Do portable air purifiers work?

The answer is a categorical yes! Research has shown that air purifiers are effective at removing bacteria, micro-organisms and viruses from indoor air. But that doesn’t mean every portable air purifier is created equal. For the most reliable, efficient filtration look for units that are fitted with HEPA* H14 filters. These offer maximum protection from harmful pathogens and airborne droplets.

When purchasing a mobile HEPA* H14 filter unit, price is not the main consideration. Research performance data and the air flow exchange rate, energy consumption and portability to ensure efficient, long-lasting filtration. Lowest possible noise outputs should be one of your key decision drivers as well.

Are portable air purifiers effective?

In addition to the filter specifications, another factor affecting how well a mobile HEPA* filter unit works is where it’s placed within a space. Move the unit around regularly if using in multiple rooms to ensure effective filtration across your building or office space. Used properly, your mobile H14 HEPA* air purifier will provide clean air throughout this pandemic and way beyond.

To get the best air purifier for your office space or workplace you must also check that the unit is suited to the size of your room or indoor space. Our room air purifiers are suitable for the following room sizes:

How does a portable air purifier work?

Mobile air purifiers work in the same way as stationary units. They contain a fan which forces air through a fine-meshed filter with varying sized gaps. Air purifiers with HEPA* filters of H14 specification can catch particles as small as 0.3μm. Here is the difference between H13 and H14 HEPA* filters: H13 filters capture 99.95% and H14 filters trap 99.995% of viruses, bacteria and micro-organisms. The filter captures airborne particulate matter and prevents it recirculating as clean air is fanned back out into the room.

Many mobile air purifiers run quietly, though it’s virtually impossible to find a completely silent air purifier due to the fan motor that needs to run constantly.

Where to place an air purifier in an office? 

For optimum functionality mobile HEPA filter unit should be positioned near the source of most pollutants or in an area of high airflow. Unless the unit has 3600 filtration it’s better not to place it in the corner of a room. If your professional air purifier has a low-positioned filter it may need to be raised off the ground to ensure maximum air flow. If you need help choosing the right air purifier or figuring out the ideal position for it within your indoor space, do get in touch and we’ll be happy to help.
