I use a Pur faucet filter to fill up my Brita filter. I filter the water I put in my humidifier-- which is filtered again before its release to the air.
I spent an intense amount of time cleaning the vents of my radiators (with Q-tips) instead of studying for my (extremely challenging) business law exam.
I have discovered and tested a fruit that effectively repels spiders and other creepy-crawling-critters. The fruit also happens to match the decor of my apartment. Curious?
A tale for another time.
