Our world is currently dealing with a huge problem with COVID-19.
Not knowing if who we may be walking near is sick. Being constantly on edge about what germs we are being exposed to.
Having to have that tough talk with our children about what is going on with our health and how they need to adjust their lives in order to manage what’s this pandemic.
Despite all of this, the one place you should feel safe, is in your home.
But unfortunately, it’s very easy to bring outside germs in the house and then from there, it can spread extremely quickly.
According to the CFF (Cystic Fibrosis Foundation) and the CDC (Centers for Disease Control) germs can be spread by tiny droplets up to 6-12 feet just from someone sneezing or coughing.
It is also possible for these droplets to stay suspended in the air for hours at a time.
But, there’s a solution to keeping harmful germs and bacteria out of your air and it is having an air filter.
Air filters for your HVAC or AC system are extremely effective in cleaning your air from bacteria, fungi and viruses.
In this guide we’ll explain more about exactly why you need a filter and which type of filter you’ll need to significantly reduce the chances of COVID-19 infecting your household.
There are a number of different air filters that are on the market. With us being experts in this field of study, there are multiple reasons that we choose the MERV 13.
Minimum Efficiency Reporting Value and is an acronym that was designed by ASHRAE to create a scale that displays how effective the filters are at removing particles of different sizes.
There’s a range of sizes in the MERV that range from 0.3 µm to 10 µm and broken down into smaller ranges. This filter also is manufactured from 100% synthetic media which means that it is anti-microbial and able to offer more efficiency than normal poly/cotton media pleated filters.
The MERV 13 is able to capture microscopic particles, airborne dust, mold spores, viruses, pollen, dust mites, mold, smoke, bacteria and even pet dander.
This filter, when ordered with the added activated carbon is able to naturally deodorize the air by absorbing household odors that come from a number of sources including, cooking, garbage and bathrooms.
Being over 30 times more efficient than normal fiberglass filters at capturing micro particles allows the MERV 13 to perform significantly more than similar filters while still being able to maintain excellent air flow properties.
Merv ratings are tested through adding particles that vary in size (1-13) in a controlled environment. Laser particles then counter sample the air of the particles added upstream before it enters the filter and afterward, after it leaves.
The MERV filters that are the most efficient have a rating of 13 and above and are used and trusted regularly in hospitals and other clean environments.
Endorsed by HVAC professionals, the MERV 13 serves as the highest efficiency of air filter available while not overtaxing the HVAC system.
There is a 97.8% air efficiency when removing airborne particles that range from 3-10 microns in size.
An 84.1% efficiency in removing airborne particles that are 1-3 microns in size and a 60% efficiency in microns that are even smaller.
The MERV is also able to filter out aerosol droplets, which are able to carry COVID-19 viruses.
If you are looking for the best balance between HVAC efficiency and airborne particle remover ability, the MERV 13 is what we highly recommend.
Infections from viruses are shown to be reduced when using a Ultraviolet in conjunction with humidity control and airflow management. There are some attributes you need to consider before selecting just any UV. What should be considered is the type of lamp, airflow amount and mixing and the design of the fixtures.
While not generally regarded as an overall solution, air filtration that's in ventilation, air conditioning and building heating is a part of a larger overall risk mitigation.
It is required for a system to have to be installed and maintained in order to properly have an impact on potentially infectious diseases that are airborne.
Adding an Air Purifier in addition to using MERV 13 HVAC and AC filters assists in providing protection from COVID. There are 3 main filtration methods that air purifiers use to clean air and they are HEPA devices, ozone generators and activated carbon filters.
Some ionic purifiers work by creating ionized particles that are easily attracted to surfaces that are within the air filter which essentially removes them from the air.
The ones that need frequent cleaning are usually the ones that have a plate to collect the ionized particles.
Other types of filters have previously had problems from producing ozone but the minimum standard of how filters should perform has been significantly raised over the years.
To be sure that purifiers are performing to the standard, there are now third-party firms that test to make sure they do not release ozones.
You should always follow the Center for Disease Control and Prevention (CDC) guidelines when you think someone in your house is sick. This is the first step to making sure that the disease can be contained.
Since being in close contact with someone is the main transmission route for COVID the best method of using an air purifier to reduce the spread would be to place the purifier three feet from the person who is sick and run it for 24 hours a day.
Also keeping the air purifier away from other objects that can block airflow is vital.
When it is time to change the filter, you should safely do so wearing gloves and a mask. Thoroughly cleaning the air purifier when replacing the filter is desirable and wiped with disinfectant and the old filter sealed and thrown away.
Make sure to stay consistent with changing your filter so the air purifier can continue to function as efficiently as possible.
If you’ve made it to the end of this guide, you already know that the MERV 13 is our top choice for the best air filter for COVID.
Having an air filter can greatly reduce the amount of pollutants that are in the air and help keep the inside of your home’s air much more clean.
Regardless of whether you have an air purifier or not, you should always follow the CDC guidelines for COVID and keep a safe distance away from others when required.
Doing the small things like washing your hands more frequently and covering your mouth when you sneeze and cough can reduce the amount of germs that are spread throughout the household.
