Surprising Kenmore VS Air Purifier Showdown… Office vs. Bedroom Use Case When we tested the Kenmore PM1005 Air Purifier, we were impressed by its 3-stage filtration, capable of handling up to 850 sq. feet with H13 True HEPA precision. Its QuietClean mode runs at just 25dB, making it a surprising quiet choice, whether for our bustling office or serene bedroom. While the H13 filter excelled in trapping particles, we noticed the 360° airflow worked wonders in larger spaces like the office, yet it still maintained a balanced clean in smaller bedrooms. The Timer function was handy for overnight use, but we wish there were more smart features. Still, for its performance and affordability, it’s a versatile purifier that meets both our office and bedroom needs without being overbearing.
