* Please note our Clean Air Delivery Rate (CADR) is calculated at the lowest fan speed as despite our unit being quiet this is the setting the unit is most likely to be used at when room occupied. Most competitors calculate their CADR at the highest fan setting which is unrealistic in a workplace setting.

Air sterilisation maintenance FAQs

Maintaining your air steriliser
Our air sterilisation units are built to last, but maintaining your air steriliser is important. That’s why each machine comes with a five-year guarantee and free first year full maintenance service.

Can I change my own filters and UVC lamps?

The replacement of filters and UV-C lamps should be carried out by a professional. They understand health and safety regulations, and will undertake a risk assessment to make sure the work is carried out safely.

How often should I maintain my machine?

Air sterilization or purification units require annual maintenance. This includes changing filters and UV-C lamps.

How do I clean a HEPA filter?

We don’t recommend washing or vacuuming HEPA filters. Trying to DIY clean your HEPA filter will drastically reduce its performance. Instead, we recommend you liaise with our engineers to replace your HEPA filter at least annually.

How often should I change a HEPA filter?

We recommend all HEPA filters are replaced at least once a year. This could be more frequent, depending on the operating hours and level of pollutants.

How often should I change UV-C lamps?

The UV lamp used to disinfect your office air should be replaced at least once every year, or after 8,000 hours of use.

How often should I change carbon filters?

Activated carbon filters should be replaced annually for maximum effectiveness.

How can I tell if my filters or UV-C lamps need changing?

If you notice the effectiveness of your machine reducing, via the indicators, you may need to consider replacing your filters or UV-C lamps. Contact So Pure Air’s team of trained engineers for further advice.

Will replacing filters and UV-C lamps release contaminants?

Viruses are unlikely to survive very long on a HEPA-like surface. However, we always recommend handling HEPA filters and UV-C lamps with care. Our trained engineers are best placed to help maintain your machine.

How do I know what technology my machine uses?

So Pure Air machines are designed for commercial use. Our machines use medical grade filtration technology. HEPA filters, for example, are scientifically recognised to reduce the spread of viruses and bacteria.
