Are air purifiers a waste of money? It’s a fairly common refrain these days, and there are certainly plenty of critics out there.

That said, many people still find value in purchasing an air purifier—and sometimes it can even be the best choice for improving your indoor air. Let’s take a look at some pros and cons.

Air Purifier Overview

Air purifiers are devices that help remove impurities from the air in a room. These impurities can be anything from pet dander to bacteria, pollen, and even tobacco smoke.

Air purifiers are useful for people with allergies or asthma, as they can help eliminate the airborne irritants that cause these issues. An air purifier can also help reduce household odors caused by things like cooking, pets or smoking.

The best air purifiers can also help eliminate volatile organic compounds (VOCs), which are gases emitted by some household products, like paint and cleaning supplies, that can cause headaches and other health issues.

How do Air purifiers work?

They work by sucking in air from a room, cleaning it, and releasing it back into the room. There are different types of air purifiers, but they all work in a similar way.

Air is pulled into an air purifier through a small vent, usually on the side or back of the machine. This vent often has some type of filter attached to it to collect large particles like dirt, hair, and dust mites before they reach the rest of the machine.

Once inside the air purifier, the dirty air passes through one or more filtering systems that remove harmful particles like pollen and pet dander. These filters also remove odors, gases, and other harmful substances that can be floating around in the air. With many models, these filters are washable or replaceable, depending on their purpose.

Are Air Purifiers a Waste of Money?

The short answer is no, air purifiers are not a waste of money.

Air purifiers remove particles such as dust, pollen, and pet dander, as well as smoke, mold spores, and odors, from the air.

If anyone in your family suffers from allergies or asthma, an air purifier can reduce their symptoms. In addition, if someone in your home smokes, an air purifier will help keep secondhand smoke from lingering in the air.

What is the Main Purpose of Air Purifiers?

The main purpose of an air purifier is to remove contaminants from the air. Most people use them because they want to clean the air in their homes or office, but some also use them to treat certain health conditions. There are many different air purifiers on the market today.

Some types of air purifiers are more effective than others at eliminating certain pollutants from the air. Some types can even remove allergens and bacteria that can cause allergies or respiratory problems!


Air purifiers have many benefits. Depending on the type of air purifier you purchase, you could:

  • Improve air quality in your home. Air purifiers remove allergens, such as dust and pollen, from the air. This can help reduce allergy symptoms.
  • Reduce odors in your home. Air purifiers remove many common odors from homes, including odors caused by pet dander and smoke.
  • Clean the air in a single room or your entire home. Air purifiers are available for purchase in different sizes, allowing you to choose one that fits with your space needs.


Negatives to an air purifier include cost, maintenance, and effectiveness. Air purifiers can be expensive to purchase and maintain.

 Replacement filters can be very costly and some units need the filter changed more than once a year.


It’s pretty clear that air purifiers aren’t a waste of money. They have a host of advantages that more than makeup for their initial cost, with the added benefit of being relatively easy to maintain and operate as well. That doesn’t mean they’re perfect, though. At the end of the day, it’s up to you to decide if an air purifier is right for your needs—and that’s exactly what we’ll help you do.
