Air Purifier Review

Honeywell Air Purifier Review: What makes them Special?

Honeywell is a company that has always been recommended along with the top air purifier brands. Their air purifiers are usually recommended by dermatologists because of the company’s ability to understand the specific needs of their customers.

They manufacture the products not with a general solution in mind, but rather to create a particular product for a particular problem. This may include asthma, snoring, allergies, and other respiratory problems. Another thing that is good about their air purifiers is that they strive to utilize the latest technologies to ensure that their air purifiers are functioning at the maximum efficiency possible.

Honeywell has a lot of great products to choose from. Before reviewing a top product from Honeywell, it would be great to take a brief look at their model series. Two of the best model series they have released are the AirGenius Series and AllergenRemover Series.

AirGenius Series

The models under this model series are well known because of two particular features. The first feature is that it has an ifD filter that can remove up to 99.9% of toxic particles and pollutants in the air. This ifD filter stands for Intense Field Dielectric and is a type of washable filter which means that it can be reused since it is washable.

It works by charging the filter with a high voltage charge which allows the particles to be caught by the layers in the filter. The second feature is that the models have great designs that are both stylish and easy to place anywhere the user wants it to be placed. The three best models under this series include HFD300 AirGenius 3, HFD310 AirGenius 4, and HFD320 AirGenius5.

Allergen Remover Series

This model series is well known because of its great capability to clean a room, even a large one. What makes this model series great is that it can be bought at a reasonable cost while keeping the best features an air purifier must-have. It has a true HEPA filter, a good noise level, and a great design. The three best models under this series include Allergen Remover HPA100, Allergen Remover HPA200, and Allergen HPA300.

The Honeywell Allergen Remover HPA300 is often referred to as the best model among the air purifiers in the Allergen Remover Series. You can buy this air purifier for only $280. We will now take a close look at the HPA300 model.

Filtration Technique 

The Honeywell HPA3000 Air Purifier uses a true HEPA filter that has the ability to catch up to 99.97% of toxic particles and pollutants in the air even as tiny as 0.3 microns. These include bacteria, pollen, viruses, pet dander, molds, smoke, and harmful toxins from disinfectants. The filtration process follows two stages. The first stage is when the air is being sucked by the air purifier in order to filter it. The air would then go through a filter that contains activated carbon which covers the inlet.

This initial filter has the ability to remove a particular smell that would be useful for smoke and pet odor. It also has the ability to filter dust and pet hair, much like a vacuum. This particular filter of the HPA 300 can be removed to be cleaned. The second stage would be the air passing through the HEPA filter. The HEPA filter has the capability to remove 99.97% of pollutants in the air. This air purifier is so efficient that it can filter the air in the room for a maximum of five times an hour. 

Features and Design

This air purifier features three modes that have a specific use. These modes are general clean mode, germ mode, and allergen mode. The noise level of the three modes ranked from most quiet to less quiet is “allergen”, “general clean”, and “germ” mode respectively.

The germ mode is really useful during the cold season as it would help prevent the people from living inside the home to catch a cold due to viruses or bacteria. This is because the air purifier also has the ability to filter them.  An extra mode called turbo mode is also available if there is a need to make the air filtration faster which could be useful if someone is smoking inside the room or when cooking in the kitchen.

Honeywell HPA300 is a bit large with measurements of 20.08 inches wide, 22.38 inches high, and 10.38 inches deep and weighing 12 pounds. Considering the weight for its size, it is actually a light device which is a good thing especially if you have plans of moving it around the house. The design is durable and is made of metal with a great design on its edges. It also has four fan speeds you can choose from.

It also has filter indicators to alert the user if the filter needs to be changed, replaced, or washed. Since the air purifier has two filters, there are two LED indicators that will let the user know about the filter status. One is for the initial filter and one is for the second filter, which is the HEPA filter. Another great thing about his device is that the controls are actually easy to use and the settings are intuitive. The setting is also specifically designed based on particular needs.

Common Questions on Usage 

A lot of people that are using Honeywell HPA300 are often confused with the buttons “germ”, “allergen”, “turbo”, and “general clean”. In the simplest sense, they can also represent fan speed with the germ being the slowest, then general clean, then allergen and finally turbo. The allergen and turbo mode is power modes that filter the air in the room faster than normal.

Air purifiers with timers are beneficial because they can be left turned on while the user is sleeping and it would be useful for it to have the ability to shut down on its own. The Honeywell HPA300 has its own timer, which has three settings. The three timer settings in which the filter automatically turns off are for two hours, four hours, and eight hours.

One of the major reasons why there is a great demand for air purifiers is because it improves sleeping quality. Snoring is sometimes caused by allergens and pollutants in the air. When people are using air purifiers, most of them would look for a dimmer button so they can use the air purifier while sleeping. The great thing about HPA300 is that you can dim the lights on the machine to help you sleep.

The ideal size of the room that the air purifier can cover is up to 465 square feet. However, the device can also be used for even larger rooms. The 465 square feet is only based on the device’s ability to filter the room of that size for around five times in an hour under turbo mode. Following that logic, this device can purify a smaller room faster.


The Honeywell HPA300 is an air purifier that is extremely useful for filtering the air in a large room. Its turbo mode is really special because at normal room size, it could filter the room up to five cycles an hour.

If you place it in a smaller room, it would be able to cycle the air in the room even faster. This device is good for people who want clean air in their room and have normal allergies.

However, if you are specifically looking for an air purifier that specializes in eliminating bacteria and mold spores in the air, then this is not the best model for that purpose. The Honeywell HPA300 is so efficient that placing it in the middle of the room is not even necessary and it only costs $280. You can place it anywhere you want and it would still be able to filter the whole room with ease.
