Buyer’s Guide

What should I look for in a good air purifier?


Getting the perfect air purifier for your desk involves finding the unit that will nicely fit on your desk. But not just that, it needs to purify the air effectively and yet also still be portable enough. Also, since it will be sitting on your desk, you want to make sure that it looks good enough to be at eye level. These are all different things to consider when you are looking for a desktop air purifier. Think about functionality, ease of use, and how good it will look. 


The various air purifiers by different manufacturers on the market today, allow you to operate them in most convenient ways. One of these is a smart interface. Look for an air purifier that is easy to use. Sometimes the more technical a unit is, the harder it is to use. Simplicity is key, therefore make sure that you get on whose operation is simple to understand. 

Another advantage of smart features is that they can help you know the quality of the air that you are breathing in. Having smart features may also mean that you can operate your unit remotely possibly through a mobile application. This is great because it means that you will not need to be walking all the way to where the air purifier is placed, but rather just operate it from where you are.  

What is CADR?  

Getting to know your purifier before buying it, will mean getting to know terms like CADR, which refers to the clean air delivery rate. This is important so that you know if it will work in your current space and if it will do the job.  

CADR is measured in CFM which is cubic feet per minute. The filters in the air purifier are tested to see how effective they are in cleaning the air, and the CADR  is measured using three basic pollutant sizes, small, medium, and large. This is done by seeing how well the filters will clean the air of dust, pollen, and smoke.

 These are all different sizes and hence will give you the result as to what the filters can trap and what they can’t. Just remember that these have to be airborne, and air purifiers can not clean the air if the particles have already settled on surfaces. 

Whilst this may seem technical and like it should not concern the end-user, but rather the manufacturer, it helps you know what type of air you cleaner you are getting and you can also then compare different air purifiers. It will also help you know how effective it will be for your situation, knowing that not all purifiers are made equal and that your purification needs differ from the next person. 

CADR is also a great way of keeping a tab on the unit’s functionality without the fluff that usually comes with a lot of marketing campaigns from various advertisers. It is almost like popping the bonnet open to see what is underneath. No matter how shiny the car is, if the engine does not have the right capacity, looks will not matter at all. 

You will usually find CADR ratings for 3 different sized particles. This does not mean that these are the only particles that can be filtered by the unit, but it represents particles in that size group. As a consumer, it is important to realize that airflow and filter efficiency need to be balanced out by CADR

What is room coverage?

The other feature that you need to look for when you are buying an air purifier, is the room coverage that it gives you. This rating shows you how well the air ina certain sized room is cleaned. The room coverage is often measured in square feet or square meters and will help you know about the capacity that the air purifier has. If the room coverage and the size of your room do not tally, it may seem like the unit is ineffective when in fact it simply needs to be placed in a room it can handle. 

Noise level

In as much as the efficiency is important to consider, so is a low level of noise. A noisy purifier can make it very difficult to work with especially in an office environment. A good air purifier should be seen and not heard. Its effects in cleaning the air need to be felt and it should not disturb your peace. Noise level is an important factor to consider. 

Why do I need filters in an air purifier?

The whole point of getting an air purifier is to make sure that it can adequately clean the air, and the filtration process that it uses is a major part of this. This is why it is important to make sure that you have the right filters and that the process can comprehensively cover your room and clean the air efficiently. 

Different models have different filters. One of the key determining factors in choosing an air purifier with the right filters is making sure that you know what sort of pollutant you want trapped by the filter. Some are better suited to trap larger particles than others. Narrow down what type of air particles you need trapped in the filters. 

Air purifiers with a longer filtration process will do a better job of filtering the air holistically rather than simply cleaning it of one or two particle types. Hence you will find some models have 5 in 1 filtration processes. These are not just for show, each step, and each filter has a part to play. 

Accessibility and portability

The manner in which you operate the air purifier is a big determining factor as well. You want to make sure that the air purifier is easy to use. The less hassle the better. It should not need to be rocket science. Whilst manual operation is a good option to have, it should not be the only one available. 

One of the main reasons for getting a desktop air purifier is to make sure that you have a unit then you can easily access. Portability is key. Meaning that it needs to be compact enough for you to fit it on your desk. If it is too cumbersome, it defeats the purpose. 


When you are thinking of buying an air purifier, it is important to know how much it will cost you to run the unit. The initial buying cost is not the only one that you will have to encounter. There is the amount of power that it consumes. If you will be running the air purifier continuously (which is what is recommended for most units) then you will need to know the damage it does on your power bill. The exact amount for this will be determined by your power company. 

The other thing that can drive the price of maintenance up, is the filter replacement cost. Before buying the unit, check to see how often you will need to replace the filters, and if you can get them. You do not want to be stuck with a unit that you can not maintain. A dirty filter is dangerous and needs to be changed, as per direction, on time. 

Most pre-filters can be created once a month and then replaced once or twice a year. The carbon filters will need replacing once or twice a year as well, whilst HEPA filters should be replaced once every year or year and a half at most. The exact amount of time when to do this will be prescribed by your unit manufacturer. Some units have indicators that tell you when to replace the filters.

Final Thoughts

An air purifier is a great addition to any room. It allows you to breathe cleaner air and get rid of allergens that could cause problems. The great thing about the myriad of manufacturers nowadays, is that you can take your pick, and amongst these, is the desktop option. Air purifiers that sit on a desk, are perfect for saving floor space, and also cleaning your immediate surroundings at your desk. 

Take into consideration how big your space is and also the type of purification that you will need the unit to do. It also doesn’t hurt to make sure that the unit looks good. Remember that it will be more visible than most floor units would be. 

Make breathing in clean, allergen-free air less of a chore. Enjoy the benefits of an air purifier that you can easily get to. We hope that the air purifiers that we have reviewed, help you find the best one to suit your lifestyle and your space. Personal preference should also go hand in hand with efficiency and functionality. Happy shopping!
