What is Ozone Purification and How Does It Work?

by OSHINER 2021-06-15

“What is that smell!?” or “Where is that smell coming from?”

These phrases have been much too common in my household. Depending on the room in the house, the culprit was always different. Sometimes it was a stale water smell in the washroom, others times the compost smell coming from the kitchen. Despite my best efforts, sometimes it was me having a secret cigarette break in the laundry room. Whatever the case, the unwanted smells were often easy to notice and often commented on.

I have tried everything to mask or “get rid of“ the smells, but nothing has ever proved to be 100 percent effective. Air fresheners always just masked the smells instead of eliminate the smell as advertised. Cleaners like chlorine or vinegar have worked for a short time, but then your left with the equally as strong and unpleasant smell of the cleaner, plus the first bad smell would always return eventually. I was about to just give up and learn to live with these smelly smells, accepting them as part of the room they occupied, and a part of my life.

That is when I found Oshiner’s Mini Air Purifier. Not only did it get rid of the smells, it also got rid of other dust in the air, making each room smell cleaner and more fresh. What I loved most was how simple it was to use! Finally there was no more need to go to buy multiple cleaners, air fresheners, refills, filters, in the hopes that it might clean the air and get rid of the bad smell. Oshiner’s Mini Air Purifier is the perfect all in one appliance that really works. Just plug it into a normal house outlet, press the start button, and it starts making ozone to get rid of odor, dust, bacteria and viruses, leaving the air smelling and feeling amazing! The best part is that it has a built in timer, so it will automatically turn off after 30 minutes which is perfect.

I wanted to know exactly how ozone worked for purifying the air, so I did a bit of research and I was surprised at what I found.

What I found is that ozone is a molecule made of three oxygen atoms. Normally the oxygen we breathe is made up of two oxygen atoms, shown as O2, so to make ozone, the oxygen in the air needs to be split apart, usually using an electric current of some kind. This gives the oxygen the ability to reform as ozone which is shown as O3. Oxygen atoms prefer to make basic oxygen (O2) rather ozone (O3) which makes ozone a bit of an unstable molecule.

Because ozone is considered unstable, it wants to stick to other molecules in its area, such as smoke, bacteria, viruses, fungi, dust and other pollutants. This makes it ideal for sticking to, and protecting my family from bad smells, common colds, the flu during flu season, and other serious airborne viruses! There is also no signs that viruses, bacteria or fungi can build an immunity to ozone disinfection, meaning it will keep effectively working and cleaning for days, weeks, and years to come.

I have also came across some possible hazards that should not be ignored when using ozone in the home.

Some of those hazards being, high expose to ozone can be dangerous for certain groups of people, especially those with asthma causing chest pains, difficulty breathing, throat irritation or even infection. Because of this, both the OSHA (Occupational Safety and Health Administration) and NIOSH (National Institute of Occupational Safety and Health) recommend an upper limit of 0.10 ppm of ozone not to be exceeded.

Of course after seeing this I became concerned that maybe using ozone to purify the air in my home was not the right choice. I was quickly reassured when I seen that Oshiner’s Mini Air purifier is made to not exceed the recommended 0.10 ppm of ozone, and also has an automatic shut off timer to limit ozone concentration and also save energy.

Now, because ozone is highly unstable, it also has a half-life or lifespan of about 30 minutes. After that time it will break down and the oxygen atoms will find a new bond to make. This means ozone is safer to use because it does not leave any residuals like other cleaners such as chlorine.

Also because of its half hour lifespan and inability to be stored because of its instability as a molecule, ozone must be made as it is needed. This made sense as the reason why ozone is produced from an appliance like Oshiner’s Mini Air Purifier, and it did not come in a can like many other so-called ‘air fresheners’.

I am incredibly happy with my new Oshiner’s Mini Air Purifier, and after learning how ozone works to disinfect and purify the air in my home, I am confident that I have made the right decision. It works when I want it to, turns off automatically, and applies just the right amount of ozone in the air to keep me and my family safe from viruses, bacteria, fungi and bad smells.

I highly recommend everyone using Oshiner’s Mini Air Purifier in their home too! Give it a try and I know you will be impressed with the results. Start breathing cleaner air today!

