ARe the Merv 11 and Merv 12 interchangeable? My new furnace came with the Merv 11. What's the difference/

I don't know all the technical info but if you search on your computer with merve 11 it will bring up all the info you need.

Merv 12 and Merv 11 is just the rating on the furnace filter. The higher the number, the more particles the filter will take out of the air. The problem is that if you do not replace a Merv 12 more frequently (3-6 months depending on your home's air quality) it may restrict the air flow to the furnace and can possibly damage the furnace. I usually stick with the Merv 11 because I find it is the happy medium - takes almost everything out of the air but does not restrict the air flow. Hope this helps

In general no. In order to use a Merv 12 to replace a Merv 11, you need to know if you system can handle the extra pressure drop caused by the higher efficiency Merv 12. My heat pump/ ventilation system cannot support the pressure drop of a Merv 12. Compressors operated above design limit will die sooner than normal. Consult with an above average HVAC company.

The Merv 11 was the filter that our original installer put in our system. I'm not sure of the difference between the Merv 11 and the Merv 8

To be certain, I suggest you check with the merchant. At the very least, check their return policy to ensure you can return the part in case it does not fit your furnace.

It is both. You can switch it from one to other. Great heater. Our furnace went out in October and the two days we had to use it, it completely warmed my 1200 square foot home.

Dear D. Lester: No, no MERV rating anywhere on the item nor on the packaging/box. Said filter is a basic, fiberglass-type of filter. BTW, I purchased one case of these filters, there was suppose to be 12 in the case (case count of 12), but the box, undamaged and unopened, only had 11 filters in it. Good luck.

I'm not an authority on furnaces, but the motor I have is No ER318984-753 and it fits the Bryant 383. I bought the motor and never installed it. I replaced the furnace instead. This new, in the box motor, fan and connector are available for purchase if interested.

Hi Carol, I'm certainly not a pro. but "media" means the middle. In this case in I believe in Quality. So if you order "replacement media" you are getting equal to what you have already. Of course you can improve air quality by up grading the "Merv". This means it will filter more unwanted particles, which I did my last order and notice a huge difference. Hope this helps

Maybe an upgrade? Check the Merv specs. If that doesn't help , email Lennox. I love mine. No dust!

Only one. I bought here because I had difficulty finding the MERV 8. The MERV 12 is too restrictive for my heat pumps which hurts my efficiency.

Hello Nancy. Yes this is the correct board for your furnace. Thanks for the inquiry.

I am not sure what is the MERV rating. I only know I bought MERV 10. Is 10 rating?

My understanding is, it can replace your Lennox X6675. The only difference is MERV number. This one is MERV 12, it might be different from Lennox X6675. I feel MERV is good enough for my house, but it might be up to person from person. So no problem to replace it, depending whether you can accept MERV12. Hope it is helpful.

The MERV scale identifies the particle size that can be filtered. The higher the number, the smaller the particles that are filtered (as in, a MERV 11 filter traps smaller particles). That seems like it would be the better filter, BUT it usually isn't for a home system, because it makes the a/c and furnace work harder to pull the air through the filter. Your manual will tell you what is best for your system. I have asthma and cats but find that the MERV 8 is indeed the best one to use for my system for peak efficiency and filtration. Hope that helps!

There are several brands that can be interchanged with Lennox, but it depends on what you are looking for and what your unit requires...I bought the Lennox Merv 16 because of its high efficiency rating and durability (it lasts for months), and because it provides cleaner air for those of us who suffer from allergies. Just search for furnace filters and take it from there. Good luck.

Fred I wish I could help you. I have had my kit for 12 months now , just replaced the filter after 12 months. It was dirty but not bad. We have 2 cats and 2800 sq. feet of living space, a 22 year old standard furnace 80% eff. I am happy with the up grade. Can't really comment on Merv and strain on furnace.
