Filterless Air Purifier: What Is It and How Does It Work?

Filterless Air Purifier: What Is It and How Does It Work?

Wherever you are, whether you’re at work or at home, one of your primary concerns is to breathe in only the cleanest and freshest air. When you’re in an environment with clean air, you’re healthier, happier, and more productive. Purchasing and owning a filterless air purifier can definitely help you benefit from fresh air in your office or at home. Before you go out to buy one, learn more about what filterless air purifiers are and how they work. According to Cares Fresh, air purifiers without filters are a great way to clean the air in your home. They help get rid of things in the air that can make you sick or cause allergies.

What a Filterless Air Purifier Is

A filterless air purifier is a type of air purification machine that sanitizes a room by taking away the unhealthy particles and allergens present in the air. In particular, the filterless type is an ingenious technology in air purifiers as it works just as effectively as filtered air purifiers, except you save a lot of money because you don’t need to replace the filters every six to twelve months. High-efficiency particulate air (HEPA) filters can be quite costly, and certain brands may be hard to find replacements for.

Filterless air purifiers operate quietly even if you use them all day long. These purifiers don’t have built-in fans, so they don’t make unnecessary noise. They are ideal for use in bedrooms or nurseries. Moreover, these purifiers can take away strong odors, smoke, and toxic fumes. You can already stop using air fresheners because a good filterless purifier can already make your room smell clean and pure.

It’s very easy to care for and maintain filterless models. If you have a traditional HEPA-filter purifier, you have to clean the filters after a couple of months. Dirty filters will negatively affect the air quality in your home or office. With filterless purifiers, you don’t run the risk of contaminating the air you breathe and possibly triggering allergies. When you need to clean your filterless air purifier, you just need to use a damp cloth to wipe the collection blades.

On the downside, HEPA-filter purifiers and other air purifiers with high-tech types of filters do remove more toxic particles from the air as compared to filterless models. If you don’t have specific respiratory concerns, have no pets, or you live in a less polluted area, a filterless air purifier will already suffice to meet your needs.

What the Types of Filterless Air Purifiers Are and How They Work

If you’re considering a filterless purifier model for your home, there are several kinds of models that you may choose from:

Air Ionizers

The first type is the ionic air purifier. It makes use of two plates that are electrically charged, which work together to sanitize the air thoroughly. One plate charges all the molecules flowing in and out of the purifier. An electrical field within the purifier charges all the molecules and then releases the cleaned air back into your enclosed area.

The other plate works like a magnet to protect your room. Because of the second plate’s opposite charge, it stops dirty molecules and toxic substances by attracting these particles to itself. When these harmful particles are already trapped by the second plate, they can no longer contaminate the air in a room that’s already been purified.

An example of a popular model is the Envion Ionic Pro 90IP01TA01W Turbo Ionic Air Purifier, which can eliminate over 90% of harmful molecules present in the air, such as allergens and viruses. It’s also one of the best air purifiers at dealing with mold.

Electrostatic Precipitators

The second type is the electrostatic precipitator. It catches unhealthful molecules found in the air. If you open up an electrostatic precipitator, you’ll see a set of plates and wires inside that is energized by a high-voltage electrostatic field. The precipitator gives the air an electrical charge and takes away harmful airborne particles, and releases ions that sanitize the air that flows through it. Electrostatic precipitators are quite efficient at getting rid of dirty molecules in the air within an enclosed space.

Ultraviolet Purifiers

Another model is the ultraviolet air purifier. Ultraviolet light is very powerful and can eradicate microorganisms in enclosed areas. It can kill viruses, germs, bacteria, and mold spores. Certain brands of air purifiers now build in ultraviolet light into their devices. Not only are ultraviolet purifiers effective, they are also cost-efficient. They don’t consume a lot of electricity.


Clean air is critical to your health and well-being. It energizes you and can contribute to the efficient functioning of the different organs in your body. Fresh air will also uplift the mood and atmosphere in your home or office. Investing in a good filterless air purifier will be worth it for you and your loved ones.
