The Honeywell HPA300 is a simple air purifier intended for use in larger rooms. It might not offer the latest smart features, like built-in particle sensors, automatic fan speed adjustment, or Wi-Fi connectivity. However, It boasts a robust two-stage filtration system with three separate HEPA filters and a powerful 130-watt motor.
Our Verdict
The Honeywell HPA300 is great for pet owners. It delivers superb particle filtration performance, which is sufficient to trap smaller particles like pet dander. Its clean air delivery rate is also high enough to make it suitable for large spaces. That said, while it has an operating timer you can set to power off after two, four, or eight hours, its lack of Wi-Fi connectivity means it isn't the best option if you like to fine-tune settings and are frequently away from home. It's also quite loud, so easily startled pets might not appreciate having this air purifier run nearby.

The Honeywell HPA300 is a mediocre option for use in bedrooms. Even at its lowest power setting, it runs quite loudly, which isn't great if you want to leave it running overnight. On the upside, you can completely turn off its LED indicators, so you won't have to contend with any small lights out of the corner of your eye when trying to get some rest. It offers great overall air purification performance, too.

Compared To Other Air Purifiers
The Honeywell HPA300 is an air purifier intended for larger spaces. In broad terms, it's an unsophisticated but highly effective machine, almost a store-bought version of a Corsi-Rosenthal Box—it uses more power and makes more noise than most other comparably-sized options, lacks many of the smart features like Wi-Fi or particle sensors found on alternatives, and has three separate HEPA filters that need replacing every year, leading to high ownership costs. All of that said, it does a great job of trapping a variety of particle sizes and has a very high clean-air delivery rate.
Test Results
The user interface is pretty minimalist, though it does convey most of the relevant information regarding the air purifier's status. Indicator lights will illuminate when you need to check the pre-filter and HEPA filters. There's also a timer you can enable to have it run for two, four, or eight hours before turning off, a fan speed slider along with a separate 'Turbo' mode button, and a button to adjust the LED brightness through three levels:
- High
- Low
- Off
This air purifier has a two-stage filtration system comprised of a carbon pre-filter and three separate HEPA filters. The carbon filter is a sheet design, which has a smaller effective surface area than a comparably sized pellet-type unit and contains an insufficient amount of carbon to effectively deal with volatile organic compounds (VOCs). You should replace this carbon filter every three months; you can purchase a replacement here. A higher-performance 'A+' carbon filter is available, too, but it still contains a low amount of activated carbon. If you'd like to buy that filter, you can find it here. Meanwhile, the HEPA filters have a lifespan of 12 months. You can buy a single unit here or a three-pack of HEPA filters here.
