OION Technologies B-1000
Score: 73/100
Freeze2trim Plug-In Air Purifier
Score: 67/100Rankings
The OION B-1000 combines negative ionization, UV-C, and a night light in a compact unit certified by EPA and CARB, drawing only 7.5 W. Its modest CADR of 30 CFM and coverage under 100 ft² limit its suitability for larger rooms. It is best for very small personal spaces where low energy use and certification are priorities.
Freeze2trim's Ion Pure Plug-In Air Purifier is a compact, filter-less unit that uses negative ion technology to reduce allergens and odors in rooms up to about 32 sq ft while consuming only 2.5 W. Its limited coverage and lack of HEPA filtration restrict its use to small spaces, though its certifications and quiet operation are positives. Best for small-room, low-maintenance applications.

Professional reviewers acknowledge the B-1000's ultra-low power draw and certification status, but they overwhelmingly criticize its limited coverage, low air-change rate, and overall weak purification capability, recommending other OION models instead.
Consumers note the quiet operation and permanent collector convenience, but the limited coverage and modest performance receive mixed reactions.
“the easy-access aluminum collector rod that requires wiping rather than replacement”
“the device produces observable air circulation at both low and high settings and includes a separate UV light control”
Professional coverage of the Freeze2trim Ion Pure is minimal; the only notable mention is a brief YouTube review by Top10Reviews that provides a long-term user perspective but lacks detailed analysis or ratings. No major editorial reviews from outlets such as Wirecutter or Consumer Reports were found.
Pros: Filterless design eliminates the need for regular filter replacements, reducing maintenance effort.; Quiet, silent operation makes it suitable for bedrooms and bathrooms without disturbance.; Compact plug-in form factor fits easily into small spaces like kitchen countertops.; Low power consumption of approximately 2.5 W helps keep electricity costs minimal.; Effective ion generation provides basic odor and allergen reduction for areas up to 32 sq ft. Cons: Coverage limited to roughly 32 sq ft, making it unsuitable for larger living areas.; Lacks HEPA or carbon filtration, which may reduce effectiveness against fine particulates.; No disclosed ion output rate or noise level, leaving performance details unclear.; Reliance solely on ion technology may be less effective for heavy smoke or pollen removal.; Absence of a replaceable filter means users cannot upgrade filtration capability.
