This unit is excellent at taking down airborne particles such as dust, pollen, cigarette smoke, cooking odors, fireplace smoke, pet dander and mold spores.

The Honeywell uses a technical filtration technique, which means that a fan drags the particle-stuffed air directly into the device and pushes that air all the way through a True HEPA filter, successfully circulating the air in an area up to five times within an hour. Besides that, the air purifier does not release any ozone back into the room, which is good for users with more substantial breathing conditions.

Circulates air 5x per hour

The functioning of this air purifier is straightforward: a fan draws air into the purifier and by using a pre-filter that takes up odors and captures debris like dust and pet fur. The air then runs through the True HEPA filter, where then 99.97% of all the allergy-triggering particles are captured.

Activated Carbon

To counterbalance the smells successfully, the Honeywell HPA300 needs to have activated carbon. This is typically put together with a potassium iodide or zeolite in the air filter to be able to optimize the elimination of toxins.

Zeolite is a frequently used organic mineral that is made use of to absorb some gas molecules like ammonia, formaldehyde and carbon monoxide. That is the reason why activated carbon has an essential function in absorbing toxic gas molecules including tobacco smoke, smells, and mildew.

Filter Life Indicator

A digital screen will point out to you when to replace your filter. A filter light signal shows you that you should change the filter as soon as possible.

No Production of Ozone

Among the list of primary reasons why a lot of people favor the Honeywell True HEPA air purifiers are due to the fact they do not release any ozone back into the air when filtering the air; as a result, the Honeywell HPA300 Air Purifier is best suited for people with difficulty in breathing.

Honeywell HPA300: FAQ

Some consumers wonder if this specific air purifier makes the room “hotter”. As with all appliances, also this device produces warmth, even coolers (although you won’t think of that). The Honeywell HPA300 uses 130 watts of electricity which is released into the room as ambient heat, you can compare the heat to a light bulb of 130 watts when you put the air purifier on the highest setting. You will basically not notice the increase of temperature in a big room caused by the Honeywell device.

In a much smaller room, you might notice the temperature difference, but it won’t dramatically change the room temperature. Some buyers even notice the opposite, making the room much cooler instead.

People ask the question if this model comes with a filter. To answer this question, we purchased this Honeywell HPA300 from Amazon and we can confirm that this air purifier comes with two filters: The main True HEPA filter, which lasts for 1 year and the Pre-filter which is running for 3 months upon replacement.

Some people are wondering where the intake and exhausted air are located. To answer this question quickly you have to understand that the purified air blows out of this device from the top. The intake air happens on the front side of the Honeywell HPA300.

The air purifier is not designed to remove any volatile organic compounds (VOCs), it only removes dust, mold spores, pollen, pet dander and some other particles from the air into the filter. It is also perfect to eliminate smoke and smoke odors.

The Honeywell HPA300 provides a lot of airflows. When the air purifier is set on turbo mode, the device creates a lot of air, plenty to produce a breeze in a room and rotate the ceiling fan. This is how effective the Honeywell HPA300 is. Setting it at higher fan speeds produces a sound like some sort of jet engine, which is remarkably acceptable and far from bothering.

One consumer bought the Honeywell Air Purifier for her family area with an overall size of 900 sq ft. This air purifier is supposed to work at its very best inside of a room not larger than 590 sq ft.

Nevertheless, this consumer is delighted that the Honeywell HPA300 still operates effectively in a much larger room. The outcome is a remarkable reduction of dust and other particles lowering the quality of the air.

Honeywell HPA200 vs HPA300: Air Purifier Comparison

As you can notice from the earlier pointed out listing, the differences between the 3 Honeywell HPA air purifiers are somehow small. Actually, the only considerable difference is the room size coverage that each air purifier can deal with. If you are looking to purify the air in a tiny room, the Honeywell HPA100 is your ideal option. A medium size room would be perfect for the Honeywell HPA200 and for a mid-sized room up till 465 square feet, Honeywell HPA300 is the perfect pick.

