Q. What makes Scent Crusher an expert on ozone?

A. While we aren’t trying to solve any issues with the earth’s ozone layer, we have spent considerable effort to understand the use of ozone as a cleaning agent and in developing products that safely and reliably eliminate odors and kill potentially harmful bacteria.

Our engineer has years of experience in water purification and gas management systems, including leading ten separate teams in product development and manufacturing efforts on the International Space Station. Like many historical advances in consumer products, Scent Crusher’s development has roots in the space program. We were able to use our engineer’s expertise to better understand the impact of ozone on items commonly used in sports gear and on bacteria commonly found in active settings. We believe this sets us apart from others in our industry.

Internally we have performed thousands of hours of testing to improve our understanding of the impact of ozone on odors and on the materials hosting the odor. We have invested significantly in 3rd party testing to determine the necessary ozone application techniques to kill bacteria at over a 99% effective rate. In short, we believe we have the best understanding of applying ozone in products for hunters and sports enthusiasts in the industry and we continue to invest to maintain that position.

Q. Is ozone harmful to humans?

A. In high concentrations ozone can cause harmful reactions, particularly to the respiratory system. There are federal safety standards limiting the amount of ozone that can be released into the air. Our products are designed to be well within those standards when used properly.

People have differing reactions to ozone exposure. In some people, lower levels of ozone may cause dryness of mouth, eye or nasal irritation and mild headaches. If this occurs, move the person to fresh air and/or wash eyes gently with water. If conditions persist, seek medical attention as appropriate.

Q. What are the typical odors and bacteria killed by ozone?

A. Pretty much everything. Ozone is one of nature’s most powerful oxidizers and has been used as an organic cleaner for years. Nearly all bottled water is treated with ozone and many municipal water systems around the world use ozone to treat drinking water. In addition, ozone is used by hotel management and disaster recovery firms to eliminate odors caused by smoke or water damage.

We have tested our products using common smells like sweat, smoke, food, animal scents (including skunk) and have used third party labs to test bacteria and viruses including MRSA, Salmonella, Norovirus and E.coli. Ozone was shown to be effective at eliminating or killing these smells and organisms.

Q. Does ozone have a smell?

A. Ozone has an odor somewhat similar to chlorine, detectable at fairly low levels of concentration. As ozone is exposed to air it quickly reverts to ordinary oxygen so its smell dissipates quickly.

Q. If ozone has a smell, why can’t deer smell it as well?

A. In the hunting arena, our products are designed to clean and disinfect your gear before and after the hunt, not during. Ozone dissipates rapidly when exposed to fresh air, reducing the potential for detection. Even if residual ozone is present, it is less likely to alarm deer since ozone is a naturally occurring smell, frequently noticeable after a rain storm with lightning.

Q. How do I know how long to use a particular product to eliminate smell and kill bacteria?

A. Over time, we have modified our generators to run for a maximum time of 30 minutes for one application. In most situations, this will clean and disinfect your gear. If smells are more ingrained in the fabrics or materials, you may need to use the generator for more than one cycle. We strongly recommend that you allow the unit to remain undisturbed for an amount of time equal to the run time prior to opening and then allowing fresh air to be exposed to your material, before beginning another cycle. This process will reduce some of the potential impacts on the materials.

Q. How long will the anti-bacterial effects of ozone last? Will bacteria return or will the clothing be “scent-free” until it is worn again?

A. Ozone reverts to Oxygen quickly, so there is no lingering ozone present to continue to kill bacteria after the initial cleaning cycle. However, ozone does kill the bacteria it contacts, so once your clothing is scent-free, it will stay that way until bacteria are re-introduced.

Q. How does ozone affect clothing or other materials?

A. The short answer is that we haven’t seen significant impacts on the materials typically used in hunting gear after applying ozone for normal periods of time at typical intervals.

While we would love to say ozone has no effect on clothing or other materials found in hunting or sports gear, our testing has shown that, much like ordinary laundry, ozone does have some impact over time. For example, we designed a test to determine whether clothing subjected to high ozone exposure over a relatively short period of time would deteriorate. While the shirts used didn’t suffer significantly from a structural standpoint, the darker fabrics did see some fading at the end of this unusually prolonged test.

Q. How will Ozone impact my special purpose hunting clothes?

A. Many of the expensive carbon-lined fabrics used in hunting become less effective over time as they are laundered. Using Scent Crusher products like the Hunter’s Closet and the Gear Bag will allow you to effectively clean your clothes with fewer trips through the laundry cycle, thus extending the effective life of this specialty, expensive clothing.

Q. Can I use the Scent Crusher products on bibs with elastic straps? How about water proof rubber boots? I’ve heard that ozone can harm elastic or rubber items.

A. We do not recommend using the Scent Crusher products to treat bibs or boots with significant elastic content or rubber content. Ozone can harm certain elastics and rubber products.

Q. There is a tag in the Scent Crusher Gear Bag that says to not place rubber or elastic products in the bag, but my manual says to only run the bag for 10 minutes if using with rubber or elastic. What is the correct way?

A. We have previously attempted to distinguish between products with differing levels of rubber or elastic that responded differently to our testing. However, we have continued to test the impact of ozone on common hunting garments and are recommending that you not use the Scent Crusher products with products with significant elastic or rubber content. While it is possible that some garments will not be impacted, we prefer to err on the side of caution.

