In-depth Review of Honeywell HPA300 Air Purifier:
Honeywell HPA300 is one of the top-selling air purifier models from Honeywell. Here are the top features:
Powerful True HEPA Filtrations
The Honeywell HPA300 features 3 True HEPA filters as the core particle filters. True HEPA filters can capture 99.97% of microscopic particles, which are 0.3 microns or larger. Common allergens such as pollen, mold spores, smoke particles, and bacteria fall into this particle size category.
So, if you place the air purifier properly into your room, it will eventually catch almost every particle of pollutants. Depend on the usage and indoor air quality, the filters last up to 12 months on average. Also, it has a filter replacement indicator light, which will notify you when it is time to change the filters.
Filter replacement is also easy. Open the front grill and replace the filters. After installing the new filters, reset the filter indicator by pressing the corresponding filter-reset button for 2 seconds.
Honeywell HPA300 also has an activated carbon pre-filter to trap larger pollutants and adsorbing light odors. They include lint, pet dander, fibers, dust, and pet fur. By doing so, it protects the HEPA filter from being clogged up.
Besides capturing the large particles, it also captures odors and VOCs. However, this type of activated carbon filter is less effective than the granular or pelletized activated carbon filters. Don’t select the model if you need some active odor control in your room.
What you need to know is that the pre-filter has a life span of 3 months. To know it’s time to replace the filter, check the filter check indicator.
Four Level Fan Speeds
The Honeywell HPA300 has a powerful motor that consumes 100 watts of energy on the top fan speed. It has four cleaning levels, namely Germ, Allergen, General Clean, and Turbo.
Instead of labeling slow, medium, high, and turbo, this type of label will guide you when you are a bit confused about which fan speed is necessary. It is helpful because the air purifier has no air quality sensor to adjust the fan speed automatically.
You can select the general clean level, ideal for everyday air cleaning. The manufacturer recommends running this feature when away from home. During the allergen season, leave your air purifier on Germ or Allergen settings.
Lastly, we have the Turbo cleaning function. This powerful cleaning function helps to fast-track the removal of airborne pollutants.
On the Turbo mode, it delivers 300 cubic feet of clean air per minute. You will get five air changes per hour in a 450 square feet room and 8 air changes per hour in a 280 square feet room. So, when the pollution level goes high, just set it to Turbo mode and it will clean the air a lot faster.
Honeywell HPA300 also features a timer, where you can run the air purifier for 2, 4, or 8 hours. The dimmer feature will be helpful for a peaceful sleep at night.
However, the purifier has all essential features, it lacks a child/pet lock feature and remote control option, which would be useful for many.
Noise Level and Certifications
Honeywell HPA300 is not a quieter air purifier. As it’s a powerful 100 watt and 300 cfm air purifier, the maximum noise level is around 63 decibels, slightly higher than an air conditioner (60 dB). At the lowest fan speed, it’s quiet but the efficiency will lower.
Despite the high noise level, the air purifier is Energy Star certified. This is good news as you can run the purifier day and night without worry about power consumption or high energy bills.
In addition to the Energy Star certification, the purifier is also certified by the California Air Resources Board. This means the purifier does not release ozone emissions into the air. As such, the purifier is suitable for everyone.
