Replaced dirty filters, fit perfectly
We are really happy with our filter purchase! It fit perfectly with no problems! Will buy again!!
Great filter for the money they last four 5 months and we just purchase a new one for the money instead of trying to clean it. The filter came to the house in five days

I got what I asked for in a timely manner.
