What is An Air Purifier?

First, let’s answer the question what are air purifiers?

An air purifier, also known as an air cleaner, is an electronic device that aims to clean the air by eliminating harmful air contaminants, such as particles that could potentially harm your health or that of your loved ones. Despite the fact that you may have heard about air purifiers before, you may not know exactly what they are or what they do.

Air purifiers are highly beneficial for you and your family’s health, but before you can enjoy their benefits, it’s essential to familiarize yourself with their function. These electronic devices are designed to purify the air by removing air contaminants, which are particles that could cause harm to your health or those who visit your home. It is highly recommended that all households have an air purifier, and some homeowners are even urged to get one.

Individuals who have pets or in-house smokers are often urged to get an air purifier, as studies have shown that pets and cigarette smoke can cause unhealthy air particles to form. In addition, those who suffer from allergies or have pets should consider purchasing an air purifier as it can eliminate common dust particles, which are a common cause for allergies. An air purifier may also help to reduce allergic reactions to pets or pet hair by keeping the air clean.

Different manufacturers produce air purifiers in different ways, and as a result, different purifiers work in different ways. However, most air purifiers use ionizers and filters to eliminate harmful air particles by preventing them from passing through the system. This ensures that only safe, clean, and breathable air is allowed to pass through.

Can Air Purifier Remove COVID Virus?

While there’s no scientific backing, that air purifiers can prevent COVID 19 or remove the COVID 19 virus it still stands to reason that we can protect ourselves from this deadly virus by reducing air pollution since according to the WHO, “exposure to high levels of air pollution can cause a variety of adverse health outcomes.”

The CDC (Centers for Disease Control and Prevention) was also quoted by the United States Environmental Protection Agency (EPA) as saying,

“Operating an air cleaner can be part of a plan to protect yourself and your family.” Furthermore on this the EPA said: “Ensuring proper ventilation with outside air can help reduce indoor airborne contaminants, including SARS-CoV-2, the virus that causes COVID-19, and other viruses. However, by itself, increasing ventilation is not enough to protect people from exposure to the virus that causes COVID-19. When used along with other best practices (such as wearing masks, social distancing, frequent hand washing, and surface disinfection) recommended by the CDC, increasing ventilation can be part of a plan to protect yourself and your family.”

From the above it stands to reason to say that getting an air purifiers can help with COVID-19.

What Air Filters Protect Against COVID?

If you’re looking for the best air purifier for COVID 19 you will need to be careful because most of the products that claim to be the best are far from being that.  However, from various customer ratings and researches, HEPA air purifiers have been found to be the best for viruses and COVID 19.

Please note that HEPA is not a brand name of any product. It is the technology used in manufacturing air purifiers. It stands for High Efficiency Particulate Arrestor (HEPA). This technology is used in the manufacturing of air purifiers, air cleaners, vacuum cleaners etc.

Some HEPA technology air purifiers are available with the EGF (Enhanced Germ Filtration) system or ultra violet system. The machines are medically graded and are equipped with advance technologies, are efficient in destroying the impurities like pet dander, pollen, viruses and any other impurities that might trigger the chances of breathing disorders, at quicker and a faster rate. 

The filters of the higher range of these purifiers contain Zeolite and activated blends that work effectively in absorbing the chemicals or the gases released in the office indoor or in homes. The filters of the lower range of these purifiers, which are built with HEPA technology, are just covered with carbon dust come with a very short period of life/ usage and are not effective against cleaning and purifying of the air.

These filters have been found to be effective in making the air pure up to 99.97 % and they can filter air particles as minute as 0.3 microns. And since the virus that causes COVID-19 is approximately 0.125 micron (125 nanometers) in diameter it therefore means that HEPA filters can effectively capture them.

Of course, many people still believe that HEPA filters don’t filter below 0.3 micron and therefore will not be able to capture airborne coronaviruses. However, a study by NASA shows that HEPA filters are actually most efficient—almost 100% at 0.01 micron—at capturing ultrafine particles below the 0.3-micron HEPA test standard.

So getting a HEPA air purifier is definitely a good investment in protecting your family against the COVID 19.  However, you must note that as the CDC writes: “The best way to prevent illness is to avoid being exposed to this virus.” So even if you decide to use an air purifier as a protective measure, we recommend that you also continue to closely follow the CDC’s other longstanding advice.

What to Consider when Shopping for Air Purifiers

When searching for air purifiers online, you’re bound to come across a variety of options. While each air purifier has its unique features, one common aspect is their capacity to clean a specific space. Most air purifiers are designed to handle a small area, typically around 200 to 350 square feet. However, it’s possible to find air purifiers that can work in larger or smaller spaces.

Now, you may be wondering if an individual room air purifier is worth investing in, considering its limited coverage area. Well, it depends on your preferences and needs. If you have a room where smoking or pet activities take place, a single-room air purifier may suffice. However, if smoking or pet activities occur throughout your entire home, then you should consider getting a whole house air purifier.

Individual room air purifiers come in various shapes, sizes, and prices. Some cost as little as $50, while others may cost up to $1,000. The price generally reflects the quality of the product, with the better performing ones costing more. However, the higher cost may be justified by their superior performance and longer lifespan.

Before making a purchase, it’s crucial to measure the size of the room to ensure that the air purifier can effectively clean the air inside. If the air purifier’s maximum square footage is smaller than the size of the room, it may not work correctly. Also, consider if the room has a door, as closed doors can produce better results.
