So sit back and take it easy.
UVC light will make it easier to breathe.
Understanding HEPA Filters and UVC Air Cleaning
What is a HEPA Filter?
Before we talk about cleaning the air with UVC, it is important to know what a HEPA filter is.
HEPA filters are a type of air filter that can get rid of at least 99.97% of dust, pollen, mold, bacteria, and other airborne particles bigger than 0.3 microns.
High-efficiency particulate air filter is what “HEPA” stands for.
Either plastic (PP+PET) or fiberglass is used to make HEPA filters.
They are made of a mat of randomly arranged fibers that can catch things like pollen, viruses, bacteria, mold, and PM2.5.
How Do HEPA Filters Work?
HEPA filters work in three ways: by diffusion, by catching particles, and by squeezing them together.
When gas molecules smaller than 0.1 microns bump into each other, they slow down and take longer to pass through the filter.
This is called diffusion.
Interception happens when airborne particles stick to a fiber.
Impact is when bigger air particles get stuck right in the fibers.
HEPA filters are much better for your health than regular filters because they can stop mold spores, bacteria, and even some viruses.
They help clean the air and make it better by getting rid of allergens and microbes.
Most air purifiers, vacuum cleaners, and HVAC systems have HEPA filters.
To make sure the filter works well, it’s important to follow the maintenance and replacement instructions from the manufacturer.
UVC Air Cleaning: How Does it Work?
UVC air cleaning is a method that kills bacteria and viruses in the air by shining ultraviolet light on them.
UVC light has been used to clean surfaces and water for many years.
UVC light is a type of electromagnetic radiation with a wavelength between 200 and 280 nanometers.
Bacteria and viruses can be killed by this wavelength because it damages their DNA or RNA, which makes them die.
Air is sucked into the unit and passed over a UVC lamp to clean the air.
Ultraviolet light from the UVC lamp kills bacteria and viruses in the air.
Then, the air goes through a HEPA filter to get rid of any remaining particles.
UVC air purifiers are good at killing bacteria and viruses in the air, but they are not good at getting rid of gaseous pollutants like VOCs, NOx, SO2, or carbon monoxide.
Benefits of UVC Air Cleaning
UVC can clean the air in many ways.
First, it kills bacteria and viruses in the air well.
This can be very helpful for people who have allergies or breathing problems.
Second, UVC air cleaners are easy to use and don’t need much upkeep.
Third, UVC air cleaners are good for the environment because they don’t make any harmful waste.

HEPA filters are very good at getting rid of pollutants, dust, pollen, and bacteria that are in the air.
But they are not good at getting rid of gaseous pollutants.
Air purifiers often use HEPA filters to improve the quality of the air inside.
Effectiveness and Safety of HEPA Filters and UVC Air Cleaning
UVC Air Cleaning: An Overview
UVC air cleaning is a way to clean the air by using radiation from the sun called ultraviolet-C (UVC).
This method is often used to clean the air in air ducts, and it is thought to be the safest way to use UVC radiation because direct exposure to UVC can hurt the skin or eyes.
UVC radiation can also be used in upper-room ultraviolet germicidal irradiation (UVGI) systems, which use the right amount of UV energy to kill airborne pathogens.
How UVC Air Cleaning Works
Microorganisms can be killed “on the fly” by putting UVC fixtures in air-handling-unit (AHU) plenums, air-distribution systems, or HVAC ductwork.
A HEPA filter and UVC air cleaning can be used together to make the air even better.
Viruses, pollen, dust, bacteria, and other particles are taken out of the air by HEPA filters.
When UVC cleaning and HEPA filtration are used together, the air can be cleaned and filtered to get rid of harmful particles.
Combining UVC Light with Electrostatic Technology
In some cases, UVC light can be combined with electrostatic technology in one filter in an air handling unit (AHU), or an in-room unit can circulate the air through a HEPA or other filter and then apply UVC light.
This mix can be useful for getting rid of harmful particles in the air.
Safety Considerations
It’s important to know that UVC radiation can break down some materials, like plastic, polymers, and dyed textiles, and that some UVC lamps produce ozone, which can irritate the airways.
Also, most UVC lamps sold for home use have a low dose, so it may take longer for a given surface area to be exposed to the light for a virus or bacteria to be killed.
So, it’s important to use UVC systems to clean the air in a safe way.
