  • We have 2 houses. One has a central filter on the HVAC system, the other has a filter at each return register. After use experience, My thought: the best way is to use the best filter with one located at each return register, not a single central filter at the furnace. Or both if you have the means. The filters mostly protect the HVAC system, not the environment of the house.

  • Why doesn’t anyone know when airflow is restricted that makes the blower work less, it still makes the unit less efficient because it’s not flowing the correct amount of air. However, it’s easier on the blower motor and it makes it draw less amps.

  • I'd like to clear up a point about motor stress. Having a higher static pressure reduces the "stress" on the motor. In a reduced (negative) pressure the fan has less friction (fluid) and the fan spins easier. If a fan is in a vacuum, there is nothing to push so no work to do. Put your hand on the intake of a vacuum cleaner and the motor will spin faster. The motor will use less electric because it is doing less work.

  • Generally, I like your testing methodologies. Your criteria for testing for this one are atrocious. You mostly focused on airflow. Those of us with respiratory ailments care more about particle capture...and very little about airflow. I can easily replace a motor but I cannot easily replace a lung. You need to revisit your criteria and do a do-over. Total Fail IMHO !

  • Awesome video. A couple years ago I gave up on the cheap fiberglass filters due to allergies in the spring time. I went way too long between replacement due to cost for a good (merv 11) filter until I found these: www.mcmaster.com/air-filters/merv-filter-rating~11/ at about $6 per filter that is as cheap as most of the merv 8 filters you tested.

  • I liked the way you did most of the evaluation, except for simulating the dust buildup. You should've blown the "dust" into the chamber in a way that would coat the filters evenly. I'm sure you could find a way to feed a pre-measured amount into a runner of turbulent incoming air (like the intake on a carburated car feeds fuel). I can't imagine just dumping it produces repeatable results.

Need that volume and speed for the air cond. to get it up into the top areas of the home. Winter, slower is better for more even heating.

    David BealsDavid Beals4 päivää sitten
  • If you have older duct system (over 20yrs) and have not had a dedicated air cleaner system installed, you most likely, should not use high merv rating filters. Generally, older systems were not designed for the use of high merv filters. Most of the duct systems I see are poorly designed and/or too small and the use of high merv filters cause worse problems, i.e. mold or mildew inside the air handler or damage to motors due to poor airflow and, in the latter cases over amps or refrigerant flood back. I recommend you have a HVAC technician, from a accredited and trusted company, look at your system and help you decide what’s best for you. Thank you for your videos and your continued help to us all!

  • Number of pleats is meaningless; total surface area of the filtration media is where it's at. Also should be noted that the primary job of a filter is to keep your equipment clean; if you don't change your filter regularly dust will break down to smaller sizes and "squeeze through the medium anyway, and/or the filter will become so clogged the air will start to be sucked around your filter bringing the dust with it.

      Project FarmProject Farm5 päivää sitten
  • Hvac tech there isn't really any reason for anything more than a simple fiberglass filter unless you have severe allergies if changed correctly they keep the duct work and the coil clean and don't cause air restrictions causing your indoor fan motor to run harder and hotter everything your trying to catch in those other filters is just coming back into the house from outside unless you live in a hermetically sealed home there is no point in paying that extra money when it's pretty much pointless and if the merv 8 filters get built up and not changed they can cause your fan to over heat and you won't be moving enough air through the coil which results in the coil freezing stick to the fiberglass filters and change regularly and you won't have any problems

  • I would like to see tests of air cleaners, which are also expensive. The Dylos unit you used in this test would also work to measure how fast and how well various air cleaners work with a controlled release of dust in a confined space. I did that to test the Coway I eventually bought against another highly rated brand, which though more expensive did not perform nearly as well.

    P SeldenP Selden6 päivää sitten
    • @Project Farm You are welcome, sir! A follow up to such an air cleaner test could be a test for their replaceable filters. Also pricey.

