There are all types of unseen contaminants floating around in the air of your home. Dust, mold spores, pet dander, and pollen are just a few of the unwanted guests you’re breathing in. These particles are unhealthy, leading to allergy symptoms like coughing, sneezing, and congestion. One way to combat these issues is to purchase the best filterless air purifier. These clean the junk out of the air, making it cleaner, fresher, and healthier. The absence of filters means no replacement is needed, saving you effort and money in the long run.
To be sure you have the highest quality air purifier, there are a few features worth noting. One is the type of cleaning method used by a particular model, as different types have different capabilities. An air purifier’s coverage area shows the maximum size the room should be for it to work properly. You should also look at the dimensions, especially if using it in an area with limited space.
In order to help you decide which of the best filterless air purifiers is for you, we spent countless hours scouring manufacturer’s information, scanning product details, and features, and reading hundreds of customer reviews. Then we created a comparison table, wrote up some in-depth product descriptions, and added a buyer’s guide to help you choose the right model.
If you’re looking for the best filterless air purifier for a small or medium room, the Airfree P1000 is one of the top models available. It doesn’t use any fans at all, so you won’t hear a thing when you turn it on. All you’ll notice is the soft blue light and some slight heat radiating from the machine to even tell you it’s working.
Instead of bulky filters that require replacement or cleaning, this air purifier uses Thermodynamic TSS Technology to clean the air. The air in your room is pulled into the unit using air convection. The Airfree then heats the air coming through the machine to almost 400 degrees Fahrenheit, destroying the microorganisms it contains. This includes mold, dust mites, pollen, viruses, bacteria, pet dander, and much more.
Once all those nasty particles have been destroyed, and the air has been sterilized, it is cooled off and sent back out into the room. This circulated air is cleaner, healthier, and free of allergens.
Another benefit of this filterless air purifier is that it doesn’t emit any harmful ozone. In fact, it can actually reduce the ozone in your home by about 26%, so your asthma symptoms should be reduced when using this model.
There is also a blue night light on this machine, which looks lovely and creates a relaxing atmosphere in any room of your house. This light is adjustable, using a small black dial to create the ambiance you prefer.
This stylish little device is CARB-certified, so it meets the strict air quality standards set by the California Air Resources Board. It is also energy efficient, keeping your energy bill nice and low, even when used every day.
Though it isn’t the cheapest filterless air purifier available, the Airfree T800 model is still one of the most popular products there is. It doesn’t have replaceable filters, either, making it even more convenient to use over other types of air purifiers.
This model uses ionization, sending out billions of electrons into the air, which then attach to the particles floating around, converting them into negatively charged ions. Then all those unwanted contaminants are pulled into the machine, where they bond with the positively charged collection tube inside. They remain there, sticking to the tube, until you turn off the machine, pull out the tube, and clean it. Any larger dust particles that are too big to bond to the tube fall right to the ground, where they are easily swept up or vacuumed.
As for cleaning, it is a simple job. You only need to remove the tube, give it a rinse with some water and a soft cloth, and then dry it thoroughly. This only needs to be done once or twice a month, depending on how dusty your house is.
As well as getting rid of the dust in the air, this device also gets rid of pollen, smoke, and pet dander. In fact, it can remove particles as small as 10 nanometers, so almost any unwanted pollutants and allergens are taken care of.
The Airfree T800 purifier is great for larger rooms, due to its huge 540 square feet coverage area. It is capable of cleaning the air in a room of this size or smaller in about five hours. Best of all, it only runs at twenty one decibels, so even if it is right next to you, you’ll barely hear it.

Since it has no fans running to clean out the air, the Airfree Lotus is one of the best silent filterless air purifier models on the market. Instead of fans and replaceable filters, it uses a patented Thermodynamic TSS Technology to clean all those nasty particles out of the air, making it cleaner and healthier for you and your family to breathe.
This technology is quite unique, pulling the air into the machine and then heating them up to almost 400 degrees Fahrenheit. Microorganisms like dust, pet dander, mold, pollen, tobacco, viruses, and bacteria are destroyed by this heat. The air purifier then cools off the clean air and sends it back out into the room.
Another benefit of this technology is that it is completely safe for your family. It doesn’t emit any ozone whatsoever and actually decreases any ozone already in the air by about 26%, making it even safer for your family to inhale. It also doesn’t emit any UV light or ions, producing only healthy air free of contaminants. The Airfree Lotus also consumes very little energy, so it’s a healthy choice for your wallet as well.
The Lotus name also comes from the fact that this model was designed with the lotus flower in mind. It has lovely petals, which you can open up or leave closed. Within the petals is a stylish light that is meant to calm and relax you while the machine cleans the air. This brightness of the light is adjustable, plus it has a few color options to choose from, so you can create the ambiance you want. It also makes a handy nightlight for any bedroom in your house.
The best filterless dust air purifier doesn’t have to cost you a fortune, as the Ionic Pro 90IP01TA01W proves. It has a great low price that can fit into any budget, plus it has washable filters so that you won’t be burdened by any extra replacement costs. This model is also energy efficient, keeping your energy bill nice and low, no matter how often you run it.
This air purifier has a sleek tower design, and though it’s tall, it should be able to squeeze into a corner and out of the way. The filter is a collection blade, which traps up to 99.9% of all the airborne particles that may be contaminating the air in your home. This includes normal household irritants like dust, pollen, and pet dander, but also goes a bit further, removing viruses, bacteria, and other contagions. Even smoke and odors are taken care of, so the air smells fresh and clean.