We are unsure about the reason why, but both the Honeywell HPA100 and HPA200 are offered with a color option of white or black. The Honeywell HPA300 is only available in black. This seems a little strange to us because usually, a brand will restrict the color possibilities for the cheapest models, not the most expensive ones, as a way to lure you to upgrade to a more higher priced item.

Another unusual difference regarding these air purifier models is that both the Honeywell HPA100 and HPA200 offer 4 cleaning stages, while the Honeywell HPA300 only offers 3. This is yet another case where a business in most cases does the opposing strategy in order to improve product sales. No matter what, a number of cleaning stages does not make a huge difference in this case at all as the Honeywell HPA100 and 200 model only has an extra fan speed.

The company has given these cleaning stages particular labels, such as Germ, Allergen, General and Turbo, but the reality is that these labels are similar to the terms Low, Medium, High and Turbo fan speed modes.

The Competition

The competition is not just within the Honeywell brand, many air purifier manufacturers believe that the $200 segment has the most significant price point. If you are looking for a capable air purifier, you need to decide if you want to go for the Coway AP-1512HH, Blue Pure 211+ or Winix 5500-2. They are more or less better than the Honeywell HPA300, and that’s why they always stay on top of many lists of best air purifiers.


While the Honeywell HPA300 True HEPA Air Purifier comes in a little more expensive compared to other air purifiers available, it also works better compared to those lower priced models.

This air purifier does a very good job of purifying the air in your room, which is exactly why you buy this machine. We recommend that you test this purifier a room with the worst air quality, and then move on to other devices once you get an understanding of how well an air purifier works to clear the air.

The Honeywell HPA300 Air Purifier is a good air purifier if you have some serious breathing issues related to asthma, allergies, etc. The True HEPA filter of this device is extremely efficient and catches every little thing from smoke, pollen and pet dander to name some. This is one of the best air purifiers for allergy sufferers from Honeywell. Not only is Honeywell commonly ranked at the top by professionals who suggest using air purifiers, but you will see advantages to your breathing conditions in even big rooms up to 465 sq ft.

Air purifiers designed for larger areas tend to be noisy, large obstacles in a room. The HPA300 model from Honeywell is an exception to this rule, as the device has a controllable noise level.

You are able to manage the purifying settings of the air purifier as well, and on the lowest setting, it is silent enough for a peaceful midnight sleep. The Honeywell HPA300 has helpful side handles to carry the air purifier from one room to another. However, on the side note, the Honeywell HPA300 also lacks some necessary elements, such as an automatic mode and a remote control.

Overall, the Honeywell HPA300 True HEPA Air Purifier includes a True HEPA Allergen Remover filter for the greatest level of filtration to protect against allergens. A carbon pre-filter catches typical household smells, and the electronic filter sign lets you find out precisely when to change the filters.

You might stumble on numerous reviews from consumers who suffer from allergic reactions and have seen radical changes. If the Honeywell True HEPA Allergen Remover is a device that may well help you, you should consider buying this device from a reliable online store like Amazon. Have a look at the order box below to see the latest price.

Air Recommended Air Purifiers

Our Pick Perfect for bedrooms, playrooms, and living rooms, the Coway Airmega AP-1512HH is one of the best-performing, most durable, and most economical purifiers we’ve tested.

Most Popular The Levoit Core 300 air purifier has some strong suits, but in our opinion it falls short of carving out a meaningful niche for itself. Its ideal use would be in a small bedroom occupied by someone who is sensitive to noise.

Also Great With high end air cleaning performance and a whisper quiet fan, the Winix 5500-2 is the perfect combination of power and finesse. It cleared airborne particulates out of our smokey testing room faster than any other model.

Best of the Best If you have a large space you want to remove irritants from, We recommend the Airmega 400S. All of Coway air purifiers do an excellent job of attacking indoor pollutants, and we highly recommend any of them. The 400S is designed to accommodate large room sizes.
