Product review (5 stars): Great deal on Aprilaire air filter medias / I highly recommend
I bought a package of three of these Aprilaire 5000 filter media's.  For the price delivered, vs the price I have to pay here at the local heating company, plus State Sales Tax, I have spaced approximately $48, and that does not include the amount of fuel cost and aggravation in driving to go and pick them up.  They appear to be original equipment parts for the Aprilaire 5000.  I put one in my unit and it fit perfectly and is doing a super job cleaning the air for me.  Being retired and on a limited income, having the extra $50 in my pocket, especially, if you change these every x6 Months, is a major help.  Like getting one for free.  I think this is a great deal at a reasonable price.
