Finally! A thorough explanation of what I’ve been trying to find out for a few years now. I’ve worked for an HVAC company for two years and this was more informative than any explanation given to me in the past. THANKS!

I run a MERV 13 to 16 depending on the season. I also buy 1/8 foam weather stripping that I put on 3 sides to make sure air can't bypass the filter. Since I also use masking tape to seal the forth side it has kept my unit dust free for 9 years when I checked it last with a 360 flexible inspection camera. My unit shook like crazy when it first ran and the tech blamed it on the MERV rating of the filter. It ended up being that the installer didn't remove the shipping bracket on the blower motor just like you have pointed out in other videos. Since the gaslighting was so bad and the install was so dangerous that my unit was red tagged and the unit was condemned, I just took the time to learn everything I could about HVAC systems to protect myself. I love that your are sharing knowledge freely to help others out that have felt helpless to the role authority abuse from nefarious certified experts.

A lot of filters work about equally well no matter which direction the air is going through them. For most typical filters, the main reason to make sure the air flow direction is correct is that the filter is more heavily reinforced on one side. The stress on the filter goes up as the filter gets clogged, which makes the furnace tend to suck the filter into the duct. You want it in correctly partly because that extra reinforcement on the 'lee' side (the low-pressure side) is designed by the manufacturer to keep the filter from bowing or collapsing entirely. You really really don't want the filter getting sucked into the distribution fan!

Thank you for your valuable information. I know most of your non-technical maintenance you share with us but it is peace of mind when it is confirmed by your videos.

Great Info, I bought my present home a couple years ago and I didn't even think about the filter when I first bought it but I out afterwards that it had no filter and the previous owner had been running the system without a filter most of the time.

Love this channel...and I knew ZERO about A/C units until I stumbled across this! Another great video for the layman. 👍

Great information! Thank you. I replace mine every 30 days. I simply change it when I receive my electric bill…makes it easy. May seem like overkill…but it’s an easy way to remember and I do have several cats and a dog.

Thanks; for the video. Great information for everyone. Also during the cooling season especially we need to put some bleach down the drain line to keep the slime from building up and plugging the condensate drain then flooding and possibly ruining a floor.

I upgraded to a Merv 11 in Sept 2018. Big difference.

Been using a Honeywell F50 for 30 years and is works great. SP is .1 and filters down to 1 micron, when dirty cells go into dishwasher. Evap, ductwork is never dirty.
