Which portable air cleaner do I need to buy ?
#SARSCoV2
Factors: mechanism of filtration, airflow + efficiency (CADR), purchase price, replacement cost + filter life, and noise. 1/5 🧵
Air Cleaner Selection:
- Start by the area of the room to be cleaned (y axis)
- Consider cost (x axis) and noise (look at color of the dot; <55 db at highest setting is probably a good level)
- Consider multiple air cleaners to keep noise level down.
2/5 🧵
Choose only air cleaners that have mechanical filtration ( particulate filter media) with MERV 13 or higher or HEPA designation.
In graph above * means that there is an electronic piece to the filtration but it can be turned off. 3/5🧵
Be aware of false marketing:
HEPA-like
HEPA-style
99% HEPA
HEPAsilent
HEPA Ultra
Ionic HEPA
HEPAFast
HEPA Efficiency
HEPA Functions
HEPA Action
Plasma HEPA
Super HEPA
HyperHEPA
are ALL subpar versions of what constitutes a HEPA air filter.
Either HEPA or NOT HEPA. 4/5🧵
Stay away of fancy technology marketing:
Plasma wave
Fragrance Sponge
UV Light Sanitizer Eliminates
NCCO technology
Active oxygen generator
ionic purifier + composite catalyst
cold catalyst layer
negative ion generator
Bi-polar
PECO
PCO
Plasma
Cold Plasma
etc... 5/5🧵
