Air Purifier

Air purifier or air cleaner is known as device that eliminates impurities from the air in a space to enhance interior air quality. These devices are frequently advertised as being helpful to allergies and asthma patients, as well as decreasing or eradicating residual cigarette smoke.

Commercial air purifiers are available as tiny stand-alone units or bigger units that may be attached to an air handler unit (AHU) or an HVAC unit in the medical, industrial, and commercial industries. In industry, air purifiers can be used to eliminate contaminants from air before it is processed. This is usually done with pressure swing absorbers or other adsorption methods.

Benefits and applications

Portables with a high-efficiency HEPA filter and sized for the proper space may catch 99.97% of airborne particles,” says Joseph Allen, head of Harvard’s School of Public Health’s Healthy Buildings programme.

Possible ozone dangers

The claims of certain firms, as with other health-related products, are controversial, particularly when it comes to ionic air purifiers. Many air purifiers produce ozone, an energetic allotrope of three oxygen atoms, as well as modest quantities of NOx in the presence of humidity. Ionic air purifiers produce the most ozone due to the nature of the ionisation process. Because ozone is a criterion air pollutant controlled by health-related federal and state regulations in the United States, this is a severe problem.

Products and Services for Air purifier

Product Description:

Because you can’t see, feel or taste the air in your environment, you might not realise that it may not be clean. Unless you suffer from an allergy, you probably don’t even think about the air you breathe. Both outdoor and indoor air are really polluted but the fact is, outdoor air can be 5-100 times more polluted than indoor air, especially in the industrialised area (source: U.S. Environmental Protection Agency). Research indicates that people spend approximately 30% of their time outdoors, which means that exposure to outdoor air pollution can be a risky.

Everyone, to some extent. However, people spend 1/3rd of their time to outdoors are exposed to the harmful effects of outdoor air pollution. Such groups include the young, the elderly, or those suffering from respiratory ailments. Healthy people need to beware too, as the number of allergy sufferers dramatically increases with the level of air pollution. Today, one in three people suffers from an allergy.

The New England Journal of Medicine published research that found air pollution to be statistically linked to increased health problems (source: “Air Pollution and Health – Good News and Bad”, by C. Arden Pope, III, PhD). Particles 5 to .001 microns, including simple dust, Foundry Dust, Insecticide Dust¸ Cement Dust, Dust & Fumes, Coal Smoke, Atmospheric Dust, Resin Smoke, Carbon Black, Tobacco Smoke can pass through the nose and throat and go directly into the lungs. A hazardous particulate size less than 5 micron.

The air that we breathe every day indoors and outdoors may contain harmful gases and particles, including germs, viruses, dust, bacteria, pollen, mould spores, animal dander, smog, tobacco, smoke and soot. Ventilation is necessary, as it will bring in enough outside air to dilute emissions and flush air pollutants out of the home. If insufficiently evacuated, these gases and particles can lead to air quality problems. That is why we are offering ES 402 Air purifier which is the solution of above mentioned Problems.

The air purifier ES 402 was tested for its ability to reduce the number of micro ■■■■■ INHALEs aspired into a test room.

Pollutant-free air can reduce asthma and allergy symptoms as well as the need for medication. Using an air cleaner ES 402 offers relief by removing pollen, pet dander, tobacco smoke, mould spores, household dust, and dust mite allergens from the air.

The ES 402 Air Purifier is suitable for allergy and asthma sufferers, the patented surround seal technology allows optimal air flow and it is designed for maximum air intake. It filters the air at a rate of 99.999%which means that partials up to the size of .001 microns can be filter through it such as

Radioactive Fallout 0.1 – 10
Rosin Smoke 0.01 – 1
Combustion 0.01 - 0.1
Smoke from Natural Materials 0.01 - 0.1
Burning Wood 0.2 – 3
Coal Flue Gas 0.08 - 0.2
Oil Smoke 0.03 – 1
Tobacco Smoke 0.01 – 4
Viruses 0.005 - 0.3
Typical Atmospheric Dust 0.001 to 30
Pesticides & Herbicides 0.0015
Carbon Dioxide 0.001

There are four settings to meet required needs. A pre-filter (CP170PRE Amazon number B003UER1MI) with active carbons neutralises odours, while the HEPA filter (CP170HEP) works to capture the smaller particles and an electronic filter reminder lets you know when these need to be changed.

We are providing 5years warranty of ES 402.

