ORIGINAL NO ADAPTER NEEDED, I THINK THE SUPPLIER DID AN EXCELLENT WORK. IN MY MODEL WITHOUT GOOLING A LOT. THERE ARE SEVERAL COMMERCIAL MARKET THAT SAY YOUR MODEL WILL FIT. Luckily I was able to find a website that explained all of this and then I had to go back to AMAZON to buy it. MY MODEL NUMBER DID NOT EXIST ON AMAZON BUT THEY SOLD THE FILTER.
