As much as I wanted this product to work, it doesn't. I have a pretty smelly laundry machine that is emitting odor all day long, I was hoping that two of these will somehow magically take away the odor. They didn't work for me.

It does not take away cat urine smell. It makes the smell worse. Will not buy again. It also leaves an unpleasant smell when used.

I was trying to eliminate or minimize the dog smell left behind from the previous owner of a car I bought. This "air freshener" did absolutely nothing to improve it. Haven't noticed one bit of difference since it's been in my car.

Not sure I would recommend it.  Even though it is supposed to be odorless ("no lingering fragrance"), it LEAVES a VERY STRONG ODOR...which is not any better than the odor we were trying to remove.
After three weeks, we still cannot get rid of the odor, and now we will have to sell the vehicle because we cannot neutralize this smell either!

Did nothing to remove the musty smell in my 2011 Mustang's AC.  It does shortly mask any existing smell, or rather mix with it because the odor of this product is VERY strong, but in my case, it did not fix the root of the problem.

Makes the car smell fresh.  But, it does not smell like leather.

I read the reviews and I thought it sounded like a great solution. My main reason for purchasing this product was the "odor control" that it would provide. It doesn't control any odor what-so-ever. It does push the poop to the end of the tray, but the cover doesn't close completely so the odor problem is just like it would be with traditional litter boxes. I'm going to return it. If you're looking for odor control, keep looking.

I bought a 2 year old car and the old owner smoked. It's only a slight smell and I didn't even notice it at first. The car had been completely detailed inside and out right before I bought it, carpets and floor mats cleaned and every surface wiped down. So the cleaning fluids probably masked the smell for a while. I was driving a friend a couple of weeks ago and he said it smells like someone had been smoking in the car. That's the first time I even noticed a slight, stale cigarette smell.  Based on so many positive reviews I thought I would give this a try, I figured for around $11 I've got nothing to lose! I put this in my car on Monday and it's now Friday. The unit has run for about 14 hours, and so far there has been no change at all - the same dull, stale cigarette smell is still there. I know this isn't very powerful, so I'll give it another week or so to see if it gets the smell out. So far I'm convinced the great reviews were written by employees of the company. I don't expect this to work even with another week of use. If it does, I will change my rating. If not, I'll try a true ozone generator. But if you have stale odors in your car that you just can't seem to get out, especially cigarette smoke, I would advise against this.

Update - Just over two weeks now, averaging 2-3 hours per day in my car, using this air purifier and it has absolutely no affect on the stale cigarette smell. Don't waste your money on this thing. Wish I could give it 0 stars.

Update 2 - I took the car to the dealer I bought it from who did an ozone "shock" treatment. That completely removed the odor. There was, however, a residual ozone smell that lasted about a week. but that's gone now too. If you have cigarette smoke odor or any other smell you can't remove, use an ozone generator. Call a detail shop, car dealer or equipment rental place. If you rent one, use it carefully because they can be quite dangerous.

The Good:
- It masks the others for a couple of weeks
- Relatively easy to use

The Bad:
- It only seems to mask the odors... as other reviewers have said, the [bad] odor eventually comes back
- Who doesn't love the small a new care? Well, this "new car" scented odor bomb does NOT smell good. This is only my personal opinion, but it stinks! It smells like some cheap motel or something...

Review:
I recently bought a pre-owned vehicle and, unfortunately, the previous owned smoked in it. I've been trying different things to remove the smell, and this odor bomb seemed promising. The reviews made me doubt how effective it would be, but I bit the bullet.

I prepped my car and set the odor bomb in place. The "explosion" seemed effective as it spread the smell pretty evenly in the vehicle. I left the car closed for about 4 hours and went back in.
The smell smoke was gone... but now I was being greeted by the smell of a cheap motel. I left the windows open and tried many things for days to vent the odor bomb's fragrance out of my car. Although it got tolerable, I still didn't like the scent.

It's been a couple of weeks and the fading smell of the odor bomb is revealing the smell of smoke is still there. At this point, I could've gotten my care professionally cleaned with all the money I've spent on things to get rid of the smoke odor.

I know some people have had positive experiences with this product, but I don't recommend it.

I purchased this because of the advertised "odor stop".  Not true. The day after placing, clean, new bedding, it smells again.

I placed this near the cat litter box, and it seems to work well in controlling the dust -- but, even with the charcoal filter, it does very little for the odors.  I clean the box twice a day, and (except for the dust levels) I really don't notice a difference.

as far as I can tell, it does not absorb any odor...placed it in the bathroom above my father's basement smoking room...still smell all the smoke and all the unpleasant bathroom smells

This air filter does not help against liter box odor from cats. I would not buy this again. . .

A squirrel has been getting into my house through a hole in a soffit. After following the directions and shaking for over a minute, I sprayed "Rodent Defense Small Animal Repellent" on a dry shrub. It had no scent that I could detect. Shook it more and sprayed again; still couldn't smell anything. Then I got my ladder out, climbed up to the soffit and sprayed a lot of it into the hole. The following day I happened to be outside and witnessed the squirrel climbing into the hole in my soffit. Actually, I was not surprised since I couldn't smell any odor from this product. I'm returning this product because it is defective.  It does not repel the squirrel that climbs into my soffit.