Play Your Role in Reducing Food Waste

by OSHINER 2021-05-28

Every day, tons of food go to waste worldwide and a significant portion of it, is still perfectly edible. It is estimated that almost a third of the world production is lost or wasted every year. You might think that it does not affect you and that there is little to nothing you can do about it, but the truth is food wastage affects you directly. In all this, you also have an important role to play to stop it.

Did you know when food is discarded, it is sent to landfills where it rots and generates both greenhouse gases (such as methane which contributes to climate change) and leachate which infiltrates soil and water sources and is responsible for safety and health hazards?

Wasting food wastes the resources that went into producing that food, from the water, seeds, feeds to labor, effort, energy, and investment. This problem finds it roots at each step of the journey of the food that ends up on your plate, and even after, if it is thrown away. In fact, the responsibility is shared at three different levels: farmer level, retail/business level and consumer level. More specifically, food gets spoilt during harvesting, processing, transportation, storage in warehouses and supermarkets… and when stored for too long in our homes. And between 20 to 40% of fruits and vegetables are disposed off when marked, discolored, or oddly shaped and sized because they do not meet the standards of the marketplace.

Reducing food loss and waste is essential for a sustainable future of the planet and every action counts. At an individual level, there are simple things we can all do to reduce the quantity of food that goes to waste in our homes.

– Starting with planning weekly meals, you will save money and time and eat healthier food. By doing so, you will stop buying food on impulse at the grocery store and only get what is necessary for a week.

– Secondly, note upcoming expiration dates on foods you already have at home, and plan meals around the products that are closest to their expiration.

– Thirdly, store foods the right way, put perishable foods in the refrigerator or freezer as soon as you get home from shopping, and store all unopened non-perishable products in a clean, dry place at room temperature.

– Fourthly, buy funny-looking fruits and vegetables, do not discriminate against “ugly” fruits and veggies.

– Lastly, shop from your refrigerator first! Cook and eat what you already have at home before buying more.

Engaging in food safety and preservation has a big role to play in solving the food waste problem. And one attractive alternative to resolving the issue is the use of ozone technology for food preservation. In fact, ozone is already applied in the food industry in developed countries, as a sterilizer for food and as been granted with the status of “Generally Recognized As Safe” (GRAS) as a sanitizer and disinfectant for foods by the FDA.

Ozone application for food preservation is considered a safer and greener alternative than traditional technologies, mostly because ozone application is non residual and does not affect the taste or smell of food products. Ozone is often spread on fruits and vegetables to prolong their life and reduce their wastage, but it is also applicable on red meat, poultry, seafood, dairy, spices, nuts, and frozen foods.

Ozone can also be used by households to preserve and safely stored their food. With Oshiner Fridge Freshener, you can now prolong the lifespan of the food you store in the fridge.

With Oshiner Ozone Fridge Freshner, you can keep your food two times longer through the preservation power of ozone. With its oxidation and elimination of bacteria and viruses, ozone preserves your food fresh longer while killing off the germs present in your fridge. Keeping your fridge sterilized and your food fresh and free from bacteria, avoiding unnecessary food waste.

Play your part in stopping food waste by patterning with Oshiner.

Ozone Applications in Air Treatment and Disinfection

by OSHINER 2021-05-17

Ozone is an inorganic molecule also referred to as activated oxygen because it is composed of three atoms of oxygen bound together. It is generated by stimulating a flow of oxygen from ambient air, with high energy amounts and causing the atoms of oxygen to split and reorganize into new molecules, oxygen free radicals and O3 (ozone). More than a 100 industries daily use ozone in countless applications. From water treatment to manufacturing processes, equipment maintenance, odor treatment, and preservation of food and raw materials.

Air Disinfection

Usually in the form of a gas, it is largely used as a disinfecting agent because of its strong oxidation abilities. When it comes in contact with bacteria, ozone breaks through the cell membrane and neutralizes the bacteria’s essential components (RNA, DNA, enzymes and proteins) leading to its destruction. Not only is ozone a disinfection agent, it is also categorized as a sporicidal agent (kills spores), an algaecide (kills and prevents the growth of algae) and a virucide (destroys or inactivates viruses).

