The 5 Ws and 1 H of Environmental Disinfection

Updated: Sep 19, 2022


According to an article of an epidemiologist, environmental decontamination refers to the process by which environmental contamination is reduced to a level that is not harmful to health. Decontamination of the environment can be achieved through cleaning, disinfection, or a combination of the two.

Cleaning, disinfecting as well as sanitizing may all seem the same, but there is a difference among these terms. The Center for Disease Control and Prevention (CDC) notes the following:

Cleaning physically removes germs, dirt, and impurities from surfaces or objects by using soap (or detergent) and water. This process does not necessarily kill germs, but by removing them, it lowers their numbers and the risk of spreading infection.

Disinfecting kills germs on surfaces or objects by using chemicals, preferably disinfectants registered under the U.S. Environmental Protection Agency (EPA). This process does not necessarily clean dirty surfaces or remove germs, but by killing germs on a surface after cleaning, it can further lower the risk of spreading infection.

EPA-registered disinfectants are preferred and recommended because these are certified effective against a wide range of bacteria, viruses, and microorganisms. This registration is based on evaluation of scientific data and assessment of risks and benefits of a product’s use.

Sanitizing works by either cleaning or disinfecting surfaces or objects to lower the number of germs to a safe level and the risk of spreading infection.


COVID-19 is known to be transmissible between people when an infected person comes in direct or close contact with another person with less than 1 metre apart. When an infected person coughs, sneezes, speaks, sings, or breathes heavily, small liquid particles can be expelled from the mouth or nose and can enter another person’s respiratory system. These droplets can also contaminate surfaces long after the infected person is no longer around, which if you touch your face after touching the contaminated surface or object, it can also be a source of infection.

The coronavirus is vastly spreading in the Philippines resulting in an increased number of active cases every day which means the probability of contracting the virus is also surging. As of April 12, 2021, there are a total of 876,225 coronavirus cases in the country. While both indoor and outdoor locations are hazardous health risks, the World Health Organization (WHO) specifies crowded places, close-contact settings, and especially confined and enclosed spaces with poor ventilation to have higher transmission risks for COVID-19.

This highlights the importance of why we should keep our environment clean frequently especially at this time. The Virginia Department of Health states that microorganisms (bacteria, fungi, viruses) are present throughout our environment and can cause infection hence the environment can serve as a breeding ground for these organisms. It is vital to take preemptive health measures like full-coverage disinfection on establishments to contain the rapid spread of SARS-CoV-2 (coronavirus) on different surroundings.


CDC notes that cleaning high-touch surfaces should be a priority. The more people touch a surface, the higher the risk of transmitting COVID-19 from one person to another is.

It’s always better to make big efforts to secure the safety of people staying in a certain area for long periods of time. Doing so avoids the possibility of contracting various illnesses from person-to-person and spreading it from place-to-place.


The International Sanitization and Protection Suppliers (ISPS) is a licensed biomedical service provider that promotes environmental disinfection by administering misting and electro bio-fogging services. As the Philippines’ trusted partner against COVID-19, we take pride in our achievements such as providing a regular disinfection service at the four (4) largest testing and quarantine facilities in the country namely: the Philippine Arena, Palacio de Manila, Enderun, and MOA Arena. Ever since our founding, we have conducted more than 700 disinfection operations over a million square meters for multiple private companies in different industries all over Luzon. To name a few clients, they are: BPI, Ideal Vision, Novotel, and Punta Fuego.

Our highly-trained and certified staff take disinfection and sterilization to another level as we use modern technology combined with industry-leading techniques to ensure the effectiveness of our services, which are ideal for usage in residential, commercial, and industrial areas given today’s pandemic situation.



Multiple lockdowns, quarantine periods, and the global pandemic altogether caused a lot of companies to temporarily or permanently close down, halt activities, retrench employees, and cut down expenses. While some businesses are now operating on skeletal schedules and limited personnel, in order for them to do so, they should comply first with proper health protocols. This guidance list, as recommended by CDC, includes “routine cleaning and disinfection” as one of the main points in mitigating and preventing the spread of COVID-19 in the workplace.

ISPS helps agencies and corporations abide by government requirements to have their respective establishments regularly disinfected through the use of misting and bio-fogging services. Our clients in the corporate sector range from offices, spas, resorts, restaurants, factories, and more. We guarantee each and every one of them receives a certificate of disinfection.

We also pioneered a training program called “Equip Train Disinfect Protect” that aims to educate staff and employees on how to implement disinfection protocols specific to one’s place of business or industry. Our team of experts will provide all the necessary equipment and chemicals as well as the training so that workers will know how to disinfect on their own and companies will no longer have to hire contractors or sanitation agencies every time.

By purchasing the equipment and chemicals, the training can be done for free, however, if you are interested in just receiving the training, we offer our certified disinfection program for ₱15,000. Below are some of the modules covered in the program.

Since staying at home is the most recommended course of action to mitigate the spread of the virus, regular home disinfection is a must to make sure you’re safe even while at the comfort of your own home. This is especially encouraged for households who have family members working on site or people who constantly receive deliveries.

The culture of working or studying at home is also prevailing for the sake of keeping everyone’s health in check, which is why it is important to prioritize cleanliness at all times so you, your family members and/or relatives don’t get sick. For more health tips on how to do so, check this link.

A lot of private individuals have availed ISPS services for residential disinfection. Our sanitizing technique is capable of covering open and enclosed spaces like furniture and rooms (bedrooms, bathrooms, living rooms, kitchen, drawers, shelves, etc.) as well as exposed surfaces like tables, chairs, floors, walls, sofas, and more.

ISPS’ Test and Disinfect Promo is perfect for residential areas. Just simply book an appointment for either a mobile antigen swab test or a mobile polymerase chain reaction (PCR) test and with an additional ₱1000, you get a free home disinfection session that can cover up to 250sqm.



To further enhance the efficacy of our services, we only use the most powerful and safe disinfectant, in combination with industrial-grade equipment, to give clients the total ISPS treatment.

CDC made a point to “read the label” of disinfectants to make sure they are approved by the United States Environmental Protection Agency. EPA-registered disinfectants already have an advantage in the international market as they are classified as trusted and credible brands among consumers. Biotab7, with EPA registration number 91399-2, is ISPS’ sanitizing solution and is called the “COVID Killer” primarily because of its capability to kill the SARS-CoV-2 virus in just 60 seconds or less!

Our Biotab7 disinfecting mixture can reach areas that conventional cleaning usually can’t such as high ceilings, walls, and inner corners of certain spaces. It is non-corrosive and leaves no chemical residue so it will not damage or harm delicate materials or surfaces.
