i have a HEPA filter with UV and supposedly it has ioniser but i don't think it does because i put grounded foil nearby and it did not get dirty... need to actually get an ioniser sometime, they aren't hard to make but kinda hard to find to buy *gets the impulse to go search amazon*

since i have a grounding mat under my feet in my work area and a grounding sheet on my bed now, an ioniser might make them get dirty but confirm that an ioniser was needed
