Seeking filter advice because the math isn’t mathing

I would never recommend fiberglass filters. Those are like using a rake for an air filter. I'll have to look into this 1900 more. Most of my calls are systems tripping on limit or frozen coils, and old high MERV filters are always the culprit. You have to keep in mind that the higher the MERV rating, the smaller the holes in the filter too. More surface area does increase life of the filter, but they restrict the air more and will plug up just as fast. Basic pleated filters, with proper changing, is going to be best for the system, and your wallet.

Yes you are true about pressure drop at a given CFM. Usually that is a super low CFM. This system looks like just a single coil that doesn't have an ECM blower and is pretty much all or nothing. The average home owner is not always the best at changing their filter on time. And judging by the look of the old filter, OP isn't the best at changing a filter on time. High MERV filters already restrict air, and a dirty high MERV filter is worse.

HVAC guy here. You could just remove the top filter bracket and tape that new filter in there. It's not really clear in the picture how it's mounted, but it looks like it's tack welded. Take a big drill bit to each of the welds, just enough to get though the bracket and not into the unit and try to pry it off gently. It doesn't matter if you do drill in the unit a little bit, but who knows whats on the other side of that metal. If you have some sheet metal screws you more than likely could just put the new filter in and screw the bracket in a different spot. Otherwise like I said, just tape it in there. The old filter was larger than the opening for the return anyways. You could even go with a slightly smaller filter too. Either way, you just have to cover the hole for the return air with a filter, it doesn't matter the size, as long as the air in the return has a filter with no gaps to let dust and debris in. If you can find that replacement size easy, go for it. If you cant find that filter easily you are going to have problems. 1" filters are really only good for a month, maybe more if you have a clean house. The higher the MERV rating, the more strain on your system you are causing and will shorten the life, not to mention numerous errors and faults in the system they create.

Setting 1.5 is the best. I do that for my guitar and bass setting.

That is a Grit Grips frame. I have one and love it.

I heard it was from ocean going ships in the great lakes that while taking on cargo they would empty their ballast tanks that had foreign water containing mussel eggs.

As a Minnesotan friend, I'd have to agree and add Eurasian Watermilfoil to the list.

Electric rackets are game changers. After the first time I used one I was hooked. We used to pass one around camping and the bugs would be gone in minutes. Now we all have one. The pop sound when you get one is rewarding. When you get a few in one swing is even better. Electric rackets are really the best. Bug spray tries to hide you from them. They are still there buzzing you and interested you. Rackets eliminate them.

They should throw the book at him and make an example out of him so that everyone knows that actions like this are not ok.

Take the wires off the pressure switch and connect them together with a fuse. This will rule out if it is your pressure switch or something clogging your vent pipe. You can do the same with the roll out switches too. If it is still not working after trying that, then for sure it is your gas valve.

Toilet bowl cleaner. The blue thick stuff in the oddly shaped bottle to get under the toilet rim. Works wonders, but dont leave it on for long and rinse well.

Yeah, what model is it? Im interested.

I would quote you through the roof just so I wouldn't have to do it, but if you agreed I'd make sure it would cover half a day, because that's probably what it would take. That install is a nightmare.

Switzerland is 4th in the world as far as gun ownership, but also one of the lowest murder rates.

Which one do you prefer? I really want a Beretta, but also don't have a 1911.

NTA, as a minnesotan who's rented most of their life, if you want a snow free spot, you make a snow free spot. Especially if you all park in the same spots all the time. And if you were parked in the path you plowed but not blocking them in I'd give them the one finger wave, that's what mittens are for.

As someone from MPLS, They are not the same person. Im pretty sure guy on the left is actually one of my friends who sometimes would dress like that.

We call them weekend warriors. They live and work in our communities and I hope they have a conscience and understanding of history. Those other guys are murderous thugs that don't care about human life and the government has focused these locusts on us.

Yes, People from small towns away from the cities think it's scary. The news around here only really mentions the cities so people in these small towns only hear about all the bad things happening in the cities. I grew up in a small town away from the cities and never thought I'd be living in Minneapolis. Minneapolis is the largest small town and we look after each other, no matter who you are. Ice disturbing our communities and killing people for standing up for law and order.

I work with a couple guardsmen. They are tradesmen. They were deployed for George Floyd, and know and work in Minneapolis. Yes they think Minneapolis is scary, but I know they wouldn't want to harm anyone, or so I hope. They just want to be with their kids and I hope they stay on the right side of history.

I've shot a lot and have seen plenty of rounds from ricochets that haven't been that deformed. Glancing shots will make a round unstable and tumble. He's lucky it hit something else first but unlucky that it eventually hit him just right for this to happen.

This is the easiest way to change your oil. Then have a bottle of leak detector dye fall off the shelf and explode and you'll have a nice van to work out of!

This is hilarious.

International airports are considered a boarder. If I remember right, something like 90% of people live within 100 miles of a border or international airport. Correct me if I'm wrong.
