How to Choose the Right Filterless Air Purifier – Buying Guide
When it comes to buying the perfect filterless air purifier, the experience is a little different than purchasing an air purifier with the filter.
There are several things that you need to think about, when buying the best air purifier without filter.
Maximum Area Coverage/ Range
The first consideration is the coverage area of the unit. The effectiveness of air purification unit is based on the square footage of the room. Measure the room of the size you want to appear by. Popular rooms for air purifier include bedrooms, kitchens, living rooms and home offices. Make sure that the unit will be able to support the space where you’ll put it.
Choose the model with coverage rating slightly higher than your intended room size.
Also, consider the noise level. This is important if your air purification unit is working in a bedroom or office where noise will be a concern. For a very quiet air purifier look for one marked 15 decibels or less.
The weight of an air purifier unit affects to its mobility. If you need to move the unit around, to different places of your home, choose the model that will give you a lot of versatility. However, a filterless unit isn’t heavier than 10 pounds. But 3 to 7 pounds is ideal for a lightweight air purifier.
Today’s air purification units come with various advanced features that may be an important consideration for you in considering the right model. Features such as multiple speeds, a remote control, air quality sensor, auto shut-off and so on. Remote control can be convenient for changing the settings across the room. Handles will allow for greater flexibility if you need to move the unit around the house. Wi-fi connectivity is an excellent option for monitoring and adjusting your air purification unit on the go.
To remove pesky airborne pollutants, select the model that is capable of removing at least 99% of airborne particles.
Most air purifier ranges from $50 to 600+. The most significant factors in determining the price are purifier’s coverage range, type of purification, and features. However, keep in mind that models with fancy features will cost you a lot.
What is a filterless air purifier?
In general, air purification systems use different types of filters to capture the various elements that are in the air. Undoubtedly, these filters are handy. But they are costly, requires regular cleaning, replacement and maintenance. However, a filterless unit minimizes those hassles of filters.
A filterless air purifier is a device that purifies the air without the need for a filter. They use different types of purification methods to make your air clean, fresh and healthy.
How No filter system Works
As the name suggests, there is no physical filter in a filterless system to purify the air. It uses simple technologies other than filters to remove the airborne particles.
There are different methods that no filter air purifiers use for the purification process. Some of these methods are:
- The ionization method
- The Electrostatic precipitation
- Heat sterilization/Thermodynamics method
- Ozone generation
- UV-C rays method
- Photocatalytic oxidation
Most of the airborne particles and germs are consisted of positively charges ions. The unit that uses ionization technology produces a steady stream of negatively charged ions.
These negatively charge ions attract the positive ions of airborne contaminants and form an ionic bond. When they clasped together, the particle’s cluster becomes very heavy. As a result, they can’t remain in the air and settle in the device.
In the thermodynamics method, the power of heat is used to remove microorganisms and germs from the air. It just passes the air through very high temperature (400- degree Fahrenheit) to kill microorganisms present in the air. Thus, they give you a healthy living or working environment.
Some units of this category use the power of UV-C light to eradicate the harmful contaminants of air.
Filterless air purifiers offer a wide variety of different benefits.
Some of the most outstanding benefits of using a filterless air purifier follow here in short.
They don’t require much maintenance
The excellent and most lucrative benefits are the users don’t need to spend extra money on replacing the filter after some months or years. Additionally, as there is no filter, there is no pain of cleaning the filter stinks.

Best filter free air purifiers don’t produce much noise. And there is no fan in the filterless units. So, you won’t need to deal with a lot of noise. If you’re very sensitive to noise, then you’ll probably appreciate this quietness. The noiseless operation is one of the most significant benefits of no filter unit over a true HEPA air purifier.
They are energy efficient
There is no fan in a filterless system. With fewer components to power, it uses less electricity than any filtered counterparts.
They don’t dry out the indoor air.
Users of air purifier with filter complain that they wake up with sore throats in the morning. But this is not the case for filter-free units. A filterless unit purifies the air without significantly change the humidity to its surroundings. So, you don’t need to worry about the indoor dry air and sore throat when running a filterless system in your bedroom.
Moreover, filterless units are lighter, portable. They are also cheaper than filter type air purifier.
Nothing is an unmixed blessing in the world, and so everything has few or more shortcomings. Same is the case with the filterless units.
Here follow some of its’ significant demerits.
Less effective compared to HEPA air purifiers
Most of the filterless purifiers are not as capable as HEPA filters. The reason is- the inbuilt plates for attracting harmful invisible particles are not so much active. Moreover, the machine becomes weaker when a mass of dirt accumulates on the plates.
Less effective against odors
The filterless systems are less effective in removing odors as compared to air purifiers having carbon filters. However, ozone-generation filterless air purifier is effective in elimination odors, smoke from the air.
Seen to release Ozone
Ozone-generation filterless air purification systems are often seen to release Ozone that is harmful to a human body.
How do I choose the right air purification system with perfect coverage?
Always pick a model that will exceed the square footage size of your room size. If your intended room size is 400 square feet, opt for a model rated with 500 square feet coverage.
How do I find out the square footage of my room?
It’s simple! To calculate the total size, you need to measure the length and width of your room in feet. Round up the data if needed. Then multiply these two measurements, it’ll give you the total square footage.
Length 30 ft. x Width 15 ft.= total 450 square feet.
Do the purifiers that use ionization method to purify the air kill germs?
Yes, the ions that they produce can reduce or kill bacteria.
Are the UV-C lights inside the filter-free air purification unit safe for humans?
Yes, the UV-C rays that are used in this type of air purification system feature band of the electromagnetic spectrum of 400 nm to 10 nm. This length is shorter than the visible light and longer than X-rays. It kills microorganism of air without impacting human health.
Is it safe to keep air purifier on at all times?
No problem. You can keep your air purifier on 24 hours/ day, 7 days/ week. If you turn off the unit, the chances are that the microorganism may start to build up again. So, it’s recommended to keep your unit on all the time to keep virus and bacteria under control.
Is it safe to use a filterless system that doesn’t have an ACH rating (Air Changes per Hour)?
ACH refers to per hour how many times an air purifier completely exchanges the air in a room. This rating is applicable only for filter type air purifier that has fans to suck in contaminated air.
A filterless unit doesn’t employ a fan to blow out the clean air. So, you don’t need to consider the ACH rating for a filterless unit.
Does an air ionizer purifier remove odor from the air?
Ionizer air purifier units effectively eradicate common household odors from chemical cleaning agents, smoke, pets, cooking, and mold.
