Best Filterless Air Purifier: Our Top Picks for 2023

Is a filterless air purifier right for you?

If you’re looking to improve the air quality in your home or office, you’ve probably come across both filter and filterless options. And if you’ve arrived at this article, you have likely chosen to go with a filterless option.

With minimal cleaning, lower ongoing expenses, and high-quality air purification, filterless air purifiers can be a great addition to your space.

But, you need to make sure you choose the right model for the best results and safest operation.

Best Practices For Using A Filterless Air Purifier 

When compared to a HEPA filter’s straightforward filtration method, filterless air purifiers are more complicated.

Instead of trapping and removing airborne pollutants and particles from the air, filterless air purifiers change the particles themselves.

As a result, the chemical processes can cause byproducts like ozone to be produced that may be harmful in large quantities or to certain people with respiratory issues.

For the safest operation of a filterless air purifier, be sure to consider models that include an activated carbon filter or add a carbon filter to your space to help remove ozone and other potentially harmful volatile organic compounds (VOCs) from the air.

You should also consider placing filterless air purifiers farther away from people and pets to further minimize the risk of harmful inhalation.

Top 7 Filterless Air Purifiers

1. B-1000 Ionic Air Purifier with UV-C Sanitizer

The B-1000 Ionic Air Purifier is a filterless option that uses three different types of purification to help address all of the airborne pollutants your home may experience.

It supports a room of up to 1,000 square feet with the ability to remove smells, larger particles, and even germs.

The primary filtration method of the B-1000 is ionization, which works to charge the particles so that they land on surfaces that are easily cleaned. It’ll address units as small as 0.1 microns but also works with dust, dirt, mold, and other common allergens.

Additionally, it includes a UV-C light that breaks down the microorganisms in the air that are brought into the air purifier for filtration, helping to remove the smallest of particles, like viruses and bacteria.

Finally, the activated carbon layer helps to remove smells and address any ozone created by the machine so that it’s safer to be around.

The B-1000 also has two speeds with whisper-quiet purification to help you control the noise levels so that it can be used at any time of the day.


  • Ionization, UV-C, and activated carbon filtration
  • Supports up to 1000 square feet
  • Quiet operation
  • Low ozone production range


  • Cleaning can be difficult
AirFree T800 Filterless Silent Air Purifier

2. AirFree T800 Filterless Air Purifier

AirFree’s T800 Filterless Air Purifier is a small-scale model that uses heat as its method for purifying the air.

It supports just 180 square feet of space but removes 99.99% of airborne pollutants with no ozone emissions, so it’s great for bedrooms or offices.

AirFree’s Thermodynamic TSS works by heating the air that flows through the device to 400 degrees Fahrenheit, effectively killing all of the natural organisms it reaches.

The byproduct it creates isn’t ozone but is instead carbon dioxide, which is harmless to breathe in.

Another benefit of this kind of technology is that it requires no cleaning or filter replacements due to the heating element burning all harmful particles it affects.

Plus, it’s effectively silent because it doesn’t use filters or fans, so it can be left on overnight without worry.


  • No ozone emissions
  • Removes 99.99% of particles
  • No cleaning required


  • Does not remove smells or VOCs
  • Only 180 square feet of effective range

3. Envion Ionic Pro Turbo Air Purifier

Envion’s Ionic Pro Turbo Air Purifier works to address your home’s allergens and airborne pollutants through ionization. It supports spaces as large as 500 square feet with three cleans per hour, making it ideal for offices or bedrooms.

The Ionic Pro uses a collection panel to remove some of the pollutants that it filters during the ionization process before depositing negatively-charged particles into the air.

These particles attach to airborne contaminants and fall to be easily cleaned. However, the collection panel also needs to be wiped off every few months to ensure that the panel can collect particles effectively.

This model also includes a germicidal chamber within the filtration process that kills bacteria and viruses, as well as an ozone filtration element to help minimize emissions.

The Envion Ionic Pro Turbo is incredibly quiet, with three different fan settings to make sure it’s always addressing your needs without creating excess noise.


  • Ionization with ozone and germ treatments
  • Quiet operation
  • Easy to clean


  • Doesn’t address VOCs

4. AirFree Iris 3000 Filterless Air Purifier

The AirFree Iris 300 Filterless Air Purifier uses thermodynamic TSS technology to superheat airborne particles in a room up to 650 square feet.

It’s great for larger spaces like family rooms or basements and can be placed anywhere without concern over ozone emissions.

All of the air that the AirFree Iris 3000 reaches is treated by the heating element to disintegrate the natural elements of the pollutants so that your air is cleaner to breathe.

With no ozone production, it doesn’t require an additional filter, but its lack of carbon filtration means that odors won’t be addressed without an additional appliance.

This model can be set and forgotten thanks to no maintenance requirements and is silent enough to be placed anywhere.


  • 650 square feet of coverage
  • No ozone emissions
  • No maintenance required


  • Doesn’t address odors or VOCs

5. Clarifion Air Ionizers

Clarifion’s Air Ionizers are a set of multiple ionizer devices that can be plugged into any standard outlet in your home or office.

They’re incredibly portable, and a single set can be used to address multiple rooms for the price of one single device.

They support up to 150 square feet each, which makes them great for bathrooms, but a lack of an ozone filter means they might not be ideal for a bedroom.

Each ionizer works to negatively charge the air so that particles lump together and fall downwards to be easily cleaned up.

Vacuuming, sweeping, and lint rolling can all be ways to remove the fallen particles so that your air quality can increase, allowing you to breathe better.

However, they don’t impact odors and VOCs.


  • Portable
  • Can cover multiple rooms
  • Whisper-quiet


  • Small effective range
  • No odor removal

6. AirFree Tulip Filterless Air Purifier

AirFree’s Tulip Filterless Air Purifier is a mid-range model that supports up to 450 square feet of space with thermodynamic TSS technology.

This silent model can operate 24/7 without producing any ozone or requiring maintenance, so it’s great if you’re looking for a low-maintenance model.

The Tulip Filterless Air Purifier will use an internal heating system to superheat the air to 400° F and then cool it to be released back into the room without the pollutants it entered with.

This method of air purification addresses dirt, dander, hair, smoke, and germs with 99.99% efficiency for a reliable source of cleaner air.

But, while it helps remove the particles that carry smells, it doesn’t actively remove the odor-causing VOCs.


  • Silent operation
  • No maintenance required
  • No ozone emissions


  • Doesn’t remove odors

Filterless Air Purifier – FAQs

Are Filterless Air Purifiers Safe?

In most cases, yes. All filterless air purifiers must fall within specific guidelines for the concentration of ozone produced (less than 0.05 ppm) to be able to be sold.

However, even small amounts of ozone can be harmful if inhaled in large quantities, so it’s better to stay further away from units that do produce ozone or add a carbon filter to the room.

Do I Need A UV-C Element For Purification?

No, your filterless air purifier doesn’t need to have a UV-C element to be effective. Ionizers impact many airborne particles similarly to UV-C light, but the addition of a sanitizer can help to better address smaller particles like germs, viruses, and bacteria.

What’s The Difference Between HEPA and Filterless Air Purifiers?

HEPA filters use mechanical filtration – physically removing or absorbing the harmful airborne pollutants that are pulled through the filter.

Filterless air purifiers chemically alter the particles in the air to help make them easier to collect or destroy them entirely.
