AIR PURIFIERS (OZONIER AND PECO)

Today there are lot of air purifier depending upon different principles. Most of the purifiers depend upon tradional method 'HEPA'. But now technology is changing and also purifiers that now even purifies air at micro level. Two of the principles on which these purifiers work are 'PECO' and 'Ozonier'.

HEPA


This is now a tradional method to purify air. HEPA stands for high-efficiency particulate air. A HEPA filter is a type of mechanical air filter; it works by forcing air through a fine mesh that traps harmful particles such as pollen, pet dander, dust mites, and tobacco smoke. You can find HEPA filters in most air purifiers.

OZONIER

Used to purify air

It is a type of air purifier that uses ozone to kill bacteria. Ozone is a naturally occuring gas. A molecule of ozone has three oxygen atm. Ozone layer shields Earth from the harmful ultraviolet rays of the sun, it is pollutant at ground level.
However when used in right amount, ozone can purifies the air.

An ozonier is a device that generate ozone by charging the air with high voltage electricity. The gas is then released in air. Ozone improves air quality by removing unpleasant odours and killing microbes.

This is also used to sanitize food and drinking water without hurting their nutritional content.

On the flip side, some scientific studies suggest ozone can be harmful for humans and hence it should be used in care.

 PECO


Today the new, best and safe concept of air purify is PECO. Photo Electrochemical Oxidation (PECO), works at the molecular level to eliminate indoor air pollution.

Developed over two decades by research scientists, PECO is an innovative technology that utilizes free radicals—the same radicals used to kill cancer cells—to oxidize pollutants.

By using nanotechnology, PECO is able to destroy pollutants 1000 times smaller than traditional HEPA filters (0.1 nanometers versus 300 nanometers). With the help of this engineers made a purifier known as MOLEKULE


STEP1. Air Intake
It intake air from every corner
STEP2. Pre Filter
The air is circulated through the pre filter, trapping larger allergens like dust, pollen and dander.
STEP3. Nano Filter
PECO at work. A chemical reaction is created when a nanoparticle-coated filter is activated by light, breaking down harmful pollutant to their most basic molecular components.
STEP4. Pure Air
Molekule disperses harmless molecules that are meant to be in air, leaving your home pollution free in minutes.


The standard on the basis purifiers are tested is CADR


CADR stands for Clean Air Delivery Rate. This lets you identify how quickly the air purifier functions. It calculates how many cubic feet of air the purifier can filter in one minute. Higher the CADR number, better the air filtration. Air purifiers consist of three CADR numbers for dust, pollen and smoke.

What is Nebula. Images of some nebula by Hubble

A nebula is a giant cloud of dust and gas in space. Some nebulae (more than one nebula) come from the gas and dust thrown out by the explosion of a dying star, such as a supernova. Other nebulae are regions where new stars are beginning to form. For this reason, some nebulae are called "star nurseries." How do stars form in a nebula? Nebulae are made of dust and gases—mostly hydrogen and helium. The dust and gases in a nebula are very spread out, but gravity can slowly begin to pull together clumps of dust and gas. As these clumps get bigger and bigger, their gravity gets stronger and stronger. Eventually, the clump of dust and gas gets so big that it collapses from its own gravity. The collapse causes the material at the center of the cloud to heat up-and this hot core is the beginning of a star. Some of the most amazing nebula pictured by Hubble in Milky Way Galaxy The Eagle Nebula’s Pillars of Creation (M 16, Messier 16) The dust and gas in the pi...

25 June 1975 BLACK DAY FOR INDIA (EMERGENCY)

25 June which is considered as black day for india. It was 25 June 1975 when Prime Minister Shri Indri Gandhi declared Emergency through radio in India. In India, "the Emergency" refers to a 21-month period from 1975 to 1977, Officially issued by President Fakhruddin Ali Ahmed under Article 352 of the Constitution, the Emergency was in effect from 25 June 1975 until its withdrawal on 21 March 1977. The order bestowed upon the Prime Minister the authority to rule by decree, allowing elections to be suspended and civil liberties to be curbed. For much of the Emergency, most of Gandhi's political opponents were imprisoned and the press was censored. Several other human rights violations were reported from the time, including a forced mass-sterilization campaign spearheaded by Sanjay Gandhi, the Prime Minister's son. RESION BEHIND EMERGENCY On 12 June 1975, Justice Jagmohanlal Sinha of the Allahabad High Court found the prime minister guilty on the charge of...

Spiral Galaxy Images taken by Hubble Telescope

This is the Andromeda galaxy — otherwise known as M31. This is the neighbouring galaxy of Milky way galaxy (our own galaxy). This is nearly 2 million light years away from earth. This is a NGC 7640 i. e. barred spiral type galaxy. These are recognisable by their spiral arms, which fan out not from a circular core, but from an elongated bar cutting through the galaxy’s centre. This is the part of Andromeda constellation. This is the image of the beautiful barred spiral galaxy NGC 1300.  NGC 1300 is considered to be prototypical of barred spiral galaxies. Barred spirals differ from normal spiral galaxies in that the arms of the galaxy do not spiral all the way into the center, but are connected to the two ends of a straight bar of stars containing the nucleus at its center. This 60 million light years away from the earth and belong to the Eridanus Constellation. This is spiral galaxy Messier 77 — a galaxy in the constellation of Cetus, some 45 million light-y...
