If you live with seasonal allergies, pets, or both then you’ve probably considered purchasing an air purifier. Or perhaps you already have an air purifier and you’re looking to upgrade. Whether you are a first-time air purifier owner or a long-time power user, it’s important to do your due diligence before jumping into any new appliance relationship.

There’s little worse than buyers’ remorse, and when you’re talking about an appliance that can have a significant effect on your air quality, it’s important to take your time and consider all the options before coming to a decision.

2.Bissell air320

In the first line of this air purifier’s defense is the permanent fabric pre-filter. Its role is to hold back bigger particles also protect the high-efficiency filter. Other than that, it also acts as the front cover of the device. Bissell recommends vacuuming it occasionally to remove dust from the front panel.

The second stage is the HEPA filter as the main filter for particulate pollutants. It removes 99% of the remaining smaller particles that passed the fabric pre-filter, including the tiniest pieces of dust, pollens, and smoke particles that are 0.3 microns and larger.

3.Coway AP-1512HH

The Coway AP-1512HH air purifier has a four-stage filtration system. It includes a pre-filter, activated carbon filter, True HEPA filter, and ionizer. The first stage is the fine mesh pre-filter, and it helps to remove larger pollutants such as mold spores, dust, pet hair, and pollen from the air. What you need to know is that the pre-filter is washable and permanent.

After the pre-filter, you have the deodorization filter. As the name suggests, the filter neutralizes odors and VOCs by chemical adsorption. This filter sheet is infused with activated carbon and helps to freshen your indoor air. However, this type of carbon filter is less effective than a pellet-based carbon filter. The carbon filter has a lifespan of 6 months.

4.Blueair Blue Pure

The Blue Pure 211+ air purifier is one of the most outstanding unit from Blueair, especially when it comes to handling the particulate contaminants in the air. The particle filter is a 46 square feet pleated filter made with Polypropylene, the same material used to make a HEPA filter.

The efficiency is 99% at 0.1-micron particle size, which is close to HEPA performance. This particle filter will be able to capture most of the airborne particulates like household dust, mold spores, airborne bacteria, and smoke par

5.LEVOIT Air Purifier

Levoit Core 300 air purifier is an excellent and compact air purifier that is easy to use and has good room coverage. The purifier is suitable for filter particulate allergens and light odors from small to medium-sized rooms. It is completely ozone-free and safe for kids and pets too.

If you are looking for a small room coverage air purifier with a high-efficiency particle filter, then you can choose either the black or the white variants of the Levoit Core 300.

Best Air Purifier for Office – BUYER’S GUIDE

Room Size Suitability

This is listed first for good reason — the capacity of your air purifier should be suitable for the room or space you are putting it in. Generally, smaller air purifiers are for smaller areas, and larger air purifiers are for larger areas. Makes sense right?

There is very little use in using a small air purifier for a big area because it just won’t have the ‘oompf’ to get the job done. Conversely, if you get an air purifier that is unnecessarily powerful, you’re probably spending more money than you need to.

For our purposes, we’ll list each air purifier by the following sizes:

  • Small — for small rooms or personals spaces under 300 square feet
  • Medium — for rooms or spaces between 300 and 699 square feet
  • Large — for rooms or spaces between 700 and 1,900 square feet
  • Whole House — for very large spaces or whole houses.

Air Exchanges Per Hour

This is a reasonably simple one, in that it measures how many times an air purifier will exchange (or clean) the air in the room per hour. The more times per hour the air is exchanged, the harder the air purifier works to keep the air clean.

Remember that this rating is only applicable to its room size suitability as above. If you put an air purifier designed for a small room into a large room, it’s ability to exchange the air per hour will be greatly reduced.

Filter Type and Capability

This one can get confusing, so we’ll try and keep it simple. The reason that it can be confusing is that there are many different types of filters, and sometimes manufacturers will try and have their own names for filtration to make it sound better than others.

In saying that, we will try our best to translate things for you — here are the main filter types to look out for:

  • HEPA (High-Efficiency Particulate Air) Filtration This is the one most people look for, as it’s tried and true. It uses a high-density paper filter to trap the dirt from the air. The specific term you’ll want to look out for is ‘True HEPA Filter’. If it says something like ‘HEPA Like’ or HEPA Type’, we’d generally suggest you stay away because it is just not as efficient as the real deal.
  • Carbon Filtration This air filter uses carbon panels that absorb fumes in the air. Note it just traps fumes; that is to say, it will not trap contaminants, only bad smells from the air in the room. For that reason, carbon filtration is usually used in addition to HEPA filtration.
  • Ionic Filtration This one is a bit more complicated, as it sends out charged ion particles into the room that then latch onto contaminants in the room. These contaminants then fall to the floor or other surfaces with gravity. Some of the more expensive ionic filtration devices will have a collection area that ‘suck in’ the contaminants from the air with electrostatic energy, so it reduces what falls on the ground or surfaces.

