Danny as been writing about air purifiers for 10+ years. He is a major fan of home technology, which makes him the perfect person to test and evaluate products for HouseFresh

With most of the world’s population in lockdown, we’ve all had to make some major adjustments to our lives. One aspect, in particular, that has undergone a lot of change is where and how we work. For those of us that are now working from home, we have seen the time that we spend indoors dramatically increase. And while we might have seen images of dreamy work-from-home setups, the reality for most of us is a makeshift desk crammed in wherever we can manage, with even a nearby window being classified as a luxury. 

If your new ‘office’ has you confined to a storage space or cowered in the corner by the kitchen, then chances are you’re feeling the effects of poor air quality. From office pets, roaming cooking odors, or perhaps stale air built up from a houseful of people, you can expect to find up to five times more air pollutants indoors.

Studies have found that poor air quality can negatively affect your productivity, on average resulting in a 3% to 5% drop in efficiency

Having read this, you’re probably itching to leave your desk and get outdoors. As that’s not always an option, we’ve researched the best air purifiers that will sit on top of your desk and help solve your air woes. 

To compile this list, we took into account the size and noise of the purifier, so as not to impose on your space or add yet another distraction to your new work environment. By looking through consumer reports, we’ve included a variety of purifiers to suit different-sized rooms, with the ability to tackle a range of pollutants, including dust, odors, and viruses to ensure each product was tried and tested by real people leaving genuine, positive reviews.

1. LEVOIT Core P350

LEVOIT Air Purifier for Home Allergies and Pets Hair, H13 True HEPA Filter with ARC Formula for Bedroom, 24db Remove 99.97% Odors Smoke Dust Mold Pollen, Core P350, Grey

With the LEVOIT Core P350, you can get a personal purification unit that can keep your office fresher no matter if it’s just you who uses it or if your pet decides to come in. The ozone-free air purifier features an H13 True HEPA that reduces up to 99.97% of pollutants. Before anything can get to that, however, the pre-filter goes to work capturing floating pet fur, dander, hair, fibers, and lint thanks to its updated fine non-woven fabric.

This high-grade filter also utilizes modified activated carbon with specialized AirReComposition that focuses on removing harmful substances. This includes the likes of gases and odors. Air is refreshed through absorption and decomposition.

With its QuietKEAP Technology, you can run the unit during work hours in the office and not be disturbed as it typically doesn’t produce any noise louder than a common fan. Additional features include the ability to turn off the display and even a timer function. It can be set for two, four, eight, or 12 hours.

With the activated charcoal filter, the unit can also reduce those unwanted odors. This leaves you with a room that is healthier and smells better in the long run. Before any of that happens, the quality pre-filter is in place to capture those larger particles like pet hair and even does well at extending the life of the HEPA filter. Since it does all of this, it may remove surface dust, cutting down how often you have to clean the room.

Controlling the unit is rather simple. There are three fan speed modes as well as an Ultra-Quiet Sleep Mode function so you can use it at all hours of the day or night. Also, if you don’t want to worry about the UV-C light, you can turn it off on the same panel.

FAQs About Air Purifiers for Desks

Will an air purifier protect me from COVID-19 in my home?

Air purifiers can indeed reduce airborne contaminants that can invade a home, and this includes viruses as long as it has the proper filter system in place. However, on its own, it is not recommended as enough protection to completely ward off COVID-19 indoors.

So, along with a quality air purifier, sanitizing practices recommended by the CDC should still be followed. When those are followed, the use of an air purifier becomes part of an overall plan to maintain protection for you and your family.

Do I need an air purifier?

Air purifiers are extremely useful since there are several sources of indoor air pollution that we’re exposed to daily. Inside the home are a complex mix of agents from both outdoor air and indoor sources, which means there is a variance in how much they can potentially affect your health.

An air purifier is ideal for minimizing or eliminating these issues.

Do I need an air purifier for each room?

Whether or not you need an air purifier in every room depends on the size of your home. For example, a smaller apartment unit or even a single-story home might not require multiple units to get full coverage. At the same time, the size of the rooms and hallways themselves should be kept in mind.

Yet another key consideration is the unit itself. Is it designed to handle more than 800 sq. ft.? These larger units can manage homes easily without resorting to buying a purifier for every room. The fan speeds come into play too as on higher settings, units can generate more airflow.

Which Air Purifier Is Best for You?

Many air purifiers are suitable for a desk setup so that you can keep your office area fresh and smelling good without any bulky equipment getting in the way. Another great feature is that they won’t be such an eyesore when you place one in your room. Many of these offer a stylish design too along with being compact. This way, you can set it up on your desk and not have it stand out too much.
