Disinfecting Air & Surfaces

with

Chlorine Dioxide

Helps destroy viruses, bacteria, mold, and fungi in the AIR, and on surfaces, skin, clothing, furniture, hard surfaces, and food, and in water.

Using the compound chlorine dioxide in the air around people provides significant protection against respiratory diseases. Germs are destroyed not only in the air but also on surfaces the mist or gas contacts, including on people and clothing. Because of chlorine dioxide's unique chemical action, it is highly effective even when used at extremely low concentrations.

Example results of use in air:

  • In school cafeteria, distribution of chlorine dioxide via humidifiers reduced viruses by 30% and bacteria by 65%. 

  • Employees in a military building using chlorine dioxide gas had 68% less incidence of flu-like illnesses.

  • Chlorine dioxide in air protected 10 out of 10 mice in a study from airborne flu virus even when used at an extremely low level of 0.03 ppmV, whereas 7 of 10 unprotected mice died.

  • In one grade school classroom with a simple chlorine dioxide deodorizer, students' low rate of colds and flu contributed to 60%  fewer absences.

  • Testing found chlorine dioxide to substantially inactivate three common bacteria when used at air concentrations only 1/10th of safety maximums.*

* OSHA affirms chlorine dioxide to be safe to breathe 8 hours a day for a 45-year career at 0.1 ppmV (~0.3 mg/m3) in air. The NIOSH recommended limit for short-term exposures is 0.3 ppmV (~0.9 mg/m3) for 15 mins. twice during an 8-hour workday.

Versatile

MULTI-PURPOSE DISINFECTANT & SANITIZER

Chlorine dioxide is a chemical compound that is effective against a very broad range of pathogens, including many types of bacteria, viruses, fungi and molds. Only very low levels of chlorine dioxide are needed for high effectiveness. Several products that contain chlorine dioxide (or sodium chlorite that is "activated" to create chlorine dioxide) are on the EPA's List N of disinfectants to use against the COVID-19 coronavirus.

Chlorine dioxide's is an environmentally friendly disinfectant that works very differently from chlorine bleach--by "oxidizing" rather than "chlorinating." It's chemical action is much different than that of chlorine bleach. Chlorine dioxide is also gentle on the body because it reacts selectively with only certain types of molecules, and its action is naturally counteracted by substances in the body.

Super Convenient

TO USE IN SPRAY BOTTLES & HUMIDIFIERS

Methods to use are simple, supplies are easy to obtain, and costs are very low.

Air

 Misting upwards into air with a fine-mist spray bottle can disinfect many air particles and surfaces contacted by droplets. Running a fan can help mist stay in air longer for better distribution.

An ultrasonic humidifier provides even more effective coverage of aerosols and surfaces.

Clothing

Use as a quick, helpful precaution after coughing or touch, or visiting a potentially infectious place.
Mist over your clothing and then use your hand to gently smooth it out across the surface. Normal disinfectant concentrations are non-bleaching for most fabrics.

Hands

Spray Solution onto hands and rub on skin for 20 seconds, then allow to air dry, or wipe on towel.

Does not draw moisture out of hands, though skin may become slightly rough

if sprayed very frequently.

Furniture

Spray several inches above furniture, and then spread across the surface with your hand. Suitable to to use on most upholstery, wood and metal. Allow to air dry, or wait 5-10 minutes before wiping dry any furniture that shouldn't remain damp.

Surfaces

On hard surfaces, spray or wipe thoroughly enough that no spaces remain between droplets and the surface stays wet for at least 5-10 mins. Let air dry. Solution leaves no significant residue so doesn't need to be rinsed or wiped off.

Step 1.
Choose the best chlorine dioxide product to match your needs

Visit THIS PAGE for list of several Chlorine Dioxide & Sodium Chlorite products.

There are 3 main types to choose from.

Ready to Use

The most practical solution for many people. Comes in 1 liter, 4 liter (1 gallon), and 20 liter sizes.

Product concentration is consistent.

Effectiveness usually ranges from 1 to 12 months. May come with spray bottle.

Easy Mix

Less confusing to mix than commercial types.

Products may be tablets, powders or drop-in pouches for easy mixing. May include spray bottle.

