Airmega 50

See the AutoModerator comment. Air purifiers aren't good at reducing visible dust as it's large and heavy compared to "invisible" pollutants like PM10, PM2.5 and PM0.1. Take brand coverage ratings with a grain of salt. 1 Air Change per Hour (ACH) is far too low. But in any case, I would go by Clean

Yeah, the room measurements are exaggerated. Blueair purifiers are certified to produce extremely low levels of ozone via the Intertek "Zero Ozone" program. The ozone concentration limit is ≤0.005 ppm or ≤5 ppb. But it is possible Blueair units could alter existing air chemistry otherwise; don't buy

I tried leaving a comment before, but it wasn't showing under this post. Trying again... So most common air purifier brands have very little activated carbon or other sorbent media for smoke gases/vapors/odors. The USA & Canada have several choices of brands. I have no idea what's available in Spain

For a 500 sq. ft. studio, the AHAM 2/3 rule stipulates you need minimum Clean Air Delivery Rates (CADRs) of 334 CFM. AHAM 2/3 rule is mentioned the AutoModerator comment. The Medify Air MA-25 has a top Smoke CADR of 110 CFM. You need three of these units running on the highest airflow speed/setting

We generally recommend units with a separate permanent pre-filter instead. This is easier to clean than the integrated pre-filter found on the Airmega 50. An example of a purifier with a separate permanent pre-filter would be the Coway Airmega 150 or Levoit Vital 200S. But yes, on the highest airflo
