Many people wonder if air purifiers are really effective at removing germs, dust, mold, or smoke, and the answer is yes. Even the experts assure that these devices guarantee a contaminant-free environment, which helps to reduce the annoying symptoms of asthma or other respiratory conditions.
Without going any further, the air purifier is exclusively designed to clean the air in your home, eliminating all the harmful particles, such as odors, viruses, bacteria, and pet dander.
However, as is often the case in the market, not all air purifiers will be equal in efficiency and quality, so you should pay attention to specific points before deciding which one to buy.
In this post, I will explain how do air purifiers work? Are they really effective? Some factors that you should consider when making a decision.
What is an Air Purifier?
An air purifier is a device used to eliminate polluting elements in the home and clean and purify the air, especially from smoke and particles that float in the environment.
What do you get? Create a healthy atmosphere by eliminating odors and chemical agents and improving the quality of the air you breathe.
Advantages of Having an Air Purifier for Allergies
The quality of life for those who suffer from allergies and other respiratory problems caused by poor air quality is improved with an air purifier.
They reduce dust particles by 99% since they suck in any smoke that is produced in the air, and they eliminate pet hair and other particles that are the cause of said allergies.
How do air purifiers work?
As a general rule, the operating process is as follows:
- The air purifier fan sucks in dirty air.
- With the pre-filter larger particles such as dust, dirt and hair are filtered.
- Next, formaldehyde, benzene, and other toxic gases and odors are filtered out of the air by means of the activated carbon filter.
- Finally, small particles such as pollen, bacteria, or viruses are filtered through a HEPA filter.
- And with the UV light that can be activated inside the device. It eliminates germs and odors (caused by animals, cooking, or tobacco smoke).
Once the process is finished, clean air is emitted into the room.
Regarding its management, the air purifier has all the available options that make its operation totally autonomous:
- Previous diagnosis
- Automatic operation: the fan speed automatically adapts to the quality of the air.
- Timer for automatic shutdown.
- Night mode, for use during saving hours. Silent operation and without light.
The equipment itself notifies you of the maintenance and the necessary changes to filters.
Although anyone will appreciate having an air purifier at home, it is ideal for combating allergies and respiratory problems such as asthma and getting rid of pollen and mites.
What types of filters do air purifiers use?
Air purification is the removal or capture of particles present in the air that can be harmful to people’s health. This purification can be carried out using different techniques. But in any case, it should guarantee the neutralization of harmful substances such as allergens, bacteria, viruses, spores, mold, yeast, fungi, and VOCs, thus reducing the level of air pollution.
Currently, systems that use HEPA filters supplemented with activated carbon filters make up 63% of the market offer to combat poor indoor air quality and are replacing the use of ozone, ionization, or electrostatic precipitation.
HEPA Filters + Active Carbon Filter:
HEPA (High-Efficiency Particulate Air) filters are made up of a mesh of randomly arranged fibers, generally fiberglass, with diameters between 0.5 and 2.0 μm. As the airflow passes through the filter, the particles are trapped in this network.
HEPA filters are highly effective at capturing airborne particles larger than 0.3 microns. It includes most airborne pathogens such as bacteria, certain viruses, pollen, mold, animal dander, or mites.
An electrostatic precipitator uses electrostatic energy to attract and hold dust and other particles. These air purifiers typically first draw the air through an initial filter and then subject it to an electrical charging process. Although they often do not produce as much ozone as an ozone generator, ozone is a side effect of the air charging process.
Air purifiers based on UV-C light disinfection contain a lamp that projects this light inside an aluminum chamber. This system by itself is not capable of retaining particles, so the air purifiers that incorporate it are usually complemented with other alternative means such as filters of greater or lesser capacity or ionizers.
Air purifiers that contain an ionizer electrically charge the molecules of the different gases that make up the air, creating an electric field of ions (negative charge). These negative ions bind to airborne particles such as dust, bacteria, or pollen (usually positively charged), causing them to settle and stick to surfaces.
So what should I look for in an air purifier?
- CADR Rating (Clean Air Delivery Rate): This indicator measures how fast the purifier cleans out smoke, dust, and pollen. I recommend looking for a CADR of at least 300, but if you choose 350 it will be more than enough.
- Size of the room you want to clean: For optimal performance, you should look for an air purifier that is suitable for the size of the room you want to clean. The ideal would be to choose a model that covers more square meters than your space in order to ensure its effectiveness.
- HEPA Filters: As I already mentioned, true HEPA filters are the only ones that are truly effective at combating ultrafine particles, the industry standard for which is that the unit must be able to remove at least 99.97% of particles that are 0.3 microns in diameter.
Finally, should you buy an air purifier?
If you are allergic or asthmatic, an air purifier with a HEPA filter will be extremely useful and significantly improve your quality of life. Since -as I mentioned before- it will eliminate all the fine particles that enhance those annoying respiratory symptoms.
And, if you don’t suffer from any kind of condition, the air purifier would be good for you too, because who doesn’t benefit from breathing pure and clean air?