Q. Will Scent Crusher products work to eliminate odors not caused by bacteria, like gasoline or other chemicals?

A. The short answer is yes, but it will very likely take longer and require more ozone exposure to eliminate the odor. Scent Crusher products were designed to eliminate bacteria and the odor caused by bacteria that occurs while participating in outdoor activities like hunting. In the case of chemical-caused odors, the break-down of the odor causing elements will take longer since products like gasoline have much more complex chemical compositions. The effectiveness of the product and the time required to eliminate the smell will also vary greatly depending on the extent and exact nature of the chemical exposure.

Q. Can I use Scent Crusher products to eliminate odors from athletic equipment and clothing?

A. Again the answer is yes. Depending on how long your gear has been used and the nature of the clothing or equipment, the cleaning process may take longer due to the accumulation of bacteria and odor. For example, your one year old running shoes that have hundreds of miles on them will very likely take several cycles in a Scent Crusher bag or closet to get good results initially.

Q. Can I use the Ozone Go while driving my car?

A. As a precaution, we do not recommend being in the vehicle when the Ozone Go is operating. While the unit does not generate ozone at extremely high levels, some people experience mild headache and minor nasal discomfort when exposed to the lower levels of ozone present while the Ozone Go is operating.

Q. Can I use the Gear Bag inside a vehicle using the car plug while I am traveling in the vehicle?

A. The gear bag is coated to prevent excessive seepage of ozone into the surrounding area.  While you will likely smell a small amount of ozone, it should not be enough to cause any impact on the occupants of the vehicle.  Some people are impacted more by ozone than others.  If you do experience mild headache or nasal discomfort, simply open the windows slightly or discontinue using for a period of time.

Q. Does the car need to be running for the Ozone Go to work?

A. The unit works best when the car engine is running; however, it will also operate effectively in many vehicles with only the auxiliary power on. If using without the car running, you should monitor your car battery to make sure you do not drain the battery excessively.

Q. How effective is the Ozone Go in eliminating cigarette smells from cars?

A. It depends. If you have an occasional cigarette in your car and want to eliminate the smell, the Ozone Go can be quite effective when used normally. If you have months and months of accumulated smoking smells, the Ozone Go alone will not likely cause a significant reduction in the cigarette smell in your car. When combined with other deep cleaning efforts (for example, those offered by car detailing centers), the Ozone Go can help eliminate lingering cigarette smells.

Q. The generator operating manual says to not run the generator for more than 30 minutes over an 8 hour period. Is this to protect the contents of the bag or the generator itself?

A. This warning is intended for the contents of the bag or closet, not the generators themselves. We have amended our newer manuals to better explain this caution. The new manuals suggest not running the units for more than two or three cycles over an 8 hour period to help reduce any potential impact on the contents. This warning is out of an abundance of caution as most materials will experience little to no degradation from exposure to ozone. If you are treating multiple loads of clothes or gear and changing the contents between cycles, there is no problem using the generator as many cycles as needed.

Q. Can I completely fill a bag or closet with clothing or gear and get the same results when treating just a few items?

A. You should achieve best results by filling the bag or closet to roughly 50% capacity. This will allow the ozone to circulate freely around the contents. Smaller loads can also be effectively treated, but you may be able to run the generator for a shorter period of time to achieve good results. If you have more clothes or gear to be treated than will easily fit in the bag or closet, we recommend running multiple loads.

Q. Where are the hoses supposed to be placed inside the bags and closets?

A. The hoses are flexible and long enough that you can place them where you wish. Best results are achieved when the end of the hose is not obstructed and placed on top of the items in the bag or near the top of the closet.

Q. Are the closets airtight?

A. No. The closets are lined to prevent excessive seepage of ozone, but they are not completely air tight.

Q. Does the closet have a bottom covering or does the unit sit directly on the ground or floor?

A. The closet is completely enclosed and the bottom surface is reinforced.

Q. Are the bags and portable closets waterproof?

A. The bags and closets are water-resistant and will withstand a morning dew very well. We do not recommend leaving them in a heavy rainstorm or submerging them in water as they were not designed to be completely waterproof.

Q. Are the generators in the gear and roller bag TSA compliant?

A. Based on our reading of the Transportation Security Administration’s Prohibited Items list, the ozone generators would not be prohibited as carry-on items. The prohibited items list is available at

Q. Can the generator be used as a stand-alone air treatment unit?

A. The generator was not designed to be used in that manner. It was designed to deliver an appropriate amount of ozone to kill bacteria on clothing and sports gear within a closed, lined container.

Q. Can I take the generator from one of your products (e.g. the gear bag) and use it in another bag or closet I already own?

A. No. Each or our products was designed to accommodate the size of the generator and the release of ozone into the surrounding environment. For example, the gear bag and flexible closet are both coated to prevent seepage of excess ozone outside the unit while the generator is running. While the generators in the units are similar, we do not recommend using them as stand-alone units for other purposes.

Q. Do you sell clothing and other promotional merchandise?

A. We are planning to sell a limited amount of clothing and hats on Amazon beginning in late September of 2016. We have included decals and stickers with some of our products and have distributed the rest of these to our Dealers, Retailers and Professional Staff. In the future, we intend to make a broader selection of merchandise material available to the general public.
