The air purifier does a prominent amount of work to reduce unpleasant odors and harmful particles from the air. It is slightly noisier than its competitors but that is because this one has a powerful fan which helps to regulate air many times during the day.

The details

The magnificent Honeywell’s HPA300 HEPA Air Purifier makes sure to keep the air clean all day long. It is ideal for extra-large rooms (465 square feet) and captures 99.97% of different pollutants that are flying in the air. It reduces allergens and other germs and offers effective air circulation.

Noise level

The noise level is not great and we were disappointed. The powerful fan does have its benefits but it also produces higher noise levels as compared to its competitors. The unit only has a turbo setting whereas there is no button for silent mode. So, these units are not ideal for your bedrooms or offices.


The HEPA filter captures almost all of the tiny allergens in the air. Whereas the activated carbon pre-filters eliminate all types of unpleasant odors from the room. TO make sure that the air remains fresh 24/7, the unit regulates the air five times per hour. We also fell in love with the levels of cleaning; germ, allergen, general clean, and turbo. If you have asthma or deal with any breathing condition which worsens during pollen season then this particular unit is perfect for you! It also has a filter change indicator, reset button, shut-off timer, and control panel dimmer to make using this unit as convenient and easy as possible.


The Pre-filter and Tue HEPA filter collaborate and remove as many unpleasant odors, gases, VOCs, mold, pet dander, viruses, and pollen from the air. In addition to this, the cleaning levels help massively to reduce airborne viruses. No matter the condition of the room, this small yet robust unit will make sure to check all nooks and corners of the room and eliminate the contaminants as best as possible.


One of the best things about this particular filter is that it cannot only remove particles as small as 0.3 microns but it can also remove particles as small as 0.005 microns.  Furthermore, these are specifically designed for larger rooms (465 square feet). This is quite astonishing because many competitors cover an area much small, irrespective of having the same features.

Final verdict

We loved the unit because it accommodated large rooms without compromise on the performance. The HEPA filter, carbon pre-filers, and cleanings levels make using the unit easy. However, the unit does make a large operational noise which many people might find irritating.