Log reduction Values

Log reduction mathematically expresses the relative number of cells killed in a disinfectant test

For most applications, a log reduction of 4 is sufficient on average. Since ozone is produced on site, there is no extra cost for handling and storing dangerous chemical substances. And ozone does not leave residue after treatment as the atoms of ozone O3 decompose back to oxygen O2. The gaseous spread of ozone allows to disinfect any surface and reaching out difficult spots. Be with low or high concentrations, ozone is able to kill bacteria, viruses and spores.

Biological Lethal Coefficients of Common Disinfectants

Disinfectant	Enterobacteria	Virus	Bacterial Spores	Amoebic Cysts
O3	500	5	2	0.5
HOCL	20	1	0.05	0.05
OCL	0.2	<0.02	<0.0005	0.0005
NH2CL	0.1	0.0005	0.001	0.02

*BLC: high value= high disinfection power

Hospital

The use of Ozone is very appropriate for medical applications as it is more effective to sterilize large air volumes (like waiting rooms or treatment rooms) from bacteria and viruses compared to other air treatment alternatives. Ozone sterilization is good to preventing the spread of germs and pathogens in patient rooms by cleaning before and after new patients come to the rooms. And certain areas such as corridors, waiting rooms and bathrooms can be scheduled for ozone disinfection at nighttime, when they are free of patients and employees to allow the disinfection enough time to thoroughly sanitize the area. For rooms requiring a 6-log scale deactivation of living microbes like surgery rooms, the solution is to apply and monitor high concentrations of ozone in that room when closed, for many hours, letting the ozone disinfecting the area and paying close attention to the recommendations about exposure time.

Food storage

One of the industries in which ozone is used the most is the food industry. In Oshiner previous article Ozone Applications in Water Treatment and Disinfection, we explained the disinfecting use of ozone in the food and beverage industry. Now we would like to talk about another application of ozone in that industry.

Ozone is vastly applied in the process of food storage as a gaseous fumigant. Starting in the pre-packaging stage of production of certain products such as meat and poultry, and the storage of directly harvested products, like potatoes, ozone is utilized to extend the shelf life of the products by reducing bacteria levels and controlling the spread of different pathogens. By eliminating the bacteria that cause the food to rot, ozone treatment allows to storage of harvested products for longer periods.

Odor Control and Smoke Removal

With the expansion of urban populations into industrial areas, odor control has rapidly become one of the most discussed topics within industrial environmental concerns. This situation is forcing businesses to consider the problem of odor pollution emanating from their factories. With its oxidation power, ozone has proven capable of eliminating different kind of industrial odors with a careful application custom-made for specific odors.

The same goes for ozone application on smoke. It can effectively break down the smoke molecules and separates them so that they can disperse, removing the room odor and smoke, and considerably making the area treated more comfortable and pleasant.

Safety Measures

When operating an ozonator, it is important to know what the recommended concentration levels of ozone are. Generally, any level below 0.1 ppm is considered non-symptomatic, but higher concentrations can be tolerated. For example, exposure levels up to 1.0 ppm can be non-symptomatic, but only for up to 10 minutes. The 0.1 ppm point seems to be the accepted tolerance level.

In fact, the Occupational Safety and Health Administration (OSHA) standard is 0.1 ppm for a maximum of eight hours in the workplace. Anything beyond that level and, depending on exposure time, may cause symptoms including eye, nose and throat irritation, coughing, headache and shortness of breath.

OSHA has set specific guidelines for using ozone in the workplace and based on time-weighted averages. Ozone levels should not exceed the following standards: 0.10 ppm (parts per million) for an 8-hour work shift:

• 0.2 ppm for no more than 2 hours exposure

• 0.1 ppm for 8 hours per day exposure doing light work

• 0.08 ppm for 8 hours per day exposure doing moderate work

• 0.05 ppm for 8 hours per day exposure doing heavy work

Despite some concerns and warnings about exposure to high levels of ozone, the number of air treatment applications using ozone technology has increased significantly in recent years. Whether for public spaces disinfection, food storage or industrial odors control, ozone is proving to very useful in various industries.

