Air purifiers have become an essential home appliance in recent years due to increased levels of indoor pollution and allergens. These devices help in maintaining good indoor air quality by capturing and removing particles like dust, pollen, pet dander, and even airborne bacteria and viruses. Among the various types of air purifiers available in the market, filterless air purifiers offer an innovative and efficient alternative to traditional ones that require regular filter replacements.
Filterless air purifiers use advanced technologies like electrostatic precipitation, ionization, or photocatalytic oxidation to clean the air without the need for replaceable physical filters. This not only reduces maintenance costs and efforts but also ensures consistent performance over time. Additionally, filterless air purifiers are often quieter and more energy-efficient compared to their counterparts with filters.
When choosing the best filterless air purifier, it’s essential to consider factors such as room size compatibility, noise level, energy consumption, and the type of indoor pollutants it can effectively remove. Individual needs will determine which air purifier technology is most suitable – for instance, a device featuring ionization may be better suited for people with allergies, while photocatalytic oxidation may be more effective in removing volatile organic compounds (VOCs) and odors.
With these considerations in mind, we have devoted our time and effort into researching and analyzing the best filterless air purifiers available, allowing you to make an informed decision in achieving a cleaner and healthier living environment.

AirFree T800 Filterless Air Purifier
This AirFree T800 is a low-maintenance, energy-efficient choice for small rooms, but it may not be suited for larger spaces or if you’re sensitive to heat.
Pros
- No filter replacement needed
- Silent operation
- Compact and portable
Cons
- Emits heat during operation
- Not suitable for larger rooms
- Wired design may cause stability issues on hard floors
After using the AirFree T800 Filterless Air Purifier in our home, we can confidently say that it offers a natural way to clean the air without all the additional costs and maintenance of other air purifiers. The patented Thermodynamic TSS technology uses heat to remove allergy-causing microorganisms, making it an excellent choice for those who suffer from allergies.
The filterless technology not only eliminates the need for filter replacements but also the need for regular maintenance. All you need to do is occasionally wipe the exterior with a cloth to keep it clean. Furthermore, it doesn’t emit ions, UV light, or any other harmful wastes back into the air, which is a huge plus in our book.
While we appreciate the compact, modern design which saves space, it’s worth mentioning that this particular model is best suited for small rooms. If you need an air purifier that can handle a more extensive area, you might want to consider other AirFree machines designed for larger spaces.
Another aspect worth noting is that, although the unit is designed to be energy efficient and eco-friendly, it does emit heat during operation. If you’re sensitive to heat or live in a hot climate, this might be a drawback for you. Additionally, the wired design might cause stability issues on hard floors, as one leg may not sit evenly when placed on a solid surface.
In conclusion, the AirFree T800 Filterless Air Purifier provides an easy-to-use, low-maintenance solution for those in need of a purifier for a small space. However, if you require air purification in a larger room or are sensitive to heat, you might want to explore other options within the AirFree product line.
Airfree P2000 Filterless Air Purifier
The Airfree P2000 offers an efficient, quiet, and low-maintenance option for those seeking a filterless air purifier to improve their indoor air quality.
Pros

- No additional costs for filters or replacement parts
Cons
- Requires continuous operation for optimal benefits

After recently using the Airfree P2000, we appreciated its modern design and ease of use. Straight out of the box, setup was as simple as plugging it into an outlet and allowing it to work its magic. We took note that, for the best purification effects, it’s essential to keep the device running continuously in open spaces with ample airflow.
What truly impressed us was the absence of noise while the purifier was functioning. This makes it an excellent fit for bedrooms, nurseries, and offices where noise-sensitive individuals may be present. The silence is achieved through its filterless air purification method, which relies on boiling water to sterilize the air and a ceramic core to effectively treat up to 550 sq. ft. of space.
However, this Airfree P2000 comes with certain drawbacks. For those with larger homes or rooms that exceed 550 sq. ft., a single unit may not provide sufficient coverage. Another minor issue is the blue glow night light, which may disturb those sensitive to light during sleep.
In conclusion, the Airfree P2000 is a solid choice for those seeking a low-maintenance, silent, and effective air purifier that eliminates various allergens and air pollutants. However, its coverage area may be limiting for some users, and the blue glow night light could be an inconvenience for certain individuals.
Airfree Tulip Filterless Air Purifier
The Airfree Tulip Filterless Air Purifier is a solid choice for people seeking cleaner air, with its effective bacteria and allergen removal and low-maintenance features; however, its minor flaws might discourage some buyers.

Its sleek tulip shape and built-in night light with ten color options add a nice touch to any room while doing its job of keeping our air clean.
However, we noticed that the Airfree Tulip Filterless Air Purifier might not be suitable for larger rooms, as its coverage area is limited to 450 square feet. Additionally, it’s challenging to determine the purifier’s effectiveness without visible proof since there are no filters to inspect. This might make potential buyers question whether it is worth the investment. Finally, although some users experienced allergy relief, others did not, indicating that its ability to alleviate allergies might be inconsistent.
In conclusion, the Airfree Tulip Filterless Air Purifier is a reliable, cost-effective, and environmentally friendly option for those seeking cleaner air in their homes. However, potential buyers should consider its coverage area limitations and the lack of tangible evidence demonstrating its effectiveness before making a purchase.

