What an Ionic Air Purifier Does in Two Stages
Stage one is mechanical and stage two is chemical. The HEPA element measures 24 in square and is rated to catch 99.99 percent of particles at 0.3 micron. A pre-filter sits ahead of it to take the coarse load, which is what keeps the expensive element alive. Behind that pair sit two 14 in ionic oxidation generators. They produce an oxidiser plasma that works on mould spores, mildew, volatile compounds and odour, in the air and on surfaces the air reaches. A 1 HP blower with thermal overload drives the whole thing. Speed is variable from 300 to 1600 CFM, set on a recessed panel with its own hour meters. Supply is 115 VAC at 60 Hz, drawing 11.6 amps. Agriair also list a 230 volt build.
Where HEPA Filtration Fits in a Grow Room
Most rooms already move air. What most rooms do not do is clean it, and the difference shows up in the drying and packaging spaces rather than under the lights. Spores travel on dust, and dust travels on every door opening. The cabinet is portable, on four 5 in casters with rubber grip handles, and it can be ducted through a 12 in exhaust collar. Duct it out and the room goes negative, which suits a trim room. Leave it recirculating and you hold positive pressure against the corridor, which suits a clean packaging space. Agriair state it can run with people in the room. Size and weight are real considerations at 35 by 26 by 31 inches and 140 pounds. The honest limit is that this is not an odour scrubber for an exhaust line. Carbon still does that job, and this cabinet does the one carbon cannot.