The collection blade is front-loading and easy to remove, so you can clean it quite easily. This should be done once a month, using simple soap and water for the blades and a vacuum for the internal parts. You also need to let the blades dry for a full 24 hours before using the machine again to avoid any damage to them or the air purifier.
There are three speeds, low, medium, and high, which you can use for fast cleaning or maintaining the air quality. There is also a clean indicator, so you know when the proper air quality has been reached. No matter what speed you choose, the air purifier is almost silent, with only a slight hiss on the highest level.
An air purifier can get rid of all those unwanted particles in the air of your home that are causing allergy symptoms like stuffy noses and congestion. They can also remove those lingering cooking or pet odors you may not enjoy. The purifiers with filters do these jobs well but add repeated replacement costs to the initial price. To save some money without losing any of the benefits, you could try one of the models in our best filterless allergy air purifier reviews, which don’t use regular replaceable filters. Of course, you still need to check out the features each one has to offer to be sure it is the right one for you.
The main advantage of having a filterless air purifier is that it saves you money in the long run. Filtered air purifiers come with a few different types of filters, most of which require replacement every three to six months, and sometimes those filters can cost almost as much as the air purifier itself.
The models above don’t have this issue since they don’t use regular filters. Instead, they require a simple rinse and a thorough drying once every month or two, or no cleaning at all. You spend less money and have very little maintenance to deal with, making them a much cheaper and more convenient option. Filterless air purifiers are also quiet, so you won’t even notice them while they are running.
A filterless air purifier is usually very easy to use, with limited features to deal with, but there are a few things you should look into before you buy one. This will ensure you are getting exactly what you want to deal with the air quality issues in your home.
The products in our reviews use a few different cleaning methods to get rid of the allergens in the air. The two Airfree products use thermodynamic sterilization, which sends the air through heated air to destroy the allergens and pollutants, killing any microorganisms you would otherwise be breathing in.
Ionic Pro 90IP01TA01W uses ionization. Many airborne particles are made of positively charged ions. When this air purifier emits the negatively charged ions, it attracts those contaminants, bonding to them until a cluster is formed. When this cluster is large enough, it falls to the floor or collects in the tube or plate inside the machine.
The coverage area is an important feature for any type of air purifier, with or without a filter. This number shows you the maximum room size you should use the air purifier in. Keeping at or below the coverage area ensures the product will work at its peak performance.
For instance, the Airfree Lotus Filterless Air Purifier has a coverage area of 650 square feet. In a room of this size or smaller, it will work quite well, cleaning the air in the specified time frame. If you tried to put it in a room of 700 square feet, it would not work as efficiently, taking much longer to clean the air. It will likely not be able to maintain the proper air quality level as well.
One of the best features of the filterless air purifier is the fact that they are the quietest type there is. These purifiers don’t have internal fans, so there is almost no noise to speak of. Even the Ionic Pro 90IP01TA01W, which has three cleaning speeds, barely emits any noise. This means you can place it, or any of the other models in our reviews, right next to you and still not be disturbed by them. This makes filterless models the best choice for bedrooms or nurseries since they won’t interfere with anyone’s beauty sleep.
The dimensions of any product should be one of the main features you look at to be sure it will fit in the space you have. A large, bulky model won’t fit into a small room, especially if you want to put any furniture in there. Measure the space you have available and try to find a product with the features you prefer that will fit into that space. Of course, if you have a large room with plenty of open areas, this likely won’t be much of an issue.
Filterless air purifiers do come in a variety of sizes. If space is an issue, you may want to consider a model that is thin, but tall. This allows you to squeeze it into a smaller area.
Short, compact air purifiers can be placed on a desk or counter, out of the way, leaving your floor space empty if needed. Just be sure to leave some space around them, no matter what size they are, so they can circulate the air properly.
The warranty of a filterless air purifier protects you from any unexpected issues with the product, especially defects in the parts or manufacturing errors. The longer the warranty lasts, the more time you have to try out your air purifier to be sure it is working properly. This is especially important if the issues don’t show up right away, which occurs more often than you may think. A two-year warranty, like the one offered with the Airfree P1000, gives you a bit of extra time to test out the machine to be sure there are no issues to deal with.
Though the features described above are the main ones to look for in any filterless air purifier, some models come with a few extras that make them a bit more convenient. One is multiple speeds, like on the Ionic Pro 90IP01TA01W. Higher speeds increase the rate of air cleaning, while lower speeds maintain the air quality levels you desire.
A night light is also handy, especially if you’re using the air purifier in a child’s bedroom. This adds some soft lighting to the room without blinding anyone or keeping them awake. The Airfree Lotus Filterless Air Purifier even has a few color options to choose from, so you can create a relaxing ambiance in any room of your house. A dimmer switch for the night light lets you turn it up or down, depending on the time of day or your personal lighting preferences.
Energy efficient certifications is also a must. An air purifier will likely be used every day, so you don’t want it sucking up too much energy. If it does, your energy bill will be much higher, costing you a great deal of money over time.
The best filterless air purifier doesn’t have filters that need replacement every few months or so, saving you a great deal of money. They also don’t include fans, making them a much quieter choice for your home. All four of the options we’ve reviewed above are great choices, but let’s take another look at a few of them.
The Airfree P1000 is stylish and compact, with the Thermodynamic TSS Technology that destroys the contaminants, leaving nothing left to clean up. It also has a decent coverage area, is CARB certified, energy efficient, and includes an adjustable blue night light.
The Airfree Lotus Filterless Air Purifier and is energy efficient, has a 650-square feet coverage area, a cool lotus design with petals that open, and an adjustable night light with multiple color options.
