So are you suppost to get the cone and consume it, or just the honey? I'm
confused when above you say "...treatment with honey cops..."

Yes, they can and should be cleaned at least a few times a year, with
filters washed and/or replaced each time.  My husband's company does
this to protect all their electronic equipment.  A side benefit is the
employees get good air, too.

Oh I have lived in all of the above but I do not think you will get a
conclusive answer.

Actually I have both right now (baseboard heaters and central forced air) and
switch back and forth.  I really cannot stand the forced air except in very
cold weather.  In mild weather it seems to blow around irritating mold or
gasses for whatever reason.   My place is really not at all dust and mold free
though - things might work better if it were.

I like low-temperature baseboard heaters a lot.  They are small closed-off
radiators. Some authorities recommend them over other solutions..  High
temperature heaters cause gasses to be given off from roasting dust.

There is no doubt that well-filtered forced air can work well but I do not
think it is the only solution.  

What if the major source of dust is locally-stirred up dust and mold within the
individual rooms?  Air filtering is not going to get rid of that.   In a
super-clean house, central filters might work well.  But presumably you would
have to leave the fan on all the time.  Otherwise it would be off all the time
if the temperature indoors and ourdoors matched.   The windows would have to be
closed.   I prefer to be able to open the windows selectively.

It is just horrendously complicated.....
