PRODUCT REVIEW
In-Depth U.S. Market Review
The Priestley Small Air Purifiers for Home is an entry-level contender in the highly active U.S. market for personal air quality solutions. It targets the niche of small, dedicated spaces—like a home bedroom, dorm, or office desktop —where quiet operation and compact size are prioritized over large-area filtration. Its competitive edge is the combination of a simple 3-in-1 HEPA filter system with an integrated essential oil diffuser , offering both practical air cleaning and aromatherapy.
If you are a student, remote worker, or someone suffering from mild seasonal allergies in a confined space, this is a highly attractive, budget-friendly option. Compared to expensive, large-room HEPA purifiers, you are sacrificing total air exchange rate (ACH) for near-silent operation (20dB) and space efficiency. This makes it an ideal choice for the small room air purifier segment where noise is a major concern.

1. 3-in-1 HEPA Filtration for Personal Space
The heart of this Priestley air purifier is its 3-in-1 filtration cartridge. This system is designed to provide comprehensive, multi-stage cleaning for the air in your immediate personal space. The pre-filter captures large particles like pet hair and dust, while the True HEPA component is crucial for trapping tiny allergens such as pet dander and pollen.
Finally, the activated carbon layer works to neutralize common household odors and smells, including light cooking smells or cigarette smoke that drifts into your space. For a small unit, this multi-layer approach ensures maximum effectiveness against a wide range of indoor pollutants.
2. Near-Silent Operation (20dB)
A major competitive advantage for this model is its exceptionally quiet operation, clocking in at as low as 20dB in its sleep mode. For users placing the unit on a bedside table or a small office desk, intrusive noise is the number one complaint with purifiers.
The low noise level makes this unit ideal for anyone who is sensitive to sound while sleeping or who needs deep concentration while working in their home office desktop area. The unit cleans the air without becoming a distracting presence in your small environment.
3. Essential Oil Diffuser Integration
The addition of an Essential Oil Diffuser is a clever and appealing feature for the U.S. market, which strongly embraces aromatherapy. Instead of requiring a separate device, you can add a few drops of your favorite essential oil (like lavender for sleep or peppermint for focus) to a pad within the unit.
As the air is filtered and gently circulated, it carries a subtle, clean scent into your space. This combination of clean air and aromatherapy provides a dual benefit: purifying the air of unwanted smells while also adding a pleasant, beneficial aroma, enhancing the overall small-room atmosphere.
