Do I Need an Air Purifier?

Air purifiers do wonders for the air quality of your home. By filtering all of the allergens and other irritating particles that are in the air, an air purifier grants you clean, fresh air, even when you are indoors.

Just about everyone needs an air purifier these days, as pollution, and breathing illnesses are both on the rise. Air purifiers alleviate these issues of our modern world, helping to combat our allergies, asthma, and more.

Today we will share with you the reasons why you really should go out and buy an air purifier sooner rather than later. We will do so by telling you what they do, how that helps you, and what each kind of air purifier you come across will do.

Do Air Purifiers Really Work?

Most of us have heard of air purifiers, but many of us haven’t gone as far as to buy one, at least not quite yet. How many of us have considered buying one, but simply been unsure of what they did? How many of us wonder if air purifiers even work? How many of us have been scared off with some of the prices out there? Today, all these answers will be answered, and we hope to leave no stone left unturned.

Are You Waiting Until You Have A Breathing Problem To Purchase An Air Purifier?

A common myth around air purifiers is that you need to have a problem before you can benefit in any way from having one of these air cleaning units. This is very much false, anyone who has lungs and has to breathe to survive can benefit from owning one of these remarkable machines. (And we hope everyone reading this can breathe) This myth likely began with people buying air purifiers to combat their breathing difficulties, which they do do. Air purifiers are great for people with asthma, allergies, and even for people who have smokers in their house or apartment.

Air purifiers clean the air of the room you run them in. This is achieved by the air purifier’s running the room’s air through its various filters. As the air passes through your unit’s filters, microscopic (and oftentimes visible) particles are captured within the air purifier. For those of us with allergies, this is good news, because air purifiers can capture allergens like dander, pollen, and dust, HEPA filters are the best at this. By removing these allergens, you are ensuring yourself a good night sleep, even though the worst seasons for your allergies. Better yet, you don’t even have to put in much work to yield such a glorious result.

VOC’s – What Are They?

In fact, some air purifiers even capture airborne chemicals called VOCs which are in every household and can cause illnesses after prolonged exposure (i.e. sleeping in a freshly painted room). Volatile Organic Compounds (VOCs for short) are chemicals that are released by paint, cleaning products, aerosols, and more, and they are known to cause a whole slew of issues. These issues are all brought about because your body wasn’t made to live in an environment with VOCs, and therefore cannot handle them. A little probably won’t hurt you, but we still recommend playing it safe, this is your life we are talking about here!

I’ve got a whole article that’s all about VOCs, so you can read up on them here.

What Does An Air Purifier Cost?

For those of you who found themselves suffering from the sticker shock of air purifiers, we have good news. We recommend you read our piece on affordable air purifiers before making your purchase, as it will provide you with some guidance. Cheaper options are not always the best, but they can be a great starting point. A cheap air purifier will introduce you to what air purifiers can do, and you will gain a respect for how much they can help you, think of them as a cheap trial that you can have to test the power of clean air.


Yes, air purifiers can do exactly that. Depending upon the odors you would like cleaned, there is an array of options out there for you. You can go all out and get an air purifier with an impregnated charcoal filter to sift out most any offensive odors out there. In addition to this, you can purchase an air purifier with a built-in dehumidifier, which can also reduce odors. Dehumidifiers are great for mildew-ey odors, since they remove the moisture from the air, thereby eliminating the environment mold, fungi, and mildew thrive in.

For more information on dehumidifiers, check out our article that takes a closer look at air purifiers with built-in dehumidifiers. A lot of odors are actually linked to high levels of humidity, which, as we previously pointed out, has its own set of issues. Your home’s humidity ought to be between 30 and 50 percent, and a dehumidifier can help you achieve this sweet spot.

If you don’t want to go all out with your odor control, just a normal air purifier can reduce some of your home’s strange smells, and HEPA filters will do an even better job than that. Ideally, we recommend an air purifier with both an impregnated charcoal and a HEPA filter in order to eliminate odors. However, you can mix and match as you will, depending upon your needs. There are many different types and combinations of filters out there in the various air purifiers, so you are likely to find your perfect match.


