  • So which is the best filter you still didn’t tell me

  • What a great video. Excellent comparison of different filter media. I personally use merv 8 disposable filter , and replace it every 3 months. Keeping the ac evaporator coil is extremely important for the lifespan of the ac unit.

  • Would you consider testing in home HEPA filter systems? With Spring/allergy season coming into full swing I've found myself looking for one for my home but I find it funny all of them say "True HEPA" implying others are fake? I thought it'd be interesting if you tested a few of these "True HEPA Filters/home systems" Love the channel! Keep up the good, honest work!

  • I recommend 4" or 5" media filters on all systems. The additional surface space keeps static pressures down initially and over time, allowing for fewer changes. While they are more expensive they perform much better at capture. Lower static equals lower velocity as well. The FPM of air is vital to a filter's performance. To drop a few industry plugs, Spaceguard is a nice product, or Trion Air Bear if you're on a budget.

One thing a lot of vehicles have in them today other then the oil filter, fuel filter, engine air filter and a few others. How about testing vehicle Cabin Air filters? Would be good to know the best one to filter the air that comes into a vehicle.

  • Maybe test Mask types to best protect against covid. But also which one is most breathable too. Paper, Cloth, Activated Carbon filters etc. very interesting to see how you would approach. Caution not to say it can filter covid, but generally what filters dust and odors best but has low air restriction to make it comfortable to wear.

  • I skipped right to the charts, but I did read that you don't want to get a filter with a high MERV rating because it becomes too restrictive and causes strain to your unit, and the unit has to work harder, thereby increasing your electricity/gas costs. So just because 3M filtered it down to 0 isn't necessarily a good thing in every way. P.S. I bought a 10 pack of Rheems a couple of years ago. I think they were close to the cheapest at Home depot.

  • @Project Farm If you consider only the MERV8, 1-inch filters 3M basic filter seem to have the best filtration (1122 particle count only next to 3M Filterete 600 at 420). It has MUCH better static pressure drop under the load of .86 vs 1.31 of 3M Filterete 600, yet you keep repeating it might damage the furnace. This is confusing.

  • Really great video. I was skeptical about using flour as a test medium as I don't think it really represents the small particle size one might buy a higher MERV filter to protect against. Still you did seem to get some useful results to allow comparison between the filters. I was hoping you would show a table or chart with the conversion of the various rating scales. I have a Honeywell FPR 12 I bought at Home Depot, but I don't know what the MERV equivalent is. It was rather expensive. I got a good deal on Purolator MERV 13 filters at a local HVAC parts dealer, but I do wonder how they compare to the Honeywell FPR 12. I have allergies, so I need a high end filter. I'm going to by one of the electronic manometers and just mount it on the furnace so I can check the pressure drop across the filter. That strikes me as a much better way to decide when to replace the filter rather than just doing it by time. Lastly, if you do this again, or maybe an addendum, I'd really like to see how the K&N washable filter does. I can't find anything on their web site that says what the MERV rating is.

  • This is a great video. A few things to keep in mind when it comes to overall value. 1) Permanent electrostatic filters fall into the middle of the pack here. 2) An average 20x20 1 inch electrostatic filter can hold 141 grams of dust before it is saturated, compared to 40 grams with a 2 inch pleated filter. 3) That means in most cases the Electrostatic filter can remain in residential service for at least 3 months between changes. 4) We have serviced electrostatic filters that are still working as new after 20 years. 4) That's a cost "per change" of around $0.62 (62 cents). 5) Electrostatics produce no waste and can be recycled. I do not sell electrostatic filters, but have serviced them on commercial buildings for nearly two decades.

  • An aspect you may want to take note of to minimize the amount of particles going into chilling and furnace coils: Did you notice in the test of the blue painter's tape used to seal the seams in the air-return box. I do the same thing when placing the filters at the air-return grills so that the only air going into the ventilation system is through the filters. Sealing off the seams on the air-return grills does well to minimize the dust working their way up to the AC chilling coils. I recently checked the AC chilling coils and noticed not a speck of dust or lint on them after 18 years of service.

First of all the furnace filter only purpose is to keep the furnace and equipment clean. That furnace filter was never meant to clean the air in the home and is impossible to do so. If you look at the manufacture specifications they only allowed filter is a .99 cent spun fiberglass filter. Don’t waste your money it’s only going to damage your furnace good luck.

