Review on Ultimate Air Quality with Lennox Healthy Climate X8788 Filter by Marc Stewart

These filters work great and are less than half the price my air conditioning service company charges for the same Lennox filter. However, if you have a Pure Air system, I would recommend spending $20 more and getting a Lennox X8795 or Lennox x8796 maintenance kit (if it fits your system). $60 separately and a titanium coded metal filter that costs $90 separately. You can replace all three components of your clean air system for $130 and still spend half what an air conditioning guy would charge you for just a filter. It is recommended that these parts be replaced annually so I would do this at least every 2 years unless you have very heavy A/C usage or are having issues with debris getting into your A/C from your attic or garage. Then yearly is best.
