RE: Electrostatic filter
I used to (a long time ago in a galaxy far far away) design ventilaiton systems for full smoking casinos.
Outside of the organic issues that I believe that some electrostatic filters can remove they were essentially very high efficiency particulate air filters than could remove bad stuff w/ limted air pressure drop... albeit w/ some electrical energy used for the 'ionization'. They essentially charge air particles zipping thru them one way or another and cause them to collect somewhere, either a plate or in some mfgrs they use coagaulation where the charged particles become "bigger" and get picked up by a standard high efficieny air filter. Keep in mind outside of carbon filter (help me here guys) you CAN NOT get rid of gases w/ any particulate or ionizaition filter. You need dilution to take care of this.
Once the federal/state smoking ban went into affect in public buildings this work I was doing went away. So I now do windows.
I probalby missed your question but I hope not. .......
RE: Electrostatic filter
lol .. at least u tried answering it...thank u for explaining how it works...but i need to know the criteria or how to judge if a certain electrostatic filter is acceptable for the job by just looking at its technical sheet... the use of the filter will be at a commercial kitchen for a university... any ideas?

RE: Electrostatic filter
Does the information in the filter's technical data meet or exceed the specifications for the job?
I would add: eng-tips members are not going to write specifications for you. The mechanical engineer who designed and specified the kitchen exhaust and makeup air for your particular job should have listed the data that must be met for the filter in question.
If your installation was not designed by an engineer, you need to go back one step and have that design done before hiring contractors and ordering equipment. That engineer needs to be familiar with your local codes and ordinances, and with the requirements for air quality and fire prevention in your location.
Good on ya,
