There are many reasons for wanting to buy an air purifier; maybe you have allergies, maybe you want to get rid of cigarette smoke, maybe your life has been taken over by pet dander. Breathing clean and clear air in your own home is something that everyone can find value in. Luckily Honeywell makes a number of air purifiers to choose from.
Honeywell is one of the most respected names in the industry and has the full might of the Honeywell brand to design, engineer, and support a quality air purifier for consumers. So what is special about the Honeywell HPA300? Why should you choose it over other air purifiers? I hope to answer those questions and more in this complete review of the Honeywell HPA300.

Honeywell makes a whole bunch of air purifiers in all different shapes and sizes. Some are made for larger spaces and some for smaller, some have disposable filters while others have permanent filters. The Honeywell HPA300 is the brand’s top model in its lineup of air purifiers.
The Honeywell HPA300 air purifier filters dust and pollen using two filtration stages. There is an initial activated carbon filter, sometimes called a pre-filter, and then a true HEPA filter. These two stages are able to capture up to 99.97% of air particles larger than .3 microns. A micron is incredibly small. For reference, a single red blood cell can be 5 whole microns big. That means that the Honeywell HPA300 catches particles that are more than 10 times smaller than a red blood cell. That’s amazing!
How Does The Honeywell HPA300 Work?
The first stage of filtration is the Honeywell HPA300’s pre-filter. The pre-filter is a thin black layer made of activated charcoal that covers the whole surface area of the inlet. This filtration layer serves several purposes. One thing this layer does is kill odors. Activated charcoal is a special material that is used as a filter and odor killer in all kinds of industries.
Water treatment plants use activated charcoal to filter water, some shoe insoles use activated charcoal to get rid of stinky feet, and it’s even used in the medical field. While this layer can’t kill every odor in your house it will kill most and will make really powerful odors less noticeable.
The prefilter is also important for filtering out large particles from the air. Things like pet hair and dust bunnies will first be captured by this layer while the next layer handles the finer particles. This is an important feature in extending the life of the more expensive HEPA filter. Another great feature of this layer is that it is easily cleaned or washed.
When dust builds up on this layer the filter can be vacuumed or run under the sink. This is important to make sure that your machine is always cleaning the air as best as possible and because you will save money over just throwing away dirty filters.
The second filtration step is the most important step in the overall process. After air passes through the pre-filter layer it reaches the true HEPA filter. This is the layer that catches all of the fine particles like pollen, dust, and even some bacteria. HEPA stands for High-Efficiency Particulate Air and is actually a designation by the U.S. Department of Energy. The requirement by the DOE is that it filters 99.97% of particles larger than .3 microns. You can read about HEPA filters on WebMD to learn about their benefits for people with allergies.
Air Purification isn’t the first place that HEPA filters have been used. The filter used in the Honeywell HPA300 is the same type of filter used by responders in a biological attack and it’s also used in the medical industry by doctors who deal with tuberculosis patients. The HPA300 has three of these filters to help make your air clean and crisp.

How do you use the Honeywell HPA300?
The Honeywell HPA300 has a few more features than most air purifiers and so requires a little reading to learn about its settings.
One thing that is confusing about the HPA300 is the buttons labeled “germ”, “general clean”, “allergen”, and “turbo”. These buttons don’t actually change the way it is filtering the air, they are simply speed settings with “germ” being the slowest speed and “turbo” being the highest speed. Why did they label the speeds this way? Nobody knows… A system of “low” to “high” or “1” to “4” seems like it would make more sense.
On “germ” mode the HPA300 is virtually silent. This is likely the setting you will want for sleeping or watching movies or reading. “General clean” mode is audible but only at a low level. It actually makes a nice sort of white noise that you might enjoy while sleeping or reading. The next two power levels are too loud to try and sleep with but they clean the air like a machine. On the “turbo” setting the HPA300 can cycle a room’s air 5 times an hour.
The HPA300 also has 3 timer settings. You can set the air purifier to automatically turn off after 2, 4, and 8 hours. Of course, you can also just leave it on all the time to run continuously.
I really like how the Honeywell HPA300 has a dimmer button. The dimmer button lowers the lights on the machine so that it is less distracting. Many people will want to have this air purifier running in their bedroom while they sleep or in their living room while they watch a movie, and so have less distracting lights is a good idea.
The Honeywell HPA300 also has indicator lights that come on to signal when it’s time to change the filters. Each filter even has its own light.