However, the Iris 3000 performs best in spaces up to 650 sq. ft., so it may not be suitable for larger rooms. Additionally, the output air is slightly warm, which should be taken into consideration when choosing a location for the purifier. Lastly, it would be even more beneficial if it had more additional features such as a smart app or a timer setting.
Overall, the Airfree Iris 3000 offers an attractive, efficient, and low-maintenance solution for smaller living spaces. With its filterless technology and silent operation, you can enjoy a more comfortable indoor environment without the hassle of filter replacements or disruptive noise.

Lastly, we noticed that the unit generates some heat while in use, which might be a concern for sensitive individuals or during warm weather months. Despite this, we believe the Airfree Duo is a fantastic investment for those who value clean air and odor elimination without the constant expense and maintenance of filters.

Secondly, for those with severe allergies, the AIRFREE Lotus may not be as effective as other air purifiers with HEPA filters. Lastly, it can be challenging to measure its effectiveness as there is no tangible indication of the air quality within the room. The only way to know if it’s truly working is by gauging how you feel in the room over time.
In conclusion, the AIRFREE Lotus Filterless Silent Air Purifier is a great choice if you value a noiseless, low-maintenance air purifier with a distinctive design.

Upon using the Hamilton Beach TrueAir Air Purifier, we believe it’s a great value for those looking to improve the air quality in smaller spaces.
Pros
- 99% HEPA-grade filtration performance

One thing to note is that this air purifier is best suited for smaller spaces, as it can efficiently cover up to 160 sq ft. If you’re planning to use it in a larger area, you may need to consider multiple units or a more powerful purifier. However, for its size, it effectively captures 99% of allergens, dust, and pollen with its HEPA-grade filter.
A significant advantage of the Hamilton Beach TrueAir Air Purifier is its permanent filter, which can easily be vacuumed clean. This feature eliminates the need for recurring filter purchases, making it a cost-effective choice. That being said, we noticed that the white color option we chose came with grey trim, which may be a minor downside for those particular about the color aesthetic.
When it comes to noise levels, the air purifier remains relatively quiet on its “Whisper Clean” setting. However, on the highest setting, we found it to be noticeably louder. If you plan to use it during the night, the medium or lowest setting may be more suitable to avoid disturbance.
In conclusion, we highly recommend the Hamilton Beach TrueAir Air Purifier for those looking to improve air quality in smaller rooms. Its stylish design, high performance, and permanent filter make it not only a functional choice but an economical one as well.

Buying Guide
When it comes to finding the best filterless air purifier, there are several factors that you should consider to ensure that you make the right choice for your needs. In this buying guide, we will explore some of the key features and aspects you should look for in an air purifier.
Noise level
One of the first things you should consider is the noise level of the air purifier. You’ll likely be using this device in rooms where you spend a lot of time, so it’s important to make sure it operates quietly. Some purifiers can produce as little as 20-30 decibels (dB), which is similar to a whisper, while others can generate noise at levels upwards of 50 dB. Be sure to choose a product that won’t disrupt your peace and quiet.
Room Size
Next, consider the size of the room where you plan to use the air purifier. Filterless air purifiers have different coverage areas, and you’ll want to choose one capable of cleaning the air in your specific space. Measure the square footage of your room and look for a purifier that can handle that area.
Here are some general guidelines for room coverage:
| Room Size (sq. ft.) | Coverage Needed |
|---|---|
| 100-200 | Small |
| 200-400 | Medium |
| 400-600 | Large |
Energy Efficiency
Energy efficiency is an important aspect to consider, as it will affect the ongoing cost of using your air purifier. Look for products with ENERGY STAR ratings, which means they have been tested and meet certain standards for energy efficiency. This will help ensure that you are not only contributing to a cleaner environment but also keeping your energy bills as low as possible.
Maintenance and Cost
Since filterless air purifiers don’t require filter replacements, their overall maintenance is typically lower than traditional air purifiers. However, certain components like UV-C bulbs or collection plates might need occasional cleaning or replacement. It’s essential to understand the maintenance requirements and costs associated with the specific purifier you choose so you can be prepared to keep it running effectively.
Additional Features
Finally, consider any additional features you may want in an air purifier. Some devices come with timers, remote controls, or even smart features that integrate with your home automation system. While these features may not directly impact the device’s air purification performance, they can add convenience and functionality to your experience.
By keeping these factors in mind and thoroughly researching your options, you can confidently choose the best filterless air purifier for your needs.

Major advantages of filterless air purifiers include lower maintenance costs and less environmental waste. They don’t require filter replacement, which saves money and reduces waste from disposable filters. In addition, these devices are often quieter than their filtered counterparts, as they don’t rely on fans to circulate the air.
How do filterless air purifiers compare to HEPA purifiers?
Filterless air purifiers and HEPA purifiers both have their pros and cons.

Filterless purifiers, on the other hand, generally have lower maintenance costs but may be less effective at capturing ultrafine particles in some cases.
Are there any popular brands that manufacture filterless air purifiers?
Leading brands known for manufacturing filterless air purifiers include Airfree, Ionic Pro, Air Oasis, and Airocide. These brands offer various models designed to cater to different room sizes and specific needs, such as allergy relief or smoke removal.
