I need Merv 10 not 11. Would this create a problem with my furnace, and the air movement through the filter.

It should not cause a problem with the furnace, MERV 11 is a higher rating for trapping particulates. See this site http://www.filters4life.com/What-is-MERV-rating-s/4961.htm among others for a better idea.

I have read one study and several articles with no indication this would cause an issue. The difference between 10 and 11 is very small.

I am unable to answer your question specifically. My apologies. I purchased the 259112-102 filters to replace the original filter that came with the installation of our HVAC system in our chapel. The 259112-102 is working well at this point. The filter media seemed a bit thinner the the original, but again, it is doing its job just fine.

Based on my experience, no. I just moved to a house w central air and gave away my window unit. It worked wonderfully and the filter seemed to clean better than past filters I used. If you find your unit works harder with this filter, I doubt it's caused by the filter. Good luck!

I have had no problems with the filter causing much airflow resistance. At the recommendation of the furnace installer, I changed the filter every 6 months but checked it about every 3 months. I ordered replacement filters on line. In the package with the filters the manufacturer recommends changing it annually or oftener if there is a heavier dust loading on the filter.

I bought this carbon filter ... the filter itself works great! However, you may not get a 4" fan to move enough air. Usually, a 4" will be in the 200cfm range +/_ 50cfm. I use a 400cfm 6" fan with a reducer and plan to upgrade the filter into a 6" for greater airflow. If it is an affordability issue, this will make do; for quality, go 6". The variables I don't have are climate conditions and lighting equipment.

3. :-). It's got something to do with the density of the filter. The higher the number the more tiny the particles it can trap. However, this also cuts down on airflow and will cause your system to need to run harder or longer, which will raise your energy bills. My research into the matter suggested 11 or higher is for commercial/industrial needs. But 8 was deemed efficient enough / recommended for residential purposes. I hope that helps. Dontcha hate it when you ask a question and someone responds "Google it"?

I am not familiar with your particular furnace but I wouldn't think a filter of this type would cause any overheating.

Look for same MERV (Minimum Efficiency Rating Value) ratings. Regardless of capacity claims, this is an industry standard rating system that allows you to compare filters made by different manufacturers.

Hello, Our Nordic Pure Filters can be placed inside the return grill for your system. I would check the amount of CFM's that your system is running at before going with a MERV 13 filter. But these filters will work with your central air system in the return grill.

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.

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.

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.Sincerely,Bill Bochynski626-524-4392

I would say yes you can. As long as you use it the same way as your furnace use's any air filter. it just replaces the air filter that all furnaces need.

Well, I haven't looked for actual test results for proof, but from the packaging on mine: "This filter's performance has been rated MERV 8 based on the minimum efficiency observed during the industry standard ASHRAE #52.2 test. The test is a determination of the filter's ability to trap particles in the air we breathe. These particles range in size from .3-10 microns in diameter. Residential filters typically are rated in the range of MERV 1-10. Higher ratings indicate more efficient filters."

Definately not. I have had 4 units for over a year and a half with no issues. We even had a fire and I changed the filters right away and everything worked fine.

Yes, this filter has very low air resistance so it will work well on an older unit.
