The Covid-19 pandemic will go down in history books as one of the most devastating events of the century. We cannot remember the last time that most schools and places of worship were closed indefinitely. The World Health Organization has come up with guidelines that will help curb the spread of this deadly virus.

Staying home for those who can, social distancing, washing hands, and sanitizing are some of the phrases that we may have to put up with for a little bit longer. Research shows that the virus that causes Covid-19 is caused by close contact with people who have contracted the virus. It is also evident that the virus can survive in the air for more than half an hour before it settles on other surfaces. Can the best air purifiers for your home protect you from Covid-19? This is a question that is troubling many people at the moment.

How air purifiers work

Research indicates that indoor air is 2-5 times dirtier than the outdoors. Air purifiers come with a system of internal fans that pull through a series of filters. These filters remove harmful airborne particles such as pollen, dust, viruses, and bacteria. The air purifier will then circulate the purified air back into the house and make it safe for survival. This process will be a cycle as long as the air purifier is turned on.

Why you need an air purifier in your home

Remove unpleasant odors

There are a lot of things that can bring bad odors in your house. Think about that fish that you often cook in your home. You may also have used various cleaning substances that leave a nasty smell in your house. Your house may also be damp during the cold season. Your kids may have spilled liquids on the carpet or your couch, leaving bad odors. All these odors may never go away even after a thorough cleaning exercise. If you need to deep clean your office, we recommend getting in a Coronavirus cleaning specialist. An air purifier will help clean the air and make your house fit for survival.

Traps dust

There will always be dust in your home, no matter the cleaning approach that you take. Dust causes various respiratory illnesses and makes your home unfit for habitation. An air purifier traps dust before it settles on various surfaces. It thus protects your home from dust built up, which means that you have less dust to clean at the end of the day.

Your lungs will get healthy

The lungs are among the most important organs in your body. They also among the most delicate. Constant exposure of your lungs to allergens, pollen, dust, and dander, will make them suffer. You may not feel the effects of these particles instantly, but you may suffer in the future. Consistent use of an air purifier system in your home guarantees you that you will have healthy lungs into the foreseeable future.

Air purifiers in shopping malls

This pandemic has led to the closing of many malls all over the world. New York is one of the states in the US that has bit hit hard by this virus. Its governor, Andrew Cuomo, issued a directive where major malls were to install “air filtration systems that will filter out the virus” before they reopen.

Researchers are on their toes as they tried hard to learn how this virus is transmitted from one person to the other. Aerosolized particles and droplets from a person that has contracted the virus have so far proven to be the most common modes of transmission of this disease.

Air purifiers and viruses

The risk of infection is very high in enclosed areas such as offices, restaurants, and any other places with low ventilation. Experts are proposing that resuming indoor activities should only happen when there is enough ventilation in such areas. People are focusing on cleaning surfaces, but it is also important that we ensure that the air we are breathing is clean. Effective ventilation cleans the air through recirculation and, at the same time, filters outs harmful substances.

Can HEPA technology help?

The UK has the highest number of Covid-19 related deaths. The high-efficiency particulate air filters (HEPA) have drawn the attention of various players in the fight against this virus. These filters can remove about 99.97% or particles, which are .3 microns or bigger according to research done by the United States Environmental Protection Agency. Most droplets that carry viruses that are known to cause diseases are in this range, which is a great discovery in this fight.

The virus that causes Covid-19 has a diameter of about 0.125 microns (125 nanometers). Does this fall in the range of particles that HEPA filters can capture? According to a study conducted by NASA, HEPA filters can capture particles that are 0.01 micron (10 nanometers) and above, and that is where coronaviruses fall.

However, the performance of the filter will depend on its Minimum Efficiency Reporting Values (MERV). The MERV ratings range from 17-19. The lower the MERV rating, the lower is the effectiveness and efficiency of the HEPA filter in eliminating pollutants that may cause diseases.

Air purifiers are not enough

Different bodies such as WHO, NHS, and CDC have illustrated that Covid-19 is transmitted through droplets that are expelled through sneezing and coughing. We can thus not consider HEPA filters and air purifiers as the first line of defense against this deadly virus.

You must determine if there are viruses or particles to be filtered before you come into a conclusion on their effectiveness. It is still unclear if a HEPA filter will catch the virus before it hits the point of infection. Research is also yet to determine the level of exposure to the virus that will cause an infection.

We can only conclude that air purifiers will be marginally useful in fighting Covid-19 and that people still have to follow other measures that have been set up by various experts in the health sector if we want to win the fight against this virus.
