So How Does the GreenTech Environmental pureAir 50 Work?

The GreenTech Environmental pureAir 50 Small Space Plug-In Purifier is very easy to set up.

You just look at it and you already know how it works. 

You want to know how easy it is?

When you get the package, which weighs around 12 ounces (with dimensions of 7.75 by 4.7 by 3.25 inches), you will see that there is only one item in the box. 

You will only get the plug-in purifier, which is quite small at 4.25 by 3.5 by 2.5 inches.

Now look!

At the back of the product protrudes the plug. It is directly attached to the purifier. 

The plug has two flat prongs.

You just plug it in an outlet and you’re good to go!

By the way

The front has a dial that you could adjust so you could just the appropriate level of purification. 

This way, if you have a smaller space, you can turn it down low. Obviously, you turn it on high when you have a bigger space. 

Check this out:

You can use it anywhere!

The bathroom, the bedroom, your office or the kitchen. 

Just anywhere!

Let me tell you

This product purifies the air in a space thereby removing the stench or any unwanted odor. 

It can also reduce bacteria and viruses. 

I know what you’re thinking

You might get excited that it will work well against SARS-Cov-2, which is the virus that causes the coronavirus disease 2019 or COVID-19. 

There is no proof to that actually.


The air purifier can work against some viruses. At least, that’s a few illnesses off your home. 

It also reduces allergens. 

What’s the magic formula?

It’s actually the combination of activated oxygen and ionization.

The Good

The best part about the pureAir 50 air purifier is the size. 

People always say that bigger is better. But not in the case of air purifier and travel. 

Here’s the deal

It’s so small and light that you can take it with you anywhere you go. 

If you have to go on a business trip, put this air purifier (or two) in your luggage. When you get to the hotel, you can put it in your room. 

At this point in life

You should really be careful!

One valuable lesson we learned from the COVID-19 pandemic is the importance of cleanliness. 

It’s best that you travel with an agent of air cleanliness, too. 

On the issue of size:

Yes, this won’t do in large spaces. 

The maximum air purification it can do is through a space of 352 square feet. 

On the other hand

This is small and inexpensive. 

You can buy a number of these and place them in strategic areas of the house: comfort room, kitchen and bedrooms. 

This will be great in offices, too. 

To be more specific

If somebody in the house is cooking food that has a protrusive smell–not necessarily a stench, just something that you can’t take off your clothes. 

For example, Indian food. They don’t stink but when you cook Indian food, there is an overwhelming scent that is scattered around the house. 

It’s not just that

There are also Mexican food and a number of delicacies that may taste delicious but the smell may not be agreeable to a lot of people.

You definitely should have the pureAir 50 in the kitchen. 

Let’s not forget the pets

If you love pets but live with someone allergic to pets, know that this air purifier can aid that situation. 

Plus, the product removes the smell of pets in the air.

The pureAir 50 also works really fast. 

On to another space

The same could be said about the bathroom. When you go do number two, the smell of the poop could travel around that small space very quickly!

You may also put this in the bedroom and the living room. If you have a large living room, then you can put a few of these in designated areas.


If you’re living with a smoker, this air purifier is a great way to remove the stench. 

You may also take this with you to your office! 

This product also works to remove the stench and bacteria brought by molds and mildews.

The Bad

Since it’s small, you would notice that in just a few months, it would stop working. 

Here’s a picture

When you just unboxed this and plug it in, you’ll feel the difference within an hour–no joke!

However, after a few months, you’ll realize that hours after you plug it in, it won’t remove the smell of the space anymore. 

So, what’s happening?

Since the product it’s so small, the things being filtered will be stuck in it. 

It’s not working because it’s covering the mechanism that purifies the air. 

At least

You can clean it up and just put it back together. 

In addition to that

This small product has some volume on it. 

Don’t get me wrong, it’s not loud. But you’ll be surprised to hear that a product this small can emit that sound. 


Not all people will like the smell coming from this air purifier. 

The item oozes some sort of scent to counter the odor of the space. However, mixed with the odor, not all people will like the smell coming for this GreenTech Environmental product.

The Beautiful

If you can’t have clean air all the time, then you make a way to do it! The GreenTech Environmental pureAir 50 Air Purifier is definitely the way to do that. You can take it anywhere with you because it’s very small. 

It’s easy to use too. Just plug in this great portable air purifier in the outlet and you can have purified air within 30 minutes.

And Does It Work?

It does! But you have to remember that it should only be for small spaces. The maximum space that you can truly optimize this air purifier is just a little over 350 square feet. 

You also need to remember that the product needs to be cleaned every few months in order for it to continue working the way that it should.



  • You can take it with you everywhere
  • Affordable
  • Removes various stench
  • Adjustable dial
  • Convenient to use
  • Works fast
  • Stops working after a few months
  • A bit noisy
  • Smell is not agreeable to everybody


My Verdict

My Rating - 90%


Get purified air everywhere!

It’s not always that you have clean air. You might be faced with a situation where you have to sleep somewhere else, whether it’s a hotel, a vacation house or someone else’s house, you should always be safe.

Take this GreenTech Environmental pureAir 50 Air Purifier with you at all times. You can even take more than one. It’s a great way to really purify the air around you especially when you are in a place that you are not familiar with. You don’t know if the owner of the space cleans all the time.

It weighs less than half a kilogram. It weighs almost nothing! So there really is no excuse not to have clean air at all times. The pureAir 50 is great for the bedroom, bathroom and the kitchen. You can use it in the office, too.

Other Options

For bigger spaces like a large bedroom or the living room, you should try the GreenTech Environmental pureAir 500 Room Purifier. In addition to the activated oxygen and ionization that also works with the smaller pureAir 50, the larger air purifier also features the HEPA carbon filtration.

Moving on, to purify the entire house, you will need the pureAir 3000 Whole Home Purifier. It’s more expensive but you will only need one!
