Answering the question “How do air purifiers work?” is becoming more and more important in this day and age. According to various studies conducted by the EPA, the air indoors can be up to 100 times dirtier than the air outdoors.
Air can carry harmful pollutants, bacteria, viruses, pollen, dust, mold, smoke, and much more. Having a clean and safe indoor environment is more important than ever before.
Our guide will show you how the different types of air purifiers work. By the end of this article, you’ll know which type of filter matches your needs.
Let’s get into the guide!
How Do Air Purifiers Work – The Basics
The general function of an air purifier is to clean the air of all contaminants that could be harmful to you. Purifiers use various technologies and methods to intake air, clean it, and release it contaminant-free on the other side. There are 4 types of air filters and we’ll take a look at each one in more depth in the next couple of sections:
- Ionizing purifiers
- HEPA filters
- Activated carbon filters
- Ultraviolet light purifiers
Each of these specializes in targeting different types of contaminants in the air. Let’s take a deeper look.
How Does an Ionic Air Purifier Work?
These purifiers work by emitting negatively charged ions into the air. They latch like heavy magnets onto various contaminants in the air, making them too heavy to float – causing them to fall to the ground.
The contaminants won’t be completely gone and you’ll have to wipe down the surface they fall on to. This should answer the “How does an ion air purifier work?” question. Ionizing purifiers are best at removing the following pollutants from the air:
- Allergens (including the ones emitted by your pets)
- Mold spores
Ionizing purifiers are great solutions to the “How does an air purifier for mold work?” question.
How Does an Air Filter Work – HEPA Filters vs Activated Carbon Filters
HEPA filters use very dense materials to trap pollutants down to about 3 microns in size. This happens as the air passes through the filter. HEPA filters remove:
- Visible smoke and fumes
- Some larger bacteria
- Mold spores
Activated carbon filters use a very porous material that absorbs the pollutants as the air passes through. The porous material is specially treated and is excellent at removing:
- Gases and vapor from the air and smoke
- Cooking odors (especially if you burn your food)
- Various chemicals
- Paint smells and thinners
In summary, if you want to remove smells and odors, activated carbon filters are the better choice for you.
How Does an Air Purifier Work – UV Light Purifiers
During global pandemics like the ongoing coronavirus, these filters can be life-savers. UV light purifiers use short wave UV light radiation to kill airborne pathogens and bacteria that pass through it.
It kills about 99.97% of all airborne viruses, pathogens, and bacteria. If you want your indoor space to be free from these types of airborne contaminants, then you’re going to need a UV filter.
It’s a fresh take on how an air purifier works and is the only type of purifier that can keep you safe from pathogens, viral, and bacterial infections.
How Does an Ozone Air Purifier Work?
I’ll keep this as basic and non-scientific as possible. Ozone purifiers take oxygen from the air and give it a powerful charge. These highly-charged oxygen particles are released back into the air.
When they come across mold, dust, and other contaminants in the air, the third oxygen particle binds itself to the molecules of the contaminant, eliminating it from the air.
How Well Do Air Purifiers Work?
This is an important point to clarify, as some purifiers are specialized and won’t do it all. For example, a HEPA filter air purifier isn’t going to remove viruses and pathogens from the air it filters. You need to know what your needs are before deciding which filter to get.
Once you have the right filter for your needs, you’ll be able to tell how well it works. Effective air purifiers can remove up to 99.97% of air contaminants from the air that it processes.
This will only be true if the purifier you have is good quality and is well taken care of. Just like everything else you buy – you get what you pay for.
If you want effective performance and protection, don’t skimp on the original purchase.
Are Room Air Filters Effective?
The smaller the room that the filter is placed in, the more effective it will be. This is because there is a higher chance of most of the air being processed at some point by the filter.
Rooms that have better air circulation are also likely to be better handled by an air filter. If the room is a high traffic area in your house or office, the filter will have a tougher time ensuring that all the air is clean.
Should You Get an Air Purifier?
Yes, you should. If you can afford the initial cost of the air filter, it’s well worth the money. The long term health cost can be far greater than the initial financial cost!
We live in a world where climate change and rising pollution levels (as well as viruses and pathogens) threaten us. Taking simple steps and getting an air filter or air purifier will go a long way to ensure you stay healthy and strong, despite the environmental chaos that seems to be enveloping the world.
