How many hours of usage can you expect from a 1 month or 3 month furnace filter? My new thermostat has a feature that counts up the hours of usage the furnace and A/C have put on a new furnace filter and, when it reaches a certain number, flashes a warning light to let me know it needs to be changed. Unfortunately none of the filters I've shopped for have an "hours used" rating, simply "30 days" or "90 days" (which has nothing to do with the actual usage of the filter). When a filter says that it's good for 3 months, how many hours of usage can you really expect out it?

Where to put the filter for my furnace.....? Long story short, I rent a duplex and it hasn't been changed in a long time. I've never done it and there were 2 filters sitting side by side in the duct and basically not doing any filtering. So my question is should the filter be right by the return air vent or closer to the furnace? It's kinda hard to explain how my set up is. Basically a vent in the wall up by the ceiling, goes through some duct work approx 2 ft then a 90 degree drop down to the furnace. The "access hole" to get to the filters was only a small hole about 6"x6" and the filters that were in there were 16"x16"

An oil furnace with an electric air filter. The furnace works fine, but the motor constantly runs. Problem? I am not sure if it is the motor that circulates the air, but it is on 24/7. There is a plug for the air filter which when I unplug it, the fan still runs. The only way to shut off the fan is by a switch that is located on the outside, but that turns off the furnace as well. Isn't there supposed to be some sort of timer that turns the circulation on and off at regular intervals and also is on when the furnace is heating?
