That’s what comes to mind for most people when you mention a filter in a house.  One of the first things you should do when taking possession of a house is to change the furnace filter.   Think about it – it’s got other people’s dust and dander on it.   Start fresh.   Write down  the size and note which way it’s installed.  With some filters it matters which direction the air is flowing, so don’t get it backwards.  Check your furnace manual to be sure what you should have.    Most large hardware/home stores carry the standard sizes.   Replace it at the start of each heating season, at least.   If you have central air conditioning, this filter will be catching stuff year round. Check it monthly and change it if it looks dirty.

High airflow helps reduce strain on your heating and cooling system and requires less energy, which can translate to savings for you! When a filter becomes extremely clogged, airflow through the filter begins to slow, which can force an HVAC system to work harder to compensate. Replacing a disposable filter every 60-90 days can be inconvenient and expensive—instead, you can simply rinse clean your K&N lifetime washable furnace filter to help keep your HVAC system running smoothly.
