Frequently Asked Questions

What is the SA700?

The SA700 is a high-performance air purifier designed for schools, clinics, offices, and other shared spaces. It delivers up to 498 m³/h of clean air while using just 10 watts of power with the HEPA H14 filter and unpo 720 m³/h of clean air while using 12 watts of power on HEPA E11, combining strong filtration performance with exceptionally low running costs. In the UK, the SA700 comes standard with an H14 HEPA filter. In some other countries, the product may be sold with an E11 filter as standard. If higher CADR and airflow are preferred, you can choose to buy the E11 replacement filters separately.

How much electricity does the SA700 use?

The SA700 uses only 10 W, even at full performance. Running it continuously 24/7 for a full year uses approximately 88 kWh per year, costing approximately £25–27 annually. That is similar to the power usage of a Wi‑Fi router or a small LED light running all year. Based on typical UK electricity prices, running the SA700 continuously at 10 W would cost around £25 to £27 per year, or roughly £2.10 to £2.25 per month.

Why is the SA700 more energy efficient than most air purifiers?

The SA700 uses a carefully engineered 9-fan airflow system that maximises airflow while minimising energy consumption. Most conventional air purifiers use 40 to 80 W or more, while the SA700 achieves high clean air delivery at just 10 W.

Does the SA700 use a true HEPA filter?

Yes. The SA700 is available with H14 HEPA filter at the moment but we will also stock E11 replacement filters in the next couple of months. The H14 version is certified to EN1822 standards. H14 is the highest classification of HEPA filter — the same grade used in hospitals, operating theatres, and pharmaceutical cleanrooms. It captures at least 99.995% of airborne particles down to 0.1–0.3 microns, including bacteria, virus carriers, fine dust, and allergens. Most consumer air purifiers use H13 or lower; the SA700's H14 filter means meaningfully cleaner air, particularly important in high-occupancy environments like classrooms and open-plan offices.

Can this be wall-mounted?

The SA700 can be wall or ceiling mounted. You can choose to add on the fixing brackets and a longer cable (2.5 m).
