Should I turn the “ionizer” feature on, in my HEPA air purifier?

I have a HEPA air filter. It has a button on it, which turns on the optional "ionizer" feature. The system is made by Honeywell (actually a company called Kaz, which sells it under the Honeywell name.)
Any information on the helpful effects of having "negative ions" in the air?

Ionize means to send harmless low electrical emissions into the atmosphere. Lightning is mother natures ionizer.
Its a negative electrical charge that causes inert particles to bond. For example, lightning causes water droplets to bond to dust particles in the atmosphere as well as other water droplets so that it gets heavy enough for rain fall.
That’s why lightning always precedes a heavy rain fall.
Same thing with your HEPA filter. The ionizer makes dust particles bond, get heavy and fall to the ground or gather in your filter more efficiently.
Some people sell professional ionizers for indoor atriums, because of bird dander. It helps the fluffy stuff in the air settle to the ground.