People can get hurt if they get UVC directly in their eyes or on their skin, but this is less likely to happen if the UVC is put in an air duct.
There have been reports of people getting burns on their skin and eyes from UVC lamps that were not set up right in rooms where people can be.
Mercury, which is poisonous, is found in some UVC lamps.
UV Air Purifiers and Ozone Emissions
UV air purifiers that use UV light to kill viruses and bacteria in the air can release ozone, which is bad for people.
Instead of UV air purifiers, the Environmental Protection Agency (EPA) suggests buying devices with HEPA and carbon filters to remove VOCs, gases, and odors from the air.
UV air purifiers are usually quiet and may be able to get rid of bacteria in the air if they are used with HEPA filters.
However, they can’t get rid of VOCs or other gases in the air.
Air cleaners and HVAC filters can help get rid of some of the pollutants in the air, but they shouldn’t be the only things people use to protect themselves from SARS-CoV-2. When used correctly and safely, UVC air cleaning can be a good way to clean the air and get rid of harmful particles. Before putting this technology into a space, it is important to think about the possible risks and limits of it.
Germicidal UVC: The Key to Effective Air Cleaning
When it comes to air purifiers, one of the most important features to look for is germicidal UVC technology.
This type of UVC light is capable of destroying harmful microorganisms like bacteria, viruses, and mold spores, making it an essential tool for improving indoor air quality.
Germicidal UVC works by disrupting the DNA of these microorganisms, rendering them unable to reproduce and spread.
This not only helps to reduce the risk of illness and infection, but it also helps to eliminate unpleasant odors and allergens from the air.
When shopping for an air purifier, be sure to look for one that includes germicidal UVC technology for the most effective air cleaning results.

Pollutants Removed by HEPA Filters with UVC Air Cleaning
HEPA filters that clean the air with UVC are a good way to get rid of airborne particles.
HEPA filters with UVC air cleaning are a good way to get rid of dust, pollen, mold, and bacteria that are at least 0.3 microns (m) in size and are floating in the air.
HEPA filters are rated by how well they catch particles that are 0.3 m in size.
This is because 0.3 m particles are the hardest to catch.
This means that the efficiency of capturing other size particles is higher than 99.97%.
But HEPA filters don’t clean the air of gases or volatile organic compounds (VOCs).
UVC air purifiers can help with this.
UVC air purifiers are good at getting rid of bacteria, but they can’t do a good job of getting rid of VOCs or other gases.
HEPA Filters versus UVC Air Purifiers
The Environmental Protection Agency (EPA) says that HEPA filters are better than UVC filters for cleaning the air.
UVC air purifiers can’t get rid of odors, chemical fumes, and allergens, but HEPA filters can.
It is important to remember that cleaning or filtering the air is not enough to keep people safe from COVID-19. When combined with other best practices recommended by the Centers for Disease Control and Prevention (CDC) and other public health agencies, like keeping your distance from others and wearing a mask, filtration can be part of a plan to make it less likely that COVID-19 will spread through the air inside.
Best Practices for Air Purification
When choosing an air purifier, it’s important to think about what your home or office needs.
For example, a HEPA filter may be the best choice if you want to get rid of allergens from the air.
If you are worried about bacteria or viruses, you might find that a UVC air purifier works better.
As important as it is to use an air purifier, it is also important to follow other best practices for cleaning the air.
This means changing the air filter often, keeping the windows and doors closed to keep outside pollutants from coming in, and making sure there is enough ventilation.
HEPA filters that clean the air with UVC are a good way to get rid of airborne particles, but they are not the only way to clean the air.
When used with other best practices, like staying away from people and wearing a mask, air purification can help make it less likely that COVID-19 and other airborne illnesses will spread.
Maintenance and Odor Elimination with Air Purifiers
Replacing the HEPA Filter
The size of the room, the quality of the air in the room, and how often the air purifier is used all affect how often the HEPA filter needs to be changed in an air purifier with UV-C air cleaning.
Most of the time, you should change the HEPA filter every 6 to 12 months.
But some air purifiers have indicators that show when the filter needs to be replaced.
These monitor the filter’s condition and let the user know when it needs to be changed.
Follow the instructions from the manufacturer on how to change the filter, since some filters may need to be changed more often than others.
