Office air purifier in the test comparison 2022: equipment and costs

The most important facts about air purifiers for offices and businesses

The following summary shows which three factors are particularly important when selecting a suitable air cleaner model for workspaces.

Room structure and size: In rooms with lots of corners, it can make sense to use several small devices instead of just one large device. Because air purifiers only suck in the room air that is in their directly accessible environment. If a cupboard, a partition or a large plant is in the way, this significantly reduces their performance.

Cleaning performance (CADR): How efficiently an air purifier works can be seen from its CADR value, which is given in cubic meters per hour. Important: In order to fight corona viruses, the devices must clean the entire room air several times per hour and also have a class 13 HEPA filter. Even away from the pandemic, air purifiers ensure good air, which can increase concentration.

Costs: In addition to the purchase price, the power consumption and the costs for replacement filters should also be considered when making your selection. Because high power consumption shows up on the electricity bill. Depending on the device, filters usually have to be replaced two to four times a year and result in follow-up costs.

The following five models convinced us with their price-performance ratio.

Purchasing advice: Air purifiers for offices and businesses

In the following overview, we explain which factors interested parties should know before buying an air purifier for their business or office:

Room size / room structure: A good air purifier draws the entire room air through an H13 or H14 filter several times an hour in order to be able to efficiently capture corona viruses. In offices with partition walls, large plants or similar obstacles, it also makes sense to set up several small devices instead of just one large one, so that stale air cannot collect in corners or gaps.

Cleaning performance: It largely depends on three factors: Firstly, the air circulation per hour, secondly, the filter quality and thirdly the placement of the device.

Volume: It is usually much louder in a workshop or a call center than in a single office. How loud the noises of the air purifier are perceived at all or perceived as disturbing also depends on the ambient noise level. Tip: Most devices offer a so-called sleep mode for particularly quiet operation.

Operation: The control of functions via device buttons is standard on almost all air cleaner models. More and more are also offering the option of using a classic remote control, smartphone app or voice assistant for even more convenience.

Care and maintenance: In order to achieve consistently good cleaning results, the filter must be replaced regularly.

Price: Inexpensive air purifiers for the home office are available from around 100 euros. Professional solutions for large commercial spaces such as industrial production halls, restaurants or schools, on the other hand, quickly cost several thousand euros.

Follow-up costs: After the purchase, there are permanent electricity charges and costs for replacement filters. This should be taken into account when purchasing.

Test overview and evaluation of air purifiers for offices and businesses

What are the best air purifiers for the office?

In our air purifier for the office test comparison, we recommend the following devices:

Do air purifiers with water make sense in the office?

Air purifiers are a good addition to regular airing in the office. Although they remove many pollutants, they cannot enrich the room air with fresh oxygen. For this reason, good ventilation should be ensured regularly even when using an air purifier.

Also important: Viruses, bacteria or dust particles that sink from the air and e.g. B. deposits on cupboards or desks are no longer detected by the air purifier.

Do air purifiers with water make sense in the office?

Also important: Viruses, bacteria or dust particles that sink from the air and e.g. B. deposits on cupboards or desks are no longer detected by the air purifier.

Which pollutants can be removed in the office with an air purifier?

Even seemingly clean office or commercial spaces often contain microscopically small pollutant particles. These include the following:

Toner dust: Even modern printers and copiers can release toner dust and irritate the respiratory tract or exacerbate existing asthma conditions. Tobacco smoke: Anyone who lights a cigarette indoors despite the smoking ban distributes, among other things, Pollutants such as benzene, tar or formaldehyde.Volatile organic compounds (VOC): They arise e.g. B. through the use of cleaning agents or escape from plastic furniture or paintwork. The two pollutants formaldehyde and the plasticizer diethylhexylphthalate (DEHP), which frequently escape from PVC products, are particularly common in offices. Allergens: House dust, pollen, bacteria and viruses get into the office through open windows or on people’s clothing. Office dogs can also collect pet hair.

Are there Corona air purifiers especially for the office?

Various specialist companies, such as TROTEC Industrie, offer air purifiers for large areas on the market. These extremely powerful devices can even keep a fully occupied classroom or open-plan office free from pollutants and corona viruses. However, they are often very expensive and must be installed by experts.

We therefore recommend combining several of the mobile devices presented here for smaller office communities, in order to achieve good room coverage with less cost and effort.

How long does it take to install air purifiers in an open plan office?

All of the air purifiers we recommend for home office users or small offices and practices can be installed by the user themselves in just a few minutes. On the other hand, if you buy a large industrial device for several thousand euros, e.g. B. to make an open-plan office more hygienic, it is better to use the manufacturer's installation service.

However, since such professional devices can reach a height of up to two meters or more, installation and configuration may take several days.

How often is a filter change necessary?

Depending on the model, the filter usually has to be replaced every three to six months. Shaking out or vacuuming for reuse is not recommended, because it is not possible to adequately clean the filter fins that are clogged with dirt particles.

How loud are air purifiers in the office?

Concentrated work can be massively disrupted by the loud whirring or humming of office equipment such as fans, heaters or air purifiers. Fortunately, however, most devices offer a night or sleep mode with particularly quiet operation.

How quiet your own favorite actually is in practice can be estimated using our comparison table:

10 decibels: Breath sounds or snowfall 20 decibels: Forest noise 30 decibels: Watch ticking 40 decibels: Whisper, soft music 55 decibels: Rain, refrigerator 65 decibels: Normal conversation, TV at low volume 70 decibels: Vacuum cleaner

Are the federal states promoting office retrofitting with air purifiers?

Most federal states promote CO2 sensor air purifiers, especially for schools. In Bavaria, child day care facilities, large day care centers and curative day care centers also receive grants, provided these are applied for at the State Ministry for Family, Labor and Social Affairs.

Until March 31, 2022, small and medium-sized companies and the self-employed can also apply for financial support using the online form Bridging Aid III Plus, provided that there was a 30 percent drop in sales in the funding period from July to December 2021. The conditions correspond to Bridging Aid III, which subsidizes conversion costs for hygiene measures such as air cleaners, among other things.

However, some other federal and state funding measures were only available until December 31, 2021 and it is not yet clear when and to what extent they will be continued. (Status: 01/2022)

Tip: If you are a member of BG Bau, you can still apply for money for new air filters using the online form as an occupational health and safety bonus. (Status: 01/2022)