The manual says that the HPA300 is good for rooms up to 465 square feet, but lots of people use it in even larger spaces. 465 square feet is about a 21 x 22-foot room for reference. Even though it’s made for large spaces the HPA300 can also be used in smaller rooms and will be able to cycle the air even faster.
I really like the way the Honeywell HPA300 works compared to most other air purifiers. The HPA300 pulls in air from the front and then spits it out the top after filtering. This is great because you can have it set aside and out of the way, you can even put it up against the wall. Most air purifiers pull air from the back and spit it out the front.
This means that for most air filters you need to have them away from walls and corners so they have access to the air in the room. But who wants to have one of these things sitting in the middle of the room?
What is the cost of filters, where do I get them, and how often do they need to be changed?
There are indicator lights on the Honeywell HPA300 that tell you when it’s time to change out your filters. Usually, the schedule is to replace the pre-filter every three months and replace the HEPA filters every year. You can also extend the life of your filters by vacuuming your filters once a month or more and cleaning your prefilter.
When it comes time to change filters you, fortunately, have options. The activated charcoal pre-filter can actually be bought in large sheets which you can then cut to size using scissors. This option is super economical and leaves you with extra filters that you can swap them out when you want. You can also buy pre cut pre-filters that fit this unit specifically. This is a bit more expensive but the activated charcoal isn’t very expensive, to begin with. You can find both of these options on Amazon.
The HEPA filter cannot be washed like the prefilter can, though it can be vacuumed to help make it last longer. When it comes time to buy new ones they can be found at most retailers who sell things like this, like Walmart, Target, Staples, and Amazon. The Honeywell HPA300 air purifier filter pack value kit has an MSRP of about $80 but can be found at a better price on Amazon.
When buying your HEPA filters, remember that the HPA300 uses 3 filters. Most places sell these filters in 1, 2, and 3 packs, so make sure that the one you buy says “3-pack” on the box.
What is the warranty?
The warranty for the Honeywell HPA300 is 5 years. Honeywell is a large company and has the resources to honor its warranties.
What are the cons to owning the Honeywell HPA300?
There aren’t many downsides to the HPA300. Most people are satisfied with the build quality and the way it operates. I will say that, for the price, this air purifier seems to be missing some features that other air purifiers have, like UV light to kill germs. It’s possible that Honeywell engineers found that the UV feature doesn’t add enough benefit to be worth it.
How does it compare?
Honeywell HPA300 vs HPA200
The only difference between these two models is the size and the price. The HPA200 is made for smaller rooms and doesn’t cycle air quite as fast as the HPA300. The HPA200 is also smaller and only uses 2 HEPA filters while the HPA300 uses 3. This means that the HPA200 is cheaper to operate. If you are trying to purify the air in a large space then I recommend buying the Honeywell HPA300
Honeywell HPA300 vs Winix 5500-2
The Honeywell HPA300 and the Winix 5500-2 are pretty comparable models. Both models look similar; they are both wide and are both black. Both suck in air from the front. Both have timers and 4 speeds. Many people will like that the Winix has a remote control.
This is helpful for people who don’t want to walk over to their air purifier to adjust settings every so often. The Winix also has an “auto mode” that adjusts the fan speed based on the air quality in the room. This is a great feature for people who just want to leave their air purifier on all day. The Winix also costs about $30 more than the Honeywell.
One advantage that the Honeywell has is it’s ability to handle larger rooms. The Honeywell can handle larger rooms of 465 square feet while the Winix is only rated for 360 square feet.
The Honeywell HPA300 is great for people who want to purify the air in a large space. People with large open floor plans will like how it is able to quickly cycle through the air in a large space. Also, people who just want to tuck their air purifier away in a corner or against a wall will like the HPA300 because it sucks in air from the front and shoots the clean air out of the top.
There is no need to stick this purifier in the middle of a room! I wouldn’t recommend the Honeywell HPA300 for people with severe allergies or people trying to kill mold spores in the air since it does not have UV light. People with normal allergies or people who just want cleaner air will love the HPA300.
Where can you buy the Honeywell HPA300 and how much does it cost?
The Honeywell HPA300 can be found at most big box stores. Walmart, Target, Best Buy, and Amazon all carry the HPA300. The MSRP is about $300 but you can usually find the HPA300 on Amazon for way way less than that. You can click below to check the price now on Amazon!
