Hathaspace Smart True HEPA Air Purifier
If you are on the hunt for a true beast of an air purifier, one that can easily handle the entirety of an average size home, the Hathaspace Smart True HEPA Air Purifier is a great product to take a closer look at.
Product Highlights
Right off the bat, one of the most impressive aspects of the Hathaspace Smart True HEPA Air Purifier is that it is designed to handle up to 1,500 of space, which should be more than enough for any apartment, condo, or even for a whole house. Remember, this unit can process 1,500 square feet worth of air every single hour.
To provide you with the cleanest air possible, this particular air purifier features a full 5 stage filtration system.
The first stage is a simple washable pre-filter to capture large airborne particles; the second stage is a Polypropylene Pre-Filter for dust and hair removal; stage 3 is an H13 Medical Grade HEPA filter that has the ability to remove particles as small as 0.1 microns from the air; stage 4 features activated carbon for odor and gas removal; and finally, stage 5 is a cold catalyst filter for VOC removal.
The Hathaspace Smart True HEPA Air Purifier comes complete with a sleek touch control panel for easy use, and yes, it comes with various speed and timed settings. However, the really cool part is the air quality sensor that tells you exactly how clean the air is, and when turned onto the automatic mode, this air purifier will automatically adjusts its output based on the air quality.
What you may also appreciate about the Hathaspace Smart True HEPA Air Purifier is that it comes with a whisper quiet sleep mode, so you can breathe easy even as you sleep. On that same note, this particular model is also designed to be extremely energy efficient, up to 60% more efficient than other comparable models.
The Good
What really stands out about the Hathaspace Smart True HEPA Air Purifier is that it’s just an all around high quality air purifier, one made with durable parts, a user friendly design, and some pretty high tech functionality too. Simply put, if you need a powerful unit for a large space, this might just be it.
The Bad
One of the downfalls of the Hathaspace Smart True HEPA Air Purifier is that the innovacious-20nt filters appear to be super difficult to locate. Besides that, unless you are running this unit on the quiet sleep mode, it can be pretty noisy, especially on the higher settings.
Pros
- Easy operation
- Filter change reminder
- Can cover a very large area
- Durable design
- Efficient 5 stage filtration
- Quiet sleep mode
- Energy efficient
Cons
- Finding filters can be a challenge
- Quite noisy on the higher settings
LEVOIT Air Purifier
This is a much smaller air purifier that is intended for single rooms – not for whole homes. This air purifier is designed to purify the air in rooms of up to 219 square feet.
Product Highlights
We said that the LEVOIT Air Purifier will work for rooms up to 219 square feet, but the real kicker is that it can purify the air in that size of space 5 times every hour, so you could technically use it in a larger space, but it just wouldn’t purify the air as many times per hour.
In terms of actual filtration, the LEVOIT Air Purifier is a 3-stage unit. It includes an ultra-fine pre-filter for the removal of things like mold, pollen, and dander.
It then comes with the classic true HEPA filter that can remove up to 99.97% of particles 0.3 microns in size. It then finishes it off with an activated carbon filter for chemical and odor removal.
What’s also interesting is that you can choose from 3 models of the LEVOIT Air Purifier – you can get the classic one with a normal filter, and you can choose from a pet allergy filter and a toxin absorber filter too.
What’s impressive is that the LEVOIT Air Purifier has a CADR or clean air delivery rate of 135+ cubic feet per minute.
What you may also like about the LEVOIT Air Purifier is that it is not overly large. It’s fairly compact and could potentially fit on something like a nightstand or a desk.
Moreover, this unit is CARB compliant, plus it is Energy Star certified as well. While the highest settings are not exactly quiet, the nighttime mode features a noise level of just over 20 decibels, making it easy to sleep even with it running.
The Good
What impresses us about the LEVOIT Air Purifier is that it has a high clean air delivery rate, as it works great for removing dust, pollen, smoke, and more from the air.
Moreover, it’s a compact and convenient purifier that you can move from one room to another. The fact that it comes at a very reasonable price is quite a bonus too.
The Bad
What we don’t like about the LEVOIT Air Purifier is that it is only meant for a single room. When it comes down to it, 215 square feet is not that big.
Pros
- Ideal for single rooms
- Triple stage filtration
- Customizable filter type
- CARB compliant
- Good CADR
- Energy Star certified
- Night-time mode is very quiet
- Great price
Cons
- Not ideal for very large spaces
- Puts out a strong plastic smell
Alen BreatheSmart Classic Large Room Air Purifier
Going in the other direction, this is a huge air purifier capable of cleaning the air in a massive space. It might not be the cheapest air purifier, but you get what you pay for, and here you get a beast.
Product Highlights
Perhaps the most impressive feature of the Alen BreatheSmart Classic Large Room Air Purifier is that it can purify the air in a whopping 1,100-square-foot room.
That is a whole lot of space, but there is more because this unit can do this twice per hour, meaning that you could technically use this purifier for spaces even larger than 1,100 square feet. When it comes down to it, this is one of the most powerful air purifiers on our list.
What is also neat about the Alen BreatheSmart Classic Large Room Air Purifier is that you can choose from 4 different filter types. These include HEPA Pure, HEPA Silver, HEPA Fresh Plus, and HEPA Odorcell. Of course, HEPA filters are known for being able to remove 99.97% of contaminants from the air of 0.3 microns in size.
In terms of these 4 choices, the Pure is designed for effective allergen removal, the Silver is for light odors, mold, mildew, bacteria, and dust, the Fresh Plus is mainly for odor removal (particularly VOCs), and the Odorcell is for dealing with pet odors and other similar odors.
What also stands out is that it has an air particle sensor that tells you how clean or dirty the air is. Moreover, when you have this unit running on automatic mode, it will adjust its output on its own to match the air quality of the room.
