The 360-degree progressive filtration system used in the Healthmate purifier helps remove the most symptom-aggravating chemicals, odors, and allergens from your home. By running it regularly, you can experience a reduction in your asthma, allergies, and MCS symptoms.

This purifier pulls in air from all sides, which then passes through the 4-stage filtration process. It cleans the air faster and more efficiently than most conventional air purifiers.

The medium particle filter, in the second stage, removes medium- to small-sized allergens. The air then passes through a 15-pound activated carbon filter infused with potassium iodide and natural zeolite. This helps to trap odors, fumes, gases, chemicals, and VOCs.

Lastly, the air moves through 60 square feet of the medical-grade HEPA filter, which cleans the air of harmful bacteria, mold, viruses, pollen, dust, pet dander, and ragweed particles.

The Healthmate Plus is constructed with durable, sturdy components that boost energy savings and efficiency. The long-life PSC motor, all-steel outer body, and a powerful centrifugal fan all ensure that this unit serves you for a long time.   

The Healthmate Plus is easy to use. A simple knob control makes it easy to choose from 3 purification speeds. The smooth-rolling casters ensure easy portability, and to remove the filter, you just need to remove the bottom cover, take out the old filter, and drop in a new one.

However, you need to replace the combination HEPA/carbon filter once every 5 years, helping you save money on expensive filter replacements.

Office Air Purifiers: Buying Guide

Why Buy an Air Purifier for an Office?

air purifier for office

According to research, a clean environment at your workplace is good for your health and boosts your productivity. However, your air purifier should include a True HEPA filter, UV light, and Activated Carbon filter to ensure its excellent performance.

Researchers are also of the opinion that better air quality in the office can help improve cognitive performance among your employees. So, with a good-quality air purifier, you can not only improve the physical health of your employees but their mental health as well.

Features to Consider

It is vital to consider a few things before making a purchase to ensure that you get the best model for your office. Not all purifiers are constructed the same, and investing in the wrong type may not get you the desired results.

To help you get a unit that can meet the demands of office space, it is best to keep the following tips in mind:

Filter Type

Many pollutants can be present in your office air, which is why we recommend units designed with mechanical filtration as their filters can physically capture the pollutants that pass through them. 

Such units typically have at least two filters - a pre-filter that traps large particles such as pet hair and the main filter that catches smaller pollutants. Pre-filters do not usually differ in quality.

Some are disposable, while others are washable. The former may increase the unit’s operational cost in the long run; however, there is not much to compare.

The main filter of your air purifier is another matter. You want to look for an air purifier that utilizes a high-efficiency particulate air (HEPA) filter, which is recommended by the EPA.

HEPA filters are capable of trapping 99.97% of particles that are even 0.3 microns in size. You may also find units with HEPA-type filters, but they are not rated to meet the filtration level that HEPA filters provide.

Some air purifiers are equipped with additional filters like charcoal or activated carbon that trap odor compounds, gases, and volatile organic compounds (VOCs).

These extra filters are particularly helpful if you are allowed to smoke in your office. However, you need to change them regularly to be effective.

Some air purifier units also feature filtration processes that depend on ultraviolet light (UV) or ionizers. These units, however, may produce ozone, which can aggravate breathing-related problems.

Cost of Operation

Most air purifiers are designed with filters that need to be replaced frequently. Activated carbon filters need to be replaced every 3 months, while pleated filters should be replaced every 6 to 12 months. 

The cost of these filters varies widely, so make sure that you keep this additional cost in mind when looking for a suitable unit.

Coverage Area

Different air purifiers are designed to cover a particular amount of space. Some are better suited for small cubicles, while others can efficiently cover large open office spaces.

Find out the size of your office and make sure that the unit you choose can handle your required space. The best unit for your office is one that meets or exceeds the square footage (length x width) of your office. 


People need air purification in different areas of their offices, which is why compact and lightweight options are best. Bulky and big exteriors can make it difficult to move the units from one room to another.

Technology Type

Some air purifiers are designed with the innovative Photo Electrochemical Oxidation (PECO) technology. Such units use free radicals to break down pollutants like mold, allergens, VOCs, bacteria, and viruses at a molecular level.

With the help of nanotechnology, PECO destroys pollutants almost 1000 times smaller than the ones that traditional filters ordinarily remove.

When used in a workplace or office environment, air purifiers designed with PECO technology can keep the air extremely sterile and clean without letting any particles slip through.

These air purifiers are also great for asthmatics as total particle elimination helps improve lung and respiratory functions.

Noise Levels

You just do not have to keep in mind how well a purifier performs but also determine how well you will be able to live with it. Since you’ll be running your purifier continuously, so ideally, it should be quiet.

You can find out the decibels of a particular model on its packaging or website before making a decision.


Choosing the correct air purifier size for your office ensures its efficiency and effectiveness. Most manufacturers recommend a suitable room size for their models.

Some can be placed on your desk, while others need to be placed on the floor. Make sure that your chosen model corresponds to the area you want to purify.


Choosing an air purifier for your office that comes with a warranty or a trial period helps promote greater peace of mind.

Filter Types for Office Air Purifiers

With many people going and coming and so many different office pieces of equipment running, your office air could contain high levels of contaminants.

To keep your office air clean and fresh, it is vital to get an air purifier designed with at least 2 filters - the True HEPA filter and the activated carbon filter. Some units are also fitted with ultraviolet light for increased protection.

