The HPA300 uses a dual-filtration process to remove all allergens from the air, including small pollutants as tiny as 0.3 microns.
The Honeywell HEPA air purifier is ideal for use in large rooms up to 465 sq. feet. This makes it perfect for open-plan living spaces, large bedrooms, and other large indoor spaces.
We love the quietness of the HPA300, especially when it is running at low fan speeds. Its all-black ribbed design is also a great feature.
The Honeywell HPA300 HEPA air purifier is surprisingly affordable for its large room capacity. As a result, we voted it the best value in our air purifiers for mold guide.

After purification, the air goes through two stages of filtration before being released into the room.
- Pre-filter – The pre-filter contains an activated carbon filter. It absorbs gases, VOCs, and large particles such as hair. Consider replacing it within three months.
- True HEPA filter – The pre-filter removes hair and large particles, while the genuine HEPA filters remove smaller particles such as mold, pollen, viruses, bacteria, and mold. This filter can remove allergens as well as tiny pollutants down to 0.3 microns.
The Honeywell HPA 300 can cover an area of up to 465 sq. feet. The air purifier can perform five air changes per hour in this space. Therefore, the purification process will repeat 12 times per hour.
Filter Replacement Indicators
Honeywell Hpa 300 has two led replacement indicator lights. In addition, each filter has one indicator. This is especially useful for those who forget the date of filter changes.
Large air purifiers can be noisy. Although the Honeywell Hpa 300 air purifier is large, it works more quietly than similar-sized air purifiers.
It has a smooth, low operation, primarily when operating at lower fan speeds. And because it makes no noise, it’s also easy to use at night without disturbing other users.
Honeywell Hpa 300 comes with a timer that you can set to the length of time you wish to run it, e.g., two, four, or eight hours.
Three Fan Modes
Honeywell Hpa300 has three fan modes: Allergen and General Clean, as well as germ mode.
Turbo mode maximizes the Honeywell Hpa 300 fan speed, and is best for maximum efficiency in extreme allergy situations.
Honeywell Hpa 300 air purifier is high-efficiency and will require frequent filter replacement, especially the pre-filter. This will need replacement every three months.
The HEPA filter might take longer to replace as it could last for up to a year.
Many air purifiers come with smart automatic features, and it may be a disadvantage if they do not have them.
However, it has a timer that you can manually set to different times.
Honeywell HPA300 is an air purifier that can effectively remove smoke & odors from your home’s air in addition to allergens, dust and other particulate matter.
It does not have an auto mode, however, so you will have to manually turn the unit on and off.
The HPA300 can get a little noisy when running at maximum speed, too – but it does a great job of removing allergens and dust particles.
This is also a great filter if you live in a dusty or smoky area.
