  • 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.

  • One thing to consider, during the Summer you want a freer flowing "efficient" Filter set in your HVAC system, and a slower one, also Efficient one for winter. 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 BealsPäivä 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!

One of my three units is very tricky because it was installed in such a way that the filter hast to bend considerably to fit into the slot. It usually get mangled in the process of replacing. (My units are for air conditioning only. I live in an old house with radiator heat.) Any suggestions would be most welcome. Thanks and keep up the good work!

  • 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.

  • 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

  • Glad to see the one I use near the top “BestAir 4 inch”. Note: it’s labeled Honeywell because it was designed to fit Honeywell F100/F200 media air cleaners. But it would obviously fit in any system that can accommodate the size. I don’t believe BestAir is affiliated with Honeywell in any way, at times that wasn’t exactly clear in the video.

  • 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 Selden3 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. Do generic replacement air cleaner brands work as well as the OEM brand? With Covid, interest in air cleaners has increased. Think of the impact in public places. Even my dentist’s office has one in their waiting room.

  • 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!

    2funion2funion4 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!

I immediately thought of you because I wondered if the price hike was actually worth it vs having several cheaper ones laying around vehicles and multiple first aid kits. Any way you can test commonly available tourniquets (Amazon)? You could quite literally save a life.

  • 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?

  • 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.

    • 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.

  • Great testing! You're the man! But MERV8? They let all kinds of really small particles through which is tough if you have asthma or dust allergies, like my wife does. I put 2" thick Nordic Pure MERV 12s on my furnace. $115 for 12. I once custom ordered their MERV14s, but they don't last too long on my relatively new 96% efficient Amana furnace before the DC variable speed fan motor starts to overheat as the filter gets clogged and shuts down. Seems to work OK with the MERV12s. I also found it's IMPOSSIBLE to find any neutral testing like you do on such a wide variety of things. Keep it up and may God bless you!

  • Having had to clean hvac coils although a weaker more flowing filter is cheaper and moves more air the problem is that the coils get dirty very fast and then no longer cool as well raising the electrical bill because it has to run longer. In the long run a better filter saves money because it keeps the coils clean and then you don't have to pay an h ac guy to come and clean it.

  • The permanent Air-Care "washable" electrostatic filter, works by airflow generating a static charge between the layers, much like an electro-static precipitator. Just dumping the flour on top and then starting airflow did not give the airflow any time to generate the static charge and thus the initial puff. Maybe all testing should have been run with airflow going prior to dumping the flour for more realistic tests.

  • Since a lot of home owners extend the life of their furnace filters by vacuuming them once in a while , I like to see you test a new filter , then dirty it up and retest it after vacuuming it . Do that on three types of filters , a cheap , then a moderate cost , and then an expensive filter .

    • @Project Farm I'm presently using a 3M merv 13 with 46 pleats in a gas Amana 95% efficient single speed fan . My concern is how much I'm impending the fan . My filter was new for last winter , and is still in use this winter . It started out as a bright white filter and is now light grey .

  • I hope your making good money from FIworld. You do the most sensible testing at your cost. Maybe you could do a video on Texas politics? Wealthier Texans: "I want my freedoms". I want guns, low taxes and the Federal government out of my life, and voting interference for the poor. When their stupid Republican freedom laws finally hit them all. They want the Feds to bail them out. Stop voting for morons for federal office and I'd be happy to send my tax dollars to you. Sorry - I didn't mean to get political on your channel. Hypocrisy drives me nuts.

  • Could you do a video on clamps? There are so many out there in so many styles. Would be great if you could look at various types of spring clamps, bar clamps, C-clamps, etc and determine things like squeeze force, damage to surfaces, and how well they can stay in place when they get knocked around. Would love to know which styles work well, and which brand is best in each style

  • I love your videos. You do a spectacular job doing thorough testing and comparisons of products. I watch your videos as they come out but I often find myself rewatching old videos when I am in the market for new products. I thought of an interesting video idea. It would be really cool to do an "Amazon Showdown". Take winning items from previous showdowns, and compare them to the cheapest (or best rated?) Amazon competitor available. For instance I recently bought some Flap discs on Amazon, they worked just as well as Diablo's, and were 93 cents per each. It would be interesting to see if Amazon can beat some of your other test winners.