Full-strength effectiveness usually ranges from 2 to 5 weeks after activation.

Shipping is very economical, and it is easy to keep additional supplies on hand.

Commercial Type

When making small quantities, mixing instructions can be challenging to follow. Mistakes can result in inconsistent mixtures that may not be obvious to notice, but often are within an acceptable range.

Full-strength effectiveness usually lasts 2 to 8 weeks after activation.

Step 2.
Select the tools you want to use.

View some suggested tools

Chlorine dioxide is deteriorated by types of light, so containers need to be non-transparent. You can spray paint them if needed.

 

Using a very fine mist spray helps ensure more thorough contact with germs in air particles and on surfaces. Continuous pressure spray bottles from beauty stores are good choices and make less distracting noise, However, many ordinary trigger pump spray bottles also produce fine mist.

A travel-size hairspray or other fine-mist bottle can fit in your pocket for easy sanitizing of hands, surfaces and air throughout the day.

 

An "ultrasonic" humidifier is best because it produces finer droplets and usually does not have a filter that reduces chlorine dioxide effectiveness. If possible, keep any transparent parts of the humidifier away from light, or spray paint them. Use distilled water to minimize mineral build-up. Chlorine dioxide will prevent bacteria, mold and fungus from growing in the tank, but the humidifier should be wiped out every few weeks. When using chlorine dioxide, demineralization cartridges and filters should not be used.

Step 3.

Mix a multi-purpose
Spray Bottle Solution

Note: If your product is one that uses "activator," do add it.

SARS-CoV-2 is an enveloped virus that is considered easy to inactivate with disinfectant. Many chlorine dioxide disinfectants can destroy coronaviruses in about 30 seconds.

 

Most products at their common "general-purpose disinfectant" strength will destroy human coronaviruses. Check your product's label for the appropriate concentration to use. For most chlorine dioxide disinfectants, an effective concentration in liquid would generally be between100 to 300 ppmV.

 

If a product comes pre-diluted and labelled as "ready-to-use" for general-purpose disinfection,use full-strength.

Step 4.

(optional)

Mix a Humidifier Solution

Our Chlorine Dioxide Formula Calculators can help you formulate amounts for mixing correct concentrations of ingredients. How much to mix will depend on the concentration of your starting chlorine dioxide solution, the size of the room, and the flow rate of the particular humidifier you choose.

Visit our Chlorine Dioxide Formula Calculators page to learn more about the amount and concentration of chlorine dioxide liquid solution to use in your humidifier or diffuser.

(Note: There are alternate methods for disinfecting air with slow-release gas deodorizers, or using an aquarium air pump and air line to aerate chorine dioxide solution in a bowl in 30-minute dosages. More information on these methods to be posted in the future.)

Step 5.

Use these tools to enjoy safer shared spaces!

Multi-purpose spray

 

Hand out personal-size spray bottles, and place several larger ones around sinks, countertops, and seating areas, etc.

On most surfaces, moderate amounts of chlorine dioxide disinfectant have little more effect than water. They also do not leave sticky residue, so they do not need to be wiped off.

 

Chlorine dioxide spray is also very effective and convenient as a hand rub sanitizer that is mild on skin.

Worry-free air mist


When using a spray bottle, concentrations even as high as 700 ppmW can be used, because a small amount of liquid is diluted in so much air, but even much lower concentrations can provide substantial help.

 

Spray upwards into air throughout the room every 15 minutes if desired. 1/4 fluid ounce (approx. 20 sprays from an ordinary trigger pump spray bottle) can be a good amount for a room 3.5 meters x 3.5 meters (12 feet x 12 feet).

Humidifier help

 

Run an ultrasonic humidifier to help destroy germs continually in the air and keep surfaces--such as clothing and furniture--disinfected wherever mist settles. The concentration needs to be lower than when using a spray bottle. Use our Chlorine Dioxide Solution Calculators to figure your desired concentration.

Place a room-size humidifier near people, but at least 1 meter (3 feet) away.

A mini ultrasonic humidifier can be held in your lap.

 

Note: A relative humidity of 40-70% is ideal for effective chlorine dioxide use. If you wish, you can buy an inexpensive hygrometer to monitor.
