When the air outside seasonally is literal poison due to multi-regional wild fires, yes it does.Is air quality in cars really a problem? I never noticed.
I don't. Is the fancy filter mainly intended for sensitive folks?You clearly don't have allergies.
This is something I can confirm with real world, and very recent results.I don't think I'll be in a hurry to change. The current one seems good. And more restrictive filters are usually harder on the fan.
[Putting on my HVAC tech hat] - Your home HVAC should not have a HEPA filtering all the airflow unless it's one of those IQAir boxes with the crazy expensive filters ($400 for a set every 1-3 years). Personally I would change the setup so you can go with a single 4" MERV 11 filter that costs $25, that's plenty of filtration for most people. A bypass HEPA system is much better idea because if it gets clogged the main fan still gets full airflow.This is something I can confirm with real world, and very recent results.
My home HVAC air handler had 2 filters in it. The cold air intake filter and a air handler HEPA filter (I wasn't aware that the HEPA filter was installed as it is under my house).
A little background:
4 days ago my heat pump stopped pushing cold air. Breaker tripped. Reset the breaker. A few hours later the breaker tripped again. I checked the main filter and it was dirty but not too bad, so I changed it to be certain it wasn't a problem. Reset the breaker again and timed it. 3 hours and it trips. Called the HVAC company that installed it and opened a service ticket. They said it would be almost 3 weeks before they could come. Ugh. It was 90 F inside my house.
3 days later HVAC called and said they are on the way. Had a cancellation. Wonderful! The tech inspected the main filter and said it looked good. No leaks or gaps. He checked the heat pump and it was also healthy.
The air handler was the problem. The HEPA filter was so clogged the air handler fan blew out the limiting resistor and it kept shorting out and tripping the breaker after the motor got hot enough.
Results:
The advance HEPA filter did $3800. The installers knew it was there it was not disclosed to the owner.
If high density filters are not serviced frequently they will damage the fan motor.
The point wasn't to derail the topic but point out increase fan motor wear with thicker filters.[Putting on my HVAC tech hat] - Your home HVAC should not have a HEPA filtering all the airflow unless it's one of those IQAir boxes with the crazy expensive filters ($400 for a set every 1-3 years).

If your ducts are under your house I can almost guarantee that you have air leaks that are going to negate any kind of HEPA filtration in a hurry.
Airflow is king for HVAC, if you have limited airflow you will have limited heat transfer.
I purchased and installed one too (based on your advice). So far, I think it does a much better job than the OEM filter.I've been impressed with the aftermarket Pureflow filter I put in my Mach-E. Has definitely helped with nasty outside smells.
Yep. I've had multiple service techs tell me to ditch the fancy furnace filters and use the old cheapies (usually the basic blue ones). Which is exactly what I've been doing for years. I buy them by the case and change them every month or two. Much better on the furnace blower. And the air is plenty clean enough for our tastes. If we had asthma or something, it might be different, but we don't. We just want it to be reasonably clean. The stock filter in the car seems just fine now.This is something I can confirm with real world, and very recent results.
