Why Use an Ozone Generator?

Ozonics OrionX Ozone Generator -...

As any hunter worth their salt knows, animals can get spooked by the smell of a human lingering nearby.

Though most of us can’t detect it, our bodies produce faint scents that can act as a danger signal for animals like deer and elk.

You cannot do much to hide your scent when you’re out hunting. Even if you’re freshly showered, your hunting clothing and gear will likely reek of humans.

This can affect your chances of bagging that prize buck you’ve been after.

Ozone generators are a relatively recent phenomenon. They offer an effective and high-tech solution to the smell that hunters have sought for centuries.

These generators block smell molecules that might otherwise reach nearby animals by producing a cloud of ozone particles.

Using an ozone generator in addition to visual camouflage can make you virtually invisible to passing wildlife. You’ll be able to sit wherever you want without worrying about scaring your quarry away too early.

Using an Ozone Generator

The best ozone generators for hunting are easy to use. Hit the button, and give it some time to run. It may take some time to produce enough ozone for a noticeable effect.

Most hunters assume they only need to use their ozone generators in the woods. For maximum effect, however, you should also use the generator before your hunting trip to eliminate any scent from your gear.

If you run your generator in a closet for about 24 hours, the ozone particles will neutralize all of the human smell your gear absorbed while in storage.

Don’t forget that you need to clean your ozone generator regularly for it to function at max capacity. Most models have plates and filters that need cleaning every two months or so. However, some models may need more frequent care.

What to Look for in an Ozone Generator?


You can find extra-large and industrial-size ozone generators, but generally, these will be more than you need for a simple hunting trip.

Instead, it’s best to stick to a small, portable ozone generator for hunting. If you use ground blinds, ensure the unit will fit comfortably inside you.

It’s best to look for something easy to store in your closet. Even in operation, it should be relatively small and out of the way so you don’t accidentally bump or knock the unit.

Models like the BoneView Ozone Generator are designed to fit comfortably in your pocket.

The Volume of Ozone Gas

Different ozone generators produce different levels of gas, which can affect how effective it is against sensitive noses. Most of the time, the volume is measured in milligrams per hour (mg/h).

A generator that produces 5,000 mg/h to 1,000 mg/h is usually sufficient for personal use.


In addition to the volume of gas a generator can produce, you should look into how wide of a radius it can cover.

No matter how much ozone a unit is pumping out, it’s not going to do much good if it’s only able to mask a portion of you.

Models like the Wildgame Innovations ZeroTrace Plasma Ion Unit use a fan to dispel ozone particles as far as possible.

Which Ozone Generator Wins?

An ozone generator is a great way to hide your scent from wary prey as you hunt. It allows you to settle down wherever you like without fear of being detected, even when you’re camped out upwind.

We think that one of the best ozone generators for hunting is the Wildgame Innovations ZeroTrace Plasma Ion Unit.

It’s more affordable than high-end options such as the Ozonics Orion, but it still offers better odor elimination than models like the Boneview Ozone Generator.
