A Dentist is always the most prone professional person for aerosols transmitted infections including viruses like Ebola, SARS, COVID, influenza, etc. In spite of taking maximum protection like a face mask, head cap, gloves, and apron, he is still prone to aerosol transmitted viral infections.
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.

Comparison of a 200 Watt High Efficiency motor and 1800 Watt motor
The electricity cost is $0.15/kWh * 1800 hrs * (1.8-0.2) = $432 with assumption of 1800hr run time and utility rate at 0.15/kWh
Learn about the warranty available for the unit you are considering. Normally the cosmetic and consumables are not covered in Warranty.
5.Indicator Lights or alarm for Filter Changes:
Some units have them. It's not necessary, but is kind of convenient.
You want this to be as low as possible, but realize some of the high capacity aerosol suction units do make noise. Working in a noisy environment for a long time can be painful. Also make sure the unit come with speed adjustment function to lower the noise level if necessary.
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.

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.
