Why You Should Choose Your Air Purifier Carefully

There are several reasons why you should take care when buying an air purifier. Ensuring that you purchase the product which features the best value for money is a reward in of itself, but there are also a few more tangible reasons why you may wish to pick carefully.


When it comes to products like air purifiers, you are entrusting the appliance with your health. Since air purifiers either filter or alter the very air that we breathe in our homes, a product which features a defect or is simply badly designed may be bad for your health. There is a very real example of this when it comes to air purifiers and it is in the case of ozone air purifiers.

While ozone air purifiers are marketed as filtering your air, in reality, they produce the O3 molecule, which is also known as ozone. It was believed that ozone is a good method to purify the air in your home as it stops germs and bacteria from developing.

Unfortunately, several studies have discovered that an excess of ozone in the house can actually lead to asthma attacks and other deleterious effects.

When it comes to the very air that you breathe, you can never be too careful in purchasing the best product, even if it ends up costing you a little more money. Taking risks with your personal health is simply not worth saving fifty to one hundred dollars.

Beyond the matter of personal health and ensuring you get a good quality air filter, there are also a few reasons which are less dire. For example, you will want to purchase an air purifier with excellent build quality as it will last you far longer than a model which is cheaply made.


Consider the best air purifier as an investment. It is meant to last you for years, even if it does seem expensive upon purchase.

Paying twice as much money for an air purifier which lasts three times as long is a good choice, especially since it is very likely that the more expensive model will do a better job all along.

What To Look For When Buying An Air Purifier

We will now go over our list of features which are the most important when searching for the best air purifier. Of course, the importance of each of these individual aspects will depend entirely on you, the customer. For example, if you live alone and you will only have your air purifier on while you are away at work, noise levels will not be as big of an issue for you.

Gaseous Byproducts

This is one of the most important aspects to search for when purchasing your air purifier. Knowing the type and number of gaseous byproducts being emitted by your air purifier is important because they will have a direct impact on your physical well being.

While most byproducts emitted by modern air purifiers are safe to breathe, there are always models which may slip through the cracks.


You will generally not want to purchase an air purifier which makes use of ozone as its main method of cleaning your air. Ozone is one of the worst gases that can be produced by an air purifier as several studies have linked it to health risks.

It is somewhat counter-intuitive that a product which is meant to help make your home a healthy place is having negative effects on your health.

Noise Level

If you plan on using your air purifier while you are at home, you will find that the noise level will be one of the aspects which makes or breaks your purchase. Since the best air purifiers must be positioned in the location where you would like the air to be cleanest (such as your bedroom or the living room), you must ensure that the amount of sound it emits is tolerable.

While it is a given that your air purifier will emit some amount of sound, there is a certain point where the sound becomes annoying. This is the point at which it goes from being simple background noise which is easy to tune out, to being a very real annoyance. This can hinder housework, reading, sleeping and a whole host of other activities.

The worst part about the noise level of air purifiers is that you cannot tell how loud they are until you install and run them yourself. This is why our top rated air purifiers all feature low noise levels, so they can keep your air clean without being a hinderance.

Frequency Of Filter Replacement

Another important aspect about your air purifier to consider is how often the air filter will need replacement. While this may not seem like so much of an issue, having to replace a filter every week can get annoying and somewhat pricey.


While most modern air purifiers feature filters which can last for a long time, the quality of products can vary somewhat drastically and you are better off being safe.

The frequency with which you will have to replace your air purifier filter is highly dependent on the type of air purifier you choose to purchase. Certain types of air purifiers, such as ion air purifiers, will not require you to replace the filters as they do not make use of filters.

However, the vast majority of the best air purifiers will tend to use at least one type of filter system combined with other forms of technology. This is due to the reason that filters are still the most effective manner of capturing particles in the air.

Most HEPA filters will typically last you at least a year, so you will not have to maintain a HEPA air purifier quite so much. Certain models even use filters which can last for several years, up to a maximum of four.

HEPA filters are not overly pricey, thankfully, but we still recommend ordering your new filters in advance when you know you will have to change them soon. This way, you will not be using an ineffective air purifier with a clogged up filter.

Electrical Consumption

The next aspect to look out for is how much electricity your air purifier uses. As air purifiers tend to be on for long periods of time, you will find that purifiers which are electricity hogs will end up costing you quite a bit on your electric bill in the long run.


While high consumption models will typically work faster, you will want to find the right balance between electric consumption and effectiveness.

It also helps to consider the age of your air purifier when attempting to measure its electrical consumption. If you are using an air purifier which is fifteen years old, it is almost guaranteed that it will use more electricity less efficiently than a model which was released recently.

While this is not the only consideration that must be made when comparing two air purifiers, it is the only aspect short of the price that must also be considered in your budget.

Visual Appeal

Another important aspect to consider is the aesthetic value of your air purifier. While this may seem like a small consideration when compared to the other aspects, finding an air purifier which blends well with the decor of your home is a definite plus.

For example, if your home is furnished in darker shades, such as mahogany and rich crimsons, you will not want to purchase an air purifier which is your typical off white as it will clash.


It is also important to find an air purifier which will fit in your home. If you find that space is at a premium in your home, you may wish to consider purchasing a portable air purifier. While portable models of air purifier are certainly less powerful than full size wall mounted models, they are also more convenient, as you may travel with them.


You may also use them in homes where large air purifiers would be impractical.

When considering the size of your future air purifier, it helps to measure out the area in which you intend to place it. It would be quite a shame to find out that your new air purifier is just slightly too large to fit in its intended location, so measure and then double check.

Ease Of Installation

One last aspect to look for when purchasing your air purifier is to ensure that it is easy to install. If you do not want to pay an outrageous price for professional installation, simply find a model of air purifier which can be put up as long as you have a little bit of DIY experience.

In addition to saving you money, you will learn more about how your air purifier works through installing it yourself. It may not be the most crucial aspect, but it can be a good tiebreaker between two very similar models.