Design for Air purifier:

HEPA filters are designed based on the size of particles to be removed and the required air flow rate. The finer the pores in the HEPA material, the finer the particles removed from the air. However, collecting finer particles means the filter material will clog sooner and need replacing on a more frequent basis. The designer will specify the diameter of the glass fibers and the mat density of the filter fabric that fixes the filter pore size. HEPA filters can contain binders that provide additional strength, but this also produces a filter that clogs sooner.

The unique SOP product is:

  • It is environmental friendly

  • It consumes Just 86 watts.

  • It also has solar panels so that it can run on solar energy in case any shortage of electricity.

  • Purifier air & Maintain the balance of particles and gases in the air by managing what component is needed in what proportion.

  • Eliminate excess of carbon component so that ozone layer gets less damage.

  • Filter partials up to 0.001 microns.

  • Provide clean air.

Sales Literature for Air purifier:

The target market for purifiers is vast, so we are focusing on market niche to become known for selling purifiers among them. We sell purifiers to people who need one for their homes or condominiums due to allergies or to people with new homes that contain lots of chemicals and toxins from the construction.

Another option is to sell purifiers to manufacturers that need to freshen the air in their plants. Selling purifiers to businesses that want to improve air quality is another option and to government who want clean environment and to NGO’s.

To supplement sales, we are offering filter replacements to keep generating revenue long after we sell the purifier itself. We also keep track of when each customer buys an air filter and send out a postcard reminding them about a month ahead of when it’s time to change the filter. Make easy for the customer to order new filters, in addition a promotional discount is also giving.

For promotion we use social networking such as Facebook, web sites, twitter etc. Except it we advertise our product through TV, channels, newspapers, magazines and on those public places where there is lot of people such as amusement parks etc. to call them to protect their environment, health.

Sourcing and Fulfilment for Air purifier:

The materials that go into it a case made out of plastic, an electric fan to induce air flow through the filter, the filter itself, and control switches to control the speed of the fan and turn the air purifier on and off borosilicate glass fibers or plastic fibers acrylic binder, post-filter composed of activated carbon, HEPA material.

Technology for Air purifier:

Following Technologies are used in Air purifier.


A pre-filter captures the largest particles before they reach the more expensive HEPA filter. Most of the particles in your air are large particles like dander and dust, not tiny ones like pollens and microbes. Even though HEPA filters have a large number of pleats to maximize their surface area, they can fill up quickly if larger particles are not pre-filtered out.

Activated Carbon:

Elements like activated carbon, zeolite, or potassium permanganate are added to air purifier filters to increase efficiency to the filtering system. These elements work to absorb smoke, gases, chemicals, and odors that are present in the air. Activated carbon neutralizes odors and traps harmful chemicals and gases in its pores to provide relief from activities like secondhand smoke, off-gassing from plastics, and harmful fumes produced from renovations. An effective filtering system that is also equipped with chemical adsorption materials can produce cleaner and fresher-smelling air.

Ultraviolet Light:

Ultraviolet light (UV) technology is key to neutralizing viruses and bacteria that accumulate on air purifier air filters. It is important to use the UV technology in combination with HEPA air filters and possibly activated carbon. Without a particulate filter system like a HEPA air filter, too many micro ■■■■■ INHALES may be hidden from the UV light, since it is not easily located on an air filter.

Industry Analysis:

Air quality products are a category that includes humidifiers, air purifiers, and dehumidifiers for household or industries use. These products are created to change the quality of indoor air in an individual room or within an area inside a house. They are normally small so they can be efficiently moved, and do not require installation and very little maintenance.

Due to less consumer knowledge of, an interest in, better air quality, there is a low opportunity for manufacturers and companies to position air quality items as must-have products, equally as important as irons and vacuums, so far. Manufacturers are presently creating new ideas in the area of items that do not leave unwanted pollutants like a bad ozone. Air purifiers that have high-efficiency particulate air (HEPA), do not leave bad ozone in the air, which can increase symptoms of allergies.

Air quality items are getting huge traction and demand from Easter-influences complementary and alternative medicine (CAM). CAM encompasses a large spectrum of therapies, treatments, and health-systems --both ancient and new-- that can be normally identified as health and wellness practices falling outside of the spectrum of normal Western medicine and Western consumer habits. The air quality products market has many major companies, with no individual firm dominating the market.

