Buying Guide for selecting Best Air Purifier for Office

Buying an air purifier for the office is a hard nut to crack, especially when you have so many options around you. But we have made your shopping effortless by providing a list of factors which you should keep in mind while investing in an air purifier.

The factors mentioned here are of great importance because these will decide the fate of the purifier’s output. These will help you channelize your requirement and think accordingly.

Here are a few of the most vital factors discussed in deep detail for your guidance and help.

Before you buy an air purifier you should be well aware that there are types of pollutants in which everyone needs to be treated differently. So for such difference, the manufacturers have incorporated layers of filters that work categorically on its dedicated particle and pass the air on to the next one to treat it.

The office has so many people to deal with, everyone brings new kind of dirt or airborne particle which needs to be treated. So it is necessary that one keep a serious focus on which filters or combination of filters is better for the office.

Every air purifier should contain at least the two filters, to offer what is needed:

  • True HEPA filter.
  • Activated Carbon Filter.

Other than these two, advance and modern purifier also have:

  • UV light.

These three together do wonders.

What is a True HEPA Filter?

Briefly describing, it is a unidirectional filter that allows airflow in a positive direction within the room. It claims to eliminate 99.9% of germs and can eliminate 0.3 microns particles from the air. Office mostly contains dust pollution, molds, lint’s, PM2.5 which are released form cars and other automobiles.

Never buy any air purifier that does not use the word true with its HEPA filters, as these are not as effective as a true HEPA filters and are basically a modification of HEPA filters that does not clean air with great efficiency.

Activate carbon filter

These filters are of great importance when it comes to the office. True HEPA filters capture the physical form of dust and lint from the air whereas activated carbon filter captures gas in the air that is hazardous to the lungs otherwise. VOC is a type of gas mostly found in office vicinity; it emits form devices links computers, laptops, and chemicals to clean office, etc.

VOCs can be life-threatening if not treated in time. These can cause low energy levels and reduce the efficiency of staff working in the office. At the most dangerous levels, it can cause the death of a person if he/she inhales a dangerous quantity of VOC.

Activated charcoal has the ability to entrap gas, thus after true HEPA is done with their work then comes the activated charcoal which further cleans the air and makes sure the workers are safe.

You should always make sure the purifier mentions activated charcoal; otherwise, it is of no use. This filter is a lifesaver on which no compromise can be done.

Apart from VOC, activated charcoal can also remove odor from the air, as the odor is gas molecules form any material. Thus making the working area clean and comfortable o use.

Ultra Violet light

It is one of the best additions to the filters. You must consider it if you want high-end air purification. It works with a simple phenomenon but offers a great deal of protection to the users. If you will add this filter in your list then this is obvious that the price range will increase, but sometimes spending money on your and others’ health is a better option. It works to kill germs which otherwise can make your office staff unwell and the chances of absentees can be increased.

UV light works with a simple phenomenon; it is placed as the last layer of the filter. When air passes under the UV chamber it disturbs the DNA of bacterial strain resulting in its death. Thus the air that the purifier will release will be free from any infectious bacteria.

So it is highly recommended that you buy an air purifier having UV rays in it.

PECO Technology

It is another important technology that you will find in the air purifier, while I recommend to prefer it. This works by producing free radicals that kill the virus, bacteria and release open fresh air that s healthy to breathe.

Most of the air purifier lack PECO technology as it adds cost to the machine, but I recommend you to categorically buy a purifier with PECO technology if your office is in an area where if bore diseases are common.


Whenever you buy any product, its weight should be your prime focus epically if you intend to move that product repeatedly. Most of the large scale if the cleaner is heavy, but you should focus on buying one which is light and portable so that you can take it anywhere In your office.


This is another important feature, as we know, manual devices are laborious where automatic is easy to use, especially in the office where every individual is busy in tasks. So try to buy an air purifier which is automatic.


In this hustle and bustle and busy working routine, self-care and health are taken for granted, but if you want a healthy working environment, than an air purifier is a must for your office vicinity.

All the cleaner mentioned in the list above is efficient, smart, and up to date.

  1. Oransi Max HEPA Air Purifier advance and affordable.
  2. BISSELL air320 Smart Air Purifier with HEPA and Carbon Filters easy to use, fine filters with UV light.
