Why no universal sizing for these furnace filters!

Have purchased Filtrete filters for our home furnace before, but apparently, not all manufacturers know how to measure accurately. We’ve used 16X20X4 before, but when we had a new furnace installed, THEIR 16X20X4 measures out at 3 3/4” instead of 4”. Am wondering if you make a filter that fits the 3 3/4” framing instead of a true 4” depth? Would I recommend these filters?Measure FIRST; don’t destroy one. Too expensive to lose.
Been using these for 6 years. They do the job but the 6 pack price has increase 60% in that time. If that rate of increase continues think I'll start looking for an alternative.
This filter was restrictive enough to cause my evaporator to start icing up. Should be labeled that a HVAC technician needs to adjust refrigerant charge or up the speed tap on blower motor.
No, I would not recommend this to a friend.

We have used these over the past four years. Have allergies and noticed the difference once we started using filtrate. Just wish they sold them in a 6 pkg. We bought the 20x30x1.
