What does an air purifier do?

Before we talk about how to choose a better air purifier for home, you should know the basic working function about that.

- How the air purifier work?

The technology behind air purifiers is actually quite basic—it is essentially a fan blowing air through a filter (which, in fact, is how the majority of the most effective air purifiers in the market work). But the technology can also go beyond this basic setup. Some air purifiers also use electric ions, carbon adsorption or photochemical reactions to remove or even destroy particles and gaseous toxins in the air.

It is also true that some types of air purifiers are not as effective as others. Nevertheless, studies have found that a good air purifier can effectively improve air quality.
This is why it is imperative that you purchase the right kind of purifier that will most effectively address your specific air quality issues. We will take a look at how air purifiers work to remove pollutants from the air and what scientific research says about their effectiveness.

Air purifiers with different functions will also be equipped with a negative ion generator at the air outlet (the high voltage in the negative ion generator generates DC negative high voltage during operation), which continuously ionizes the air to generate a large number of negative ions, which are sent out by the micro fan to form a negative ion airflow. To achieve the purpose of cleaning and purifying the air.

1. Purification principle of passive adsorption filter type (filter purification type):

The main principle of the passive air purifier is: the air is drawn into the machine with a fan, and the air is filtered through the built-in filter, which can filter dust, odor, toxic gas and kill some bacteria. The filter is mainly divided into: particulate filter and organic filter. Pieces
The particulate filter is divided into coarse filter and fine particulate filter. 

2. The principle of active purification (no filter type):

The fundamental difference between the principle of active air purifier and the principle of passive air purification is that active air purifiers get rid of the restrictions of fans and filters, instead of passively waiting for indoor air to be drawn into the purifier for filtering and purification. Instead, it effectively and actively releases the purification and sterilization factors into the air, and through the characteristics of air diffusion, it reaches all corners of the room to purify the air without dead ends.

- What’s the benefit for an air purifier for home

Reduce smell and odors
If your home or the surrounding area smells or odors, investing in an air purifier could be part of a long term solution to the problem. Odors can easily engulf your indoor air due to cooking, water damage, and flooding. If left unsettled, water damage can create a perfect breeding ground for potentially dangerous mold to grow. An efficient air purifier will filter your air and eliminate nauseating odors and mold spores, leaving you with clean air to inhale.

Cleaner Air
The first benefit of an air purifier is simply to improve the overall cleanliness of your indoor air by removing contaminants. Considering that the EPA estimates indoor air can be 2 to 5 times dirtier than outdoor air, this is naturally very important.

Protect you against dangers of outdoors pollution
Studies have shown that air purifiers with HEPA filters reduce the outdoor air pollution that comes inside of your home, by 23%. This means that air purifiers also reduce your chances of being affected by air pollution and its related health-problems (like cancer, respiratory diseases, kidney problems...)

Types of air purifier

The dust and pollutants in life are everywhere. Whether you work in a company or go shopping, bacteria in the air are always lurking around with micro-molecules. To better improve the air quality in our lives, you need to consider the functionality of various air purifiers in different application.

- Air purifier for dust

#Why you should care about dust in the air?

 Dust, you will come to see, is more than just bits of soil from the outside, but is composed of a hodgepodge of unexpected materials. You would be amazed to find where dust sacomes from. Dust can irritate your eyes, nose, or throat and be a problem especially if you have allergies, asthma or other respiratory illnesses. [2] If your asthma or allergies become worse because of dust, you probably have a dust allergy. What is worrisome for everyone is that tiny dust particles often float in the air, and if the particles are small enough, they can enter the lungs and cause health problems.

#How the air purifier can help you ?

What is dust anyway? This stuff is everywhere, sitting atop our furniture, sewn into the upholsteries of our recliners and couches, and making its way through our air, up our noses, and into our lungs. Domestically speaking, dust is an amalgam of everything from pollen to paper fibers, animal hair to dead skin cells. The particulate sizes of these elements rage from .001 to 1000 microns, leading many to wonder.

Though some particulates in dust such as atmospheric dust can be as small as .001 microns, the allergens and contaminants that make up the most harmful and abundant particulates like pollen (>10 microns), bacteria (> .3 microns), dander (>5 microns), even asbestos (> .7 microns) have large enough particle sizes to easily be trapped and contained by the powers of true HEPA air filtration systems.

Many modern air filtration systems, like Kloudic HEPA air purifier, come standard with air quality indicators which will sense when dust is being kicked up, whether during heavy traffic or cleaning, and can automatically adjust their fan speeds to filter air more quickly during instances of bad air quality.

- Portable air purifier

As the global epidemic worsens this year, more and more people are concerned about the air quality. In addition to buying a house air purifiers at room, the demand for portable air purifiers is also increasing. In order to be more convenient, many people choose portable air purifiers so that they can enjoy a high-quality air wherever they go.

Before you buy a portable air purifier for home, you may need to consider with several questions like:

Filter quality:

Only consider products that contain a real HEPA filter and an activated carbon filter. The HEPA filter captures particulates while the carbon filter removes odors and gases.


How large of an area do you need to filter? If you just need to purify the air in a bedroom, don't overspend on a product that's too big. But if you're trying to improve IAQ for an entire level of your home, you need to find a purifier that's capable of doing so.[3]

Why people will buy a portable air purifiers?

1. Unique appearance design, miniature wearable.
2. Portable air purifier has a small and unique design, which is convenient to carry around. You can put it in your pocket, car, kitchen, office, etc., or even as a pendant, healthy and fashionable.

3.It can quickly absorb the surrounding second-hand smoke, cooking fume, dust, etc., make sure you are always in a clean air.

