How do air purifiers work?
First of all, I will say to you Yes, of course, air purifiers really work.
How does it work? Well…
That’s what we will discuss in our article.
Stay with me until the end to know all the information.
Air purifiers consist of a fan filter and more. Fan is used to circulate the air. Also, filters are present that catch any contaminants and filtrate the air. Then fresh air comes out into your home environment. Usually, air purifiers contain two filters and a single fan.
An important feature is the pre-filter machine. This increases the lifetime of the main filter or the second filter.
Pre-filter traps large pollutants in the air. This helps make the original filter work easier. Besides, the second filter catches any remaining particles that the pre-filter might miss.
Can you believe that an average of $250 million is spent yearly on-air purifier by the Americans for their home?
Why do they use it?
An air purifier is a device. It is used to purify the air and protect us from all the pollutants. Our home and the outdoor environment contain many, many different types of pollutants.
So, air purifiers can help to remove those pollutants.
They can remove all types of airborne contaminants: Such as dust, germs, allergens, bacteria, pet dander, etc.
The way CORONAVIRUS has spread this year, it wouldn’t be a bad idea to keep your home environment clean with an air purifier.
Well… one may ask “How many different types of air purifier filters are present?”
Well, guess what? That is what we will be talking about right now!
Best two types of air purifier filters
Filters are an integral and essential part of any air purifier. Without the filters, it is useless. Now, we will discuss different types of filters that various air purifiers use, down below…
High-efficiency particulate air (HEPA) filter
At present, HEPA is the best air purifier filter in the market. They have served well and are the most known filters used in air purifiers.
HEPA filters work with the help of a net-like structure called fibers. The fibers of HEPA filters trap dust and dirt particles in three ways.
Firstly, the filter fibers catch the particles through absorption and it is called impact. When they flow along in the moving airstream some are caught, they move too close to fiber and get trapped by interception.
At lower airspeeds, by diffusion, some are trapped.
There usually remains a lot of dust, dirt and other contaminants of the air in your home. HVAC filters play an essential role in keeping your home’s air clean.
Okay, these filters work great, but how do HVAC filters work?
Air is pulled in through the blower and circulated through the ducts. That is how the HVAC filter cleans the air. It is that simple.
The material, usually pleated cloth or paper, traps any contaminants that are in the air, whereas the air is forced through the filter.
Next, we are going to discuss some top air purifiers that are available in the market.
And of course, you will know air purifiers how do they work?
Then, let’s get started!!!
HEPA Air Purifier
HEPA means High-Efficiency Particulate Air.
The HEPA type filters are known filter which is used in air purifiers. They work well for filtering particles. It does a great job of filtering. That is why it is the best filter in the market.
The HEPA traps and catches the different particulates which are present in the air by using a dense arrangement of fibers.
The good news is that it captures 99.9 percent of the contaminants. And also, HEPA captures particles that are as small as 0.3 microns. Therefore, they cover bacteria, viruses, chemicals, and certain molds that the human eye is unable to see.
When a HEPA start a filtration process, it uses three different methods for filtration. Those methods are impact, interception, and diffusion which have already been discussed before.
That is how the HEPA filtrates so excellently. It’s a proved fact….
An important note is that the HEPA can’t remove odors or other chemicals. But, many people make a mistake and buy HEPA air purifiers for removing odors.
I think you will remember it, won’t you?
And because of this performance, HEPA air purifiers are the most popular Right now.
HEPA cleans out 99.9 percent of the airborne particles. But, there will still remain some bacteria and viruses even if you get a true HEPA.
Ionizer air purifier
The ionic air purifier or ionizer is a model of high-tech air purification. This purifier works using an ion generator.
The ozone air purifier sends out a continuous flow of ions through the generator that are negatively charged. The ions are attracted to dust, allergen particles and other pollutants.
After that, firstly they interact with one another then the pollutants become too heavy. Next, it automatically drops down to the floor. Because of that, it will be easy to remove or sweep out from the floor.
Keep in mind, the ionizer has some problems. For instance, it neutralizes the contaminants for a while but does not remove the particulates completely. That is why some of the inactive particulates reenter the air; it is the cause of the issue.
This issue could be solved by the vacuum cleaner. Also, an electrostatic collection plate might be present in some air purifiers with ionizers to take out the downed particles.
Some type of air purifiers with ionizers might produce harmful ozone. Are you aware of it? This is one big problem with ionizer filters.
