How Filter-Free Systems Work?

The main question that comes to everyone’s mind when they hear about these purifiers is how they manage to filter the air if there is not any filter involved. The secret is in the physics behind the device, which involves electrostatic charging. What actually happens is the filterless air purifier electrically charges the particles of dust and other impurities in order to attract them towards the metal collector plates. Unlike the other types of purifiers, the filterless one attracts the impurities and retains them without using suction. This way, the particles stick to the metal plates as if they were magnets, thus removing them from the air.

Also known as ionic, electrostatic or ozone air purifiers, these devices have their advantages but their drawbacks as well. They are effective, although not as effective as the filter types. Also, despite the fact they do not require filter replacements, cleaning the dust particles off the metal collectors could be more hassle than replacing a media cartridge. Another concern related to this type of air filter is the ozone which is often released during the process. Ozone is a harmful gas that should not be inhaled but, unfortunately, some ionic purifiers emit it while operating.

Reasons to Make the Investment

With so many different types of air purifying systems on the market these days, you might be wondering whether it is worth investing in a no-filter air purifier or not. Our recommendation to you would be to make the investment, but do not take our word for it without informing yourself about the capabilities of these appliances first. In the following lines, we will tell you why you should invest in an air purifier which does not actually feature a filter. Therefore, continue to read if you are interested in this topic.

    • Less Maintenance Work

One of the biggest reasons why some people stray from the classically designed air purifiers and turn to filterless models is because there is less maintenance work involved with them. This is all due to the fact that the air purifying appliances do not feature a filter, so you do not have to check if the filter needs to be replaced or anything else. The only actual maintenance work required with filterless models is to remove the dust that gathers on their surface, but this is not a tiring or time-consuming chore.

    • No Additional Purchases

As time passes, you have to make additional purchases if you go for an air purifier which comes with a filter. The additional purchase we are talking about is replacing the filter, of course. Well, with a filterless system, this investment won’t exist, thus you won’t have to spend more money as time passes. For those who want to stick with a certain budget and who do not want to waste their money, these types of filtration systems are a real heaven sent.

    • More Effective at Killing Germs, Viruses, and Bacteria

Another highlight filterless air purification systems boast is they have a higher efficiency when it comes to the removal of bacteria, germs, and viruses. Therefore, the quality of the air indoors is a lot higher, and you are not exposed to health issues like colds or the flu. While classic purifiers which feature filters are capable of removing these health threats as well, they are less effective when compared to their filterless counterparts due to the fact that they do not release negative ions.

    • High Efficiency in Removing Airborne Pollutants

The ultimate reason to invest in a no filter air purifier is the fact that it boasts a high efficiency in the removal of all types of airborne pollutants. Of course, other types of air purifiers boast this capability as well, but the ionic technology these devices feature makes them more ideal solutions to go with as they can even handle eliminating the really small particles from the air. They can do this due to the release of the ions that attach to the microscopic particles, making them larger so that they are removed more easily.


Types of Filter-Free Air Purification Systems

The state of the environment you spend most of your time in and your health are both linked to the quality of the air you breathe. This is the reason why so many people are buying and using air purifiers, ensuring pollutant-free air indoors with the help of these appliances. If the perks provided by filterless air purifiers have impressed you and you want to use this type of air filtration system, you need to be aware of the fact that there are three different types of systems to choose between, more precisely electrostatic precipitators, ultraviolet purifiers, and ozone-based systems.

    • Electrostatic Precipitators

These are highly efficient and effective appliances capable of removing dust particles by using a high-voltage electrostatic charge. They are accumulated on charged plates which contain thin wires, being completely eliminated from the air once they enter into contact with the surface.

    • Ultraviolet Purifiers

Ultraviolet models use ultraviolet light to destroy microorganisms which linger in the air indoors, microorganisms like germs, viruses, bacteria, mold spores, and so on. What makes ultraviolet air purifiers a massive success is the fact that they are superior to other types of air filtration systems when it comes to energy efficiency.

    • Ozone-Based Systems

Last but not least, we have the ozone-based purification systems that use ozone or a combination of oxidizers to remove the impurities from the air. Best of all, they even do a good job at killing microorganisms, like bacteria, germs, model, and mildew. Additionally, they are easy to operate, safe, and they do not consume much energy when operating either.