True HEPA filter

A True HEPA filter is essential in an office as it is the only filter that can capture 99.97% of particles down to 0.3 microns, including allergens, bacteria, mold spores, PM2.5 (from factory and automobile exhaust smoke), and dust, etc. 

However, when searching for an air purifier, you might find units that use words like ‘HEPA-type,’ ‘HEPA,’ or ‘HEPA-like’ with their names instead of the word ‘True.’ It is best to stay from such units as they are less efficient than a True HEPA filter.

Only True HEPA filters are guaranteed to capture ultrafine pollutants that can be harmful to your health.

Activated Carbon Filter 

An activated carbon filter is essential in an office purifier as it traps particles that escape a True HEPA filter. There are a number of contributing factors to VOCs or Volatile Organic compounds in a workplace.

VOCs are invisible chemical vapors and gases discharged by both building materials that make up the office like paint, drywall, and carpeting, and office equipment such as fax machines and printers, etc.

In addition, chemical cleaning agents emit VOCs, and it can take hours or even days for the particles to dissipate.

Exposure to VOCs can cause headaches, nausea, loss of coordination, and eye, nose, and throat irritation. As a result, there can be severe damage to the kidney, liver, and central nervous system.    

A True HEPA filter is not designed to capture VOCs; however, an activated carbon can. These filters are constructed with a unique substance that eliminates VOCs. Plus, activated carbon filters help reduce odors in the workplace.  

Ultraviolet Light

Another filter that can increase the efficiency of your office air purifier is ultraviolet light. The UV-C light is a bulb fitted inside an air purifier, and it emits a low level of radiation. When the air passes by the UV-C light, it disrupts the DNA of the viruses and bacteria and kills them.

Most air purifiers available are not equipped with ultraviolet light; however, using one for your office can make the environment more sterile.

Office environments are notorious for spreading germs, particularly during the flu season. An air purifier with a UV-C light helps reduce the pathogens and microbes floating around the room.   

Pros and Cons of Using an Air Purifier in the Office

An office air purifier helps breathe easier when used indoors. From increased productivity to odor removal, these units can improve air quality in a number of commercial settings, from warehouses and factories to wellness centers and nail salons.

However, they have some limitations, too.


  • Odor elimination: You cannot see smell; however, they can create an undesirable vibe in a commercial setting. Chemicals, smoke, and musty air are some examples of odors that can make your work experience an unpleasant one.  
  • Removing bacteria: True HEPA air purifiers not only remove airborne particles from the air but also cut down on the dissemination of bacteria.
  • Allergy relief: Many people are affected by allergies. According to experts, allergies are also one of the main causes of chronic illness. An office air purifier can capture and filter particles that can trigger allergies.
  • Mold and mildew prevention: Some common causes of mold and mildew are airflow problems, potential humidity, and moisture. Using an office air purifier can help prevent the development of mold and mildew and create a healthy workplace.
  • Prevents cold and flu: An office purifier can also help prevent the spread of cold and flu by preventing the spread of airborne particles that can carry illnesses.
  • Increased productivity: Fewer health problems among your employees mean fewer sick days and increased productivity. Clean indoor air helps make customers, patients, vendors, and workers feel more energized and healthy. As a result, you will see a positive attitude in your team, which, in turn, will mean better business.


  • Increased costs: Using an office air purifier can increase overhead costs. There might be an increase in energy expenses in addition to the cost of replacing the filters.

Frequently Asked Questions

Are office air purifiers able to kill bacteria and viruses?

Many air purifiers can trap and even kill bacteria and viruses, but only those present in the air at the time. A HEPA filter is highly effective in trapping 99.97% of particles down to 0.3 microns.

It is also important to note that air purifiers are not a substitute for good hygiene, like cleaning hard surfaces and regularly washing your hands.

Is running an air purifier harmful for your office plants?

Some scientists believe that choosing the right air purifier for your office does not only help to detoxify the air but also helps plants grow.

Air pollutants in the air can hinder the food-making process of plants. Air purifiers help by removing the pollutants in the air, making it easier for plants to carry out photosynthesis. 

On the other hand, ozone generators and purifiers that release ozone are not advantageous for plant growth. The ozone released by these air purifiers adversely affects all living things, including plants.  

Can an air purifier effectively reduce office odors?

Air purifiers equipped with activated carbon filters can effectively remove odors, gases, and chemical toxins from the air.

When the carbon in these filters, which is basically charcoal, is treated with oxygen, many tiny pores form between the carbon atoms. This enables the activated carbon to adsorb odorous substances from liquids or gases.  

In addition to using an air purifier, it is better to address the problem by removing the source of the unpleasant smell as much as possible.

Can air purifiers effectively remove office dust?

Air purifiers designed with HEPA filters can effectively remove 99.97% of airborne particles, which helps to control and reduce dust in your office. When used 24/7, these units can also reduce the need to dust the furniture regularly.

What is the best place in an office to set an air purifier?

The best place for an air purifier in your office is the spot where the airflow reaches all corners of the room. Make sure you place your air purifier on a stable surface that is at least 30 cm away from the wall and 100cm away from the ceiling. It is also best not to place air purifiers in corners.  

Final Verdict: What is the best office air purifier sold today?

After carefully reviewing some of the best office air purifiers available today, we believe that the Healthmate Plus is the best unit available.

It can eliminate more than 3,000 types of odors and toxic gases, 95% of particles that are 0.1 microns in size, and 99.97% of airborne particles that measure 0.3 microns or larger.

So, with this unit, you can rest assured that the air in your office is fresh, clean, and free from odors.