2021 Top 5 Used Technologies in Air Purifiers

by OSHINER 2021-04-30

As a society, we are progressively becoming more and more conscious of what affects our health. Caring for the quality of the food we eat, the water we drink, the clothes we wear and even the air we breathe. It probably explains why home-care appliances such as air purifiers have gained a lot of popularity these recent years. Let us briefly explore together the different types of technology used in air purifiers.

HEPA

High Efficiency Particulate Air (HEPA) is the most popular filtering media used in air purifiers and works by trapping in its meshed structure, the particles present in the air. HEPA removes 99.97% of particulate matter of size less than 0.3 microns, like the dust and pollen in the air that cause allergies. But if the filter is not frequently changed, it can create secondary air pollution because of accumulated pollutant that generate more bacteria and mold. It is also important to note that a higher grade HEPA filter is not necessarily the better. This is because the higher-grade the HEPA filter is, the more compact it become, capturing more particles but allowing less air to flow through. Read more about it in our previous article:How to choose HEPA filter, H11, H12 or H13?

Activated Carbon

Activated Carbon or charcoal is a natural absorbent usually used to filter out smells, smoke and odors present in the air by physical and chemical absorptions. Mostly used as an indoor deodorizer, it is relatively cheap and accessible making it very popular. Activated carbon is not used as a standalone air filter because it does not trap allergens and certain pollutants, and requires frequent replacements because it gets saturated with contaminants rapidly.

ESP

Electrostatic Smoke Precipitators (ESP) are electronic air filters working on the principle of corona discharge, removing particles from contaminated air by positively or negatively ionizing them using electrical energy. Then the charged particles are attracted to collectors plates of opposite charge and extracted as dry material (dry ESP) or washed off with water from the collector plates (wet ESP). ESP is capable of removing any sized particles from dirty air but it requires high energy input thus higher energy cost.

UV-C Radiations

Ultra Violet germicidal irradiation or UV-C is emitted to inactivate airborne microorganisms and pathogens present in the air, such as bacteria, mold and viruses. According to its wavelength, UV-C requires more or less time for irradiation to disinfect thoroughly the air against bacteria. But more time, higher numbers are not necessarily the best. With wavelength varying from 200nm to 280nm, the UV-C radiation effectiveness depends exposure time and the type of bacteria it is fighting. To know everything about that, check out our article: Do you know how long does UV lamp take to disinfect?

It is important to remind you that following recommendations and security measures is important to guarantee your safety when using UV-C products because temporary exposure to ultraviolet light can damage your skin and eyes. So stay safe and always wear safety glasses and gloves.

Ozone Generator

Ozone or Activated Oxygen (o3) is one of the most spread disinfection methods used in industries. It is produced using UVC tubes or corona discharge and is used to destroy microorganisms and eliminate spores and viruses. Ozone is also very efficient to neutralize odors, bacteria and germs. We might assume that the most concentration of ozone guarantees the best disinfection but this is not true. Not only that but this can be dangerous. Hight level concentrations of ozone are harmful of your health directly affecting the lungs and respiratory system. Ozone disinfection done right demands proper monitoring that can be achieved with time control.

Ozone Applications in Water Treatment and Disinfection

by OSHINER 2021-04-14

When we talk about “ozone”, we generally have in mind the ozone layer that covers the Earth’s atmosphere and protects its surface from ultraviolet rays. But ozone is also a component long mastered by men, that has proven useful in numerous applications. Although controversial, ozone has been used in different industries over time, and has in recent years gained market for domestic use. Let us take a look at different ways ozone is used in for water treatment and disinfection.

Disinfecting Properties

Water Treatment

Ozone is often used in water treatment as a disinfectant. One of its main advantage is that it does not leave residues or byproducts after its application. In normal water, the half-life of ozone is from 10 to 20 minutes while in wastewater, ozone disappears after 9 seconds because it reacts to the particles and debris present in the wastewater. The use of ozone for disinfecting water reduces the need for chemical involvement and spending cost. Ozone is used to treat drinking water, industrial wastewater, it is also used for treatment of cooling towers, for ground water remediation and even in the hydraulic fracturing (fracking) industry among other things. Ozone is also effective to remove colors and bad odors from ground water and wastewater.