What to Look in a Filterless Purifier

As a person who is well aware of the importance of leading a healthy life, you know it is extremely important to invest in a top of the line filter-free purifier. If your heart is set on a filterless model, then make sure you first inform yourself about what you have to look for when making this purchase. This way, you will be well prepared when you go out shopping and you definitely won’t make a choice that will fail you.

Coverage Area

The first spec you have to look into when purchasing this device is the square footage which is listed for it. You need for this square footage to be slightly greater than the square footage of the room or area where you intend to use the device for it to be able to purify the air as effectively as possible. For example, if you want to place the filterless air purifier in a room measuring 80 square feet, make sure the purifier is said to be able to remove impurities from the air in rooms measuring at least 85 square feet.

High Percentage of Eliminated Airborne Particles

To establish whether a certain model is effective at removing the pesky airborne particles or not, you have to look at the percentage of particles it can eliminate from the air. The best quality purifiers are those who are capable of removing at least 99 percent of airborne particles, so these are the ones you have to keep an eye on.

Energy Consumption

The amount of energy it consumes is another aspect you have to take into consideration to avoid spending a ton of money on the energy bills. The easiest method to establish if the model you are interested in is actually energy efficient is to look for the Energy Star certification as it is only given to the most efficient models out there.

Noise Output

No matter if you want to place it in rooms like the nursery or the bedroom, rooms in which silence is required during the night, or you want to place it anywhere else around the house, you must make sure the model you invest in maintains a quiet operation. This way, you avoid getting bothered or distracted by it while you sleep, work, or simply sit and relax.

Extra Features

Just like most appliances, they can come with extra features that make them more convenient to use. These extra features differ from one model to another, and it is smart for you to invest in a purifier that has some useful additional features. Some of the best extra features to be on the look for are backlights, LCD screens which make changing the settings easier, and even handles or casters that make it easy to move it from one room to another.


Of course, we cannot overlook the warranty aspect. As with all types of purchases, it is essential to make sure the manufacturer covers the filter-free air purifier for a decent or generous amount of time. This way, in case anything happens to it after you purchase it, you will be able to have it fixed or replaced free of charge rather than spending a ton of money on the operation.


The filterless design of these air purifiers makes them the most convenient choices to go with as they do not actually require maintenance work. Furthermore, costs are saved as you do not have a filter to replace and worry about anymore. However, this implies that not all systems can handle purifying the air in large spaces as well as their filtered counterparts do. But as you have already found out, this is not a general rule, most of the products we presented in our top handling large areas with ease. Our top pick, the Airfree Lotus, is able to purify the air in a room or space which measures up to 650 square feet, so efficiency is not an issue with it. Additionally, it boasts a compact design, and it delivers a low 52-watt power consumption which ensures you will actually save money in the long run if you use it. Another noteworthy product when it comes to area coverage is the RxAir Plus with TiO2 UVC1001B that can handle areas of up to 800 square feet. Also, we have to remind you of the AirFree Onix 3000 before we end this article as it can be used in spaces of up to 650 square feet, it is completely silent when operating, and it has a staggering efficiency rate of 100% in terms of air pollutant removal.


Frequently Asked Questions

Are filterless air purification systems as effective as filter air purifiers at removing indoor air pollutants?

The answer to this question solely depends on the filterless system at hand. If you have purchased and are using a quality device, then you need not worry that a filter featuring air purifier could have done a better job at clearing the air indoors of pollutants and impurities. However, if you cheap out and buy a lesser performing device, it is obvious you will not receive the best air cleaning performance possible. These two types of devices cannot be compared to each other as they both deliver great results if they are built with innovative, high-performing technologies.

Are ozone-based systems dangerous for my health in any way?

Some promote ozone-based systems as being 100% safe, while others find no positive sides to these systems. The truth is somewhere in the middle as indeed, the ozone these systems generate is harmful to your health. However, this is not entirely true as ozone is produced in small quantities, meaning you are not in peril of being affected by the output of these devices. What you should take away is that ozone-based air purifiers are not an actual threat to your health as they stand between healthy parameters of ozone emissions.

Do no-filter air purifiers help save money as opposed to their filter featuring counterparts?

Yes, filterless air purification systems do indeed help save a lot of money in the long run as they do not require you to ever make filter changes due to their no-filter design. As opposed to them, filter featuring systems require you to make periodical filter changes, meaning that in the long run, you end up spending hundreds of dollars on maintenance work.
