OK I don't think it eliminates any odors.

Moves more air than old filter.  I don't think carbon eliminates any odors.

This doesn't smell as fresh as the freshwave crystals. Maybe it still absorbs odors. I don't know. I'm not buying again.

After reading the review I thought it would be good at removing odor. Unfortunately, It didn't.
Earlier this summer I got this stinky mildew from the air vent, so I think it may be the time to clean the A/C. Since I am not really a professional mechanical expert, I purchased the East-to-Use one with this. Plus, I got a new air filter.

According to the instruction on the can, I removed the blower and air filter, applied it directly on the evaporator core, and waited for 20 mins. then I turn on the A/C to dry out the core. Everything seems fine that day, stinky smell is gone, and air is refreshing. However, it did not last long. I got those stinky smell second day.

So I used the ETU version. That one wet the may, left some residue on the seats, gave this unbearable smell, yet did not remove the mildew odor.

So I guess I will never buy any product like this.

This seems to take care of pet odors for a period of time.  I wouldn't agree with "Gone for Good" but, it does eliminate odors for a little while.

I think it's doing its job.  I don't have any odors coming from the drain, so I really don't know how to judge it.

Doesn't seem to move much air. But it does seem to remove stale odors fairly well. My son gets carsick and this seems to help.

It just has a strong odor to mask the smell. It didn't seem to remove the smell. I'm always willing to try something new to see if it works better than what I know. Back to what works.

This gel in the container does not make much smell.  But, maybe it clears the air.

This does not work well to remove smells. However it keeps small insects out so they don't lay eggs in the compost bin.

This thing doesn't work as far as I can tell. I bought it to put in the room that my cat litter box is in to help with odor and the dust. I run it on high on low for an hour or overnight, it doesn't make a difference. It still smells and there is still dust so I would save your money if you are looking for odor air cleaning.

You can barely smell it unless you bring your nose it. It is simply not as powerful as other air fresheners.

Worked a little bit but did not get rid of all odor

It seems a good product, but I didn't experience the dramatic results that were advertised.
I used it to try to contain odors coming from a litterbox used by two cats.
Maybe it's just not enough for this task and for other situations can work more properly.

I tried it.  Attractive.  simple design.  I couldn't tell if it worked or not.  I guess I'm not sold on the theory of this removing odors from my hand.  If this kind of thing actually works, this particular item would be fine.  I just can't tell if it works.

Purchased with the hopes of helping to reduce odors after cooking, I cant tell a difference between this and a normal filter when it comes to odor reduction. Smells from cooking still linger for hours or until I vent the place out.

OK air filter but don't buy the hype about removing odors.  It just doesn't work for odors such as neighbor's apartment cooking.  Stinks just as bad and only time will remove the odors in the air.  Does not speed up this process!  Expensive trial and error so save your money, enough said.

Not sure of its purpose. It doesn't smell like anything and it doesn't soap up.
