Ona Block Pro, 6 Ounce

This product is great. It is very strong at first. I like to move it around when I first get them to completely de-odor my car (one night in the car removes everything), closet, under kitchen sink, sump pump room. family members cars etc. then I move it to its final resting place where I intended it to go. I recommend buying a second one 3 or so weeks later and replacing the older one with the new one and moving the old one to a area that does not need as much odor control. It seems to make them last longer if you close them completely every once and a while and let them sit for a couple hours or a day closed. When they get really old put back on the cover and maybe save them. or move them to small areas like the trunk of your car, gym locker or bag, kitty litter room etc. attic, mudrooms, basements. I have also put some of those crystals that hold water that you can put in potted plants, in the ona block and I think it made it last longer.

I was skeptical about this product but thought I'd give it a try. I've had it for a couple months now. It is extremely powerful and, while the smell is strong, it is not offensive or artificial like other air fresheners can be. It's not noticeable as an air freshener i.e. it doesn't have a classic vanilla, coconut, citrus, or floral smell. It is very strong so I don't open it all the way. In fact all I did for the first few weeks was loosen the cap slightly. At this point I have the cap unscrewed but covering the whole top. I use it to freshen two small rooms in the entryway for my house. I have two dogs that frequent the area, cooking smells, compost as well as other strong smelling organics make there way through regularly. The Ona Block does a good job neutralizing the odors as opposed to covering them up. The air seems fresh.As always, keeping clean and regular fresh air exchange really helps odor control the most, way beyond any of these types of products. This just helps keep things neutral in the mean time.Worth it!

I have mixed feelings about this product, but I have to acknowledge that it does its job as intended. I bought it for a fairly small office so that I can vape without stinking up the place. In close quarters with the lid completely off, it's too strong and the scent is definitely noticeable. It smells like a mix of citrus and some unidentified industrial cleaning product, slightly reminiscent of a urinal cake.Resting the lid over a portion of the opening makes it less overpowering, but then I get concerned that it's not eliminating the odor of my vape. To reach a happy medium, I periodically remove the lid and gently wave it around the room like some kind of shaman performing a room cleansing ceremony. That seems to work well.

This stuff is no joke! I bought a used car that smelled like Snoop Dog camped out in it for a few weeks. I scraped out a few spoonfuls and put it on a plate on the floor of the car with the heat on high, circulating the air through the cabin to get the cabin filter into the equation. It took a few hours, but did the job well. Don't sit in the car while this is circulating, or your throat and lungs will regret it.Another way it worked well was on dog crap. I have two large dogs. After cleaning up the mine field that is my lawn after a few weeks, I threw everything into the trash can. It was hot out, and trash collection wasn't for a few days. I scraped a few spoonfuls right into the trash can and it Ona did an excellent job of neutralizing the smell.

Used in unfinished basement. The smell isn't overwhelming and made a noticeable impact on the damp basement smell.

Shipping and packaging were all great, no issue. I've never used this product before so all I knew to expect is from what I'd read on reviews..The smell is great, nice, and clean without being overpowering. Works well to eliminate odors, specifically I used it in the car as I'm a smoker.My one and only complaint is the duration of how long the product lasts. I'd read the average was about a month give or take. Mine only lasted a bit over two weeks and that was with holes poked in the top.Overall this is a good product and works as advertised. I know now I should buy 2 instead of 1 next time.

I’ve used ONA for years and stand by it! Will get the job done

All of the other reviews over exaggerated how strong the smell is. When I got mine and opened it, it looked dried out and had absolutely no smell left in my room for a week to give it a chance did nothing!!!
