Without getting into the science, if you have one filter with a flow resistance of x, then the flow resistance with four filters would be x/16.  Resistance varies by the air speed squared.  The fan will last longer because it works 1/16th as hard and the filters last longer because there are four of them. 

Sadly my sister was a hot noodle sticking to the wall.  She fell for just about every scam including sending thousands overseas.  She was too embarrassed to ask for help. 

Back before Walmart sold groceries I lived next door to one of the HEB vice presidents. She was very worried about Walmart, but once they got in, it was “nahhh, we’re good.”

The HEB at Lincoln Heights in San Antonio is in building originally occupied by Albertsons in the 80s. Currently they are expanding their presence in both directions of the strip center buying out the leases for a liquor store and Hallmark store. It was a decent sized store, but not like their new ones. The HEB at Oak…

I wonder how many drones got smashed against the firetruck. 

Yes, they are about to have their asses handed to them by HEB. The opening day of HEB in Frisco - $1m sales in one day (according to Dallas Morning News). Everyone wishes they could be HEB.

After looking at about 50 houses, we bought a house in San Antonio a little over a year ago. The problem with most of the houses was they were remodeled poorly. One looked like they used used motor oil as a stain on the hardwood flooring. They were very proud of it. One house was literally broken and heaved back such…

In the 80s, right before AIDS, I dated a woman who told me up front that she needed sex every day. Since we were geographically separated I knew I wasn’t going to be the full time stud. She and another girl friend were active on the side, twice a week after night classes. One day I asked her how many partners she had…

Haven’t heard scuzzy since the 60s. Is it back, is the author ancient?

I watched it last night on a relatively small screen and thought it was excellent. Watching it again tonight on full screen 4k.

Gave you a star, because that really made me think. 

Thanks. Always open to education.

I got to sit in on a technical talk on river flow dynamics a few years ago. With the advances in elevation mapping using lasers, they are able to characterize water flow through the river banks, but what they are trying to do is characterize the effect of foliage growing in or along the river banks. They know it slows…

Hi Bill. Do you know what the differences are? Serious question. I see a lot of common names used for different chemicals and am interested in the differences in industrial chems versus consumer chems.

My context checker isn’t working.  We actually GO through a lot of baking soda.  We don’t got through it. 

This is way off the dishwasher topic, but, things have changed for cars. The ‘drying agent’ used in car washes is available, highly concentrated, by the gallon, at O’Reilly’s Auto Parts for under $30.  Hmmmm, would this work in the dishwasher?  Might not be food grade car wash drying agent. 

Weird you should post about dishwasher chemistry. Just yesterday I was looking at YouTubes for rinse aids for car washing. When you do that search you get a lot of hits for dishwasher rinse aids. The DIY hack for that is to dissolve citric acid crystals in water (look it up for details). At first I thought that…

reuthermonkey, you clearly don’t own a cat.  We got through a lot of baking soda keeping the house smelling fresh.  That stuff is amazing!!

“You’re kinda missing the point dipshit.”

OA, I would suggest you keep an eye on your water drainage situation with the additional 4 tons of dirt. What happens, and my current house is a great example, is if the soil is out in the yard, it forms a dam which causes rainwater to collect at the base of the house and not drain. The best solution is to have a…
