Use of Antimicrobial chemicals in air filters - is it safe?
Many residential and commercial HVAC systems and standalone air
purifiers use filters that contain a form of antibacterial/antimicrobial chemical treatment (eg. Bionaire/Holmes models use the Microban/triclosan treatments). Is the usage of such chemicals on the filter surfaces truly safe for the inhabitants' long-term health? Is there any risk of evaporation/transmission of any of the antimicrobial chemicals into the outflowing air, and thus risk of potential health risk due to the inhalation of these substances? Or do these chemicals dissipate so quickly that there is ~zero net chemical or evaporative outflow after a few days' worth of usage? Thanks, Michael |

Maybe you need to contact the manufacturers of the chemical agents and get the MSDS for them. |

Thanks, Michael IMHO, I thought the 'treatments' were to prevent stuff growing on the filters, and do not release into the air. That was my observation about some material I read. later, tom @ www.Consolidated-Loans.info |

The US HVAC professional organization (forget its actual name) recommends MERV 13 or higher. I've seen some MERV 11 around here for a good price. 3M doesn't use MERV ratings but apparently the "1250" rated ones are MERV 11... Peace, Dan |

Thanks, Michael Michael- I believe "/triclosan" is the active ingredient in most anti-bacterial soaps...it's probably safe but I avoid the use of them..... because by using them we contribute to the "breeding" of super bugs just use plain old soap (non anti-bacterial) it works by washing bugs away not killing them do you want triclosan resistant bugs in your house? IMO just use a good (3M ~$15) filter & cahnge it every couple months Instead of paying the $$$ for the 3M brand name filters, use a generic or off brand MERV 8 or 9 pleated filter, and change it every month. or get a "pemanent" washable electrostatic unit. I don't recommend these at all... they create too much restriction in the air flow, and with the half dozen layers of media, there is no way to get it absolutely clean without complete disassembly and washing it out with an anti-bacterial/microbial cleaner then reassembling it. I just hauled a 3 foot tall stack ofthem to the dump.... if you hurry, you might still find a couple of them there in your size. cheers Bob My electrostatic allows the guts to be pulled & run thru the dishwasher....seems to be pretty easy & comes out clean (rinse water clear) both the 3M & the electrostaitc seem to work ok since the houses don't have dust problems inspite of the occasional construction projects cheers Bob |

I doubt they are trying to evaporate bactericidal stuff into the air, that's not a real workable idea. I figure molds and such are going to be more of a problem than bacteria growing on the filter, and they're harder to kill than bacteria. I figure, if my filter is so dirty it's growing mushrooms, I better change it. |
