Great ive always wanted to sign into my furnace filter /s ...ive stopped with fancy high MERV/MPR filters and just buy the ones from furnacefilters.ca 12 pack for $60 shipped. Replace em every couple of months. Works great!
- Made in the USA
- Thicker construction so do not warp like the 3M
- Merv 8 so great filtration vs. air flow ratio (as in not hard on your furnace)
- Work out to $8 each.
Bunch of neighbours are using them now and swear by them.
For businesses they sell MERV rated filters which is the convention
For us schmucks they go and "invent" a brand new rating system and finance a study many years ago (the results of which no one knows) that MERV and MPR are equiv at the right ratings.

Yeah right.
MPR 1900 is a very high Merv, too high from my research. It restricts airflow and makes your furnace work too hard, wearing it down over time.
The MPR is 800 on the Merv 8 Nordics I posted above, so this is well over double that. Would never go higher than Merv 8, MPR 800. Just my opinion based on all the research I'd done years ago.

Anyone see the Merv 16 IQAir filters on sale ever...its for the Perfect setup.
What you need MERV16 for? Even for most ppl MERV12 is almost overkill and will stress your furnace motor. Generally MERV8 is standard and good enough for most.
I switched to the ones from Canadian tire. Merv 8. Go on sale with bonus CT money 2-3 times a year. Believe it works out to ~$4. Change them every 60 days. Thermostat reminds me. Approved by my HVAC installer and a friend that does commercial HVAC. No added stress on the new furnace and cheap enough to change frequently.
Might try the Nordic ones if a good sale pops up.
Even on sale or clearance, the 3M ones just bleed your wallet.

Do you change them every 60 days regardless of how often the furnace/AC has been used?
I have my Nest set to remind me and it's based on how long the system's been run since I changed it, instead of actual time span. My system has run very little the last 5 months.

Depends on how long you run your system, if it's not running it's not going to accumulate much of anything. I'm now trying a new approach with running the fan all the time, especially through the winter. This is the recommendation by many, keeps your air circulating and fresher and takes up less energy for the system to fire up from nothing everytime heat or AC is on. Since I'm doing this approach I'll likely swap out filters every month/30 days vs. the 60+ days I've been doing to this point.

Since May my system's run only around 65 hours tops. Most of it was in July when it was hot for over a week.
This month I've had it on only a few hours as I'm using the fireplace more.

Daughter has cardiac issues. Even the flu one year put her into heart failure. She is doing very well now days but have kept the clean air going. The IQair unit does not stress the furnace it is a 4 filter unit.

It's a smart filter that you can connect to your phone.
Adding a cheap chip and jack price up for fancy reports which are just set of alerts and nothing more than that!
Even if smart, smart bulb, smart plug etc are cheaper which lasts for years, unlike this which lasts for 3 months?

Nice price for what it is, but these filters are way too expensive for no reason and air flow must be horrible. I now buy the 24x24x4 MERV 8 pleated filters from furnacefilters.ca and theyre pretty good, 85$ for 6...

I used to change my CT ones every 6wks. Now that I have the Ecobee 3 lite, I set it at 100hr run time before I change it. I tried 200hr but noticed at 112hrs the filter was pretty filthy.
