Yepper, been using these for 20 years plus. Inside of my Air handler is perfect and running great. Only thing cheap filters will get you is an expensive cleaning bill. Why do you think there are...

Exactly. Best to trust actual HVAC engineers and objective testing. Check your specific system, it should be rated. Most modern systems are rated to handle Merv 11-13. Stop listening to all the...

So much random info pulled out of butts here. This has been tested in real life conditions. Why is that so hard to understand? Engineers can and have designed HVAC systems to run with higher...

Your HVAC guy is either trying to sell you filters or just dumb. The common sentiment is "less particles going to the condenser the better" but that's not the case. Your ac is only worried about...

Bummer. Yeah it pays off to look over the shoulder of the HVAC man and ask a few questions when you have a new system installed or upgraded. They may look at you with a sneer but whatever. Any...
