Air Purifiers

I live in an apartment in the middle of the city. My room gets dusty really easily and I have to dust everyday. I don’t have any allergies or asthma problems. My question is, is it worth investing in a good air purifier ( e.g.> 0, HEPA filtration etc, or is it good enough to buy a cheaper air purifier(0) with no HEPA filtration, just for the sake of keeping my room dust-free?

I bought an air purifier for my room because my dad chain smokes in the house. The box said its for a 16X10 room, but my room is much smaller than that. I keep it on all the time. Is it bad to have it on so much? I thought it may be due to the fact of drying out the air. I noticed my lips dry out a lot. Can it also dry out my nasal and eye areas and cause damage.

and is it dangerous to breath it?

I have a problem with pet odors and mold in my home. We have tried many different things but they do not work well. I have been looking into air purifiers and wondered if they would be effective in making the home smell good and eliminate odors and mold that cleaning cant seem to get rid of.

So I live in a quad dorm (4 people) that has a bathroom/shower inside of it. The bathroom is right by my bed :@ so it is starting to bother me. We haven’t cleaned it since we’ve gotten here (6-7 weeks, I know, disgusting), so tomorrow I am going to force all my roommates to clean it with me. Any suggestions on what to use/how to go about this the fastest/least disgusting way possible? Last time I checked my roommates cleaning supplies (that have never been used, lol), he had Lysol toilet boil cleaner, Oust Air Sanitizer, 409 all-purpose spray, and swiffer sweeper.

My mother had an ionic breeze running in the basement all night long on the highest setting. Though the basement is somewhat large, there is no air circulation down there to disperse or diffuse the ozone produced by the "air purifier" as the air conditioning is currently malfunctioning.

I was down there for approximately a half hour when my nose began to burn, and it was at this point that I immediately thought to ascertain whether or not the ionic breeze was on. Seeing that it was, I promptly returned upstairs and the pain in my nose subsided and eventually abated.

I’m asking this because I’m curious if I could, feasibly, have been inhaling unhealthy amounts of ozone - and if so, could my lungs, olfactory lobe in my brain, or any other internal organ have sustained cell damage?

We live in a cozy suburban home with two domestic short hair cats, and two dogs,(a teacup chihuahua and a beagle/hound mix). The cats are strictly indoors and the dogs only go outside to potty and for walks. We keep all of our pets clean and they are all well taken care of but the shedding and pet dander are becoming a concern of mine because they are irritating my allergies a little. We regularly vacuum but seeing as it’s too cold outside to leave the windows open to help keep the house aired out I was wondering the best way to keep the air in the house and everything in it fresh from pet dander and odors. Are there any sprays or cleaners? And would an air purifier or something like that help?
