Promising review: "This might be the best product I’ve ever owned. I know that sounds dramatic but it’s truly life changing. I have terrible allergies including being allergic to cats which I have two of. This helps tremendously. I put it in the same room as their litter boxes and the smell is completely gone. Like 100% gone. Not just masked or covered up. I’ve tried so many things to help with the smell and nothing has ever worked like this. I actually watched a clump of fur in the air get sucked into the machine… wow!! Super easy to set up, doesn’t take up too much space or look bad, love everything about it! Highly recommended especially if you have allergies and/or pets. If you’re considering getting this, get it!!!! (Also side note, I just used the regular filter that comes with this. I know they have one that’s specifically made to help with pet odors and allergies but so far I find the original one works great for me and my cats but if you have more animals or stronger odors and find the regular doesn’t work, try the pet-specific one?!) (I also use it on the highest setting and it does have a “white noise” sound to it but it doesn’t bother me personally and I don’t find it extremely loud.)" — Amanda