4. With ultra-quiet design, it can quietly filter out bacteria and allergens in the air to ensure healthy breathing, which can be used at night and sleep more comfortable.

-Home air purifier for smokers

Wood-burning fireplaces, tobacco products, candles, cooking accidents, and other sources of smoke may be polluting your indoor air. Smoky air can irritate the eyes, sinuses, and throat, which might seem like only passing discomfort, but the effects add up. Thus, you need an air purifier to build a clean and health air indoor for you. It can help minimize adverse side effects and benefit your health.

What to Consider When Choosing the Air Purifier for Home smokers

The best home air purifiers use mechanical HEPA filtration to remove larger unwanted particles combined with activated carbon filtration, which targets smaller pollutants.
HEPA filters are made from interwoven glass fibers that create a barrier maze. As air travels through the filter, particles are removed from circulation by either direct impact, sieving, interception, or diffusion.
Kloudic Fliter
HEPA is a designation used to describe mechanical air filters that trap 99.97 percent of particles that are between 0.3 and 10 microns. This is the particle size most likely to escape filtration in non-HEPA systems, including pet dander, pollen, and dust mites. HEPA also removes the contaminants found in visible smoke including those emitted by wildfires, cigarette smoke, and cooking. It’s important to note that not all HEPA filters are created equal, since manufacturers can produce their own. Medical-grade HEPA filters are the most efficient.

Room Size
Air purifiers are labeled for specific room sizes, which are described in square feet. You can calculate square footage of a room by multiplying the length times the width. If you’d like to buy one air purifier to handle multiple rooms, add up the square footage for each room.

EPA Rating
Energy Star is a joint program of the Environmental Protection Agency (EPA) and the Department of Energy (DOE). The program’s goal is to help customers, businesses, and industries save money and protect the environment using energy-efficient products and practices.

Air purifier vs humidifier

Air purifiers and humidifiers can both impact the air you breathe in your home, but both of them are quite different in working function, so we also list several point for what you need to know for choosing a humidifier or an air purifiers for home.

What’s the different between air purifier and humidifier?

An air purifier is used to clean the air by removing or otherwise “inactivating” pollutants from the air. The two basic components of an air purifier are a fan and a filter surface, though the specific filtration technology can vary, from traditional HEPA filters to ionizers to brand-new PECO technology. In most air purifiers, air is passed through the unit, pollutants are trapped or removed on a filter and clean air is emitted back into the room. Air purifiers do not add any moisture to the air.[4]

A humidifier, on the other hand, does not clean the air. It simply adds water to the air by boiling water into steam, vibrating water droplets into the air with ultrasonic technology, or by evaporating the water using a fan and a wick.

Air purifier vs humidifier, which works better for different conditions?

For baby –
A humidifier can be better in the nursery if the main problem is dry air, and as mentioned above they can prevent dry, scratchy nose and throat. The FDA states that using a cool mist humidifier may help infants who have cough and cold symptoms, by shrinking nasal passages and helping them breathe easier. However, a warm mist humidifier should not be used, as it can have the opposite effect by causing nasal passages to swell, making breathing more difficult. When humidifiers are used to maintain an ideal relative humidity of 40 to 60 percent, they can also reduce the infectiousness of bacteria and viruses.
For allergens –
An air purifier can help reduce allergens levels in the air. A unit with a HEPA filter can help trap particles. Though humidifiers may help soothe a stuffy nose or other irritation, they can actually make allergies worse because higher humidity improves the survival rates of dust mites.[5]

For asthma –
A humidifier can ease asthma symptoms if dry air is also a problem, but it does not affect asthma itself, and higher humidity levels are actually associated with asthma attacks because they can trigger the growth of harmful bacteria, dust mites and mold . Since asthma attacks are often triggered by pollutants in the air, an air purifier that can remove those pollutants is better for asthma.

What other ways to improve the air quality in your room?

# Keep your sheets and clothes clean
Dust mites are a leading cause of poor air quality. They can irritate your nose and throat leaving you feeling tired and lethargic.
Dust mites can often linger in the fabric of your homes such as bedding, cushions, and curtains. It is important that you clean these items regularly in low allergenic washing soap.
If you have pets ensure that they keep off your bed and sofas to minimize the build-up of hair.
# Keep your windows open
Keep your windows open when it's safe to do so to prevent locking irritants into rooms (especially when air purifiers aren’t running!). Create a stronger cross draft by opening windows on opposite sides of the room if possible.

# Change the filters
If you have a forced-air heating system, it's important to change the filters on a regular basis. Additionally, use a high-performance air filter that can help capture and trap even small particles and allergens–like pet dander, smoke, dust and viruses.

# Invest in an air purifier.
Of couse, using an air purifiers is another effective way to tackle stale indoor air. You can place them in commonly used rooms, like in the living room, kitchen and bedrooms, to help ventilate and clean the air in these spaces.


The rising levels of outdoor air pollution, spurred by factors like vehicle emissions, fossil fuel burning, and industrial exhaust gases, is worrying enough to make you want to stay indoors as much as possible. But surprisingly, even the indoor air isn't exactly as clean and healthy as we'd like to believe. Thus, you need an air purifier to build a healthy and clean living room.

In this article, we’re talking about what is an air purifier does and how it works, you can learn the based working function of an air purifier and get the benefit from how an air purifier can do help our health. Before you choose or buy an air purifier for your home, you may also need to consider the different applications in a situation. For baby using, for the home smoker, or even for a more convenient lifestyle,you need a portable air purifier.

However, there are also some differences between home air purifier and humidifier, if you can learn more pros and cons between them, you can make a better choice easier. At the end of the blog, we’d like to share more other ways to improve your indoor air quality!
