What outer filters work best? Looking at standard 12x24x1 furnace filters but what MERV level is most equivalent to what ships with this?

Dave, Don't know anything about "MERV levels" but the filter that came with my PM1200 works fine for me. I have to remove the standard filter weekly and "beat" out the dust but it is still working after 2 years.

MERV 14 for the inner filter, if Wynn filters website (an aftermarket replacement) is correct.

Yes and No.The higher the Merv rating, the more strain you will put on your furnace/blower. The more denser (Higher Merv rating) the filter, the more your blower motor will have to work. Of course, you will pull out more particles/dust/pollen etc out of the air, with a higher Merv rating. I have a variable speed blower motor/fan, so my Hvac technician can adjust my blower/fan speed. For my house, approx. 1600 sq ft, I found the Filtrate 1000 (Approx Merv rating of 11) to be ideal, with my two cats. I also buy charcoal pre filters here on Amazon and use them with my filter. They also tend to pick up a lot of stuff out of the air. I then vacume both the filter and pre filter (with a Hepa vacume cleaner) at least twice a month. I then change my furnace filter every 4 to 6 weeks-even though the filters would be good for at least 90 days. This may be considered excessive but my Hvac tech states my coils are always clean and the house is cool/warm when I want it. Next time your Hvac tech is at your house and servicing your system, ask him/her what they recommend.

Most systems use a universal size filter... If your filters measure apx 2 3\4x 9 7\8... then use should be alright

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!

Your furnace/air conditioner should have the size needed for the filter listed on the unit. If not, the size should be on the filter that is already in the unit. Whatever the size, it will be appropriate for the unit. You should not use a bigger or smaller size than the one necessary for the unit. Hope this helps.

Do a search for "Activated Carbon Range Hood Filter" on Amazon and all sizes will show up, just pick your size and place the order.

I cannot answer specifically however I can say that I could not use it on my Goodman furnace that takes a 20X25X5. The actual dimension of the filter is: 19 7/8" X 24 7/8" X 4 3/8" The length was too long for me by about 1/4" but that was enough to make it very difficult to fit.

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 apologize to you that I am unable to answer this question for you. I ordered the filters but I had someone else install it for me, so I have no idea of what you are asking me. I am so sorry! The person I had install it, had no problem at all and it works super great for me! I just cannot answer your question. I would try contacting the company and asking them.

John I would also like to know what it is. However, most of these types of filters I have seen generally have a rating of 3. It's about equivalent to the old fiber glass filters, low dust pickup but high flow. I have a 10x6x1 box (in addition to the others) in my house and it is IMPOSSIBLE to find an actual filter for it. Even the builder put in one of these types of filters. I've been here for 10 years now and haven't had any issues with my system or this type of filter for just this one.

I am getting the run-around..I have answered this question...There were four filters in the one(1) 4-pack I purchased. These were ordered as 20 x 25 x 4" and as I stated the 4" is actually 4 3/8" on the filters I received. These will not fit the filter compartment on my furnace. Please note that there are other complaints stating the same problem. Your supplier needs to accept these back in return for the ordered size. Please reply, Karen Pell

This is the top filter only. I use "Big Horn 11781 Disposable 20" Clear Plastic Dust Bags" for the bottom on my Harbor Freight Dust Collector. Hope this info helps.

They also sell those filters right here on Amazon. Just look up filter H, i believe thats the code abbreviation for this particular model. Theyre around 8 bucks, but I hear they last long!

Correct. The filter only shows 20x25,but fits the 4.5 inch furnace filter container. Ordered these and they work great.

There is no problem in using a filter bigger than what you need. Every model has a limit, as long the model is for a bigger tank than you have is OK.

There are a variety of filters available in the 4.5x20" size. All of them will work. You need to choose for yourself based on your filtering needs. I get mine here:http://123filter.com/catalog/index.php?cPath=64_32

Do a google search , I have found out they come in carbon block cyl. and 2 1-2 x 10 long , the centers about 1 in You may note the flow rate of each filter. I use my filters in tandem so its rough and then a fine. Go to Lowes or Home depot and you can compare. Note the WHKF-DWHV is 3/4 npt inlets. You may want to put a T in and run them in tandom main feeds the T and two filers at the same time ---======---- parrell NOT series Higher flow rate