The Association of Home Appliance Manufacturers (AHAM) single handily lists off more than 4 brands of air cleaners that have gone through certification through its Room Air Cleaner Certification Program. Humidifier and dehumidifier manufacturers are just as many and divided. Air quality product marketers mostly lie in two categories: small private companies with limited items and distribution, and large innovators with many product lines, including home appliances.

Industry Participants:
  • Speed shops: Sometime part time venture run by individuals. They usually carry minimal amount of inventory and usually operated by solely upon small circle of friends and acquaintance. They normally short on marketing skills.

  • Manufacturer & Suppliers: typically, they are main manufacturers and leading suppliers who has capture main chunk of the market. They provide superb technical support.

Frequently Asked Questions (FAQs)

Following are some questions which are frequently asked by people:

Q1 Are air purifiers genuinely beneficial to your health?

The end result. Filtering the air can help eliminate dangerous particles from interior environments, such as allergies, smoke, and mold, according to research. Still, air purifiers are most effective when used in conjunction with adequate filtration and cleaning practices in the house.

Q2 Why are air purifiers harmful to your health?

Throat discomfort, coughing, chest pain, and shortness of breath, as well as an increased risk of respiratory infections, are all possible side effects. Some ozone air purifiers are also equipped with an ion generator, sometimes known as an ionizer. Ionizers can also be purchased separately.

Q3 Is it a waste of money to buy an air purifier?

As a result, it’s understandable if you’re questioning if air purifiers are a waste of money. According to the EPA, they’re worth it since they’re a great method to improve the indoor air quality of your Kearney home.

Q4 Is it beneficial to sleep with an air purifier on?

Air purifiers enhance indoor air quality, which can help you sleep better by reducing lung, eye, and skin irritation. Dust, smoke, and allergies or irritants are examples of this. An air purifier can also help to eliminate smells, resulting in a peaceful evening atmosphere conducive to restful sleep.

Q5 Is Covid filtered by air purifiers?

Air cleaners and HVAC filters, when used appropriately, can help minimise airborne pollutants such as viruses in a building or small area. Cleaning or filtration of the air alone is insufficient to protect individuals from the effects of pollution. COVID-19

Q6 What are the drawbacks of using an air purifier?

The following are some of the drawbacks of air purifiers:

  • You must keep the windows shut.

  • Maintenance is required on a regular basis.

  • Air quality is harmed by old filters.

  • An air purifier requires a clear area around it.

  • Air purifiers aren’t completely silent.

  • Production of ozone.

  • It isn’t a panacea for all issues with indoor air quality.

Q7 What’s the greatest spot for an air purifier?

Keeping your purifier near a window or a doorway is usually the best option. Another reason to locate purifiers in high-traffic areas is that moving air has enough force to remove dust, mould, and a variety of other particles, which it may subsequently disperse throughout your home.

Q8 Do air purifiers boost oxygen levels?

Air purifiers are intended to purify the air within your home so that you and your family may breathe comfortably.
Some purifiers also absorb oxygen from the air, but this has no effect on the amount of oxygen you breathe. The quantity of oxygen in the air is not reduced by air cleaners.

Q9 Is it true that air purifiers emit radiation?

The amount of radiation emitted by air purifiers is determined by how they operate. They also produce ozone and have greater radiation levels, so they aren’t ideal for use at home.

Q10 Do I need an air purifier if I have air conditioning?

Because air conditioning is poor against dust and pollen, it has nothing to do with air cleansing. Air purifiers are required in rooms with air conditioning more than in other rooms since the same air circulates and can only be cleansed by using an air purifier.

Q11 Is it true that an air filter removes dust?

Although an air purifier cannot entirely eliminate particles, it may significantly reduce home dust with frequent usage. This means less dust in the air, fewer cleaning tasks, and healthier, cleaner air around your house.


An air purifier, also known as an air cleaner, is a device that removes contaminants from the air in a room to improve the quality of the air inside it. These devices are usually touted as being beneficial to those with allergies and asthma, as well as reducing or eliminating residual cigarette smoke.

In the medical, industrial, and commercial industries, commercial air purifiers are available as small stand-alone devices or larger units that may be coupled to an air handler unit (AHU) or an HVAC unit. Air purifiers can be used in industry to remove impurities from the air before it is treated. Pressure swing absorbers or other adsorption mechanisms are commonly used for this.

According to Joseph Allen, director of Harvard’s School of Public Health’s Healthy Buildings programme, “portables with a high-efficiency HEPA filter and scaled for the correct area may trap 99.97 percent of airborne particles.”
