Good deal. Just be aware unless your furnace is built for it, anything higher than Merv 8 may be detrimental to your HVAC performance.

Good point that people don't always realize. The highest I go is Merv 10 with some unique Duponts I've only found at Menards and even then only during the highest allergy months but really going forward probably just stick to Merv 8's.

Another point based on a lot of research is in most cases your HVAC is not meant to be a air quality filtration system, the filters function is to protect the hardware.

Yup. Had a higher one on mine once because of a good deal and the airflow actually started bending the cardboard. I've switched to a reusable filter and never looked back.

Unfortunately adding images via the mobile apps isn't an option yet Frown So a couple ways you can add images to your post:

1. Go to the desktop view of your post on your phone and add it in that view.
2. Add the images via a pc
3. You're also welcome to email the image or images that you want to add to me and I can upload them for you. If you chose this option, email them to my username, widgit at slickdedeals.net. And then quote me here to let me know that you did so, so that I know to go check my email for them.

This is absolutely not true. Here's why:

1. Higher MERV filters are not necessarily associated with a larger pressure drop. For example, see https://www.youtube.com/watch?v=RkjRKIRva58

2. Pressure drop from undersized ductwork is much worse, and massively undersized ductwork is all too common, especially when the furnace is upgraded without changing the ductwork (often to something with AC and/or higher efficiency units). Yet, you don't see furnaces dying every other day.

The guy who made that video seems to recognize the idea that a lower MERV rating offers better airflow (although it's a general rule, with exceptions of course). At the end of the video, he concludes with "So if you don't have an issue with allergies, going with a filter with a lower MERV rating and more filter pleats is probably going to deliver a lot better airflow."

Also, the problem with undersized ductwork is a completely separate issue. Most people bothering to do research on their air filter are likely to have done similar due diligence to make sure the rest of their system was properly sized (again, a general rule that would obviously have exceptions). At any rate, ignoring one possible problem just because there may be others isn't the best idea. And the idea of ignoring basic problems because it's not going to die tomorrow isn't great in the long run either. Sure, you can buy a new car and run it 'til it drops without ever doing any kind of maintenance on it. It'll still last for years and many, many miles. But with proper care and maintenance, they'll go much further. There are cars out there with over a million miles on them and longevity like that takes some care. That little extra care can be especially helpful for people with systems that are really old already and trying to squeeze a little extra life out of them.

Also, filter width determines surface area for pleated filters, so you might be able to have a higher merv with a wider filter with no drop, but a regular width might be a problem. Most furnaces don't give you options on width, but some do. Always want widest you can get but some people might be getting thinner ones due to price.
