Top 10 best furnace air filters 2022 According to experts

Yeah, I bought the wrong ones because I’ve got bad mold sensitivities. However, I was just a little lazy about changing filters and my motor burned out. I’m one of those that take a good 20×20 Lasko fan and put one of these behind it. I filled the corners to make it a ducted fan and the sound level drops WAY down. But having the 1000 Merv 11, I’ve got loads of airflow, just crazy amounts. The fan itself wasn’t made to be ducted so the reduction in fine filtration made the airflow difference and will actually prevent this burnout from happening again, though I’ve only had it once. I think that was one of the water resistant motors which are closed. The open case motor is much cooler since air flows around the rotor and now it’s getting more air in general. So I’m not getting as good filtration, in mold and tiny stuff, but since these fans aren’t really made for pulling hard, even with my difficult to make duct, the 1000 is probably better in the long run. It blows really well on 1, so I will save some electricity and make my fans last a lot longer. These good Lasko fans aren’t cheap. I had one last 25 years but it didn’t have a filter behind it. I used it for a couple years with a filter and it seized an old dried up bearing. So I should have known that pulling air through filters with these heats things up and that will shorten the life, but it all connected when I got out my new filters and “Hey, It’s sure blowing like crazy. No wonder. I got the 1000s.” Now I remember making this decision on purpose for these very reasons, but before the motor burned out. So if there are others like me out there, I’d recommend the Merv 11, or 1000 because our fans will last longer. Maybe I just waited too long to change it. Well, that’s possible. Maybe if you’re better at changing filters, there’s no problem with the 1550, but another plus with the 1000s is that they’re cooler in the summer, blowing clean air at you from across the isle and on #1 setting. #2 is great and if I were to put the new motor into the ducted frame, the sound would pipe down. I guess it’s like everything. How much time and how good is your back to make or reuse a ducted fan? I’ll say this, If you want to make a ducted fan, get the pink or blue foam boards at Home depot. I found a purple piece of packaging foam and that cuts like butter. It’s great to work with and sound absorbing. Don’t use styrene foam, (brittle, crusty stuff). It’s hard to deal with in every way. I wish there’s someplace to buy these online. That makes it so much easier that it’s not such a dreaded task at all. Anyway, Merv 11 will allow better air flow and that might help make up somewhat for the difference in filtration but I know the 1000s are not going to ruin a Lasko in 7 years. They’ll last forever (essentially) on these Merv 11s. In this hot weather, I’m enjoying that better airflow. I also recommend the Lasko fan combo. Esp on these 1000s. They really keep the air in the house clean. I had my carpets cleaned and he said, “you’re gonna have a lot of dust here on the AC inlet louvres. Well? (he tries again.) Huh. These are completely clean. Not a speck.” He walks off mumbling “I don’t know why it’s so clean…”. It’s the Lasko/3m combination. It cleans SO MUCH air. I can go 2 years on a house filter and even then I don’t see dust, I just assume it’s there. It has to be. My inlet grates are spotless. Anyway, it really works and for so little money. I don’t even bother to tape it up. The vacuum of the fan pulls it into the fan. That’s the first thing I noticed. It barely pulled. That’s the difference between the Merv 13 and Merv 11. It is a matter of preference ultimately, so try one of each. Keep the one you don’t like because it’s a lot better than nothing. (Unless you’ve got loads of money, I guess. I’m more of a waste not want not. It’s not exactly true, but the saying has a point.) Anyway, I almost forgot. I prefer these filtretes over Filterbuy and others. They’re sturdier and I believe they filter better, the MERV ratings being equal, the 3M is better made and it filters better, though I’ll use a Filterbuy on the house system, for some reason. There’s a frame around the house filter. So sturdiness isn’t as important. These 20x20s for the Lasko fan are moved around, bumped into. They take the punishment and never get damaged. 3M really knows how to box these up, by the way. They’re glued everywhere and it’s very hard to open. Be careful.

This product was exactly what I wanted. Love it

I am really blown away at the quality of these air filters. It was easy to find when searching on Amazon and was on page 3 when I typed in air filters. Typically I go to the store and buy a cheap pack of whatever I can find. I took a chance at buying some that were still very affordable, but just a little more expensive than your cheapest ones. But I realize now the quality of these filters are completely worth a few extra dollars. The air was much much cleaner. I also run an air purifier that gives me the details of the pollutants in my air. I compared the pollutant amounts before I installed the air filter and after, the results were incredible. I had essentially no contaminants in the air. I credit this to the high quality air filter. I will definitely be purchasing more of these filters and I highly recommend anyone else who values clean, pure air to do the same

My first order came crushed which Amazon took care of with no issues. These filters are great and cause next to no restrictions with airflow. High Merv rating filters are a gimmick which cause excessive stress on the entire HVAC system. Pinch your nose and try breathing through a straw…. I recommend you get these shipped inside another Amazon box for a little extra protection.

Honestly, for the price I was expecting a flimsy filter but i just needed some on hand so I was willing to take that risk. However, I got 6 well-packaged, very nice filters. In fact, I was mentioning them to someone and they said ‘ugh i need to replace my filters but they are so expensive’. I immediately told them to look on Amazon. I never would have thought to get filters online for fear they would be damaged in the process but they are perfect!And now I can ACTUALLY change my filter every month like I’m supposed to! Adulting!

This is the size i used in 3m fliters but this filter didn’t fit the same way. Odd. Nice filter but will just stick with 3M in the future.

i installed my first new filter a few days ago and I do think that the air feels cleaner. I’ll wait a few more days to determine the dust accumulation. it’s important to know about Merv ratings. It has to do with the filtering capability of the filter. Most of the filters that you purchase in stores has a Merve rating of 6, which is a fair filter rating. These have a rating of 8, meaning that they do a much better job of capturing dirt, dust, etc. 8 is a very good filter for homes. higher ratings can be too tight of a weave and could cause issues with your AC unit because they may not allow sufficient air flow. The other big consideration is that the cost isn’t that much different that what you’d pay for one of the higher priced filters from the ‘Big Box’ stores.

Not see through which is what my HVAC guy said to look for. He said these are good filters.
