In this article, we’re going to answer two of the most common questions people have about air purifiers:

  • “What Does a Air Purifier Do?”
  • “and How Do Air Purifiers Work?”

We’ll explain everything you need to know about what is an air purifier machine and what types of contaminants they can get rid of inside your home.

What is an Air Purifier?

In simple terms, these devices remove pollutants and allergens from the air so you don’t breathe them into your lungs.

The benefits of having an air purifier are two-fold:

  • it helps you breathe better
  • and keeps you healthier by getting rid of harmful airborne toxins

The truth is that there are millions of microscopic particles floating in the air around you. With every inhale of your breath, you pull some of these particles into your lungs. If you have asthma or allergies, then you most likely notice the negative side effects of breathing in bad particles faster than someone who does not have these conditions.

Unfortunately, no amount of dusting or vacuuming can ultimately fix the problem of airborne pollutants.

In fact, these actions can actually make the problem worse by stirring up the harmful particles and pushing them back into the air.

By adding an air purifier to your home, you can ensure that particles that cause breathing and health problems are eliminated from the airspace around you.

What you’ll notice that after using one inside your house is that you’ll have an improved immune system, deeper sleep, and an overall better feeling of health.

If you suffer from asthma or allergies, you should also notice a significantly lesser amount of respiratory and nasal issues.

So, How Do Air Purifiers Work?

This question is a little bit more complicated to answer because some air purifiers use more than one type of technology to clean the air.

The four major types of air filtration you’ll find on air purifiers include:

  • HEPA filter
  • Carbon filter
  • Ionic generator
  • Ultra Violet radiation

If an air purifier is built with a HEPA filter, it operates by pulling air into this dense, paper filter and trapping the particles within it so they can’t float back into the air. HEPA room cleaners are great for people who have asthma or allergies because they can to capture up to 99.97% of particles that irritate these issues from the air.

A carbon filter works by collecting pollutants that create smells and odors inside your home. A HEPA filter cannot do this. If you want a fresh smelling home, getting an air purifier that includes a carbon filter is the best choice.

An ionic generator is another type of technology that air purifiers may or may not use. This feature works by sending out ions into the air that latch onto harmful particles. This causes the pollutants to become very heavy and can’t remain in the air. These particles then fall to the ground or become trapped in a collection plate that is on the device. A room ionizer air cleaner is the most affordable type of air cleaning device you can buy.

The final type of air filtration you’ll find on an air purifier is Ultra Violet lighting. This non-lethal radiation is emitted from the device and attacks bacteria and viruses that are floating in the air. It works by breaking apart the molecular structure of these contaminants, which then renders them harmless to your health.

This sums up the various methods on how do air purifiers work. As we mentioned above, some products include one or more of these features to strip the air from harmful particles. Depending on how you want the product to operate will determine which options you should look for in a device.
