Honeywell HPA100 Vs Hathaspace HSP001 – Comparison

For today’s comparison, I have picked two not-so-attractive and good-looking fellas amongst air purifiers, but, for sure, very popular amongst users.

Coming from a very popular American brand, Honeywell HPA100 is an air purifier that fits in a broad set product portfolio of a multinational corporation. Hathaspace HSP001, on the other side, is a pretty young air purifiers brand that is only focused on producing this type of air improvement appliance. 

Hathaspace HSP001 Vs Honeywell HPA100 Air Purifiers - Comparison

If you need an air purifier that can cover up to 350 sq. ft., then Hathaspace HSP001 could be your choice. But, if it’s a smaller room size that you need to clean, like 155 sq. ft., then Honeywell HPA100 is just the one for you. Don’t be fooled by the room coverage, for there are plenty of other factors that can impact the performance of an air purifier, in general. 

Right from the star, you can notice a bit outdated appearance, as given in these rectangularly shaped air purifiers. Even though plastics are not much of quality, honestly, there is nothing to complain about. For this price and purpose, I think it’s more than satisfying. 

If the color of the appliance matters to you, you should know that the Hathaspace air purifier can be found solely in white, while Honeywell in both white and black color versions

I bet you are full of questions or even doubts regarding both of these air purifiers otherwise you wouldn’t be here. Am I right? In that case, keep reading and see what I have prepared for you.

Honeywell and Hathaspace Features

When it comes to having advanced features, these two air purifiers are pretty much ready to stand up against each other. Although, Hathaspace does have slightly more interesting features to offer, contrary to Honeywell.

The one thing that caught my attention and came as quite an unpleasant surprise is the missing Filter Reset Indicator, in the Hathaspace air purifier. This means that, no matter how good this device is, you will still need to monitor the filter replacement time. It can be quite tricky to do so, especially if you’re constantly on the go. 

On the other side, features like Air Quality Sensor, Auto Mode, and Air Quality Indicator are only present in the Hathaspace HSP001 air purifier.

Air Quality Sensor and Indicator

As I already said, this is one of the features that only Hathaspace HSP001 has. This sensor is used to measure up the level of dust particles in real-time. With the use of an Air Quality Sensor, the total amount of dust particles gets to be shown on the display via Air Quality Indicator. Depending on the pollution level, the Indicator will light up in various colors. 

You just got to love air purifiers with this feature because it gives you instant feedback on the air quality and how various allergens or motions affect that quality.

Auto Mode

Another feature that accompanies the Air Quality Sensor is the Auto Mode, and Honeywell HPA100 comes without it. At the same time, Hathaspace HSP001 has these two functions combined in the same mission. That means that, while on Auto Mode, the motor will be switching gears depending on the real-time air quality.

The relevance of this feature lies in the fact that you can leave the appliance running even if you’re not in the room, and you can be assured that the air quality will be under control. The efficiency and reliability are what make the Auto Mode and Smart Sensor a winning combination. 

Remote Controller

The Remote Controller feature is only available at Hathaspace HSP001, contrary to its opponent Honeywell HPS100.

Usually, the Remote Controller is a pretty handy feature, no matter the appliance it comes with. But, I do have to point out several flaws in the case of this air purifier. For starters, the plastic quality is pretty low and you can feel it at first touch. Plus, the Controller comes without batteries, which only means another initial item to buy.

Even so, having the Remote Controller is more than a useful option. You get to control all the available options that this air purifier offers, which makes it easier for you to manage the appliance, no matter what distance you’re at. 


The Timer option is available in both air purifiers, and it can be quite a handy feature, or at least if you wish to partially program the appliance, so it fits your needs. Basically, once you set the Timer, the air purifier will run for as long as you set it up, after which it will shut down. You’re available with 2h, 4h, or 8h of Honeywell continuous purifying, whileHathaspace gives you a bit more freedom to set it between 1h and 12h of working.   

Filter Reset Indicator

This Indicator is a game-changer in this comparison since Hathaspace HSP001 comes without this option.

