If it's anything like the babies i've had ONA may cover a little but if anyone gets close they're going to know what's up..... You dont need to spend a ton of money, but in my nonbiased opinion, you need to find the cheapest (fish tank) carbon and go to office depot and they have 2 sizes of pencil holders 2 -5 bucks a piece, not positive...and an old pantyhoe (singular form? haha) there's a diy for it here, but carbon is the absolute best bang for your buck when it comes to odor neutralization. You cannot beat it! ONA helps, but mainly is a cover up and works good with other stuff. Ozone is good if you have somewhere to dump the air away from living things. but carbon is the best, cheap, safe, and it works wonders. lasts up to 18 months... it will get black stuff all over if you aren't careful, but that washes off with water. Just had a redbull and wanted to give you my thoughts!! goodluck!
