The jury is still out. Have not changed the filter again, yet. What I did notice on the installation was that Filters were a little smaller than the originals.
Some time and then a good deal should a customer have for applying direct every three mo.delvery service. Also sending customer a process delivery FYI.
Our first time purchasing these filters. I was a little skeptical using this brand but they control the dust just like the name brand. I highly recommend them.