  • Hi, just a question about the flour test. I was just thinking.....Is it possible that while spreading the flour on the filters there could be many spots that are kind of left open or clean allowing vast differences in the airflow? I know that testing each filter in a furnace for 3 months is not feasible and this might not even matter just looking for an opinion on this. I agree that more material and more pleats with a thicker profile give greater surface area and that was cool to see when you opened them all up. My furnace only allows 1 inch filters. bummer. Thanks for the video!

    2funion2funion7 päivää sitten
  • Problem with the 2 and 4 inch comparison is the furnace filter socket must be changed or come that way to use those. Must compare thickness to thickness which is what most of the test was! I would be interested in a comparison of 4 inch thick filters since I find many new homes use these not only for long filter use but the low pressure draw from them. I actually am going to add a home made manometer to my setup to compare new to old filter and monitor its lifespan. A brass fitting, glue, clear hose and little food colored water should do the trick!

  • In looking at the 3M Filtrete 1900 I noticed that some come with a bluetooth manometer built in to the air filter for an extra $5. The reviews on these are very mixed so I have a couple of questions. Does the sensor itself block airflow in any meaningful way and more importantly, how accurately does it reflect the state of the filter? You could use your existing test stand to do a calibration test of the smart air filters at different stages of load (filter life). Now I bet that will REALLY scare some marketing departments! As always, thanks for your hard work.

  • I own that same Chinese made manometer and a pair of Fieldpiece probes at my home to check pressure drop across filters. I also have the same 16x20x1 filter size. I am planning to have a Honeywell 4 inch merv 11 unit retrofitted at my air handler this spring. My filter is undersized for my 2.5 ton HP. I will install minimum 20x20x4, hopefully will be able to fit in a 20x25x4. Because of fpm velocity at 1000 cfm, the 1 inch pleated merv 8 filter is too high static for my 16x20x1 undersized filter. What cfm and/or fpm velocity were you pulling across those filters ? A filters sq inch surface area greatly affects static pressure.

A couple of years ago I went with MERV 11 filters and there was a difference but I am considering having my HVAC guy come out to widen the slot for two or four inch thick filters to increase efficiency and airflow. I might even go with a MERV 13. Buying filters by the case significantly reduces the cost. Thanks too for clearing up the 3M marketing plonk as well as the other one, FPR from Home Despot?

  • We had a new AC duct system put in not long ago at our house. Works great, no complaints. Checked the filter media, it was sadly the $1 one. Immediately went out and bought a Honeywell FPR 10 based on your findings 👍

  • Where did you get the 2" Honeywell bestair 2" filter? Can't find it anywhere, not even Honeywells filter site.

  • While I think your testing methods are interesting, I don’t think your they are realistic for most cases of normal use. As dumping a cup of flour on the filter would be a edge case. Normally dust particles come in at a relatively constant pace and build up over a period of time or maybe a spike of particles here and there. Would rather seen a “normal” amount of dust particles over a period of time and the efficiency of each filter over that time period. But found your results interesting and appreciate your work. Thanks for the video.

  • Thanks for this testing. I live under an airport landing and take off pattern and my filter turns grey in a week and black in three weeks. I didn't really here a recommendation on this testing for a one inch filter. I guess I'll get the one inch filter with the most square inches of material.

  • I'm only 18 years old and I normally would have no interest in air filters and other stuff on this channel, but the amount of effort you put into these tests are insane and I've watched a lot of your videos just because of how interesting your channel is

  • I am an HVAC tech and unless you get a 4-5” filter on your air handler stay with cheaper filters with a lower merve rating. If your ac is not built to handle high static pressure don’t use high dollar filters. Use a common pleated filter and change regularly

    • Also a media filter is usually blue or orange on one side and white sticky on the other. Pleated filters have a white pleated look, and have an accordion look, they are the best in when thiicker,4-5” and a lower merv rating unless you have an inverter airflow control system.

  • Yeah, we have a real problem with flour exploding in our furnace ducts. You might want to get opinions from HVAC repair people, most people don't change filter often enough & use to restrictive of a filter especially during cooling season.

  • Could you do a video testing shop dust collection systems? Or do a different style for you but make a dust collection system based on the data from your shop vac video and this one.