  • While the return boxes in my house are for 1 inch filters, I use specially adapted 4 inch filters (3 inches of the filter are narrower of both sides so they fit inside the return box) for lower air flow resistance. According to my research, and your test, these filters last longer and perform better, however my HVAC company said they are bad and can cause the blower motor to fail. Would you mind specifically addressing the issue on a video to educate home owners and HVAC companies? Hopefully it is not an issue to post the ones I use: www.airfilters.com/honeywell-20x25x5-fc40r1011-grille-filters.html

    Alex RuffellAlex Ruffell23 päivää sitten
  • I purchased a couple K&N filters a few months ago and here's something you wouldn't think about until you own one... A 20X30 filter with the aluminum frame is heavy enough to not be sucked up when the AC kicks in preventing that annoying slap and suction noise that you get from a cheap papper filter. I don't know why that isn't listed as a feature but if you've ever had a system that does that it's definitely something you'd appreciate because you no longer hear when the air kicks in, it's dead silent with a 5 & 4 ton unit. Even though it's heavy enough I also super glued some tiny magnets at 6 points on the frame (It's aluminum so it's not magnetic) and now it sticks right snug up to the top of the flute so it makes it easier when unlatching the grill. (Something manufacturers should consider adding as a feature)

  • You make comment about the blower motor becoming "overloaded" by a clogged filter. For centrifugal blowers (the type commonly used in home heating systems), the motor actually UNLOADS when the airflow is restricted, so a clogged filter will not damage the motor (put an ammeter on the blower motor to see the unloading when you block the filter). Centrifugal blowers can be overloaded by NOT using the filter the system is designed for. Motor cooling will be reduced by clogged filter somewhat, but there is so much airflow over the motor even with clogged filter that this should not be significant. What clogged filter WILL cause is furnace overheating and A/C freezing up.

  • So the higher the restriction, the harder your system works, the higher your bill becomes? But on most of these filters, the better the filtration, there tends to be higher restriction. So what filter has the best trade off? Good (not best) filtration, but good (not best) air flow? Do I rewatch or do I wait for an answer? Blah Im lazy

  • Flow rate is one of the most important aspect of a filter. If it restricts too much air, most residential HVAC units are not designed to handle the load and will prematurely wear out the fan motor.

  • I think you reversed saying small particle count and large at the aerostar test. Meaning you were calling the small particle count the large and the large the small.

  • I have a friend that does air conditioning service and installation. He told me to buy the cheap filters and spray them with Endust. Works great and catches dust like you wouldn't believe. Just be sure to change the filter once a month.

  • Great video and very helpful. I was one of the people that suggested this one. Thanks again for making it. My system takes a 16x20 like you were testing but only a 1" thick. I guess I will stick with the higher end 3M filters like the 1900 and change more often. I made a manometer to check gas pressure when I installed my furnace so maybe I can incorporate it as a way to check airflow.

  • Hey Todd, thanks for a great video as usual. How about a MERV 11-16 shootout for bigger sizes like 4/5/6 inch filters? I have a Lennox furnace with a whole-house allergy filter and MERV 11 is like $25-30 a filter, but a MERV 16 is $100+. Is there 4X the work being done? Also, my opening isn't even close to the nominal size. I'd be curious to see how liberal the manufacturers are with given sizes.

  • The only things that I have heard about restrictive filtres, is that they can be harder on the blower and harder on the compressor.

  • Just an fyi. I purchased a 20x20x4 based on yet another great review you have done. However, I discovered not all 20x20x4 filters are sized the same. The Standard size filters are 19.5x19.5x3.75 (what I have) the BestAir HW2020-8R is an Exact size at 19.75x19.75x4.25. Lesson learned. Thanks again for your hard work on the reviews.

  • Those electrostatic filters only work if they're hooked up to a power source. Otherwise it's just a lie. It seems obvious to me that the greater the filtration the more restrictive the filter will be. My problem is when I use the thicker high efficiency filters it kills the velocity of the air coming out of my vents. I have to use the basic, almost see through, easy flow filters if I want any air to reach the longest runs. Since the primary job of the furnace is to warm the air in the home this is what I need to do to get the job done.The key is to replace them very frequently. My moter and furnace have lasted over 26 years so I doubt there's damage being done to them by the light filters I use. I'm actually astounded that the motor has lasted this long.
