Summary:
There is a certain appeal to a silent air purifier. Why is silence not necessarily golden if you are an air purifier. The question is, do they work?
Silent usually refers to an air purifier with no fan or a very low noise fan or another technology that makes little noise. In most cases a fan is the noise maker.
Nature cleans the air partially by using wind and storms. Both are noisy.
Most HEPA filter and filter air purifiers clean the air using fans by drawing the air to the purifier for cleaning. Again some noise involved.
Most active technologies or passive/active technologies use a fan well. Again the noise.
Most technologies either need to blow outwards to clean the air or draw inwards to clean the air. One could make an argument that active ionization could be silent, but I wouldn't
consider it a stand alone technology. It doesn't do a comprehensive cleaning job alone.
Put a silent purifier in a normal size room with minimal or no airflow and the results would be poor. Put the same air purifier in a room with moderate air flow and the results would be
better.
My recommendation is to only use a silent purifier if you have consistent, moderate air flow from a source other then the silent air purifier.
More Detail
If you object to the noise level of your purifier, there are a few things you can do.
1) Run the purifier on low when you are around and higher when you are not.
2) Get a purifier type that allows you to locate it in a place out of ear shot or at least in a place that is better suited for your "noise" needs.
3) Get a brand that has a lower noise level. Some quality purifiers do.

Buying Considerations
In most cases "wind" is a part of cleaning. Wind has a noise factor. Maybe someday someone will come out with a universally effective silent purifier. Stay tuned 🙂
