Honeywell HPA300 Air Purifier Features

Before investing in the Honeywell HPA300 air purifier, you need to see its features. Here, we shall look at the features and their benefits.

Large capacity – 4.8 ACH

An air purifier’s capacity is determined by the ACH – Air Changes per Hour. For faster air purification jobs, the higher the ACH the better.

To understand the benefits of a high ACH air purifier, you have to understand how air purifiers work.

To remove pollutants from the air, the air purifier must pull in the air with the suction fans. It passes the air through the filters, where pollutants such as pollen, mold spores and others are captured. The cleansed air is then released into the room.

The unit continues pulling in the air, filtering it and releasing it into the room until all the air has been turned over. That is how it works.

A high ACH air purifier such as the HPA300 is going to do a faster job. It also has a space rating of 465 square feet. That is large, but just imagine being able to change the air 4.8 times in one hour, in such a large space.

As long as you do not use this air purifier in a space that is larger than 465 square feet, it is going to do a fast job of purifying the air.

It has 4 cleaning levels

This air purifier comes with true HEPA filters. The manufacturer says that it has 4 cleaning levels. These are Low, Medium, High, and Turbo.

The benefit of this is that you get superb cleaning power, where the air purifier can remove even smoke from the air.

These filters remove 99.97% of pollutants from the air. This includes smoke, dust, pet dander, pollen and dirt.

They also capture mold spores so that they do not have to spread to all parts of the house. Since the air purifier also has the Turbo Clean function, it can capture many microscopic particles, leaving your air fresh and clean even for babies.

The air purifier is also going to reduce the VOC (volatile organic compounds), formaldehyde smell and others circulating in the air.

When you keep trash in the house, it starts to stink because of the rotting peels and other biodegradable waste.

If the toilet also brings some of the stink back into the house, you will be happy that the air purifier can remove all of these odors.

These filters are washable and they can last as long as 12 months. After that, you should replace them with genuine Honeywell filters.

Design and build quality

This is a portable air purifier, and we suggest you stick to the space rating. If you need to purify air in a space bigger than that, you can get a whole house unit.

The benefit of buying a portable purifier is that you can move it from room to room. You can even take it to the garage, to the basement and to the kitchen. As long as there are plug-in sockets, you can use it anywhere.

This unit is so light in weight at 17 pounds/7.7 kg. While that might sound heavy to many people, it actually helps to keep the air purifier stable anywhere you place it. It can be hard for a kid or pet to topple it over. However, ensure you keep it in a safe position.

The size is not too big. This unit measures 9.25 x 20 x 22.25 inches. You will not need assistance to carry it from place to place.

The black color and the contours make the air purifier look very sleek. It compliments any interior décor you might have at home.
