Im sure many other smells can be removed with this.

Great for getting out smoky smell in rented house. I used it to rid the house of bad odor left behind by tenants. You need to buy one because renting would take more than one time Repeated about 4 times smoke is gone. Also used to rid my home of odor. Closed off bedroom and left it in there. The bed sheets smell close line fresh as do my clothes that were hanging in the closet. Added bonus bugs were found dead in rental.

Overall this product is really amazing. I use it once a week for 30mins after I go to work in my apartment (roughly 700 sqft). It deodorizes the smell of the leftover in my kitchen as well as the odor of formaldehyde (new apartment). Just remember to open the windows after used to allow circulation. As an ozone generator, it absolutely functions better than most of the so-called air purifiers in the market. I know it was widely used in commerce and industry, but I definitely recommend to expand its usage in daily life as well.

I bought this for my parents because they are big smokers....When i go back home I hate to smell the smoke! This product helped me out alot and my parents love it! It cleans the air in a very short time! It is very easy to use! I give this product a 5 star because it did what i wanted it to do with a very good price!

I bought this a couple weeks ago and I have to say it met my every expectation, so far. This thing got rid of all the "old musty gross" apartment smells in my apartment as well as the overpowering stench of hamburgers and cigarette smoke residue in my father's car.Food smells in the kitchen? No problem. Mildew smells in the basement? No problem. I highly recommend this product to anyone wanting to rid a space of any organic odors that may be present. The only caveat I would offer is that if you're wanting to use an ozone generator in a larger space you may wish to consider one which has a "hold" option that allows the unit to run continuously.
