How Dirty Is Your Air?

Some indoor air purifiers have particle count sensors that activate the purifier fan.

BTW - anyone have recommendations for an air purifier with a true HEPA filter?

I've heard good things about this: http://smartairfilters.com/en which is really just a fan with a HEPA filter attached to it.

Was looking them earlier - really like what they're doing (back to basics - airflow + HEPA Filter) but prohibitive shipping costs to UK/Europe from China

I have both the HEPA air purifier and energy recovery ventilator from these guys: http://purifresh.com They work pretty well (keep my wife's allergies in check) and are simple but well-constructed units.

Edit: but they are US based so shipping may be equally expensive to the UK.

Unfortunately all the ones I've seen give wildly inaccurate readings.

Living in China I've measured particle count way too many times with different sensors. :)

I was looking at this a few days ago http://www.philips.co.uk/c-p/AC3256_30/3000-series-air-clean...

It has good reviews on Amazon, but it's not cheap.
