You have to buy at least 4 to get the 50% off; it's recommended to replace every 2-3 months, so this is basically a years worth of filters. Deal works on most sizes. Good reviews.

Too many HVAC guys have told me otherwise.. In fact, I'd say I've NEVER heard an HVAC guy say it's 'misconception'

When you stretch the pleats out to a flat surface the surface area may be different depending on the depth and number of pleats. You are assuming that the pleating is done in the exact same way on all the filters and that the fiber materiel is exactly the same in all the filters and that the only difference in filters is that some have more layers of material than others. That's a lot of assumptions.

Merv 8 nothing higher on hvac system, higher merv more static pressure and restricted airflow. If you wanna filter your house use an air purifier

They're all 50% off. Premium and Ultimate are the same price. Ultimate is the highest filtering, but slows the flow. Which to get?

According to their picture chart, you need at least FPR 9 to trap allergens if that is important to you. It's a misconception that the higher filtering always results in lower air flow. Frequently there is more pleating and greater surface area to compensate for the smaller holes. This is true for these HDX filters which state "Because of its unique construction, this FPR10 air filter requires less energy consumption which makes it an upgraded solution when compared to FPR 9 and FPR 7 air filters." It says the FPR rating includes a pressure drop measurement, but unfortunately they don't list the value of each filter.

Costco sells their Kirkland 2200 filters (bacteria, smoke, odors- probably ~Merv 13) for $10 each on line (? cheaper in store). I think they occasionally put them on sale in store, but I'm not positive.

Very good deal, these filters have skyrocketed in price the last few years. Perfect timing as I just installed my last 2 a week ago. In for 6 and good for over a year. Thanks OP.

I assume that you don't believe the HDX filter information either. Yes, I know companies do sometimes make false claims about their product. You might notice that some of the pleated filters are 3/4" thick while others are 1' thick. The thicker ones have more pleated filter material and therefore more surface area and therefore less resistance than a thinner filter with less material (everything else being the same.) I'm not saying that the higher MERV filters always have less resistance. I'm saying that higher MERV doesn't always imply greater resistance. I'm not surprised that you have never had an HVAC guy tell you that it's a misconception. I don't think that I have either, but I wouldn't try to educate them or they will probably be insulted.

Bro, more material, more blockage. More surface area, more filtering.

Greater surface area means less blockage. Suppose that you had two strainers. Strainer A has holes 5mm in diameter. Strainer B has holes 4mm in diameter. Strainer A is one square foot in size. Strainer B is one square yard in size. Which one causes greater restriction to water flow?

That is why the material is pleated instead of stacked on top of itself in layers. The pleating allows for a larger surface area to be contained within a fixed filter size.

There are many other parameters that affect the flow. Are the fibers slippery or rough? Are they woven into geometric blocks or randomly spaced? Is the fiber material homogenous or thicker in some places than others? Are the fibers made of exactly the same material? Do some fibers hold a greater electrostatic charge than others? Etc.

Your miscalculation is that you're not considering that the area is fixed. If they're both one square foot, the bigger hole allows more air through.
