Here are our answers to the most frequently asked questions about air purifiers for offices, industrial air filtration systems and commercial air purifiers:
At MANN+HUMMEL we’re all about helping you keep your indoor environments virus free and people safe. Our filtration experts bring decades of scientific savvy to every product we develop, creating portable air filtration systems that work to remove harmful particulates from indoor air. The latest model in our range, the OurAir SQ 500, offers agile, mobile protection with all the benefits of our individually testedHEPA* H14 filters.
Research on the spread of Coronavirus is fast-moving and extensive. We know that small airborne particles can linger in indoor air for a considerable time and reach further than the 2m social distancing guideline. If these particles carry the SARS-CoV-2 virus you and others in the room are at risk of infection. Polluted air can also cause respiratory conditions and chronic disease. An effective H14 HEPA* filter air purifier helps remove harmful pathogens from your workplace. Which means you and your customers and colleagues can stay safe.
Here’s how the OurAir SQ 500 keeps your air virus-free:
Fitted with a HEPA* H14 filter our mobile smart air purifierremoves up to 99.995% of viruses, bacteria and other micro-organisms from indoor air in rooms up to 40m2. The H14 HEPA* (High Efficiency Particulate Air) filter captures microscopic particles up to 0.3μm in size, so that as air is forced through the unit’s filter even the tiniest micro-organisms are trapped and taken out of circulation.
Our portable HEPA* filter unit achieves air quality equal to many cleanrooms and surgical theaters. The OurAir SQ 500 features a new multi-layered ePTFE membrane that offers high filtration levels at very low resistance, making it energy-efficient and quiet.
Don’t just take our word for it – our commercial air cleaners have been proven to be successful in ensuring people can breathe clean, healthier air. So, if you’re concerned about protecting your co-workers and customers, installing an OurAir SQ 500mobile air purifier alongside your other health protection measures will give you that much-needed peace of mind.

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.

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:
- OurAir SQ 2500 for rooms up to 200m2
- OurAir SQ 1750 for rooms up to 140m2
- OurAir SQ 500 for rooms up to 40m2
*according to ISO 29463 and EN 1822
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. 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.
*according to ISO 29463 and EN 1822
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.
