.5 ESP with two filters, so just barely makes spec. I wonder how good it would be with one point of filtration.
Of course you need to satisfy customer OCD without :rolleyes: or they might find someone else.
I wasn't promoting it I was just saying that it can be done if it was designed to do so. Same with 3m filtrete filters. As long as its designed for it then it's ok. I agree that 99% of the time the duct is not designed for restrictive filters and it causes problems.
I've decided to stick with the two 20x20 filter grilles and NOT install the 5" media filter, because it would require potentially problematic modifications to my air handler stand that might reduce return airflow.
I've also decided to try returning my recently purchased "back-up stock" of Filtrete 1" filters to Sams's Club and get the 5" if I can find them at any HVAC warehouse in my neighborhood. My son is the RE Michel manager in Orlando, so he can probably bring me one the next time he comes with the kids for a visit with Grandma.
I've tried finding the 5" filters for 1" filter grilles in local retail outlets, to no avail. Some thought I was dreaming and said there was no such thing. Others said they've not been able to "get them in" yet. I'll call around on Monday to some of the local HVAC warehouses.
Ac supply houses around here carry them in common sizes. Retail stores usually don't carry anything but 1" filters. RE Michael should have them if not I know they can get them.
]"This thought comes to us from Caiaphas, the High Priest mentioned in the Gospel of John.Quote:
"Ye know nothing at all, Nor consider that it is expedient for us, that one man should die for the people, and that the whole nation perish not."
This comes to us from Aristotle, in his "The Aim of Man".Quote:
"Even supposing the chief good to be eventually the aim for the individual as for the state, that of the state is evidently of greater and more fundamental importance both to attain and to preserve. The securing of one individual's good is cause for rejoicing, but to secure the good of a nation or of a city-state is nobler and more divine."
A more contemporary quote is from Spock in Star Trek: The Wrath of Khan;Our needs for this thread are for the many, not the one that contradicts the most logical suggestions and solutions.Quote:
The needs of the many, outwegh the needs of the few, or the one.