The HEPA filter can also last longer if the air purifier is taken care of regularly.
This means regularly cleaning the pre-filter and the outside of the air purifier and replacing the UV-C bulb when it burns out.
UV Air Purifiers and Ozone Emission
UV air purifiers that clean the air with UVC light don’t need much upkeep.
But it’s important to remember that these devices can give off ozone, which is bad for people’s health.
The Environmental Protection Agency (EPA) suggests using air purifiers with HEPA and carbon filters to get rid of gases, odors, and volatile organic compounds (VOCs).
Manufacturers of UVC lamps are responsible for following all regulations, including Title 21 Code of Federal Regulations (CFR) Parts 1000 through 1004, and section.
Potential Risks Associated with UVC Air Purifiers
UVC lamps sold for use at home have a low dose, so it may take longer to expose a given surface area to them for bacteria or viruses to be killed.
UVC radiation is often used inside air ducts to clean the air.
This is the safest way to use UVC radiation, since direct exposure to the skin or eyes can cause damage.
Installing UVC inside an air duct makes it less likely that the skin or eyes will be exposed.
Some UVC lamps make ozone, which can make it hard to breathe.
UVC can also break down some materials, like plastic, polymers, and textiles that have been dyed.
Some UVC lamps contain mercury, which is toxic even in small amounts.
This means that you need to be very careful when cleaning a broken lamp and throwing it away.
It’s important to ask what kinds of materials can be cleaned with UVC and if the lamp has mercury in it.
Eliminating Odors from the Air
Yes, an air purifier that cleans the air with UV-C can get rid of smells, but it’s not a good idea to leave it on all the time.
The best filter for getting rid of smells from the air is one made of activated carbon or activated charcoal.
UV-C light, which is used as a filter in air purifiers, can also remove smells from the air.
However, it also makes ozone, which can make it hard to breathe, especially for people with asthma.
Even though the amount of ozone it makes is very low, it is still not a good idea to leave it on all the time.
Air Purifiers for Odor Elimination
The Germ Guardian AC5250PT air purifier has a 4-step system for cleaning the air that includes a pre-filter, a true HEPA filter, titanium dioxide, and UV-C light.
The UV-C light in this air purifier can kill living viruses, bacteria, and mold spores, but you don’t have to use it.
Another good air purifier that gets rid of smells is the Germ Guardian AC4825E.
It has a real HEPA filter and an activated carbon filter that trap small smell particles to get rid of any lingering smells.
Pros and Cons of Air Purifiers with UVC Air Cleaning
The Pros and Cons of UV-C Air Cleaning Technology
In recent years, air purifiers that use UV-C to clean the air have become more popular because they are so good at getting rid of bacteria and viruses.
But there are some bad things about using these devices that you should think about before you buy one.
The Benefits of UV-C Air Cleaning Technology
UV-C technology kills bacteria and viruses in the air by shining ultraviolet light on them.
This technology has been shown to stop the spread of diseases like the flu and COVID-19 that can be spread through the air.
UV-C air purifiers can also help cut down on allergens like pollen and pet dander in the air.
The Risks of UV-C Air Cleaning Technology
One big worry about UV air purifiers is that some of them give off ozone gas, which can make it hard to breathe, especially for people with asthma.
The Environmental Protection Agency (EPA) says that you shouldn’t buy air cleaners that put out ozone, like UV air cleaners.
During the process of cleaning the air, some UV air purifiers also make ozone.
Another worry is the possibility of being directly exposed to UVC radiation, which can cause severe burns and eye injuries.
UVC radiation is often used to clean the air in air ducts, but exposing your skin or eyes to it directly can hurt you.
Also, some UV air cleaners are not good at getting rid of gases or volatile organic compounds (VOCs) from the air.
Choosing a Safe and Effective Air Purifier
It’s important to know that not all UV air purifiers release ozone, and some are safe enough to use at home.
But it’s important to think about the risks UVC lamps pose to people and things, as well as the chance that viruses won’t be killed completely.
It’s also important to make sure the unit is set up correctly and used by people who know what they’re doing.
When choosing an air purifier, you should think about what you need and what the device can do.
Look for air purifiers that have been approved by reputable groups like the Association of Home Appliance Manufacturers (AHAM) or the California Air Resources Board (CARB).
These certifications make sure the air purifier meets certain standards for safety and performance.
