When I first heard about the CritterZone on Hauspanther, I was intrigued. Kate Benjamin calls the air purifier and odor eliminator a “game changer. ” Kate has 12 cats of her own, and combating odors is something that she deals with on a daily basis, so I figured she knew what she was talking about. I wanted to learn more about this air cleaner, and contacted the company. When I received the two sample units they sent me, I couldn’t believe my eyes: they’re tiny!

The CritterZone Air Purifier is only 4.5″ tall by 2.75″ wide by 1.75″ deep. The wall plug in unit protrudes about an inch from the wall in the back of the unit.  The cord that comes with the corded unit protrudes less than .5 inch.

I have to admit, I was skeptical. How could something so small really do anything to reduce odors?

Works great on kitchen odors

I plugged the unit into an outlet in my kitchen after I had reheated some split pea soup, which has a pretty strong smell. I’m funny about cooking smells – I love them before and while I eat, but I want them gone as soon as I finish. I can’t stand lingering odors. By the time I finished my bowl of soup, the kitchen no longer smelled like soup!

Works great on pet odors, even urine

But I’m sure what you really want to know is how it works on pet odors. I tested the unit near one of our litter boxes. Ruby is a vertical pee-er, and before I got the NVR Miss, the only litter box I’ve been able to find with high enough sides to eliminate this problem, we had some accidents. Even though I had used numerous cleaners around the box (it sits on carpet), I’d still occasionally get a faint whiff of urine odor. I only had to run the unit there for 10 minutes, and the remaining faint odor was completely gone. I haven’t smelled it since.

October 2014 update: I had a chance to use the Critterzone on a urine stain on our carpet when some of Ruby’s urine spilled over the sides of our high sided box because I had filled it with a little too much litter. After blotting the stain, and putting the Critterzone upside down on the damp area for about half an hour, there was absolutely no odor left.

How does it work?

The Critterzone produces a natural ionic flow to give indoor air the energy it needs to restore itself. This process virtually eliminates pollutants in the air, on surfaces and even in fabrics, providing odor and germ control. The unit uses very little energy and cleans your air 24/7 for less than a penny a day.

The unit is said to eliminate spills, urine and odors from carpet, upholstery, mattresses and more. They say that it can virtually eliminate human or pet urine from fabrics within 30-60 minutes. It can be used on spilled milk, gasoline and other germ or odor concerns in your home, business or  vehicle (it comes with a car adapter that plugs into the cigarette lighter).

The best part: no filters, and you never have to clean anything, ever!

My only concern about the CritterZone was the issue of ozone. The unit emits a faint ozone smell when it is in operation, similar to what you would smell during a thunderstorm. Some air purifiers on the market are ozone generators, and there are safety concerns around the levels of ozone these machines generate. The FDA requires ozone output of indoor medical devices to be no more than 0.05 ppm. The Critterzone produces less than 0.01 PPM of ozone.

I absolutely love this unit. I’ve shied away from larger air cleaners because they require frequent cleaning, as well as purchasing replacement filters, not to mention that they take up space. This small, efficient unit gets the job done!

At $99, this is a bit of an investment, but it will save you from having to buy bottles of odor eliminator, and remember that you will never have to buy replacement filters. And if you’re not happy with your purchase, the company offers a 30-day money back guarantee.
