How do air purifiers work?

In this part, we’ll break down different technologies and methods to purify the air. Every major or common or popular type of air purifier uses at least one of the following technology or method.

Using Mechanical Filtration

It is the most common type and easy to understand. This filtration method is used by the air purifiers with labels called HEPA. HEPA is basically a standard to make air purifiers. You can read “what is HEPA air purifier” to know in details.

These filters use a fan to collect the air and channel it through a filter or series of filters to make it clean. Unlike the air conditioning machine, it collects the air from inside your room, cleans it, and flows back to your room again.

The filters are designed in such a manner that it can cover the maximum area with a success rate of 99.97% of removing particles larger than 0.3 microns.

But be careful out there before buying because many manufacturers sell their products without maintaining the standard. If you don’t want to get cheated, you should read our article on the best whole house air purifier.

Using Electrostatic Precipitation

This one is an interesting one. The electrostatic precipitation technology also uses a fan to draw the air into the machine. After that, it passes the air through an electrical field.

That field can be created using a high-voltage electrode or wire and it charges the particles in the incoming air. The charged particles then pass through another section where oppositely charged collector plates are placed.

There is a serious concern about this method despite its high efficiency in cleaning the air. Research shows that this type of air purifier creates ozone while purifying. The ozone is good up in the sky but it’s harmful at ground level.

You may find many manufacturers claim that their purifier creates the very little amount of ozone which is not so harmful. But don’t fall for that. Considering health hazards, you should avoid any kind of air purifiers that create ozone.

How Do Air Purifiers Work? The Basics

Did you know that a new standard is now in play to determine the quality of an air purifier? It’s called Clean Air Delivery Rate or CADR. The standard is developed by the Association of Home Appliance Manufacturers.

Using Ozone Generation

As I mentioned earlier that ozone at ground level is harmful to our health, you should avoid any type of air purifiers that says it purifies by creating ozone. You can imagine how harmful it can be.

Moreover, this technology doesn’t work like others in removing particles or contaminations from the air. So, what’s the point of having an ozone generator?

Using UV light

Killing bacteria, viruses, germs, mold, fungi, and spores, using UV light is the best way. Many industrial facilities use this kind of air purification method. The list includes hospitals, pharmaceutical plants, kitchens, operating rooms, breweries, dairies, meat storage, processing plants, bakeries, animal labs, and many more. So, you can seriously consider this technology for your residential air cleaning job.

Using Incineration

A very new but possibly the best way to treat your indoor air is using incineration. The process completes air cleaning by producing 400°C heat and passing the air through that heated chamber. The heat doesn’t get released and the whole process doesn’t make any noise like others.

A study even shows that this method can kill all types of harmful microorganisms with a success rate of 99.99% and reduces ozone level inside the house. Another big advantage of this technology will blow your mind away. It needs almost zero maintenance because there are no filters to replace or clean regularly

How Do Air Purifiers Work to Remove Gas or Odor?

Well, removing gas or odor is no magic. It’s simply done by adding another filter to your existing one. The filter contains charcoal which is also referred to as active carbon.

The oxidized charcoal is an amazing catcher of gases. Its countless bonding sites are responsible to do the trick. The large surface area can collect and eliminate gases very efficiently.

But continuous use can slowly decrease its efficiency. So, you need to check the filters regularly and replace when necessary.

Final words

Knowing everything about air purifier, selecting a cost-effective unit reading the best air purifier under $100, and placing it in your room, you can still get dis satisfactory results.

It’s because successful air purification depends on various things like the size of the room or space, the speed of the air cleaner, the number of air purifiers regarding the space to cover, the source and the nature of the contaminant, and the level of saturation of the purifier.

So, don’t get mad instantly and consult with an expert mentioning all those factors. The solution you’ll get will be the best for your situation.
