Note MERV is not perfectly correlated with pressure restriction. A high-MERV filter can get lower restriction by using more pleats/filter media area. Project Farm did a video on this a few years ago and the admittedly-pricey 3M 1900 (MERV 13) out-flowed many filters with lower MERV.
Not to mention the width of your filter is very important, like stated in the video, if you want to go to the higher merv ratings. I've been going with 11 with 4" wide and I change 2x a year. I find that seems to be good price to effective filtering and not hindering the blower motor, for my setup. I do also have a hepa air filter running on medium 24/7 in my bedroom. Another consideration is does anyone have allergies in the house? I have some and that's why my setup is like this...
Ive had a couple HVAC techs tell me this, "the filters job is to protect the equipment, NOT filter air for breathing. Use a low restriction filter". Ive been using Purolator filters for a while now and have been very pleased with their construction and durability. If you have pets or allergies, use a dedicated room HEPA filter/fan and save your HVAC equipment extra stress.
As someone else mentioned, the 1900 3M Filtrete filter shown in the video actually tested out on Project Farm to have better air flow performance to any of the MERV 8 filters he tested. This was partially due to the many pleates the 3M filter contains and the correspondingly greater total surface area of the 3M 1900 filter filter. In fact, of all the filters Project Farm tested the 3M filter had the second greatest total filtering surface area, coming close to the surface area of a standard 6" filter.
This video is exactly what I needed. Like others, I had purchased a higher MERV rating thinking it would give us cleaner air. Well, it might, but they plug up after about a week to where our furnace can't keep up. Going back to the MERV 8 rating that I've been using for years. Thank you.
If you're plugging up filters anywhere near that fast maybe there are some changes you can make in our home? For example, I've always had two large dogs that create a lot of hair and dander. We also are far from hospital clean, we wear our shoes in house all the time and such and probably a third of our house is carpet. However, even with that a merve 11 would last us a few months.
I like your way of wiring the furnace in the case of a power outtage. It completely goof proofs it...and can be handled by others if you are not present....with no danger possible when the power comes back by those not sure how to work around breakers and panels. I change the filter twice a year....start of air conditioning season ...(end of May) and the start of the winter season (approx first part of November)
I use Merv 11 but after what you said I think I’ll switch to 8 . The whole allergen micro organism thing was causing me to go with a higher rating . 😂😂😂
I'd like to hear about the DIY design/construction/installation of a one-way air flow valve to place on the HVAC return intake vent (located on the wall of my dining room, near the floor). The HVAC unit is located in an unconditioned external closet on the other side of that dining room wall, so the air in that closet is very cold in winter and a cold draft flows into the dining room through the intake vent during the Off portion of each HVAC duty cycle (which is more than half the time). In other words, I want to block the back draft during the HVAC Off periods, without significantly blocking the intake air flow during the HVAC On periods. I've been experimenting with designs that use a large cardboard box taped onto the vent. A large rectangular hole is cut out from the bottom of the box. A cardboard rectangular "flap" slightly larger than the hole covers the hole while the HVAC is Off. One edge of the flap is taped to one edge of the hole, so the tape serves as a hinge and the flap swings up when the HVAC pulls air. The flap swing angle is limited to less than vertical, so gravity causes the flap to descend when the HVAC turns Off and re-cover the hole.
I installed a differential pressure gage across the filter. I let's me judge when the filter is plugged enough to require changing. Sine I use the 4 inch 'mega' filters it was very cost effective.
Never leave your filter in for 3 months. If you have a 1 inch filter use a standard pleated average 7 -8 this prevents restricting variable speed and ECM blowers . I have almost 30 years in the HVAC industry. He is correct don’t not use those allergen 1 inch filters if you need better air quality get a 4-5 inch media filter installed by your hvac service provider.
