What is an air purifier?
An air purifier is a device which purifies indoor air and give you back pure and fresh air. It works on two technologies -
  • It cleans air
  • It generates negative ions.
Why do we need an air purifier?

You must be aware that the AIR inside your office and residences, is very heavily polluted and every year, the health of many people is affected by the virus, bacteria, smog, pollen, allergens, chemical substances and harmful gases etc that is present in the air.

WHO has rated India on the top amongst the worst air pollution environments across the globe.

There have been many reports in recent times from organizations such as WHO and other environmental agencies over the alarming AIR POLLUTION levels in the city, and the air outside is polluted is only increasing the risk of problems of Indoor Air Pollution as it is roughly 40-50 times more polluted due to repeated air rotation in confined spaces. The problems to your health can be: Asthma, COPD Upper respiratory infections such as bronchitis and pneumonia. Lower respiratory problems in Children Ischaemic heart diseases Irritation to the eyes, nose, throat Headache, nausea, and allergic reactions.

In the long-term it can effect and give chronic respiratory diseases such as lung cancer Hence in order to get rid of all the diseases, related to polluted air, fresh air is very important for us!! So we propose using the BEST AIR PURIFIER in India, made for India, developed by India, CRUSADERS AIR PURIFIER.

What causes indoor air pollution?
Indoor air pollution is caused by inadequately ventilation .All kinds of contaminants in your home like pollen that blows in when a door or window is opened, pet dander that hitches a ride on clothing, or chemicals and irritants released by cleaners and perfumes. Pollutants like tobacco smoke, pollen, mold, dust can cause asthmatic and allergic reactions, making homes unpleasant and unhealthy especially for allergy and asthma sufferers. Other contaminants, like chemically reactive gases can cause allergic reactions and more serious health problems.
What are the benefits of Air Purifiers?
As we all are aware that air pollution is increasing at an alarming rate and with it our body is becoming more prone to diseases like watery eyes, puffing, sneezing, allergies, respiratory irritations or breathing difficulties, asthma and various allergies. In order to get rid off all these diseases related to polluted air, fresh air is very important to us. With the good quality of fresh air, it will increase your immune system, body metabolism and blood circulatory system and thus make you less prone to diseases. And you can lead a healthy life. Since prevention is better than cure.
How does it works?
It works with the help of 7 layers of purification.
  • Pre Filter
  • Plasma Filter
  • Activated Carbon Filter
  • HEPA Filter
  • TiO2 Filter
  • UV Filter
  • Negative Ions Generator
What is a Pre Filter?
The air first enters the pre filter. Its main function is to capture large particles such as dust, pollens, skin flakes. Another feature of this filter is to preserve and extend the life of other filters.
What is an electrostatic or plasma filter?
Electrostatic filters use an electrostatic charge to attract pollutants and trap them on collector plates. It helps in removing fine dust particles, dust mites, pollens etc.
How does plasma filter works?
The air first enters the air purifier and the particles in the air are charged using high voltage wires. The charged particles are then pulled in to metal plates that are charged oppositely. The static that is developed by the machine attach are charged to all particles in the air that is taken in by air purifier. The opposite charge is placed on to collection plates or other types of medium inside the air purifier. This medium attracts the charge particles and they stick to the charge mediums instead in the air.
What is an activated carbon filter?
This particular filter specialize in capturing and neutralizing common chemicals, gases, odors and tobacco smoke.
How does carbon filter works?
The carbon atoms present in this charcoal gets highly activated and this activated carbon has been treated with oxygen, opening up millions of pores in the carbon. There are so many of these tiny pores that one pound of activated carbon has a surface area of 60 to 150 acres. This huge surface area makes it ideal for adsorbing gases and odors. These chemicals and gases are too small to be trapped by a HEPA filter, but they bond to the enormous surface area in the activated carbon. The bigger the carbon filter, the more chemicals it will be able to adsorb and the longer it will keep on working.

What is carbon filter made of?
It is made of charcoal.
What is a HEPA filter?
HEPA stands for High Efficiency Particulate Air. HEPA filter removes at least 99.97% of all particles as small as 0.3 microns
How do HEPA air purifiers work?
A HEPA filter removes at least 99.97% of all particles as small as 0.3 microns. HEPA were originally developed by the Atomic Energy Commission to capture radioactive dust particles. Allergens such as pollen, animal dander, mold spores, and dust get trapped in the filter. This contaminates and particles are not able to flow back into the circulation due to high absorbent pores of the HEPA.
What is HEPA made of?
HEPA filter is made up of glass fibres with very tiny passage that allows the air flow to pass through the material but not much else. Since the passage through the fibres of the media are so small, you need a lot of surface area for a reasonable amount of air flow to pass through the media. Therefore, this media is always folded in an accordion or zig-zag fashion to get a lot of surface area.
What is TiO2 filter?
It is Titanium dioxide. Titanium dioxide, also known as titanium(IV) oxide or titania, is the naturally occurring oxide of titanium, chemical formula TiO2. It is also known as photocatalytic oxidation.
How does it works?
It works on 3 methods-
  • Deodorization : it deodorizes the odors from tobacco and garbage, aldehyde, ammonia, mercaption, chloroform, p-dichlorobenzene, gasoline, strong smell of paint and many more.
  • Neutralization : it breaks down NOx, SOx, CO compounds, formaldehyde etc. and neutralizes them.
  • Sterilization : it sterilizes areas of bacteria, fungus, mold, duckweed, pest infestation etc. it also reduce the growth of micro biological organism.
What is UV light?
It is the most effective way to destroy micro organisms such as germs, virus, fungi, bacteria. It also destroys the microorganisms that are trapped by HEPA filter preventing them from reproducing and recirculating through the room.
What are negative ions?
Negative ions are basically negative charged particles. Negative Ions help purify and freshen the air you breathe silently, optimally, and safely. It eliminates pollen, mold spores, dust, pet dander, and many other allergy causing particulates from the air you breathe. It circulates trillions of negative ions to neutralize floating pollutants through out the room.
What are the benefits of negative ions?
It helps increasing the blood holding capacity in the body, body metabolism, respiratory system and make the environment more favourable.
What is a micron?
Air purifiers are designed to eliminate impurities in the air—even those impurities which are so microscopic that they are invisible to the naked eye. Microns are used to measure the size of these microscopic airborne particles. Microns are used to measure airborne particle sizes. One micron is 1/25,000 of an inch. To give you an idea of how small this is, dust mites average around 300 microns, and a grain of sand can be over 800 microns!
Should air purifier be run all the time?
We recommend that you run your air purifier continuously for optimum operation.
How loud are air purifiers?
There are flow button on the LCD display of air purifier. With the help of these buttons you can set the flow according to your convinient.
Will the air purifier clean the air of whole house?
No, a single air purifier will not clean the air in your entire house. Even “whole house” systems will not effectively clean the air in your entire house. The bedroom is the most important room in terms of air quality, since you spend most of your time there. If you spend a great deal of time watching TV, you may need an air purifier for your TV room. If you don’t spend much time in certain rooms, you probably don’t need an air purifier in them. No, a single air purifier will not clean the air in your entire house.

Where should I put my air purifier?
If you suffer from allergies (especially if you’re allergic to dust), then the best place for an air purifier is your bedroom. It’s essential to have clean air in your bedroom because you spend about a third of your life there.
