House Dust

House dust is an issue most people deal with.for most homes,dust accumulates slowly,taking several weeks.
But,what do you do when dust accumulates within one day
of a complete cleaning?dust that can be seen,and collected.
the problem house is a 1450sq ft ranch,with a full basement.
it is 14 years old.I had the house built.I am the first,and
only occupant.no pets.it has central heat,and a/c.the
furnace is fueled by propane.the attic insulation is
blown in.no duct work exists in the attic.the dust problem
began within the first year.the furnace is equipped with a
hi efficiency filter.I also have a fresh air exchanger.I
sealed all the gaps in the furnace ducts.the cloths
washer and dryer are located in the basement.
there are 3 rooms I dont use.I keep the doors to
these rooms closed.dust will not accumulate in these
rooms as long as the doors are closed.the house is fully
carpeted except for the kitchen.knowing the composition
of the dust, might even lead it's source.

I suspect that one or more of the ducts are split and drawing in dust/dirt from the surrounding area. Another problem may be the locations of the return air inlets, anything down at the floor is going to pick up more dust/dirt than an elevated inlet. Filters in a furnace are not tightly sealed, a significant amount of dust can be drawn around the filter, especially when the filter becomes partially plugged, therefore it is important to always keep your filters clean.

All of the duct work for the furnace is visible.if there is a
split,I dont see it.I forgot to mention the return air ducts are high on the walls.the return air ducts are actually the spaces in between the studs.
Thanks for your response.

Re: House Dust

How does your "fresh air exchanger", or better known as a heat recovery ventilator, dump the fresh air into your home? That might be one source of your dust. I've seen where the heating system is pulling air from the attic (insulation dust) but your filter should be loading quickly if that were the case.

I'm not sure how anyone can completely collect dust while cleaning.
If you use a vacuum cleaner then you are blowing dust around while you think you're sucking it all up, unless you have a super duper hepa micro high Merv filter. Carpets collect dust contrary to what you think when you vacuum.
Have you cleaned the heat vents at the boots?

The fresh air exchanger gets it supply from a screened port thru
the side of the house very close to the basement window.

I am not sure what a heat vent is?

I use a bagless vacuum machine.after the dust,or debris is collected,there are 3 filters the air passes thru before leaving the machine.

Yes, I know that it brings outdoor air (and dust) into the house.
My question is: where does the "fresh air" enter the house?
Normally it's into the return duct (to be filtered), but not always.

Thanks for the reminder.

I dusted about 2 years ago and in looking around it may be time to do it again.

That's very helpful, thank you so much.

fresh air enters the house thru the return duct located on the furnace .it is filtered before entering the house.the fresh air exchanger also has it own filter.

Right. Thank you. I'm at a loss as to how the dust is getting into your house. Is your hi- eff. filter getting dirty, quickly?