Speaking of modes, besides auto mode, it comes with 4 speeds, plus a timer setting.
You might like how the Alen BreatheSmart Classic Large Room Air Purifier is made with WhisperMax technology to ensure that it is as quiet as possible, especially on the lower power settings. In case it matters to you, this air purifier is CARB certified.
The Good
What is impressive about the Alen BreatheSmart Classic Large Room Air Purifier is that it is customizable for one, and second, that you could use it for a large room or a small home; covering 1,100 square feet is quite a bit, so you could easily use it for a 1- or 2-bedroom apartment.
The fact that it can sense the air quality in a room is a great feature.
The Bad
One thing that needs to be said is that the innovacious-20nt filters aren’t cheap. Also, there appear to be some technical issues with this unit, mainly concerning it turning off at seemingly random times.
Pros
- Very powerful
- Ideal for very large spaces
- Customizable filter type
- Quiet operation
- Air sensor + auto mode
Cons
- Expensive innovacious-20nt filters
- Some issues with circuitry
Honeywell HPA300 True HEPA Air Purifier
If you need an air purifier that is fairly small and compact, and doesn’t cost a fortune, yet can still handle quite a large space, the Honeywell HPA300 True HEPA Air Purifier could be a good option to look into.
Product Highlights
The Honeywell HPA300 True HEPA Air Purifier comes with 2 stages of filtration. The first stage consists of a pre-filter that removes large particles from the air, things like dust, lint, fibers, and pet fur, plus it can also remove some odors from the air.
The second stage consists of a true HEPA filter that can remove up to 99.97% of contaminants from the air of 0.3 microns in size. It’s great for removing bacteria, mold spores, allergens, odors, and more.
The Honeywell HPA300 True HEPA Air Purifier is designed to work for rooms up to 465 square feet in size. Moreover, it can filter the air in this size room up to 5 times per hour for some really clean air.
Based on this, you could technically use this unit for a much larger room.
This air purifier features simple touch controls, and you can set it to 4 different levels. It also comes with a dirty filter indicator that lets you know when the filter needs to be changed.
Other than that, there is not too much to the Honeywell HPA300 True HEPA Air Purifier, as it is one of the more basic models. We also like how it is fairly small and compact.
The Good
The good part about the Honeywell HPA300 True HEPA Air Purifier is that while it may not be an overly fancy or advanced air purifier, it doesn’t cost that much, and it still does a very good job at purifying air, particularly because it can clean air in a 465 square foot room up to 5 times per hour.
The Bad
Something that we do not like is how it is not very energy-efficient. It will use a good deal of power, especially on the higher settings. Moreover, it’s not the quietest air purifier available.
Pros
- Powerful
- Processes air many times per hour
- 2 filtration stages
- Very simple and easy to use
- Space-friendly
- Filter change indicator
Cons
- Fairly loud
- Not very energy efficient

Buyer’s Guide
Before you buy an air purifier, there are some important things you should know. Let’s quickly take a look at the most important aspects to keep an eye on when purchasing an air purifier for a large room.
Types of Home Air Purifiers
The first thing to know is that there are many types of air purifiers. There’s ultraviolet, HEPA, activated carbon, ionic, air to air, and more. All these types have their advantages.
However, for a home air purifier, you want to go with one that includes a HEPA filter. When it comes to air purification efficiency, HEPA is the best, as it can remove up to 99.97% of airborne contaminants of 0.3 microns in size or larger.
Activated carbon is also great, but this is only good for removing some airborne chemicals, and it is great for odors. Ionic air purifiers, due to the ozone they create, are quite dangerous.
Our recommendation here, for the best results, it’s to get an air purifier with a combination of HEPA and activated carbon filters.
Air Changes Per Hour
Most air purifiers are designed for a specific size room or space, but they usually also filter the air in a room several times per hour.
For instance, we talked about one model that could purify the air in a 1,100-square-foot room twice per hour, and we looked at a model that can purify the air in a 219-square-foot room 5 times per hour. The point is that the more times per hour the unit can purify the air in a given space, the cleaner that air will be.
Clean Air Delivery Rate (CADR)
The most important thing for you to know with CADR or the clean air delivery rate is that the higher the number is, the better.
In most cases, a CADR rating of 200 will suffice. As you can see from our reviews, some models feature clean air delivery rates of 230 and up, which is perfect. Try not to go below 150.
Digital Controls
Most models today have digital controls, which is exactly what you want. Digital controls make adjustments easier.
Room Size
The final important thing to look for when buying an air purifier is what size room or area it is rated to handle. Pull out a tape measurer and measure the room or rooms you need purifying.
For instance, if you need a unit for 500 square feet, but it is only rated for half as much, then you will have problems.
Generally speaking, you do want the purifier to be able to handle a few more square feet than you actually need it for, just to ensure maximum effectiveness.
FAQs
What Types of Pollutants Can Air Purifiers Remove?
A good air purifier, particularly one with a HEPA filter, can remove pollutants including dust, hair, mites, mold, mildew, chemicals, VOCs, fumes, odors, bacteria, allergens, and more.
What are the Different Types of Air Purifiers?
There are 7 main types of air purifiers. These include ultraviolet, HEPA, activated carbon, ionic, electronic, central, and air-to-air purifiers.
Can an Air Purifier Remove the Smell of Smoke?
Yes, they can, but not all of them. To remove the smell of smoke, the best way to go is with a combination of HEPA and activated carbon filter. Activated carbon does a particularly good job of odor removal.
How Do You Choose the Right Size Air Purifier?
Use a tape measure to measure the size of the room you need the air purified, and then make your choice based on that number.
If you want to ensure that you have the most efficient unit for your needs, say if you need it for 400 square feet, try to go for a model rated for at least 450 square feet.
