## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    A good OEM replacement filter for TRANE A/C Heat Pump Unit
  

*by T***6 on Reviewed in the United States on May 31, 2014*

I have a TRANE Dual Compressor 5 ton/2.3 ton variable speed A/C heat pump system that uses these filters.I have looked all over for these filters, and very few local A/C vendors carry them, and none of the big box stores carry them at all.  Also, the dedicated A/C companies that have them locally want an arm and a leg for them.The last time I purchased them online (possibly from this same company), I got a 3 pack of filters for only a few dollars more than this 2 pack that I just received.  They appear to be the same filter, and fit my unit just fine.Living here in Fl, we run the AC quite a bit, so these filters last about 4 months before I change them out (about 60 Hours of running time on my unit).Overall a decent value, however, I still think they are way overpriced for what they are...  which is some stamped cardboard with a piece of thin coffee filter like filter material inserted into it.I'll never buy another AC unit with a proprietary filter requirement again... lesson learned!

### ⭐⭐⭐ 







  
  
    They work but flimsy.
  

*by S***G on Reviewed in the United States on October 4, 2017*

The price is good but these are much more flimsy than the previous filters that I purchased (I think from this vendor, but I am not positive...they look exactly the same).  The filters provided by Trane seemed to be of higher quality, but if air does not get past these then they will be fine with me.

### ⭐⭐⭐⭐⭐ 







  
  
    PERFECT fit perfect price
  

*by R***Y on Reviewed in the United States on December 22, 2013*

First off, this item shipped very fast and for free!  They are the perfect size for my air handler unit.  I have central AC and heating and change my filter every heating/cooling season.  The costs can add up quickly, but with this option, it is manageable. I am very happy and will definitely order these again when the time comes.
