Well, i agree and disagree, the ozon issue may be exaggerated and one has the weigh out the potential harm from EMF against the impact of air pollution.
But what we measure depends to begin with on the meters one uses.
I have a whole bunch of them and actually do not trust any really.
Apart from that, meters and antennas are limited to certain ranges of frequencies, and also one needs experience and some knowledge to use them and evaluate the results.
Clean air is without doubt vital of course, likely even more so for ES-folks.
These ionizers probably helped you a lot to survive in urban areas.
Not to recommend to buy something from this company, but here i found some general and clear introduction into air-cleaners :

A good filter to be placed at the four corners of one's property would be this one :

Thanks to regulation that forces the car-industry to reduce the visible smoke-levels, we suffer these days from more ultra-fine chemical particles ( with diameters below 0.1 micrometer / 100 nano-meter ) than ever before.
And these happen to be the worst, as one could guess, while high concentrations are found as tiny as between 5 and 10 nano-meter.
I watched last week an interesting film mostly about air-pollution ( unfortunately in Dutch but with English texts ) :
