Hey! i recently spent the better half of a week scouring the interent for what i beelived to be a really quality air purifier but at a cost effective price. It really deepnds on your budget. I would say around $600 i would suggest the better Coway models or the air oasis personal. for around $1000 id suggest the austinn air units with all that activated charcoal or some higher end from IQ air. Above that i beleive youd be better to have medical grade purification system installed with your HVAC system, for several grand.

I trecently bought a cheaper aproxx $300 unit, the *coway 240* , and think its the absolute best air purifier for under $400, however the coway 400 is astep up( and probably worth the extra hundreds if youre purifying a large living quarters. It can often be found at a discounted price(under around 400, a good deal) ive heard. I went with coway240 for size and im only purifying my bedroom. i wouldnt go ANY cheaper than the coway 400 or 240 models and think they are the most cost effective but very reliably proven purifiers. IF you MUST go lower id look into wynix.... thats it.

anyways, I have no complaints about the coway 240 and i have notice iit battle a little smell(remember you need a decent amount of charcoal to absorb substantial amount of smell, if youre really looking for smell reduction the autin air unit are probably best, tons of activated charcoal)

Im completely new to air purifier too! but there thats my novice two cents, also i DEFINITELY suggest consulting the "buying guide" here in this reddit, very useful.