I was just going to suggest to ask your HVAC contractor what would be best for your situation. The guy that installed my current furnace (one of those lovely big builder homes) told me to use a MERV 1. We called a local HVAC company to come check the system because it just didn’t seem to be working well. They made several adjustments, did some balancing, adjusted the ac unit, and upgraded the humidifier (at our request). The other thing they suggested was to get the vents clean because new construction homes have a lot of crude in them-boy what he right!!! And he had us start using MERV8 filters. Having them come out was the best thing we did. It’s also a really good idea to make sure you have your HVAC checked regularly if you are not able to do that yourself.
Another helpful video. My Lennox furnace has issue with gas valve opening. The voltage when ignite blowing is always 26.99 Volt, bue t there is no click from the gas valve. If I press down the yellow and orange wire down and giggle them or remove and then put them back, it works. I am not qui
I've been using the same K&N washable filter for years, with no issues for the furnace. The blower fan and ducts are always clean. I use a hose to wash the filter every 2 months or so, rinse it with distilled water to remove any calcium deposits, and either let it dry in the sun or blow it dry with an electric leaf-blower.
HVAC Filter changes depends on the size, 1 Inch is usually 1-3 months depending on usage whereas 5 inch filters tend to be 6 months to a year, mine using a 5 inch i change out every 6 months.
@@ThereIsNoOtherHandleLikeMine Sure, so does mine. But how many months do those hours add up to? My thermostat goes by months though, it has a reminder for you to change the filter which goes by Months. in the case of a 20x20x5 Filter which is what mine uses they go for 6 months to a year between changes.
REALLY well done - thank you! Question: just as air filters for our vehicles are specific to the number of pleats in each (engine and/or cabin) and the critical role they play, does the same engineering apply to these filters?
I use a pair of plastic putty knives to grab on the old filter and start pulling it out. Beats having the filter rip up and having to fish out the pieces
I've been using a washable/reusable filter for 8 years. Ever try those? I honestly don't even know if they work well cause it's the first filter I ever put in. I think it was a merv 8.
I assume washable filters are MERV 1 (minimal filtering). One of the important comparisons here is the amount of time it takes to wash the filter, multiplied by the value you place on your labor time, compared to the price of a disposable filter. Another comparison is the value you place on not contributing to trash landfills.
Great video, question I'm seeing like white filler/putty" all over the furnace and vents,... what is it and what is it for, did you hack that yourself ? cheers
That's one of the products for sealing all the seams of a HVAC system. Similar purpose to using metallic tape, but often cheaper. All those seams in ductwork can add up to A LOT of leakage. I want the air to blow into the room itself, not the wall. Ditto for return lines, I want it to suck up the air from where it is supposed to, not from inside the wall.
Look at your filter. If it’s noticeably dirty after a month, change it monthly. If it looks okay, check it a month later. If it’s dirty then, change it every other month. If it still looks okay, check again a month later. With my cats, it looks dirty every other month. No one can tell you how often to change it but you.
The correct usage pattern is based on actual time of usage, such as HOURS - not days, weeks, or months. But nobody tells you how many hours a filter is expected to last. Most of the time your filter and furnace are not doing anything. That time does not count toward actual usage.
@@cedarwaxwing3509 Thank u. I was serious. That’s why I was shocked when he said furnace filter. I was worried I am missing some important filter after 15 years. I haven’t been to the attic so I thought it was there. Thank u
@@BoredThatsWhy I think it’s interesting that household heating and cooling systems don’t seem to have a standardized name, at least in casual usage. I mean, everyone knows what a “water heater” is, right? I am sure that contractors will explain that these systems are known as “HVAC” systems (I think that’s an acronym for Heating Ventilation And Cooling … I may have that wrong). But most homeowners refer to them as “the furnace” or “the air conditioner,” depending on what time of the year they are describing them. Assuming you have central air conditioning, the heating and cooling systems both use the same blower, duct work, and filter. One filter takes care of all of the airflow for both the furnace and the AC. Depending on where you live, the furnace/AC units may be located in the attic (mostly in the south), a main floor closet or mechanical room, or a basement, if you have one (The AC compressor unit will be located outside). If you don’t have a filter slot near the input for the furnace/AC - like he shows in this video - it is possible that the filter(s) are located behind the grates of the return air vents. I owned a two story home in Houston, TX in which all the furnace/AC units were in the attic and the filters were behind those return air ducts. I now live in Iowa, and that machinery is in my basement with a nice fat slot for the filter right at the furnace/AC. Have a nice weekend!
