So, you’re now wondering… how to choose an air purifier that’s best for you.

As you may already know, air purifiers come in all shapes and sizes, as well as use different types of technology to filter the air.

At first, it may seem overwhelming to choose the right device, but after reading the information below, you’ll be well equipped to make the best decision for getting an air purifier for your home.

First, Ask Yourself “What Do You Want the Air Purifier to Do?”

When trying to find the right air purifier, the answer to the question above is very important.


Because, knowing exactly what you want the product to do will guide you in the right direction for which device to get. Knowing this simple answer will really make your decision much easier.

When it comes to the technology of air purifiers, each type of device is designed to combat specific kinds of particles better than others.

For example, one product may be excellent at removing odors and smells from a room, but not the best at getting rid of pet dander. Another device may be great at removing allergens from the air, but has no effect on harmful bacteria.

Next, we’ll go over all of the different kinds of air purifiers and help you discover which one will fit your specific needs.

Next, Pick the Right Type of Device

True HEPA Filter Air Purifier

This type of air purifier is a good choice because it removes 99.7% of particles as small as 0.3 microns.

To help you visualize how small that is, a human hair is 2 microns in size, which is 4-5x larger than most airborne contaminants.

This type of product is excellent at capturing particles that irritate allergies and asthma. If you want to eliminate toxins like pollen, pet dander, mold spores, etc., this is the best type of air purifier to get. Since, this kind of device uses a physical filter, it traps all particles into it and doesn’t let them get released back into the air.

Ionic Air Purifier

The technology behind this type of device does not use a paper filter to capture particles. How it operates instead is by emitting charged particles into the air that latch onto airborne contaminants.

After creating a bond, these particles fall onto the floor or if equipped, are collected on an electrostatic collection plate.

The real power behind an Ionic air purifier is the fact that it can remove particles as small as .01 microns in size from the air. This is 3x smaller than a HEPA device.

The only problem with this product is that the charged particles it emits can be problematic for asthmatics. The other downside is that not all products include a particle collection plate, meaning that harmful contaminants can reenter the air.

Optional Features to Look for: Ultra Violet Light and Carbon Filter

When deciding on which is the best air purifier for your needs, two optional features you’ll come across are Ultra Violet Light technology and the inclusion of a Carbon filter.

If you want to create the most sterile breathing environment possible, getting a product that includes an Ultra Violet light will be a good choice. This powerful feature operates by sending out electromagnetic radiation that breaks apart the DNA of bacteria, germs and viruses. Once this occurs, these types of particles become harmless to you.

On the other hand, while all of these technologies mentioned so far are great at creating better, breathable air, neither of them are very good at removing odors and smells. That’s where a Carbon filter upgrade fits in. This special filter is excellent at eliminating odors caused smoke, pets, cooking, mold and more.

Making Sure it’s Powerful Enough to Handle Your Needs

Another key feature to look for when selecting an air purifier is to make sure that it’s powerful enough to work in the space you intend to place it.

What you don’t want to find is that you got a product that isn’t able to effectively purify the room(s).

In the specification list on all air purifiers is a rating that includes the words “Average Coverage” or “Room Size.” This number will be written in square feet, such as 100 sq. ft.

When selecting a device, it’s important that you first measure the room(s) you are going to use it for inside your home. Then compare this number to the rating on the device. Just make sure the product you buy can handle the size you need.