Air purifier in the bed room

Yes, and they work very well in many different situations and households. Air purifiers work to mitigate the particles in the air, which can be harmful if left untouched. These air cleaning machines wipe the air clean of all of the particulates which accumulate inside of your home, which can cause your allergies to flare up.

Air purifiers capture all the particles in the air which would otherwise end up settling on your tabletops and window sills, requiring a rigorous dusting routine to keep up on. Rather than waste countless hours over the course of the year dusting, you can invest in an air purifier, and reap the time benefits. For more information on this, check out our article which answers the question “Do Air Purifiers Reduce Dust?”

All of this attests to the fact that the air purifier is doing its job, and is doing it very well. If cleaner air, and a cleaner room isn’t enough evidence for you, the filth locked into your air purifier’s filter should prove its work. The thick gunk which will be stuck in the filter would have otherwise been in your lungs, or on your countertops. Either way, it’d be best if you just got an air purifier to take care of the mess instead.


There are several different air filter types and these are some of the common types you may see:

-Fabric Filters

Fabric filters are filters that are made out of fabric, much like the air filter in your car. They are the most common type of filter out there and can be disposable, or washable, depending on what the manufacturer says.

-HEPA Filters

HEPA filters are special air filters that are growing more and more common in air purifiers nowadays. These filters can sift out more than 99% of the particles in the air, which is better than non-HEPA filters can do. They can capture allergens, odors, and pollen, which can be very beneficial.

-Pre Filters

Pre filters are super important if you don’t want to replace your air purifier’s main filter as often as some models require. A pre filter works to capture all of the larger particulates in the air, like dust bunnies and pet fur, saving your main filter from clogging prematurely with debris that it wasn’t specially designed to filter out. This means that a pre filter increases your main filter’s lifespan. And the best part of this is that these filters are usually washable screens, which don’t need to be replaced. All you need to do is wash away the junk, and you’re back in business.

-Carbon Filters

Carbon filters are made out of charcoal, which is either activated carbon or impregnated carbon. This just means that they are treated with either steam or steam and special chemicals (activated carbon and impregnated carbon respectively). These filters filter out things that normal filters miss, which includes odors and airborne chemicals, which can be harmful.

We recommend finding an air purifier that has a pre filter, a HEPA filter, and a carbon filter (preferably impregnated carbon) for the best results, and cleanest air. To learn more about air purifier filters, check out our article “How Important Are Air Purifier Filters?”

Frequently Asked Questions

Why Should I Buy an Air Purifier?

Why shouldn’t you? (We jest)

This truly depends on where you live, and your health needs. We highly recommend using an air purifier to those of us who live in cities and suburbs in order to combat all of the gross stuff in the air around us. We also recommend purchasing one if you suffer Every. Single. Snotty. Spring Fever in agony as you (literally) blow your way through boxes of tissues.

What is the Difference Between an Air Purifier vs. a Dehumidifier?

An air purifier does just that: it purifies the air. A dehumidifier on the other hand simply takes moisture out of the air. Dehumidifiers do help with allergies since many allergens thrive in humid areas, but they do not clean the air itself. There are air purifier machines with built-in dehumidifiers, which can equate to waging nuclear war with your allergens. These combo units will do wonders to your home’s air if you live in a humid area, or have humid rooms in your home (like a bathroom and kitchen).

Do Air Purifiers Help with Allergies?

YES! Many people who buy air purifiers do so simply to fight off their allergies. These miraculous little machines grant people who are plagued with allergies a place of refuge where they can finally recuperate after particularly nasty times. It is recommended that you pay a little extra and buy an air purifier with a HEPA filter if you are buying one to combat your allergies.

Where Can I Find Air Purifiers for Sale?

Air purifiers are sold just about everywhere nowadays. You can find air purifiers online or in many home improvement and department stores. You can even buy used units online, or at garage sales.

What is an Ozone Generating Air Purifier?

These machines work like normal air purifiers, by with one major caveat, they also release a gas known as ozone. Small amounts of ozone are not dangerous, in fact, that clean smell you smell during a lightning storm is actually ozone! Air cleaners with ozone generators are great for sterilizing a room, but you had best keep the room vacated.
