Best Desk Air Purifiers for Office

Last Updated July 27, 2021

As the COVID-19 pandemic continues with no end in sight, it has become more crucial than ever to maintain your health and take precautions to prevent catching the virus, even if you have already been vaccinated. There are various ways to do so, from washing your hands routinely and using sanitizers to wearing a mask when going outdoors and avoiding crowded areas.

However, another practical method would be to own an air purifier. With the pandemic forcing us to spend more time indoors and work from home, the air at home can get stuffy or stale after a while. In cases where you need to work in the office, you may be concerned that the air surrounding you is contaminated with pollutants or other harmful particles that could potentially get you ill.

There are several kinds of air purifiers on the market, but this article will focus on air purifies for office desks.

What is an Air Purifier?

Air purifiers, also known as portable air cleaners and air sanitizers, are stand-alone units that are built with air-cleaning technology that are used when minimizing sources of pollutants and diluting pollutant concentrations through ventilation with cleaner outdoor air are insufficient.

How do Air Purifiers Work?

These handy devices operate differently from essential oil diffusers and humidifiers, which add particles to indoor air. Instead, air purifiers sanitize the air from pollutants, allergens, and toxins. This is one step further from air filters, which only remove or trap certain particles.

According to Healthline, “certain versions [of air purifiers] are made with filters to trap particles as air runs through them, while others may neutralize other particles in the air without filtering them first.”

Why Use an Air Purifier in Your Work Space?

A typical desk job requires one to spend at least eight hours a day working. As a result, it is important that you receive decent air quality when you are sitting in the same spot for as long to ensure you are getting enough oxygen for your body to function optimally. Your brain works hard after all, and it needs a good supply of air!

Another reason is that air purifiers can help alleviate certain respiratory symptoms or issues, such as asthma. As high concentrations of fine particles are often associated with health risks- particularly young children, the elderly and those with existing respiratory health problems- air purifiers can assist in reducing such concentrations. According to the EPA, “most air cleaner intervention studies have found statistically significant associations between the introduction and use of portable air cleaners in homes and at least one measure or marker of improved health outcome, although the improvements were typically modest.”

Buying Guide for Air Purifiers for Office Desks


Q. Are air purifiers effective if put in cubicles?

A. Yes, air purifiers can still work optimally even when placed in cubicles. However, the volume of air that is withdrawn and cleansed by the air purifier will vary depending on the obstacles placed around the air purifier, as well as the distance the air purifier is capable of cleansing.

Q. How often should you change the filters?

A. This will depend entirely on the air purifier model and the frequency and duration the air purifier is used. The longer an air purifier is on, the more used its filter will be, and vice versa. Be sure to check the description of the model you are about to purchase to see how long its filter can be used and the typical replacement period and cost.

Q. What is a HEPA filter?

A. HEPA is an acronym for high-efficiency particulate air. So, a HEPA filter is used to trap airborne allergens and pollutants, and offer the highest available particle removal efficiency of fibrous media air filters for a wide range of particle sizes.

Q. What do I need to consider when looking for an air purifier?

A. As each air purifier has its own performances and technical characteristics, you should compare the filtration levels of each air purifier, because this relates to the effectiveness against domestic pollution.

Also consider the surface area treated, as it is necessary to use a device of the appropriate size for the dimensions of the area being treated to ensure optimal air cleansing.

Lastly, you will need to keep an eye out for the types of filters used and the noise level. Each filters has its own unique function and purpose, whereas you may consider one that is quiet to prevent it from distracting you during work.

Q. Are air purifiers really worth it?

A. Yes. As shown in this article, air purifiers in general provide a lot of benefits, and can improve your respiratory health. However, you need to be aware that air purifiers are not meant to be a replacement for your medications; always talk to your doctor before reducing or stopping any medications, and to also receive insights or recommendations on the type of air purifier that you need.
