Blue Pure 511i Max — US standard package
Use the same CADR particle type and units. A value without a named particle type stays separate from smoke, dust and pollen ratings.
A larger advertised room may assume fewer air changes per hour. Read the area and ACH together, and check ceiling-height assumptions.
Check the replacement model, recommended maintenance and purchase options. Filter subscriptions and specialty filters may be separate.
