Austin Air Pre-Filter for HealthMate and HealthMate Plus Air Purifier

I RECIEVED THIS PRE-FILTER IN THE MAIL-- I LOVE MY HEALTHMATE AIR CLEANER-- BUT THIS PRE-FILTER APPEARS TO BE A CHEAP PIECE OF C---! LOOKS AS IF IT COSTS THEM ALL OF 2 BUCKS TO MANUFACTURE. I HAVE NOT EVEN TRIED TO CHANGE IT YET FOR FEAR THAT IT IS SO FLIMSY THAT IT WILL NOT FIT UP AGAINST THE CLEANER PROPERLY. FOR AN AIR CLEANER THAT COST JUST SOUTH OF $500.00 THIS IS REDICULOUS!!!!!!!!!! I AM UNIMPRESSED!!!!! . AS FAR AS AMAZON IS CONCERNED-- YOU GUYS AND GALS ARE GREAT--- QUICK DELIVERY TIME AS USUAL. BY THE WAY-- THE IMAGES OF THE 2 PRE-FILTERS SHOWN THE PICTURE IN NO WAY DEPICT WHAT I ACTUALLY RECEIVED.
