Guide to Office Air Purifiers

Are you sure that the air you are breathing in your home and office is clean and bacteria-free? If you have a home office, then you really need to consider an air purifier that can filter allergens and other airborne contaminants from the air so you can work comfortably while breathing fresh air. According to the United States, Environment Protection Agency, the air quality inside our homes can be five times more polluted than outdoors.

The reasons for this is the way buildings are constructed and various stuff we bring in our homes that release harmful contaminants. An air purifier works great in this situation, and getting one won’t just prove good to your health but also allow you to work in a healthy environment.

However, the major issue most people face while buying an air purifier is deciding which one to go for as there are several types and thousands of options available in the market. If you are also facing this problem, then don’t worry, we have got you covered. In this article, we have put together a guide that will help you find the best air purifier for both your home and office. And, we have also rounded up some of the best office air purifiers so you can decide better by comparing their features with each other.

Let’s get started!

How Does An Air Purifier Work?

An air purifier’s mechanism is quite simple. It uses a system of internal fan that sucks the air in your home through several filters and removes the harmful contaminants like bacteria, pollen, and dust. Then it circulates the clean and purified air back into your home. This process is repeated several times a day, so you can always breathe fresh air.

Benefits of Air Purifiers

If you think that an air purifier is not much important for your home or office, here are some benefits to change your thinking:

  • It ensures that you are breathing clean and contaminant-free air.
  • It removes unpleasant odors like the smell of cooked fish or burnt food.
  • If you have pets, you should definitely get an air purifier for yourself because it traps airborne allergens released by your pets.
  • It helps neutralize the smoke.
  • Regardless of how clean your home is, there will be dust. An air purifier helps trap that dust before it settles so you don’t have to get in every corner of your office to clean it.
  • A quality air purifier is capable of removing up to 99% of airborne bacteria, including mold spores, pollen, and others.
  • If you feel uncomfortable breathing in your office due to seasonal allergies, you can use an air purifier to combat seasonal allergens.
  • It keeps your lungs healthy.

Types of Air Purifiers

If you have been looking for air purifiers for quite some time, you would know that there are lots of different air purifiers available in the market. Although the choices are unlimited, you’ll be happy to know that there are only four basic types of air filtration that all the air purifiers use:

1. HEPA (High-Efficiency Particulate Air) Filtration

This filtration system is acknowledged worldwide and considered the gold standard for air purification. It consists of a thick filter paper that traps contaminants and cleans the air. Several filters use HEPA acronym, but you should only opt for an air purifier that has a label of “True HEPA Filter” because it is certified to remove 99.97% of airborne contaminants as little as 0.3 microns in size.

2. Ionic Filtration

This filtration system sends out a cloud of charged ions into the air that gets latched with the airborne contaminants and cause them to fall onto the surface. Some air purifiers even have a process to collect those fallen particles. This is done with the help of an electrostatic collection plate that attracts fallen contaminants and eliminates them from the room.

3. Carbon Filtration

As the name suggests, this type of filtration uses a special form of activated carbon that consists of several tiny absorbent pores. These pores work great in trapping gases, odors, and fumes. However, air purifiers with carbon filtration do not remove harmful particles that cause health issues. They only get rid of the particles that cause bad smells.

4. UV Light

These type of air purifiers emit UV-C band of the ultraviolet spectrum that attacks pollutants, unlike other purifiers that pass them through a physical filter. Wondering if this UV band is safe for humans? Yes, it is absolutely safe and doesn’t cause any side effects.

UV-C band destroys the DNA structure of the airborne bacteria and viruses inside your home, providing you clean and sterilized air to breathe in.

Some units also combine all these technologies to build a stronger air filtration system.

All these types can be seen in two different versions:

Classic Version

Classic air purifiers do not provide any information on what impurities they have actually removed from the air. All you have to do is turn your air purifier on and trust that it is working. You can check out its filter after using it for one or two days – if it’s getting dirty, it means your air purifier is operating perfectly fine. Some of the classic ones are also equipped with digital controls and air quality sensors that allow them to do the job much more efficiently.

Smart-enabled Version

Smart air purifiers come with a mobile application that provides you with all sorts of information on how well it is cleaning the air. Some air purifiers even reveal what pollutants they have removed, enabling you to track the air quality right from the dedicated mobile app. Lots of additional is also provided that you simply can’t get with a classic air purifier.

However, smart-enabled air purifiers come at a cost. So, if you are looking to get one, you should be ready to spend more.

Things to Consider Before Buying an Air Purifier for Your Office

Operating Costs

Before purchasing an air purifier, you should know that there are some annual operating costs of about $150 to $200, depending on the type you choose. Suppose you buy an air purifier with carbon filtration, you may need to replace its carbon filters every three or four months and its main filter yearly. Some air purifiers with HEPA filters have a pre-filter that captures large airborne particles before they reach the HEPA filter, saving you those extra costs.

Noise Control

This is an important consideration if you will be using an air purifier in your home office. Many air purifiers create quite a loud noise that can divert your concentration from the work you are doing. This is why we recommend you to buy a larger unit and turn it to the lowest setting for better performance and noiseless working. It is a one-time investment, so if you are looking for a long-term device, a larger unit would be your best bet.

Energy Consumption

To cut costs, you should look for air purifiers that are Energy Star certified – these units are much more energy-efficient as compared to regular models.

If you are looking for a portable air purifier, then ionbox by IonPacific is a great choice. It is a mini, USB-powered travel purifier that doesn’t include any filter at all. It is just an ionizer that emits clouds of charged ions around you to reduce airborne contaminants. Although it doesn’t collect the contaminants into a physical filter, it does a good job of providing you fresh air to breathe in.

Negative ions that it emits are also known for improving mood and concentration, which means you can feel more motivated while working in your office.

RabbitAir MinusA2 Ultra Quiet HEPA Air Purifier 

Due to its wide range of features and massive cleaning power, RabbitAir MinusA2 Air Purifier doesn’t have much competition in this price range. Unlike most air purifiers, this one offers a 6-stage purification process that provides the cleanest and freshest air possible. The process includes a pre-filter, medium filter, BioGS HEPA filter (an extra-long life version of True HEPA filter), Carbon Filter, Customized filter, and an Ion generator.

If you are a fan of customization, you will love to customize its front panel (color and/or design). However, the only downside it has is its high price. But, if that’s not a problem for you, we highly suggest you select this one for your office.

Winix 5500-2 Air Purifier with True HEPA

The feature that helps Winix 5500-2 outstand other air purifiers on the list is its patented PlasmaWare technology. This amazing technology provides the same benefits as an ionizer but doesn’t produce harmful ozone or side effects.

Its filtration system includes True HEPA filter, UV-C light, and carbon filter. It is suitable for a medium-sized office (up to 193 sq. ft.). If you plan to move your air filter and change its location frequently (normally you wouldn’t), its vertical and lightweight design won’t create any problem for you.

However, the only objection by many users is the plastic smell that it emits during the first two days of use (48 hours). It isn’t a problem, but if you are extra sensitive to odors, this might be an issue for you (in the start only).
