You gotta research your filter's pressure drop. Usually, more pleats = less drop. Pressure drop just means the fan will add more power to keep the flow rate up. Higher MERV rating also means more pressure drop. That's why you use one with more pleats or use a much larger filter in a proper filter housing - to reduce the face velocity of air going through the filter, which helps reduce pressure drop.

A tangent on merv ratings. I use merv 13 (yeah the cheap filterbuy amazon 4 pack $69 and free shipping) when I build a Corsi-Rosenthal Box but of course that is only attached to a standard box fan. I am not sure if cheap or not will make a remarkable difference in energy used for that. Though I wish I could find a merv 16 that was still 20x20x2 and wasn't expensive.

I do HVAC for a living. The most important factor when selecting a filter is the merv rating and I have always told my customers the most ideal MERV rating for any high or low efficiency furnace is an 8. After testing thousands of furnaces and AC I have found that filters above a merv 8 rating cause high static pressure issues and therefore loss of efficiency and greater strain on the blower. Filters have one job and that is to protect the furnace blower / heat exchanger / evaporator coil from debris. The finer the debris that the filter is able to capture, the more restrictive the filter is.

@@vinzillabeats I agree that MERV 16 is probably overkill. But I disagree that the only job of filters should be to protect the equipment. I have allergies and have found less dust in the house with good filters. The manufacturers wouldn't sell them if they hadn't tested it. But they don't test off brand filters and my recommendation is if you have a higher end filter, buy the replacement from Lennox or Carrier or whoever made your equipment.

By all means if it is catching more dust, it will plug quicker and cause even higher static issues. I understand where you are coming from but would advise using a merv 8 and installing an air purification system.

Install a ducted air purification device before installing anything above a merv 8 if your health is your concern. If filters can capture micro particles then you can only imagine how inefficiently they move air.

This is why you do NOT take advice from someone who has NO clue what they are talking about!!!! First, the difference in the filters he held up had ZERO to do with brand, but ALL to do with the MERV rating. On buying the MERV 16 filter, 99% of the time it is going to cause you more harm than if you had no filter. An air filter was NEVER supposed to filter out the items he states are "floating around" in your home. An air filter is there to protect the equipment from getting dirty so it can perform at or near day one efficiency/effectiveness. That's it, nothing else. The filter mfrs came along and "sold" a filter on catching smaller and smaller particles WITHOUT any regard to the impact on the equipment. The number of blower motors that "adjust their airflow based on static" is increasing, but it is NOT the majority of the equipment yet. Even so, there is a maximum static pressure that equipment is designed to operate at. Once you exceed that, and his MERV 16 filter does or comes close brand new out of the box, you will end up causing that variable ECM blower motor to fail. That cost to replace that motor, if not under warranty will knock you over when you see the price!!! The best thing to do is listen to a KNOWLEDGEABLE service technician. If you do not believe me, do your own research. Right on your equipment will be a design static number, usually .5"WC. The difference in thickness of the filters, 1", 2" or 4" is only the surface area that can catch particles and the more surface area the longer it can go between changes. The "holes" through the pleats id the MERV ratings basis. So the smaller the particle the filter claims to catch, the smaller the hole and less airflow. Less airflow leads to equipment failure due to constantly being at or above the operating conditions the system was meant to be operating at. www.airfilterusa.com/resource-center/air-filter-pressure-drop-faq hvacrschool.com/air-filter-static-pressure-drop/ filterking.com/hvac-filters/merv-16-air-filter-review hvac-talk.com/vbb/threads/2215587-MERV-Filter-and-Pressure-Drops

@@jrsmyth9761 I'm sorry you're angry about the video. But I don't think you actually watched it. Counterintuitively, the filter with the lower MERV rating had higher static pressure. That's because to save cost it has much less surface area. Not all filters of the same MERV rating have the same airflow if the surface area of the media is different. If you are following the trade, you'll see ECM motors from certain brands are failing left and right, often on systems with a basic MERV 1 filter. It's usually because of cheap parts, not the particular filter used. My furnace is almost 12 years old and still on its original motor. MERV 16 filters have been in use the whole time. I change it about this time every year. I feel this 5 inch setup is a better option for most because the vast majority of people do not change a 1 inch filter every three months.

@@BensEcoAdvntr I would never recommend anything above a MERV 11 as most equipment was never intended for anything above that. Recommending anything more is a disservice as there are other factors in the system that doing so may be detrimental to the expensive equipment. Every centers around a proper delta T with the heat exchanger and safety of those in the house. The higher the MERV rating the more likely that one will just increase air leakage around the filter. ECM motors are not a longevity product in general.

@@BensEcoAdvntr I watched the video. I follow the trade, for 25 years I have been in the trade. NO!!!! A MERV 16 filter is NEVER the best option for the majority of systems and they are only okay if the system was designed around them. You did NOT show 2 MERV 16 filters for comparison, but a 16 and an 8 or 10. Again, like comparing a Honda and a Mercedes. Both are cars, but that is about it. The 1" filter is the same MERV rating as the 4", but it has more surface area to allow it to POSSIBLY last longer between changes. While you may be minimally correct in the cheaper parts as being the cause of ECM failures, static pressure is still #1 in their demise. This is easily proven by dissecting and investigating motor failures. In the evolution of the ECM, the mfr made them non serviceable from Gen 1 to now because the failure was easily found and repaired for under $2 in parts!!! That part was like a fuse, it blew with the repeated high static pressure of poorly designed duct work. A PSC motor could not care less about poor duct work and will run until the bearings fail. It is great you have had no issues with your system, but to recommend the average home use a MERV 16 filter is irresponsible and overkill!!!!

@@jrsmyth9761 I may not have made myself clear in the video as I have information that viewers may not. I'm not saying everyone should go out and buy a MERV 16 filter. The point of this was that at the same MERV value, cheaper filters have less surface area. Less surface area = higher static pressure = more wear on the system. I agree that high static is bad, that's what I'm trying to show

MERV rating is independent of brand. Bit of a pointless video, i get your argument but if you do not understand why what filter does over another, you are just going to buy some overpriced junk. every filter has its use, you should ABSOLUTE use cheep filters, especially the reusable blue ones. SUPPER CHEEP SUPPER HIGH FLOW, unless your HVAC system calls for a filter like what you have, you are WRONG. Static pressure is a HUGE SWAG. Love the shirt btw. you should be changing your filter ONCE A MONTH, not once a year. the reason your energy use is HIGHER is not the quality of air but how long the system needs to run to cool or heat the house. you can spend $50 for a set of reusable filters, clean them once per month for free, and use a HOME air filter system in high traffic areas. your energy use would be 30% lower guaranteed. NEVER use a HVAC system to "CLEAN" the air. The fact you pay almost $200 bucks for clean air a month (energy loss plus filtration is INSANELY DUMB. the energy use for a house air filter is about $2 a month and you would spend a LOT LESS with reusable filters. I have been doing HVAC coil cleaning for a long time and the only coils that suffer are those with bad drains with no traps. or no filtration at all or too high a filtration to start with. Want clean air, have your ducts cleaned once every 3 years. that and filters at all the supplies vs just one at the unit.
