Do you remove the harmful bacteria and pollutants floating in the interiors of your car? Actually, you cannot see and remove all of them. But the car purifier does.

Why should I buy a car air purifier?

  • A Car air purifier helps to create negative ions

A car purifier is a small device that emits millions of negative ions into the atmosphere of your car.

When it comes to ions, negative is a positive thing! Yes, that’s right! Negative ions latch onto the millions of invisible dust and smoke particles inside your car and drop them to the floor! As a result, you and your family members never have to breathe toxic substances.

  • Car air purifier eliminates harmful substances

Due to massive industrialization and the population explosion, you have simply bought a car and believed that is all that is needed is simply not enough for protecting from pollutions. Yes, you may not be exposed to the smoke outside, but that does not mean you are safe! Smoke, pollutants, dust particles enter and leave your car through the windows and the doors! Whenever you open and shut the doors to enter or leave your vehicle, you allow the outside air to come in.

Let’s face it, in today’s world, the climate has become extremely unsafe and unhealthy. The number of deaths due to climate issues are increasing every day. Pollution kills 9 million people every year! Factories are pumping out dangerous chemicals into the air. The number of cars on the road has grown dramatically! Plus, there’s not only that. The number of harmful pollutants has grown as well. There is lead, sulfurous oxides, nitrogen oxides, carbon mono-oxide, benzene, toluene and particulate matter in the air! No matter where you live, it is still there. And it is in extremely unsafe amounts in big cities! These contaminants secretly enter your car and make its interior very toxic, especially due to the air conditioning as the air conditioner recirculates the air inside the vehicle and keeps the contaminants there instead of removing them!

What is HEPA Filter Technology?

HEPA is a technology used to filter air particles. HEPA filters trap particles larger than 0.3 microns. We can see particles that are larger than 10 microns; so particles that are caught in HEPA filter like chemicals, viruses and bacteria cannot be seen to us. HEPA filters trap mold as well. They do not generate ozone or other harmful by products hence they are safe

The HEPA filter is a very very fine fabric that is folded multiple times and used in Air Purifiers so that it creates a mesh of fibre. So the airflow through it becomes hard but the fan speed pushes air through the filter thus trapping the invisible particles inside and leaving clean air outside. When the number of particles increase inside the filter, so much so that it is not able to push clean air outside, then its time to change the filter. I feel it’s a good sign to change filter since we understand that how much impure air we have been living in. You do not have to worry about changing filters frequently because HEPA filters last ranging from 6 months to 4 years too, depending on which area you are staying and using it

Large particles do get caught immediately but smaller particles take 2-3 turns through the filter to be caught.

Air gets filtered in 3 stages –

  1. Inception – Particles come within the radius
  2. Impaction – Large particles get caught
  3. Diffusion – Smallest particles get caught and collide with gases

HEPA filters cannot remove odours, chemicals or gases.

So Companies use Carbon material in their Air Purifiers to absorb odors and gases.

There are many HEPA Filter technology Air Purifiers under Budget reviewed and compared to help you take decision.DO have a look at them too.

What is Activated Carbon Technology?

What is Activated Carbon Technology ?

When carbon is processed to become extremely porous and cover larger area, then that is called Activated carbon technology. This technology is not by defailt used by HEPA filters. SO Air Purifier companies use this technology to manufacture Air Purifiers for removing troublesome Odors

If you ask me, When I had purchased my new office, it was in a brand new building and the smell of paint bothered my eyes so much so that I couldn’t even open my eyes without feeling burning sensation in my eyes. I got rid of that smell by using Carbon Technology enabled Air Purifier. I was doubtful it would work since I thought chemicals are not affecting my throat so probably its not gases that I am inhaling but when it really purified the air inside my office and I could start working in it without disturbing eyes, I decided to write about this technology.

In olden days carbon used to used to filter water, which is used even today in air filters ofcourse. But no one had thought it would help in removing odors too. It was discovered later on that masks made of carbon protected people from Pollution and soldiers from harmful gases. Isn’t that interesting ?

Activated carbon filters are made of molecular sized pores. They have high absorbent ability. That’s why they capture gases, odors, chemical emissions and tobacco smoke. Once caught are caught not to send back again in air.

There is a term called Multiple Chemical Sensitivity in medicine. I personally have that. MCS people absorb formaldehyde quickly and fall sick. Formaldehyde is found in House cleaning liquids, Bathroom cleaning agents, paint, wood paneling and polishes, carpets, upholstery. And when babies are MCS, then they get affected by Asthma because of prolonged exposure.

Many people might think Dust is the main cause of allergy or Pollens and Pet dander, But Bad Odor is equally big reason for many people to fall sick. Many have been diagnosed with eczema and headaches due to bad odors coming from outside their houses. Some go through constipation due to constantly trying not to breath whenever doors or windows are opened.

Carbon air filters reduce contamination of the air for sure.

We have Activated Carbon Technology Air Purifiers researched, reviewed and compared for you convenience. DO go through them.
