How to Choose a Filterless Air Purifier
When buying a filterless air purifier, there are a few features you should always keep in mind.
Purifying Technology
First of all, you should consider which technology you want to go for. Among filterless air purifiers, you can opt for purifiers that use ionization or ultraviolet purifiers. It all depends on the nature of the contaminants.
Area Coverage
Room coverage is another essential thing. You should opt for an air purifier with greater coverage. You should measure the area (in square feet) to ensure you get the right model.
Energy Efficiency
Next is the energy consumption. Of course, a purifier that uses excess or is wasteful with electricity is no good for you. Always opt for energy-efficient models.
Noise Production
Another vital feature to look for happens to be the noise level. The quieter an air purifier is, the more preferable it is going to be for the entire household (especially during the night).
The Size
Lastly, the size of the air purifier should be taken into consideration. A larger and heavier purifier would be difficult for you to move around. Such a model will also take up more space. Try and go for compact yet powerful units.

Review
This Airfree filterless air purifier may be small in size, but it is definitely no less (performance wise) than many others. It has a ceramic core which can reach up to a temperature of 400 degrees Fahrenheit.
The Airfree air purifier doesn’t rely on a HEPA filter or an ionizer to purify the air. Instead, it makes use of something known as the Thermodynamic TSS technology. This purifies the air by completely eliminating all contaminants present in the air instead of filtering them out.
It pulls the air in and, with the help of its ceramic core, which heats up to 400 degrees Fahrenheit, it completely sterilizes the air. This device then cools the air before sending it out into the room again.
The best part about this filterless unit is that there are no filters for you to replace and maintain. There are no ion emissions to worry about either. All you have to do is simply turn this little device on and let it do its work. Moreover, it can clean the air in your room up to 99.99%. This means it provides you with completely clean (bacteria-free air).
Along with that, it also deals with household allergens which include pet dander, mold, dust mites, etc. Another feature of this purifier is that it is entirely silent. So, you can use it comfortably, even in your bedroom.
Bottom Line
The Airfree Air Purifier Onix3000 is a brilliant unit if you are looking for a small, noiseless air purifier. It is free from all types of filters and doesn’t require a lot of care and maintenance to have it working effectively. It is a good choice for anyone looking for a hassle-free air purifier.

Review
This Ionic air purifier has a slim and sleek design making it easy to fit into any kind of interior. This purifier uses negative ions to purify the air in the household. It functions by emitting negative particles into the air.
These negative particles latch on to the contaminants such as dust mites, pet dander, mold spores, bacteria, etc. This makes the particles heavier and causes them to sink and settle on the surface. The settled particles can be swept up and cleaned, thus leaving the air clean for you to breathe.
This purifier is a good option for all those who suffer from various allergies and even people who suffer from breathing problems such as asthma. The modern technology effectively gets rid of all pollutants and provides everyone with cleaner air to breathe. It also frees the air of all foul smelling odors caused by smoke and mold, as well as the smell of pet dander.
Since this purifier doesn’t use any filters, it is easier to clean as well. The purifier itself does not take a lot of space, but still has a room capacity of 500 square feet. Moreover, it doesn’t need a lot of energy to function effectively. On average, it consumes less energy than a fluorescent bulb or nightlight would.
Bottom Line
Overall, the Ionic Pro 90IP01TA01W Air Purifier is a good buy at a reasonable amount. It has all the features of a good air purifier and more. It is portable, which means it can be used in multiple locations and can be set up easily (where and when needed). Although it does require frequent cleaning, the entire cleaning process is an easy one.
Pros
Very Easy to Clean
Easy on the Budget
Portable Air Purifier
Doesn’t Make a Lot of Noise
Provides Crisp and Fresh Air
Doesn’t Consume a Lot of Energy

Review
Like all other air filters from Airfree, this one also makes use of the Thermodynamic TSS Technology. This technology enables the air purifier to sterilize the air and make it pollutant-free up to 99.99%. It does so by heating up the polluted air and purging it from all types of bacteria and germs.

How Does a Filterless Air Purifier Work?
Filterless air purifiers, as the name suggests, don’t make use of filters at all. Instead of using filters, these air purifiers emit a charge which latches onto the contaminants in the air. After the particles are charged, they are then gathered on an oppositely charged plate. This works very differently than filter-based air purifiers which usually filter the polluted air and output the clean air.
Although both the filter and filterless air purifiers are beneficial in different ways, the filterless has some perks you won’t find in filter-based air purifier model.
Which Environment is a Filterless Air Purifier Best For?
The Air Oasis 1000G3 is fit for the following environments:
Bedroom
This device will help remove particle pollutants and bad odors from your bedroom to allow for a peaceful night. Place it far from the bed so the light from the power adapter doesn’t disrupt your sleep.
Offices
This filterless purifier will help you and your co-workers stay focused and feel comfortable in the office by removing harmful pathogens and improving the indoor air quality. You can also use multiple devices for efficiency.
Lounge Room
This device is also great for the most commonly used area in our home. It’ll make sure your indoor air quality is optimal for your guests or your family, as this air purifier will filter out odor and stale air in your lounge room.
Aspects to Consider Before Buying a Filterless Air Purifier
Here’s what you should be looking for in a filterless air purifier:
Energy Usage
An air purifier shouldn’t decimate your electric bill. Look for the Energy Star logo on the packaging to verify energy-efficient units.
Room Size
Most air purifiers list the suggested room size. Pick one that matches the size of your space for effective air purification.
Warranty
Some manufactures offer generous warranties to cushion users from product-related malfunctions. Why settle for a two-year warranty when you can find one that’s good for 10 years or a lifetime.
Noise
Watch out for an air purifier’s noise rating to ensure quality sleep. We recommend devices with a rating of 30 decibels or lower.
Filtered vs Filterless Air Purifier – How Do They Compare?
Both filtered and filterless air purifiers improve indoor air quality by removing pollution.
You can use both to eliminate harmful chemicals and gaseous pollutants from the air and neutralize unpleasant odors to reduce the chances of airborne diseases and relieve the symptoms of respiratory conditions like asthma.
Neither is perfect. The filtered purifiers can trap dirt, reducing their effectiveness, while filterless purifiers may allow some microorganisms to escape.

Types of Filterless Air Purifiers
There are two different types of filterless air purifiers you should know about.
Ionizers
These are perhaps the very first type of air purifiers made. They work with electrically charged plates.
The plate with the opposite charge collects all the pollutants on it and removes them from the air for a cleaner environment to breathe in.
Ultraviolet Purifiers
The ultraviolet light is very powerful. It can easily help erase particles like germs and bacteria from the air. This type of air purifier doesn’t need a lot of electricity to function and ensure you have clean air to enjoy.
How to Clean and Maintain a Filterless Air Purifier
Filterless air purifiers – which should be cleaned once a month – are the easiest devices to maintain. Here are the steps:
- Unplug the purifier from the power source
- Lift and remove the top cover
- Remove the ionic blades with a large, metal object
- Clean the blades with a dry, or slightly damp, cloth
- Wipe out any dirt on the covers and exterior
- If the blades are damp, wait for about 24 hours before reassembling; otherwise, reassemble immediately
- Securely reinsert the collection boards back into the ionic base
- Return the collection blades’ cover and the top cover
- Plug the device into the power source and start it
Conclusion
Overall, filterless air purifiers are a good way to deal with a polluted air space indoors. They can effectively help reduce pollutants and allergens from the air and create a healthier environment. The best part is they are easier to maintain than filter-based air purifiers because they don’t use filters, which must be changed with time.
We hope our best filterless air purifier list aids you in finding the right product for you to invest in.
