How do you determine when a furnace filter needs to be replaced?
I am investigating using the pleated filters in my furnace. The problem with any filter is knowing when to replace them. Most tell you how long they should be in the furnace before replacement. It seems to me a better method would be to measure the low pressure on the blower side of the filter. As the filter becomes plugged the pressure would go down while running. Does anyone know of a device to do this or does anyone know how I can determine what the maximum pressure drop should be across a filter when it needs to be replaced?
Filters are to be replaced at the least every other month. It really depends on the area you live in. The type of filter you use makes a difference also.
If air cant travel through it due to the millions of dust bunnies and particles that have been trapped...then its time to change it.
Be careful with the pleated filters. They come in different densities so be careful not to get one of those 1200 's which is very dense.
True the higher the number the more particles it will catch. but at what price ?
Try this : while the furnace is operating take note of the sound of the air movement. if when you remove the filter (if possible without having to leave the cover off) there's a significant release of air pressure, then the filter is too dense. This will reduce the efficiency of your furnace, and also reduce the life of the motor. This is because the dense filter is causing the motor to overwork. This is to the equivalent of having a dirty filter, where the air is restricted.
Its a little technical and cost a bit , but there are meters that measure air flow or CFM's. Fluke puts out one. I think they are about $ 300.00
Also be careful of those cheap blue filters that allow too much to travel through. this will fill your ducts with dust and dirt. If you have central air the dust and dirt will get caught in the coils and soon not perform at its best , because the coils have become your filter and trap the dirt that the filter misses.
Or cause you to have to have duct cleaning. So I suggest not going to the extreme either way. If you use pleated, try one thats rated at 600. If a different rating is used with pleated u can go the lowest number . It should suffice.
