Benefits Of Air Purifiers

An air purifier is a small yet powerful piece of equipment that filters all the indoor air, making it breathable and pollutant-free. It can also help in:

·       Removing allergens from the air

·       Capturing pet dander, pollen, and dust

·       Removing mold spores, bacteria, and viruses, and preventing them from returning

·       Reducing odors, smoke, and chemical fumes

·       Revitalizing indoor environment by circulating clean air

8 Thing To Consider When Buying A Portable Air Purifier For Your Office

1. Your Needs 

Choose a portable air purifier based on the intensity of cleaning. Here are a few more things to keep in mind:

·       If your allergies act up because of the air quality, buy a unit that is known for the removal of allergens. It will have several filters, such as HEPA filters to ensure thorough cleaning of indoor air

·       If you suffer from respiratory issues such as asthma, select a chemical air purifier or asthma air purifier that’s known for the removal of particulates thanks to filters that can eliminate chemicals and odors from the air  

·       If your home or office has a dedicated smoking area or a fireplace, consider buying a smoke air purifier to eliminate the odor left behind from fumes and allergens that can exacerbate respiratory issues

·       If you bring your pets to work, choose a device that allows for the removal of pet odors, hair, and dander to keep everyone allergy-free

·       If your symptoms act up in the presence of chemicals, select an air purifier that features MCS, i.e., Multiple Chemical Sensitivities features to ensure that no chemicals are dispersed into the air during cleaning

2. Size Of The Air Purifier

To narrow down to the size of the air purifier you require, consider the following:

·       The square footage of the room that needs to be decontaminated

·       The particulates that augment your symptoms

·       ACH or air change per hour — the number of times the air will be purified within an hour

Ideally, an air purifier with 4 ACH is the best pick for enhancing air quality, and it removes microscopic allergens to ensure the breathability of indoor air.

Depending on how big or small your office is, choose between a small, medium, or large air purifier. Alternatively, you can pick a central purifier that covers the whole floor.

Square Footage Purifier Size
Close to 299 square feet Small
300 to 700 square feet Medium
700 to 1,900 square feet Large
1,900+ Extra-large

Remember, small air purifiers are meant for small spaces, so select a device that allows for easy portability, so that you can carry it along with you from room to room as and when required.

3. Features To Look For

Next, it is essential to ensure that the air purifier you pick comes complete with the following features:

·       Energy Star-rated air purifiers by EPA are known to conserve energy, which in turn lowers bills

·       WiFi-enabled air purifiers allow you to control settings right from your phone

·       Air purifiers with air-quality indicators offer precise assessment and real-time updates

·       Caster wheels

·       Handles to carry around

·       Multiple fan speeds

·       Remote control

·       Signs that show the condition of the filters

4. Maintenance

The air purifier only works well if it is clean on the inside; that’s why regular upkeep and maintenance are essential. Here’s what you need to know:

·       HEPA filters need to be replaced in a year. However, some filters can last for five years, so it’s best to refer to the manufacturer’s guidelines

·       Pre-filters can be washed for extended use, but typically they have a 3-month life span

·       AirFree air sterilizers do not depend on filters, so no replacement is required. They do the job by using UV lights and heat

5. Filter Replacement Costs

Depending on the size of the air purifier, its usage, and the number of filters it requires — replacement costs can range from $20 to $200 every 6-months to a year.

6. Endorsements

An excellent portable air purifier for your office should have the following certifications:

·       Energy Star-rated models – 40% more efficient than other units

·       AHAM seal – shows that the air purifier is tested and tried by the Association of Home Appliance Manufacturers

·       CADR or Clean Air Delivery Rate – refers to the amount of clean air produced by the air purifier on the highest settings. The higher the rating, the better:



240+ Excellent
180 to 240 Very Good
120 to 179 Good
60 to 119 Fair
Below 60 Poor

7. Noise

Air purifiers for your office space must have a quiet feature that lets them work in the background without producing excessive noise and disturbing the staff.

So, when testing, run the chosen air purifier at low as well as high settings and see how much sound is produced.

These noise levels are measured in decibels (dB), and the higher the dB, the more sound it will generate – you can find this information with the manufacturer easily.

For your reference, we would like to point out that refrigerators usually have a 50-decibel rating. 

8. Price And Warranty

You can buy some of the best portable air purifiers for your office for $50 and above – some of these models also feature HEPA filtration. High quality breathable indoor air doesn’t have to be outrageously expensive.

The best part is that most manufacturers provide ample coverage for their products so you can rest assured that your investment is secure.
