About any air filter is good, unless its alergens you're worried about them you must have a hepa. Honeywell is one of the best, and luckily most common. you can even find them at most Home depots. With Odors, however the most important thing is carbon. it absorbs the odors. Any filter that has a carbon filter in addition to the regular particulate filter will do, but be sure there is a carbon filter and be sure to change it often. you will have to check the manufacturers recommendations. (If you do before purchasing, check the price of the carbon filter, and how much it will cost for a year of filters, then you can compare to others to see which is more economical. example: if filters only cost $10.00 but you're buying them every month thats $120.00 a year. but if theres a filter thats 25.00 and you're only changing it every three months, its $100.00 a year. you're saving $20.00 overall. $20.00 doesn't seem like a lot, but is if you are struggling. the $25.00 filter is $2.40 a week. Most of us can afford to stick that in a jar. There are a lot of desk filters that you can use that will do the job, if odor is the issue, and they are less expensive than floor models. Check online, but keep in mind, the carbon part of the filter is what is most important for odors. PS don't forget the fuzzy laundry. I clean hammies once a week, but the blankets etc that go in the hammies and on the floors are twice a week. it really helps with odors. Also if someone puts a toxic bomb in the potty box and you notice it, keep a scoop handy and a special little trash can with a lid so you can make a quick scoop and diffuse the odors quickly.
