Purificatore d'aria PRIME3 SAP21 20 m² 39 dB 45 W bianco

The PRIME3 SAP21 air purifier is designed for indoor spaces up to 20 m², providing filtered air with a noise level of 39 dB and power consumption of 45 W. It combines a three-stage filtration system — pre-filter, HEPA H13 filter and a negative ion generator — to reduce dust, allergens, bacteria and airborne particles, with an airflow rate of up to 145 m³/h.

Advantages

SAP21 offers a three-stage purification process that captures larger dust particles with a pre-filter and removes up to 99.95% of particles ≥0.3 µm with a HEPA H13 filter, as well as up to 99% of PM2.5 particulate matter. The built-in negative ion generator helps balance indoor ionic levels in environments with many electronic devices. The unit supports three operating modes (silent <39 dB, slow and fast) to match noise and purification needs while covering rooms up to 20 m².

Suitable for

• Bedrooms and living rooms up to 20 m²
• Home offices and small workspaces
• Rooms with allergy sufferers or sensitive occupants
• Spaces with many electronic devices where ion balance is needed

How to use

Place the PRIME3 SAP21 on a flat, stable surface in the centre of the room or where airflow is not obstructed. Select the appropriate operating mode (silent, slow or fast) according to desired noise level and purification speed. Ensure the intake and outlet are free from obstructions and run the device continuously or as needed to maintain air quality. Replace filters according to manufacturer instructions or when indicator signals a change in filter condition.

Recommendations

For best results, keep doors and windows closed during operation, run the purifier continuously in rooms with allergy sufferers, and periodically vacuum and dust the room to reduce coarse particles that settle on surfaces. Replace HEPA and pre-filters following the schedule in the user manual or earlier if airflow decreases or the filter indicator activates.
