Why Office Air Purifiers are Different?

When we are selecting an air purifier for your bedroom, we do not care much about the number of specifications in label, capacity, and requirements as wide as commercial purposes.

But when we talk about official purposes, things are quite different. There are some factors that directly impact the office indoor air quality, unlike the home bedroom.

1. Number of Co-workers

Most of the office areas are filled often with a number of office colleagues from time to time depending on the time of the day.

So air pollution inside has a higher chance of risk to get increased or changed on their update of movements.

When a few of the office workers got sick or have air germ carriers entire office area can be easily gathered with air pollutants, unlike in homes.

A higher level of co-workers increases air contaminants – Air Purifiers for offices

Most of the people in office areas represent different locations of the surrounding and different travel mediums with vast kinds of air contaminants there is a higher risk of the office atmosphere getting contaminated depending on the office workers.

Another noticeable fact is when the number of office workers got increased, the percentage of clean air portion breathed by each individual get decreased. Practically this causes several spread illnesses at higher significant levels.

2. Location of Office

Most of the office areas are located near urban locations unlike, households. Due to this reason, it is normal fact that office areas are filled with several air pollutants like;

  1. Ozone
  2. Particulate matter (PM10, PM2.5)
  3. Sulfur oxides
  4. Nitrogen oxides
  5. Carbon monoxide
  6. Volatile Organic Compounds

Therefore, most of the office areas are fully covered to the outside and updated with HAVC systems from time to time.

3. Photocopier machines

Most of the office areas are filled with computers, scanner machines, fax machines, Xerox machines, etc. But with the development of the technology, the latest design photocopier machines in the offices are coming with combination altogether.

Office Photocopier machines make things worse

Most of the photocopier machines in office rooms are placed in the center of the office for easy access. Apart from their usage air purifiers releases several air pollutants like:

  1. Toner particles
  2. Ozone
  3. Nitrogen dioxide
  4. VOCs

Besides that, air copier machines are a good source of harmful radiation and some low electromagnetic fields.

Besides these machines being placed in a separate protective location, most of them are harmful to day-to-day exposure.

4. Poor indoor ventilation

According to the united states Occupational Safety and Health Administration(OSHA), having a proper air quality index (AQI) inside the office area is a right of office workers and is coming under government regulation.

A few decades ago, which environment was not a fundamental need and most employers disregard it due to the higher level of bills for maintenance and it does not proper income generation.

But indirectly losing a large number of dollars to the company was recorded by decreasing the health condition of coworkers. Most of the time, diseases like:

  1. Headaches,
  2. Fatigue,
  3. Trouble concentrating,
  4. Irritation of the eyes, nose, throat, lungs, etc.

Therefore, administration in the companies always worries about the maintenance of the indoor airways, filters, air purifiers, and HAVC systems from time to time to increase the efficiency of the workers although there are not properly mentioned guidelines for air office area air quality.

Other than these, there are several reasons behind indoor air pollution in office areas.

  1. Furnishing
  2. Pesticide applications
  3. Indoor cleaners
  4. restroom air fresheners
  5. asbestos from insulating and 6. fire-retardant building supplies
  6. formaldehyde from pressed wood products
  7. Other indoor materials

Before Selecting Air Purifier for Offices

Unlike household air purifiers, commercial air purifiers need to have higher performance and longer operational tasks.

1. Noise

The noise level of air purifiers does not significantly impact office workers as well as the bedrooms. Most quiet air purifiers have below 40 dB operational noise and that kind of air purifier is not required for office rooms.

But the practical situation is, that proper OSHA guidelines need to be fulfilled through the selected air purifiers eventually.

2. Coverage

Most of the office rooms are large in size and filled with a number of office workers. Therefore, a higher level of room capacity needs to be cleaned more than 10 hours per day. Before selecting an air purifier for an office area, having a proper idea about its measurements is the main requirement.

CADR value is a good measurement of this. CADR stands for Clean Air Delivery Rate.

It is a direct measurement of an air purifier’s efficacy. CADR ratings measure the volume of air in CFM (cubic feet per minute) for given air pollutants. CADR value is proportional to the size of a room.

3. Operational time

Unlike house rooms, office areas are preferring air purifiers with lower operational capacity. Mostly around 10 – 12 hours per day.

But the practical issue is unlike normal domestic air purifiers these are commonly open to higher levels of air pollutants and a larger area of the atmosphere.

Although with a lower level of operational hours, filters need to be replaced from time to time quickly.

4. Filters

HEPA air filters are the best options for office air purifiers unless there is any higher medical requirement. Medical grade air purifiers are also quite good for offices, depending on the office community.

During the pandemic season of coronavirus, people tend to use medical-grade HEPA air filters, but practically they are not 100 % sure about virus filtration.

On the other hand, air HEPA filters have quite small pores compared with others filters. So there is a higher chance to clog them from time to time, higher than the manufactures specifications.