Because ozone is one type of gas that is harmful to the human body. Especially, it is very annoying for those people who are already suffering from asthma, allergens and other breathing-related problems.
The filter is an essential part of any air purifier. Before you learn do air purifiers really work, you should know the filters.
Activated carbon air purifier
Many people think that HEPA works for odor problems and reduces other harmful chemicals from the air. But, it is a mistake you do not wanna make.
Because the HEPA filter does not work for this kind of issue. Just ineffective!
Activated carbon filters have chemical boarding and high absorbent ability. It contains many molecular-sized pores. These oddities make them a very effective tool for capturing pollutants, for example, odors, gases, emissions, and tobacco smoke. Once these pollutants are captured, there’s no chance they will go back into the air because of the eliminating recontamination.
Air purifiers with activated carbon filters are particularly helpful for those people who have multiple chemical sensitivity (MCS). Because they are absorbing formaldehyde which remains included in our home substances like carpet, wood painting, and furniture upholstery.
It also removes chemicals in household cleaning items. And makes the environment much more breathable for those people who are suffering from asthma.
Moreover, it is very helpful for babies, elder people and children.
It is noticeable that the carbon filter is not as effective as the HEPA when it comes to taking down the small particles that roam around in the air.
UV air purifier
UV technology does not get rid of airborne particles. That is why most of the time it is used in conjunction with particulate filter systems. However, it is an excellent method to kill germs, for example, bacteria and viruses.
This technology of air purifiers have a UV lamp installed. As microorganisms pass by the radiated UV rays from the lamp then cellular or genetic damage occurs, destroying the microorganisms.
This type of air purifier’s effectiveness lies in two aspects. The first one is the wattage of the light and the other is the time of exposure to the light. The UV lamp must be monitored and replaced depending on the condition of the lamp. Of course, you should follow the manufacturer’s recommendations.
Therefore, most air purifiers that employ UV for the highest performance of the filtration start filtration by the HEPA and activated carbon and use the UV as a final stage of filtration.
These were the four of the best purifiers. So, now you can judge yourself, do air purifiers really work?
Now, you should know what type of benefits you will get using the air purifiers. Continue reading…
Benefits of air purifiers:
work along with the benefits.
Important thing is that most of the disease to our body is made from the air. Such as allergies, asthma etc. because many particulates enter our body. An air purifier works effectively on this kind of issue.
Also, it helps neutralize smoke. Your loved one is making the house smelly and smoky? Well, you cannot get rid of those loved ones. Then what should you do?
I think the right air purifier can give you the proper solution to get rid of this problem. They can help remove smell and smoke altogether before they settle into your home.
If you burn something when you are cooking then it will create a burning odor. What is the solution to this issue? Here is the explanation to get rid of this. The air purifier does not only clean the air, but it also removes unpleasant and burnt food odors.
If you have any pet animal friends then it can put allergens into the home air. I haven’t dared to suggest getting rid of them and you don’t need to either.
Air purifiers remove airborne allergens from the air. This is the right solution to clean the air.
Are your children suffering from flu and cold? True HEPA air purifiers capture the harmful particles and can neutralize up to 99.97% of the airborne microbe with UV bulbs.
Besides, our homes are full of specks of dust. You cannot do anything to prevent Dust from accruing. An air purifier helps trap dust, leaving you with less to clean.
Air purifiers fit in all the places. Because they come in various sizes and features.
What is the actual benefit of air purifiers?
Having an air purifier has many benefits. But, the one that stands tall is the benefit of having clean indoor air.
Air purifier catches invisible and visible particles that can aggravate your health. They work swiftly and softly to remove pollen, odors, pet hair and even smoke.
How long does it take for an air purifier to clean the air in a room?
This is a surprisingly difficult question to answer…
It all depends on the size and power of the fan which the purifier uses.
How long does it take for air to flow through the purifier? Who knows! But, this time can be shortened using CADR rating, that is measured in cubic feet per minute (CFM).
Despite this, the CADR rating is not a proper gauge of how well an air purifier performs.
A purifier with a low-efficiency filter and a massive fan might have a very high CFM output, but the air might not be cleaned very effectively. A quality filter with a smaller unit can take longer to cycle the room. But, it does a more accurate job of removing pollutants from the air.
In conclusion, the larger the space to clean, the more time it will take.
Are they safe?
