ONA Gel Pro Continuous Passive Odor Neutralizer, 25.8 oz

If I could give this thing 10 Stars I would. We had something horrible die in the walls that started to smell thursday. By Friday it was so strong I was physically ill. We received this on a Saturday and set it up immediately and by the end of the day the smell had improved drastically and off to the point where I could actually walk around in certain areas of my house with mask, that previously I couldn't. I'll be buying more for other areas of my house to deodorize

WORTH THE MONEY. This one I bought was HUGE in comparison to the first ONA product I bought. It's half the size of your average ice cream container. If you need to get ANY smell out of ANYWHERE an ONA jar is the way to go. The gels do dry out much faster than the ONA Block series but they work just as well to ELIMINATE odors. I used an ONA block in the trunk of my car that my sister spilled her gas can in and I couldn't drive without smelling it, and ONA extracted the smell OVERNIGHT and I never had the scent return. And she spilled more than a sip of gas, more like a cup or even a quart. This order went into a bathroom that backed up and we couldn't get the smell out. No more FUNK now, thanks ONA

This stuff is incredible. Been using it for years. It doesn’t mess the odor. It somehow cleans the air. Don’t know how but I know it works. You can’t go wrong.

The pro gel definitely does a good job at eating odors, although not perfect. The Gel lasted longer for me than it did other reviewer's, but maybe my household humidity is a bit higher than theirs. I also left mine in the corner of a room and there is not much air going over it (not to mention I only left the lid ajar on the quart), so maybe that is why I had no longevity issues.

This is very different than something that masks smells, like Febreeze. This is an odor deodorizer, which actually attaches to the particles and deodorizes. This stuff is legit. It has a scent similar to a urinal cake, but it's not bad, it has a chemical-type smell. This will get rid of even the strongest odors. If you blow a fan on it, it will not last nearly as long, but work much quicker. It is a jello-like gel that will dry out when & evaporate. If you use a fan, you can rehydrate the gel, which will increase its use, but it'll be less potent. I don't use the fans, I just put it out on a dish. Highly recommend, even though it's pricey.

I got this because my roommate is highly allergic to weed, and apparently there is a small bit of weed residue left over in my house. He is affected even though the residual level is too low to smell. I got this as an experiment to see if it would help. It didn't help. So that's unfortunate. But I did try to use it for something it is not specifically advertised for. This is designed to absorb odors, and it may be that the remaining residue is now odorless but still affecting him. In any case, the smell of the gel is pleasant, and I currently have the jar open in the house. It was very strong at first, but now that it has been open for a few days it is mellowed out. It makes the room smell fresh and clean. I like it. I don't really have any other odors I'm try to cover up, but if I did, I'm sure it would work quite nicely at eliminating them. My roommate tried having the jar open in his bedroom when we first got the jar, and he said it made his eyes burn. I guess that's why some people just drill little holes in the cover, instead of taking the cover completely off. I read somebody's comment that it smells like a dentist's office, and it kind of does. But that's not necessarily a bad thing. It smells clean. So I like it.

Definitely eliminates/ reduces unwanted odors 🌱

I used to work at a gardening store that sold Ona, so I knew it had a good reputation for getting rid of strong, skunky odors. I had a skunky odor problem of my own, so I bought the Ona Gel (on accident, I wanted Ona Block, but that's okay, Gel works fine). I drilled some holes in the plastic lid and set it up by my air purifier so that the outgoing air would pass over the Ona container. This worked extremely well, eliminating all smells in my apartment. I'd wake up in the morning and walk into the living room, and it would smell like Ona and not anything else, so the Ona was actually being circulated around my apartment somewhat by my office air purifier and maybe the HVAC system. Only problem is that my eyes started hurting and I was getting tiny little styes all the time, with red patches and little white pimples under my eyes, and the area under my eyes was very tender and hurt if I rubbed it. After a few days, it dawned on me the only recent change was setting up the Ona on the air purifier, so to test the theory out I put the Ona away in a cabinet and by the next morning my eyes were 80% better and by the second day they were 100% better. So I think clearly something in the Ona was irritating my eyes. So while the Ona Gel definitely eliminated any and all odors in my apartment, I don't think I will be able to keep using it. It's a shame, because even when running two HEPA air purifiers in my office, it can get very stinky and stay stinky for a long time without the help of Ona. I don't think everyone has this problem, and maybe I wasn't meant to leave it out at all times, but I did see one other review about someone saying it affected their roommate's eyes, so I am not alone in this!

Fonctionne mais l'odeur n'est pas neutre

The smell can be overpowering out of the container... However! We decided to scoop a few spoonfuls of the gel pieces into glass ramekins. We then placed one ramekin in each room of our house. And wow! The odour is very mild, sometimes indiscernible. When you do smell it we find it smells like a cleaning product - inoffensive, pleasant and refreshing. The gel lasts a few days in a well ventilated area, so a little goes a long way with this stuff. All in all this product is very good and it helps immensely with smells of dog or smoke.

great size container, really does work to remove those odours its not instant but it does help. nice pleasant fragrance. Can be potted into smaller pots for longevity. Very versatile and great value for the size.

Capté bien les odeurs, bon produit

Increíble cómo absorve prácticamente y camufla el ambiente con un toque sutil a limpio. a la hora de su apertura cualquier mal o buen olor lo elimina del ambiente.
