Before finalizing an external oral surgical suction unit one must understand its mechanism. An external oral suction unit has two main parts.

Suction unit: Suction Unit arm length must be long enough to provide enough space to work together with assistant. 4 hand dentistry needs at least 1.5 meters or above suction arm length. Heavy power above 1000 watt gives more power to suck aerosols.

Sterilizer unit (Like Air Purifier): To disinfect the aerosols sucked, a good extra oral suction need 4 main filter mechanism. Primary filter+ UV light+ Plasm Ions + HEPA filter.

Tips for choosing a mobile aerosol suction unit

Don’t be misled by the number of negative pressure. Check the rated airflow (CFM or L/min). The greater airflow rate, the higher suction air velocity and dynamic pressure.

Choose a device that uses a HEPA filter,the gold standard for aerosol suction units to capture the airbone.

Make sure there are UVC lights for additional disinfection.

Find a product with good after-sale support and reputable manufacturer.

Figure out you want a more flexible suction arm or the one can last longer and better look.

Look at noise levels (listed in decibels) in product specs. Depending on where you're using your aerosol suction unit, you may want a quieter device. Check if the motor speed can be adjusted to lower the noise level.

Calculate the aerosol suction unit's ongoing maintenance and electricity costs so you can budget beyond your initial purchase.

Skip the bonus features, such as app integration, foot control and plasma, unless money is no object.

Figure out where you want to place your aerosol suction unit so you can choose the right size for your space.

Does the unit have a pre-filter and middle layer of filter to increase HEPA filter efficiency? A pre-filter and middle layer filter can make the HEPA filter last longer with better efficiency.

Size and Look of the Aerosol suction unit: Some aerosol suction units are big and ugly. Others are sleek and pleasing to the eye.

8.Choice of suction duct/pipe

Some people like the convenience of flexible duct. But many others prefer the better looking and sturdy aluminum arm. Based on our observation and experience, the flexible duct doesn’t last as long as the aluminum arm/pipe.
