Best Air Purifiers of 2022

An air purifier takes different kinds of particles out of the environment. But not all units are equal. Depending on where you’re going to be using yours, make sure you’re choosing the top brand that will help with the airborne particles you’re concerned about.


Here’s what air purifiers do. They don’t emit anything into the air, rather they snatch airborne particles out of the air, sanitize them, and then the particles are released. Thus, people who think that this technology is simply glorified filters are wrong. They’re not filters, at all. They don’t separate good particles from bad particles. They, essentially, clean bad particles. The result is cleaner, healthier air quality. All that being said, they can come along with an air filter, but then they work together to make your air quality even better. So, depending on where you’re going to be using yours, make sure you’re choosing the one that will help with the airborne particles you’re concerned about.

Here’s a list of some of the pollutants that an air purifier can clean.


Use a HEPA air purifier for this problem. Filtering is more effective than just sanitizing.


These are pet dander, dust mites, and pollen for examples. These are best dealt with by a HEPA air purifier, as well.

Indoor toxins

You can end up with indoor toxins from household cleaners, personal products, pest control products, and more. An air purifier can help with eliminating some of these.


An air purifier can help with this. You have to know which type works best to eliminate the dangerous particles and gases from the environment. A HEPA filter can trap 99.97% particles of tiny particles. They can even trap 0.3 microns in size. This measurement is smaller than that of a tobacco smoke particle (1.0 micron).


Keep in mind that some airborne particles will land on something they will adhere to. The air purifier only works to sanitize the particles that are floating around in the air. They won’t rid your furniture or rugs of the toxins that land there.

How Do Air Purifiers Work?

Yes, they do really work. But, as was mentioned above, they work better on some particles than others and they won’t sanitize your entire house, just give you better air quality.

People who suffer from allergies will likely see a difference in their symptoms after starting to use this technology in the home. The same can be true for those with asthma. It’s important to keep taking prescribed medications from your doctor, though, even after getting a purifier.

Finding the right unit will help ensure they work better in your home. You need one that is the right size for the space you’re using it in. You also need to decide whether you should get one with a filter. The filter will often make the unit more effective to give you even better air quality and the chance to experience clean breathing.

You can help your air purifier to be more effective by regularly cleaning the surfaces in your home where bad airborne particles can land. You can also make sure to bathe your animals regularly, adjust the humidity in your home appropriately, replace old floor coverings, and change up your cleaning products to reduce harmful toxins from making it into the air in your home.

Now let’s take a look at some of the top units you can find on Amazon and what there is to love and not like so much about them.
