Not the most fancy-looking air purifier in the market, Hamilton Beach TrueAir Compact Pet 04384 is an entry-level segment air purifier that offers just enough airflow filtration. At a very compact 8.1 inches width, 16.4 inches weight, 10.8 inches depth, and 6.3 pounds weight, Hamilton Beach TrueAir Compact Pet 04384 is no doubt the ideal size for an office desk, bedside table, or cabinet placement with limited spaces. You can even bring it around for traveling or a short staycation. The flexible design with a removable base allows the air purifier to operate in both horizontal and vertical stand without any reduction in airflow efficiency. Usability wise is very straightforward as there is only 1 top control dial knob to manage the 3 fan speeds. The front cover also snaps out easily for quick and instant filter cleaning. Other limited features available in the air purifier include a 3-stage filtration with carbon filter, timestrip cartridge (filter replacement indicator), the aforementioned 3 speed, ultra-quiet operation, and 1-year limited warranty.

While there is adequate and consistent airflow spread across its 3 fan speeds, against the big boys it is a long way behind. Together with the limited airflow delivery rate, Hamilton Beach TrueAir Compact Pet 04384 is best suited for close-range use e.g. next to your pet cribs.

What’s inside count

Hamilton Beach TrueAir Compact Pet 04384 is a 3-stage pet-oriented air purifier with additional carbon zeolite filters so many would assume it is strong in pet odors filtration. Not so much I'm afraid as the framework size and price tag means there is very limited space for a comprehensive filtration. The good news is Hamilton Beach TrueAir Compact Pet 04384 still manages to squeeze in a permanent pre-filter for dust and pet hair removal and protect the HEPA filter. The permanent HEPA grade filter will focus on removing 99% of airborne dust mite, pet dander, mold, mildew spores, and pollen. Depending on the filter frequency utilization, both pre-filter and HEPA-grade filters will need to be clean or vacuum in a period between 2 to 3 weeks to prevent the filters from being clogged with particles.

Keep it down

One of Hamilton Beach TrueAir Compact Pet 04384 strongest suit, expect low noise level throughout all speed. For nighttime operation, we would recommend choosing the lowest WhisperClean speed. For other purifying purposes, go with the higher Medium or QuickClean speed. No official figures on the power consumption but we would safely presume it is energy-efficient that tally with the low airflow delivery speed.
