Home Air Filter change frequency
When a home air filter manufacturer recommends a filter change every
90 days, what duty cycle do they assume the filter wil be used? 1 hour per day? 10 hours per day? 24 hours per day? I think they should list filter change recommendations in hours (e.g. filter good for 300 hours of use). (Some thermostats like my LUX have filter-life counters that show the number of hours the filter was used since it was last changed). |

What makes the run hours any different then days, it's still going to depend on the environment. (clean/dirty home, pets, return location, etc) |

You need to change it every 90 days, unless it needs to be changed sooner, or operating conditions result in you being able to change it less frequently. I think they should list filter change recommendations in hours (e.g. filter good for 300 hours of use). (Some thermostats like my LUX have filter-life counters that show the number of hours the filter was used since it was last changed). You should be able to call LUX and ask them how many hours you can go between filter changes. After all, they put the hour meter in there, so they should be able to tell you how to use it. But then, they don't make filters, so their guess is as good as..... If they give any answer, and don't just hang up on you. At least one of the manuals they have online gives their theory as to how many hours = 90 days, and it's not any of the guesses that you've made. So, my first answer is likely to be the most correct answer. If you don't like these answers, you'll need a new thermostat. |

By the way looking at it really doesn't tell you the condition if you have
an electrostatic filter. According to Filtrete the electronstatic fibers loose their ability to atttrack the smallest particles before the filter is otherwise dirty. wrote in message oups.com...

The only thing loose is your (implied) brain because it is rattling... |

Based on EU-2 rated filter media with an area of 01121 square meter
and a face velocity of 2 m/s a pressure drop across the filter of 25 Pa would indicate a clean filter.
