Desktop Air Purifier

A desktop air purifier helps you to enhance the quality of air in your surroundings. If you’re looking for the ideal air purifier for your home or office, there are numerous considerations to consider prior to purchasing your preferred device.

Do You Need an Air Purifier for Your Office?

A national survey conducted by Klepeis et al. in 2001, the average American will spend more than 87% of their overall time indoors either at the office, at home, or even in public buildings such as institutions of higher learning. It’s important to understand that the quality of indoor air can be more than 5 times contaminated compared to outdoor air. Lack of ventilation and adequate circulation of fresh air in the office or at home causes accumulation of contaminating particles and pathogens.

Over-exposure to these substances can cause dire health problems. These pollutants include allergens, viruses, mold, bacteria, and volatile organic compounds. The ideal method of regulating the quality of indoor air is by eradicating the source of contaminants and ensuring that the room is well aerated. However, sometimes opening your home or office windows for fresh air could be impossible.

Still, your home could have air circulation limitations perhaps as a result of a poor floor plan, or probably your home lacks enough windows for adequate air circulation. In such a case, many people are likely to embark on research to establish the best air cleaning gadgets such as air conditioners and purifiers to manage and enhance the quality of their indoor air.

In order to establish the ideal air purifier for your office or home, you should figure out why you need the air purifier. Do you need it for the elimination of pollen? Are looking for an odor management gadget? Or are you seeking for the perfect device to destroy germs? Depending on your needs, you can choose an ionizer air purifier or a HEPA purifier.

HEPA filters utilize air circulation via a fine mesh to filter and confine small particles such as pet dander and hair, pollen, smoke, and even dust mites. This way, they allow you to breathe clean air. If you are seeking for an air purifier that will help you eliminate germs, find an air purifier that uses ultraviolet technology. It destroys even the tiniest bacteria to enhance your health and improve the quality of the air you breathe.

The size of your room should determine the size of the air purifier you purchase. Remember, each air purifier comes complete with room dimensions. Use the gadget within the right specifications for ultimate performance. Following advanced technological improvements; you can purchase a silent air purifier allowing you to utilize it at home and within the office environment without getting disturbed or disturbing your colleagues. Before choosing your gadget, confirm that it offers a variety of settings. This way, you’ll be able to switch off the gadget when it’s not in use to conserve energy.


How do desktop air purifiers function when it comes to improving the quality of air? This question lingers in the minds of many people. A desktop air purifier comes with ultra-fine filters which sieves contaminants and traps them within the filter. The slight noise that the gadget produces emanates from its fan.

However, modern purifiers are specially designed to produce little to no noise. The fan circulates air across the filter, directing all polluted air on one part of the gadget while clean air exits through the exhaust side and is released back to the environment for you to breathe.

What About the Ionizer?

If your desktop air purifier comes with an inbuilt ionizer, it produces negatively charged ions which circulate through the air, locates and latches on positively charged small particles and dander, traps, and filters all contaminants to ensure that the air you breathe is of high quality. Therefore, you can manage serious allergies with good quality air purifier with a great filter and a robust ionizer.

Technology has allowed manufacturers to combine various technologies to enhance the quality of their air purifiers and enable them to deal with multiple pollutants. Many advanced and modern air purifiers are more expensive and non-portable since they accommodate various air filtering technologies. If you are looking for a desktop air purifier, you should beware of this factor as moving big and bulky gadgets from one area to another can be challenging.

How Effective are Compact and Portable Air Purifiers?

Technology has allowed manufacturers to design air purifiers in different forms and sizes. There are numerous air purifiers designed to be portable and compact allowing you to utilize them on your desk at home or in your office. Some compact gadgets come in the form of air fresheners which you can easily plug in a power outlet in your room. If you prefer small air purifiers, you want to ensure that they are efficient enough for the size of your room. Often, the smaller an air purifier the less effective they are.

What to Consider when Purchasing a Compact Air Purifier

Ensure the gadget has robust filters at PM10 / 2.5. A HEPA filter falls in this category. Further, the filters should be easy to change on a regular basis to maintain their efficiency. Remember, even genuine HEPA filters can have limitations when it comes to the magnitude of particles they can filter. For instance, HEPA filters are not ideal for filtering certain bioaerosols and volatile organic compounds.

Stay Away from Ionizers and Ozone Generators

Some air purifiers that are as cheap as $20 can easily be utilized to ionize air in your surroundings. However, this air cleaning technique is not ideal. This is because the pollutants stick on various surfaces such as file cabinets, table tops, and chairs. A big percentage of these units generate ozone which is a harmful byproduct known to cause lung irritation.

Ionizers and ozone generators are often fanless which makes them more silent. Manufacturers promote them as the ideal gadgets for use in the office seeing that they don’t produce any noise and cause no disturbance at the workplace. However, these gadgets are highly likely to generate irritants within a restricted space. Where possible, avoid ionizers and ozone generators.

What are the Cons of Portable Air Purifiers?

It’s important to note that even the best HEPA filter requires proper handling and maintenance to function well. Dirty filters, for instance, can contaminate the air rather than cleaning it. Change your filters regularly to avoid build-up of dirt and contaminants.

According to a study conducted to establish the effectiveness of air cleaners and filters for respiratory-related allergies established that ionic air purifiers can generate a great percentage of submicrometer contaminants. J.L. Sublett conducted the study.

This was attributed to the interconnection between the ozone and VOCs generated by the ionizers. Rather than eliminating contaminants in your office, you could be more exposed to pollutants generated by ozone byproducts.

Which is the Best Desktop Air Purifier for Your Office or Home?

In order to purchase the ideal air purifier for your space, you need to consider the magnitude of your contamination and match the same with probable solutions. Decide consciously on the size of the gadget in relation to the room you want to be filtered and then exercise vigilance in regard to replacing air purifier filters on a regular basis. Today, the market is afloat with numerous air purifiers and choosing the ideal one can be a daunting task. Below are some of the most robust air purifiers.