Then of course, more expensive options will have combinations of these filters or other filter technologies which we’ll explain as they arise.

Automatic Monitoring

This means that the air purifier will have sensors that can sense certain smells or contaminants, and automatically adjust to get rid of them as they arrive. Automatic monitoring is really handy for a set and forget arrangement.

Sound Level

All air purifiers will make a noise, usually a quietish humming sound. Generally, the more powerful the air purifier, the louder the sound, but more expensive models will have systems to keep them quiet. This may not be an issue for you at all, but it is for some. In our reviews, we’ll cover if they are exceptionally quiet, or louder than normal.

Energy Consumption

The best way to use an air purifier is to have it on all the time, and that can sometimes mean unpleasant surprises in your energy bill. Obviously the more energy an air purifier needs to run, the more expensive it will be to use.

Most air purifiers will have an eco mode, or be Energy Star certified to try and keep running costs down. In general, air purifiers are pretty energy efficient, costing not much more than $50 a year. But we will let you know whether any of our reviewed air purifiers will cost too much in energy!

Filter Change Indicator

It can be easy to forget exactly how long you have left your air purifier on, and therefore difficult to know when to change the filter. A filter change indicator is really handy for knowing when the filter needs replacing.

On Wheels/Moveable

The bigger an air purifier gets, the more cumbersome it might be to move from room to room. We’ve stated how easy each air purifier is to move.

Wi-Fi Capability

By no means a necessity, but you might find Wi-Fi capability handy to track the usage of your air purifier, or to see if it’s currently working, etc. This is also closely related to whether the air purifier has a mobile app, for which we’ll make clear.

Frequently Asked Questions

How Many Air Purifiers Do I Need for an Office?

The number of air purifiers you need depends on how many rooms your office has.

The general rule of thumb is to have one air purifier per room. That’s because air purifiers can’t work through walls.

If your office has a very large open area with lots of cubicles or desks, then you can quite possibly get away with buying just one air purifier.

As long as the air purifier you choose can cover the square footage size of the space, then it should be fine for that location.

However, if your office is divided up into individual rooms that have their own doors, then it’s best to put a separate air purifier in each of those areas.

Doing this will allow each person in your work environment to have their own personal bubble of clean, fresh air to breathe.

Where Should an Air Purifier Be Placed in the Office?

The best placement for an air purifier in an office is to get as close to the central point of the room as possible.

This will allow the air purifier to draw air in equally from the full volume of space.

You also want to give your air purifier enough clearance around the machine to function well.

The general rule of thumb is to allow 24 inches of clearance on all sides and the top of the machine.

But always check your owner’s manual for the exact measurements because it may recommend a larger or smaller radius for your particular air purifier.

Placing your air purifier in an optimal position is crucial for peak performance and is what makes air purifiers worth it.

Do Air Purifiers Remove Office Dust?

Yes, air purifiers do remove office dust if they contain a True HEPA filter.

A True HEPA filter is the only kind of air filter that can trap microscopic dust particles.

An Activated Carbon filter can trap some large dust particles but they’re not made for that type of work.

Air purifiers also get rid of dust mites and their waste which can help with with indoor allergies while you’re at work.

Will an Air Purifier Reduce Office Odors?

Yes, an air purifier will reduce office odors if it has an Activated Carbon filter.

An Activated Carbon filter is the only type of air filter that can reduce airborne odors.

Activated Carbon filters are made of a special type of material that adsorbs gases and chemical vapors.

Other types of filters like HEPA filters cannot trap airborne vapors, and therefore, those molecules just float right through them.

More details on this topic can be found here: do air purifiers remove smells.

Will an Air Purifier Kill Bacteria and Viruses?

Yes, an air purifier will kill bacteria and viruses if it has an Ultraviolet light.

An Ultraviolet light (or UV-C light) emits a beam of radiation that destroys the DNA structure of microbes and pathogens.

This radiation is completely safe for humans but kills bacteria and viruses.

If you want to have sterile air that’s less contaminated with particles that can make you sick, then a UV-C light is a must-have feature to look for on the best air purifier for your needs.

Do Air Purifiers Harm Office Plants?

No, air purifiers do not harm office plants.

In fact, air purifiers and plants can work well together to create the healthiest air possible in your workplace.

There’s nothing an air purifier does that can harm your plants and vice versa.

So feel free to add as many plants as you want to the office while running an air purifier in the same location.

We also have a page on the differences between air purifier vs plants if you want to understand how they compare for indoor air quality improvement.
