Top tip, dont be quiet around your sleeping baby otherwise it will be a light sleeper the rest of its life and wake up at the slightest sound.
We used to hoover around our little ones cot, she sleeps like a log now, falls asleep anywhere.
My friends daughter wakes up at the slightest noise, when we went round there the mother would have the TV volume turned off and be whispering, and all the child does is wake up screaming all the time.
As for filtratiopn cant help, I have canisters on my 180.