Food and Beverage Industry

The second prominent use of ozone is found in the food and beverage industry. Ozone eliminates germs and bacteria the moment it comes in contact with them. Since it can be produced on site, it is a good alternative to other disinfection and sterilization methods. The particularity of ozone is that its application is non residual and does not affect the taste or smell of food such as dairy products. And its oxidation is applied on fruits and vegetable to prolong their life and reduce food production waste. In addition to treating water and food, ozone is utilized to sanitize and sterilize food plants surfaces and equipment.

Oxidation of metal

When they are not oxidized, metals such as iron are quick to pass through mechanical filtration and end their course in water sources. Once there, it is a difficult process to remove them from these waters. So to avoid this situation, oxidation before filtration is necessary for such metal. But the use of traditional oxidizers such as permanganate are costly, residual and have to be closely monitored while with ozone, the oxidation time is quicker at a low dosing. Not only is ozone as effective but it is also less costly.

In the recent years, ozone has proven to be an efficient alternative to numerous commonly used chemicals in water treatment. Used as a disinfectant or oxidizer, it is a very practical element that is making its way into domestic use through portable ozone generator devices. But is water treatment the only domain of application for ozone? To answer this question do not forget to check out our future article part 2, ozone application in air treatment.

Sadly, taking care of the house is still a woman’s job!

by OSHINER 2021-03-12

With this week’s celebration of the International women’s day, we are reminded of two things. The first is the remembrance of all the social, political, economic and cultural achievements of women in our societies and the second is the continuous fight for women’s right and gender equality in the world.

With the restructuring of our societies views on genders and their subsequent roles and parts, firstly in the family setting and secondly in society as large, what have become of the expectations society has on women, more specifically when it comes to managing the house? Going further in that direction, we cannot refrain to ask the question: Is taking care of the house still a woman’s job?

Numbers don’t lie. Even while working part-time to full-time jobs, women mostly take upon themselves household and familial responsibilities. With 15.12 hours spent weekly on housework for women compared to a 9.73 hours for men, women are still doing most of the work when it comes to taking care of the home in the US (1). Now, depending on where you come from these numbers may vary but this observation remains constant.

Our purpose is not to shift house chores and cleaning responsibilities to one side, but how do we share the burden between the two.

Even though nowadays people can be so sensitive when we discuss gender, there is no excuse robbing each and everyone of us of our basic responsibilities. House chores and cleaning are everyone’s responsibilities and should not be gender based and if you think they must be, you probably need some help.

We live in a world of balance, tip towards one side and imbalance is what you get. The family setting is one great example of where this concept of “balance” plays a role. For example, we can all agree that a child needs to be raised. Whether this is done by both parents or a single parent. Of course, it is always best if both parents participate. The idea here is in the raising of the child and instilling values in him/her that will impact his community positively even when you as a parent are long gone.

Same with cleaning, your home (bought or rented) is likened to a baby that constantly needs looking after. Now who does the cleaning of it (man or woman) is not necessarily the main point but why we should keep these places clean. And of course, it’s always best if both participate in the cleaning.

Now that you understand my point, being hygienic and being able to keep your house clean, for the various benefits is far more significant than who does it.

Let us take the family setting of a husband and wife, since I can’t speak for the boyfriend and girlfriend that decided to cohabitate but have not committed themselves to each other for a lifetime. And yes I can see you already collecting stones to throw at me, but be of good cheer, this is no big deal.

So, for the married, cleaning and doing house chores together has been mentioned to be one thing that strengthens the bond of love between partners.

If your wife is tired or under the monthly order of things, under visitation let us say, please sir, by all means clean the house, wash those dishes, cook that quick meal you happened to have stumbled upon on YouTube. Loving your wife is shown in the small things that improve her health and your family’s. Women, the same goes out to you. (And all the men and women applauded.)

In this pandemic, there is no questioning the importance of home cleanliness, as many people are working remotely from home and as we are now spending over 80% of our time in doors, surrounded by the ones we love.

There is so much that we would love to write but my word count will not permit me. In conclusion, chores are not based on gender. Man or woman, keep your house clean for the sake of your loved ones. Do not run away from this basic responsibility.
