+7 pts“The AHAM 2/3 rule stipulates you need a minimum of 140 CFM CADRs. If you're prone to wildfires, Smoke CADR needs to equal a room's area;; in that case, you'd need a min. Smoke CADR of 210 CFM. The Airmega AP-1512HH Mighty will **not** tackle VOCs, smoke odors, or visible dust. To answer your question, it does look like a good price in CAD. See the AutoModerator comment for our subreddit's resources on visible dust. There is a very tiny amount of activated carbon in the Mighty's respective filter. You need pounds of activated carbon or other sorbent media for gases/vapors/odors/VOCs. And depending on which gaseous "species" are present, you may need chemically modified (e.g., impregnated) sorbents. Heavyweight sorbent purifiers are very loud, very expensive, and clean the air more slowly than particulates-focused purifiers. Examples are Airpura and AllerAir. The "cheap" odors and VOCs option is the [Oransi TrueCarbon 150C](https://oransi.com/products/truecarbon-150c-air-purifier), which uses 3.2 lbs. of potassium permanganate (KMnO₄) impregnated activated carbon. The Mighty should be good for other particulates (e.g., smoke particles, pollen, animal dander, soot, mold spores/fragments, etc.), although it may be somewhat loud on the highest airflow speed or setting. [Infants and young children should not be exposed to overly loud air purifiers](https://www.reddit.com/r/AirPurifiers/wiki/index/how_to_choose_an_air_purifier_for_particulates/#wiki_regarding_infants_and_young_children). According to a *Pediatrics* article, USA hospital nurseries have recommended sound level limits of 50 dBA. I would recommend something like the [Coway Airmega 240](https://cowaymega.ca/products/airmega-240?variant=40263676592170) instead—if your budget allows—for particulates.”
