Do Air Purifiers Work?
Before we discuss if you should get an air purifier for your home, it’s best if we first tackle the question about if air purifiers really work or not.
In order to answer that question properly, it’s important for you to know that according to the United States Environmental Protection Agency the air quality inside our homes is up to 5 times more polluted than the air outside.
That fact is mainly due to poor ventilation, chemicals contained in household cleaners, mold spores, bacteria, and allergens that get tracked inside.
So what do air purifiers do?
The way in which an air purifier works is by stripping the air of these bad airborne contaminants.
The majority of air purifiers work in one of two ways:
- Using a HEPA filter, which sucks in particles and traps them so they cannot float back into the air
- Using an Ionic generator, which emits negatively charged ions into the air that latch on to toxins and cause them to fall from the air
Air purifiers that are fitted with a HEPA filter are able to capture 99.97% of particles that are as small as 0.3 microns. This includes most allergens, many bacteria, and some viruses.
The pollutants get collected inside a dense filter that’s interwoven with thin fibers. This design traps and locks the particles in place so they can’t escape.
An air purifier that uses an ionic generator (also known as an air ionizer) works in a different way to purify the air.
That basic idea behind how does an air ionizer work is that it electrically charges the air so that pollutants fall onto the floor, which then has to be vacuumed up.
Some ionizers include an electrostatic collection plate to collect these toxins, but it isn’t always 100% effective. See our article on ionic air purifier vs HEPA filter here, to learn more about the differences.
Regardless of the type of air purifier you buy, both types work to cleanse the air around you.
By removing harmful particles from the air, these contaminants don’t have the opportunity to get inside your lungs as you breathe.
The less bad particles you inhale, the healthier you stay.

Are Air Purifiers Worth it?
An air purifier is worth it because it can remove allergens and other pollutants from the air. There are numerous health benefits associated with using air purifiers and the results vary from person to person and depend on the types of pollutants indoors. Overall, air purifiers are worth the money.
Do I Need an Air Purifier?
The information above helped answer the first part of the question, “Are air purifiers a waste of money?” Clearly, they’re not a bad investment if you want cleaner air around you.
But, do you really need one?
The answer to this question depends on a few things.
For some people, an air purifier is a great device that helps promote better health.
For others, the benefits are not as noticeable.
The information below should help you figure out which category you fall into and if you should invest in getting an air purifying device.
Yes, get an air purifier if:
- You’re like the other 50 million Americans that suffer from allergies or have asthma. You’ll notice outstanding relief in your breathing when using an air purifier.
- You or someone in your home gets sick easily or is prone to infections. One of the best air purifiers for viruses can trap harmful pathogens and microorganisms that cause sickness.
- You want to ensure that your body stays free from airborne toxins and you want to be as healthy as possible while inside your home. An air purifier can help with that.
No, don’t get an air purifier if:
- None of those situations above sound like you. Most likely won’t notice a big change in your health since you’re not affected by allergens and other contaminants like many other people.
Another option you can consider is an indoor air quality monitor. These units do not clean the air like an air purifier but just measure the various pollutants inside a room. That way, you can know how good or bad the air quality is before you invest in a new air purifier. Check out our air quality monitor reviews guide for more details on these units.
Hopefully, this information has helped you realize if are air purifiers worth it or not for your own situation. If you’re still not convinced, take a look at the other topics mentioned on our about air purifiers page to learn more about this technology.
Affordable Options Exist
Another thing worth mentioning is the fact that many people think air purifiers are expensive to own and operate. However, that’s simply not the case.
There are many low-cost options that are excellent at cleaning the air.
