The Honeywell HPA300 is a $250 budget-friendly air purifier that can stand on the desk or floor and clean the air of unpleasant allergens. This filter is particularly good at cleaning out annoying particles that can cause allergies or stink up your house, and may make a great choice if you are buying your first air purifier or just want a purifier to help you clean out a small loft or similar space.

This model may only be large enough to handle one room, but reviews were impressed with how well it did overall.

However, some questions remain about how well the model can keep up with the ultra smart, high-powered models that are currently on the market.  So let’s take a closer look!


This Honeywell model has four fan speeds and is rated to clean up to 465 square feet of space. While it’s not packed with features, it does come with automatic shutoff sensors to save energy after the purifier has been operating for a certain amount of time. It uses a HEPA filter that will need to be replaced regularly, but which excels at removing allergens and similar small particles.


  • Affordable
  • Effective at removing dust
  • 4 Speeds


  • Not many setting or control options
  • Only fit for one average room

Top Ten Reviews

Top Ten reported that this model was one of the best at removing dust particles from all the models they tested, but that it struggles a bit with pollen and isn’t as smart as some market contenders.

“Large-room air purifiers tend to be loud, hefty eyesores. The Honeywell HPA300 is an exception, as it has a manageable noise level, convenient side handles and a low-profile design. However, this air purification system lacks some key components, such as an auto mode, sleep mode and remote control.”

Consumer Reports

Consumer Reports like the way that this model removed larger particulates from the air, and noted that changing the speeds makes a real difference when it comes to noise vs. air quality. However, they also had an issue with the high running costs and filter expenses.

“Effective at removing dust, smoke, and pollen at its lowest speed, which matters if you’ll run the unit in your bedroom at night. Especially effective at removing dust, smoke, and pollen at its highest speed, important for quickly cleaning the air in the room. Especially effective at removing smoke. Runs quietly on its lowest speed. Not especially quiet, but among the quietest air purifiers when on its highest speed. “

Amazon Users

Amazon users were big fans of both the low cost of the Honeywell HPA300 and how well the HEPA filter worked. It seems to make a great choice for allergen/asthma sufferers who are on a budget.

“This was purchased to keep the dust down in the house and it works like a champ. It also kills odors so kitchen cooking smells seem to vanish quickly. Very quiet on lower speeds and the Turbo function is great if you want to get rid of odors or smoke (kitchen smoke not cigarette so I can’t comment on that).

One GREAT feature this has is a dimmer for the lights, I also purchased a smaller version that doesn’t have the dimmer and the blue lights light up my daughters bedroom.”

Bottom Line

A great buy if you have a limited budget but need dust-clearing results. Just don’t expect it to do everything automatically. Check out additional air purifier reviews here.
