I’m approaching a year in March since I purchased my TP09, I leave it on auto 24/7, so I bought a replacement filter even though I did not get a warning yet that it needs to be changed, but I have pets, live in Florida and there’s always a lot of dust around since I’m close to construction areas, and my boyfriend’s allergies were acting up when he was at my place. I went to remove the old filter and it looks BRAND NEW. Not one speck of dust after a year of use, sparkling white as if I just unboxed it. Is my TP09 just blowing air this whole time and not actually filtering anything? Looks like I’ve had a defective unit all along which explains why I have not seen any improvements in air quality. What can I do? How can I test it? I leave it in auto mode all the time.