On the other hand, the Honeywell HPA100 owns it. Or, shall we say them? Yes, there are two Filter Reset Indicators available in this air purifier. Both of which will let you know, in due time, if and which filter needs to be replaced. There is one Filer Reset Indicator for the True HEPA filter and one for Carbon filters. If you look at the Control Panel, you’ll notice a ‘’Filter Check’’ indicator. That indicator is assigned to a True HEPA filter. Also, you will notice the ‘’Check Pre-Filter’’ indicator, which will notify you once the carbon pre-filter needs replacement. 

Sleep Mode

Even though Hathaspace HSP001 has a Sleep Mode option, as opposed to Honeywell HPA100, I wasn’t impressed at all. The reason is that, once the appliance is in Sleep Mode, it only dims the lights, but the fan speed remains on level one. This made me think that the Sleep Mode option is nothing but a farce or some kind of disguise since the air purifier does not have the appropriate speed adjusted to this Mode.  


With the almost identical, rectangular shape of both air purifiers, it is to be expected that both Hathaspace HSP001 and Honeywell HPA100 will have the same airflow. The air comes in through the frontal openings, after which it gets filtered. Once the filtration is over, the pure air gets released into the room through the upper side of the appliances. 


Of course, both air purifiers are covered with a warranty, but I have to admit the warranty that Honeywell offers is quite impressive. With Honeywell HPA100, you get a 5-year warranty, with no restrictions or conditions involved. However, I recommend you register on the manufacturer’s website as the owner of this air purifier. 

On the other hand, Hathaspace HSP001 offers a bit shorter warranty options, with 2-5 years of available coverage. Initial 2-year coverage comes if you register on the producer’s website straight upon the purchase. But if you subscribe to a filter replacement, also available online, you will get full 5-year warranty coverage.

Filtration Technology

Speaking of the Filtration Technology, the first thing I want to point out is a 2-stage filtration Honeywell HPA100, while Hathaspace HSP001 has 4+1 stages. That is the major difference regarding the filtration process between the two air purifiers. 

In the first case, the Honeywell air purifier consists of the Carbon pre-filter, and the True HEPA filter. As always, the Carbon pre-filter comes at first place, protecting the next filter in line from all the greater particles. Next comes the True HEPA filter, which will do a great job in neutralizing the odors, and get the most credit for the amazing performances that this air purifier demonstrates.

The most confusing part of this comparison turns out to be the Hathaspace filtration process. You would expect the pre-filter to come at first place, instead of the third one, which is the case with this air purifier. Since the pre-filter role is to prevent larger particles from penetrating the other filters, I just can’t seem to understand why it’s been positioned as a third filter in the system. 

Now that we’re talking about the hierarchy, let me count down the filters in the Hathaspace HSP001 air purifier, accordingly. In the first place comes the Cold Catalyst Filter, afterward come the Activated Carbon filter and the Antibacterial filter, and later on the True HEPA filter as the fourth in line. The last stage belongs to the Ionizer, which comes as an OFF option by default. Don’t be confused as I was now that I mentioned the Antibacterial filter. It is actually the pre-filter. The most useful information regarding this air purifier would be its CARB certificate, meaning it doesn’t produce illicit ozone amounts.

Another thing that caught me by surprise, only this time in a good way, was that both air purifiers have a True HEPA filter installed. Contrary, I also think that not having a pellet-based carbon filter turned out to be not so great choice for Honeywell HPA100. The reason is it failed in neutralizing the odors and lowering the overall performance of the appliance. 

How To Replace Filter On Both These Devices?

You can’t help but notice that Hathaspace has a quite bigger filter than Honeywell. Even so, they don’t last as long as Honeywell filters, and they get pretty dirty in no time while in constant use. While you get to replace Hathaspace filters every 4 to 6 months, Honeywell will demand you to do so only for the carbon filter, while True HEPA filter can last up to a full year. 

