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?
- shawnps 10y agoI've heard good things about this: http://smartairfilters.com/en http://smartairfilters.com/en which is really just a fan with a HEPA filter attached to it.
- dharma1 10y agoWas looking them earlier - really like what they're doing (back to basics - airflow + HEPA Filter) but prohibitive shipping costs to UK/Europe from China
- imaginology 10y agoI was looking at this a few days ago http://www.philips.co.uk/c-p/AC3256_30/3000-series-air-cleaner http://www.philips.co.uk/c-p/AC3256_30/3000-series-air-clean... It has good reviews on Amazon, but it's not cheap.

- colanderman 10y agoI have both the HEPA air purifier and energy recovery ventilator from these guys: http://purifresh.com 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.
- tellarin 10y agoUnfortunately 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. :)
