Central Vacs are like addictive, like peanuts, John. You can't stop at one. Every time you move, you have to put another one in first thing.
The lack of noise, odor, allergens as well as the convenience (and fun of using it) make these systems a winner.
No HEPA filter can filter out all contaminants (even though they are very good), especially at the bacterial and viral level. Odors are caused by bacterial grouwth in the bag and you are breathing these in.
In a central vac, absolutely zero is recirculated, as any residual particles are exhauseted outdoors.
I remember the good old days when Whirlpool made vacs and central vacs. Whirlpool is what most of the builders in our area used. Of course, back then, Sears Kenmore were Whirlpools.
It still amazed me, how backward the U.S. is in the use of central vacuums systems in homes. Unbelievably, there are people out there who don't know what a central vac is, let alone have seen or used one. Compare this to Canada where central vacs are commonplace.
I mentioned this in another link. When I had Lowe's install my carpeting in May, the young assistant (about 20 years old) asked to use my vacuum for the final clean-up. (residual carpet fuzz, etc.)
I went to the closet and pulled out the hose. He just starred at me, silently, with his mouth open slightly when I plugged it into the wall and then handed it to him. He had never seen (or apparently heard of) a central vac.
He had a ball with it. After vacuuming all of the rooms of carpeting he pulled the hose off the powerhead and was playing with it. He would let the suction hold the hose onto the palm of his hand and moved his arm up and down. He yelled over to the installer and yelled "Hey you could pick up a bowling ball with this thing!"
