When used properly, air cleaners and HVAC filters can help reduce airborne contaminants including viruses in a building or small space. By itself, air cleaning or filtration is not enough to protect people from COVID-19.
Although air purifiers can help lower the levels of airborne contaminants, they are not enough to effectively filter the air in a home or a confined space. Doing so should be part of a regular home cleaning routine.

How Air Purifiers Help with COVID
Since the pandemic began, people have been told to wash their hands a lot to reduce the spread of the disease. But, in the days following the pandemic, the focus has shifted to the air.
An air purifier can help minimize the spread of COVID by filtering the pollutants that enter the atmosphere.
The particles of the virus that are emitted as people speak and sing are aerosols and droplets that can be filtered out through a special unit.
How Effective Are Air Purifiers Against Covid?
The coronavirus is considered one of the most effective components of a HEPA filter. But it can still be neutralized by a high percentage of viruses, which can be achieved through prolonged exposure to ultraviolet light.
Your home is the safest place to be during the COVID-19 pandemic. In most cases, most people do not need air purifiers because they generally follow good social distancing practices.
Having a COVID-19 air purifier in the home is also helpful for minimizing the spread of the coronavirus.
However, it is still important to consider the safety of household members who are at high risk of getting sick from the virus.
By itself, air cleaning and filtration can’t remove airborne contaminants such as COVID-19 from a building or a small space. In addition, performing other precautionary steps such as wearing a mask and social distancing can help minimize the spread of the virus inside the home.
Air cleaners and HVAC filters are devices that help remove airborne contaminants from the air. They can also help lower the number of particles that enter the atmosphere. Portable air cleaners are usually used when air quality is not as good as outdoor air.
An air cleaner must be able to remove particles smaller than 0.3 um in order to effectively remove viruses from the air. This means it should be able to perform a particle removal efficiency of at least 99.9%.
To determine the effectiveness of an air cleaner, consider the model’s rating and the type of filter it uses. Also, check its size and other features to see if it fits in a given space.
Types of Air Purifiers that Can Help with Covid
There are a variety of air cleaners and purifiers on the market, but most of them require a filter to effectively remove COVID-19. Aside from COVID-19, a good filter can also help remove other harmful particles such as dust and mould.
A clean air delivery rate, or CADR, is a metric that measures how much air a filter produces.
The CARF is calculated by taking into account the air flow and filter efficiency of a machine. It does so by comparing the efficiency of different units.
For a smallish room, you want a filter that’s around 200 or bigger. For a bigger room, you want a filter that’s around 400 or 500.
There are also air cleaners that use other technologies than traditional filter components. One of these is called a plasma air cleaner.
There are also air purifiers that feature UV technology. However, according to Siegel, most of the time, UV units are just not powerful enough to effectively remove harmful particles.
Can HVAC Filters Help with Covid?
Air cleaners are used to remove airborne pollutants from a room or area. They can also help keep the air in a home cleaner by filtering the air throughout the house.
Although these products can help protect people from the coronavirus, they are not enough to effectively filter the air in homes. Instead, they should be used along with other strategies to help keep the people from getting sick.
Do air purifiers help protect against viruses like COVID-19?
In 2020, COVID-19 caused over 50 million people to get sick. It also contributed to the deaths of over 1.5 million individuals.
Aside from being effective at filtering the air, air purifiers can also help protect people from getting sick by helping prevent the transmission of viruses.
What is CADR in an Air Purifier?
The concept of CADR is the amount of particles that are removed from the air by a purifier. For an air purifier’s test, the contaminants are placed in a test space that measures about 1,008 cubic feet. The test conditions are then turned on for a short time to remove the remaining pollutants.
Although it’s important to test the performance of air purifiers for the first few minutes of operation, most of them eventually lose their efficiency after around 8 weeks.
The performance of a CADR test only measures the amount of particles that can be removed during the first 20 minutes of operation.
An air purifier that has been certified to filter particles smaller than 0.3 microns will have a higher efficiency.
How to Reduce Covid Risks by Using Air Purifiers
Both experts stress that air purifiers can help reduce airborne transmission, which can include keeping a sick person away from the public areas and the rooms where they work.
However, they also caution that incorporating an air purifier into your home may not do enough to prevent COVID or minimize airborne transmission. For instance, if you regularly use a filter, it might not do much to reduce your chances of COVID.
However, if you have an individual who is staying in a different room of your house, running an air purifier can help minimize airborne transmission.
If a family member is infected with COVID, then it’s possible to install an air purifier in their home to isolate the area where they live.
How Does an Air Purifiers Capture Covid Virus?
HEPA filters are very effective at capturing 99.97 percent of airborne particles. They do this by filtering out specks that are less than 0.3 microns in diameter.
The coronavirus is composed of about a thousand tiny droplets. They’re easily captured by filters with a diameter of less than 0.3 microns.
The volume of air that a machine can clean depends on the rating it gets from the Clean Air Data Registry. For instance, a machine that can remove pollen and smoke should have a 3C rating.
A smoke filter with a CADR of 250 will reduce the concentration of smoke particles in the air to the same level as adding 250 cubic feet of clean air.
Based on the tests conducted by Consumer Reports, we recommend looking for a machine with a CADR of over 240 to get the most out of its air. It can perform around five air exchanges per hour.
Since air purifiers can be loud, they can disturb a person’s sleep. In our tests, we found that some models can remove particles at lower speeds.
Even the most effective air purifiers can’t prevent droplets from landing on surfaces. To prevent the spread of diseases, people should regularly wash their hands.
Bottom Line
Air purifiers are not the first line of defense against airborne viruses. They can also help prevent the spread of infections through the use of CADR.
Although an air purifier can effectively filter viruses, they can also contribute to the spread of airborne viruses.
Unfortunately, air purifiers can’t prevent all airborne viruses from spreading. They can only help remove pollutants and limit the spread of pathogens.
Unfortunately, air purifiers can’t prevent the transmission of airborne viruses. They can only help remove them from the air.
A common way viruses and diseases can be transmitted is by touching an infected person and then inhaling their respiratory droplets.
