just a fyi for people that sell and service the Lennox pureair.. when the company i work for services these they always buy piece by piece to service...well no word from lennox but it looks like they sell a mant kit that has all pieces that will be 1/2 the cost of buying piece by piece... just a fyi as i found this on my internet playing 2day... i would have posted this for pros but dont have access..
