Right? Thinking back to the Maytag i just disassembled/reassembled...I realize the air flow starts at the bottom of th machine, circulates through the drum, then is pulled back down into the nether regions below and out the back...like most vented dryers. What up with that? No pre-filtration of any kind for air pulled from the (likely) dustiest place in your house. Imagine drawing air down through a (cheap and universally available) furnace filter, then into the drum...makes more sense to me. CLICK HERE TO GO TO stricklybojack's LINK

One thing europeans (mostly) don't have to worry about. We were (mostly) raised with condensing dryers, so we are used to much more maintanace then 2 filters... | ||

all the more reason to keep the area around the dryer clean.....not only dust and such, but things that would block the flow of air intake as well....
I keep waiting to see a sort of sealed combustion for a dryer, pulling air from outside, and returning it outside.....as not to take away inside conditioned air... that would require two vent lines..... | ||

The very fact that it's the dustiest place in the house argues that the dust isn't being sucked into the dryer, I think :-) | ||

I'd look at it this way, if this really was a serious problem, wouldn't someone have addressed it already? The air doesn't really go through the clothing, most exhausts out of the dryer. It would be comparatively easy to add a filter, but nobody ever has. Perhaps it really isn't a problem. Perhaps if you had the dryer in your wood shop ;)
The problem I'd like to see addressed with a dryer is to pull the intake air from outdoors. When it is crazy cold or hot/humid outdoors, it bugs me to have to exhaust all that conditioned indoor air outside through the dryer vent. As with all the high efficiency furnaces, I'd love to see an outdoor air intake added. | ||

I like the idea of pulling in fresh air from outside, great idea Martin! You would have to be careful of not picking up the moist air exiting the exhaust vent. There's dust you can see and dust you can't. What people are typically allergic to is the later type...which is an ever present fellow traveler of the first. Such dust is so small it is essentially an aerosolized irritant to folks like me. Quality bagged Hepa vacuums (not the leaky typically bag-less junk) are a massive improvement for allergy sufferers because of the microscopic nature of dust mites...the 'active ingredient' to household dust. | ||

No idea if it was "factory" or not, but at least one dryer had followed your idea. Here's the back panel of a Maytag 641C that maytag63 restored, that had a mesh filter over the air inlet vents. I saved the link because I thought it was a good idea. http://www.automaticwasher.org/cgi-bin/TD/TD-VIEWTHREAD.cgi?49163

Clothing always smells fine to me... I never really considered the quality of the air the dryer was using. One thing I often think about is the extra-expense of using the dryer in the summer. With my inside laundry room the dryer is sucking air-conditioned air out of the house which means 110+ outside air is being used to replace it sneaking in from various places like windows, doors and even the range hood. A garage laundry area would eliminate that problem but it does get uncomfortable out there. At times, I'm sure it would be possible to dry clothes just using the "air" setting. Another thing I've considered is closing the laundry room door to the house and cracking the door that goes into the garage. I guess it's just a matter of how cheap you want to be.

Joe (twintubdexter) said: "At times, I'm sure it would be possible to dry clothes just using the "air" setting." No kidding, particularly if you get 110F in summer -- some of the newer dryers use about that temperature on the lower temperature settings. | ||

Exactly, Duke -- maybe they are waiting for a revision on the building codes. Certainly they'd have to get at least the manufactures to promise making dryers that had the necessary plumbing. | ||

Paulo, Most dyers can be retrofitted now ,even old ones.The 4" cabinet knockouts are a perfect fit.Most have/had these. | ||

yet odd, in manufactured homes(mobile homes), behind the dryer is an air intake vent to allow the exchange of air, at least in the general area, without sacrificing that much conditioned air...these homes are sealed tighter than most wood build homes.....this vent is needed for other vented items like bathroom vents and range hood vents....even opening and closing a main door can cause a sort of vacuum to the interior...
I don't run the dryer in the main bathroom when heat or A/C is on, only on days where we have the windows open......and when using the units in the basement, I crack a window open, and close the door to the laundry room..... one dryer is bad enough, but running 3 or 4 at a time is a substantial amount of conditioned air that is being exchanged.... | ||

That smartload dryer has a few drying options to include manually set timing.That's what I would use when it's 100 degrees . | ||

Martin , You are 100% correct.That is considered make up air required for that mobile home's application per the federal government--Yes thats right,The feds . | ||

I guess a clothesline would solve everything Outside temps in the summer reach 110+ all the time, but in my non-air conditioned garage it never gets more than mid 90's. The garage is insulated and sheet-rocked like the house. The garage door is thick and insulated and seals very well. Still if I could get the dryer to draw air from the garage it would be economical. I suppose if I closed the laundry room door a very small percentage of air might be pulled from outside through the laundry room vent fan...probably not enough to make any difference. I have a feeling that installing a vent in the door that goes to the garage would be taboo. By law it has to be a "fire door". | ||

Palm springs with it's 70 degree average temperature would make me care less about a dryer.Hot days??Why not a clothes line . | ||
