How to Buy the Best Office Air Purifiers

How to Buy the Best Air Purifiers for Office

Photo: sylvane.com

1. Coverage Area

This is one of the most important considerations to make when choosing an air purifier for the office. Ultimately, the purifier you get needs to clean the intended space efficiently.

Typically, the area is represented in square feet (sq. ft.), and most air purifier models will be rated for different coverage areas.

If you have a large office space of 1000 feet and over, consider getting Bissell air320 2768A or Levoit LV-H134, both of which offer superior coverage.

2. Filter Technology

Besides coverage, your office air purifier’s efficiency will depend largely on the filter technology it uses, which is closely tied to filter quality.

The most efficient air purifiers use industry-leading High-efficiency particulate air (HEPA) filters, which are rated for removal of at least 99.97% of contaminant particles including dust, pollen, mold, bacteria, and many more, from the air passing through them.

All the models in our list come fitted with HEPA filters, but their life may vary depending on usage and capacity.

3. Speed Settings

Air purifiers provide operational flexibility through their multiple speed settings. Most models offer at least 3 fan speed levels, while some go up to 5.

The idea behind speed settings is that when the purification demands are low, you can select slower fan speeds, typically 1 and 2, which also reduce power consumption and noise output.

But sometimes, high fan speeds may be needed when the air is highly contaminated by particles such as dust, or even smoke and odor. In such cases, robust options such as the 5 in Bissell air320 2768A will come in handy.

4. Extra Features

Any extra features that seek to boost an appliance’s productivity are always welcome. One of the handiest extra features offered by air purifiers is a remote control, especially for office use.

With a remote control, you can operate the purifier conveniently, at any spot within the room, sometimes without ever having to move. The Oransi OV200 comes offers a remote-control feature.

Wi-Fi connectivity is another convenient feature that also enables remote purifier control through a smartphone app. The RabbitAir SPA-780N and Blueair Classic 480i both support Wi-Fi connectivity.

5. Energy Consumption

The amount of power your air purifier consumes will have an impact on energy costs, especially in the long term. That’s why when choosing a purifier for the office, it’s important to consider the model’s power-efficiency.

You’ll be pleased to know that our top purifier peaks are very economical in their energy consumption. Most of them draw less than 100 watts even at peak power. And when running at slow fan speeds, they consume even less power, often up to 50 watts, or slightly more.

6. Sound Level

The general rule for most of the appliances we have at home and in offices is that the quieter they run, the better. And the air purifier is no exception to this rule.

Typically, your air purifiers noise production reduces with as fan speed lowers. The noise produced at fan speeds 1 and 2 is significantly lower that of levels 3, 4, or even 5.

Low noise outputs of less than 25 dB, such as those of Levoit Vital 100 and Alen BreatheSmart 45i ensure the least disturbance from your air purifier as it runs in the office.

7. Portable

The portability of your air purifier depends largely on its weight and size. Heavy models air typically harder to move around, especially in the office.

While the idea is to go lightweight when seeking to boost portability, this gain may come at the cost of performance as the heavier units tend to pack more power.

Compact purifiers, such as Oransi OVHT9908, work well in tight spaces, and will even sit on an office desktop for efficient space utilization.

Conclusion

It’s no doubt that air purifiers stand to add a lot of value to your office space by boosting air quality.

If you want the best of them all, choose Winix 5500-2, an inexpensive, efficient, and compact air purification unit that is also easy to use and ideal for small-to-medium rooms.

If you’re on a tight budget but still desire a quality air purifier, pick the more affordable Levoit Vital 100, which is ideal for small spaces.

And for a large office space that demands a high-performance purifier, Bissell air320 2768A is a wise choice.
