1912 - Cool night time air is dusty-Let's clean it to cool house

Two parts to this thread. I hope it will become more than air filters.
Massive amounts of night time air coming in
wants to be cleaned of dust so it will cool
the house and keep it dust free.

Let's try to make this thread the beginning of a well thought out design , DIY ideas, shared here and anywhere.

Can we talk?
And then collate the data and put it where many can review and improve it? My old house is 100 years but many houses need night time clean air.

I'm a materials scientist with a degree in electronics
and a 20yaer background in designing a few minor
analytical labortory instruments (machines).

I enjoy the basics of simple machines. I'd hope
we could keep coming up with good , nay, excellant
plans for cleaning night time air used for cooling
the house.

Don't hesistate to include ideas for transferring
heat 'Just' air doesn't carry much heat
because its mass is low.

Here's some ideas for cleaninng air. Let's just
let cool air come in through the front door.

We put some big low restriction air filters
in the doorway and the air is filtered. We
wash the filters occasionally and we have
clean air compared to dusty night time air when not using
an air filter.


The Internet lacks an ability to fine tune the
quality of the information we are getting. I suppose
Bing is goingt o try to help us. Sell us.

If you can also suggest ways to derive really good
ideas rather than lots of OK or great or not so good
ideas I would LOVE, with a big 'L' to hear them.
I guess coming up with good ideas is not hard. Getting them reviewed and finding the right inexpensive materials is difficult. I see it though. With my own
eyes twice a day I see regular people creating new
technologies that work. We, as people, could outpace
the big corporations if we worked at it. We might undercut the costs of regular business if we enjoy success and make DIY the new 'very high tech' . VHT

In the last 2 years I've struggled to get quality
results from my forum posts and searches. It's
not the people. It's the system.

So 2 things. Air filters and better data quality.

I'm here for the long haul. I want to create a better
system for geting real products into the hands of
ladies at home alone, Kids at school in their first
apartments and families with too little money and
even less time. It's almost time to 'print' 3D
machines in yours and my house and make this
computer thing turn the world on its ears.

Dreaming isn't want I want nor is living in a fantasy.

It will take committment. I retired at 46 to devote time
to this. I'm poor. But it's the best 10 years, I'm
57 next year, of my life.

Anyone who wants my attention for help just ask.

I can assist you with choosing materials based on
their mechanical or chemical makeup as well as
the way they're manufactured. I'm not an
expert in all things but I do work hard to know
what I don't know. So if I share something I
do my best to give the complete story. Again, I
believe, it's about getting quality information.

Thanks for the help with air filtration into a
warm house at night.

Maybe we should have an actual page where designs
and theories are put forth and DIY strive to refine
the ideas.

I don't think you are going to have much luck using filters designed for forced air systems. You will dramatically reduce the amount of air coming in the windows that way. You would be better off putting a fan in a screened window and buying a feather duster.

RE: 1912 - Cool night time air is dusty-Let's clean it to cool ho

Little trick I've discovered with my Mom's 103 year old Victorian...

Take a regular box fan.

Get a furnace filter. I use Filtrete filters for mold, allergins, etc.

Duct tape the filter to the fan so that air is drawn through the filter, then through the fan. Pay attention to which way the air flow is supposed to go through the filter.

Use that to filter the air coming in your windows.

Since I've done that in a couple of rooms in Mom's house the difference in dirt and dust has been dramatic. The dogs used to drag in a fair amount of dust, they shed, and the house has always been dusty.

Air quality is a LOT better.

RE: 1912 - Cool night time air is dusty-Let's clean it to cool ho

I have HEPA air filters in multiple rooms of my house but it is still very dusty. I thought it was because the windows were open earlier in the year, because this is a dusty environment (Sierra Nevada mountains) but the windows have been closed for a month. There isn't forced air here, so it isn't the ducts. I vacuumed an entire bag's worth of dirt out of the carpets the first two months I lived here with a brand new Miele vacuum. I fixed the dryer vent which leaked. The dust still appears overnight! Help! I like the idea of a filter before the box fan although I am going to have to come up with something more attractive than duct tape to make that work in my bedroom!

RE: 1912 - Cool night time air is dusty-Let's clean it to cool ho

have a blower door test done on the house
to find leaks that allow dust inside.
tightning the leaks will make house easier
to heat & cool.

old thread..wonder what happened with OP!
