Twenty years ago, the thought that you yourself could control the air you’re breathing and detoxify your home or workplace was very new. Now in 2019, you can get rid of nearly any pollutant you don’t want around you, and it’s not difficult, there are tons of available options out there. So, which is the one for you?

According to the Environmental Protection Agency (EPA).   New, cost-effective technologies for cleaning indoor air of carbon monoxide and volatile organic compounds (VOCs) are urgently needed. Meaning there is not only a demand for indoor air purification, but that it is necessary [1].

There is no worse feeling than being uncomfortable in the places you spend the most time – your home and work – so don’t let yourself suffer, reap the benefits of an air purifier and literally breathe life back into yourself.

Well, what is an air purifier? How can it help you live a healthier life, free of those ridiculously tiny pollutants? This chart explains how the most common air purifiers work to clean your air by removing things like dust, black mold, carbon monoxide, bacteria, and more!

This is the structure for most common air purifiers available for purchase. Although not always using a UV lamp, the idea is that the air enters the purifier, undergoes a reaction or a filter, and is released as fresh air. There are also units available that disperse bacteria, mold, and odor killing molecules into the air and do not have to rely on all the air in a room circulating through the unit itself.

What is the best air purifier on the market?

By answering your questions, for the remainder of this article I will help you deduce which air purifier is the perfect fit for you, your family, or your workplace.  Here are our top 7 air purifier recommendations.

Are room air purifiers effective?

The short answer is yes. Get the best air purifier for you – if you’re looking for a great price with older technology approved by the FDA, consider a HEPA Air Purifier which are the typical air purifiers that cleanse the air by bringing it in, filtering it, and spewing out new, fresh air.

HEPA purifiers are especially useful for people who are feeling the effects of allergens in the house as well as pollen and other large unwanted pollutants found in the air. Change many of those sleepless nights to full nights of rest.

Consider a Photocatalytic Oxidation Air Purifier if you want advanced technology, fighting not only against dust and bacteria, but also rendering common gases found in the home like carbon monoxide to be harmless.

According to Jeanie Wong , PCOs were initially used to purify air in massive meat processing plants, fighting against bacteria and microparticles in the air before ever being considered for your home [2].

Now, they’re one of the most reliable air purification options around, using a spectrum of ultraviolet light lamps to fight particles as small as 0.001 microns – that’s 300x smaller than the particles a HEPA filter can fight against.

You can’t go wrong. Pick the coverage and the air purifier that suits your style and you’ll be pleased with the nearly instant results.

Are air purifiers bad for you?

Most air purification systems will do their job for you without any extra hassle or worry about adding pollutants or causing you respiratory problems. Research suggests that using an air purifier can improve symptoms for those with respiratory conditions.

That said, be on the lookout for ozone-creating air purifiers. These are designed to suck in old air, cleanse it, and then send the clean air out with new, added oxygen molecules. This is creating ozone.

If allergens are not your problem and you simply want cleaner air, all types of air purifiers could work for you. Ozone air purifiers function by sucking in old air and attaching a new oxygen molecule to the old air, making it fresher [3].

People with respiratory conditions should consult a trusted medical professional before purchasing an air purifier.

Is photocatalytic oxidation safe? [4]

Photocatalytic oxidation is extremely safe although there are still elements being released into the air. The byproducts of the catalytic reaction are CO2 and H2O, which are created during oxidation and released into the air as ozone.

Although not exactly how an ozone-generating air purifier works, photocatalytic air purifiers create their own small amount of ozone that is released after the catalytic reaction takes place. This is the oxidation, as dirty VOCs are broken down, new oxygen molecules are released into the air.

The amount of ozone is very small, and necessary to create the clean air you breathe from the photocatalytic oxidizer.

Depending on the size of the room and the amount of contributing factors to the dirty air (animals, cooking, etc.), you’ll need a smaller or larger unit. It is key to get the correct size for your room because too large a unit could create more ozone than necessary from thinking it has to fill more space.

Can air purifiers make you sick?

No. Air purifiers are meant to provide you with healthier, more sustainable air, not to make you sick. For many with lung conditions, allergies, and issues with sleep, an air purifier has been their saving grace.

Great for people who find themselves waking up with sore throats or getting sick overnight, air purifiers seek to eliminate these issues by improving air quality – giving you a better quality of life.

As written in The Chicago Tribune, you should not think of air purifiers as being a cure to respiratory diseases, but more as a cure to dirty air and useful to improve the room it’s in [5].

With that said, use an air purifier to filter out those pesky odors and allergens that you don’t want floating around your home. That is what can make you sick.

How do I choose the correct air purifier?

Choosing the correct air purifier depends on a few things: the size of the area you want to purify, the type of coverage you are seeking, and the amount of pollutants contributing to air quality.

Consider first whether you want to simply get rid of large particles, like pet dander, pollen, mold and other allergens, or whether you’d like to tackle intrusive gases as well like formaldehyde and carbon monoxide.

A contributor for Forbes writes, HEPA air purifiers are best for eliminating 99.97% of large particles [6]. Whereas you’d need a photocatalytic air purifier if you want the best experience.

The size of the area is important because too small of an air purifier could never extend to corners of a large room, no matter how high you turn it up. Get the right size for the right room.

Sometimes getting a larger air purifier that can cover more than just the room is necessary. For example you may want to get one for a 300ft² even if the room is only 200ft² because there are a lot of pollutants in that area. The advantage of this is getting the maximum coverage without the air purifier working too hard.

Are air purifiers worth it?

Air purifiers shouldn’t be your very last resort, but consider some other options if you’re not fully ready to commit to purchasing an air purifier that will need regular (annual) maintenance.

First consider alternatives like leaving windows open in your home once a day, getting plants, or dusting more often than you currently do. But if you’re quickly running out of options and don’t see improvement in air quality, an air purifier is more than likely a good option for you.

Can you leave air purifier on all the time?

Yes. There is no harm in leaving an air purifier running all day long every day; even on its highest setting most air purifiers use about as much energy as a computer (you’re probably always leaving that on all the time anyway).

If you want to leave it on most of the day and are worried about electricity bills, consider setting the fan to low so you’re conserving energy. By doing this the air purifier will not work as hard, thus cover less of an area, but still function and save energy nonetheless.

Do air purifiers work for mold?

Absolutely. Most air purifiers are fighting against volatile organic compounds (VOCs) which includes mold, dust, pollen, bacteria and so many other things. Even HEPA purifiers, which fight against mostly large particles in the air, cleanse mold and other allergens in the air.

Is there a natural (plant) air purifier?

Yes, there are natural options available. Here are two that I have found to be the most reasonable and useful.

The Chikuno Cube by Morihata International is made from bamboo charcoal and cleans air by trapping any particles surrounding it [7]. It doesn’t circulate air like an electric one might do, but instead traps pollutants and you can release them later by putting the cube in sunlight.

Other options to consider are English Ivy and Peace Lily plants as recommended by with research backed by doctors [8]. Both of these plants are known to clean air that is riddled with common pollutants, constantly leaving air fresher.


We’ve learned quite a few things about air conditions and air purifiers, but the most important is that you can take control of the air you breathe. No more entering your house to weird odors, toxic gases, or stale air, because you can filter these things out of your life.

Remember, you don’t have to purchase any of these items on this list, but do your due diligence and educate yourself on living a healthier lifestyle. And when the time comes, get an air purifier to get rid of the negativity in your life.