Some air purifiers produce ozone which is harmful to the human body. But, they kill microorganisms. The United States Environmental Protection Agency besides some of its State chapters, for example, the California Environmental Protection Agency warns against these devices.
Except for those, and the fact that cheap HEPA filter is not substituted frequently which results in a risk of fungus growth. Air purifiers are generally safe.
Are they effective?
Umm hello? Of course, they are!
Well first of all, it is true that some types of air purifiers do not work effectively. It depends on air purifier’s quality. But, a good quality air purifier will definitely improve air quality. Moreover, it helps with certain health problems. They are able to reduce asthma and allergies.
Indeed, most of the time, it depends on your decision. First of all, you need to clarify your specific air quality issues. Later, if you purchase the right kind of purifier which you need then I hope that it will work effectively. So, know what you need to buy…
How different types of air purifiers work for different types of pollutants
Air purifiers use different filtration technologies to clean the air. Take a look at how the main types of air purifiers work for various pollutants:
HEPA: True HEPA filters use fiber that captures 99.9 percent of the contaminants and particles which are bigger than 0.3.
This purifier works well for viruses, bacteria and certain molds that the human eye is unable to see.
HEPA filters are unable to remove gaseous toxins, including VOCs from the air.
Ionic/Ionizer: An ionic air purifier imparts an electrical charge to particles that pass through it. It does not remove gaseous compounds at all.
They remove dust, allergen particles, and other pollutants. Also, ionizers release ozone that can make create unsafe levels in an indoor space.
Are air purifiers worth the money?
Air purifiers work outstandingly to reduce the level of contaminant particles in your home. In recent years, many advance features have come in the technology of air purifiers.
For the home environment, they are very effective. They remove toxins, dust, pet hair, and other substances.
Truth is that air purifiers really do work and allow you to breathe some fresh air in.
Your and your family’s health is essential and should be protected however possible.
If you want to purchase a purifier then many cost-effective solutions are available on the market. The key feature to watch out for is that the model you choose should come with a HEPA filter.
This type of filter will not disappoint you because it provides you with the highest level of protection against the harmful air contaminants.
What they won’t work for
An air purifier will not be able to remove or neutralize all those particles which are already sitting on the surface. Particles not only sit on soft surfaces but also hard surfaces.
Hard surfaces like your walls as well as soft surfaces such as furniture, bedding, and carpeting.
Before investing money in an air purifier, firstly you should consider a home air quality test. Then you can take a decision of the one you need.
How to choose the right air purifier
We have already discussed whether do air purifiers really work or not.
There are many different types of air purifiers available in the market. But, which one is right for your needs and will give the best results?
How will you know?
Now, powertoolsguyd share with you, how will you choose the right air purifier.
To decide on an air purifier, there are three conditions that you need to keep in mind. Firstly, you should keep the room size under consideration. Secondly, keep track of the specific pollutants which you want to control. Lastly, know the overall sensitivity of people in your home.
Generally, if your room is large then you will need larger purifiers. They can be small, medium and large. So, you should choose the right one which will provide the best filtration.
The best way to know the airflow is to check the CADR rating of the air purifier. It’s coming up later on!!!
If you want to clean the larger room then you should pick the higher CADR number.
So, in a small room, like a college dorm room, a small air purifier will help you. This type of filter does not need too much space.
Also, if you have a larger area, such as an office, living room or an open kitchen, a larger purifier can be the proper choice like the Erik 650A.
As you need to control dust, dander, pollen or other airborne pollutants, you should be strategic at the time of buying the air purifier.
You should avoid the type of air purifier that produces ozone which is harmful to the human body.
Why do you need to check the CADR rating?
It is the best way to know the airflow. Because the CADR is a measure of the filtered air volume which comes out of the air cleaner.
Do air purifiers work for smoke?
Yes, all air purifiers remove tobacco smoke.
Air purifiers actually remove the particles floating in the air due to smoking. Except for some air purifiers which are designed just to remove the odor or toxic gases associated with smoke. They are not able to do this.
Do air purifiers work for dust?
YES! Actually most of the air purifiers are designed to remove dust from the air. So, if you use an air purifier in a room then it will trap these particles before they have the chance to settle down. They also reduce the accumulation of dust on our books, carpets, and shelves.
In conclusion, if you want to keep your indoor or outdoor air clean with no muss, no fuss for you and your family then air purifier or this article will be your best solution.
I hope that you have no doubt about air purifiers and how do they work.
