Best Air Purifiers 2023
Air purifiers have become an essential household since the outbreak of covid-19. A good air purifier should clean the air and filter pollen and other dust allergens. These devices come with a specialized filtering process that targets the microscopic particles in the air that might be harmful to you to inhale.
Without these, your lungs will have to filter all these particles when you inhale. If you have asthma or allergies, or any other respiratory illness, you can understand what these airborne irritants can do. This is why you need a good quality air purifier in your vicinity indoors.
As air purifiers are available in all shapes and sizes, choosing the best one can be a daunting task. This guide has highlighted some key points you consider when looking for the best air purifiers.
So, let’s dig right in!
Different types of pollutants
There are different types of pollutants present in the air. These contaminants include the likes of:
- Pollen
- Dust
- Dust mites
- Fungi
- Plant spores
- Mold spores
- Mildew
- Pet hair and dander
- Wood and tobacco smoke
- Different household odors (chemical cleaners, cooking, etc.)
- Toxins coming from pesticides, and aerosol sprays
- VOCs that are there in paint, cleaning supplies, varnishes, building materials, and carpets
Different types of air purifiers to tackle these pollutants
Air purifiers run different types of filtration procedures to clean the air we breathe. You might notice that other brands use different filtration processes, but primarily there are only four types. And various brands use a combination of different filtration technologies.
High-Efficiency Particulate Air (HEPA) filtration
This process is the gold standard when it comes to air purification. It involves a highly dense paper filter that can trap airborne irritations and contaminants. There are further different subcategories of HEPA filtration.
True HEPA can capture particles of up to 0.3 microns in size and clear 99.97% of different airborne microorganisms. You can also find HEPA-like or HEPA-type to capture 2 to 5-micron size particles. It means HEPA-type has 600% reduced efficiency as compared to True HEPA.
Ionic filtration
This filtration technology emits a cloud that charges ions into the air and latches on to those airborne irritants. With this process, the impurities in the air fall on the floor or nearby surfaces.
Some models feature electrostatic collection plates and get rid of the fallen particles. With this process, those ultra-fine particles of up to 0.01 microns can be cleared out of the air as well. But this process also creates a small amount of ozone and doesn’t remove odors.
Carbon filtration
These purifiers have activated carbon filters that have millions of tiny pores that are absorbent. With a large surface area, this filter works great to trap fumes, odors, and gases. But this process is not highly effective in capturing or trapping the irritants from the air.
UV light filtration
These purifiers have UV-C band ultraviolet light, which is safe for humans and has no side effects. But this filtration system cannot work as a standalone solution because it can only target germs, bacteria, and viruses.
Two different versions of these types of air purifiers
There are two different versions that you can use all these four types of air purifiers.
Classic version
These are the traditional air purifiers, and they don’t provide you with any feedback about the current air quality. You will have to rely on them that they are managing it all effectively. The only way to find out about their performance is to check how dirty the filter gets.
Smart version
These air purifiers come with a mobile app that will tell you all the details you want to know about the current air quality. They can also tell what kind of pollutants they are capturing. And you have a measurable performance at your disposal that your air purifier is working fine.
Points to consider when buying an air purifier
ACH and CADR
One of the most common features you will notice when looking for a good quality air purifier is that they come with these ACH and CADR ratings. ACH means air changes per hour, and it tells you about the overall efficiency of your air purifier.
It will tell you how frequently an air purifier changes the air in your room. Most of them come with a 4x, 5x, or 6x rating, which means the unit can change air this many times in your space.
On the other hand, CADR means clean air delivery rate, and the goal here is to tell you about the overall capacity of a purifier and how big a room it can handle. This rating was developed by the Association of Home Appliance Manufacturers and is available on units that the organization tests.
Choosing the right size
To put it simply, you need to go for an air purifier that comes with a square footage rating either equal or greater than the size of the room you will be using it in. you must measure the area of your room by measuring its length and width and multiplying them together. And look for a purifier that covers the same or bigger space than that.
Additional features
You can also go for some other features like pre-filter, digital controls, changeable fan speeds, indicators for filter replacement, programming timer, carrying handles or wheel casters, air quality sensors, and others for further convenience.
Conclusion:
To find the best air purifiers, you need to look at what size area you want to cover. Go for the unit that covers an equal amount of space, at least. Also, go for True HEPA technology because that is the best of all. You can also opt for purifiers that use multiple filtration processes to get the air pollutants and clean them for you to inhale.
