In this guide, you’ll get the answer to the question,” Do plasma air purifiers work?’

But we’ll also go over more than just the answer.

We’ll also explain, what is a plasma air purifier, how they work, are plasma wave safe, and the pros and cons of having one in your home.

Let’s jump in..

Do Plasma Air Purifiers Work?

Plasma air purifiers do work. In fact, not only do these purifiers work, but they work great! One of the reasons they work so well is because their filters are very small and, they can catch contaminants and particles that are extremely tiny. Hardly anything gets past one of these filters.

Another aspect of the purifier that people love is that it works efficiently without using a lot of electricity.

In fact, plasma air purifiers take up roughly the same amount of energy that a light bulb does, which means the difference in your utility bill won’t be a lot.

What Is A Plasma Air Purifier?

A cold plasma air purifier is a purifier that causes an atmospheric disruption in the air, which then causes the air to be its own filter.

This is accomplished by emitting equal amounts of positive and negative ions, which then form new clusters of ions that remove any type of airborne pollution or contaminants.

When shopping for air filters, you’ll notice that many of them work because they are a form of ionic purifier.

The plasma air purifiers do create low levels of ozone, but unlike ozone-based air purifiers, the levels are so low that the EPA has determined that they are still safe to use.

This is because most of these purifiers have ozone levels of 0.05 ppm, which is low enough that it is not a danger to people or pets.

How Does Plasma Air Purifier Work

Plasma air purifiers work rather simply.

First of all, they have very small filters that capture even the tiniest contaminants, something that other air purifiers simply aren’t able to do.

When the negative and positive ions are released, which have a makeup that is similar to water, they separate and then rejoin around the contaminants.

Once this happens, the contaminants become trapped in the filter and don’t have a chance to go back into the air.

Plasma air purifiers use specialized technology that is both low-cost and low-maintenance. Even the filters, which are extremely energy-efficient, only have to be replaced occasionally.

With plasma air purifiers, there is never any worry about constantly replacing expensive filters because they only have to be replaced once in a while.

Are Plasma Waves Safe?

Filters that use plasma wave technology are incredibly safe, mostly because of the dual ions created and used to get rid of contaminants in the air.

This is an effective but safe way to get rid of all types of pollutants. This type of filter and air purifier has been certified by the air resources boards in California as safe for humans and pets.

This says a lot because the state of California sets very strict safety standards when it comes to products that get rid of pollutants in the air.

>In fact, California’s standards are commonly much stricter than the other 49 states, so you can rest assured that technology using plasma waves is very safe for everyone.

The prices of plasma air purifiers vary depending on the brand, the size, and where you buy them from, but as a general rule, they can cost anywhere from around $75 to several hundred dollars.


ne thing you’ll want to look for is the square footage that the air purifier covers.

If you’re searching for a plasma air purifier for a room that is 500 square feet, you certainly don’t want to buy one that only covers a 200-square-foot room.

The opposite is also true. Choosing a plasma air purifier that is too big will be a waste of money.

It’s go

od to measure the room you want the air purifier to go in before going shopping for this item.

Also, keep in mind that there are plasma air purifiers for both individual and commercial use, and naturally, the prices will vary depending on what type you choose in the end.

Plasma Air Purifier Versus HEPA Filter

First of all, it’s good to remember that some air purifiers can be plasma air purifiers and still use a HEPA filter.


ency particulate air (HEPA) filters are made out of very dense materials and can remove 99.97% of all contaminants in the air.

This means that HEPA filters can take in 10,000 particulates and only three of them will escape.

HEPA filters also use air flowing through the machine to use.

In fact, th

is air is a must for the filters to work. True HEPA filters are considered some of the best filters on the market, but that doesn’t mean you need one to make a plasma air purifier work efficiently.

That being said, if you want the absolute best technology for cleaning your air, a plasma air purifier with a True HEPA filter is your best bet.

The Benefits of Plasma Air Purifiers

As with any product on the market, plasma air purifiers have both pros and cons. Here are three main benefits of this type of air purifier:

  • It is a very powerful air-cleaning system. Plasma air purifiers take advantage of numerous combined fan systems and filtration systems to make the purification process very powerful.
  • It is a very efficient air-purification system that can get rid of most particulates, including formaldehyde and even toilet odor.
  • It works quickly. You don’t have to have your plasma air purifier plugged in very long to notice a difference in the smell and breathing benefits it offers.

-block-heading">The Cons of Plasma Air Purifiers

While people tend to love their plasma air purifiers, the devices do have some disadvantages, and they include the following:

  • For the purifiers that use a high-voltage electrostatic system, the pollutants have to be adsorbed on the collector. While you won’t have to change filters with this type of purifier, the adsorption capacity is not that strong.
  • For the purifiers that use a filter net, you can use multiple filter nets to adsorb the contaminants. Unfortunately, it is time-consuming to replace the filter screen.
  • For the puri
    fiers that use both of these technologies, it’s possible that they may not be able to adsorb the very fine particles in the air.

Final Thoughts- Are plasma air purifiers good?

One of the reasons plasma air purifiers work so well is because they use both positive and negative ions, which do a great job of trapping the contaminants and removing them from the air. Plasma air purifiers also have very small filters and therefore catch contaminants that many other filters miss.

There are several types of plasma air purifiers, although they all tend to work the same basic way.

These are incredibl

y efficient devices that use both positive and negative ions to get rid of harmful particulates in the air. They are reasonably priced and get rid of all sorts of contaminants, making them one of the best air purifiers on the market.