@@BoredThatsWhy You’re welcome. I was a little snarky in my initial response to you, so I thought I owed you a better response. I’ve owned homes in the north and the south and was passing on the knowledge I learned by way of experience and trial and error over the years.
I wonder if there is a small gap in your cold air return that is sucking in air creating a whistling sounds. I would turn on the furnace and then go around with my hand and/or towel seeing if I could change the whistling noise or even stop to identify the location.
Thicker filters do not decrease system lifespan or increase duct restriction meaningfully as long as you have a duct system that was built correctly. i.e. static pressure is low. Granted, usually this is not the case unfortunately. Furnace HVAC filters can of course be air purifiers. You can have activated carbon filters that will filter out even smoke and other undesirable smells. While having some good info, this video is not nuanced enough and will lead to people getting the wrong idea about certain things regarding filters. Lastly, while it seems logical that having a leak at the return from the filter slot would reduce return airflow coming from the ducts connected to the house, this is not necessarily true. Having a return leak can actually increase total airflow of the system if your return duct was not built properly resulting in high static pressure (which is usually the case).
In my case, a return leak is very undesirable, because the HVAC unit is located in an external closet entered from the condo unit's patio. The air in the HVAC closet is unconditioned, and gets very cold in winter.
Where did you and others get the idea that a block fan works harder and therefore lowers its life? A fan that has its air flow blocked draws less current.
You need 200 square inch of pleated filter for 1 ton of air conditioning a 20x20x1 pleat is 400square inch a 16x25x1 pleat is only 350 square inch not enough surface area for any system above 2 tons.
Aren't you assuming (1) all filters are 1 inch deep and (2) all pleated filters have the same number of pleats per foot? The purpose of pleats is to achieve a surface area larger than the filter's length x width. Are you actually talking about how much return air flow is needed? (The area of a cross-section of the duct.)
I feel like furnace filters are a first-world problem. One the filter medium businesses created. How long does it take ducts to get plugged with dust? 30 years? 10 years? Blower life is a push and pull between too much filter and not enough. Particulate is gonna reduce lifespan. Too much particulate filtration is going to put a heavier load on the blower. Is a ductless home a thing? Because it seems were just making things more difficult and complex than they need be. Remember, a natural gas furnace has only been mainstream for 70-ish years. Before that it was wood coal and heating oil. I just don't think the US has moved in the right direction with ducts vents furnaces and a/c units. I'd rather see radiant heating and cooling where there is minimal air movement and room temps are individually controlled. That "one thermostat to rule them all" is a broken way of heating/cooling multiple spaces.
Another helpful video. I am having issue with Lenox gas valve opening which is intermittent. The voltage at gas valve terminals is always 27 Volt when the ignite blows. But the gas valve sometimes does not open. If I press down 3 wires ( yellow, orange and brown ) and wiggle them little bit or I pull them out, then put them back in, it works. I do not know if I need to replace the gas valve which is quite expensive. I need your help. Thanks
The biggest problem we see with filters is homeowners read/are told to change them every three or six months and religiously stick to those numbers. Said homeowners will have 10 cats and four dogs. Changing your filters isn't one size fits all.
Furnace? Isn't a furnace a heater? This might confuse some viewers that don't have a furnace; the intent of the information is the same for any residential HVAC unit. I've never heard of an air handler called a furnace, but maybe it's because I've never lived where we mainly ran heat. Air filter or A/C filter might be more neutral terms. If you called it an air handler filter it would probably confuse viewers that have a furnace.

I've never heard of an air handler called a furnace, but maybe it's because I've never lived where we mainly ran heat. Air filter or A/C filter might be more neutral terms. If you called it an air handler filter it would probably confuse viewers that have a furnace.