Another aggravating circumstance is that none of the filters is washable in both air purifiers. This only means you have to pay attention to your air purifier more than you feel the need. I mean, if you want to make it last and serve you well.

While Honeywell HPA100 comes with four installed speed levels, Hathaspace HSP001 has three of them plus the Sleep Mode option. Yet, even with the Sleep Mode, Hathaspace doesn’t have a fan speed paired with this option. 

Even with different speed levels, both air purifiers have demonstrated what it means to be an ear-pleasant device. Also, while working on top speeds, none of the appliances created noise that I would find annoying or worse.

Product Noise Range (dBA)
Honeywell HPA100 48.2 – 58.5 dBA
Hathaspace HSP001 41.3 – 49.3 dBA

With 48.2 dBA while running on speed one, Honeywell turned out to be louder than many other air purifiers I’ve tested. On the other hand, Hathaspace HSP001 has a better adjustment while creating only 41.3 dBA on the first speed.  

Still, if we put aside the noise level on speed one, both air purifiers are one of the rare ones that don’t make any kind of unpleasant noise. Most of the air purifiers that exist on the market are a lot noisier than they should be. 

As for this comparison, Hathaspace HSP001 demonstrated to be a lot quieter than the Honeywell HPA100. Let’s just say that Hathaspace HSP001 has joined my highest-rated bedroom air purifier list. 


In case you missed it, I will point it out one more time. There is a drastic difference in the room coverage between these two air purifiers, which means that Hathaspace covers more than twice as bigger space as Honeywell does.

Still, I conducted various tests, and they all proved one thing: if you stick to the room size as suggested by the producer, you will be more than satisfied with your air purifier.

Although Honeywell has shown pretty good results in larger rooms than 155 sq. ft., I certainly wouldn’t recommend overestimating and overusing any of these appliances. 

194 sq. ft. Room Tests

The first test I decided to do was to put both air purifiers into a 194 sq. ft. room size. As usual, both Hathaspace and Honeywell were tested separately in the same conditions, which means a full hour cleaning process while running at the top speed level, all along.

By the end of the test, Honeywell ended up with 89% cleaner air, while Hathaspace raised the bar to 94%. This performance only proves that Hathaspace HSP001 is a much better choice if you plan to use it in room sizes like this one, or even smaller ones. 

Other Tests

As I previously said, I had both air purifiers tested in various room sizes, to make sure the performance is eligible to the advertised. I had Hathaspace HSP001 tested in a 320 sq. ft. room, and the end result was more than satisfying with over 91% purified air. 

The second test I did with Honeywell HPA100 was in a 120 sq. ft. room, a bit smaller than recommended. As I expected, this air purifier managed to improve the air quality up to 93%. Amazing, right? 

Operating Costs

To begin with, I have to point out that both air purifiers have almost the same wattage. While Honeywell runs with a 50W motor, a Hathaspace does it with a 45W. As for the filter price, don’t let yourself be misled by the same price for a filter replacement. Remember that, with the Hathaspace air purifier, you will have to replace the filter three times a year, as opposed to a one-time replacement in the case of Honeywell

Product Wattage Range (W)
Honeywell HPA100 16 – 32.7W
Hathaspace HSP001 1.4 – 34.8W

This practically means that, even with identical power consumption, but much more expensive filter replacement, Hathaspace HSP001 turns out to be way more expensive in annual terms, than Honeywell HPA100.

Which One Does It Better?

Frankly said I knew it straight from the beginning that Hathaspace would have a huge advantage opposite to Honeywell. If nothing else, having greater room coverage and plenty of advanced features, really makes a huge difference. This is exactly why I declare Hathaspace as the winner of this comparison. Having an Air Quality sensor, Auto Mode, silent running, more stages of filtration, not to mention great performances, is what overruled in favor of this air purifier. 

But, to be honest with you, if you are looking for a more affordable option yet with a decent performance, Honeywell would serve you as well

When it comes to choosing the right air purifier, it ain’t never easy to make the right decision. Plenty of tiny little details can prevail, so try putting it to a table and see what works best for you.
