No Cabin Filter? Add an Air Purifier
If your car isn't equipped
with a cabin air filter, you're
not out of luck—you can still add an
ion purifier. Ion purifiers generate billions
of negatively charged ions that attach to
viruses, bacteria, dust and pollen. The particles
are then attracted to positively charged surfaces like
your plastic dashboard. Once they settle, it's just a matter of
using a spray cleaner on all the hard surfaces to wipe away the
pollutants.
We conducted a quick Internet search and found several different
types of automotive plug-in ion purifiers. We chose one
that plugs into the cigarette lighter. It comes with an extension
ion generator that attaches to the louvers on a dash air vent.
That feature allows you to direct the flow of ions toward the
passenger seat or the backseat—important if you carry passengers
with allergies. And because it works with the car's blower
system, it doesn't need a built-in blower fan like some other
units.
