ONA Gel Pro Continuous Passive Odor Neutralizer, 25.8 oz | Essential Oil Formula, Continuous Odor Control, Pro Scent, Passive Diffusion, Long Lasting

Definitely eliminates/ reduces unwanted odors 🌱

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.

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 haven't had the chance to put it against any of my more problematic smells, but just sitting in its jar it takes care of a lot. Unfortunately, the smell is produces isn't the best. It's not bad by any means, but its heavily reminiscent of fresh urinal cakes. It was also packaged very poorly. Loose in a box with packaging tape wrapped all over the jar to prevent leaking (which didn't work--it arrived with about 1/8th its gel all over the box). However, the gel does what its supposed to and does it well. Use for serious smells.

Works great!

Smells great. I have smell triggered migraines and the smell did not bother me. It doesn’t smell like chemicals. It just smells clean, not overpowering. Gets rid of “party” smells ;) and helps my 125 yo house smell so good. My only issue is that they do not make the liquid in this scent. I would prefer the liquid.

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!

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

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.

Funziona perfettamente, lo consiglio, non è affatto fastidioso e assorbe davvero gli odori
