Since so many of us have recently made the transition from the luxury of an air-conditioned office to a home office or living room as our workplace, you may not be aware of the difference in air quality that can come with this change in environment. Unfortunately, most people are not breathing as much fresh air as they should be and are unaware of the harmful toxins that can plague these spaces. To remedy this, an air purifier could be your best chance of improving the quality of the air in your environment, leading to better, fresher air.

A typical household can harbor pollutants such as pet dander, mold spores, and traffic pollutants. Additionally, cooking food can create unwanted odors and harmful VOCs. Unfortunately, this air doesn’t stay in one place and with more people in your household, many people may be breathing the same air for extended periods.

Breathing VOCs can cause some undesirable side effects, such as: 

  • Labored breathing
  • Fatigue
  • Lethargy
  • Headaches
  • Allergic skin reactions

Investing in a good air purifier to cut down on any harmful chemicals, smells, bacteria, and other contaminants floating around you while trying to work is a great idea. However, you will want to make sure you find a quiet model so the noise doesn’t distract you. You’ll also want to consider purchasing one suitable for the size of your space, so remember to check CADR ratings.

We’ve analyzed consumer reports and reviews composed of real feedback from users and ranked based on specific features and effectiveness. This way, we can ensure this is a reliable list of the best models to choose from for your home office.

FAQs About Air Purifiers for Home Office (Small and Large)

What do square footage ratings mean?

When you’re shopping around for an air purifier, among the many features you should consider before buying is the square footage rating. This will determine if you’re getting the appropriately powerful unit for the room you wish to use it in.

Square footage rating is simply based on the area which the unit in question can perform efficiently in. This usually includes calculating how many single air changes it can make within an hour in a particular room size. In these calculations, it’s normal to go off the assumption that the room in question has an 8ft. ceiling.

What are the benefits of having an air purifier in an office?

One of the main benefits of having an air purifier in an office is the same reason it’s beneficial to have one at home: healthier and cleaner air. A good purifier is wonderful at deterring certain viruses and bacteria that can linger in the air. In a business setting, no matter how spacious or small your workspace is, airborne particles can quickly float around and spread illnesses. The right air purifier will capture those particles and reduce the likelihood of everyone in the office getting sick.

There are additional benefits that stem from capturing harmful airborne particles. Fewer illnesses getting spread means fewer people getting sick, which can also mean fewer employees taking sick leave. Productivity can increase from there.

How much does it cost to run an air purifier all day?

The cost of running an air purifier throughout the day depends on the purifier itself. Many have an Energy Star rating, which is a great indicator to show that they don’t consume as much energy so they won’t cost you much in the long run.

Generally, you’re looking at a power consumption of as low as $0.05 per day and up to $1.00 per day. You can easily check with individual air purifiers to get a more specific idea of their energy typical energy consumption.

Which Air Purifier is Best for You?

Offices large and small can benefit from having a quality air purifier. An office environment can be a breeding ground for airborne particles that carry viruses and bacteria, which can allow illnesses to spread far more rapidly. So, an air purifier can reduce those harmful pollutants and the air is cleaner and healthier for everyone.

Besides that, an air purifier can simply freshen up an office, removing any odor-causing particles as well as other microscopic airborne issues such as pollen and dust. The environment overall can be more comfortable to work in.
